2. Damage to any portion of a building by earthquake, wind, fire, flood or by any other cause, in such a manner that the structural stability, or strength thereof, is appreciably less than the minimum requirements set forth in existing codes and ordinances for a new building or structure of similar size, construction, location and use;

3. Likelihood of any portion or member or appurtenance of a building to fall, or become dislodged or detached, or to collapse, and thereby cause bodily injury or property damage;

4. Settling of any building or portion thereof, to such an extent that walls or other structural portions have been displaced or distorted and rendered structurally unstable or dangerous, or that the basic foundation of such element has been impaired;

5. The building or structure, or any portion thereof, because of dilapidation, deterioration, decay, faulty construction or because of the removal or removement of some portion of the ground necessary for the purpose of supporting such building or structure or portion thereof, or other cause is likely to partially or completely collapse, or some portion of the foundation or underpinning is likely to fall or give way;

7. The building or structure, exclusive of the foundation, shows thirty-three (33) percent or more of damage or deterioration to the supporting structural members, or fifty (50) percent of damage or deterioration of a nonsupporting outside wall or covering;

8. The building or structure has been so damaged by fire, wind, earthquake, flood or has become so dilapidated or deteriorated, from any cause whatsoever, 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 a nuisance or unlawful or immoral act.

1. Deteriorated, crumbling or loose plaster;

All buildings or portions thereof which are not provided with fire-resistive construction or fire-extinguishing systems or equipment required by local codes and ordinances except those buildings or portions thereof which conform with all applicable laws at the time of their construction and whose fire-resistive integrity and fire-extinguishing systems or equipment have been adequately maintained and improved in relation to any increase in occupant load, alteration or addition or any change in occupancy.

E. Fire Hazards. Any building or portion thereof, device, apparatus, equipment, combustible waste, or vegetation, which is such a condition as is likely to cause a fire or explosion or provide a ready fuel to augment the spread and intensity of fire explosion arising from any cause.

F. Hazardous or Unsanitary Premises. Those premises on which an accumulation of weeds, vegetation, junk, dead organic matter, debris, garbage, offal, rat harborages, stagnant water, combustible materials and similar materials or conditions constitute fire, health, or safety hazards or constitute a nuisance as defined by city ordinance.

H. Hazardous Wiring.

1. Exposed electric wire or wire with deteriorated or damaged insulation;

2. Switch and outlet plates missing or improperly fastened;
