Why Priority Decides Whether a Mechanics Lien Is Worth Anything
A mechanics lien is a security interest in real property, and when the property is sold at foreclosure the proceeds are distributed in order of priority: the first lienholder in line is paid in full before the second receives a dollar. On a distressed construction project the numbers are rarely close. A stalled development might carry a 12 million dollar construction mortgage against a property worth 9 million at auction, and every lien junior to that mortgage — every subcontractor, supplier, and equipment lessor on the job — recovers nothing regardless of how meritorious the underlying debt is. Reverse the priority and the economics reverse with it. If the project's liens relate back to a commencement date that precedes the mortgage, the lender becomes the junior creditor and faces a foreclosure that would wipe out its own security. Lenders in that position do not litigate to a sale; they negotiate, and they pay. This is why relation back matters more to an unpaid contractor than almost any other feature of lien law: it converts a claim against an insolvent general contractor into a senior claim against real estate that a solvent institution is highly motivated to protect. Priority is also why lien law is written the way it is. A mechanics lien exists because a contractor's labor and materials physically increase the value of the owner's property, and the law regards it as unjust for a lender to capture that added value ahead of the people who created it.
The Four Priority Models Across the 50 States
Mechanics lien priority against a construction mortgage falls into four models. The commencement-of-work model, used in 32 states, gives every claimant on a project one shared priority date fixed by the first visible work on the ground; any mortgage recorded afterward is subordinate, and liens generally rank equally among themselves rather than in filing order. The claimant's-first-furnishing model, used in seven states including Iowa, Indiana, Kentucky, New Hampshire, North Carolina, Washington, and West Virginia, gives each claimant its own priority date based on when that claimant started work, so an early subcontractor can outrank a mortgage that outranks a later subcontractor on the same job. The date-of-recording model, used in eight states, is a pure race in which the lien takes priority only from the moment it is recorded. A fourth group fixes priority by a recorded or filed paper event rather than by physical work: Illinois uses the owner-contractor contract date, Florida the recorded Notice of Commencement, Utah the first preliminary notice filed on the State Construction Registry, and Massachusetts the recorded Notice of Contract.
The 29 States Where the Mechanics Lien Beats the Bank
In 29 states the answer is a clean yes: work commenced, the lender recorded afterward, and the lien takes the senior position. Nevada states the rule most bluntly — under NRS 108.225 every lien is preferred to any mortgage or encumbrance attaching after commencement of the work of improvement, regardless of when the lien notices were recorded. Montana goes further: under Mont. Code Ann. section 71-3-542(4) a construction-financing mortgage is subordinated even if it was recorded before the lien attached. California Civil Code section 8450 relates priority back to the visible commencement of the work of improvement as a whole. Texas Property Code sections 53.123 and 53.124 speak of the inception of the lien, which attaches at visible commencement or delivery of materials, and Texas original contractors additionally hold a self-executing constitutional lien. Virginia Code section 43-21 is the most explicit of all: an encumbrance created after work commenced is subordinate even if it was recorded before the memorandum of lien. Missouri's section 429.060 is the classic first-spade rule. Minnesota and South Dakota key priority to the actual and visible beginning of the improvement on the ground, and Michigan to the first actual physical improvement. Alabama, Arkansas, Colorado, Connecticut, Georgia, Hawaii, Idaho, Kansas, Louisiana, Nebraska, New Mexico, Ohio, Oklahoma, Oregon, Tennessee, Wisconsin, and Wyoming round out the group. North Carolina and West Virginia reach the same destination on a claimant-specific route, relating the lien back to the date that particular claimant first furnished labor or materials.
