What a construction lender needs to know about Colorado

Colorado splits the collateral: record before work starts and the deed of trust holds the land, but a mechanics lien takes super-priority over a newly built structure regardless of recording date, and all liens relate back to the first visible work. Retainage is capped at 5% on commercial and multi-family (5+ units) projects over $150,000, with 1–4 units contract-governed. Colorado has no statewide GC license — unlicensed contractors keep full lien rights — and every lien waiver must contain a specific statutory sentence to be valid.

Paying in full is a defense, but only on a home.

Colorado’s statutes give contractors extraordinarily strong protections, and liens attach as of the first visible work. The owner’s protection is narrow: pay the principal contractor in full on an existing single-family home, or a new one intended as the owner’s primary residence, and that is an absolute defense to sub-tier liens.

On commercial and multi-family, full payment is no defense — the exposure is paying twice.

Existing single-family, or new primary residence
Full payment to the contractor defeats sub-tier liens.
Commercial and multi-family
Full-price liability if the contractor fails to pay downstream.

Super-priority on the new improvement.

This is the rule that surprises out-of-state lenders. On a newly constructed structure, a mechanics lien takes priority on the improvement itself even over a deed of trust recorded first. Your prior recording holds the raw land, and only the land.

Remodels behave normally — a prior-recorded deed of trust keeps the land and the existing structure. And if any visible work precedes your recording, liens take both.

An unlicensed contractor still gets a lien.

There is no statewide general contractor license — contracting is licensed city by city — and unlicensed contractors keep full mechanics lien rights. The lack-of-license defense that works in many states does not exist here.

Verify locally, not statewide
Registration and permits come from the municipality: Denver, Colorado Springs, Boulder, and so on.
Trades are state-licensed
Electricians and plumbers are licensed through DORA and can be verified centrally.
No statewide bond
Private general contractors carry no state surety requirement; local compliance bonds are common.

No prescribed form, but one sentence is mandatory.

Colorado publishes no waiver form, yet a waiver is invalid without a statement that debts owed to third parties for the covered goods or services have been paid or will be paid on time. Get that sentence into your form.

Unusually, advance waivers are legal here — but courts read them very strictly and they bind only the contracting parties, so do not build your file on one.

A 10% holdback can be illegal here.

On private contracts over $150,000 for commercial or multi-family work, retainage is capped at 5%. A standard 10% retainage clause in the construction contract violates the statute. Contracts for a single-family home, or four units or fewer, are exempt and run on contract terms.

There is no private prompt payment act, so payment timing is whatever the prime contract says.

Colorado Lien Law Overview

Colorado’s mechanics lien laws provide extraordinarily powerful protections for contractors, subcontractors, materialmen, and laborers. The statutes operate under a strict “relation-back” doctrine, meaning liens generally attach as of the date the very first visible work began on the project.

A critical statutory distinction exists between residential and commercial properties regarding an owner’s liability. On existing single-family dwellings, as well as new construction of a single-family home intended to be the owner’s primary residence, if the owner pays the principal contractor in full, it serves as an absolute affirmative defense against any sub-tier mechanics liens (C.R.S. § 38-22-102(3.5)). Conversely, on commercial and multi-family projects, the owner and lender are exposed to full-price lien liability (paying twice for the same work) if the general contractor fails to pay downstream subcontractors.

At-A-Glance Critical Deadlines:

  • Notice of Intent to File Lien: 10 days prior to filing the actual lien statement (C.R.S. § 38-22-109(3)).
  • General Lien Filing Deadline: 4 months from the claimant’s last furnishing of labor or materials (C.R.S. § 38-22-109(5)).
  • Laborer Lien Filing Deadline: 2 months from the completion of the building or improvement (C.R.S. § 38-22-109(4)).
  • Lien Foreclosure Deadline: The absolute deadline to commence a lien foreclosure action and record a lis pendens is strictly six (6) months after the last work or materials are furnished, or the date of project completion (C.R.S. § 38-22-110).
  • Notice of Extension: The 1-year timeframe under C.R.S. § 38-22-109(8) pertains only to filing a Notice of Extension of Time to File a Lien Statement, not the expiration of the perfected lien itself.

