In Miami, the renovations that recoup the most at resale are small, visible exterior projects and modest kitchen updates. The 2025 Cost vs. Value Report puts a garage door replacement at about 217 percent of cost recouped and a midrange minor kitchen remodel at about 107 percent, while upscale kitchens, upscale bathrooms and large suite additions recover less than half of what they cost. Florida adds a category the national data barely captures: roof, window and door upgrades that make a house easier to insure.
That last point matters more here than almost anywhere in the country. A buyer who cannot get reasonable insurance cannot close, and an appraiser cannot ignore a 20-year-old roof. Here is what the numbers say, what they leave out, and how we would rank the options if the goal is resale value rather than personal enjoyment.
Which renovations have the best return in Miami?
The Cost vs. Value Report, published through the Journal of Light Construction, estimates what common projects cost and what real estate professionals believe they add at resale. Its 2025 figures for the Miami market, the most recent edition available as of 2026, look like this:
| Project (2025, Miami) | Typical job cost | Value at resale | Cost recouped |
|---|---|---|---|
| Garage door replacement | $5,821 | $12,624 | 216.9% |
| Steel entry door replacement | $2,466 | $4,593 | 186.3% |
| Minor kitchen remodel, midrange | $29,424 | $31,584 | 107.3% |
| Backup power generator | $13,580 | $13,326 | 98.1% |
| Window replacement, vinyl | $22,056 | $16,718 | 75.8% |
| Bath remodel, midrange | $25,565 | $19,190 | 75.1% |
| Bath remodel, universal design | $40,234 | $25,003 | 62.1% |
| Major kitchen remodel, midrange | $83,468 | $40,740 | 48.8% |
A separate survey, the 2025 Remodeling Impact Report from the National Association of Realtors and NARI, points the same way: a new steel front door was estimated to recover 100 percent of its cost, and a bathroom renovation about 50 percent.
How to read these numbers
The report is useful, but it has limits that matter for South Florida homes.
- The costs are model projects, not your project. Each line describes one defined scope in a standard-sized house, and the report’s “minor kitchen remodel” is a lighter job than many of the kitchen projects we see in Miami. Our kitchen remodel cost guide explains how real projects here price.
- Resale value is an opinion survey. It reflects what agents believe a project adds, not a measured sale price.
- The window line is vinyl replacement, not impact glass. It says nothing about insurance savings, which is where impact windows earn much of their keep in Florida.
- Percentages flatter cheap projects. A 200 percent return on a $5,800 garage door is about $6,800 of value. A 48 percent return on an $83,000 kitchen is still $40,000 of value. Return on investment and impact on price are different questions.
The Florida-specific upgrades that national data misses
Roof
Florida law limits how insurers treat roof age. Under section 627.7011, for policies issued or renewed since July 1, 2022, an insurer cannot refuse to write or renew a home solely because its roof is less than 15 years old. For a roof 15 years or older, the homeowner can pay for an inspection, and if it shows at least five years of useful life remaining, the insurer cannot refuse coverage on roof age alone.
The practical effect for a seller: a buyer with an older roof on the house may face a harder insurance search, and that friction shows up in negotiations. National data shows roofing recouping well under its cost, but in South Florida a sound roof is often closer to a condition of sale than an upgrade. In the NAR survey, new roofing was the third most common project agents recommended before selling.
Impact windows and doors
Under section 627.0629, Florida insurers must include actuarially reasonable discounts or credits in their rate filings for features that reduce windstorm losses, including opening protection and roof-to-wall strength. Since October 2023, insurers must also describe their hurricane mitigation discounts on their websites. A wind mitigation inspection documents which features your house has.
Impact windows and doors also remove the need for shutters, which buyers notice. The cost is substantial, and our guide to impact windows and doors cost in Florida covers typical ranges. The value case rests on three things together: insurance credits, hurricane readiness, and a house that does not need shutters put up every time a storm approaches.
