Do I need a permit for pavers, driveway, or hardscape in Katy?

Most likely yes. Pavers, driveway, or hardscape usually requires a permit in Texas. Confirm the specifics with Katy.

At-grade patios, walkways, and paver areas are often exempt, but many Texas cities regulate added impervious cover, driveway approaches in the public right-of-way, and drainage. A retaining wall above a set height typically requires its own permit and engineering. Confirm impervious-cover limits and right-of-way rules with your local building department. Katy's Permit and Building Services page lists sidewalks, driveways and patios among the work requiring a permit, and Katy Code Sec. 3.02.054(2) does not adopt the IRC R105.2 exemption for sidewalks and driveways. Katy's flatwork fees are $8 for the first driveway, $30 for up to 1,000 square feet of flatwork or paving, and $15 for the first 100 feet of sidewalk, plus the $30 application fee. Katy's specs call for residential driveways of at least 3.5 inches of 2,500 PSI concrete with #6 wire mesh or #3 rebar at 18 inches, and 4-inch patio slabs with #3 rebar at 16 inches. Under Zoning Ordinance Sec. 16.4-9, flatwork may extend past the side yard building line to the property line but not into alleys or drainage or utility easements. No change to a permitted driveway, including its pavement, may be made without the city's approval.