Mortgage Priority

Colorado presents an extreme priority risk to construction lenders. The state utilizes a “bifurcated” priority system and a strict “relation-back” doctrine that inherently favors contractors over lenders.

Super-Priority on New Improvements: Unlike most states, recording a construction deed of trust prior to the commencement of work does not guarantee absolute first-lien priority on the entire asset. Under C.R.S. § 38-22-103(2), if a mechanic’s lien is filed for work on a newly constructed “entire structure,” that mechanic’s lien takes super-priority on the improvement itself, even over a prior recorded construction deed of trust. The lender’s prior-recorded mortgage only retains its first-position priority on the raw land. This means lenders cannot rely solely on recording their mortgage first to protect a newly built asset. (Note: This super-priority applies specifically to new construction. For remodels/renovations of existing structures, a prior-recorded deed of trust maintains priority on both the land and the existing structure).

Relation-Back to Commencement: Furthermore, under C.R.S. § 38-22-106(1), all mechanics liens relate back in time and take priority as of the date of the very first physical work or delivery of materials to the site. If any visible work commences before the lender’s deed of trust is recorded, the mechanics liens relate back and leapfrog the lender, taking absolute first-lien priority on BOTH the improvements and the land.

Because the lender’s collateral interest in newly constructed buildings is inherently subordinate to mechanics liens by statute, lenders must rely heavily on draw-by-draw title endorsements and strict lien waiver collection to protect their investment.

Retainage Overview

Colorado heavily regulates private retainage, acting as a major compliance trap for out-of-state lenders unaware of recent statutory limits.

Multi-Family (5+ Units) & Commercial: For private construction contracts exceeding $150,000, retainage withholding is strictly capped. An owner, contractor, or subcontractor must not withhold more than 5% of the price of the completed work as retainage pursuant to C.R.S. § 38-46-102. Any contract provision attempting to withhold a standard 10% on these projects violates state law.

Residential (1-4 Unit): Private contracts governing the building of a single-family dwelling, or a multi-family dwelling with four or fewer units, are explicitly exempt from the 5% statutory cap (C.R.S. § 38-46-102(3)). For these properties, the retainage percentage (e.g., 10%) is governed entirely by the terms of the private construction contract.

Escrow: Colorado does not statutorily mandate that private retainage be held in a separate, interest-bearing escrow account.

Prompt Payment Act

Colorado does not have a comprehensive Prompt Payment Act applicable to private construction projects.

Residential (1-4 unit), Multi-Family, & Commercial: Payment deadlines, frequency, and penalties for late payments on private projects are dictated entirely by the terms of the private construction contract. Draw administrators handling private loans should rely strictly on the specific payment timelines negotiated in the borrower’s prime contract to avoid breach of contract claims. (Note: Colorado enforces strict prompt payment laws for public works projects under C.R.S. § 24-91-103, but these do not apply to private lending).

Title Practices

Under Colorado law, state statutes do not require title companies to administer construction loan disbursements. Lender-managed disbursements (or third-party draw administration) represent the standard industry practice.

To maintain first lien priority, verifying title and monitoring for liens at each draw is the primary best practice. Construction lenders have three primary options to achieve this: (1) Lien monitoring subscription services, (2) Title updates (which check public records but do not provide insurance), and (3) Title endorsements (which provide actual insurance to the lender).

Because Colorado law dictates that mechanics liens hold super-priority on new improvements and relate back to the very first visible commencement of work, “hidden” and “gap” liens pose an extreme threat. It is highly recommended that construction lenders utilize ALTA 32 (Construction Loan) and ALTA 33 (Disbursement) title endorsements (or their equivalents). Obtaining these endorsements shifts the severe risk of statutory super-priority, unrecorded “gap” liens, and disputes over physical commencement dates from the lender to the title insurer. Regardless of the method chosen, leveraging these tools to clear encumbrances and verify public filings prior to releasing every single draw is crucial to mitigating risk.

Lien Waivers

Colorado does not mandate or publish specific, fill-in-the-blank statutory forms for lien waivers. However, under C.R.S. § 38-22-119(2), the state dictates a mandatory sentence that must be included within any lien waiver to render it valid.

