How to verify zoning in San Antonio.
San Antonio zoning is governed by the Unified Development Code, which pairs a base district with frequently applied overlays — Neighborhood Conservation, Historic, Airport Hazard, and the Edwards Aquifer Recharge Zone. The recharge zone in particular adds impervious-cover and water-quality review that the base district does not disclose.
