Home Improvement Insurance: What Homeowners Need to Know

Home improvement insurance refers to two different types of coverage. For homeowners, it means protecting your property during renovation projects through your existing policy or additional builder’s risk coverage. For contractors, it means business insurance that protects against liability claims and property damage while working on client homes.

Most homeowners don’t realize their standard policy may not fully cover renovation work. Major projects can create coverage gaps that leave you financially exposed to theft, contractor mistakes, or weather damage during construction.

What Home Improvement Insurance Actually Means

The term “home improvement insurance” confuses because it describes two separate insurance needs.

If you’re a homeowner planning a renovation, you’re looking for coverage that protects your home and building materials during construction. This typically involves your existing homeowners policy, possibly with endorsements or temporary builder’s risk insurance.

If you’re a contractor running a home improvement business, you need commercial general liability, workers’ compensation, and professional liability insurance to protect your company.

This article focuses primarily on what homeowners need to know. We’ll cover contractor insurance basics at the end.

Insurance Coverage During Your Home Renovation

Your standard homeowners policy provides some protection during renovations, but major projects create risks your policy may not cover.

When You Must Notify Your Insurance Company

You must notify your insurer before starting certain projects. Most insurance companies require notification for work that involves structural changes, additions, or projects that leave your home exposed to the elements.

Projects that typically require notification include kitchen and bathroom remodels, room additions, roof replacements, foundation work, and converting unfinished spaces like basements or attics.

Contact your insurance agent at least two weeks before work begins. This gives them time to review your coverage and recommend adjustments. If you skip this step, your insurer may deny claims related to the renovation or even cancel your policy.

What Your Standard Homeowners Policy Covers

Your existing policy covers some renovation risks. Dwelling coverage protects the structure if fire or covered perils damage your home during construction. Liability coverage protects you if someone gets injured on your property during the project.

Personal property coverage extends to building materials you’ve purchased, but only up to your policy limits. Most standard policies include coverage for materials on your premises, though some insurers cap this at 10% of your dwelling coverage.

Your policy won’t cover faulty workmanship, contractor errors, or intentional damage. It also may not cover your home if it sits vacant for extended periods during major renovations.

Coverage Gaps You Need to Know About

Several common scenarios fall outside standard homeowners coverage. If your home remains vacant for more than 30 to 60 days during renovation (timeframes vary by insurer), your policy may suspend coverage or require a vacant home endorsement.

Theft of building materials stored on-site may exceed your personal property limits. A kitchen remodel with $40,000 in cabinets and appliances on-site could leave you underinsured if your personal property coverage maxes out at $150,000 and you already have $120,000 worth of belongings.

Weather damage to exposed areas during construction creates gray areas. If contractors remove your roof and a storm damages interior spaces, coverage depends on whether the exposure was reasonable and temporary.

Damage caused by your contractor’s negligence typically falls under their insurance, not yours. But if they lack adequate coverage or dispute the claim, you could face delays or gaps in protection.

Builder’s Risk Insurance for Major Projects

Builder’s risk insurance provides specialized coverage during construction or major renovations. This policy protects your home and materials from damage, theft, and weather-related issues during the project.

Consider builder’s risk insurance for projects lasting several months, additions that significantly increase your home’s value, or renovations that leave your home partially exposed or uninhabitable.

Coverage typically includes the structure under construction, permanent materials and fixtures, temporary structures on-site, and materials stored at the location. Most policies last 60 to 90 days with options to extend.

Costs vary based on project value and location. Expect to pay roughly 1% to 4% of your renovation budget. A $100,000 kitchen remodel might cost $1,000 to $4,000 for builder’s risk coverage.

Builder’s risk insurance differs from homeowners coverage because it specifically addresses construction risks. It covers materials in transit, provides higher limits for theft, and includes coverage for work in progress that standard policies exclude.

Verifying Your Contractor’s Insurance

Your contractor’s insurance protects you from liability if their work causes damage or if someone gets hurt during the project. Always verify coverage before signing a contract.

Require contractors to carry general liability insurance with minimum coverage of $1 million per occurrence and $2 million aggregate. For larger projects or structural work, consider requiring $2 million per occurrence.

Ask for a certificate of insurance directly from their insurance company, not a photocopy. Verify the policy is current and covers the dates of your project. The certificate should name you as an additional insured or certificate holder.

Red flags include contractors who resist providing insurance information, certificates that look altered or outdated, coverage amounts that seem too low for the project scope, or policies set to expire during your renovation timeline.

Call the insurance company listed on the certificate to confirm coverage is active. This takes five minutes and protects you from fraudulent certificates.

