Summary

Clackamas County can order a substandard or dangerous building repaired, vacated or demolished as a public nuisance under Chapter 9.01 of the county code. The Building Official issues a formal notice and order once an inspection finds any of thirteen listed dangerous conditions, from structural failure to a building with no potable water.

These county ordinances apply to unincorporated areas of Clackamas County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

All buildings or portions thereof, which are determined after inspection or receipt of other verifiable information to be dangerous, as defined in this chapter, are hereby declared to be public nuisances and shall be abated by repair, rehabilitation, demolition, or removal in accordance with the procedure specified in Section 9.01.100 of this chapter. In addition to abatement as described herein, a dangerous building may be ordered to be vacated subject to the provisions of this chapter.

Full Breakdown

100 lists the qualifying conditions: structural instability that could cause collapse, blocked exits, occupancy that creates a fire or health hazard, inadequate plumbing, light or ventilation, fire hazards under the Oregon Fire Code, unsafe building systems, hazardous accumulated waste, environmental hazards, and an occupied building lacking potable water or a functioning sewer or septic connection. 110 requires a written notice and order to the record owner describing the specific defects, the required action (repair, vacate or demolish), and a deadline, capped at 60 days to commence permitted repair or demolition work.

The order must also state the owner's right to appeal to the Code Compliance Hearings Officer within 30 days of service, and that failure to appeal waives the right to a hearing. 120 documenting the finding. 030 authorizes the Building Official, the Deputy Building Codes Administrator, the Plan Review Supervisor and the Structural/Mechanical Inspector Supervisor to act as authorized representatives in these proceedings.

Violations & Fines

Section 9.01.070 makes it unlawful to construct, alter, repair, occupy or maintain any building in violation of the dangerous-buildings chapter or the Building Code. If an owner does not comply with a repair, vacate or demolition order and does not appeal within 30 days, the county can proceed to do the work itself under the chapter's remedies and recover the cost against the property or the owner under Section 9.01.250, in addition to any injunction, abatement or other court action the county pursues.

Frequently Asked Questions

What makes a building 'dangerous' under Clackamas County code?
Section 9.01.100 lists thirteen qualifying conditions, including structural instability that risks collapse, blocked exits, occupancy that creates a fire or health hazard, inadequate plumbing or ventilation, unsafe electrical or mechanical systems, hazardous waste accumulation, and an occupied building without potable water or a working sewer or septic connection. Any one condition that endangers life, health, property or safety is enough.
What can the county require the owner to do?
Under Section 9.01.110, the Building Official's notice and order can require repair, vacating, or demolition, with permitted work required to start within 60 days of the order for repair or demolition cases. The order must describe the specific dangerous conditions found and the owner's 30-day right to appeal to the Code Compliance Hearings Officer.
Can the county demolish a building itself?
Yes. Section 9.01.060 authorizes abatement 'by repair, rehabilitation, demolition, or removal,' and if the owner misses the deadline in the notice and order without appealing, the county can perform the work and recover its cost from the property or owner under the chapter's cost-recovery provisions.
How does an owner appeal a dangerous-building order?
Section 9.01.110(A)(5) requires the notice and order to state that any person with a recorded interest in the building may appeal to the Code Compliance Hearings Officer in writing within 30 days of service. Missing that deadline waives the right to a hearing, under Section 9.01.160.
