29.40.020 Dangerous Structures.
Any structure that has any or all of the following conditions or defects to the extent that life, health, property, or safety of the public or the structure’s occupants are endangered, is deemed to be a dangerous structure and such condition or defects must be abated pursuant to Sections 29.60.050 and 29.60.080 of this Title.
- 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 1-1/2 times the working stress or stresses allowed in the Oregon Structural Specialty Code and Fire and Life Safety Code for new buildings of similar structure, purpose, or location.
- B. Weakened or unstable structural members or appendages.
- 1. 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 State Structural Specialty Code and Fire and Life Safety Code for new buildings of similar structure, purpose, or location; or
- 2. Whenever appendages including parapet walls, cornices, spires, towers, tanks, statuaries, or other appendages or structural members that are supported by, attached to, or part of a building, and that are in a deteriorated condition or otherwise unable to sustain the design loads that are specified in the Oregon State Structural Specialty 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.
- 1. Whenever any portion of a structure is wrecked, 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; or
- 2. 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 Structural Specialty 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 State Structural Specialty Code and Fire and Life Safety Code for such buildings.
- E. Insufficient strength or fire resistance. Whenever any structure that, whether or not erected in accordance with all applicable laws and ordinances:
- 1. Has in any non-supporting 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; or
- 2. 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.
- This subsection does not apply to strength required to resist seismic loads. For application of seismic requirements see Chapter 24.85.
- F. Risk of failure or collapse.
- 1. Whenever any portion or member of appurtenance thereof is likely to fail, or to become detached or dislodged, or to collapse and injure persons or damage property; or

- d. The deterioration, decay, or inadequacy of its foundation.
- G. Excessive damage or deterioration.Whenever the structure exclusive of the foundation:
- 1. Shows 33 percent or more damage or deterioration of its supporting member or members;
- 2. 50 percent damage or deterioration of its non-supporting members; or
- 3. 50 percent damage or deterioration of its enclosing or outside wall coverings.
- 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;

- 2. For more than 90 days after issuance of a permit for a foundation for a structure, where the structure is not placed on an approved foundation.
- J. Fire hazard. 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 fire-resistive construction; or faulty electric wiring, gas connections, or heating apparatus.
