Builder's risk insurance for Washington — coverage during the most exposed phase of any construction project
Course-of-construction property coverage that GL and homeowners policies do not include.
5 WA carriers writing builder's risk today — Vacant Express, Blitz, Pathpoint, Green Shield, and Foremost. Niche depth most agencies skip because builder's risk overlaps with vacant property, and most agents punt both. We own this lane.

The construction phase has exposures no other property policy covers
Builder's risk — also called Course of Construction — is the property coverage that protects a structure during the construction phase. Standard homeowners policies typically don't respond to losses on a building under active construction; commercial property policies typically exclude buildings that are being substantially renovated or expanded; GL covers liability but not the structure itself. The dedicated builder's risk product fills the gap with coverage for fire, theft, vandalism, weather damage, water damage, materials in transit, and the structure itself during the most exposed phase of its life.
The exposure profile during construction is materially different from a finished structure. A half-framed house with no walls is vulnerable to wind, rain, and theft in ways a completed home is not. A commercial shell with no fire-protection systems active yet has different fire exposure than the finished building. Materials staged on-site — lumber, copper, finish goods — are theft targets in a way installed materials are not. Builder's risk pricing reflects this elevated risk window, which is why it is project-specific rather than annual: it covers the construction window only, then ends.
For WA construction specifically, three additional considerations: weather risk (wind and water damage during the rainy months is real, especially in Puget Sound and coastal corridors), theft from the increasingly active material-theft pattern around metropolitan construction sites, and the regulatory complexity of getting a project from permit to certificate of occupancy without coverage gaps that lenders will flag. We walk through all three at quote time.
Six coverage layers WA construction projects need
New Construction (Single-Family)
Ground-up residential builds — single-family homes, accessory dwelling units, custom builds. Default 12-month policy term; longer available for complex projects. Covers the structure during the entire construction window through certificate of occupancy.
Renovation / Remodel
Existing structure with active construction work. Different underwriting than new construction because the existing structure has its own value and risk profile. Common for additions, kitchen and bath remodels, and ADU conversions.
Commercial New Construction
Ground-up commercial projects — retail, office, industrial, multifamily over 4 units. Project-specific underwriting based on construction type, schedule, materials, and fire-protection systems. Higher limits and longer terms standard.
Materials in Transit
Coverage for materials from supplier to job site — lumber, fixtures, equipment in delivery. Sub-limited but typically adequate for residential and small commercial projects. Higher limits available for projects with significant in-transit material flow.
Theft of Materials and Tools
Materials and tools staged on-site, vulnerable to theft during off-hours. Sub-limits typically $5K–$25K per occurrence; security requirements may apply. Critical for high-value-material projects (copper, premium lumber, finish materials).
Soft Costs
Additional financing, permits, professional fees, and other soft costs incurred if a covered loss extends the project timeline. Optional layer worth considering for highly-financed projects where carrying-cost exposure is a material concern.
The 5 WA-licensed builder's risk carriers we shop
Five carriers write WA builder's risk with real depth. The lane is unusually competitive for a niche product because builder's risk overlaps with vacant property and most agencies skip both — leaving the well-positioned agencies with strong shopping power.
- Vacant Express — Specialty carrier for residential and commercial properties that are vacant, in renovation, or new construction. Writes WA Builders Risk, Vacant Property, Vacant Commercial, and Special Event Coverage. First-call carrier for any builder's-risk inquiry — broad appetite, project-specific underwriting, and strong overlap with our vacant-property book.
- Blitz — Tech-driven E&S platform with paper backed by AM Best A-rated carriers. Quote in 5 min, bind in 10. 80% of risks bypass UW review. Writes WA Builders Risk, Commercial GL, Commercial Property, and Vacant Commercial. Right route for fast bind on residential builder's-risk and small commercial projects.
- Pathpoint — Digital E&S wholesaler with paper from Markel, Westchester, Nautilus, Crum & Forster. Writes WA Property, GL, BOP, and Middle Market Commercial Lines via E&S — builder's risk is implied via the Property and Middle Market lines. Right route for non-standard projects, complex commercial, or projects with adverse loss history.
- Green Shield Risk — MGA specializing in HNW homeowners and wildfire-exposed regions. Writes WA Builders Risk, Difference In Condition, Dwelling Fire, Landlord, and Vacant Property. Builders Risk is split into Builder's Renovation and Course of Construction sub-products with 12% commission tier. Right route for wildfire-exposed projects in Eastern WA.
- Foremost — Niche personal lines specialist since 1952. Writes WA Vacant Property and the Builders Risk card chip on the First Connect appointment. Right route for residential builder's risk on properties already in the Foremost personal-lines ecosystem (vacant, mobile home, landlord).
What WA builder's risk actually costs per project
Real 2026 ranges for clean WA projects with standard security and weather controls. Pricing assumes 12-month policy term and standard sub-limits.
