Rules by state
Oregon
Oregon has separate sale/transfer rules for smoke alarms and carbon monoxide alarms, with placement details set by the Office of State Fire Marshal. In the official Oregon sources reviewed, I did not find a statewide seller inspection sign-off or alarm certificate requirement before closing.
Checked against official sources on October 4, 2026. Rules and links change; confirm with the office listed before you act.
- At sale or transfer
- In Oregon, a seller generally must have required smoke alarms installed before transferring a dwelling, and must have properly functioning carbon monoxide alarms before sale when ORS 105.838 applies.

Key facts for Oregon
- ORS 479.260 bars conveying title or land-sale possession of a dwelling unless required smoke alarms are installed per code and State Fire Marshal rules.
- OSFM says sale-related smoke alarms belong inside each bedroom/sleeping area, outside bedrooms, and on every level, including basements.
- ORS 105.838 requires properly functioning CO alarms before sale if the home has a carbon monoxide source.
- OSFM says homes built during or after 2011 need a CO alarm regardless of a CO source; earlier homes need them when a CO source exists.
- OAR 837-047-0130 places CO alarms within each bedroom or within 15 feet outside each bedroom door on each level with bedrooms.
- ORS 479.297 requires solely battery-operated ionization smoke alarms sold in Oregon to be packaged with a 10-year battery and a hush feature.
What to do next
- Before listing, walk every bedroom level and verify smoke and CO alarm locations match OSFM guidance, then test each unit.
- If you want an independent check, hire an Oregon certified home inspector; state standards say inspectors observe smoke alarms and CO detectors.
- If you are replacing smoke alarms, choose models that satisfy Oregon’s 10-year-battery rule for solely battery-operated ionization alarms.
