Understanding San Antonio zoning districts
San Antonio's zoning is built around a handful of base districts. Residential zones (often R-1, R-2, RM-1, etc.) control single-family and multi-family housing with different lot size, setback, and height limits. Commercial zones (C-1, C-2, C-3) permit retail, office, and mixed-use. Industrial zones (I or M) cover manufacturing, warehousing, and heavy uses. Mixed-use and transit-oriented zones layer housing above commercial. Buildability™ returns your exact district and decodes what it means for your specific San Antonio parcel.
Overlays and the things that trip people up
Texas state law often overrides or supplements San Antonio zoning — especially on ADUs, density bonuses, and ministerial approvals. A San Antonio ordinance might say one thing while state law says another; the state law usually wins. Buildability™ reads both layers and tells you what actually applies.
