How Home Renovations Affect Insurance Rates in Ohio
Home renovations are exciting—whether you’re transforming an outdated kitchen, adding square footage, finishing a basement, or restoring one of Ohio’s historic homes. But while renovations almost always increase comfort and property value, many homeowners are surprised to learn how dramatically they can affect insurance rates. In a state like Ohio—where homes range from early 1900s brick architecture to modern suburban construction—updates and remodels have significant implications for replacement cost, liability exposure, and overall underwriting risk. This guide explains how renovations influence insurance pricing, what upgrades increase premiums or reduce them, and how to protect your investment during and after a remodel.
Why Renovations Matter to Insurers
Insurance rates are based primarily on one metric: how expensive the home would be to rebuild after a total loss. Renovations directly influence this figure, often raising replacement cost because modern materials, labor, and building codes are more expensive than what existed when the home was first constructed. A kitchen remodeled in 2024 costs significantly more to replace than a kitchen built in 1984. Likewise, adding square footage or finishing a basement expands the insured structure, requiring additional coverage.
Ohio homeowners face unique challenges in this area. Dayton, Kettering, Oakwood, and many surrounding suburbs are filled with homes built between the 1920s and 1970s. Renovations often include electrical upgrades, plumbing replacements, roof improvements, and structural changes—all of which insurers evaluate closely. In older neighborhoods such as Belmont, South Park, and Grafton Hill, renovations may bring the home closer to modern standards, while in upper-Kettering, Centerville, and Washington Township, renovations often introduce premium materials that elevate the home into a higher replacement-cost tier.
Which Renovations Increase Insurance Rates?
Any improvement that increases the cost to rebuild the home will affect your insurance premium. Popular renovation types in Ohio include kitchen remodels, bathroom updates, finished basements, room additions, and specialty features such as covered patios, outdoor kitchens, or high-end flooring. Each of these changes increases both the rebuilding costs and, in some cases, the risk profile.
Kitchen and bathroom renovations often lead to the highest increases because they involve premium materials—stone countertops, custom cabinetry, tiled showers, upgraded appliances, and modern plumbing. Adding square footage, such as converting attic space or building a room addition, also increases the dwelling limit and the insurer’s exposure. Even renovations that seem minor, like refinishing hardwood floors or replacing carpet with luxury vinyl, can increase replacement cost in aggregate.
Outdoor additions also matter. A new deck, pergola, or detached structure such as a shed or studio introduces additional coverage needs. Pools, hot tubs, and elaborate landscaping can raise liability exposure, especially if they involve electrical components or water hazards.
Which Renovations Lower Insurance Rates?
Not all renovations result in higher premiums. In fact, some upgrades can reduce insurance costs by lowering risk. Electrical system updates—particularly replacing knob-and-tube wiring or aluminum wiring—often result in improved eligibility and better pricing. Replacing old plumbing, updating the roof, reinforcing foundational elements, and installing modern safety systems such as water leak sensors or fire-suppression devices can significantly mitigate risks.
For example, an older home in Oakwood or Kettering that replaces galvanized steel plumbing with PEX piping may see improved underwriting results. A roof replacement in a storm-prone area like Beavercreek or Vandalia may also reduce wind-related risks. Similarly, updating a home’s HVAC system or adding insulation and modern windows reduces strain on mechanical systems and enhances overall safety.
While these improvements may not always drop premiums substantially, they do help keep rates from rising, improve eligibility with more competitive carriers, and ensure coverage remains robust.
How Renovations Affect Replacement Cost Valuations
Replacement cost valuations are at the heart of home insurance. These valuations represent what it would cost to rebuild the home from the ground up after a catastrophic loss. Renovations affect this number in two ways: through material upgrades and through expanded square footage.
When a homeowner replaces laminate countertops with quartz or granite, installs hardwood instead of carpet, or adds custom trim, the home becomes more expensive to rebuild. Insurers take note of this, and dwelling coverage limits must be adjusted accordingly. Ohio’s home values vary significantly across regions, but construction costs have risen statewide, making accurate replacement cost assessments more important than ever.
Homes in high-end districts—such as Oakwood’s Far Hills corridor, Kettering’s Trail’s End neighborhood, and Washington Township’s custom-built communities—often feature premium materials that require careful consideration. Failing to update coverage after renovations can lead to significant underinsurance, forcing homeowners to pay out-of-pocket during a claim.
Renovations and Code Compliance: Ordinance or Law Coverage
Older Ohio homes almost always trigger code compliance issues during renovation or after a covered loss. Homes built in the early and mid-20th century frequently lack modern electrical grounding, proper insulation, updated plumbing, or code-compliant stairways and egress windows. When renovating, homeowners often become aware of these shortcomings for the first time.
If a covered loss occurs, Ordinance or Law coverage becomes essential. This endorsement pays for bringing damaged portions of the home up to current building codes, and in some cases, for demolishing undamaged portions when required. Renovations reveal—and sometimes correct—older deficiencies, but they can also expose additional areas that would require code upgrades during reconstruction.
Protecting Your Home During the Renovation Process
Many homeowners do not realize that large renovations require adjustments to the insurance policy while the work is being performed. If a contractor is altering the structure, knocking down walls, or installing new mechanical systems, the home may temporarily become a higher risk.
Homeowners should ensure that contractors carry their own liability insurance and workers’ compensation coverage. Additionally, depending on the scope of the renovation, a Builder’s Risk endorsement may be necessary. This endorsement covers theft of building materials, vandalism at the job site, or damage to the home while under construction. In neighborhoods with tight spacing between homes or busy contractor traffic—such as parts of Dayton, Riverside, or Kettering—these protections are especially important.

Local Examples: How Renovations Affect Ohio Homes
In Kettering’s custom-home corridors, homeowners frequently add finished basements or expand kitchens—both of which raise replacement cost valuations significantly. In Oakwood, historic-era renovations often uncover old electrical or plumbing systems, which leads to increased premiums if not updated. Meanwhile, in Beavercreek and Vandalia, roof replacements or structural reinforcements can reduce long-term risk, stabilizing premiums over time.
Even smaller renovations can have insurance consequences. Replacing flooring throughout a home, installing recessed lighting, updating trim work, or adding built-ins all enhance the home’s reconstruction cost. These improvements should be communicated to the insurer to ensure dwelling coverage remains sufficient.
Why Working with a Local Independent Agent Matters During Renovations
Renovations create a moving target for insurers. Replacement costs shift, risk profiles evolve, and certain phases of construction require temporary protections. A national call center or direct-to-consumer insurer cannot provide the nuanced guidance needed for Ohio’s diverse housing stock.
Local independent agents understand the differences between renovating a 1925 brick home in Dayton, upgrading a mid-century ranch in Kettering, or expanding a high-value property in Washington Township. They can help adjust coverage limits, evaluate whether certain endorsements are necessary, and ensure that homeowners remain protected throughout every phase of the renovation.

Working with a knowledgeable local agent makes the process seamless and ensures that every update is fully protected from day one.
