Home renovations can breathe new life into your property, increasing its value and enjoyment. However, before diving into that next big project, consider how these changes might impact your homeowner’s insurance premiums.

Some renovations increase your insurance premiums, while others may help lower your rates. This article explores how renovations can affect your homeowner’s insurance policies and which factors you should consider.

Square Footage Additions

When a renovation project increases your home’s square footage, you should immediately update the insurance policy. Adding space to a home raises the cost of rebuilding, which is a key factor in determining insurance coverage and rates.

Impact on Rebuild Costs

Expanding your home’s living area directly affects its replacement value. Insurance policies aim to cover the cost of rebuilding the entire structure in case of a total loss. As such, any addition that increases your square footage will probably mean higher premiums for the additional coverage.

Updating Your Policy

After completing a square footage addition, update your policy by:

  • Accurately measuring and documenting the new square footage
  • Informing your insurance agent of the changes
  • Requesting a comprehensive review of your existing coverage limits
  • Discussing potential impacts on dwelling and liability coverage

Proactively communicating with your insurer can help you obtain appropriate coverage and avoid being underinsured after you complete the project.

Customization and Unique Structures

Custom additions and unique structures can significantly enhance your property’s value and functionality. You must still adjust your insurance policy to accommodate these changes, which can cost you more.

Mother-In-Law Units and Exterior Decks

Adding structures like mother-in-law units or expansive exterior decks necessitates changing both dwelling coverage and liability limits. These additions do increase the property’s overall value, but they may also introduce new risks that your insurance carrier will want to account for.

Communicating with Your Insurer

Before beginning construction on customized additions, homeowners should:

  • Notify their insurance agent about planned changes
  • Provide details such as square footage, materials, and intended use
  • Request an accurate valuation for insurance purposes

By keeping the insurance company informed, homeowners can make sure their policy accurately reflects their property’s new value and risk profile.

High-End Building Materials

If you use luxury building materials for renovations, your insurance premiums may increase. Better materials may enhance your home’s aesthetic and durability, but they also increase repair and rebuilding expenses for covered losses.

Premium Materials and Replacement Costs

Luxury building materials increase the repair or rebuild cost of a covered loss. For example, high-quality building materials like porcelain tile cost more than standard materials and can raise replacement value.

Documenting Upgrades

Keep detailed receipts for all your high-end materials to ensure proper coverage and reimbursement. Document the installation process as you go with photos or videos, and provide this information to the insurance provider for accurate valuation. Investing in higher-quality materials can boost your property’s long-term value and comfort, but you should update your insurance policy to cover the upgrades.

Personal Property Coverage

Your renovations may involve adding new household items, like appliances and furniture. Such additions can impact your personal property coverage.

Assessing New Possessions

When renovating, take stock of any new items you add to the home. Expensive appliances, fixtures, and furniture contribute to an increased personal property value, which means higher replacement costs. Insurance companies typically offset this risk with higher premiums.

Replacement Cost Vs. Actual Cash Value

Review coverage options with an insurance agent when you update your items. You may select from replacement cost coverage or actual cash value coverage. Replacement cost coverage reimburses the full amount to replace your items, while actual cash value coverage pays the depreciated value of those items.

Replacement cost coverage is often the better choice for costly upgrades despite potentially higher premiums. It fully replaces your valuable items in case of loss or damage.

Liability Considerations

Certain home improvements can increase liability risks and necessitate updates to your homeowner’s insurance coverage.

High-Risk Additions

Upgrades like pools, hot tubs, or trampolines are high-risk additions because they introduce new liability concerns. They may attract visitors, including neighborhood children, which may increase the risk of accidents on the property. Liability coverage premiums will likely rise to reflect that risk.

Increasing Liability Protection

When adding features that could increase liability, first meet with your insurer to review current liability limits. Discuss the risks associated with your new additions, and determine whether the addition would be cost-effective after the insurance hike. 

Depending on your coverage, you may benefit from purchasing an umbrella policy for additional protection. An umbrella policy provides extra protection beyond the limits of a standard homeowners policy in case of a lawsuit.

Roofing Upgrades

Installing a new roof can positively impact insurance premiums by reducing weather-related issues like water damage.

Damage-Resistant Materials

Before you begin, consult with roofing professionals about damage-resistant materials. Some materials, like metal, tile, or fiberglass shingles, often withstand damage better than traditional asphalt shingles. With greater overhead protection on your home, your insurer may be willing to cover your home at a lower rate.

