Due to the fact that asbestos has been used extensively in residential, commercial and industrial construction, District Regulation 11-2-401.3 requires that for every renovation involving the removal of 100 sq ft/lin ft or greater of Regulated Asbestos Containing Material, and for every demolition (even when no asbestos is present), a notification must be made to the BAAQMD at least 10 working days (except in special circumstances) prior to commencement of demolition/renovation.