An agreement to waive lien rights must contain a statement, by the person waiving the lien rights, providing in substance that: “All debts owed to any third party by the person waiving the lien rights and relating to the goods or services covered by the waiver of lien rights have been paid or will be timely paid” (C.R.S. § 38-22-119(2)).

Lien Waiver Summary

Colorado’s treatment of lien waivers is unique because it permits advance waivers, often referred to as “no-lien clauses.”

Advance Waivers: Under C.R.S. § 38-22-119(1), parties can legally agree to waive, abandon, or refrain from enforcing a mechanics lien before work begins or payment is made. However, courts construe these advance waivers extremely strictly, and they are only binding between the parties to the specific contract.

Best Practice: While advance waivers are legally permissible, relying on them creates significant friction with contractors. It is highly recommended that lenders enforce a draw-by-draw exchange using custom, legally vetted forms containing the mandatory third-party debt language. Lenders should exclusively collect Conditional Waivers for the current draw request (expressly conditioned on the clearance of funds) and Unconditional Waivers for previously funded draws.

Lien Waiver Notarization

Colorado law does not require lien waivers to be notarized to be considered legally valid and effective. A signed, written agreement containing the mandatory statutory text is sufficient.

Notices

Notice of Commencement (or similar like event)

Colorado DOES NOT utilize or recognize a standard “Notice of Commencement” to establish project start dates. Priority is strictly determined by the physical, visible commencement of work on the site. However, Colorado utilizes a unique “Notice of Disburser” mechanism to publicly identify the lender.

Preliminary Lien Notifications

Colorado requires specific preliminary notices depending on the claimant’s role and their intent to trap funds or file a lien:

  • Notice of Intent to File a Lien Statement: All claimants (general contractors, subcontractors, suppliers) must serve a Notice of Intent upon the owner or reputed owner at least 10 days before officially recording a mechanics lien statement with the county clerk. Under C.R.S. § 38-22-109(3), this 10-day notice must be served via personal service or by registered or certified mail, return receipt requested.
  • General Funds Trapping Notice: Under C.R.S. § 38-22-102(2), any person performing labor or furnishing materials may give written notice to the owner, reputed owner, or superintendent of construction that they have performed work or furnished materials. Upon receiving this notice, the owner must withhold from the principal contractor sufficient money to satisfy the claim. Furthermore, under C.R.S. § 38-22-126(3), upon written request, the owner has a statutory duty to furnish the names and addresses of the lender and contractor to any claimant.
  • Notice to Disburser (Lender-Specific Funds Trapping): Any claimant may send a preliminary notice directly to the construction lender (the disburser). Once received, it is the duty of the disburser to ascertain the amount due to the claimant and pay them directly out of any undisbursed funds pursuant to C.R.S. § 38-22-126(6).

Notice of Completion (or similar like event)

Colorado DOES NOT utilize a statutory Notice of Completion to truncate or alter the deadline for contractors to file mechanics liens. Claimants generally have 4 months (or 2 months for day laborers) from their last date of furnishing to file a lien (C.R.S. § 38-22-109(5)).

However, lenders managing stalled or defaulted loans should monitor for project abandonment. Under C.R.S. § 38-22-109(7), the discontinuance of all labor, work, and materials for a three-month period is legally deemed equivalent to project “completion.” This three-month abandonment triggers the start of the 4-month countdown for claimants to record their final mechanics liens.

Additional State-Specific Notices

Notice of Disburser: Under C.R.S. § 38-22-126(1), recording a Notice of Disburser in the county clerk’s office is an optional right, not a mandatory statutory duty. However, it is a highly recommended protective mechanism for the construction lender prior to the first disbursement. This notice publicly states the name and address of the owner, principal contractor, and the disburser. It directs potential lien claimants on exactly where to send their “Notice to Disburser” to trap funds. Failing to record it does not violate state law, but it removes a critical layer of defense. Criticality of Routing Address: It is vital that the lender’s address listed on this recorded notice is the exact, specific routing address (e.g., a specific department or draw administrator’s attention) rather than a generic corporate headquarters or branch address. If a subcontractor mails a trapping notice to a generic address and it gets lost internally, the lender remains strictly liable for the trapped funds if they subsequently disburse money to the General Contractor.

