General Business License
Colorado does not have a statewide general business license requirement. Businesses must register their entity with the Colorado Secretary of State and obtain a sales tax license from the Colorado Department of Revenue if selling taxable goods or services. Many municipalities require a local business license — Denver, Aurora, Colorado Springs, and Boulder all have their own business licensing programs with state-set annual fees that vary by program.

Home-Based Business Rules
Colorado municipalities regulate home-based businesses through local zoning ordinances. Denver allows home occupations with restrictions on customer visits (typically 1 person at a time), no exterior display, and no storage of commercial vehicles. Colorado State law preempts local regulations that would completely prohibit home-based businesses. The Colorado Cottage Food Act specifically authorizes home-based food production with certain limitations.

Next Steps to Launch Your Excavation Company
- 1
Form your LLC or corporation in Colorado — excavation companies carry enormous liability for underground utility strikes and earth movement (filing fee: $50)
- 2
Obtain your Colorado excavation or grading contractor license — most states require a specialty contractor license for earth-moving operations
- 3
Register with 811 (Call Before You Dig) and create a utility locate policy — calling 811 before every dig is legally required nationwide (https://call811.com/)
- 4
Obtain a contractor surety bond and general liability insurance — bond requirements vary by state and the GL premium is typically a meaningful four-to-low-five-figure annual cost; both are required by commercial clients and municipalities
- 5
Complete OSHA competent-person training for excavation and trenching (https://www.osha.gov/trenching-excavation) — required for all excavation operations over the OSHA depth threshold
- 6
Obtain heavy equipment operator certification for excavators, bulldozers, and graders used in your fleet
- 7
Register equipment with Colorado DMV for oversize/overweight permits if transporting equipment on public roads
- 8
Build relationships with general contractors, civil engineers, and utility companies — excavation subcontracts are the primary revenue source