The Seven Pure Race States Where the Recorded Mortgage Always Wins
Seven states reject relation back entirely. In Alaska, Maryland, Massachusetts, Mississippi, New Jersey, New York, and Rhode Island, mechanics lien priority is a recording race, and a construction mortgage recorded before the lien claim takes the senior position no matter how long the contractor had been on site. New York is the most economically significant: Lien Law section 13 fixes priority at the date the notice of lien is filed, with no relation back to commencement, and a building-loan mortgage retains priority for advances made before the filing where it carries the statutory trust-fund covenant. New Jersey's N.J.S.A. section 2A:44A-22 preserves a prior mortgage's priority for funds advanced or committed before the lien claim was filed. Massachusetts dates priority from the recording of the Notice of Contract under chapter 254 section 7. Mississippi is the most recent convert, installing a pure filing-date rule at section 85-7-405(2) in its 2014 lien-act rewrite. Alaska's AS 34.35.060 runs the same race with a narrow exception for individual laborers on original construction, and Rhode Island dates priority from the filing of the notice of intention. Maryland is structurally different from every other state: a Maryland mechanics lien is not inchoate and does not exist until a court establishes it after a show-cause hearing, so any mortgage recorded before the court acts has priority as a matter of course.
The Lender Carve-Outs: 14 States That Split the Difference
Between the two poles sits a group of 14 states that relate lien priority back to work and then hand the construction lender a narrow statutory shield. These carve-outs are where contractors are most often surprised, because the general rule suggests the lien should win while the exception quietly reverses the outcome. Arizona runs the cleanest version: A.R.S. section 33-992 relates priority back to visible commencement, but a lender's deed of trust recorded within ten days after commencement takes priority over the project's liens, and on day eleven the shield disappears. Pennsylvania's 49 Pa. Stat. section 1508 subordinates the lien to purchase-money mortgages and to open-end construction mortgages where at least sixty percent of the loan proceeds fund the work, which describes most real construction loans. Delaware protects a first construction mortgage where at least fifty percent of proceeds pay for labor and materials. Kentucky imposes a trap that rewards preparation: under KRS 376.010 the lien will not prime a later-recorded mortgage unless the claimant pre-filed a statement of intent with the county clerk before the mortgage recorded. Maine conditions priority on the lender having consented to or known of the work, and North Dakota expressly protects a good-faith construction loan unless the lien recorded first. Iowa defeats the intuition that relation back is project-wide: under Iowa Code section 572.18 priority turns on whether that specific claimant commenced its own particular work before the mortgage recorded, so two subcontractors on the same project can land on opposite sides of a single mortgage. Indiana sorts the question by project type, protecting the lender on commercial projects while exempting Class 2 residential structures. Vermont, New Hampshire, South Carolina, and Washington each protect construction financing to the extent of its advances while leaving the lien senior as to the improvement's value or post-notice disbursements.
What Counts as Commencement of Work, and Why Contractors Must Prove It
In 32 states the priority date is a question of fact, which means somebody has to prove it, sometimes years later in a foreclosure action where a bank's recovery depends on the answer. The statutes converge on a demanding standard: the work must be visible, and it must be an actual beginning of the improvement rather than preparation for one. The exclusions matter more than the inclusions. Minnesota's section 514.05 expressly discounts staking, surveying, and soil testing, and Michigan's section 570.1119 excludes surveying and soil boring from the first actual physical improvement. A contractor who believes the clock started when the surveyors arrived may find the priority date reset weeks later to the first excavation, conveniently for the lender, after the mortgage recorded. Idaho cuts the other way and is the most generous in the country: under Idaho Code section 45-506 the relation-back date can be triggered by professional services such as the preparation of plans or a survey, well before any ground is broken. The evidentiary consequence is concrete. A contractor whose priority depends on a March commencement date should hold timestamped photographs of the first visible work, dated delivery tickets for the first materials, the first signed daily report, and dated equipment mobilization records. These documents cost nothing to keep at the time and are close to impossible to reconstruct later.
