Air Quality

Klickitat County does not have a local indoor or outdoor air quality code. Air quality codes and enforcement are usually deferred to the Washington State Department of Ecology. Environmental Health staff does participate in emergency preparedness and during the summer we monitor air quality during wildfire season with the help of the Washington State Department of Ecology.

Mold & Renters

Mold growth in buildings is a result of water and moisture problems. Klickitat County Health Department does not have an indoor air quality program and does not enforce indoor air quality standards. Testing for mold is often arbitrary because in most cases you can see or smell mold. Clean-up should be done as soon as possible. If you are a renter, document the mold with pictures before clean-up. As a renter, you should operate heating and ventilation units to reduce water and moisture in the building. You also need to notify your landlord promptly, in writing, if there are any problems. If you rent, refer to the Residential Landlord-Tenant Act in Washington State for information.

If any issues persist, you may contact the State Attorney Generals Office Consumerline at   
1-800-692-5082, option 8.
