California builders risk insurance protects a property, and the materials going into it, while the property is being renovated or built. For a California investor working on a single-family house, a duplex or a fourplex, that is the riskiest stretch of the deal. The house is usually empty. Walls, roofs and plumbing are open. Copper, cabinets and appliances sit on site. And in California the building may sit exposed in a wildfire hazard zone, on an active fault, or below a burn scar, in the hardest property insurance market in the country.

This guide covers California builders risk for investors working on 1 to 4 unit properties: house flips, BRRRR rehabs, value-add work on 2 to 4 unit, and ground-up or infill builds. It explains which policy fits which project, how the wildfire market and the FAIR Plan actually work, what earthquake and flood leave out, what California law requires of your contractor, and how to keep a claim from being cut or denied. It is written for the investor on a first flip and for the one running a dozen at a time.

New to Builder's Risk? Start Here

If this is your first California flip, here is the whole idea in four sentences. A normal home insurance policy is built for someone living in a finished house, so it does not fit a vacant property with open walls and a crew coming and going. Builder's risk is the policy that covers the building and the materials while the work is happening, and it ends when the project ends. Most investors do not buy it on its own; they buy a fix and flip policy that packages builder's risk together with vacant property coverage and liability in one place. The rest of this guide explains the California details, and in this state the biggest of those details is wildfire, which has reshaped how and where coverage can be bought at all.

Key Takeaways

• California builders risk is temporary property coverage for the rehab or build. It does not include liability, so most investors are better served by a fix and flip policy that bundles property, vacancy and liability coverage.
• Wildfire drives the California market. In high fire hazard zones, standard carriers often decline a vacant renovation, and the coverage comes from the California FAIR Plan paired with a wrap-around policy.
• The FAIR Plan covers fire and a few related perils only. It leaves out water damage, theft, liability and more, so it is almost always paired with a Difference in Conditions (DIC) policy to fill the gaps.
• Earthquake is excluded from builder's risk. Earth movement is a separate decision, with its own high percentage deductible, and so is the debris flow that follows a wildfire.
• Flood is excluded and needs a separate policy. California's atmospheric rivers flood neighborhoods far from any coast.
• California has the strictest contractor licensing in the country. Using an unlicensed contractor on work that required a license can force the contractor to return every dollar you paid, and it is a crime.
• New and rebuilt homes in fire hazard zones must meet Chapter 7A ignition-resistant standards and the new Zone 0 ember-resistant rules, which feed directly into ordinance or law coverage.
• Insure to the right value. Underinsuring reduces every claim payment, not only total losses, and a limit raised without your approval costs you premium for nothing.

Which Policy Fits Your Project

The most common insurance mistake we see on a California rehab is buying the wrong kind of policy for the work. Three questions decide the answer: how big is the scope, does anyone live in the building, and are you renovating or building new?

---

---

• Light cosmetic rehab on a vacant house. Paint, flooring, fixtures and similar work can fit a vacant dwelling policy that allows renovation, or a fix and flip policy with a vacancy endorsement. In a wildfire hazard zone, even this can be hard to place in the standard market, and the fire coverage may come from the FAIR Plan with a wrap-around policy for everything else.

• Substantial or structural rehab. Roof replacement, new systems, moved walls and additions call for coverage built for construction risk. Carriers rate structural work higher than cosmetic work because the existing building is more exposed while walls, roofs and floors are open. Describe the scope accurately, because a cosmetic policy on a structural job is a claim dispute waiting to happen.

• Fire rebuild. Rebuilding on a lot cleared by a wildfire is new construction, written on completed value, and it must meet current Chapter 7A and Zone 0 standards. These projects carry their own underwriting questions and belong with a carrier that understands fire-zone rebuilds.

• Rehab with tenants in some units. On a duplex, triplex or fourplex, renovation coverage often allows some occupancy but ends once leasing passes a set share of the units, commonly half. A fix and flip policy may not cover active tenants at all, in which case you need a landlord policy or a hybrid policy, and California's tenant protections make an unplanned occupied unit a legal problem as well as an insurance one.

• Ground-up or infill build. New one to four family homes fit builder's risk new construction coverage, written on completed value from the day materials arrive, and built to Title 24 and, in a fire zone, to Chapter 7A. Add general liability separately.

• The finished rental. Once the property is rehabbed and rented, you no longer need builder's risk. A landlord policy on a dwelling fire special form (DP-3) is the standard fit, and in a fire zone it may again be a FAIR Plan and DIC combination.

Wildfire, the FAIR Plan and the DIC Wrap

In a California fire hazard zone, you often can't buy one normal policy. You buy fire coverage from the FAIR Plan and a second policy to cover everything the FAIR Plan leaves out.

