If you build in Colorado, the rules that govern your business sit in three places: the state licensing authority, the state lien statute, and the state prevailing-wage law. Cost bands, permit timelines, and common project types layer on top. Get any of these wrong and you bid the wrong number, miss the lien deadline, or lose the certificate of occupancy. Here’s what Coloradocontractors need to know in 2026, plus how BuildCrux fits into your daily workflow.
BuildCrux runs AI estimating, scheduling, change-order management, lien-aware invoicing, mileage tracking, and customer communication in one place. Every screen is built for the field, not the back office. The numbers below come from current state law, published cost references, and 2026 market data. Verify specific project rules with your AHJ before bidding.
Colorado contractor licensing
Colorado Department of Regulatory Agencies (DORA) for specialty trades; city/county for GCs
No state-level general contractor license. Cities and counties (Denver, Colorado Springs, etc.) require their own GC license. Electrical and plumbing are state-licensed through DORA.
- Application + first-year fees
- State electrical/plumbing: $50-$200 application + bond. City GC license fees vary widely.
- Renewal period
- 2-3 years (state) / varies (city)
Mechanics liens in Colorado
Filing deadline: 4 months after last work for original contractors; 2 months for materialmen and laborers. Lien is filed with the clerk and recorder of the county where the property is located.
Preliminary notice: Colorado requires a Notice of Intent to File Lien served on the owner at least 10 days before filing the mechanics lien itself. Direct contractors are not exempt from this requirement.
Lien rights are how you actually get paid when an owner stops paying. Missing the deadline forfeits the security entirely. The mechanics lien is the contractor’s primary security; the preliminary notice is the prerequisite that protects it. Read the lien waiver entry too — that’s the document you’ll exchange for every progress payment.
BuildCrux tracks your last-work date per project and surfaces lien-deadline reminders so the math doesn’t happen on the back of an envelope at month-end.
Prevailing wage in Colorado
Colorado expanded its prevailing-wage law in 2019 to cover state-funded projects $500,000 and above. The Colorado Department of Labor and Employment publishes wage rates by trade.
For background on how prevailing-wage rules work, see our prevailing wage glossary entry and the Davis-Bacon Act explainer. The federal U.S. Department of Labor wage determinations site publishes prevailing rates on federally funded projects.
