This chapter shall not apply to any items that were being legally displayed or placed on sidewalk as of March 1, 1986 or to any lights legally and permanently in place as of March 1, 1986. If the display or placement on the sidewalk of any item or any light was illegal as of March 1, 1986, only because no revocable encroachment permit had been issued, the display or placement shall be deemed legal for purposes of this section if a successful application for revocable encroachment permit was filed within thirty (30) days after March 1, 1986. (Ord. 2005-021 § 1, 2005; Prior code § 3.19.273)
