Home Remodeling in Houston

A Houston remodel starts with a question most cities never ask: how high does the floor sit? After Harvey put water into more than 120,000 buildings in Harris County, the city and the county rewrote their floodplain rules, and a big enough project on a low lot now has to rise above the 500-year flood line. Add clay that swells in wet months and cracks open in dry ones, and the first money in a Houston budget often goes under the house before it goes into the kitchen.

What changes a remodel in Houston.

Harvey flooded more than 120,000 structures in Harris County, and the rules changed after it

Harris County Flood Control District counts 1 trillion gallons of rain over four days in August 2017, with a peak of 47.4 inches near Clear Creek at Interstate 45. The county usually gets about 50 inches in a whole year. In response, Houston amended Chapter 19, its floodplain ordinance, in April 2018, effective September 1, 2018. A substantial improvement to a house in the 100-year floodplain (land with a 1 percent chance of flooding in any year) must now be built 2 feet above the 500-year flood elevation (the 0.2 percent chance line). That can turn a large remodel into a house raise, so check your lot on the flood map before you design anything.

Much of the metro sits on clay that cracks open when it dries

The Lake Charles soil series, which the USDA maps across southeast Texas between the Colorado and Trinity Rivers, is 45 to 60 percent clay of the smectite type, the kind that swells when wet and shrinks when dry. In dry spells it opens cracks up to 2 inches wide at the surface that reach 12 inches or deeper, and they stay open 60 to 90 days in most years. That movement is why slab repair tops local searches, and why a floor that is out of level should be checked before new tile or cabinets go on top of it.

Houston has no zoning, so deed restrictions set the limits

Houston is not zoned, and a 2003 Texas Senate bill analysis says the city relies on deed restrictions to keep incompatible uses out of neighborhoods. The City Attorney's office can sue to enforce restrictions on how a lot is used, building setbacks, lot size, the size, type and number of structures on a lot, a structure's orientation, and some fences. Before you plan an addition, a second story or a garage apartment, read the restrictions recorded for your subdivision. They can stop a project the building code would allow.

Part of Harris County is in the Texas windstorm catastrophe area

The Texas Windstorm Insurance Association covers the parts of La Porte, Morgan's Point, Pasadena, Seabrook and Shoreacres that are inside city limits and east of Highway 146. For those homes, TWIA requires a certificate of compliance, known as a WPI-8, for any structure built, altered, remodeled, enlarged or repaired on or after January 1, 1988. A new roof or new windows there need the windstorm inspection as the work goes in, or the house can lose access to that coverage.

What a remodel costs in Houston in 2026.

$23,503

Midrange bathroom remodelModeled average job cost for Houston; 75.2 percent of it comes back at resale

Start with what Houston owners actually spend. The Census Bureau's 2023 American Housing Survey found that owners in the Houston metro took on 2.58 million improvement projects over two years. When they hired the work out, the median project cost $3,500. When they did it themselves, it was $800. Most of those jobs are repairs and replacements, not full rooms, so treat them as a floor for what a real remodel runs.

For full projects, the 2025 Cost vs Value report models Houston on its own. A midrange bathroom remodel comes to $23,503 and a midrange major kitchen remodel to $81,521, both a little under the national figures. A new asphalt shingle roof is $27,519. The same report shows how much of that comes back at sale: 75.2 percent for the bathroom, 46.8 percent for the major kitchen, and 106.1 percent for a minor kitchen remodel at $28,300.

Labor is part of why Houston comes in under the national numbers. Federal wage data for May 2025 put the median Houston carpenter at $23.88 an hour against $29.12 nationally, and the median roofer at $21.87 against $26.65. Plumbers and electricians sit closer to the national line. The costs that are special to Houston sit outside these tables: a foundation that needs work first, or a flood rule that turns an addition into a raise.

Who issues permits in Houston.

Who issues your permit depends on where the house sits. Inside Houston city limits it is the Houston Permitting Center. In unincorporated Harris County it is the county's Office of the County Engineer, and in unincorporated Fort Bend County it is the Fort Bend County Engineering Department. Inside another city limit, that city's building office is the one to call. All three agencies below also check floodplain rules, and that review is often what sets the schedule on a Houston remodel.

