La Porte, TX Accessory Structures: Tiny Homes (2026)

La Porte's zoning ordinance establishes minimum dwelling unit sizes for residential districts. Single-family homes must meet minimum floor area requirements, which typically range from 1,000 to 1,400 square feet depending on the zoning district. This effectively prevents construction of tiny homes (generally under 400 square feet) as primary residences without a variance. Tiny houses on wheels (THOWs) are classified as recreational vehicles under Texas law and La Porte's code. As RVs, they may be stored on residential property subject to the city's RV parking regulations but cannot be occupied as a permanent dwelling. Living in an RV on residential property violates the zoning ordinance. Tiny homes on permanent foundations that meet the minimum square footage requirement for the zoning district and comply with the International Residential Code may be permitted, but at that size they would no longer be considered tiny homes. The building code requires all dwellings to have minimum room sizes, ceiling heights (7 feet), egress windows, permanent utilities (water, sewer, electric), and meet wind load requirements for La Porte's coastal location. There is no city-level tiny home program or exception. Variances for reduced dwelling size would require Board of Adjustment approval and demonstration of hardship.
