The San Antonio Unified Development Code, in plain English

San Antonio's development code governs how land here is subdivided and built on — zoning districts and what each allows, subdivision and platting, lot and building standards, and parking. This is our working explanation of those rules, with the exact code sections cited so you can check us.

We're LotCodex. We read the San Antonio Unified Development Code closely, section by section, and turn it into plain-language answers for anyone planning a build in San Antonio — builders, architects, and homeowners alike. Each page cites the section it's drawn from and carries the date we last checked it.

This is how the code reads; confirm with the city — or ask a builder who's actually pulled this permit in San Antonio. The authoritative text is the San Antonio Unified Development Code.
