La Porte, TX Accessory Structures: Carport Rules (2026)

La Porte regulates carports as accessory structures under the city's zoning and building codes. A building permit is required for carport construction regardless of size. The permit application requires a site plan showing the proposed carport location relative to property lines, easements, and existing structures. Setback requirements apply: carports generally must be set back from side and rear property lines per the zoning district standards (typically 5 feet from side and rear). Front-yard carports may be subject to specific design requirements or may require the structure to be set back to the front building line of the principal structure. Carports must not block sidewalks or encroach on public rights-of-way. The carport footprint counts toward the maximum lot coverage allowed in the zoning district. Construction must comply with the International Residential Code including wind load requirements appropriate for La Porte's Gulf Coast location, where design wind speeds are elevated due to hurricane risk. Carport posts and foundations must be engineered for the applicable wind loads. Metal carports must be anchored to concrete footings or a slab. Temporary or portable carport canopies may be subject to different regulations and may not be permitted as permanent structures in some zoning districts.
