Overview of Sign Permit Process

Permit requirements depend on sign type, size, illumination, and placement. Typically the applicant must submit a completed application, scaled drawings, site plan or elevation, and proof of property ownership or landlord authorization. Review may involve Building, Zoning, and Planning staff; structural calculations are required for certain freestanding or large signs.

  • Prepare drawings and owner authorization.
  • Submit application and pay fees.
  • Schedule inspections after installation.
Confirm which department issues sign permits before paying fees.
