Yes — if you are renovating a building, you almost certainly need builders risk insurance. Standard commercial property policies exclude physical damage that occurs during active construction or renovation work. Builders risk fills that gap, covering the structure, materials, and equipment on-site from the date work begins until the project reaches substantial completion.
Who this is for: Property owners, general contractors, and developers undertaking commercial or residential renovation projects of any size.
TL;DR / Key Takeaways
- Your existing property policy likely does not cover damage that occurs during renovation — most policies contain a "vacancy" or "under construction" exclusion that voids coverage once active work begins.
- Builders risk is a temporary, project-specific policy; it activates at groundbreaking (or material delivery) and expires at substantial completion or occupancy — whichever comes first.
- Coverage typically includes the structure, permanently installed materials, scaffolding, and temporary structures — but not workers' tools, contractor errors, or earth movement unless endorsed.
- Lenders almost universally require builders risk before releasing construction draws on renovation loans.
- The cost runs roughly 1%–4% of the total construction budget for most commercial renovation projects, with the exact rate driven by project type, location, and coverage options.
What Does Builders Risk Actually Cover During a Renovation?
Builders risk is a specialized first-party property coverage (most often written on an inland marine form) on an "all-risk" or "open-perils" basis, meaning it pays for losses not specifically excluded. For a renovation, standard coverage typically includes:
| Coverage Element | Typically Included | Common Exclusions / Requires Endorsement |
|---|---|---|
| Existing structure (pre-renovation building) | Yes — if scheduled on the policy | Sometimes excluded; confirm with insurer |
| New materials stored on-site | Yes | Off-site storage may require endorsement |
| Scaffolding and temporary structures | Yes | Separate sublimit may apply |
| Soft costs (architect fees, permit re-fees) | Endorsement available | Not in base policy |
| Business income / delay in opening | Endorsement available | Not in base policy |
| Contractor's tools and equipment | No — covered under inland marine / tool floater | — |
| Faulty workmanship / design error | No — excluded universally | Some policies cover resulting damage |
| Earthquake and flood | No | Separate policies or endorsements |
| Workers' compensation for injuries | No | Separate WC policy required |
Key distinction for renovations vs. new construction: On a gut renovation or partial remodel, carriers may require the policy to cover the existing structure's full replacement cost — not just the construction budget — because fire or collapse could destroy pre-existing improvements. Always confirm how the policy schedules the existing structure.
Who Is Required to Carry Builders Risk?
Responsibility for purchasing builders risk depends on the contract structure, but the obligation almost always falls on one party:
- Property owner — most standard AIA contract forms (A101, A102) make the owner responsible for purchasing builders risk unless the contract specifies otherwise.
- General contractor — some contracts shift responsibility to the GC, particularly on design-build projects. The GC then names the owner and lender as additional insureds.
- Lender — construction lenders typically require evidence of builders risk before releasing funds. If you finance with a construction or renovation loan, proof of coverage is non-negotiable.
Subcontractors are usually covered under the same policy by contract requirement but should confirm they are listed or that the policy extends to subcontracted work.
When Does Your Existing Property Policy Stop Covering You?
This is the most dangerous misconception in renovation risk management. Commercial property policies commonly include language that:
- Voids or reduces coverage if the building is vacant or under construction for more than 30–60 consecutive days.
- Excludes damage caused by or resulting from construction activity (falling objects, fire from hot-work, water intrusion from open roofs).
- Limits the covered value to the pre-renovation value — leaving new materials and improvements uninsured.
Even if your carrier does not formally cancel, submitting a renovation-damage claim on a standard property policy invites a coverage dispute. Builders risk eliminates that ambiguity.
How Much Does Builders Risk Cost for a Renovation?
Premiums are calculated as a percentage of the total insurable value (TIV), which equals the completed project value including existing structure (if scheduled).
| Project Type | Typical Rate (% of TIV) | Example Budget | Illustrative Premium |
|---|---|---|---|
| Light commercial remodel (retail, office) | 0.5%–1.2% | $300,000 | $1,500–$3,600 |
| Mid-size commercial renovation | 1.0%–2.0% | $750,000 | $7,500–$15,000 |
| Restaurant / food-service gut renovation | 1.5%–3.0% | $500,000 | $7,500–$15,000 |
| Mixed-use / multi-family renovation | 1.0%–2.5% | $1,500,000 | $15,000–$37,500 |
| Historic or masonry structure | 2.0%–4.0% | $2,000,000 | $40,000–$80,000 |
Rates above are illustrative ranges based on industry experience and are not a quote or guarantee. Final premiums depend on location, construction type, occupancy, loss history, and selected deductible.
