Do you need a permit for a carport in Houston?
Yes: the City of Houston requires a building permit for new construction, and the Houston Permitting Center issues it.
The City of Houston Planning carport brochures are dated 2021. They say the State Building Code and the Houston Code of Ordinances require building permits for new construction inside the city.
The brochures give no size threshold for a carport, so confirm the rule for your size with the Houston Permitting Center before you order.
For a permit application, the city lists a site plan, the recorded subdivision plat, a survey, and architectural or engineered drawings.
These rules cover addresses inside the City of Houston. An address outside the city limits follows the rules of the city or county that covers it.
For the general rules on when a permit is needed, read the carport permit rules guide.
Where can a carport go on a Houston lot?
No part of a carport in Houston may sit inside the setback or the right-of-way, which the city places behind the sidewalk.
The brochures say the property or right-of-way line is typically behind the sidewalk. A setback line can come from the recorded subdivision plat, from deed restrictions or from a city ordinance.
Houston has no zoning, as City of Houston Planning notes, so the plat and any deed restrictions matter. Check your plat, your deed restrictions and any HOA covenant before you place a carport.
The diagram below reads from the street inward: the sidewalk, the right-of-way line, the setback line and the house. The carport footprint stays behind the setback line.
If a carport sits in the setback or the right-of-way without a permit, the brochures list three remedies. The owner can remove it, modify it, or seek a variance from the Planning Commission.
What wind rating does a Houston carport need?
Houston sets the basic wind speed for each address under ASCE 7-2022, so the number comes from your address and not from a city-wide table.
ASCE 7-2022 is the American Society of Civil Engineers standard for design loads. The city enforces it with the 2021 IBC and 2021 IRC.
The Houston Building Code Design Criteria, revised May 2025, list the IRC basic wind speed as site specific and point to the ASCE 7 wind speed website. The sheet lists exposure category B.
The diagram shows three steps: your address, the ASCE 7-2022 wind map for the risk category, and the basic wind speed your engineer uses. It prints no speed, because the value depends on the address.
You can look up a value for an address in the ASCE Hazard Tool. Ask the seller for the engineering sheet that names the edition, the risk category and the wind speed used.
For past context, the National Weather Service Houston/Galveston office recorded a highest gust of 89 mph in Harris County during Hurricane Beryl on July 8, 2024. That gust is a past event and not a design wind speed.
Is Houston in the TWIA windstorm area?
Only the part of Harris County east of Highway 146 is in the TWIA first-tier area.
TWIA is the Texas Windstorm Insurance Association. Its coverage eligibility page lists 14 first-tier counties, and in Harris County only the part east of Highway 146 qualifies.
A structure that seeks TWIA coverage must be certified as built to the applicable building codes, with limited exceptions. Check your address with TWIA before you buy.
Snow, frost, soil and flood zones in Houston
Houston's design criteria list a ground snow load of 0, a frost line of 6 inches and an expansive soil class.
Expansive soil swells and shrinks with moisture, so it affects how footings and anchors are chosen. Ask your engineer which footing the soil class calls for.
In flood Zones A, AO and AE, a single-family outdoor improvement that stays under 50% of the structure's appraised value can use permit HPWFMO1004. The Houston Permitting Center lists carports as eligible and gives a processing time of 1 to 3 business days.
Check the flood map for your address before you plan the footprint.
What do Houston permits cost?
The 2026 Houston fee schedule sets a $33.56 administrative fee and a $91.06 minimum permit fee.
It also sets a plan review fee of 25% of the estimated building permit fee. The administrative fee and the plan review fee are listed as non-refundable.
The schedule has no carport line item, so the total for a carport depends on how the Houston Permitting Center values it. Ask the center for a figure for your carport before you set a budget.
