Arlington, TX Accessory Structures: Carport Rules (2026)

Arlington regulates carports as accessory structures or extensions of the main dwelling, depending on whether they are attached or detached. A building permit is required for any permanent carport regardless of size because structural framing and foundation anchoring must comply with the International Residential Code's wind load requirements, typically designed for the 115-mph basic wind speed applicable to North Texas. Attached carports extend the primary structure and must meet the zoning district's front, side, and rear setbacks for the main dwelling, commonly 25 feet front, 5-10 feet side, 20 feet rear. Detached carports fall under accessory structure rules with typical setbacks of 3 feet from side and rear lines and placement behind the front building line. Posts, beams, and roofing must be permanently anchored; fabric, tarp, or unsecured metal carports sold at big-box retailers typically do not meet Arlington's structural or aesthetic standards and cannot be placed as permanent front-yard structures, though they may be allowed temporarily or in rear yards depending on HOA and zoning. Roof materials must match the main house or comply with district aesthetic standards. Impervious cover and total accessory coverage limits apply. HOA architectural committees frequently impose stricter rules, including prohibitions on metal carports, material color requirements, and minimum roof pitch. Carports used for commercial vehicle storage or as open-sided workshops may trigger home occupation scrutiny.
