Caveats: Only the "Contractor and Construction Services" category (General Contractor/Construction Manager and Home Improvement Contractor business licenses). Most DC-licensed contractors are located in Maryland or Virginia; only those with a DC address appear in DC ZIP searches. No phone numbers. DC trade licenses (master plumber, electrician) are not in this open dataset. We show city, ZIP and phone (when the state lists one) but never street addresses.
