For the purpose of this chapter, any building or structure which has any or all of the conditions or defects hereinafter described shall be deemed a dangerous building:
(a) Whenever any door, aisle, passageway, stairway or other means of exit is not of sufficient width or size, or it is so arranged as to provide safe and adequate means of exit, in case of fire or panic, for all persons housed or assembled therein who would be required to, or might, use such door, aisle, passageway, stairway or other means of exit.
(b) Whenever the stress in any materials, member or portion thereof, due to all dead and live loads, is more than one and one-half times the working stress or stresses allowed in the building code.
(c) Whenever any portion thereof has been damaged by earthquake, wind, flood, or by any other cause, in such a manner that the structural strength or stability thereof is appreciably less than it was before such catastrophe and is less than the minimum requirements of this code for a new building or similar structure, purpose or location.
(d) Whenever any portion or member or appurtenance thereof is likely to fall, or to become detached or dislodged, or to collapse and thereby injure persons or damage property.
(e) Whenever any portion of a building, or any member, appurtenance or ornamentation on the exterior thereof is not of sufficient strength or stability, or is not so anchored, attached or fastened in place so as to be capable of resisting a wind pressure of one-half that specified in the building code without exceeding the working stresses permitted in the building code.
(f) Whenever any portion thereof has settled to such an extent that walls or other structural portions have materially less resistance to winds or earthquakes than is required in the case of new construction.
(g) Whenever the building or structure, or any portion thereof, because of dilapidation, deterioration, decay, faulty construction, or because of the removal or movement of some portion of the ground necessary for the purpose of supporting such building or portion thereof, or some other cause, is likely to partially or completely collapse, or some portion of the foundation or underpinning is likely to fall or give way.
(h) Whenever, for any reason whatsoever, the building or structure or any portion thereof, is manifestly unsafe for the purpose for which it is used.
(i) Whenever the exterior walls or other vertical structural members list, lean or buckle to such an extent that a plumb line passing through the center of gravity does not fall inside the middle third of the base.
(j) Whenever the building or structure, exclusive of the foundation, shows thirty-three percent or more of damage or deterioration to the member or members, or fifty percent of damage or deterioration of a nonsupporting enclosing or outside wall covering.
(k) Whenever the building or structure has been so damaged by fire, wind, earthquake or flood, or has become so dilapidated or deteriorated as to become an attractive nuisance to children who might play therein to their danger, or as to afford a harbor for vagrants, criminals or immoral persons, or as to enable persons to resort thereto for the purpose of committing nuisance or unlawful or immoral acts.
(l) Any building or structure which has been constructed, or which now exists or is maintained in violation of any specific requirement or prohibition, applicable to such building or structure, of the building regulations of this city, as set forth in the building code, or of any provisions of Title 15 of this code relating to the prevention of fire, when so determined and reported by the fire marshal, or of any law or ordinance of this state or city relating to the condition, location or structure of buildings.
(m) Any building or structure which, whether or not erected in accordance with all applicable laws and ordinances, has in any nonsupporting part, member or portion, less than fifty percent, or in any supporting member less than sixty-six percent of the strength, fire-resisting qualities or characteristics or weather resisting qualities or characteristics required by law or ordinance in the case of a newly constructed building of like area, height and occupancy in the same location.
(n) Whenever a building or structure, used or intended to be used for dwelling purposes, because of dilapidation, decay damage, or faulty construction or arrangement, or otherwise, is unsanitary or unfit for human habitation or is in a condition that is likely to cause sickness or disease, when so determined by the health officer, or is likely to work injury to the health, safety or general welfare of those living within.
(o) Whenever the building or structure, used or intended to be used for dwelling purposes, has light, air, and sanitation facilities inadequate to protect the health, safety, or general welfare of persons living within.
(p) Whenever any building or structure by reason of obsolescence, dilapidated condition, deterioration, damage, electric wiring, gas connections, heating apparatus, or other cause, is in such condition as to be a fire hazard and is so situated as to endanger life or other buildings or property in the vicinity or provide a ready fuel supply to augment the spread and intensity of fire arising from any cause.
