Your facility must comply with Portland zoning laws, fire codes, and building safety standards. This may involve permits through the City of Portland’s Bureau of Development Services, while construction/building codes are governed at the state level through the Oregon Department of Consumer & Business Services.

Step 5: Hire Licensed Staff & Prepare for Inspection

Oregon requires rehab centers to hire licensed counselors, medical staff, and behavioral health professionals as outlined in the OARs. You’ll also need written policies for:

Medication handling
Emergency preparedness
Recordkeeping & infection control

After submission, OHA conducts an on-site inspection before granting approval.
