Builder's risk insurance
Builder's risk insurance is property insurance on a building while it is being built: the structure, its foundation, and the fixtures and materials meant to become part of it, on the site or within 100 feet of it. On ISO's standard form it ends when the policy expires, the buyer accepts the property, construction is abandoned, or, unless the carrier agrees otherwise, 90 days after completion or 60 days after occupancy. The usual reason to buy it is a construction lender or contract that requires it. Mercantile Bank requires it before draws; Michigan First wants it at signing for at least the loan amount; MSU Federal Credit Union wants itself named as mortgagee.

What is builder's risk insurance?
It is a property policy written for the period of construction. ISO's Builders Risk Coverage Form, CP 00 20, defines the covered property as the "Building Under Construction," including foundations, fixtures and machinery, equipment that services the building, and "your building materials and supplies used for construction," as long as they are meant to be permanently located in or on the building or within 100 feet of the premises. Temporary structures built on site, such as scaffolding and construction forms, are covered if no other insurance covers them. Land is not.
The form does not list perils itself; it points to a causes-of-loss form shown on the declarations. Two details on the ISO special form matter on a job site. It excludes earth movement, including earthquake, and flood. And it limits loss to "building materials and supplies not attached as part of the building or structure, caused by or resulting from theft," so a load of lumber stolen before it is installed may not be covered unless the policy adds theft of materials back. Ask which causes-of-loss form and which endorsements are on the quote.
Builder's risk is not liability insurance. It covers the structure; a claim that someone was hurt on the site or that the work damaged a neighbor's property is general liability, a separate policy, and a project may require both.
Do I need builder's risk insurance?
You need it when a lender or a contract requires it, and every construction lender page we read for this page did: Mercantile Bank, Michigan First, MSU Federal Credit Union, Capital City Bank and WHEDA. Regulators look for it too. Michigan's Office of Credit Unions directs examiners to check that a credit union's construction lending policy requires builder's risk insurance, next to requiring permits before loan money goes out.
Without a loan, ask who carries the loss if the half-built structure burns. If the contract puts it on the builder, ask for the builder's policy and check it covers your project at the completed value.
What are construction loan insurance requirements?
Every lender writes its own list, and the list is the document to satisfy; the lists differ. Mercantile Bank makes builder's risk "Mandatory for loan approval and draw disbursements." Michigan First Mortgage asks for a builder's risk policy "in at least the amount of the loan," with a paid receipt for the first year's premium, at the time the loan documents are signed, plus coverage for theft of materials. MSU Federal Credit Union requires the builder or homeowner to provide builder's risk naming the credit union as mortgagee, with its exact ISAOA address, before closing. WHEDA, Wisconsin's housing finance agency, in its requirements for the multifamily developments it finances, sets the limit at "100% of the development's Mortgage Amount at completion" and accepts only carriers rated A-, VII or better by A.M. Best.
Lenders also look past builder's risk. WHEDA lists a certificate of liability insurance, evidence of property insurance, or builder's risk as evidence of coverage at closing. Capital City Bank requires flood insurance when the property is in a Special Flood Hazard Area. Separately, federal rules apply to banks: the FDIC's rule bars an FDIC-supervised institution from making a designated loan, one secured by a building in a special flood hazard area, unless the building is covered by flood insurance, and it defines a building to include a structure "while in the course of construction."
The mortgagee wording matters because it gives the lender rights of its own. Under CP 00 20, a mortgageholder shown in the declarations is paid "as interests may appear" and gets written notice at least 10 days before cancellation for nonpayment and 30 days before cancellation for any other reason. Property evidence goes on an evidence of property form; the ACORD 27 vs ACORD 28 page covers which one.
How much does builder's risk insurance cost?
The one published figure we found is a broker's report on its own customers. Insureon reports an average of $105 a month, or about $1,259 a year, calculated as a median of policies sold to its small business customers, and says most pay from about $350 to over $7,000 a year (page updated July 2, 2026). Treat it as a reference point, not a quote.
