Deck Construction Permits in Houston

Local Rule

Houston Public Works / Houston Permitting Center

The city's own permitting guidance states the exemption by height alone: uncovered decks accessory to a one- or two-family dwelling, up to 30 inches above the ground, need no permit, with no separate square footage cap in that specific item; a covered deck or one over 30 inches needs a permit regardless of size. Houston is the largest U.S. city with no zoning ordinance at all, so there is no separate zoning review layer for a deck, only building code compliance and whatever deed restrictions apply to the specific subdivision. Much of Houston sits in a floodplain, so properties in FEMA-designated flood zones face additional elevation and foundation requirements even for an otherwise-exempt deck.

How This Compares to Harris County

Houston's own rule is shown above (Depends on project scope). Here is the separate rule that applies at the county level, for context:

City of Houston Public Works / Harris County Engineering

Harris County splits between unincorporated areas and the City of Houston. In the City of Houston, a building permit is NOT required for an uncovered wood deck accessory to a one- or two-family dwelling that meets ALL of these: no more than 200 square feet in area, no more than 30 inches above grade at any point, not attached to the dwelling, and not serving the exit door required by Section R311.4. Cross any of those thresholds, cover it, raise it above 30 inches, or attach it to the house, and a building permit through the Houston Permitting Center is required (iPermits/ProjectDox). Houston is the largest U.S. city with no zoning, so the building permit is usually the only city approval, but the city still enforces setbacks (about 5 feet from side and rear lines), and private deed restrictions filed with Harris County (and any HOA architectural review) are separate and can block a deck even if the city would allow it. General contractors are not required to be licensed in Houston o
