Brownsville, TX Accessory Structures: Carport Rules (2026)

Brownsville regulates carports as accessory structures under the Unified Development Code, originally adopted in 2020 (with the November 25, 2020 zoning district standards) and administered by the Planning and Redevelopment Department at 1034 E. Levee Street. Carports, whether attached to a home or freestanding, must comply with the front, side, and rear yard setbacks established in UDC Article 4 for the underlying residential district (R-1, R-2, R-3, etc.) and the supplemental rules for accessory structures in Article 5. Detached carports are typically located in the rear or side yard and must observe side and rear setbacks of the residential district; an attached carport is treated as part of the principal structure and must meet the principal-building setbacks. A residential building permit is required from the Building Permits and Inspections Division (1001 E. Elizabeth Street, 956-546-4357), with plan review against Brownsville's adopted International Residential Code and International Building Code editions per Code of Ordinances Chapter 18, Article III. Plans must show post sizes, footing depth, roof framing, lateral bracing for South Texas wind loads, and drainage. Because Brownsville sits in Cameron County on the Gulf Coast, carports are subject to the higher wind-design provisions of the IRC for Hurricane-prone Regions and Wind-Borne Debris Regions. Properties in mapped FEMA floodplains must additionally satisfy Brownsville's Flood Prevention ordinance (Chapter 18 Floodplain Management).