The limit is the one number not to shave. CP 00 20's Need For Adequate Insurance condition says the carrier will not pay a greater share of any loss than the limit bears to the building's value on the date of completion. The form's own example: a building worth $200,000 at completion, insured for $100,000, has an $80,000 loss; the carrier pays $39,500 and the owner carries the rest. Insure to the completed value, without the land.
Is builder's risk insurance different in Texas, Florida and California?
What varies by place is which perils a carrier will take at your address and what the lender adds, so read the causes-of-loss form and every exclusion endorsement.
Texas. On the coast, a private carrier can remove wind from a policy with an endorsement such as ISO's CP 10 54 Windstorm or Hail Exclusion. The Texas Windstorm Insurance Association writes wind and hail coverage in the first-tier coastal counties for owners declined by a licensed insurer. A 2020 specimen TWIA application filed with the Texas Department of Insurance lists a builder's risk stated value form; ask TWIA or your agent whether it is offered for your project today. TWIA requires a windstorm certificate of compliance for the structure, and TDI has certified ongoing improvements since June 1, 2020, so start the inspection process when construction starts, not at the end.
Florida. We found no Florida-specific builder's risk rule. Ask whether wind is covered or excluded at your address, and expect the flood question if the lot is in a Special Flood Hazard Area: Capital City Bank requires flood insurance there, and the FDIC's definition of a building reaches structures under construction.
California. The ISO special form excludes earthquake, including tremors, aftershocks and related earth movement. If the lender or your own exposure calls for earthquake cover, ask the carrier for it by name. We did not find a California-specific builder's risk rule in the sources we checked.
When does builder's risk for new construction start and end?
It should start before the first materials arrive, and on a financed build no later than closing; MSU Federal Credit Union states that no work shall commence before closing. It ends on its own terms. CP 00 20 stops coverage at the first of these: the policy expires or is cancelled, the purchaser accepts the property, your interest ends, you abandon the construction, or, unless the carrier agrees otherwise in writing, 90 days after construction is complete or 60 days after the building is occupied in whole or in part or put to its intended use.
That last clause catches owners who move in early. A renovation written on CP 11 13 is different: that endorsement switches off the 90- and 60-day cutoff. Michigan First tells its borrowers that once the certificate of occupancy is issued, a homeowners policy must replace builder's risk; Mercantile describes builder's risk as running from the start of construction until the certificate of occupancy.
What is vacant builder's risk?
The phrase is used for renovating an existing, empty building, and two ISO forms bear on it. The Builders Risk Renovations endorsement, CP 11 13, covers the value of the "improvements, alterations or repairs" and says plainly that covered property does not include "the value of buildings or structures existing prior to construction." Ask how the existing structure itself is insured.
That property policy has a vacancy condition. On ISO's Building and Personal Property form, CP 00 10, a building vacant for more than 60 consecutive days loses coverage for vandalism, theft, water damage and several other causes, and other losses are cut by 15%. The same form says buildings under construction or renovation are not considered vacant, so tell the carrier when work starts and if it stops.
Should the contractor or the owner buy builder's risk insurance?
Either can; the contract decides, and the lender has to accept the result. Mercantile Bank and Michigan First both say builder's risk may be purchased by the builder or the homeowner. Whoever buys it, the other party's interest has to be on it. WHEDA, for example, requires the project owner to be an additional insured as its interest may appear when the general contractor buys the policy.
A contractor buying it should check two limits in CP 00 20. Building materials and supplies owned by others in the contractor's care are covered only up to $5,000 per premises unless the declarations show more. And the carrier will not pay an insured more than its financial interest in the property, so check that each party with an interest is shown on the policy.
Is builder's risk the same as course of construction insurance?
Michigan First Mortgage treats them as the same thing. Ask your lender whether it does.
Can I get a certificate of insurance for builder's risk?
It depends on the lender's list. WHEDA, for example, accepts a certificate of liability insurance, evidence of property insurance, or builder's risk as evidence at closing. Ask the agency for the form your lender names, with its exact wording, and send the lender's insurance letter with the request.
Does builder's risk cover my tools and equipment?
CP 00 20 does not list them: its covered property is the building and the fixtures, equipment and materials meant to become part of it. Ask about tools and contractor's equipment as a separate coverage.