---

---

Why Wildfire Changed Everything

Wildfire is the force that reshaped California property insurance, and the losses explain why. The January 2025 Palisades Fire destroyed 5,316 structures and killed eight people, and the Eaton Fire that burned at the same time destroyed more than 5,000 structures and killed sixteen, among the most destructive fires in state history. The 2018 Camp Fire destroyed 18,804 structures and killed 85 people, the deadliest in the state's record (ABC7). After losses like these, many standard carriers stopped writing, or non-renewed, homes in high fire hazard zones, which is exactly where a lot of investor inventory sits.

How the FAIR Plan Works

The California FAIR Plan is the state's insurer of last resort for fire, created to cover property that the standard market will not. It is not a government program; it is funded by the licensed insurers in the state. Its growth tells the story: it held roughly 668,000 policies in early 2026, up from about 154,000 in 2019.

The catch is what it covers. A FAIR Plan policy covers fire, smoke, lightning and internal explosion, with a few optional add-ons such as vandalism and windstorm. It does not cover water damage, theft, liability, or a long list of other perils. On its own it meets a lender's bare fire requirement and little else.

The DIC Wrap

Because the FAIR Plan leaves so much out, it is almost always paired with a Difference in Conditions (DIC) policy, a wrap-around sold through surplus lines carriers and independent agents. The FAIR Plan handles the fire peril, and the DIC covers the rest: water damage, theft, liability and more. Together they approximate what a single standard policy used to do.

For an investor, three things follow:

• Budget for two policies, not one. In a fire zone, plan for a FAIR Plan fire policy plus a wrap, which together commonly cost more than a single standard policy would have.
• Make sure the wrap actually covers your rehab exposures. A vacant renovation needs theft, vandalism, water and liability, which is exactly what the FAIR Plan leaves out and the wrap has to supply. A fire policy alone is not enough for a lender or for you.
• Check the fire hazard zone before you buy. Whether you can use the standard market or must go to the FAIR Plan depends on the property's fire hazard severity zone, so confirm it early, because it changes both the cost and the structure of the coverage.

Earthquake and Earth Movement

Your builder's risk policy will not pay for an earthquake, and California sits on active faults, so earthquake is a separate yes-or-no decision on every deal.

---

---

Builder's risk and fix and flip policies exclude earth movement, which includes earthquakes. Covering it means a separate earthquake policy or endorsement, and the terms are different from ordinary property coverage:

• The deductible is a large percentage. Earthquake deductibles are set as a share of the insured value, commonly 10 to 25%, not a flat dollar figure. On a total loss that still leaves a lot on you, so earthquake coverage protects against catastrophe, not small cracks.

• It is optional, not required. Lenders rarely require earthquake coverage on a 1 to 4 unit property, so it is a risk decision. On an older unreinforced masonry or soft-story building in a high-shaking area, it is worth pricing. On a wood-frame house, many investors self-insure the risk during a short rehab.

• Disclosure is required at sale. California's Natural Hazard Disclosure statement flags whether a property sits in a seismic hazard, fire or flood zone, so read it on acquisition to understand what you are taking on.

Mudslides and Post-Fire Debris Flow

California carries a compound risk that few other states share: after a wildfire strips a hillside, the first heavy rain can send a debris flow down the burn scar. The Montecito debris flow in January 2018, weeks after the Thomas Fire, killed more than twenty people and destroyed homes that the fire itself had spared.

---

---

For insurance, debris flow falls into the gap between two exclusions. Builder's risk excludes earth movement, and it excludes flood, and a mud and debris flow can be treated as either. If you are rehabbing below a recent burn scar, understand that neither a standard builder's risk policy nor a fire policy is built to respond, and that flood insurance is the coverage most likely to help. Price the exposure before you buy the deal, not after the forecast turns to rain.

Flood in California

---

---

Flood Needs a Separate Policy

Builder's risk and fix and flip policies exclude flood, so a property in a FEMA special flood hazard area needs a separate flood policy, and lenders require one.

Our guidelines set the flood limit at the greater of $250,000 or the loan balance. NFIP flood policies normally have a 30-day waiting period, but FEMA waives it when the policy is purchased in connection with making, increasing, extending or renewing a loan. Private flood policies can carry shorter waiting periods. Buy the flood policy at loan closing.

Atmospheric Rivers Flood Far From the Coast

California's flooding is driven by atmospheric rivers, the long plumes of Pacific moisture that can drop a season of rain in a few days. The storms of recent winters flooded communities in the Central Valley, the Bay Area and the Central Coast, many well outside a mapped flood zone, and burn scars make the flooding worse. A cash buyer with no lender mandate should still price flood on a property with any history of water, and a rental you plan to hold in a special flood hazard area still needs flood insurance under DSCR loan guidelines. Our comparison of landlord and flood insurance explains how the two work together.

California Building Code, WUI Fire Hardening and Ordinance or Law

If your property is in a fire zone, California law dictates how it must be built, and that raises both your rebuild cost and the ordinance or law coverage you should carry.

