You bought the lot, or you are gutting a property to the studs, and instead of hiring a general contractor you decided to run the job yourself. That can save real money and give you control over every decision. It also quietly moves a set of risks onto you that a homeowners policy, or a finished-building policy, was never built to carry. Here is the coverage that protects the project, and you, while it is under construction.
What “acting as your own GC” actually means
An owner-builder takes on the work a licensed general contractor would normally do: coordinating subcontractors, pulling permits, managing the schedule and the budget, and keeping the site safe and on track. That is a lot of responsibility, and with the role comes the exposure. Delays, a subcontractor who does poor work, a budget that slips, an injury on site, these are now partly yours to manage. Insurance does not remove that responsibility, but it puts a backstop under it.
Why your homeowners policy is not enough
A homeowners policy is designed for a finished, lived-in home. A construction site is a different animal: open framing, materials stacked on site, trades coming and going, and often no one living there. Most homeowners policies limit or exclude coverage while a home is under construction or sitting vacant. If a loss happens during the build and there is no construction coverage in place, you can be left paying for it yourself, which is exactly the surprise we want to avoid.
The coverage that protects a build
A few different coverages work together on a construction project:
- Builders risk, or course of construction. This is the core. It covers the structure while it is being built, plus the materials and supplies that will become part of it, against perils like fire, wind, and theft. Start with what builders risk is and who needs it, and see what it costs.
- Liability during construction. If someone is injured on your site, or a neighbor’s property is damaged, the claim can land on you as the person running the job. Premises and general liability respond to that.
- Tools, materials, and equipment. Theft of materials or damage to equipment, in transit or stored on site, can be covered, sometimes within builders risk and sometimes through inland marine. It is worth confirming, because materials theft is common on open sites.
- Flood and earthquake. Both are excluded from standard property coverage and written separately. A bare lot or a new build can still be exposed, especially in flood or seismic areas.
Your biggest hidden exposure: the subcontractors
When you act as your own GC, you are not just insuring a building. You are taking on the people you hire. If a subcontractor is unlicensed or uninsured and someone gets hurt, or their work fails, the exposure can flow back up to you, because there is no contractor’s policy standing in front of yours. This is the part owners underestimate most.
Three habits protect you: hire licensed and insured subcontractors, collect a certificate of insurance from each one before they start, and ask to be named as an additional insured where it is appropriate. Keep the paperwork. It is the cheapest risk control on the whole job.
What affects whether you can get covered, and what it costs
Owner-builder projects are evaluated on more than the building. The things that move the decision and the price include your experience managing construction, the scope and value of the build, the location and its catastrophe exposure (wildfire scoring and proximity to brush or timber matter a lot in the West), whether your subcontractors are licensed and insured, the construction timeline, and how the site is secured. Standard carriers often pass on owner-builders, so coverage frequently comes from specialty or excess and surplus markets that are built for construction risk. That is normal, not a red flag.
Before you break ground: a short checklist
Have these ready and the coverage conversation goes quickly:
- A clear project description and scope
- The construction budget and the estimated completed value
- Planned start and completion dates
- The list of subcontractors and proof of their insurance
- The property location and any catastrophe exposure
- Site-security and risk-mitigation steps you are taking
Talk to us before the first nail
The best time to sort out coverage is before work begins, not after a delivery is stolen or a storm hits open framing. We place builders risk and owner-builder coverage, and we will tell you in plain terms what protects the project, what to require from your subcontractors, and where the real gaps are. Get a quote with your project details, or compare your coverage if you already have a policy and want a second read before you build.