How Renovations Affect Your Insurance After Completion

Completing a renovation changes your home’s value, which affects your insurance needs. A finished basement, kitchen remodel, or room addition increases your home’s replacement cost.

Contact your insurer within 30 days of project completion to update your dwelling coverage. Provide documentation including final project costs, receipts for materials and labor, updated square footage, and photos of completed work.

Premium increases depend on the added value. A $50,000 kitchen remodel might increase your annual premium by $100 to $300. Room additions typically have a larger impact because they increase square footage.

Some improvements actually lower premiums. New roofs, updated electrical systems, modern plumbing, and security system installations may qualify for discounts that offset the increased dwelling coverage cost.

Common Insurance Mistakes Homeowners Make

Starting work without notifying your insurer ranks as the most expensive mistake. One homeowner began a $75,000 bathroom addition without informing their insurance company. When a pipe burst during construction and caused $30,000 in water damage, the insurer denied the claim because the undisclosed construction violated policy terms.

Assuming all damage is covered creates problems during claims. Homeowners often discover too late that their contractor’s negligence isn’t covered under their own policy, or that material theft exceeded their personal property limits.

Failing to verify contractor insurance leaves you liable if workers get injured or the contractor damages your property. You become responsible for medical bills, lost wages, and repair costs if your contractor lacks proper coverage.

Not updating coverage post-renovation means you’re underinsured. If your $300,000 home is now worth $375,000 after a major kitchen and bathroom remodel, you’ll only receive $300,000 if a total loss occurs.

Skipping permits affects insurance coverage. Most policies require work to meet local building codes. If you skip permits and later file a claim, your insurer may deny it or reduce payment because the work wasn’t properly authorized.

For Home Improvement Contractors: Business Insurance Basics

If you run a home improvement business, you need commercial insurance to protect your company and meet client requirements.

General liability insurance covers third-party bodily injury and property damage claims. This protects you if you accidentally damage a client’s home or if someone gets injured at a job site.

Workers’ compensation insurance is required in most states once you hire employees. It covers medical expenses and lost wages if workers get injured on the job.

Professional liability insurance (also called errors and omissions) protects against claims that your work didn’t meet professional standards or caused financial loss to clients.

Most homeowners now require proof of insurance before signing contracts. Expect to carry minimum coverage of $1 million general liability and appropriate workers’ compensation for your state.

FAQs

Do I need special insurance for a kitchen remodel?

Not always. Your standard homeowners policy covers many kitchen remodels, but you should notify your insurer before starting work. For high-end remodels over $50,000 or projects lasting several months, consider builder’s risk insurance to cover materials and protect against theft or weather damage during construction.

What happens if my contractor damages my home?

Your contractor’s general liability insurance should cover damage they cause during work. File a claim directly with their insurance company. If they lack insurance or their coverage is inadequate, you may need to file under your own homeowners policy, though this could affect your rates. This is why verifying contractor insurance before work begins is critical.

Will my insurance premium increase after renovations?

Yes, premiums typically increase because renovations raise your home’s replacement cost. A $30,000 bathroom remodel might add $75 to $200 annually to your premium. However, certain improvements like new roofs, electrical updates, or security systems may qualify for discounts that partially offset the increase.

How much does builder’s risk insurance cost?

Builder’s risk insurance costs 1% to 4% of your total project budget. A $75,000 renovation would cost roughly $750 to $3,000 for coverage. Costs depend on project location, duration, and your home’s condition. Policies typically cover 60 to 90 days with extension options available.

Can I do DIY renovations without notifying my insurer?

Minor cosmetic work, like painting or replacing fixtures, doesn’t require notification. But DIY projects involving electrical, plumbing, structural changes, or roofing should be reported to your insurer. Even DIY work must meet local building codes and permit requirements. Unpermitted work can lead to denied claims.

What if my home is unlivable during the renovation?

Your homeowners policy’s additional living expenses (ALE) coverage typically doesn’t apply to planned renovations. ALE covers temporary housing only when a covered peril makes your home uninhabitable. For planned renovations requiring you to move out temporarily, you’ll pay those costs out of pocket. Some insurers offer optional endorsements for this scenario.

Does homeowners’ insurance cover stolen building materials?

Standard policies cover materials on your property under personal property coverage, but limits may be too low for expensive renovations. If you have $150,000 in personal property coverage and $40,000 in materials on-site, you’re at risk if theft occurs. Builder’s risk insurance provides higher limits specifically for construction materials.

When should I update my dwelling coverage amount?

Update your dwelling coverage within 30 days of completing your renovation. Your insurer needs accurate replacement cost figures to provide proper coverage. Delaying this update leaves you underinsured. If a total loss occurs before you update coverage, you’ll only receive the old dwelling limit, not enough to rebuild your improved home.