---

---

Chapter 7A and Ignition-Resistant Construction

California's building code, Title 24, includes Chapter 7A, which sets ignition-resistant construction standards for new buildings in wildland-urban interface and fire hazard severity zones. In practice that means Class A fire-rated roofs, ember-resistant vents, enclosed eaves, multi-pane or tempered windows and noncombustible or ignition-resistant siding and decking (Cal Fire). On a fire rebuild or a ground-up build in these zones, these are requirements, not upgrades, and they change your budget.

The New Zone 0 Ember-Resistant Rule

Under AB 3074, California adopted a Zone 0 standard, an ember-resistant buffer in the first five feet around a structure. The Board of Forestry adopted emergency regulations in 2026 that prohibit combustible fencing, mulch and stored firewood within five feet of the building and require that space be kept clear, with the rules phasing in for new and existing structures over the next several years. If you are rehabbing or rebuilding in a fire zone, build the Zone 0 requirements into the scope and the landscaping plan.

Why Ordinance or Law Coverage Matters More Here

Ordinance or law coverage pays for costs that come from enforcing current building codes after a covered loss: the value of the undamaged portion code forces you to tear down, the cost to demolish it, and the added cost to rebuild to current code. In California, a partial fire loss on an older house can trigger a full Chapter 7A rebuild of the damaged portion, which is far more expensive than replacing what was there. Many policies default to 10 percent of the building limit. On fix and flip quotes our team typically requests 25%, and California's fire code is exactly why that higher limit matters.

Surplus Lines, the FAIR Plan and Carrier Strength

A lot of California renovation coverage comes from insurers the state does not back if they fail, so the carrier's rating and the total cost matter more than the headline premium.

---

---

Many California fix and flip, vacant home and DIC policies come from surplus lines carriers. These are insurers not licensed in California the same way as standard carriers, but allowed to cover risks the admitted market declines, which describes most vacant renovations in a fire zone. Two points belong on every quote review.

• The tax. California charges a surplus lines premium tax of 3% of premium, plus a small stamping fee paid to the Surplus Line Association of California. Compare quotes on total cost, not base premium.

• No guaranty fund, and a FAIR Plan that is stretched. If an admitted California insurer fails, the California Insurance Guarantee Association pays covered claims within limits. Surplus lines policyholders do not have that protection. The FAIR Plan itself has asked regulators for a large average rate increase as its exposure has grown, a reminder that last-resort coverage is not cheap coverage. All of this is why lenders require an AM Best rating of A- VIII or better, and why our team checks it on every quote. Our guide to AM Best ratings explains what the rating means.

How Much California Builders Risk Costs

California is the most expensive state in this guide to insure a rehab, and wildfire is the reason. Here is the range OfferMarket investors typically see on 1 to 4 unit California deals, by property value and rehab budget:

---

---

These ranges cover the property and renovation coverage. A property in a high fire hazard zone that needs a FAIR Plan and a wrap prices above these ranges, sometimes well above, and the structure of the coverage changes too. Two more things are worth knowing. California fix and flip premiums have risen more than 25% in the last 18 months, and in our experience a typical policy is quoted close to a third above what the deal actually needs, usually from padded limits and endorsements the investor never asked for. Closing that gap is what our quality control is built to do.

For context, builder's risk nationally runs about 1 to 4 percent of completed value, and standalone policies carry a minimum premium floor regardless of project size. Because California pricing swings so widely with the fire hazard zone, the only reliable number is a quote on your property. For bundled rehab coverage, see our fix and flip insurance guide.

Refunds When the Project Ends Early

OfferMarket fix and flip premiums are generally refunded pro rata when you cancel early, most often after a sale or after refinancing into a DSCR loan and switching to landlord insurance. Not every policy works that way. Some new construction policies, and some FAIR Plan terms, are fully or minimally earned, which limits a refund for unused time. Ask before you bind.

What Factors Influence California Builders Risk Cost?

The cost of builder's risk insurance comes down to the specific risks of your project and in California, one issue easily overshadows the rest. While most insurance companies base their pricing on five main factors, our team looks at three additional details that make or break an investor deal.

1. Location

Where the property sits is the single biggest driver of cost, and in California it can decide whether coverage is available at all. Carriers look at:

• The fire hazard severity zone and distance to wildland fuel
• Seismic hazard and fault proximity
• Flood zone and burn-scar debris-flow exposure
• Distance to a fire station and the local fire protection class
• Crime and vandalism rates on the block

You cannot move the building, but you can make sure the quote is built on the right address, fire hazard zone and protection class. An error in any of these changes the premium or the market you are placed in.

2. Project Type

Carriers rate new construction, installation and remodeling differently, based on how much the existing structure adds to the risk.

• New construction and simple installations usually cost the least, because the timeline is short and there is no existing building to protect.
• Remodeling is rated highest, because an existing structure is exposed the entire time the work is underway.
• A cosmetic remodel rates lower than a structural remodel that moves load-bearing walls or adds a story.

