All contractor's obtaining building permits will need to be registered with Grand County. Sub-contractors will not need to be registered with Grand County, unless they are obtaining a building permit for their sub-trade work, not under a general contractor. (i.e. A plumber will need to be registered with Grand County to obtain a permit for a furnace installation, but do not need to be registered if they are a sub-contractor under a general contractor. The general contractor will obtain the building permit, and be required to register with Grand County.) Below are the applicable forms for contractor registration, along with the Contractor Registration Amendment.