- Residential new construction $250K–$500K project value: $300–$700 per project for 12-month term.
- Residential new construction $500K–$1M project value: $700–$1,500 per project.
- Renovation/remodel $100K–$500K project value: $400–$1,200 per project depending on existing structure and scope.
- Commercial new construction $1M–$5M project value: $1,500–$8,000 per project depending on construction type and fire-protection systems.
- Soft Costs endorsement: +10–20% of base premium for highly-financed projects where carrying costs matter.
Subject to underwriting approval. Drivers of variance: project value, construction type (frame, masonry, fire-resistive), site security, project duration, weather risk, and prior loss history.
What changes the builder's risk quote in Washington specifically
Washington builder's risk underwriting picks up two specific seasonal wrinkles. First, the rainy-season exposure (October through May in most of WA, longer in coastal corridors) materially affects water-damage claim frequency. Carriers will typically ask whether the project will go through a wet-season window without a watertight envelope and may price up or attach exclusions accordingly. The honest underwriting move on rainy-season-exposed projects is to disclose the schedule and let the carrier price the risk — attempting to bind on a clean-weather assumption that doesn't match reality is the path to a denied claim.
Second, wildfire season (typically August through October in Eastern WA) is a real risk for projects in fire-exposed corridors. Green Shield Risk specifically writes wildfire-exposed dwelling and builders-risk in WA — that is their lane. Vacant Express and Pathpoint also write fire-exposed projects but underwrite them more conservatively. For Eastern WA projects (Spokane, Tri-Cities, Yakima, Wenatchee), we route to Green Shield first for fire-exposed builds. The Puget Sound corridor doesn't face wildfire exposure but does face more moisture-driven losses, so the carrier routing flips depending on geography.
Builder's risk questions we hear most
It depends on the contract, and getting it wrong is the single most common builder's-risk mistake. On most owner-occupied new construction, the property owner buys builder's risk because they hold the financial interest in the building during construction. On most contractor-built spec or commercial projects, the GC buys it because the contract requires the GC to deliver a finished, undamaged structure regardless of mid-construction events. On renovation and remodel projects with the owner staying on-site, it gets messier — sometimes the owner's homeowners policy extends coverage during minor renovations, sometimes a separate builder's risk is required, and the contract typically dictates. The clean rule: read the construction contract first, identify who has the financial interest at risk during construction, and place the policy in their name with the other party named as additional insured. We walk through this on every quote.
Theft of materials and tools on the job site is a covered loss under most builder's risk policies, with sub-limits that vary materially by carrier. Standard sub-limits run $5K–$25K per occurrence for materials with a deductible typically $1K–$2.5K. The catch: many policies require certain security controls (fenced site, locked storage, after-hours lighting) before paying claims. For high-value-material projects (copper, lumber during shortage cycles, high-end finish materials staged on-site), specifically asking about the materials-theft sub-limit and security requirements at quote time prevents an unpleasant surprise at claim time. Vacant Express, Blitz, and Pathpoint all write WA builder's risk with materials-theft included; sub-limits and security requirements vary, so we shop them to find the right fit for the project profile.
No — and this is a critical and frequently misunderstood gap. Standard CGL covers third-party liability arising from your operations: a worker injured at the site, a passerby hit by falling debris, damage to a neighboring property. CGL does not cover damage to the structure you are building. The structure itself, plus the materials staged on-site, plus tools and equipment, fall under builder's risk — a separate policy. A fire that destroys a half-built house mid-project is a builder's-risk claim, not a GL claim. We bundle GL and builder's risk for every contractor account that has active construction projects, because either alone leaves the gap that real claims fall through.
Real 2026 ranges for clean WA projects with standard security and weather controls: residential builder's risk typically runs $300–$1,500 per project for a 12-month policy on a $250K–$1M project value — with the variance driven by project type (new construction vs renovation), site security, and frame type. Commercial builder's risk for $1M–$5M project value typically runs $1,500–$8,000 per project depending on construction type, fire-protection systems, and project duration. Larger commercial projects price project-specifically based on the schedule, materials, sub-contractor scope, and any Soft Costs coverage layered on. Subject to underwriting approval. Drivers of variance: project value, construction type (frame, masonry, fire-resistive), site security, project duration, and prior loss history.
Most builder's-risk policies are written for a specific project term (typically 6, 9, or 12 months) with a defined completion date. If the project runs long, you need to extend the policy before it expires — uncovered weeks during the most exposed phase of construction is a real risk most contractors underestimate. Most carriers will extend with a pro-rated premium adjustment if requested before expiration. Letting the policy lapse and trying to bind retroactively is much harder, often impossible — once the carrier knows the project ran long, they may decline the extension or attach exclusions. For projects with material schedule risk (weather-sensitive coastal work, projects subject to regulatory delays, complex commercial work), Pathpoint and Vacant Express both write longer initial terms or extension-friendly policies. We screen for schedule risk on every builder's-risk quote.