Describe the scope accurately. Understating it to shave premium is the fastest way to have a large claim disputed.

3. Construction Type

The materials the building is built from decide how well it survives a fire or quake.

• Masonry and fire-resistive construction rate well for fire, though unreinforced masonry rates poorly for earthquake.
• Wood frame is most of California's housing stock and rates least favorably for wildfire, which is what Chapter 7A hardening is meant to address.

4. Optional Coverages

The base policy covers the core perils. Every endorsement adds premium, so match them to the project. On a California rehab the options worth discussing are:

• Flood, which is excluded as standard
• Earthquake, where the risk warrants it
• The DIC wrap, when fire coverage comes from the FAIR Plan
• Soft costs: extra loan interest, taxes and fees during a covered delay
• Loss of rents, for units with tenants
• Materials in transit and in temporary off-site storage

5. Additional Fees and Taxes

Two policies with similar base premiums can cost very different amounts once fees and taxes are added, and that comes down to the type of carrier.

• Admitted carriers are licensed in California and backed by the California Insurance Guarantee Association if the insurer fails.
• Non-admitted (surplus lines) carriers write many vacant, renovation and DIC policies that admitted carriers decline. They add the 3% surplus lines tax and a stamping fee, and they are not backed by the guaranty fund.

Compare quotes on total cost, not the base premium, and require an AM Best rating of A- VIII or better.

Three More Factors We Weigh for Investors

• Vacancy and timeline. A building that has sat empty for years, or a project expected to run past 12 months, carries more risk and often more premium, and a long fire-season exposure raises it further.

• The limit. Set it on completed value, without land and without padding. In California, land is often most of the market value, so the gap between market value and insurable rebuild cost is wide, and this is where overpayment hides.

• The deductible. A higher deductible lowers premium, but lenders cap it. Our guidelines cap the property deductible at the lesser of 5 percent or $5,000, separate from the percentage wildfire or earthquake deductibles that apply to those perils.

How to Lower Your California Builders Risk Cost Without Creating a Gap

You can bring the premium down without leaving a hole in the coverage:

• Insure to an accurate completed value, without padding, and keep land out of the limit
• Harden the building: a Class A roof, ember-resistant vents and Zone 0 clearance can help both insurability and the finished rental's premium
• Choose the highest deductible your lender accepts and your reserves can absorb, within the cap
• Secure the site with locks, lighting and cameras
• Keep the schedule realistic, so you avoid extension charges and a long fire-season exposure
• Compare quotes line by line, and question any limit or endorsement you did not request

Never save money by dropping vacancy, the DIC wrap, liability or theft protection. In California those gaps are exactly where the uninsured losses happen.

What Our Quality Control Catches on Outside Quotes

Every quote that comes through OfferMarket is checked by our QC team against the investor's request and the lender's guidelines before it is bound. These are the problems we flag most often, and the reason we tell investors never to judge a quote by the premium alone.

• A FAIR Plan policy with no wrap. A fire-only FAIR Plan policy quoted as if it were full coverage, with no DIC to cover theft, water, vandalism or liability. On a vacant rehab, those are the losses most likely to happen.

*`The wrong policy type for the project. A landlord policy quoted on a vacant gut rehab, or a vacant renovation program quoted on a property the investor plans to rent right away.

*`A dwelling limit the investor did not ask for. Agents sometimes raise or lower the limit without approval. Raising it adds premium for coverage you could never collect. Lowering it can trigger a coinsurance penalty on every claim. This is the single biggest source of the overpayment we see on California quotes.

• Functional replacement cost in place of replacement cost. The two look similar on a summary page, but functional replacement cost can pay noticeably less on an older house, and it interacts badly with a Chapter 7A rebuild requirement.

• Land value folded into, or out of, the limit incorrectly. California land values distort the math in both directions. We confirm the limit is built on rebuild cost, not market value.

• Thin ordinance or law coverage. Many quotes default to 10%. On fix and flip policies, we request 25 percent, which matters more in California because of the fire code.

• No vacancy endorsement. A vacant renovation quote with no vacancy endorsement is a denied claim waiting to happen.

• Liability below lender limits. Fix and flip policies need $1,000,000 per occurrence and $2,000,000 aggregate. Landlord policies on our DSCR loans need $500,000 per occurrence.

• *Mortgagee and additional insured confused.** The lender needs to be the mortgagee on the property coverage and an additional insured on the liability coverage, on both the FAIR Plan and the wrap when the coverage is split.

Cases From Our Quality Control Desk

These are real situations our team handled, anonymized and summarized.

• The fire policy that covered only fire. An investor on a hillside rehab received a FAIR Plan quote that looked complete and affordable. Reading it, our team saw there was no wrap, which meant theft of the new copper and appliances, water damage from a burst line, and any liability claim would all be uninsured. We added a DIC policy so the coverage actually matched the exposure. The lesson: in a fire zone, a FAIR Plan quote by itself is a fire policy, not a renovation policy.

