§ 20-6. Property maintenance standards.

All developed real property in the city shall be maintained at a level not less than the following standards:

(a) Condition of structures. Structures shall not be partially destroyed, abandoned, unsecured, or permitted to remain in a state of partial construction for more than 30 days. Buildings or structures shall not be boarded up for a period in excess of 10 days without a valid demolition or building permit on file, except in compliance with section 20-7.

(b) Building exteriors and roofs. Exterior building surfaces and roofs shall be maintained free of significant surface cracks, missing materials, warping, dry rot which either threaten the structural integrity, or result in a dilapidated, decaying, disfigured, or partially ruined appearance.

(e) Graffiti. All structures, equipment, walls, and fencing on the property shall be maintained free of graffiti pursuant to Chapter VII½ of Title 11.

(3) Exception: All existing trash dumpsters shall be affixed with a lid and screened from public view by a trash enclosure or other acceptable manner under the direction of the planning division.

The zoning administrator may waive this requirement, if he/she determines that the loss of onsite parking shall create a hardship for the site, subject to review pursuant to Chapter IX of Title 2. The location of any trash enclosure or screen on the site as required by this section shall be approved by the planning division.
