20.220 Existing Signs.
All signs, billboards, or other advertising structures which do not conform to the regulations of this Chapter, but which were constructed in compliance with previous rules and regulations, shall be regarded as nonconforming and may be continued, pursuant to Section 20.220 except that:
A. The provisions of this section shall not be construed as authorizing the continued maintenance of any sign, billboard or other advertising structure which is required to be removed by the provisions of Section 20.160.
B. No such nonconforming sign originally erected without a permit shall be allowed to continue more than ninety (90) days from the effective date of this Section, unless the owner shall provide such proof as is necessary to establish the date when said sign was erected, and shall apply for a permit hereunder. Said permit shall be granted if it appears that said sign was constructed in compliance with the rules and regulations effective at the time it was erected, and shall thereafter be treated as a nonconforming sign.
