Deadlines, Substantial Completion, and the Rolling Lien in Massachusetts

Understanding when the lien clock starts — and exactly how much time you have at each stage — can be the difference between a fully enforceable lien and no lien at all.

In a previous article, I covered the fundamentals of Massachusetts mechanic’s lien law — who can file, what work qualifies, and what property can be reached. In this follow-up, I want to go deeper into the part of the statute that trips people up most often: the deadlines. Specifically, how “substantial completion” works as the trigger for lien filing windows, what happens when a project ends differently than planned, and the concept of the “rolling lien,” a mechanism that is genuinely clever but often misunderstood by contractors and lenders alike.

If you take nothing else from this article, take this: the lien clock in Massachusetts starts running from specific triggering events, not from when you decide to file. Miss the window and the lien is gone. There are no equitable exceptions, no extensions for honest mistakes, and no judicial relief for a claimant who simply waited too long.

Substantial Completion

The Massachusetts mechanic’s lien statute is built around the concept of “substantial completion.” Under G.L. c. 254, §§ 2, 2C, 2D, and 4, the date of substantial completion is the primary trigger for the period within which lien filings must be made. To understand how this works in practice, you need to understand two specific statutory notices: the notice of substantial completion under Section 2A, and the notice of termination under Section 2B.

What “Substantial Completion” Actually Means

Under Section 2A, substantial completion occurs when “work under the written contract is sufficiently complete so that it can be occupied or utilized for its intended use.” That is a practical, functional test. It does not mean every punch-list item is finished. It means the project has reached the point where it can serve the purpose for which it was built.

Substantial completion is not a formality — it is a legally significant milestone that starts the lien clock ticking for everyone on the project. When it is formally documented at the registry of deeds, all parties need to take immediate notice and act accordingly.

Filing a Notice of Substantial Completion

When the owner and contractor agree that substantial completion has been reached, they should file a “notice of substantial completion” at the registry of deeds. The statute provides a standardized form to ensure consistency. The owner must send notice by certified mail to any subcontractors who have already filed a notice of contract under Section 4. The general contractor must send certified mail notice to those with whom it has a written contract, and to anyone who has filed a notice of identification or notice of contract under Section 4.

Once the notice of substantial completion is recorded, the general contractor, all subcontractors and materialmen claiming through the general contractor, and any design professionals have sixty days within which to file their notices of contract, if they have not done so already. That window is not generous. Sixty days sounds like a reasonable amount of time until a project closes out and everyone moves on to the next job. If you are owed money and have not yet filed your notice of contract, the recording of a notice of substantial completion is the moment you need to act.

When the Project Ends Before Completion: The Notice of Termination

Not every project ends with a formal completion. Sometimes a dispute arises mid-project (a payment dispute, a performance issue, a fundamental disagreement between owner and contractor) and the owner terminates the general contractor before the work is done. The statute addresses this scenario directly through the notice of termination under Section 2B.

When an owner terminates the general contractor prior to substantial completion, the owner is entitled to record a notice of termination at the registry of deeds, again using a standardized statutory form. Notice is provided in the same manner as a notice of substantial completion, that is, certified mail to the appropriate parties.

Once the notice of termination is recorded, the general contractor and subcontractors (though notably, not design professionals in this scenario) have ninety days (rather than sixty days) to record their notices of contract. The extra thirty days reflects the more disruptive nature of a mid-project termination, where parties may not have been closely tracking filing deadlines.

The Default Rule: No Notice Filed

What happens if neither a notice of substantial completion nor a notice of termination is ever recorded? The statute provides a default position: all notices of contract must be recorded within ninety days after the last of labor and materials is furnished by the general contractor or anyone claiming through the general contractor.

This default rule is straightforward in concept but can create complications in practice, because the trigger is tied to actual work rather than to an administrative filing. Present case law holds that the time for filing a lien runs from the day work was completed for the proper performance of the contract, even if some of that work was performed after substantial completion. In other words, the clock runs from the last day of legitimate contract work, not from some theoretical completion date.

The Statement of Account — and When You Need One

Filing a notice of contract is not the end of the process. The statute also requires the recording of a statement of account, which sets out the amount claimed. The deadlines for filing a statement of account track the same triggering events as the notice of contract, but on a longer runway: ninety days after notice of substantial completion, or one hundred twenty days after notice of termination or after the contractor last furnished labor and materials. See G.L. c. 254, § 8.

There is one important exception worth knowing: if a target lien bond has been recorded pursuant to G.L. c. 254, § 14, a lien claimant is not required to record a statement of account in the registry of deeds. The existence of a target lien bond changes the procedural requirements, and a claimant operating in that context needs to understand what is and is not required.

One practical point the statute makes explicit: the trigger for these deadlines is the date of the actual event — substantial completion, termination, or last work — not the date the notice of contract is recorded. This matters because in many situations a notice of contract is not recorded until after the work is already done. When that happens, there is nothing in the statute preventing a claimant from recording the notice of contract and the statement of account simultaneously.

