Klickitat County does not have a local indoor or outdoor air quality code. Air quality code and enforcement is usually deferred to 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 Washington State Department of Ecology.
Mold growth in buildings is a results 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 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, you are covered under the Residential Landlord-Tenant Act in Washington State.
