What Colorado Law Requires
Preliminary notice within 10 days
Colorado requires subcontractors and suppliers to serve a preliminary notice within 10 days of first furnishing labor or materials on private projects over $5,000. Miss the window and your lien rights — and your payment leverage — are gone.
No statutory waiver form, but waivers are standard
Colorado doesn't mandate specific statutory lien waiver language, but GCs routinely require conditional and unconditional waivers for every payment. Using a vague or unenforceable form puts your draws at risk.
COI requirements are contractual, not optional
Colorado doesn't set a statewide COI mandate, but every general contractor enforces insurance requirements contractually. A sub working on your job site without a valid certificate puts you on the hook for their liability.
W-9s before the first check
Federal law requires a W-9 from any sub you pay $600 or more in a year. Colorado construction moves fast — SubPaperz collects W-9s digitally so you're never scrambling at tax time.
We're not lawyers — this is general information, not legal advice. Talk to a Colorado construction attorney for guidance specific to your situation.
Every Colorado GC has been here. It doesn't have to keep happening.
In Colorado, the 10-day window is unforgiving. One missed notice from one sub can unravel your whole payment chain if the owner disputes a draw.
In Colorado, that liability lands on you. One incident without a valid COI can cost more than every job you've done this year.
Your subs are on job sites all day. Hunting down paperwork after hours shouldn't be part of your business model.
