Subd. 1. Intent. A non-conforming sign is any sign that was legally established and maintained in compliance with the provisions of all applicable laws in effect at the time of original installation but that does not now comply with the provisions of this chapter. It is the intent of this chapter to recognize that the eventual elimination of signs that do not comply with the provisions of this chapter is as important as the prohibition of new signs that would violate these standards.
Subd. 2. General Requirements. A non-conforming sign may not be:
1. Changed to another non-conforming sign;
2. Expanded;
3. Re-established after a business discontinued for more than one year; or
4. Re-established after damage or destruction of more than 50% of its value, as determined by the Building Official, and no building permit has been applied for within 180 days of when the damage occurred.
Subd. 3. Amortization. After the date of enactment of this chapter, non-conforming signs located within any zoning district shall be brought into compliance with this chapter if said sign is to be expanded.
Subd. 4. Maintenance and Repair. Non-conforming signs and sign structures may be maintained and repaired.
