Garage conversion rules in Cameron County, TX — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Cameron County has no ordinance on converting a garage to living space, since Texas counties cannot zone or enforce a building code in unincorporated areas. If you live inside a city, that city's zoning and building codes govern the conversion. County-wide, only septic capacity and floodplain rules may apply.
Converting a garage into a bedroom, apartment, or office is a zoning-and-building-code question, and Texas counties have neither power outside city limits. So there is no Cameron County garage-conversion permit or standard for unincorporated property. Inside Brownsville, Harlingen, San Benito, or another city, that city's code controls occupancy, egress, and parking. County-wide, adding a bathroom or kitchen means the on-site septic system (OSSF, H&S Ch. 366) must have capacity, and any structural work in a mapped flood zone needs a county floodplain development permit. Confirm requirements with your city; for unincorporated land, contact County Health (septic) and Engineering (floodplain).
No county conversion penalty. Overloading a septic system or building in a floodplain without the county permit can bring health-department and NFIP enforcement. City conversions without a permit are cited by the city.
