How to Review Home Insurance After a Renovation

Quick answer

After a renovation, contact your home insurance provider to reassess your dwelling coverage limit. Renovations can increase your home's replacement cost, add new risks (like a swimming pool or home office), or qualify you for discounts. Even smaller projects, such as a new roof or upgraded electrical, may affect premiums. Review your policy's dwelling, other structures, personal property, and liability coverages, and ask about any required endorsements. Do this before the project starts to ensure coverage during construction and immediately after completion to lock in proper protection.

Who should use this guide

If you've recently completed a renovation, are planning one, or are in the middle of a project, this guide helps you align your home insurance with your updated property. It's especially relevant for homeowners who have added square footage, upgraded major systems, built an accessory dwelling unit (ADU), installed a pool or trampoline, or converted a space into a home-based business. Renters who have made improvements with landlord permission may also need to revisit their renters insurance.

• Homeowners finishing a kitchen, bathroom, or basement remodel
• Anyone who has added an extension, ADU, or finished attic
• Owners who installed a pool, hot tub, or other attractive nuisance
• Those who upgraded electrical, plumbing, or roofing systems
• Policyholders unsure if their current limit matches their home's new value

What to check first

Start by obtaining an updated estimate of your home's replacement cost. This isn't the market value or the amount you spent on the renovation-it's the cost to rebuild your home from scratch at current labor and material prices. Your insurer or a professional appraiser can help. Compare this figure to the dwelling coverage (Coverage A) on your declarations page. If the new replacement cost exceeds your limit, you're underinsured and may face a coinsurance penalty at claim time. Also verify that other coverages-such as other structures (Coverage B), personal property (Coverage C), and loss of use (Coverage D)-are adequate relative to your new overall dwelling limit.

• Obtain a current replacement cost estimate from a builder, appraiser, or insurer's tool
• Compare the estimate to your dwelling coverage limit (Coverage A)
• Check if your policy includes an inflation guard or extended replacement cost endorsement
• Review Coverage B (other structures) if you added a detached garage or shed
• Ensure liability limits (Coverage E) address new risks like a pool or trampoline
• Confirm that your personal property coverage is enough if you purchased new furnishings or appliances

Action steps

Notify your insurer or agent as soon as you plan a renovation. Some policies require you to inform them of substantial changes. During construction, verify that your policy covers materials on-site and any liability for contractors or injuries. Once the project is complete, provide documentation-such as final costs, photos, and permits-so the insurer can adjust your coverage accurately. If the renovation improved your home's resilience (e.g., new impact-resistant roof or upgraded electrical), ask about potential discounts. Consider increasing your liability coverage if you've added features that raise the risk of injury to others.

• Contact your insurance company or agent before starting any major renovation
• Ask about a builder's risk or course of construction endorsement if needed
• Keep records of all renovation expenses, permits, and contractor agreements
• Request a policy review after completion and provide updated information
• Ask about discounts for new safety features (roof, wiring, plumbing, security systems)
• Evaluate if you need a personal umbrella policy for added liability protection
• Update your home inventory to include new fixtures, appliances, and materials

Common mistakes to avoid

Many homeowners assume their policy automatically covers any renovation, but standard homeowners forms often exclude construction-related risks. Another error is insuring for the amount spent on the renovation rather than the full replacement cost of the entire home. Failing to update liability coverage after adding a pool or trampoline can expose you to lawsuits. Also, not inquiring about discounts for new, safer features leaves money on the table. Skipping a thorough review because you fear a premium increase can backfire if a claim is denied or underpaid.

• Assuming the renovation is automatically covered without notifying the insurer
• Insuring only the renovation cost, not the full replacement cost of the improved home
• Neglecting to increase liability limits after adding attractive nuisances
• Overlooking available discounts for updated roofs, electrical, or security systems
• Avoiding the insurer out of fear of a premium increase, risking underinsurance
• Not updating your home inventory and receipts for new additions

Questions to ask before buying

When discussing your renovation with an insurance professional, be sure to ask the right questions. Your goal is to ensure that the updated policy covers your home completely and at a competitive price, without gaps. Always verify the insurer's licensing and complaint history through your state insurance department or the NAIC Consumer Insurance Search before finalizing changes. Here are key questions to raise:

• What is the new recommended dwelling coverage limit based on my renovation?
• Does my policy include extended replacement cost, and by what percentage?
• Are there any exclusions or limitations for the specific type of renovation I did?
• What endorsements do I need for a new home office, ADU, or business use?
• Did I qualify for any discounts due to the updates?
• Should I increase my deductible to offset a premium rise, and what are the trade-offs?
• How will the renovation affect my policy's liability coverage and umbrella options?
