Colorado licenses plumbers and electricians through state boards inside the Department of Regulatory Agencies (DORA), while many other trades are handled by cities and counties. These are the statewide rules we could confirm on official pages.

Colorado topics
Colorado HVAC
Colorado has no HVAC page of its own at DORA, so heating and cooling jobs touch several agencies: the Energy Office for heat pump credits, the state boards for gas and electrical work, and your city or county.
Colorado plumbing
Plumbing in Colorado is licensed statewide by the State Plumbing Board, and the state inspects plumbing in areas without a local program.
Colorado electrician
Electricians in Colorado are licensed by the State Electrical Board, which also inspects electrical work where no local authority does.
Colorado roofing
Colorado does not have a statewide roofer license page we could cite, but state law sets firm rules for residential roofing contracts, especially when insurance pays.
Colorado auto
Colorado car rules are spread across the Attorney General, the PUC, the Department of Revenue and the health department. These are the ones we confirmed.
Not covered yet
We have not published Colorado pages for these topics yet, because we have not confirmed enough Colorado specific facts on official pages: Appliance repair, Garage doors, Locksmith, Pest control, Movers.
