A. 
Buildings and parts thereof shall be maintained so as to be capable of sustaining safely their own weight and the loads to which they may be subject.
B. 
Buildings shall be maintained so that loads are transmitted to the soil without undue differential settlement, unsafe deformation or movement of the building or of any structural part.
C. 
Buildings shall be maintained so that protection is provided for all structural members which may become structurally unsound if left unprotected. Causes of such deterioration include, among others, action of freezing and thawing, dampness, corrosion, wetting and drying, and termites and other destructive insects.
D. 
Buildings built in soil which is water-bearing at any season of the year shall be maintained so that ground- and surface water will not penetrate into basements and cellars.
A. 
Foundation walls shall be maintained so as to be structurally sound and to prevent entrance of moisture, termites and vermin. Such protection shall, where necessary, consist of shoring, subsoil drains at footings, grouting of masonry cracks and waterproofing of walls and joints, and other approved means.
B. 
Exterior walls and wall components shall be maintained so as to prevent deterioration due to the elements and destructive insects. Such maintenance shall consist of replacement, repair or painting of walls, copings and flashings, waterproofing of joints, waterproof coatings, installation or repair of termite shields and poison treatment of soil, or other suitable means.
C. 
Exterior doors, windows, skylights and similar openings shall be maintained weathertight by means of caulking, glazing and replacement of defective parts, or other suitable means.
D. 
Exterior stairs, porches, entrance platforms and fire escapes, and the railings thereon, shall be maintained so as to be structurally sound. Such maintenance shall consist of replacement, repair or painting, or other suitable means.
E. 
Roofing shall be maintained in watertight condition so as to prevent leakage into the building. Such maintenance shall consist of roofing, flashings and waterproof coatings, or other suitable means.
A. 
Crawl spaces shall be maintained free of moisture, and the flow of air from such spaces into walls above shall be effectively barred so as to prevent deterioration of structural members. Such provisions shall consist of maintenance of openings in foundation walls to provide adequate circulation of air in the crawl space, covering the ground in the crawl space with a moisture barrier, installation of drains outside the structure if the crawl space is below surrounding grade, blocking openings in stud walls to prevent flow of air and moisture into walls, frequent destruction of termite tubes from the soil to wood floor members above, poison treatment of soil or other suitable means.
B. 
Structural members shall be maintained so as to be structurally sound. Such protection shall consist of shoring, reinforcement or repair, where necessary, frequent destruction of termite tubes or other appropriate means.
C. 
Chimneys and flues shall be maintained so as to be structurally sound and to prevent leakage of gases into the structure. Such maintenance shall consist of clearing flue stoppages, sealing open joints, preparing masonry where necessary, and other approved means.
D. 
Ceilings and walls, floors and stairways shall be maintained so that parts which become loose or defective do not constitute a hazard to occupants. Such maintenance shall consist of replacing or repairing loose or defective sections.
E. 
Toilet room and bathroom floors shall be maintained so as to prevent leakage of water through the floor, under normal conditions of use and floor washings, and resultant deterioration or defects in structural members and ceilings below. Maintenance shall consist of repairs which effectively provide the moisture resistant qualities required for the particular floor.
