§ 92.22 FOUNDATIONS, EXTERIOR WALLS AND SURFACES, ROOFS.
   Every foundation, chimney, exterior wall and surface and roof shall be weathertight, watertight, rodent proof and insect proof, and shall be kept in a workmanlike state of maintenance and repair.
   (A)   The foundation elements shall support the building at all points.
   (B)   Every exterior wall shall be free of holes, breaks, loose or rotten boards or timbers and any other condition which might admit rodents, rain or dampness to the interior portions of the walls or to the interior space of the dwelling.
   (C)   The roof shall be tight and have no defects which admit rain or other forms of moisture. Roof drainage shall be such that it prevents rain water from causing dampness to the walls.
   (D)   All exterior surfaces shall be of a material manufactured and processed specifically for use in a weather-exposed location, including roofing, exterior painted wood, masonry, exposed redwood and other naturally suitable materials. Exterior walls shall be maintained and kept free from dilapidation, including those conditions caused by extensive cracks, tears or breaks and by extensively deteriorated plaster, stucco, brick, wood or other materials or combinations of materials.
   (E)   The exposed surface of exterior walls on a building above ground level shall be maintained in good repair so as to provide both sufficient covering and sufficient protection of true surface underneath against its deterioration. Without limiting the generality of this section, an exposed surface of a building shall be deemed not to be in a workmanlike state of maintenance and not to be in good repair if either or both of the following conditions exist:
      (1)   The painted surface area is blistered, cracked, flaked, scaled or chalked away, and such conditions extend over more than 25% of the surface area of any plane or wall or other area, including porch trim, cornice members, porch railings and such other areas;
      (2)   More than 10% of the pointing of any masonry chimney or more than 25% of the pointing of any masonry wall is loose, has fallen out or otherwise does not exist.
   (F)   Any exterior surface or plane required to be repaired under the provisions of this section shall be repaired in its entirety to make it weathertight, watertight and rodent proof.