The My Safe Florida Home program
As of 2026, the state’s My Safe Florida Home program offers free wind mitigation inspections and grants of up to $10,000 toward eligible improvements, including impact windows and doors, garage door upgrades, roof-to-wall reinforcement, roof deck attachment and secondary water barriers. Funding depends on the Legislature and eligibility rules apply, so check the program portal before planning around a grant.
Backup power
A generator recouped about 98 percent of cost in Miami in the 2025 report, far better than most interior projects. After a hurricane season with extended outages, that number is easy to understand.
What does not add value in Miami
- Upscale everything. The report’s upscale kitchen, upscale bath and upscale suite addition all recover under 43 percent in Miami. That does not make them bad decisions if you plan to live with them for a decade. It makes them bad decisions if you plan to sell next year.
- Highly personal finishes. A bold tile or a dramatic color palette narrows the pool of buyers. Neutral, durable finishes appraise and sell better.
- Removing the only tub. Some buyers with young children want at least one bathtub. Our article on walk-in shower versus tub resale covers when converting makes sense.
- Unpermitted work. Anything done without a permit can cost you at closing. A buyer’s title search or lien search can surface it, and in unincorporated Miami-Dade, sellers must disclose known illegal construction and code violations.
- Over-improving for the street. A $200,000 renovation on a block where homes sell at $650,000 will rarely come back to you in full. Spend toward the top of your neighborhood, not beyond it.
What we would do if the goal is value
If you are planning to sell within a few years, our order of priorities usually looks like this:
- Fix what a buyer’s inspector or insurer will flag: roof condition, active leaks, electrical hazards, old plumbing, and any open or expired permits.
- Protect the openings: impact doors and windows, starting with the front entry and the garage door, which both score well in the report.
- Refresh rather than rebuild the kitchen: new counters, cabinet doors or paint, lighting and appliances in the existing layout.
- Bring bathrooms up to date in their current footprint, with proper waterproofing behind the tile. Our bathroom remodeling page covers how we approach that.
- Paint and floors throughout. In the NAR survey, painting the entire home was the project agents most often recommended before selling.
On the Hollywood Lake House, a 1960s lakefront home taken back to structure, the scope included the roof and windows as well as the kitchen and all four bathrooms. The envelope comes first on a house like that, and the same logic applies when the goal is resale.

Frequently asked questions
What home improvement adds the most value in Miami?
By percentage recouped, small exterior projects lead. In the 2025 Cost vs. Value Report for Miami, garage door replacement recouped about 217 percent and a steel entry door about 186 percent. Among larger projects, a midrange minor kitchen remodel recouped about 107 percent. In South Florida, a sound roof and impact openings also matter because they affect insurability.
Do impact windows increase home value in Florida?
They help in ways national data underestimates. Florida insurers must include windstorm mitigation discounts or credits for features such as opening protection in their rate filings, and impact glass removes the need for shutters. The Cost vs. Value Report only tracks vinyl window replacement, at about 76 percent recouped in Miami, so it does not reflect impact glass or insurance savings.
Is a kitchen remodel worth it before selling in Miami?
A modest one usually is. A midrange minor kitchen remodel recouped about 107 percent of cost in Miami in 2025, while a midrange major remodel recouped about 49 percent and an upscale one about 34 percent. If you are selling soon, refresh within the existing layout. Save the full rebuild for a kitchen you will use for years.
Does a new roof add value in South Florida?
It often protects value more than it adds it. Under Florida law, insurers cannot refuse coverage solely because a roof is under 15 years old, and older roofs may need an inspection showing at least five years of remaining life. A buyer who struggles to insure the house may lower their offer or walk, so an aging roof is a negotiation problem.
Are there grants for hurricane upgrades in Florida?
As of 2026, the My Safe Florida Home program advertises free wind mitigation inspections and grants of up to $10,000 for eligible upgrades such as impact windows and doors, garage door reinforcement and roof improvements. Availability depends on state funding and eligibility rules, so confirm on the program’s portal before committing to a project based on a grant.
