Outside of the wood burning season, you can check current air quality in your area at DEQ’s air quality map or download OregonAir app on your phone. Check with your local fire departments for warm weather fire bans. 

Please choose to skip any unnecessary fires as smoke from fires can affect people in various ways and make symptoms and recovery from COVID-19 more difficult. Help spread the word, request a FREE lawn sign.  Thank you!

Burning wood is one of the biggest sources of harmful air pollution in Multnomah County. By not burning if you don’t need to, we can help keep the air healthy for children and people with asthma and other serious breathing conditions.

Wood Smoke FAQs (449.4 KB)

From October 1 through March 1, homeowners, renters and businesses in Multnomah County cannot use wood stoves, fireplaces or any outdoor wood burning devices on days when the air quality is forecasted to be poor. This includes:

  • Wood stoves

  • Fireplaces

  • Outdoor fire pits

  • Chimeneas

There are exceptions for those who use wood exclusively to heat their homes, those with limited income, and during emergencies such as a power outage. Households with an exception should apply for an exemption each year. There are no restrictions on wood or charcoal used for cooking.

Wood smoke restrictions are common in other communities around Oregon, and are designed to protect public health and keep our region in compliance with national air quality standards. 

If You Burn Wood in Fall and Winter

Check air quality conditions and burn status every time before you burn. Red means “stop.” Yellow means "limit". Green means “ok”.

If poor air quality is expected, Multnomah County will issue a burn restriction (red) day, which will take effect by noon the same day. Watch for messages on this page, social media channels (Twitter, Facebook, Nextdoor) and local news media.

You Can Still Use Your Grill

The ordinance does not apply to charcoal grills, smokers or wood fired ovens, so long as you’re only using them to cook food.

Backyard burning is NEVER permitted inside the DEQ Burn Ban Boundary. The Burn Ban Boundary includes parts of Multnomah, Clackamas, and Washington County. The Department of Environmental Quality (DEQ) regulates outdoor/backyard burning. For the areas outside of the Burn Boundary, cities and local fire districts have their own restrictions on open burning. For information on Outdoor Burn Status outside of the Burn Ban area in Mult Co.:
