San Antonio, TX Zoning

The source set confirms that zoning, land development, and permitting are centralized through the City’s Development Services system, but the research package only contains partial district and use detail rather than the full UDC use and dimensional tables.

Recent Zoning Changes
The current online UDC was updated March 24, 2026 and codified through Ordinance 2025--09-04-0580, effective September 4, 2025. The Municode site also lists at least one adopted but not yet codified ordinance from April 16, 2026 concerning detention facilities. The provided materials also include an older 2018 proposed ordinance for R-3, R-2, and R-1 districts, but that document should be treated cautiously because it is labeled proposed/updated rather than clearly shown as currently codified law.
