The Scale of the Unpaid Work Problem in U.S. Construction
The 2024 Construction Payment Report published by Levelset and Procore surveyed more than 3,000 construction professionals across the United States and found that 83 percent of contractors reported at least one significant payment problem in the prior year. Of those, 42 percent said the unpaid amounts materially affected their business operations — causing cash flow problems, delaying payroll, or forcing cutbacks in hiring and equipment. The Foundation for American Contract Contractors estimates the construction industry permanently fails to collect between $40 billion and $50 billion per year. Applied against total annual U.S. construction output of approximately $2.1 trillion, this represents a permanent loss rate of roughly 2 to 2.4 percent of all revenue generated. That average masks enormous variation by state. States with strict preliminary notice requirements produce higher forfeiture rates because more contractors inadvertently miss the notice window and permanently destroy their lien rights before the payment dispute even begins. States with short enforcement windows produce losses among contractors who file the lien correctly but then wait too long to take the next step.
Methodology: How We Ranked the States
Our ranking combines three independent data inputs to produce a composite estimate of annual contractor losses by state. First, annual construction volume from the U.S. Census Bureau Annual Survey of Construction (2023), including residential, nonresidential, and public construction. Higher-volume states produce higher absolute dollar losses even at identical loss-rate percentages. Second, a forfeiture risk score on a 1-10 scale measuring the legal complexity and procedural danger of each state's mechanics lien system, based on: strictness of preliminary notice requirements (days to serve, consequences of a missed or late notice); length of the lien filing window; length of the enforcement window after recording; and presence of acceleration traps that can dramatically shorten deadlines once triggered by an owner action. Third, an adjusted loss rate applying the FACC base permanent loss rate of 2.2 percent of annual construction volume, with a 1.2x multiplier for states with forfeiture risk scores of 8.0 or above and a 0.9x multiplier for states with scores below 6.0.

California: Why It Leads All States in Contractor Losses
California's ranking at the top reflects a convergence of factors found nowhere else in the country. It has the largest construction market by output volume, the strictest preliminary notice deadline in the nation at 20 days from first furnishing under California Civil Code Section 8204, and a 90-day enforcement window after recording the lien — one of the shortest nationally. If a subcontractor misses California's 20-day preliminary notice window, a late notice only protects work performed in the 20 days before the notice was sent. On a project where a subcontractor has been working for 90 days before discovering a payment problem, missing the initial 20-day notice destroys lien rights on 70 days of work — potentially hundreds of thousands of dollars. The California notice also requires accurately naming the construction lender, which catches many contractors who did not know there was a lender or who listed the wrong entity. California's combination of volume, notice strictness, and short enforcement window earns it a forfeiture risk score of 9.4 out of 10.
Texas: The Most Complex Preliminary Notice System
Texas earns a forfeiture risk score of 9.1 for one primary reason: it has the most procedurally complex mechanics lien system in the United States. Texas requires subcontractors and suppliers to send written notice of unpaid invoices to the property owner and general contractor by the 15th of the month following each month in which the work was performed — and this notice must continue every month throughout the project. Miss a single month and you forfeit lien rights for that month's work. A subcontractor on a 10-month Texas project who forgets to send the August notice permanently loses lien rights for all August invoices. The lien filing deadline in Texas is also tied to calendar months rather than days from last furnishing. A general contractor whose last work falls in August has until November 15th to file. A subcontractor with August as their last month must file by October 15th. Miss either date and the right to file is permanently extinguished. Texas does offer a 2-year enforcement window after recording, which prevents the enforcement deadline losses that compound California's problems.
Arizona: The Hidden High-Risk Market
Arizona ranks #9 by total estimated dollar losses but its forfeiture risk score of 8.7 makes it one of the two most procedurally dangerous states on this list, behind only California. Arizona requires a Preliminary 20-Day Notice under A.R.S. § 33-992.01 for subcontractors and material suppliers — as strict as California's 20-day deadline. Miss it and you permanently waive all lien rights for work performed before the 20-day window preceding your late notice. Arizona's enforcement window of 6 months from recording is also short by national standards. Arizona's construction market has grown rapidly as a destination for semiconductor manufacturing, data center construction, and residential development. As the volume increases, the absolute dollar losses from Arizona's high-risk lien system will grow proportionally.