Insurance Discounts

Many insurers offer discounts for roofs made with impact-resistant materials. To maximize potential savings, thoroughly document the new roof installation and notify your insurance company about the upgrade.

Don’t hesitate to inquire about available discounts for impact-resistant roofing. A new, high-quality roof protects your home and can lead to lower insurance premiums.

Plumbing and Electrical System Updates

Modernizing your home’s plumbing and electrical systems can reduce the risk of water damage and fires, leading to lower insurance premiums.

Risk Reduction

Old plumbing and outdated electrical wiring are common causes of home insurance claims. Updating these systems reduces the likelihood of leaks and water damage and minimizes the risk of electrical fires, improving home safety.

Documenting Improvements

Keep detailed records of the materials and installation to benefit from lower premiums after a plumbing or electrical upgrade. Have a professional inspect and document your upgrades and provide the inspection documents when you inform your insurance company of the improvements.

Safety-enhancing renovations to plumbing and electrical systems can keep you safe while providing potential insurance savings.

Balancing Renovations and Insurance Costs

While some renovations may increase insurance premiums, the benefits often outweigh the costs. Assess the long-term value and enjoyment these improvements bring to your living space when deciding whether to renovate.

Focus on Safety Improvements

Prioritizing renovations that enhance home safety, such as updating electrical systems or installing a new roof, can sometimes qualify for insurance discounts. These upgrades can help offset premium increases from other renovations.

Communicate with Your Insurer

Throughout the renovation process, maintain open communication with the insurance company. Always discuss planned renovations before starting the project, and provide regular updates as work progresses. Immediately after you complete renovations, review coverage needs.

By working closely with your insurance agent throughout the renovation project, you can balance insurance coverage costs with improved property value and enjoyment.

Additional Considerations for Home Renovations

Renovating a home is a multifaceted venture requiring careful attention to insurance coverage and premiums. In addition to the above factors, local building codes and market trends may influence your insurance policy. 

Impact of Building Codes and Regulations

Local building codes and regulations can greatly affect your renovation project. These codes can limit your materials and construction methods, affecting your insurer’s risk assessments. For instance, if you adhere to modern safety codes, it can lead to lower risks, which reduces your insurance premiums.

Effects of Market Trends on Renovation Costs

Market trends often dictate the cost of renovation materials and labor. A surge in demand for certain styles or materials can inflate costs. Stay apprised of these trends when planning your project, as they can impact your budget and insurance coverage limits.

Ensuring Adequate Coverage During Renovation

During a renovation, your home may be at greater risk of exposure to the elements or structural vulnerabilities. Safeguard against these risks by reviewing and adjusting your homeowner’s insurance coverage during the renovation phase.

Builder’s Risk Insurance

Builder’s risk insurance is property insurance designed to protect homes under construction or renovation. This policy typically covers the building, materials, and equipment. Consider investing in builder’s risk insurance for peace of mind during renovation.

Temporary Dwelling Coverage

If you must temporarily relocate during renovations, verify whether you can obtain temporary dwelling coverage within your current policy. This type of policy covers additional living expenses if your home becomes uninhabitable during renovations.

FAQs About Home Renovation Insurance

What is a typical increase in insurance rates from renovations?

The increase depends on the specifics of your project. Simple kitchen or bathroom updates may only cause a minimal rise in your premiums. A major addition could increase rates more. Reach out to your insurance agent for quotes tailored to your specific renovation plans.


When is the best time to notify my insurer about renovations?

Alert your insurance company about renovations before major construction work begins. Provide your agent with relevant details and projected timelines for the renovation. Purchase adequate coverage as soon as the project begins.


What records should I keep about renovations for insurance purposes?

Maintain all receipts for renovation materials and costs, including items like luxury flooring and fixtures. Take photos or videos of the project. Keep detailed documentation of all upgrades.


Can renovations qualify my home for insurance discounts?

Yes, some upgrades like impact-resistant roofing, updating older plumbing or electrical systems, or adding storm shutters may qualify you for premium discounts. Check with your agent about what kinds of renovations in your area qualify for premium reductions.


How should I insure expensive new possessions added during renovations?

Think carefully about whether replacement cost or actual cash value coverage makes more sense for upgrades like high-end appliances, custom cabinets, or luxury furniture. Replacement cost coverage pays the full amount to replace items if they are damaged. Actual cash value pays the depreciated value. We recommend replacement cost coverage for very costly upgrades despite the higher premiums.
