Professional Signage Solutions for Palo Alto Businesses

Snapshot: Palo Alto's Sign‑Permit Rules
All exterior signs in Palo Alto—wall‑mounted, projecting, ground, awning, illuminated, or fabric—require a Sign Permit under Chapter 16.20 (Signs) of the Palo Alto Municipal Code and must undergo Architectural Review.
Licensed Contractors
Although property owners may submit applications themselves, Sign Permits typically process more quickly when filed by a CSLB‑licensed C‑45 sign contractor or C‑10 electrician through Palo Alto's all‑digital permit platform.
Business Registration
No Sign Permit can issue without a valid Palo Alto Business Registration Certificate. All fixed‑location businesses must file annually for a Business Tax Certificate via the City's Licenses & Permits portal.
