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.

Common Mistakes to Avoid
- 1

Subcontractors without proof of insurance
- 4
Poor project scheduling causing costly delays
- 5
No written contracts with payment schedules
Next Steps to Launch Your General Contracting Business
- 1
Form your LLC or corporation in Colorado — general contractors carry significant liability for subcontractor work and project defects (filing fee: $50)
- 2
Obtain your Colorado general contractor license — requires experience documentation, exam, and financial statements in most states
- 3
Obtain a contractor surety bond and general liability insurance — bond requirements vary by state and the GL premium is typically a meaningful four-figure annual cost; both are required for most permits and contracts
- 4
Complete OSHA 30-Hour Construction Safety training — required by most commercial project owners and insurance carriers
- 5
Register with Colorado Contractor State License Board or equivalent regulatory agency and maintain license with required continuing education
- 6
Build a subcontractor network: licensed plumbers, electricians, HVAC techs, and framers — GCs depend on reliable subs for project quality
- 7
Create a construction contract template using AIA or AGC contract forms covering scope, payment schedule, change orders, and warranty
- 8
Get workers' compensation insurance before hiring any employees or subcontractors — Colorado requires WC for all construction workers
