The construction insurance news today builders risk market looks different than it did 18 months ago. Carriers have rewritten underwriting guidelines, added new exclusions, and shifted pricing in response to $92 billion in U.S. insured catastrophe losses during 2024 and 2025 combined. General contractors who priced their 2026 projects using 2024 insurance assumptions are already discovering budget shortfalls.

This checklist covers every market change affecting builders risk in 2026 and what you need to do about each one.

2026 Builders Risk Rate Trends

Builders risk rates have moved in two directions depending on geography and construction type.

Segment	2024 Rate Range	2026 Rate Range	Change
Inland wood frame (low-risk)	$0.15-$0.25 per $100	$0.18-$0.28 per $100	+10-15%
Inland non-combustible	$0.10-$0.18 per $100	$0.12-$0.20 per $100	+8-12%
Coastal (wind-exposed)	$0.35-$0.65 per $100	$0.45-$0.85 per $100	+25-35%
Wildfire zones (CA, CO, OR)	$0.30-$0.55 per $100	$0.50-$1.00 per $100	+50-80%
High-rise wood frame (5+)	$0.25-$0.40 per $100	$0.35-$0.60 per $100	+35-50%

The biggest rate increases target wood-frame construction in wildfire and coastal zones. Carriers lost heavily on wood-frame projects during recent hurricane and wildfire seasons. A five-story wood-frame multifamily project in a California wildfire zone that cost $6,000 to insure in 2024 may now cost $10,000-$15,000.

Checklist item 1: Re-quote every builders risk policy placed before January 2026. Compare your budgeted insurance cost to current market pricing. Adjust project budgets and bids to reflect actual 2026 rates.

Carrier Capacity Changes

Several carriers reduced their builders risk capacity or exited specific segments in late 2025 and early 2026.

What changed:

Two major admitted carriers stopped writing coastal builders risk in Florida, Louisiana, and Mississippi
Three carriers imposed $10 million maximum limits on wood-frame projects (previously $25 million)
Excess and surplus (E&S) lines now handle 40-50% of coastal builders risk placements, up from 25% in 2023
Reinsurance treaty renewals in January 2026 pushed up carrier costs by 8-15%, which carriers passed through to policyholders

What this means for GCs:

Fewer carriers writing builders risk means less competition, higher rates, and longer placement timelines. Projects that received 4-5 quotes in 2023 now receive 2-3 quotes.

Checklist item 2: Start the builders risk procurement process 45-60 days before construction start, up from the previous 30-day standard. Give your broker enough time to access the shrinking market.

Checklist item 3: If your project is in a coastal or wildfire zone, confirm your broker has E&S market access. Admitted carriers may decline your risk entirely.

New Exclusions Being Added to Policies

Carriers have introduced several new exclusions or narrowed existing coverage in 2026 builders risk forms.

Climate-Related Exclusions

Wildfire exclusion zones: Carriers in California, Colorado, Oregon, and Washington now apply wildfire exclusion zones based on CAL FIRE or state-equivalent fire hazard severity maps. Projects in Very High Fire Hazard Severity Zones may face:

Mandatory 5% wildfire deductibles (percentage of coverage limit)
Sublimited wildfire coverage ($500,000-$1,000,000 caps on otherwise higher limits)
Complete wildfire exclusion (requiring separate wildfire-only coverage)

Named storm deductibles expanding: Previously limited to Florida and the Gulf Coast, percentage-based named storm deductibles now apply in the Carolinas, Virginia, and parts of the Mid-Atlantic. Typical named storm deductibles run 2-5% of the policy limit.

Checklist item 4: Review every builders risk policy for percentage-based deductibles tied to specific perils (wind, hail, wildfire, named storm). Calculate the dollar exposure. A 3% named storm deductible on a $10 million project means $300,000 out of pocket before insurance responds.

Construction Type Restrictions

Mass timber exclusions: Several carriers now exclude or sublimit mass timber (CLT, glulam) construction. The concern is fire during construction before sprinkler systems are operational. If your project uses mass timber, expect carrier scrutiny of fire prevention plans and potentially a required hot work monitoring program.

Modular/prefab coverage gaps: Carriers are clarifying (and often restricting) coverage for modular components manufactured off-site. The gap exists between the manufacturer's property insurance, the transit policy, and the builders risk policy. Some policies now explicitly exclude factory-manufactured components until they arrive on site and installation begins.

Checklist item 5: If your project involves mass timber or modular construction, disclose this to your broker at the earliest stage. Carrier underwriting requirements for these construction types now include fire watch protocols, hot work permits, and sometimes mandatory fire suppression during construction.

New Endorsement Requirements

Several endorsements that were optional in previous years are becoming mandatory in 2026, either by carrier requirement or by owner/lender demand.

Endorsement	Status in 2026	Who Is Requiring It
Green building coverage	Increasingly required	LEED/WELL-certified project owners
Cyber event exclusion	Standard on most new policies	Carriers (protects against cyber-triggered losses)
Communicable disease exclusion	Now standard	Carriers (post-COVID clarity)
Professional fees extension	Lender requirement growing	Construction lenders
Debris removal upgrade ($250K+)	Lender requirement	Lenders on projects over $5M
Pollutant cleanup	Required in brownfield areas	Environmental regulators

Green building endorsement: If a LEED-certified project suffers a loss, rebuilding to LEED standards costs 5-15% more than conventional construction. Without this endorsement, the carrier pays only for conventional rebuilding. The endorsement covers the incremental cost of green materials and certification re-filing.