Notice to Disburser (Funds Trapping): As established under C.R.S. § 38-22-126(6), if a lender receives this notice from an unpaid subcontractor or supplier, the lender must ascertain the amount due and pay the claimant directly out of the undisbursed loan funds. If the lender ignores this notice and pays the general contractor instead, the lender is directly, personally liable to the claimant for the amount they should have paid to the extent of the claimant’s loss (C.R.S. § 38-22-126(7)).

Recording the Construction Contract: Under C.R.S. § 38-22-101(3), if the prime construction contract exceeds $500, the contract (or a memorandum of it) should be recorded in the county clerk’s office before work begins. Benefit: By recording the contract, the owner and construction lender establish a strict financial ceiling on their lien liability, capping the total amount of mechanics liens that can be filed by sub-tiers at the original contract price.

Example and Implications: For instance, if the original recorded prime contract is $500,000, but the GC mismanages funds and racks up $700,000 in unpaid subcontractor invoices, the maximum lien exposure against the property remains capped at $500,000. If the contract is NOT recorded, subcontractors and materialmen are legally deemed to have contracted directly with the owner. In that scenario, the property and the lender’s collateral would be fully exposed to the uncapped $700,000 in mechanics liens, potentially wiping out the project’s equity.

Construction Trust Fund Statute: Under C.R.S. § 38-22-127, all funds disbursed to a contractor are statutorily held “in trust” for the payment of subcontractors and suppliers. If a General Contractor accepts a draw from the lender but fails to properly disburse the funds downstream, the GC commits civil theft. This carries massive liability, subjecting the contractor to treble damages (three times the amount stolen) and attorney’s fees under C.R.S. § 18-4-405, as well as potential felony criminal charges. Lenders can use the threat of this statute as extreme leverage when mediating disputes between a GC and an unpaid subcontractor.

Affirmative Defense (Owner Protection): For existing single-family dwellings, as well as new construction of a single-family home intended to be the owner’s primary residence, if the owner (or lender on their behalf) makes payments to the general contractor in an amount sufficient to satisfy the contractual obligations, it constitutes an absolute affirmative defense against any sub-tier liens (C.R.S. § 38-22-102(3.5)).

Document References

Notice of Disburser:

An optional statutory document that can be recorded by the lender prior to the first draw. It benefits the lender by centralizing where claimants must send notices to trap funds, providing a structured early warning system. While failing to record it does not violate state law, doing so is highly recommended to protect the lender. If utilized, C.R.S. § 38-22-126(2) requires this document to contain the following specific data fields: the name and address of the owner; the names, addresses, and telephone numbers of the principal contractor and disburser (lender); and the legal description and physical address of the land.

Notice to Disburser:

A statutory notice served by an unpaid claimant directly on the construction lender. It benefits the lower-tier claimant by trapping unexpended loan funds. If the lender fails to freeze and redirect the funds to the claimant, the lender becomes personally liable for the financial loss under C.R.S. § 38-22-126(7).

Notice of Intent to File a Lien Statement:

A mandatory statutory warning notice served on the property owner. It must be served at least 10 days before a formal mechanics lien is recorded, via personal service or registered/certified mail with return receipt requested, as mandated by C.R.S. § 38-22-109(3). It provides the lender and owner a final 10-day window to trap funds and resolve the dispute before title is encumbered.

Statement of Lien (Mechanics Lien):

The formal, notarized document recorded in the county clerk’s office to perfect the lien against the property. It must be filed within four (4) months (or two months for pure laborers) after the claimant’s last date of furnishing labor or materials in accordance with C.R.S. § 38-22-109(5).

Contractor Licensing & Bond Requirements

Colorado does not issue a centralized, statewide “General Contractor” license. Instead, general contracting is regulated entirely at the local (city or county) level.

