Temporary Sign Permits and Regulations

Temporary Event and Grand Opening Permit Application


All commercial, industrial, public and quasi-public uses and mixed-use developments (commercial combined with multi-family residential) will be allowed to display temporary event signage with a valid permit. Permit fees will vary depending upon the types of signs displayed.

A temporary event sign is a display device, constructed of cloth, canvas, light fabric, cardboard, wall board or other light materials, with or without frames, intended to be displayed for a limited period of time only. Temporary event signage includes but is not limited to balloons, banner, flags, pennants/streamers, wind animated devices, inflatable statuary, rigid portable signs, portable reader-boards, and searchlights. Other types of display devices will require the approval of the Development Services Director.

Signage for a grand opening event will be permitted for a thirty-day period and will only be issued to new business or existing business relocating to an entirely new location. Temporary event signage will be permitted for thirty days with a maximum of four temporary event sign permits issued to a business per calendar year. A fifteen-day separation period will be required between the end of one event period and the start of another permit period.
