Air Quality Permit Checklist

For city and county staff, California state law requires that business owners need to comply with the applicable permitting/registration requirements of the South Coast AQMD prior to the granting of an occupancy permit. This Air Quality Permit checklist will help to determine what is necessary to obtain clearance from South Coast AQMD.


South Coast AQMD hosts various small business events throughout the year which provide a bridge for communication between business owners, South Coast AQMD staff, and South Coast AQMD Board members. Please join us at these events, which are usually free of charge, and give us your feedback.