Checklist item 6: Request a list of all exclusions and endorsements on your policy. Compare them against the requirements in your construction contract and your lender's insurance requirements. Flag any gaps before construction starts.

Compliance Checklist for 2026

Use this checklist on every project starting in 2026:

Pre-Construction (45-60 Days Before Start)

Identify who purchases builders risk (contract review)
Calculate the full completed value including soft costs
Submit builders risk application to broker with project details
Request quotes from at least 3 carriers (if available in your market)
Verify additional insured status for GC and all subs
Review all exclusions, especially climate-related
Calculate dollar exposure on percentage-based deductibles
Confirm waiver of subrogation endorsement
Verify policy term extends 90 days beyond planned completion

During Construction (Monthly)

Track policy expiration against current project schedule
Report change orders that increase project value beyond policy limit
Verify subcontractor certificates remain current
Document project progress with dated photographs
Update value reports (if using reporting form policy)
Monitor weather forecasts for covered peril events
Confirm temporary site security measures are in place

At Project Completion

Notify carrier of substantial completion date
Confirm owner's permanent property policy is in effect
Verify punch list coverage window (30-90 days)
Request final audit and premium adjustment
Retain loss runs for future policy renewals

If a Loss Occurs

Report to carrier within 24 hours
Protect property from further damage
Photograph all damage before cleanup
File police report for theft/vandalism
Begin compiling pre-loss documentation
Submit proof of loss within policy deadline (60-90 days)

Market Forecast: What to Expect Through Year-End 2026

Insurance industry analysts project these trends through the remainder of 2026:

Rates: Expect continued increases of 5-15% on renewals for standard risks. Coastal and wildfire exposures may see 20-40% increases if the 2026 hurricane or fire season produces significant losses.

Capacity: No new major carriers have entered the builders risk market in 2026. Capacity constraints will persist, especially for wood-frame projects over $10 million and any project in a CAT-exposed geography.

Technology impact: Carriers are increasingly using satellite imagery, IoT sensors, and AI-driven risk models to underwrite builders risk. Projects with on-site monitoring (water sensors, fire detection, security cameras) may receive 5-10% premium credits.

Checklist item 7: Discuss on-site monitoring technology with your broker. Installing water leak sensors, temperature monitors, and security cameras costs $2,000-$5,000 per project but can generate premium savings of $1,000-$3,000 while also preventing losses.

FAQs

Are builders risk rates expected to decrease in 2027? Only if 2026 produces a below-average catastrophe year. Carriers base rate decisions on loss experience over a 3-5 year window. The heavy losses from 2023-2025 will continue influencing rates regardless of 2026 results. The most likely scenario is rate stabilization (flat to +5%) for standard risks and continued increases for CAT-exposed projects.

How do I budget for builders risk when rates are changing? Add a 15-20% insurance cost contingency to your project budget. If you bid a project 6 months before construction starts, the rate you quoted may not be available at placement time. Include an insurance escalation clause in your contract that allows you to pass through actual insurance costs to the owner rather than absorbing a fixed amount.

Do I need to change my subcontractor insurance requirements because of market changes? Review your subcontract insurance requirements annually. If your project-wide builders risk policy covers all subcontractors, you may not need to change sub requirements. But if subs carry their own builders risk on specific scopes, verify that they can actually obtain coverage in the current market. Some subs in wildfire or coastal zones are struggling to find affordable builders risk.

What is a cyber event exclusion on a builders risk policy? This exclusion removes coverage for physical damage caused by cyberattacks. If a hacker takes control of a building automation system during construction and causes a water release that floods the building, the cyber exclusion may apply. This is a relatively new exclusion (widespread since 2024) that carriers added in response to growing cyber threats. If your project has significant building automation or IoT components, discuss cyber liability coverage with your broker as a separate policy.

How do E&S (Excess and Surplus) lines carriers differ from admitted carriers for builders risk? E&S carriers are not backed by state guarantee funds, meaning if the carrier becomes insolvent, the state will not pay your claim. However, E&S carriers can offer coverage that admitted carriers refuse to write, and they can price and structure policies more flexibly. In the 2026 market, E&S carriers write approximately 40-50% of coastal builders risk. Verify the financial strength of any E&S carrier (A.M. Best rating of A- or higher) before binding coverage.

Should I consider parametric builders risk policies? Parametric policies pay a fixed amount when a measurable event occurs (wind speed exceeding 100 mph, earthquake magnitude above 6.0) regardless of actual damage. They pay faster than traditional policies because there is no claims adjustment process. However, the payout may not match your actual loss. Parametric builders risk is best used as a supplement to traditional coverage, filling gaps like high deductibles or excluded perils. The market for parametric construction insurance is small but growing, with premiums running 30-50% less than equivalent traditional coverage.
