How to Apply for Different Kinds of Sign Permits

For permanent signs (freestanding or attached to the building wall), apply using the Online Portal. Temporary signs (such as lawn signs and A-frames) do not require an official permit, just a simple registration form to acknowledge the rules (register online). If you are a non-profit group wanting to display a community banner on one of the city-owned structures, reserve your time and space on the city's rentals page.
