Licenses & Permits in Colorado

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 fees ranging from $25 to $500 annually.

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
Underestimating material costs and change order frequency
2
No lien waiver process protecting cash flow
3
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 ($10,000–$50,000) and general liability insurance ($2,500–$8,000/year) — 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

Frequently Asked Questions

Starting a general contracting business typically requires $20,000–$55,000, covering contractor licensing ($500–$2,000), surety bond, liability insurance ($1,500–$4,000/year), workers comp, a reliable work vehicle, tools, and working capital. Materials for active projects can require significant additional capital.

Most states require general contractors to be licensed. Requirements vary — some require passing a trade exam, others require proof of experience and financial responsibility. California, Florida, and Texas have strict requirements. Check your state contractor licensing board for specific requirements.

GCs earn 10–25% markup on subcontractor labor and materials. On a $200,000 remodel, a 15% GC margin generates $30,000 gross. After overhead, net margins average 8–15%. Larger commercial projects have lower margins but higher volume; custom residential work often commands 15–20%.

If subcontractors are true independent contractors with their own workers comp, the GC may be exempt. But if a subcontractor lacks coverage, the GC's policy may pay their claims. Always verify subcontractor insurance certificates — liability flows to the GC in most states.
