ADU rules in Nueces County, TX — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Nueces County cannot zone. Texas counties have no general zoning power, so unincorporated Nueces County sets no ADU rules. Inside a city like Corpus Christi, the city's Unified Development Code (Sec. 5.3.2.A) governs accessory dwelling units.
Texas counties lack authority to adopt zoning or use regulations in unincorporated areas, so there is no county ADU permit, size cap, or owner-occupancy rule outside a city. If your property lies inside Corpus Christi, Robstown, or Port Aransas, that city's code applies. Corpus Christi regulates accessory dwelling units under Unified Development Code Section 5.3.2.A (permitted districts, size, and parking). Unincorporated property owners still need a septic (OSSF) permit under Texas Health & Safety Code Chapter 366 and any required building permit; platting for a new lot follows Local Government Code Chapter 232.
No county zoning fine exists. Inside a city, unpermitted ADU construction is a municipal code violation. Unincorporated septic violations are enforced under H&S Code Ch. 366 by the county health department.
