Signs and Advertising Arizona 3 Minutes Read ยท published March 08, 2026 Flag of Arizona

San Tan Valley, Arizona property owners and advertisers must follow county and state rules for billboards, freestanding signs, and LED displays. This guide summarizes how sign size, placement, illumination and inspections are regulated, who enforces the rules, where to apply for permits, and what to do if you receive a notice or violation. Because San Tan Valley is unincorporated, Pinal County standards and state outdoor-advertising controls apply; review permits and variance options before installing or operating large or illuminated signs.

Check county zoning before installing illuminated signs.

Overview of Limits

Typical rules that apply in San Tan Valley address:

  • Placement and setbacks from property lines and public rights-of-way.
  • Maximum sign area and height for commercial and billboard-class structures.
  • Illumination and LED change-rate restrictions to prevent unsafe distractions.
  • Permit and renewal timelines, and requirements for site plans and engineering where required.

For state-controlled highways and interstates, Arizona Department of Transportation standards for outdoor advertising and permitting also apply to billboards and off-premise signs.