  • Lien Rights (Critical Distinction): Unlike many states, an unlicensed contractor who supplies labor or materials in Colorado maintains full mechanics lien rights (C.R.S. § 38-22-101). Lenders cannot rely on a lack of licensure to defeat a mechanics lien claim.
  • Local Licensing: Contractors should ensure they are registered and pull permits directly with local municipalities (e.g., Denver, Colorado Springs, Boulder) as dictated by local municipal codes. These jurisdictions define their own insurance, exam, and compliance bond requirements.
  • Specialty Trades: Electricians and plumbers are strictly regulated and must be licensed at the state level by the Colorado Department of Regulatory Agencies (DORA) pursuant to C.R.S. Title 12, Article 115 (Electricians) and C.R.S. Title 12, Article 155 (Plumbers).
  • Surety Bonds: There is no statewide surety bond requirement for private general contractors, though local municipalities frequently require a local compliance bond to operate.
  • License Lookup: Lenders should verify specialty trades via the DORA Online Services Portal, and verify general contractors directly with the local municipal building department.

Frequently Asked Questions

A framing subcontractor sent us a “Notice to Disburser” claiming they are owed $25,000. The General Contractor disputes the quality of the framing and demands we release the full draw to them. What must the draw administrator do?

Under C.R.S. § 38-22-126(6), when a lender receives a Notice to Disburser, the lender is legally required to ascertain the amount due and pay the claimant directly out of undisbursed funds. The lender cannot act as the judge of the quality dispute and simply ignore the notice to satisfy the GC. If the draw administrator releases the full draw to the GC and ignores the notice, the lender becomes personally, directly liable to the framing subcontractor for the $25,000 loss pursuant to C.R.S. § 38-22-126(7). You should immediately freeze the disputed $25,000 and either issue a joint check once the parties reach an agreement or hold the funds until the dispute is legally resolved.

We are financing a $5 million commercial ground-up build. The private contract requires the owner to hold 10% retainage until final completion. Is this enforceable in Colorado?

No, this is a direct violation of state law. Under House Bill 21-1167 (codified at C.R.S. § 38-46-102), for private construction contracts exceeding $150,000, retainage withholding is strictly capped at a maximum of 5% of the price of the completed work. Because this is a commercial project (not an exempt 1-4 unit residential dwelling), attempting to withhold 10% is legally void and exposes the borrower to breach of contract claims. The draw administrator should immediately adjust the loan holdbacks to comply with the 5% cap.

We noticed the General Contractor crossed out the sentence “All debts owed to any third party… have been paid or will be timely paid” on the lien waiver before signing it. Can we accept the waiver?

Absolutely not. Under C.R.S. § 38-22-119(2), this exact statement is a mandatory statutory requirement for an agreement to waive lien rights to be valid. By crossing it out, the contractor has rendered the document legally defective. If you accept the altered waiver and disburse funds, you are doing so without a valid release of lien rights, meaning the contractor could legally file a mechanics lien later. You should reject the waiver and refuse to release the draw until a clean waiver containing the mandatory statutory text is signed.

A HUD consultant is insisting we accept a generic lien waiver form generated by their proprietary software for a progress draw, but we noticed the form is missing the mandatory “third-party debt” language. Should we accept it to avoid delaying the draw?

No, you should not accept it. Regardless of whether the form is generated by a HUD consultant, proprietary software, or any other third-party system, it must comply with Colorado law to effectively waive lien rights. Because C.R.S. § 38-22-119(2) strictly dictates that the “third-party debt” statement is a statutory requirement for validity, accepting a generic form without this language means the lender is disbursing funds without securing a legally binding waiver. The draw administrator should reject the generic form, explain the statutory requirement, and provide the consultant or contractor with a custom, legally vetted waiver form that includes the necessary language.

Our pre-closing site inspection revealed that the borrower authorized the GC to clear brush and dig a small trench on the site yesterday. We are scheduled to record our construction deed of trust tomorrow. How does this impact our priority?

Because Colorado operates on a bifurcated system with a strict “relation-back” doctrine (C.R.S. § 38-22-106(1)), the physical clearing of brush constitutes the visible commencement of work. Any mechanics liens filed on this project will relate back to yesterday’s date. Since you are recording your deed of trust tomorrow, your mortgage will be entirely subordinated to all subsequent mechanics liens on BOTH the raw land and the physical improvements. You should immediately halt the closing process and request that the title insurer provide specific affirmative coverage (such as an ALTA 32 endorsement) to insure over this pre-existing commencement risk before advancing any funds.
