The first American mechanics lien law came out of a meeting in 1791, 235 years ago, attended by Thomas Jefferson and James Madison, who would both later become presidents of the United States. This is the story of how that idea was born, how it spread across the country, and how it still protects construction companies' right to get paid, especially in California, where it's written into the state constitution.

Every builder knows the oldest risk in the trade: you finish the work, and the check never comes. In California, the answer to that risk is written into the state constitution. If you improve a property, you have the right to put a lien on it. But the right is fragile. Miss one date, whether it's 20 days to serve a preliminary notice, as few as 30 days to record a lien, or 90 days to sue, and it's gone. The problem is as old as the country. In 1791, the men building Washington, D.C. were trying to solve it too.

A meeting in Georgetown

On August 28, 1791, Secretary of State Thomas Jefferson wrote to the three commissioners running the new capital on the Potomac: Thomas Johnson, David Stuart, and Daniel Carroll. He and James Madison, he told them, planned to pass through Georgetown on their way home to Virginia, and they would sit in on the commissioners’ meeting on September 8.

There the group adopted a memorial, a formal petition, to the Maryland General Assembly. Among other things, it asked for something new in American law. As quoted in a 1977 Maryland Law Review article, the memorialists wrote that “it would encourage master builders to contract for the erecting and finishing houses for certain prices, agreed on, if a lien was created by law for their just Claim on the house erected and the lot of ground on which it stood.”

The reasoning was a builder’s reasoning. The new city needed houses. Under the common law of the time, an unpaid builder could sue, but that gave him no claim on the building itself. Lots were being sold to buyers and investors from all over, and a carpenter or bricklayer had little reason to put his labor and materials into a house for an owner he might never find again. A lien would make the building itself security for the bill.

December 19, 1791: the first mechanics lien law

Maryland moved fast. On December 19, 1791, about three months after the Georgetown meeting, the General Assembly passed “An Act concerning the territory of Columbia and the city of Washington” (1791 Md. Laws, ch. 45). Section 10 is the part construction lawyers still talk about.

It opened with its purpose: “for the encouragement of master builders to undertake the building and finishing houses within the said city, by securing to them a just and effectual remedy for their advances and earnings.” It then gave the “undertaker, or workmen” who built a house in the city, or did “the brick work, or carpenters or joiners work thereon,” a lien on “the house and the ground on which the same is erected,” including the materials they supplied.

This is generally recognized as the first mechanics lien law in the United States. The lien covered only written contracts. Those contracts had to be acknowledged before a commissioner, a justice of the peace, or a Georgetown alderman, and recorded within six calendar months. The builder had to go to court within two years after the last of the work was done. From its first day, America’s lien right came with paperwork and a clock.

The idea travels

From Maryland, the idea moved north. Pennsylvania approved its first lien law for buildings on April 1, 1803. It covered Philadelphia and the neighboring districts of Southwark and the Northern Liberties, and legal historians call it the second in the nation. In 1847, in Bolton v. Johns, Pennsylvania Chief Justice John Bannister Gibson explained why the state had acted. It was, he wrote, “the frequency of loss sustained by mechanics and dealers” working for owners through hired builders that “first induced the legislature to give them a lien on the building.”

By mid-century the idea had reached the Pacific. On April 12, 1850, before California was even admitted to the Union, its first Legislature passed a mechanics lien statute that covered “master builders, mechanics, lumber merchants, and all other persons performing labor or furnishing materials.”

In Walker v. Hauss-Hijo, decided by the California Supreme Court in December 1850, a lumber merchant lost his lien because he missed the statute’s 60-day window, after the building was completed, to file notice of his lien with the county recorder. California’s lien law was less than a year old, and a deadline was already deciding who got paid.

California puts it in the Constitution

California then went further than most states. When it rewrote its constitution in 1879, it made the lien a constitutional right. Article XX, Section 15 read:

“Mechanics, material men, artisans, and laborers of every class, shall have a lien upon the property upon which they have bestowed labor or furnished material for the value of such labor done and material furnished; and the Legislature shall provide, by law, for the speedy and efficient enforcement of such liens.”

A 2000 California Law Revision Commission staff memorandum calls the mechanics lien “the only creditor’s remedy set out in the state constitution.” In 1974 the wording was updated (“persons furnishing materials” replaced “material men”), and in 1976 the provision was moved to Article XIV, Section 3, where it sits today. The substance hasn’t changed. If you improve the property, you have a lien right, and the Legislature decides how you enforce it.

Why a constitutional right still runs on deadlines

That last clause matters. The Constitution gives you the right. The Civil Code tells you how to keep it, and its rules are strict. Under California’s current statutes for private works:

Preliminary notice: 20 days. Most subcontractors and suppliers must serve a preliminary notice within 20 days after they first furnish work (Civ. Code §§ 8200, 8204). If you serve it late, you can usually still lien, but only for work you furnished within the 20 days before the notice and after. Direct contractors who contract with the owner generally owe a preliminary notice only to the construction lender, if there is one. Laborers are exempt.
Recording the lien: 90, 60, or 30 days. A direct contractor must record its claim of lien after completing its contract, and before the earlier of 90 days after the project is completed or 60 days after the owner records a notice of completion or cessation (§ 8412). Subcontractors and suppliers must record after they stop providing work, and before the earlier of 90 days after completion or 30 days after a recorded notice of completion or cessation (§ 8414).
Foreclosure: 90 days. You must file a lawsuit to enforce the lien within 90 days after recording it, or the lien expires and can't be enforced (§ 8460). There's a narrow exception if you and the owner agree to extend credit and record notice of that agreement.

Many contractors also send a Notice of Intent to Lien before recording, as a firm last reminder that a lien is coming if the bill isn't paid.

Missing any one of these dates can cost you a right that the Founders helped create and that Californians wrote into their constitution. The carpenter in 1791 had six months to record his contract. The lumber merchant in 1850 had 60 days. You may have as few as 30.

Keeping the 1791 promise

The commissioners in Georgetown wanted houses built in a new capital. What they left behind was a principle that has outlasted them: people who build should have real security for their “advances and earnings.” What’s changed is how many deadlines you have to track, often across a dozen jobs at once.

That's the reason we built FieldLatch. It helps California contractors prepare and send preliminary notices and Notices of Intent, file mechanics liens, and keep track of the dates so the paperwork goes out on time. The lien right has been around since 1791. We just help you stay ahead of the calendar.

This post is general information about history and California law. It is not legal advice. Lien rules have exceptions and change over time, so talk to a California construction attorney about your specific project.
