How do I file a mechanic's lien in Colorado?

Federal & State Law Editorial TeamLast reviewed: 2026-05-18

Colorado mechanic's liens are governed by Colo. Rev. Stat. §§ 38-22-101 through 38-22-133.

1. Who Can File

Contractors, subcontractors, sub-subs, material suppliers, architects, engineers, surveyors, and laborers performing labor or furnishing materials for improvements (Colo. Rev. Stat. § 38-22-101).

2. Preliminary / Pre-Lien Notice

At least 10 days before recording the lien statement, the claimant must serve a Notice of Intent to File Lien on the owner and principal contractor, by personal service or certified mail (Colo. Rev. Stat. § 38-22-109(3)). The lien may not be recorded earlier than 10 days after service.

3. Recording the Lien

Record a verified Lien Statement with the county clerk and recorder where the property is located. Principal contractors and laborers: within 4 months after the last day of work; persons furnishing only materials: within 2 months after last delivery (Colo. Rev. Stat. § 38-22-109(5)). The statement must include claimant, owner, work, amount, dates, and property description.

4. Service on Owner

The Notice of Intent satisfies pre-recording service; a copy of the recorded Lien Statement should also be provided. For foreclosure, all interested parties must be served.

5. Suit to Foreclose

File foreclosure within 6 months after the last work or after the completion of the structure (Colo. Rev. Stat. § 38-22-110). The lien may be extended for an additional 6 months (up to 1 year total) by recording an Extension Notice.

6. Priority

The lien attaches as of the date of commencement of work on the structure, taking priority over subsequent encumbrances; prior recorded interests are senior (Colo. Rev. Stat. § 38-22-106).

7. Bond Release

Owner may release the lien by recording a surety bond for 150% of the lien (Colo. Rev. Stat. § 38-22-131).

8. Homestead / Residential

For residential properties of 4 units or fewer, the principal contractor must hold all funds received from the owner in trust for subs and suppliers (Colo. Rev. Stat. § 38-22-127). Owner who has paid contractor in full has equitable defenses; § 38-22-102 limits lien against bona fide purchasers of single-family residences who paid in full before recordation.

9. Fraudulent Lien Penalties

Excessive amount: § 38-22-128 makes it a misdemeanor to record an excessive lien; the lien is forfeited and the claimant may be liable for actual damages.
