Construction Insurance in Oregon: What General Contractors, Subcontractors & Owner-Builders Need to Know

Construction is one of the most insurance-intensive industries in Oregon. A single project involves multiple parties — a general contractor, a half-dozen subcontractors, a property owner, a lender, and a municipality issuing permits — each with their own exposure and their own insurance obligations. The Oregon Construction Contractors Board (CCB) sets minimum requirements, but the real-world insurance needs of a construction project go well beyond the CCB's floor. This guide covers what general contractors, subcontractors, and owner-builders need to know about construction insurance in Oregon — and how to avoid the coverage gaps that cause the most expensive claims.

Oregon CCB Insurance Requirements: The Starting Point

Every contractor licensed by the Oregon CCB must carry a minimum of $1,000,000 per occurrence in general liability insurance. This requirement applies to all license endorsements — residential general contractor, commercial general contractor, residential specialty contractor, and commercial specialty contractor. The CCB actively verifies coverage status, and a lapse can trigger an immediate license suspension that is publicly visible to property owners and project owners who check your credentials online.

Beyond general liability, Oregon law requires workers' compensation coverage for any contractor with one or more employees. Oregon's workers' comp system requires both obtaining coverage (through SAIF Corporation or a private carrier) and filing a Notice of Compliance with the Oregon Workers' Compensation Division. Failing to file the notice is a separate violation from not having coverage — and both carry penalties. Sole proprietors are exempt from mandatory workers' comp but may elect voluntary coverage.

The Full Construction Insurance Stack

The CCB's $1M GL requirement is a floor, not a ceiling. A complete construction insurance program for an Oregon general contractor typically includes the following coverages:

Builder's Risk Insurance: Who Buys It and What It Covers

Builder's risk insurance covers a structure under construction against physical damage — fire, wind, hail, vandalism, theft of materials, and certain water damage events. It is project-specific coverage that attaches when construction begins and terminates when the project reaches substantial completion. On most Oregon construction projects, either the general contractor or the property owner purchases the builder's risk policy, and the policy names both as insureds.

The policy limit should equal the full completed value of the structure, not just the cost of materials on hand. Oregon's Department of Administrative Services requires that builder's risk coverage for state-funded projects equal the full amount of the contractor's labor, equipment, materials, and fixtures to be installed. This standard is a useful benchmark for private projects as well. A policy written for less than the completed value creates a coinsurance gap that can leave the owner significantly underinsured after a major loss.

Builder's risk policies typically exclude the following: land, existing structures (covered under a separate property policy), employee theft, mechanical breakdown, and losses caused by faulty workmanship. The exclusion for faulty workmanship is important — it means builder's risk does not cover the cost of repairing defective work itself, only the resulting damage to other property. For protection against defective workmanship claims, general contractors need completed operations coverage under their GL policy.

General Contractors: Managing Risk Across the Entire Project

General contractors bear the broadest insurance obligations on any construction project. As the party responsible for the overall project, a GC faces liability exposure from their own work, from the work of every subcontractor they hire, and from conditions on the job site that affect workers, visitors, and adjacent property. A comprehensive GC insurance program addresses all three layers.

Subcontractor default is one of the most significant — and most underinsured — risks a general contractor faces. When a subcontractor fails to complete their scope of work, the GC is responsible for completing the project on time and within budget. Subcontractor default insurance (SDI) is a specialty product that covers the cost of completing a subcontractor's scope after a default. It is not widely used on smaller projects, but for GCs managing large commercial or public works projects in Central Oregon, it is worth evaluating.

GCs who perform design-build work — providing both design services and construction — need professional liability insurance (also called errors and omissions) in addition to their GL policy. Standard GL policies exclude professional services, meaning a design error that causes a construction defect may not be covered without a separate professional liability policy.

Subcontractors: What GCs Require and What You Actually Need

Subcontractors in Oregon face a two-layer insurance obligation: the CCB's minimum requirements, and the additional requirements imposed by general contractors as a condition of being awarded a subcontract. Most GCs require subcontractors to carry higher limits than the CCB minimum — $1M per occurrence and $2M aggregate is standard on commercial projects, and many GCs require subcontractors to name the GC as an additional insured on their GL policy.

The additional insured requirement is important to understand. When a GC is named as an additional insured on your GL policy, it means the GC's own GL insurer can seek reimbursement from your insurer if the GC is sued for something caused by your work. From the subcontractor's perspective, this means your policy is effectively providing coverage for the GC's liability arising from your operations. Make sure your policy includes a blanket additional insured endorsement — this automatically extends additional insured status to any party required by written contract, without needing to name each GC individually.

Owner-Builders: The Insurance Gap Most Homeowners Don't Know About

Oregon law allows property owners to act as their own general contractor — the "owner-builder" exemption — without obtaining a CCB license, provided they are building or improving their own primary residence and do not intend to sell the property within two years of completion. This exemption is commonly used by homeowners managing their own custom home construction in Central Oregon communities like Bend, Prineville, and Sisters.

The owner-builder exemption from CCB licensing does not exempt the property owner from insurance obligations. As the de facto general contractor, an owner-builder is responsible for maintaining adequate liability insurance to cover injuries to workers and visitors on the job site who are not covered by workers' compensation. Oregon's CCB Information Notice to Owners About Construction Responsibilities explicitly states that the owner's liability insurance must be sufficient to cover these exposures.

Owner-builders also face a workers' compensation exposure that surprises many homeowners. If you hire workers directly — rather than through licensed subcontractors who carry their own workers' comp — you may be considered the employer and required to provide workers' compensation coverage. Oregon's workers' comp rules apply broadly, and misclassifying workers as independent contractors is a common and costly mistake. Before hiring any worker directly on an owner-builder project, consult with an insurance agent and an attorney familiar with Oregon construction law.

Completed Operations: The Coverage That Protects You After the Job Is Done

Completed operations coverage is the portion of your general liability policy that covers claims arising from your work after the project is finished. For construction contractors, this is one of the most important — and most frequently misunderstood — coverages in their program. A construction defect claim, a structural failure, or a water intrusion problem traced back to your work can surface years after project completion, and without completed operations coverage, your GL policy may not respond.

Oregon's construction defect liability laws provide a 10-year statute of repose — no claims can be made more than 10 years after substantial completion of the construction, regardless of when the defect was discovered. This means your completed operations coverage needs to remain in force for up to 10 years after a project is completed to provide full protection. Many contractors purchase an extended reporting period endorsement (also called a tail) when they retire or wind down their business to maintain completed operations coverage for the statutory period.

The Oregon Supreme Court's 2025 decision in Twigg v. Admiral Insurance expanded CGL coverage for construction defects, confirming that unintended property damage from negligent work may qualify as a covered "occurrence" under a standard GL policy. This is a favorable development for Oregon contractors, but it does not eliminate the need for adequate completed operations limits — the question of whether a claim is covered is separate from whether your limits are sufficient to pay it.
