Tiny home rules in Brazoria County, TX — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Brazoria County cannot set a minimum house size or zone tiny homes in unincorporated areas — only septic, platting and floodplain rules apply. Inside a city, the building code (IRC Appendix Q) and zoning govern minimum dwelling standards.
Because Texas counties have no zoning power, unincorporated Brazoria County cannot impose a minimum square footage or ban tiny homes; however, a permanent tiny home on land still needs an approved on-site septic system (OSSF, H&S Ch. 366), must comply with subdivision platting (LGC Ch. 232), and must meet floodplain elevation on this Gulf coast. A tiny home on wheels is generally treated as an RV, not a dwelling. Inside a city, tiny homes must meet the adopted International Residential Code (including Appendix Q for units under 400 square feet) and the zoning district's dwelling standards.
County can act on unpermitted septic, unplatted subdivision, or floodplain violations; city zoning/building enforcement handles minimum-dwelling and permit violations.
