EPA Section 608 certification is required for any technician handling refrigerant.

The city requires a license only for specific categories: alcohol sales, body art/tattoo facilities and artists, food establishments (bakeries, grocery/retail meat, restaurants, mobile food vendors, concession stands), childcare facilities, hotels/motels, taxi/towing operators, retail tobacco dealers, and a few other regulated categories. Building-trade licenses (electrician, plumber, mechanical installer, etc.) are issued separately by the Building Inspections Department. Check the city's license list for your specific business type before assuming a license is required.
