Flower Mound, TX Accessory Structures: Tiny Homes (2026)

Flower Mound does not have a specific tiny home ordinance or zoning category. Tiny homes on permanent foundations are treated as standard dwelling units and must comply with all adopted International Residential Code requirements, including minimum habitable room sizes (70 square feet with no dimension less than 7 feet), minimum ceiling heights (7 feet for habitable rooms), kitchen and bathroom requirements, egress window standards, and full utility connections including water, sewer, and electrical service. The dwelling must meet minimum lot size and setback requirements for the applicable zoning district under Chapter 98. Tiny homes on wheels (THOWs) are classified as recreational vehicles under Texas law and Flower Mound zoning. RVs cannot be used as permanent residences in residential zoning districts. They must be stored behind the front building line and screened from street view per the town's RV parking ordinance. Most Flower Mound HOAs have minimum home size requirements in their CC&Rs, typically 2,000 to 3,500 square feet, which effectively prohibit tiny homes in master-planned communities. Agricultural zoning districts may offer more flexibility for small dwelling units. Accessory dwelling units that might qualify as tiny homes are subject to ADU restrictions that generally prohibit independent rental use.
