Homeowner's Insurance After a Major SF Renovation

By Solid Bay Construction SF | Updated 2026

Most homeowners think about contractor insurance during a renovation, but their own homeowner's policy also needs attention — both during construction and after the work is complete.

During Construction: What Your Policy May Not Cover

• Vacant home exclusions: If you move out during a major renovation, many standard policies limit or exclude coverage after the home has been vacant for a set period (often 30-60 days) — ask your carrier whether a vacancy endorsement is needed
• Builder's risk coverage: For substantial renovations or new construction (like a ground-up ADU), a separate builder's risk policy covering the structure during construction is often more appropriate than relying on your existing homeowner's policy, which may not be designed for a home mid-construction
• Your contractor's liability doesn't replace your coverage: A contractor's general liability policy protects against claims they caused, but doesn't cover your own property against unrelated risks like fire or theft during the project

After the Renovation: What to Update

• Dwelling coverage amount: A kitchen remodel, addition, or ADU increases your home's rebuild cost — if your dwelling coverage limit isn't updated, you could be significantly underinsured in a total loss
• Updated replacement cost estimate: After a major renovation, request an updated replacement cost calculation from your carrier rather than assuming your existing limit still reflects reality
• New structures: A newly built ADU, detached garage conversion, or significant addition may need to be specifically added to your policy, not automatically assumed to be covered under the main dwelling
• Documentation: Keep your contractor's final invoices, permit final sign-off, and photos of the completed work — this documentation is valuable both for the insurance update and for any future claim

Ordinance or Law Coverage

This often-overlooked coverage type pays for the cost of bringing an older home up to current code if it needs to be substantially rebuilt after a covered loss (fire, for example). Many standard policies include only a limited amount of this coverage — often around 10% of dwelling coverage — which can be insufficient for an older San Francisco home with significant legacy conditions. After a major renovation that brought parts of your home up to current code, it's worth reviewing whether your Ordinance or Law coverage limit still makes sense.
