ADU rules in El Paso County, TX — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Texas counties cannot zone, so unincorporated El Paso County has no ADU or second-dwelling zoning ordinance. What actually applies to a new accessory dwelling is a septic (OSSF) permit, a floodplain development permit, and subdivision platting through the county Planning and Development Department.
El Paso County does not regulate accessory dwelling units through zoning; Texas counties have no zoning authority, and the county FAQ confirms there are no zoning requirements in the unincorporated area (except near Fabens Airport or the Historic Mission Trail). Cities regulate ADUs inside their limits. If the lot is not on public sewer, an on-site sewage facility (septic) permit is required from the El Paso County OSSF Program of Public Works under Health and Safety Code Chapter 366 and 30 TAC Chapter 285. Approved grading and drainage plans are required before construction, a floodplain permit applies in a mapped flood zone, and dividing land requires a plat under Local Government Code Chapter 232.
Building a second dwelling without a septic (OSSF) permit, approved grading and drainage plans, or a floodplain permit in a flood zone can bring stop-work action, enforcement under the county OSSF order, and denial of an address or utility service.
