Updated November 2026. Home improvements that boost property value can also boost your property tax bill. Here’s which work gets assessed, which doesn’t, and how the rules differ in Florida, Texas and California. State statutes, the California Board of Equalization and IRS pages were read on November 12, 2026.
Home improvements usually increase property taxes when they add something new, like a room, a pool or square footage. Routine repairs and maintenance usually don’t. As of November 2026, Florida adds new work on a homestead at full value the January 1 after it’s done. California says normal upkeep and repairs typically aren’t taxed as new construction.

Key takeaways
- Additions and new features are usually assessed; repairs and upkeep usually aren’t. Your county assessor decides case by case.
- Florida’s Save Our Homes cap limits yearly homestead increases to 3% or inflation, whichever is lower, but improvements are added at just value on top.
- Texas caps a homestead’s yearly appraisal increase at 10%, plus the market value of new improvements; repairs and ordinary maintenance don’t count as new.
- In Florida, the value of residential solar equipment may not be counted in the assessment.
Everyone loves the payback tables. A new steel front door gets back an estimated 100% of its cost, per NAR and NARI’s 2025 Remodeling Impact Report (NAR release). Fewer people ask the next question. If a project makes the house worth more, will the county notice? Often, yes. Here’s how to tell before you build.
Do home improvements increase property taxes?
New things usually do. Fixing old things usually doesn’t. That’s the rule in most states, though the words change.
Assessors look for work that adds value the house didn’t have before. Think more square feet, a new bathroom, a pool, a finished basement or a garage turned into a room. They mostly learn about it from building permits. California’s Board of Equalization says they also use required inspections and aerial or satellite photos (BOE, New Construction).
Repairs keep what you already have. Patching a roof, fixing a leak, painting the same walls or swapping a broken water heater for a new one like it is upkeep. Don’t skip a permit to dodge a tax bump, though. Unpermitted work tends to come up again when a buyer’s inspector or lender looks at the house, and that’s a bigger headache.
Which projects raise property taxes, and which don’t?
A quick guide. Your county has the final word, and some cases fall in between.
| Project | Likely to raise the assessment? | Why |
|---|---|---|
| Room addition or second story | Yes | New square footage |
| In-ground pool | Usually | A new feature that didn’t exist |
| Finished basement or garage turned into a room | Usually | New living space |
| Full gut remodel of a kitchen or bath | Sometimes | Can count if it makes the space like new |
| New roof with similar materials | Usually not | Replacing what was there |
| Interior or exterior paint | Usually not | Maintenance |
| New water heater or AC to replace a broken one | Usually not | A repair |
| Rooftop solar (Florida) | No | State law excludes its value for homes |
The “sometimes” row is where people get surprised. In California, a remodel that makes part of the house as good as new counts as a “major rehabilitation”. That’s new construction. A quick refresh of the same kitchen usually isn’t. Not sure? Call the assessor’s office before you pull the permit and describe the job.
How do Florida, Texas and California assess improvements?
Florida. A homestead’s assessed value can rise each year by no more than 3% or the change in the Consumer Price Index, whichever is lower (Florida Statutes 193.155). But new work is added at just value as of the first January 1 after it’s mostly done. So a $60,000 addition finished in October shows up in full the next January, on top of your capped value. Rebuilding after a storm has its own rules in the same law. For how homestead itself works, see our guide to how property taxes work.
Texas. For a homestead, the appraisal district can raise the value by no more than 10% a year, plus the market value of any new improvements (Texas Tax Code section 23.23). A new improvement is one that adds market value. The law leaves out repairs and ordinary upkeep of the house or the grounds. A new roof that replaces an old one is a repair; a new outdoor kitchen isn’t.
California. New construction gets its own value at market price when it’s finished. The rest of the home keeps its old base. If work is only partly done on January 1, the assessor values what’s there. The BOE says normal upkeep and repairs are typically not new construction and aren’t assessed.
Think the new number is wrong? You can appeal it. Our steps to check and appeal an assessment cover the deadlines and evidence.
Do solar panels or energy upgrades raise property taxes?
In Florida, no. For homes, Florida Statutes 193.624 says the value of solar panels, inverters and similar gear installed since 2013 may not be counted in the assessment. Other states have their own exemptions, so check yours.
Will solar raise the sale price? That’s a different question. Forbes Home looks at whether solar can amplify your home’s value. The answer depends on your market and on who owns the panels. A lease has to pass to the buyer, which can slow a sale.

Buy a home →The federal credits that helped pay for energy work have ended. The IRS says the Energy Efficient Home Improvement Credit covered work done through December 31, 2025. The Residential Clean Energy Credit isn’t available for property placed in service after that date. For smaller energy jobs, see 4 things to start replacing at home.
Do repairs and prep work count?
Mostly not. That’s good news for the jobs buyers see first. Repainting, sealing and fixing rust are upkeep. If you’re working on steel railings, gates or a metal carport, a weldable primer keeps bare steel from rusting without blocking the weld. That’s a repair, not new construction.
Older homes need one check before any sanding. Lead paint was banned for home use in 1978. The EPA says it’s still in millions of homes, and peeling or chipping lead paint is a hazard. Sellers of homes built before 1978 must disclose lead paint they know about (EPA, real estate lead disclosures). Our interior painting guide covers safe prep.
How do improvements help when you sell?
A higher tax bill now can mean a lower one later. Here’s why. IRS Publication 523 says improvements add value, make the home last longer or adapt it to new uses. Their cost is added to your basis. Repairs and upkeep aren’t, unless they’re part of a bigger remodel. A higher basis means a smaller taxable gain if your profit goes past the $250,000 exclusion ($500,000 for most married couples filing jointly). Our guide to avoiding capital gains tax on a home sale runs the numbers.
So keep every receipt, contract and permit. Put them in one folder. Then list the work with years in your listing: “2025 permitted primary suite addition” tells buyers and appraisers more than “updated.” For bigger projects, read which extensions add value and our ranking of renovations that raise property value.