• The limit built on the land. A Bay Area quote came back with a dwelling limit far above the rebuild cost, because the agent had anchored it near the purchase price, most of which was land. The investor was paying for coverage that could never be collected. We rebuilt the limit on replacement cost of the structure. The lesson: in California, the land is not insurable, and pricing the policy on market value is how you overpay.

• The unlicensed crew. An investor lined up a low-bid crew that turned out not to hold a California contractor license for the work. Beyond the insurance risk, we flagged the legal one: under California law the owner could be forced to recover, and the contractor could be ordered to return, every dollar paid, and the work would not satisfy the lender's draw inspections. The investor switched to a licensed contractor before work began. The lesson: in California, the contractor's license is not paperwork, it is the difference between an enforceable job and a crime.

• The rebuild that triggered the code. On a partial fire loss, an older house needed its damaged portion rebuilt to current Chapter 7A standards, at a cost the base policy would not fully cover. Because the investor carried ordinance or law at 25 percent rather than the default 10, the code upgrade was paid. The lesson: in a fire state, ordinance or law coverage is not optional padding.

What Your Lender Requires

The property is your lender's collateral, so the lender's insurance guidelines shape the policy as much as your own preferences do. This table compares typical requirements during the rehab with the requirements after a refinance into a DSCR loan.

---

---

---

The mortgagee clause. List the lender's exact name and address followed by ISAOA/ATIMA. OfferMarket's clause reads OfferMarket Capital LLC ISAOA/ATIMA, 627 S Hanover St, Baltimore, MD 21230. When the coverage is split between a FAIR Plan policy and a wrap, the lender is listed on both. More detail is in our mortgagee clause glossary entry.

Proof of insurance. OfferMarket requires an ACORD form, plus certificates and paid receipts, at least 24 hours before closing, and final policy documents within 60 days after closing.

Carrier strength. An AM Best rating of A- falls in the Excellent category, and Financial Size Category VIII means policyholder surplus of $100 million to $250 million. This matters more in California, where many renovation and DIC policies are written in the surplus lines market with no guaranty fund backstop.

Why Financing and Insurance in One Place Matters

Most closing delays caused by insurance come down to a mismatch between the policy and the loan: a FAIR Plan policy with no wrap, a deductible the lender will not accept, a limit too low, a flood policy bound too late or a mortgagee clause missing from one of the two policies. When you use OfferMarket Capital for the loan and OfferMarket Insurance to rate-shop the coverage, the same team that sets the loan requirements checks the policy against them before closing, not the day before.

---

---

What California Builders Risk Covers on a 1 to 4 Unit Project

Coverage depends on the policy form, so treat this section as a list of things to confirm rather than a promise of what any one policy includes.

---

---

The Building and the Work

On a renovation, two values are at risk: the building you bought and the work you are adding. Not every builder's risk policy insures both.

For an investor, the loss that matters most is a fire that takes the whole building, not only the new kitchen. Confirm in writing that the existing structure is insured from the day you close, and in a fire zone confirm where that fire coverage comes from.

Materials on Site, in Storage and in Transit

Building materials are often the easiest thing to lose. OfferMarket's renovation coverage insures the structure, materials and equipment on the premises or within 100 feet, and the foundation.

If materials will be stored off site, ask for coverage at that location by name. A pallet of flooring or a staged HVAC unit sitting at another address is outside a site-only policy.

The Causes of Loss

Residential builder's risk commonly covers fire and lightning, wind and hail, theft, vandalism, arson, collapse and water damage from burst pipes. In a FAIR Plan and DIC structure, the fire peril sits on the FAIR Plan and the rest sits on the wrap, so read both. Many policies add extensions such as debris removal, materials in transit and ordinance or law, each with its own smaller limit. Ask for the sublimit on each one, especially debris removal, which is expensive after a fire.

Theft: The Claim Investors Misunderstand Most

Theft is one of the most frequent construction claims, and residential job sites have predictable targets: copper wiring and pipe, appliances, HVAC condensers and fixtures. In a FAIR Plan structure, theft is not covered by the FAIR Plan at all, so it has to be on the wrap.

Some policies exclude theft of building materials that are not yet attached to the structure. Before materials arrive, ask three questions:

• Is theft of uninstalled materials and appliances covered on site, in storage and in transit?
• Is there a sublimit?
• What security conditions apply? Then schedule deliveries as close to installation as your contractor allows.

Ordinance or Law for Older and Fire-Zone Buildings

When a damaged building is rebuilt, code can require upgrades to undamaged parts of the structure, and in a California fire zone that means Chapter 7A. Ordinance or law coverage pays for the value of the undamaged portion code forces you to tear down, the cost to demolish it, and the increased cost to rebuild to code. On fix and flip quotes, our standard is 25% of the building limit, not the common 10 percent default.

