In Colorado’s construction industry, missing a lien deadline does not just cause delays — it eliminates your right to payment entirely. The Colorado mechanics lien timeline is governed by strict statutes with no room for error. Contractors, subcontractors, and suppliers all face different windows depending on what they provided on a project. Baker Law Group, PLLC is here to guide construction professionals through this process and make sure every deadline is met. Knowing the Colorado mechanics lien deadlines before the clock runs out is the difference between getting paid and walking away with nothing.
How Long Do You Have to File a Mechanics Lien in Colorado?
This is the question most contractors and subcontractors ask first — and for good reason. In Colorado, how long you have to record a mechanics lien depends on what you provided to the project, and the clock is set by statute.
- Labor‑only (day or piece work, without furnishing materials or laborers): You must record your lien within two (2) months after the improvement is completed (i.e., completion of the building, structure, or other improvement). This deadline is tied to completion, not your personal last day on site.
- Materials, or a combination of labor and materials: You must record your lien within four (4) months after the day you last furnished labor or materials to the project.
These windows are measured from the statutory events above (last furnishing or completion) — not from when a payment dispute began. If you finished work weeks ago and still have not been paid, the clock may already be running.
Why the Colorado Mechanics Lien Timeline Matters
Mechanics liens are one of the most powerful tools available to those in the construction industry. They secure payment for labor, materials, or other services provided on a property. In Colorado, these liens are governed by strict statutes that outline who can file, what procedures must be followed, and — most importantly — when each step must happen.
The rules are firm. A lien filed one day late is an unenforceable lien. A notice sent to the wrong party does not count. Colorado courts apply these standards without exception, which is why understanding the full Colorado mechanics lien timeline from the start is essential.
The Colorado Mechanics Lien Deadlines: Step by Step
The Colorado mechanics lien deadlines involve three distinct steps. Each one must happen in the correct order and within the required timeframe. Missing any one of them can end your claim entirely.
Step 1: Send the Notice of Intent to Lien
Before filing anything with the county, you must first send a notice of intent to lien to the property owner. Colorado law requires this notice to be sent at least 10 days before the lien is filed. The notice of intent to lien informs the property owner of the unpaid balance and signals that a lien will be filed if payment does not follow. This step is not optional — it is a legal requirement under Colorado law.
The notice of intent to lien also serves a practical purpose. It gives the property owner a final opportunity to resolve the dispute before a lien is recorded against their property. In some cases, sending this notice alone prompts payment without any further legal action.
Step 2: File the Lien with the County Recorder
After sending the notice of intent to lien and allowing the required 10 days to pass, the actual lien must be filed with the county recorder’s office in the county where the property is located. This filing must happen before the two-month or four-month deadline expires. Filing in the correct county is just as important as filing on time.
Step 3: Enforce the Lien
Filing the lien is not the final step. Once filed, you have six months from either the last date labor or materials were provided — or six months from when the project was completed, whichever is later — to enforce the lien. Enforcement means initiating a foreclosure action in court. If this step is not taken within six months, the lien expires and is no longer enforceable.
This six-month enforcement window is one of the most overlooked parts of the Colorado mechanics lien timeline. Many contractors file correctly but then fail to take action within the enforcement period. At that point, the lien they worked to protect becomes worthless.
What Happens If You Miss a Deadline?
Missing any stage of the Colorado mechanics lien deadlines results in the forfeiture of lien rights. There is no grace period under Colorado law. A late filing, a missing notice, or a failure to enforce within six months all carry the same result — you lose your legal claim to payment.
This is why how long do you have to file a mechanics lien is one of the first questions to answer on any unpaid construction project. The longer the dispute sits unresolved, the shorter the remaining window becomes.
The Notice of Intent to Lien: What It Must Include
The notice of intent to lien must be properly prepared and delivered to the right party. Errors in this notice — wrong recipient, missing information, or late delivery — can invalidate the entire lien claim even if the rest of the process was followed correctly.
Colorado law requires the notice to inform the property owner of the unpaid balance and state the intent to file a lien if payment is not made. It must be served at least 10 days before the lien is filed. This is why many construction professionals work with an attorney to prepare and deliver this document rather than handling it alone.
Lien Waivers and Releases
During the payment process, parties sometimes request lien waivers or releases. These documents waive a party’s right to file a lien in exchange for payment. It is essential to understand the terms of any waiver before signing. You should confirm that payment has been received before submitting a waiver or release. Signing too early can eliminate your lien rights before payment clears.
