Summary
Oregon law, not a Marion County ordinance, sets smoke-alarm rules. Landlords must supply, install, and maintain working smoke alarms, and homes cannot be sold or rented without approved alarms in place.
The owner of any rental dwelling unit or the owner's authorized agent shall be responsible for supplying, installing and maintaining the required smoke alarms or smoke detectors.
Full Breakdown
Under ORS 479.270 the owner of any rental dwelling is responsible for supplying, installing, and maintaining the required smoke alarms and for giving tenants written testing instructions. ORS 479.260 bars conveying or transferring a dwelling, lodging house, or manufactured home without the required approved alarms installed.

These statewide standards apply throughout Marion County, including unincorporated areas.
