15.20.290: NONCONFORMING SIGNS:
   A.   Changes which reduce the overall degree of nonconformity (i.e., cabinet or copy size/overall height reductions, sight triangle corrections, or encroachments on the public right-of- way) shall be permitted as long as the original structure has not become structurally unsound. Sign face changes and routine maintenance not involving structural alterations or cabinet removal shall be permitted, except under circumstances set out in the following subsection.
   B.   Reserved.
   C.   Legal nonconforming signs and sign structures shall be allowed to remain in place except under the following circumstances, any one of which will require the removal of the sign and compliance with this chapter for any other sign:
      1.   If a sign cabinet, face, or structure is removed, refurbished, replaced, or relocated without prior approval by the Planning and Development Services staff, or if the approved change(s) to the cabinet, face or structure has not been completed within ninety (90) days of permit issuance.
      2.   If the sign copy has not correctly identified a site or business for over one hundred eighty (180) days. Any person contesting this determination by City staff must provide proof that the one hundred eighty (180) day maximum has not elapsed.
      3.   If a new business or use has moved to the site and refurbishing the signage exceeds fifty percent (50%) of the replacement cost. Any person contesting this determination by City staff must provide proof of replacement cost in the form of a written estimate from a licensed sign contractor.
      4.   If a sign has been improperly maintained or has become structurally unsound as determined by the City Building Department.
      5.   If additional signage, of any type, is proposed for the site in question.
      6.   If any change is made to window or painted wall signs. (Ord. 3008, 2018: Ord. 2915, 2012: Ord. 2702 §§ 6, 7, 8, 2002: Ord. 2349, 1991)