The Paper-Event States and What This Means for Contractors
Four states do not tie the priority date to physical work at all, which means a contractor can lose priority without anyone ever disputing when the first shovel moved. Illinois is doctrinally unique: under 770 ILCS 60/1 the lien attaches as of the date of the owner-contractor contract, and under 770 ILCS 60/16 a prior encumbrancer retains priority as to the value of the land while the mechanics lien primes as to the value of the subsequent improvements, so an Illinois lien and an Illinois mortgage can each win on different slices of the same property. Florida keys priority to the recording of the owner's Notice of Commencement under section 713.07(2), which means Florida contractors have no direct control over their own priority date. Utah relates priority back to the date of the first preliminary notice filed on the State Construction Registry rather than to physical commencement, making early preliminary notice filing a priority strategy rather than a compliance step. Massachusetts dates priority to the recorded Notice of Contract. The lesson across all four is the same: where a document fixes priority, file it at the earliest moment the statute allows, not on the last permissible day. Three takeaways follow from the whole dataset. Most unpaid contractors hold more leverage than they realize, because in 29 states the lien is senior to the construction mortgage on the ordinary fact pattern. The priority date is evidence, not paperwork, and must be documented while the job is running. And priority and timeliness are independent obligations: a senior priority date does nothing for a lien recorded after the filing deadline expired, and a perfectly timely lien is worth little in Maryland or New York if the bank recorded first. The Mechanics Lien Management State System tracks preliminary notice, filing, and enforcement deadlines for every project across all 50 states.
Frequently Asked Questions
Does a mechanics lien have priority over a mortgage?
In most of the country, yes — if work commenced before the mortgage was recorded. Thirty-two states apply a relation-back rule under which every mechanics lien on a project takes its priority date from the visible commencement of work, not from the day the lien document was recorded. In 29 states a properly perfected lien can therefore prime a construction mortgage that was recorded before the lien was filed, so long as the first shovel went into the ground before the lender recorded. Seven states — Alaska, Maryland, Massachusetts, Mississippi, New Jersey, New York, and Rhode Island — apply a pure recording race in which a mortgage recorded before the lien wins regardless of when construction began. The remaining states give lenders partial protection through statutory carve-outs.
What does relation back mean in mechanics lien law?
Relation back means the lien's priority date is earlier than the date the lien was actually recorded. In a relation-back state, a lien recorded in October may take its priority from the March morning when excavation first became visible on the site. Every claimant on the project — the general contractor, every subcontractor, and every supplier — shares that single project-wide commencement date, which is why liens in these states generally rank equally among themselves rather than in the order they were filed. The practical consequence is that a construction lender who records a mortgage in April, after visible work began in March, takes a subordinate position to liens that did not yet exist on paper. This is why title companies inspect a site for evidence of work before insuring a construction loan.
Which states let the bank beat a mechanics lien?
Seven states apply a pure recording race in which the first document recorded wins: Alaska, Maryland, Massachusetts, Mississippi, New Jersey, New York, and Rhode Island. In these states there is no relation back to the start of construction, so a construction mortgage recorded before the lien claim or notice of lien has priority even if the contractor had already been working for months. Mississippi adopted this rule in its 2014 lien-act rewrite, and Maryland goes furthest of all because a Maryland mechanics lien does not exist until a court establishes it after a hearing. A further fourteen states subordinate the lien to construction mortgages only partially, protecting the lender through specific statutory carve-outs rather than a flat recording race.
What is the Arizona 10-day rule for mechanics lien priority?
Arizona relates lien priority back to the visible commencement of work under A.R.S. section 33-992, but it gives construction lenders a narrow grace period. A lender's deed of trust recorded within ten days after commencement of work takes priority over the mechanics liens on the project. Recorded on day eleven or later, the deed of trust is subordinate and the liens prime it. Arizona is the clearest example of a broader pattern: several relation-back states pair a contractor-friendly priority date with a targeted exception that protects a construction loan. Pennsylvania subordinates the lien to an open-end construction mortgage where at least sixty percent of the proceeds fund the work, and Delaware protects a first construction mortgage where at least fifty percent of proceeds pay for labor and materials.
How does a contractor protect lien priority against a construction lender?
Document the commencement date, because in 32 states that date is the lien's priority date and it is a question of fact the contractor may have to prove years later. Photograph the first visible work with a timestamp, keep dated delivery tickets for the first materials, and retain the first signed daily report. Understand that staking, surveying, and soil testing do not count as commencement in states such as Minnesota and Michigan, which require an actual and visible beginning of the improvement on the ground. In the seven pure race states, priority turns on recording instead, so the lien or notice must be recorded as early as the statute permits rather than at the deadline. Kentucky requires a claimant to pre-file a statement of intent with the county clerk before the mortgage records in order to prime it, and Utah keys priority to the first preliminary notice filed on the State Construction Registry rather than to physical work.
