Auto Repair Shop Permit Requirements in Phoenix, AZ

1. EPA/RCRA Hazardous Waste Generator Requirements

   Auto repair shops that generate hazardous waste (spent solvents, contaminated absorbents, some paint wastes) must determine their generator category under RCRA rules, administered in Arizona by ADEQ. Very small quantity generators (100 kg/month or less) are exempt from the EPA ID requirement; small quantity generators (100-1,000 kg/month) must obtain an EPA ID number. Used oil and antifreeze are generally managed under separate recycling rules rather than as hazardous waste — check ADEQ guidance for your shop's specific waste streams.

1. Phoenix — No General Business License (regulated activities only)

   The City of Phoenix does not have or issue a general business license. The Phoenix City Clerk's License Services section licenses only specific regulated activities (amusements, auctions, curb painters, escort bureaus, massage establishments, sexually oriented businesses, and vending). Most businesses need no Phoenix city license at all; if you make taxable sales you must hold an Arizona Transaction Privilege Tax (TPT) license from the Arizona Department of Revenue ($12 state license per location plus a $50 Phoenix city license fee, both administered by AZDOR).
