  • Any sign proposed for construction or placement within the City must obtain a sign permit under Section 2.1 unless specifically exempted by Section 2.2; the permit application must include scaled drawings, existing sign inventory on the site, structural details, landscaping plan if required, and lighting/electrical information.
  • Requests for increases in maximum allowable sign height, area, or number beyond what is permitted in the regulations (other than minor modifications) must be processed through approval of a Final Planned Unit Development (PUD) under Title 17, using the sign‑specific review criteria in Section 2.3.1.
  • Minor modifications to any sign standard (including up to 10% adjustments to sign area or height) may be approved administratively by the Department of Planning and Building Safety as a Minor Impact Variance under Section 17.52.050, based on the findings in Section 2.3.2.
  • Electronic message centers other than variable pricing signs for gasoline stations and certain display signs in Commercial and Mixed‑Use areas are allowed only if expressly authorized as part of an approved Final PUD plan, which must include specific design, location, and operational standards for the electronic message center.
  • Kiosks are permitted only when expressly authorized in an approved Final PUD plan or, in some cases, via Special Review Use (SRU); the PUD or SRU approvals must specify kiosk design, construction, maintenance, operation, and any illumination.
  • Canopy signs in vehicular areas are allowed only in Commercial and Mixed‑Use areas when a canopy in a vehicular area is expressly authorized in an approved Final PUD plan, with PUD standards covering canopy and sign design.
  • Display signs oriented to a drive‑through lane are allowed in Commercial and Mixed‑Use areas only if a drive‑through is expressly authorized in an approved Final PUD plan; any electronic message center used in such a display sign must comply with Section 3.4.
  • A sign designated as an Iconic Sign must be reviewed by the Department of Planning and Building Safety and then approved by the Historic Preservation Commission and City Council; any subsequent change requiring a permit also requires Historic Preservation Commission review if inconsistent with the original Iconic Sign findings.
  • A sign designated as a Landmark Sign must meet historic landmark criteria in Section 15.36.050 and be approved by the Historic Preservation Commission and City Council; any permitted change to a Landmark Sign also requires an Alteration Certificate under Section 15.36.110 before work begins.
  • All permanent sign installations must meet adopted building and electrical code requirements; electrical signs must bear an approved UL label or receive State electrical inspector approval at final inspection.
  • A coordinated sign program (sign program) is contemplated as a design package identifying a unified theme for all signs associated with a building, including color, lettering style, material, and placement, although the code does not mandate when a sign program is required for all sites.
  • Where Planned Unit Development (PUD) regulations for a property include specific sign allowances or restrictions that directly conflict with the Sign Code, the approved PUD standards govern to the extent of the conflict, unless the property owner elects to fully comply with the Sign Code instead in the area of conflict.
