Colorado does not issue a single statewide “general contractor” license for typical handyman/general construction work; licensing is primarily handled by cities/counties through contractor registration plus building permits. However, Colorado DOES require state-issued licenses for certain trades (notably electrical and plumbing), and those trade licenses apply statewide. In Johnstown (Weld/Larimer area), you should expect to (1) register as a contractor with the local building department(s) where you pull permits and (2) hold any required state trade license for regulated work; a broad statewide “handyman exemption” dollar threshold is not how Colorado is structured.