What California Builders Risk Does Not Cover

---

---

• Earthquake and earth movement. Excluded. Covering it means a separate earthquake policy or endorsement with a large percentage deductible.

• Flood and debris flow. Excluded. Rising water, and the mud and debris flow that follows a wildfire, are flood or earth movement claims, not property claims, and need separate coverage.

• The perils the FAIR Plan leaves out. If your fire coverage is a FAIR Plan policy, then theft, water damage, liability and more are not covered unless a wrap supplies them. This is the most important California-specific gap to understand.

• Pre-existing damage. A damaged building bought as is will not be covered for damage that existed before the policy started. Dated photos at closing protect you.

• Faulty workmanship and defective materials. Builder's risk is not a warranty. Policies generally exclude the cost to correct faulty work, though an ensuing loss provision may cover resulting damage to other property.

• Wear and tear, rot, pests and mold. Gradual deterioration and infestation are maintenance problems. Mold coverage is often excluded or capped.

• Employee theft and worker injuries. Theft by the crew and injuries to workers are excluded. Worker injuries belong under the contractor's workers' compensation, which California law requires.

• Liability. A standalone builder's risk policy does not cover injuries to other people. The liability section below explains how to fill this gap.

• Land and landscaping. Land, trees, shrubs and walkways are generally not covered, and land value should never be part of your limit.

Vacancy: The Empty-Building Problem

Most flips start with a vacant building, and standard policies often exclude or void coverage on unoccupied buildings. More investor claims go wrong here than anywhere else.

---

---

How Vacancy Clauses Work on Residential Policies

In the standard homeowners form, coverage for glass breakage and vandalism ends once the dwelling has been vacant for more than 60 consecutive days. Dwelling policies work much the same way, and some older forms use 30 days. The FAIR Plan has its own vacancy rules, which is one more reason to confirm how a fire-zone property is covered.

Why "Under Renovation" May Not Protect You

Many policies say a home under construction is not considered vacant, but renovation can be treated differently. Gutting a building, with the contents removed and the occupants gone, can make it vacant, and visiting to check on progress does not change that. Merlin Law Group states courts look for substantial, continuous construction activity, measured by how many workers were on the project and how much time they spent in the building.

The Fix

Disclose vacancy when you apply, and make sure the policy carries a vacant property endorsement or vacancy permit for the whole rehab period. Our lending guidelines require borrowers to notify the carrier when a property becomes vacant or unoccupied and to obtain a vacancy permit for the entire vacancy period. Back the endorsement with records: a dated work log, contractor invoices, inspection reports and weekly photos.

Liability on a Rehab

A builder's risk policy does not cover workplace injuries or liability. On an investor rehab, the liability exposure often outweighs the property exposure, which is why we pair renovation coverage with general liability on every fix and flip quote.

---

---

• Who can get hurt. Contractors and their crews, inspectors, appraisers, buyers' agents, neighbors and trespassers.

• Children and open job sites. Under the attractive nuisance doctrine, landowners may owe trespassing children a heightened duty when a dangerous condition is likely to attract them (Cornell Legal Information Institute). Open foundations and unsecured stairs are exactly that kind of condition. Fence and lock the site.

• What lenders require. Fix and flip lenders commonly require general liability of $1,000,000 per occurrence and $2,000,000 aggregate on an occurrence basis, with the lender as additional insured.

• Your contractor's coverage, and the law. California requires licensed contractors to carry workers' compensation, and the licensing rules below make the contractor's coverage your concern too. Collect certificates of general liability and workers' compensation before work begins, and ask your contractor to add you as an additional insured.

Contractor Licensing in California

California has the strictest contractor rules in the country. Hire an unlicensed contractor for work that needed a license, and the law can make them give back everything you paid, even if the work was good.

---

---

Almost every rehab in California must be performed by a contractor licensed through the Contractors State License Board (CSLB), and the rules carry real teeth.

• When a license is required. A license is required for any job of $1,000 or more in combined labor and materials, and for any work that needs a building permit or uses employees. In practice, that covers nearly every flip.

• The class. Class B, General Building, is the core general contractor license, used when a project involves at least two unrelated trades. Specialty trades carry their own C classifications.

• Unlicensed work is a crime, and worse for your wallet. Contracting without a license on covered work is a misdemeanor, with fines up to $5,000 and up to six months in jail for a first offense. Under Business and Professions Code section 7031, an unlicensed contractor cannot sue to collect a dollar, and the owner can sue to recover every dollar already paid, even if the work was done well.

• Bond and workers' compensation. Every licensed contractor must carry a $25,000 license bond, and under SB 216 the requirement to carry workers' compensation is being extended to all licensed contractors, even those with no employees. Confirm both are current.

For an investor, the takeaway is simple: verify your contractor's license on the CSLB website before work begins, and keep the number on file. A cheap unlicensed bid is the most expensive mistake you can make in this state.

