Seattle's permit feed does not separately label pool contractors, solar contractors, remodeling contractors, fencing contractors, plumbing contractors, masonry contractors, landscaping contractors, roofing contractors, concrete contractors, drywall contractors, stucco contractors, window and door contractors, excavation contractors, insulation contractors, contractors that do both HVAC and plumbing, contractors that do HVAC, electrical, and plumbing together, contractors that do both solar and electrical, so we cannot rank those trades on local permit history here. Statewide license search still covers them.
