Tiny home rules in Cameron 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.
Unincorporated Cameron County has no tiny-home zoning rule; Texas counties cannot set minimum house size or density outside city limits. A tiny home on a foundation still needs an approved septic (OSSF) system and a platted lot; on wheels it is treated as an RV.
Because Texas counties have no zoning power, Cameron County cannot ban tiny homes, set a minimum square footage, or require a special zoning permit in unincorporated areas. The real county controls are the on-site sewage facility (OSSF/septic) permit under Health & Safety Code Ch. 366 and 30 TAC 285, and subdivision platting under LGC Ch. 232 with the Rio Grande Valley Model Subdivision Rules (adequate water, sewer, and road access). A tiny home on wheels is generally an RV/travel trailer, not a permanent dwelling, and city or park rules may govern where you park it. Inside a city, that city's zoning controls tiny homes. Confirm with your city or with County Health/Engineering.
No county tiny-home penalty. Placing a permanent dwelling without an approved septic permit or on an unplatted lot can bring county civil enforcement under H&S Ch. 366 and LGC Ch. 232.
