(1)
Generally. No premises shall contain any dangerous building or structure as described in this title. Once identified and determined to be dangerous by the Building Official, all such buildings, premises, or structures shall be repaired or demolished.
(2)
Definition. A dangerous building, premises, or structure shall be considered to exist whenever any premises, building, structure, or portion thereof meets any of the following criteria to the extent that the life, health, property, or safety of the public or the building, structure, or premises’ occupants are unreasonably endangered:
(a)
High Loads. Whenever the stress in any materials, member, or portion of a structure, due to all dead and live loads, is more than one and onehalf times the working stress or stresses allowed in the Oregon Building Code and Fire and Life Safety Code for new buildings of similar structure, purpose, or location.
(b)
Weakened or Unstable Structural Members or Appendages.
(i)
Whenever any portion of a structure has been damaged by fire, earthquake, wind, flood, or by any other cause, to such an extent that the structural strength or stability is materially less than it was before such catastrophe and is less than the minimum requirements of the Oregon Building Code and Fire and Life Safety Code for new buildings of similar structure, purpose, or location; and/ or
(ii)
Whenever appendages including parapet walls, cornices, spires, towers, tanks, statuaries, signs, or other appendages or structural members which are supported by, attached to, or part of a building, are in a deteriorated condition or otherwise unable to sustain the design loads which are specified in the Oregon Building Code and Fire and Life Safety Code.
(c)
Buckled or Leaning Walls, Structural Members. 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 one-third of the base.
(d)
Vulnerability to Earthquakes, High Winds.
(i)
Whenever any portion of a structure has wracked, warped, buckled, or 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 similar new construction; and/or
(ii)
Whenever any portion of a building, or any member, appurtenance, or ornamentation of 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 of that specified in the Oregon Building Code and Fire and Life Safety Code for new buildings of similar structure, purpose, or location without exceeding the working stresses permitted in the Oregon Building Code and Fire and Life Safety Code for such buildings.
(e)
Insufficient Strength or Fire Resistance. Whenever any structure which, whether or not erected in accordance with all applicable laws and ordinances:
(i)
Has in any nonsupporting part, member, or portion, less than 50 percent of the strength or the fire-resisting qualities or characteristics required by law for a newly constructed building of like area, height, and occupancy in the same location.
(ii)
Has in any supporting part, member, or portion less than 66 percent of the strength or the fire-resisting qualities or characteristics required by law in the case of a newly constructed building of like area, height, and occupancy in the same location.
(iii)
This subsection does not apply to strength required to resist seismic loads. For application of seismic requirements see the Oregon Building Code.
(f)
Risk of Failure or Collapse.
(i)
Whenever any portion or member or appurtenance thereof is likely to fail, or to become detached or dislodged, or to collapse and thereby injure persons or damage property.
(ii)
Whenever the structure, or any portion thereof, is likely to partially or completely collapse as a result of any cause, including, but not limited to:
(g)
Excessive Damage or Deterioration. Whenever the structure, exclusive of the foundation:
(h)
Demolition Remnants On-Site. Whenever any portion of a structure, including unfilled excavations, remains on a site for more than 30 days after the demolition or destruction of the structure.
(i)
Lack of Approved Foundation.
(j)
Fire Hazard.
(i)
Whenever any structure is a fire hazard as a result of any cause, including but not limited to: dilapidated condition, deterioration, or damage; inadequate exits; lack of sufficient fireresistive construction; vegetation overgrowth; faulty electric wiring, gas connections, or heating apparatus; storage or keeping of combustibles; or any other cause that is determined by the Fire Marshal or Building Official to be a fire hazard.
(ii)
Whenever any door, aisle, passageway, stairway, or other means of exit is not of sufficient width or size or is not so arranged as to provide safe and adequate means of exit in case of fire or panic.
(iii)
Whenever the walking surface of any aisle, passageway, stairway, or other means of exit is so warped, worn, loose, torn, or otherwise unsafe as to not provide safe and adequate means of exit in case of fire or panic.
(k)
Other Hazards to Health, Safety, or public Welfare.
(i)
Whenever, for any reason, the structure, building, or premises, or any portion thereof, is manifestly unsafe for the purpose for which it is currently being used.
(ii)
Whenever a structure, building, or premises has any of the conditions or defects to the extent that life, health, property, or safety of the public or its occupants are endangered.
(l)
(m)
Drug Lab Property. Is currently listed as “unfit for use” by the state of Oregon due to toxic contamination resulting from illegal drug manufacturing.
(n)
Violations of Codes, Laws. Whenever any structure, building, or premises has been constructed, exists, or is maintained in violation of any specific requirement or prohibition applicable to such structure provided by the building regulations of this City, as specified in the Oregon Building Code, Fire and Life Safety Code, or any law or ordinance of this state or City relating to the condition, location, or structure of buildings.
