The document discusses the county health department's guidelines and procedures for investigating mold complaints. It provides information on different types of mold, health effects, exposure limits, prevention, removal procedures, and guidelines for landlords and tenants. The health department investigates indoor mold issues in rental properties and recommends removal of black mold over 10 square feet but does not regulate outdoor, attic, or basement mold unless it poses a health risk. Proper moisture control and cleaning are key to preventing mold growth.