Factors that raise rates: Frame construction, coastal/flood zone location, phased occupancy during renovation, prior losses, project duration exceeding 12 months.
Factors that lower rates: Sprinklered building, masonry construction, short project timeline, experienced GC with low experience mod (EMR), higher deductible elected.
How to Get Builders Risk Coverage for a Renovation in 6 Steps
- Confirm contract responsibility. Read your construction contract (AIA A201 Article 11 or equivalent) to determine who purchases the policy — owner or GC.
- Calculate the total insurable value (TIV). Add the construction budget + existing structure replacement cost + soft cost endorsement amount if elected.
- Gather project data. Carriers need: project address, construction start and end dates, construction type (frame/masonry/steel), occupancy use, and GC information including EMR.
- Choose coverage options. Decide whether you need soft costs, business income delay, off-site storage, or testing and commissioning extensions before binding.
- Bind the policy before work begins — or before materials are delivered to the site. Damage to materials on-site prior to policy inception is not covered retroactively.
- Notify the carrier of any scope or schedule changes. Significant scope increases may require a mid-term endorsement to raise the coverage limit; project extensions require a term extension before expiration.
Real-World Example: Dental Office Renovation in Texas
A dental practice owner in Austin, TX contracted with a general contractor to gut-renovate a 4,000 sq. ft. commercial suite into a new clinic. Construction budget: $620,000. Existing tenant improvement value already in place: $180,000.
- TIV insured: $800,000 (construction budget + existing improvements)
- Policy term: 9 months
- Soft costs endorsement: $45,000 (re-permitting, architect re-draws if a covered loss required rebuilding)
- Annual premium: approximately $9,600 (1.2% of TIV), prorated for 9 months = ~$7,200
- Deductible elected: $5,000 per occurrence
During framing, a subcontractor's cutting torch ignited insulation, causing $38,000 in fire damage to new framing and HVAC rough-in. The builders risk policy paid $33,000 (loss minus deductible). The owner's existing property policy would have denied the claim under its hot-work and "under construction" exclusions.
This scenario is illustrative only and is not a guarantee of coverage or premium for any specific project. Coverage determinations depend on actual policy terms and the facts of any loss.
FAQ
Does my landlord's property insurance cover my renovation?
No. Commercial landlord policies cover the base building as-is. Tenant improvements and betterments during construction are your responsibility. You need either a builders risk policy or a tenant improvement (TI) endorsement on your own policy — and during active construction, builders risk is the correct vehicle.
Does the general contractor's insurance cover the building during renovation?
A GC's general liability policy covers third-party bodily injury and property damage but does not cover accidental damage to the building under construction. That is a builders risk exposure. The GC may purchase builders risk and name the owner as an additional insured, but confirm this in writing before work begins.
How long does a builders risk policy last?
Policies are typically written for the duration of the project — commonly 3, 6, 9, or 12 months — with options to extend. Coverage ends at substantial completion, occupancy, or policy expiration, whichever occurs first. Renewing or converting to a standard property policy at completion is essential; there is a coverage gap if you delay.
Can I get builders risk for a renovation I'm doing myself (owner-builder)?
Yes, but it may be harder to place. Carriers prefer licensed GCs with verifiable loss histories. Owner-builder projects often face higher rates or sub-limits. You will need to document your construction experience and may need to hire a licensed GC for certain trades to qualify with standard markets.
Does builders risk cover theft of materials from the job site?
Yes — most builders risk policies cover theft of materials that are permanently incorporated into the building or scheduled to be. However, theft of contractors' tools, equipment, and movable items is generally excluded and must be covered under a tools and equipment floater or inland marine policy.
What is the deductible on a builders risk policy?
Deductibles range from $1,000 to $25,000+ per occurrence on most commercial renovation policies. Higher deductibles meaningfully reduce premium. Some policies also carry a percentage-of-loss deductible (e.g., 2% of TIV) for wind or hail losses in coastal states.
Do I still need general liability if I have builders risk?
Yes — these are distinct coverages. Builders risk covers physical damage to the project itself. General liability covers bodily injury or property damage claims made by third parties (a visitor injured on-site, damage to an adjacent property). Both are typically required by lenders and municipalities.
What happens if my renovation runs over the policy end date?
You must request a term extension before the policy expires. Coverage does not automatically renew. If your policy lapses and a loss occurs, there is no coverage for that gap period. Build a 30-day buffer into your policy term to account for construction delays.
