Health Department continues mandatory wood-burning restriction due to increased air pollution

August 7, 2026 - 21:04

Multnomah County officials have extended the mandatory wood-burning restriction, citing persistently high levels of air pollution across the region. The order, which first went into effect earlier this week, remains in place until further notice, and residents are being asked to avoid using fireplaces, wood stoves, and outdoor burn barrels.

The county's health department issued the advisory after air quality monitors recorded fine particulate matter concentrations that exceeded federal safety standards. These tiny particles, known as PM2.5, can penetrate deep into the lungs and have been linked to respiratory issues, heart problems, and worsened asthma symptoms. Children, older adults, and people with preexisting conditions are especially vulnerable.

Officials say the pollution is being driven by a combination of stagnant weather conditions, temperature inversions, and smoke drifting in from nearby agricultural burns. While some rain is forecast for the weekend, it is not expected to be enough to clear the air. Until then, the restriction applies to all households, including those with certified clean-burning stoves. The only exceptions are for homes where wood is the sole source of heat and no other option is available.

Residents are encouraged to use electric or gas heating instead, and to limit outdoor activity during peak pollution hours. The county will continue to monitor air quality and will lift the ban once readings return to safe levels. Anyone caught violating the order could face a fine, though officials say the goal is compliance, not punishment. People can check the county's air quality dashboard for real-time updates.