How to Set the Right Limit

---

---

Insure to Completed Value, Not Market Value

Builder's risk limits are based on the estimated completed value of the structure, which in California is often far below the market value because land carries so much of the price. When the limit falls short of rebuild cost, many forms reduce claim payments in proportion. When it is set on market value, you overpay for coverage you can never collect. The target is the rebuild cost of the finished building.

Our Completed Value Worksheet

• Rebuild cost of the existing structure. Not the purchase price and not the land.
• Full rehab budget. Materials and labor.
• Contractor overhead and profit. Up to 20% of completed value.
• California code costs. Title 24, and Chapter 7A and Zone 0 in a fire zone, which are significant.
• Minus land. Land is never part of the insured value, and in California it is often most of the market price.

ARV Is Not Replacement Cost

Investors think in after-repair value. Insurers think in rebuilding cost. Use the ARV calculator for market value, and ask for a replacement cost estimate on the structure itself.

When the Loan Sets the Limit

Our fix and flip guidelines set the property limit at replacement cost, taken from the appraisal or a replacement cost estimator, or at the loan amount. If the loan amount is below replacement cost, the policy must be written on an agreed value basis or carry zero coinsurance.

When Coverage Starts and Ends

---

---

Starting Coverage

Bind coverage before you close, because your lender, or your title company on a cash purchase, will require proof of insurance. In a fire zone, start the FAIR Plan and wrap process early, because it takes longer than a standard bind. On new construction, have builder's risk in place by the time materials are delivered.

Buying Coverage in the Middle of a Rehab

You can often buy coverage after work has started, but you must disclose the work already done, and some insurers require an inspection or limit certain coverages. Expect more questions the further along the project is.

What Ends Coverage

Builder's risk ends automatically, often without a reminder, when a termination trigger occurs:

• Ownership transfers to the buyer.
• A set period passes after construction is complete.
• The property is occupied or put to its intended use.
• A single-family home is leased or rented.
• A set share of the units in a 2 to 4 unit building is leased.
• Permanent property insurance takes effect.
• Your interest in the property ends, or you abandon the project.
• The policy term expires.

The Early Tenant

On a BRRRR project, a tenant moving in can end builder's risk on the spot. On a duplex or fourplex, leasing half the units can do the same. Bind the landlord policy first.

Handing Off to Landlord Insurance

If you keep the property, put the landlord policy in effect before you cancel the old one, send the new policy details to your servicer, and send the servicer's information to the new carrier. If you sell, cancel after the transfer closes and request your pro rata refund.

California Playbooks by Market and Strategy

---

---

Los Angeles and the Wildland-Urban Interface

From the Palisades to the foothill communities of the San Gabriel Valley, large parts of the LA market sit in or near a fire hazard zone. Confirm the fire hazard severity zone before you buy, plan for a FAIR Plan and wrap where the standard market declines, build Chapter 7A and Zone 0 into any rebuild, and carry ordinance or law at 25%. This is the market where the wildfire playbook matters most.

The Bay Area and Seismic Risk

The Bay Area, from San Francisco and Oakland to San Jose, combines very high land values with real seismic exposure on the Hayward and San Andreas faults. Insure the structure on rebuild cost, not the sky-high market price, price earthquake on older unreinforced or soft-story buildings, and watch the East Bay hills for fire zone overlap.

The Inland Empire and Central Valley

Riverside, San Bernardino, Sacramento, Fresno and Bakersfield offer lower acquisition prices and strong flip and rental demand. Fire exposure varies block by block at the wildland edge, flood and atmospheric-river risk shows up along the rivers, and these are the markets where a clean, well-priced policy is easiest to place.

Fire Rebuilds

Rebuilding on a lot cleared by a wildfire is new construction under current code. Insure to full completed value including the Chapter 7A and Zone 0 cost, place the coverage with a carrier that understands fire-zone rebuilds, and confirm the contractor's license and workers' compensation before the first inspection.

BRRRR in California

Use the rehab to set up the rental: a hardened roof, updated systems and documented fire-zone compliance before you shop the landlord policy. Get the landlord and flood quotes through OfferMarket, then run the refinance math with the DSCR calculator. Our BRRRR method guide covers the full strategy.

The Rental Exit: A Cheaper California Landlord Policy

The rehab is the best chance to lower the cost of insuring the finished rental, which in California is no small thing.

• Harden the building. A Class A roof, ember-resistant vents and Zone 0 clearance can improve both insurability and the landlord premium in a fire zone, and may keep the property in the standard market instead of the FAIR Plan.

• Document everything. Keep permits, the contractor's license, fire-hardening records and photos of the completed work. An insurer rating the finished rental rewards a building that is demonstrably updated and hardened.

• Bind the landlord coverage before the tenant moves in. Occupancy can end builder's risk, so put the landlord insurance in place first, then cancel the rehab policy and request any pro rata refund. Our DWG-3 policy guide explains how landlord property coverage works.

Completed value. The expected value of the finished structure, not the market value with land. Builder's risk limits are set on this number.

FAIR Plan. California's insurer of last resort for fire, used when the standard market declines a property. It covers fire and a few related perils only.

Difference in Conditions (DIC). A wrap-around policy that covers the perils the FAIR Plan leaves out, such as theft, water and liability.

Fire hazard severity zone. The state's classification of wildfire risk for a location, which drives whether coverage comes from the standard market or the FAIR Plan.

Chapter 7A. The part of the California Building Code requiring ignition-resistant construction in fire zones.

Mortgagee clause and ISAOA/ATIMA. The mortgagee clause protects your lender's financial interest. ISAOA means "its successors and/or assigns," and ATIMA means "as their interests may appear."

Replacement cost and actual cash value. Replacement cost pays to repair or rebuild without deducting depreciation. Actual cash value subtracts depreciation, so an older roof or system pays out far less.

Coinsurance and the 80 percent rule. Many property policies require you to insure a minimum share of value, often 80 percent. Insure for less, and the policy reduces every claim payment in proportion.

Vacancy permit. An endorsement that restores coverage a vacancy clause would otherwise take away.

Builder's Risk Insurance Guidelines

Below are common builder's risk insurance guidelines for fix and flip loans (otherwise known as hard money loans). These coverage limits are generally considered best practice from a risk management perspective.

The OfferMarket Builder's Risk Recipe

Our insurance team uses this seven-step method to structure renovation coverage for 1 to 4 unit California investors.

---

---

1. Check the fire hazard zone first. It decides whether coverage comes from the standard market or a FAIR Plan and wrap, and it changes everything downstream.

2. Classify the project accurately. Cosmetic rehab, structural remodel, fire rebuild or ground-up build. Disclose work already started, vacancy history, tenants and timeline.

3. Set the limit on rebuild cost. Start from the rebuilding cost of the finished structure and your lender's guideline. Include California code costs, and exclude land.

4. Structure the fire coverage. In a fire zone, pair a FAIR Plan fire policy with a DIC wrap that covers theft, water, vandalism and liability.

5. Add the California decisions. Earthquake where the risk warrants it, flood where required, and ordinance or law at 25 percent.

6. Add general liability at lender limits, with the lender as additional insured, and confirm the contractor's CSLB license and workers' compensation.

7. Bind early and plan the exit. Fire-zone placement takes longer, so start before closing, use the exact mortgagee clause on both policies, and line up the landlord coverage before the tenant moves in.

Frequently Asked Questions

Do I Need Builder's Risk Insurance for a Flip in California?

If the building is vacant and under renovation, a homeowners policy is the wrong fit, and lenders require property and liability coverage before closing. A fix and flip policy that includes builder's risk features, a vacancy provision and general liability is the common solution, and in a fire zone the fire portion may come from the FAIR Plan with a wrap.

What Is the FAIR Plan, and Do I Need the DIC Wrap?

The California FAIR Plan is the insurer of last resort for fire, used when standard carriers decline a property. It covers fire and a few related perils only, so it is almost always paired with a Difference in Conditions wrap that adds theft, water, liability and the rest. On a vacant rehab, the wrap is where most of your real exposure sits, so yes, you generally need it.

Does California Builders Risk Cover Wildfire?

Fire, including wildfire, is a covered peril, but in a high fire hazard zone the standard market may decline the risk, and the fire coverage then comes from the FAIR Plan. The key is confirming the fire hazard zone and how the fire peril is being placed.

Does Builder's Risk Cover Earthquakes in California?

No. Earthquake is earth movement, which builder's risk excludes. Covering it means a separate policy or endorsement with a large percentage deductible, commonly 10 to 25% of the insured value.

Do I Need a Licensed Contractor in California?

Almost always. A CSLB license is required for work of $1,000 or more, or any job needing a permit. Using an unlicensed contractor on covered work is a crime, and under Business and Professions Code 7031 you can recover every dollar you paid. Verify the license before work starts.

How Much Does California Builders Risk Cost?

It depends on the property, and above all on the fire hazard zone. As a guide, OfferMarket investors see roughly $1,100 to $2,200 a year on a $150,000 property with a $50,000 rehab, $1,800 to $2,900 on a $300,000 property, and $2,500 to $3,900 on a $500,000 property, with fire-zone properties on a FAIR Plan and wrap pricing higher. Nationally, builder's risk runs about 1 to 4 percent of completed value.

Is OfferMarket Licensed in California?

OfferMarket Insurance LLC (NPN 20545557) holds insurance licenses in a number of states, listed on our licenses page, but it is not yet licensed in California. OfferMarket operates a rate-shopping platform: on California properties, we compare quotes across carriers licensed in California, who quote, bind and service the policy, and our team quality-checks each quote before you bind.