  • In Houston, a residential remodel permit requires plan review and inspections. The permit is valid for 6 months, the city lists processing at 1 to 15 business days, and the admin fee is $33.10 on top of the fee schedule.
  • Taking out a load-bearing wall in Houston means the plans must show which way the ceiling joists run and where the new header and beam go.
  • Houston remodel plans must show compliance with the 2015 International Energy Conservation Code, or include a REScheck or IC3 report.
  • Trade inspections in Houston have to be scheduled by the registered licensed contractor for that trade.
  • Under Houston's Chapter 19, an addition larger than one third of the home's footprint, in either the 100-year or 500-year floodplain, must be built 2 feet above the 500-year flood elevation. A smaller addition in the 100-year floodplain needs 1 foot above the 100-year elevation.
  • In unincorporated Harris County, a substantial improvement is work costing 50 percent or more of the structure's value, measured against the Harris County Appraisal District market value. The lowest floor must then sit 24 inches above the 500-year flood elevation or 12 inches above the crown of the nearest street, whichever is higher.
  • In unincorporated Fort Bend County, a residential development permit is required for a new structure or an addition of 400 square feet or more, and for any work in the 100-year floodplain.

What Houston homeowners plan most.

Foundation repair

Clay soils across the metro swell and shrink with the seasons, and slab movement shows up as cracked tile, sticking doors and floors out of level.

Bathroom remodel

The most searched room project in Houston. The 2025 Cost vs Value model puts a midrange one at $23,503.

Kitchen remodel

A minor midrange kitchen remodel is one of the few projects that returned more than its cost at sale in Houston in 2025.

Roof replacement

Gulf storms put roofs under strain, and homes east of Highway 146 in five Harris County cities need a windstorm certificate for the work.

Flooring

Floors are the first finish lost when water comes in, and replacement often starts with checking the slab underneath.

Pool remodel

Resurfacing and new equipment stay inside the pool, but new decking or a cabana on the lot has to respect the setbacks in your deed restrictions.

Before you start.

How much does a bathroom remodel cost in Houston?

The 2025 Cost vs Value report puts a midrange bathroom remodel in Houston at $23,503, below the $26,138 national figure, and about 75 percent of that comes back when the house sells. An upscale bathroom remodel is modeled at $75,005. Census data shows the median hired-out improvement project in the Houston metro costs $3,500, so smaller updates cost far less than a full room.

Do I need a permit to remodel my house in Houston?

Inside city limits, remodels, conversions and additions go through the Houston Permitting Center with plan review and inspections. The permit is valid for 6 months and processing is listed at 1 to 15 business days. Unincorporated Harris County and Fort Bend County issue their own permits through their county engineering offices, and both review floodplain rules.

Do I have to raise my house if I remodel in a Houston floodplain?

Possibly. Under Houston's Chapter 19, a substantial improvement in the 100-year floodplain must be built 2 feet above the 500-year flood elevation. FEMA defines substantial improvement as work costing 50 percent or more of the building's market value before the project. Additions larger than one third of the footprint face the same elevation rule in either floodplain.

Why do so many Houston homes need foundation repair?

Much of the metro sits on clay soils like the Lake Charles series, which the USDA describes as 45 to 60 percent clay that shrinks and swells. In dry spells it cracks up to 2 inches wide and 12 inches or more deep. That seasonal movement lifts and drops slab foundations, which is why foundation repair is Houston's most searched home project.

Can deed restrictions stop my remodel in Houston?

Yes. Houston has no zoning, so recorded deed restrictions do much of that work. The City Attorney's office can sue to enforce limits on how a lot is used, setbacks, lot size, the size and number of structures, orientation and some fences. Read your subdivision's restrictions before planning an addition or second story.

What does a new roof cost in Houston?

The 2025 Cost vs Value report models an asphalt shingle roof replacement in Houston at $27,519, and 68.9 percent of it comes back at resale. A metal roof is modeled at $44,883. In La Porte, Morgan's Point, Pasadena, Seabrook and Shoreacres east of Highway 146, roof work also needs a WPI-8 windstorm certificate.