Enforcing the Lien: Filing Suit and Recording the Complaint

After the statement of account is filed, the contractor has up to ninety days to file a civil action to enforce the lien. See G.L. c. 254, §§ 5, 11. But filing the lawsuit is not enough on its own. The statute separately requires that an attested copy of the complaint be recorded in the registry of deeds within thirty days after the complaint is filed with the court. G.L. c. 254, § 5. If that recording step is missed, and no target lien bond is in place, the statute declares the lien invalid.

Massachusetts courts have held that a claimant had timely recorded its complaint because the complaint and the required fees were received by the registry within thirty days, even though the registry itself did not formally record the complaint until forty-four days after the action commenced. The receipt at the registry within the deadline was sufficient. That is a meaningful distinction, and it underscores the importance of getting to the registry promptly, not waiting until the deadline is imminent and then hoping the registry processes the filing in time.

Again, if a target lien bond has been recorded, the claimant is not required to record a copy of the complaint at the registry.

The Rolling Lien: How Contractors and Lenders Coexist

One of the more sophisticated concepts in the Massachusetts statute is what practitioners call the “rolling lien.” Understanding it requires understanding the tension the statute is trying to resolve: a general contractor files a notice of contract, which creates a lien with priority running from the date of that filing. A construction lender, meanwhile, is advancing funds on the project and wants its mortgage to have priority over the contractor’s lien. Those interests are in direct conflict — and the statute’s rolling lien mechanism is the compromise.

How the Rolling Lien Works

The statute creates a structured coexistence between the contractor’s lien and the lender’s mortgage through a partial waiver and subordination form. See G.L. c. 254, §§ 7, 32, 33. Here is how it works in practice:

When the general contractor provides the statutory partial waiver and subordination form, it waives its lien up to the amount it has already been paid. In exchange, the contractor preserves its lien priority with respect to retainage — the amount held back by the owner pending completion. The contractor also subordinates its lien for work performed in the twenty-five day period after the form is tendered, provided the contractor actually receives payment before that twenty-five day window closes.

The practical effect is that the bank maintains priority ahead of the contractor for new loan proceeds advanced after the contractor files its notice of contract — except for retainage. The contractor, in turn, gains priority in the retainage and can reassess its payment situation on a monthly basis as the cycle repeats. Once the general contractor provides the statutory partial waiver and subordination form, the statute goes further: it expressly prohibits lenders from refusing to advance funds solely because a general contractor has filed a notice of contract. That provision is designed to make the filing of a notice of contract a routine, non-hostile event in the course of every project.

The Rolling Lien in Summary

• Contractor files notice of contract — lien priority runs from that date
• Contractor tenders partial waiver & subordination form — waives lien for amounts already paid
• Contractor retains priority for retainage (amounts held back)
• Contractor subordinates lien for next 25 days of work — provided payment is received within that window
• Lender advances funds; cannot refuse solely because notice of contract is on record
• Cycle repeats monthly — contractor can reassess payment position each period

The Residential Exception: Projects with Four or Fewer Units

There is an important carve-out to the rolling lien provisions that every contractor working on smaller residential projects needs to know. For projects with at least one but not more than four dwelling units, the rules are different. Contractors with a direct contract on these projects do not get priority in the retainage, and lenders are not subject to the “forced funding” prohibition — meaning they can stop advancing funds upon learning that a Section 2 notice of contract has been recorded.

This residential exception reflects a policy judgment that the rolling lien mechanism — which was designed with larger commercial and multi-family projects in mind — creates undue complications for small residential construction lending. Lenders on small residential projects are not required to accept the statutory partial waiver and subordination form. If a lender on such a project chooses to accept the form voluntarily, however, the result is the same as on a larger project. The lender can opt in, but the statute does not force the issue on small residential work.

The Bottom Line: Know Your Deadlines Before You Need Them

The Massachusetts mechanic’s lien statute is a carefully engineered system with interlocking deadlines, specific notices, and procedural requirements that must be followed exactly. The rolling lien provisions add another layer of sophistication that requires both contractors and lenders to understand their respective rights and obligations throughout the life of the project.

What I tell clients who do construction work in Massachusetts is simple: you need to know these deadlines before the project starts, not after a payment dispute arises. When the notice of substantial completion gets recorded, the clock starts running immediately. By the time you realize there is a problem, you may already be running out of time. The same is true for lenders — if you are financing a construction project and a notice of contract appears at the registry, understanding exactly what that means for your priority position is not optional.

None of this is designed to be a complete guide to lien enforcement in Massachusetts — this is a broad overview, and the specific facts of any project can change the analysis significantly. If you are dealing with a payment dispute on a Massachusetts construction project, the time to talk to an attorney is now, before the filing windows close.