The Colorado Trap: Enforcement Runs from Last Furnishing
Colorado earns a special mention for a statutory trap that costs Colorado contractors millions annually and is not found in any other state in the same form. Under C.R.S. § 38-22-109, the 6-month enforcement deadline in Colorado runs from the last date of furnishing — not from the date the lien was recorded. In virtually every other state, the enforcement clock starts when you record the lien. In Colorado, it starts when you last worked. A Colorado contractor who last works on June 1, negotiates for three months, and finally records their lien on September 1 has only three months left to file a foreclosure lawsuit — because the 6-month clock from last furnishing has already been running since June 1. Contractors who record their Colorado lien at or near the 4-month filing deadline may have almost no enforcement window left by the time the lien is on record. The Mechanics Lien Management State System calculates both Colorado deadlines based on last furnishing date so you always know how much enforcement time you have remaining.
The Preliminary Notice Correlation
One of the clearest findings in this analysis is the correlation between strict preliminary notice requirements and higher estimated annual losses. Of the five states with the highest estimated losses, four have mandatory preliminary notice requirements with deadlines of 60 days or less from first furnishing. Preliminary notice requirements create a deadline that fires at the beginning of every project — often before the contractor has any reason to suspect a payment problem. A subcontractor who starts work in good faith and does not send a California preliminary notice because the relationship seems solid has permanently waived lien rights within 20 days of starting work. The notice requirement does not care about the quality of the relationship or the strength of the contractor's invoice documentation. Data from the Levelset 2024 survey shows that contractors in states with mandatory preliminary notice requirements who consistently sent notices reported payment disputes escalating to nonpayment at a rate 31 percent lower than contractors in the same states who did not. The act of sending the notice — even before any dispute exists — demonstrably reduces the frequency of nonpayment events. The Mechanics Lien Management Method treats preliminary notice as a universal best practice regardless of whether a state requires it. Even in states like Illinois, New York, and Pennsylvania where no notice is legally required, sending one creates a payment culture on the project that correlates with faster payment and fewer disputes. Reference The Mechanics Lien Management State System to generate the correct preliminary notice form for your state and track all deadline windows from day one of every project.
Frequently Asked Questions
Which state has the highest contractor unpaid work losses?
California leads all states in estimated annual contractor losses from unpaid work, with an estimated $9.2 billion in permanently uncollected payments each year. California's enormous construction market — the largest in the country at approximately $298 billion annually — combined with the strictest 20-day preliminary notice deadline in the nation and a 90-day post-recording enforcement window drives higher forfeiture rates than any other state. Texas is second at an estimated $7.8 billion annually.
How much do U.S. contractors lose to unpaid work each year?
The construction industry loses an estimated $40 to $50 billion annually to late and permanently unpaid invoices. Approximately 83 percent of contractors report at least one significant payment problem per year, and industry researchers estimate that 2 to 2.4 percent of total annual construction revenue is permanently uncollected each year across all 50 states.
Do states without preliminary notice requirements have lower contractor losses?
Not necessarily. States without preliminary notice requirements — such as Illinois, New York, and Pennsylvania — do eliminate the specific category of forfeiture losses from missed notice deadlines, but they often have other complexity factors. New York's 30-day Section 59 acceleration window is one of the most dangerous enforcement traps in the country even without a preliminary notice requirement. The absence of a preliminary notice requirement reduces one source of forfeiture loss but does not eliminate the systemic payment challenges in construction.
Why does California have such a high contractor payment loss rate?
California's high contractor loss rate results from three converging factors: it has the country's largest construction market by volume ($298 billion annually), the strictest preliminary notice deadline in the nation at 20 days from first furnishing, and a 90-day post-recording enforcement window that is among the shortest nationally. A late California preliminary notice only protects work done in the 20 days before the notice was sent — meaning contractors who miss the initial window lose lien protection for potentially months of work on a long project.
How can contractors reduce unpaid work losses?
The single most effective action is to send a preliminary notice on every project on the first day of work, regardless of whether the state legally requires it. Research consistently shows that contractors who routinely send preliminary notices get paid faster and have fewer disputes escalate to nonpayment. Beyond preliminary notice, use The Mechanics Lien Management State System to track all deadlines — preliminary notice, lien filing, and enforcement — on every project.
What is the forfeiture risk score used in this analysis?
The forfeiture risk score measures the likelihood that a contractor in a given state will permanently lose lien rights due to a procedural error. States are scored on a 1–10 scale based on four factors: strictness of preliminary notice requirements; length of the lien filing window; length of the enforcement window; and presence of acceleration traps that can shorten deadlines dramatically once triggered by an owner action. California scores 9.4, Texas 9.1, and Arizona 8.7 — the three most procedurally dangerous states in the country.
