§ 90.21 BUILDING MAINTENANCE AND APPEARANCE.
   (A)   Declaration of nuisance. Buildings, fences and other structures that have been so poorly maintained that their physical condition and appearance detract from the surrounding neighborhood are declared to be public nuisances because they (a) are unsightly, (b) decrease adjoining landowners and occupants’ enjoyment of their property and neighborhood, and (c) adversely affect property values and neighborhood patterns.
   (B)   Standards. A building, fence or other structure is a public nuisance if it does not comply with the following requirements:

         (a)   Any one wall or other flat surface; or
         (b)   All door and window moldings, eaves, gutters, and similar projections on any one side or surface.
      (3)   No glass, including windows and exterior light fixtures, may be broken or cracked, and no screens may be torn or separated from moldings.
      (4)   Exterior doors and shutters must be hung properly and have an operable mechanism to keep them securely shut or in place.
      (5)   Cornices, moldings, lintels, sills, bay or dormer windows and similar projections must be kept in good repair and free from cracks and defects that make them hazardous or unsightly.
      (6)   Roof surfaces must be tight and have no defects that admit water. All roof drainage systems must be secured and hung properly.
