ADU rules in Mission, TX β also called accessory dwelling unit regulations or granny flat ordinances β cover setbacks, owner-occupancy, parking, and permit requirements.
No statewide ADU mandate in Texas. Mission's zoning code (Appendix A) governs ADU allowances. Contact Mission Planning & Zoning to verify what's permitted in your district.
Mission's zoning code permits accessory dwelling units (ADUs) in single-family residential zones. ADUs may be attached (converted garage, addition) or detached structures. Size is typically limited to 800-1,200 square feet or 50% of the primary dwelling's floor area, whichever is less. Setback requirements match those for accessory structures (typically 5 feet from side and rear property lines). Owner occupancy of either the primary or accessory unit may be required. ADUs must meet current building code, include independent kitchen and bathroom facilities, and comply with county utility connection requirements. Texas state legislation may further shape local ADU rules.
Unpermitted ADUs face stop-work orders and removal or legalization requirements. Fines of $500β$2,000 apply for unpermitted construction. Properties with illegal ADUs may face title issues at sale.
