Homeowners might choose to renovate to create more living space, update their home’s design or even put in a pool. Whatever the reason, homeowners may want to consider if their renovations could impact their home insurance policy. Some renovations may prompt you to adjust your coverage types or limits, while others may actually save you money on your insurance premium. Bankrate’s insurance editorial team explores how seven popular home renovations may impact your home insurance rates.

Renovations that increase home insurance rates

A home renovation may increase the value of your home, but it can also drive up the cost of your home insurance. In addition to the expense of the renovation, you may see higher premiums if your renovation pushes you to increase your coverage limits or exposes you to greater liability.

Building a swimming pool: In certain locations, adding a pool to your home can increase its value and offer an incentive to would-be buyers. However, a swimming pool is considered an “attractive nuisance” and significantly increases your liability risk, which will likely increase your homeowners insurance premium.

A standard homeowners insurance policy usually includes liability coverage, which is designed to help cover medical costs for a person injured on your property and legal expenses if you are sued. However, an insurance agent may recommend that a pool owner opts for higher liability coverage than what is standard. Homeowners might also consider purchasing an umbrella insurance policy, which provides additional liability coverage for greater financial protection if a covered claim exceeds the homeowners liability coverage amount.

Adding an office for a home business: Working remotely has become more common, so adding an office could increase your home’s value if you are a remote worker or home-based business owner. However, it could also increase your homeowners insurance rates or require you to purchase an endorsement to increase coverage for business-related assets and equipment, or a separate home business policy that provides protection against crime and worker injuries.

Most homeowners policies protect equipment for home-based businesses up to about $2,500, though you may be able to increase this amount, depending on the company. That might not be enough for a business owner who uses specialized machinery or stores large amounts of supplies or inventory at their home.

Some carriers may include a home insurance exclusion for business use of personal property in your home, so be sure to talk to your agent if you have work-use items in your home and make sure you have the right level of coverage. Additionally, homeowners insurance companies might not cover liability related to the business.

Building on an extension: Sometimes a home needs to be changed to accommodate an expanding family. That can mean modifying a floor plan and adding more livable square footage, like finishing a basement or attic. In other instances, a new addition may be in order. Expanding your space with new square footage will most likely increase your home insurance premium as you will need a higher level of dwelling coverage.

You might need more post-renovation insurance even if the added space is not inside your house. Adding a large finished deck could increase the value of your home, for example, and consequently, require an insurance reassessment. You may also need to consider other types of coverage for the newly built areas of your home. For example, a finished basement with new carpet, drywall and insulation may need sewer backup coverage.

Upgrading your kitchen or bath: According to the 2022 Cost vs. Value Report by Remodeling Magazine, a kitchen or bathroom remodel can provide more than 50% in recouped value. If you make quality upgrades, like changing out laminate for granite countertops or having custom cabinets built, you may need to increase the dwelling coverage on your home insurance, which usually comes at an additional premium cost. If your home coverage is not enough to rebuild your new kitchen or bath with the same newly upgraded materials, consider increasing the dwelling coverage to align with your upgrades.

If your existing coverage is not sufficient, you might find yourself having to pay out of pocket for some of the damages to your kitchen or bath after a covered loss.

Renovations that lower home insurance rates

If you are making changes that make your home safer, like updated electrical or plumbing systems, you might see lower rates after you and your insurance provider evaluate your home renovation insurance needs.

Renovating or replacing your roof: Installing a new roof may not be the most exciting home improvement, but it may save you money on your homeowners insurance. Replacing your roof with newer or stronger material usually means a reduction in premium because your home may be able to better withstand potential covered perils.

Some homeowners may earn even bigger discounts if they live in states prone to hurricanes, wind or hail and their new roof employs special loss-mitigation measures, such as hurricane straps, waterproofing or impact-resistant shingles.

Upgrading your wiring or plumbing: If you upgrade your wiring or plumbing systems, especially if they are older or no longer up to current building codes, you may qualify for an insurance discount. While rewiring a house can be expensive, it could also lower the risk of fires and electrical damage, which means insurance companies could charge you less for coverage because of reduced risk.

The same holds true for plumbing. Some types of plumbing, like lead and polybutylene, can make it difficult and expensive to find home insurance coverage. Upgrading to more modern plumbing hardware may reduce the risk for water damage and reduce your home insurance premium.

Adding security systems and sprinklers: Home security discounts are relatively common in the insurance industry, and there’s usually some variance in the savings levels.

For example, if you install a local alarm system that rings at your home in the event of an intruder, you may earn a small discount. An alarm system that automatically alerts police or a central dispatch team would likely earn a higher discount.

Interior sprinkler systems may also lower your premiums, as they reduce the risk of extensive fire damage. Installing smart home devices and systems might also earn you a discount.
