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.

City-specific rules exist: Salem has its own smoke detectors rules that differ from Marion County's county-level regulations. If you live in Salem, check the city-specific page instead.

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. Battery-only ionization alarms sold in Oregon must come with a 10-year sealed battery and a hush feature. Alarms are required in each bedroom, outside sleeping areas, and on every level. These statewide standards apply throughout Marion County, including unincorporated areas.

Violations & Fines

Violations of the smoke-alarm statutes carry penalties under ORS 479.990. Landlords who fail to maintain alarms also face habitability claims from tenants.
