Land Use and Zoning Texas 3 Minutes Read · published February 05, 2026 Flag of Texas

In San Antonio, Texas, sign size, height and illumination limits are set by the City’s land-use regulations and permitting process. Rules vary by zoning district, sign type (wall, monument, pole, awning, electronic) and whether a sign is on-premises or off-premises. For the controlling ordinance text and zoning-specific tables consult the City of San Antonio Unified Development Code sign provisions and maps for your parcel Unified Development Code - sign rules[1].

Sign size, height and illumination: overview

San Antonio controls sign area, maximum height, setback and illumination intensity by combining zoning district standards with sign type definitions. Typical regulatory features include:

  • Definitions for sign area and height measured to the highest attached point.
  • Zoning-district tables that set maximum sign area per frontage or lot size.
  • Illumination rules that may restrict flashing, changeable copy, and require shielding to limit glare into rights-of-way or residences.
  • Special controls for freeway-facing, multi-tenant, and electronic message centers including minimum separation and allowed hours.
Always confirm the zoning for your property before ordering a sign.

Penalties & Enforcement

Enforcement of sign rules is handled by the City’s permitting and code-compliance functions within Development Services and related enforcement teams. Monetary fines and administrative penalties for sign violations are governed by the City code and municipal enforcement procedures; specific fine amounts are not specified on the cited page.
