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 in the event of a total loss.

Completed Operations Coverage: The Long Tail of Liability

A general contractor's liability doesn't end when the final punch list is signed. Oregon law allows for a 10-year statute of repose for construction defects, meaning a property owner can bring a claim for faulty work up to a decade after substantial completion. Completed operations coverage, which is part of a standard general liability policy, is designed to cover these long-tail claims. The key is to ensure this coverage is not sub-limited (i.e., has a lower limit than the main GL policy) and that you maintain coverage continuously even after a project is finished.

Subcontractor Insurance: Certificates, Additional Insureds & Default Risk

General contractors are responsible for verifying the insurance of their subcontractors. Best practices include:

• Collecting Certificates of Insurance (COIs): Before a sub sets foot on the job site, the GC should have a current COI on file showing active general liability and workers' compensation coverage.
• Requiring Additional Insured Status: The GC should be named as an additional insured on the subcontractor's general liability policy. This allows the GC to tender a claim directly to the sub's insurer if the sub's work causes a loss.
• Considering Subcontractor Default Insurance (SDI): For large projects with significant subcontractor costs, SDI (also known as "Subguard") can protect the GC if a key subcontractor goes out of business, defaults on their contract, or otherwise fails to perform.

Special Considerations for Owner-Builders in Oregon

If you are acting as an owner-builder on your own residential project in Oregon, you are exempt from CCB licensing for work on your own property. However, this does not exempt you from insurance realities. You will likely still need to purchase a builder's risk policy to satisfy your lender, and you are responsible for ensuring any subcontractors you hire are properly licensed and insured. If a subcontractor is uninsured and one of their employees is injured on your property, you could be held liable. Always verify CCB status and collect COIs, even for small jobs.
