Permits are required for all permanent commercial signage. On the permit application (PDF), make sure to fill out the second page of the application which requests specific details for proposed signage.
In addition to the Permit Application, please submit 2 copies of all sign related information (depiction, dimensions, material, etc.). For all monument signs, also submit 2 copies of a site plan and structural engineering.
All temporary signs (banners, reader boards, sandwich boards) require a temporary sign permit.
