A mechanic's lien is a security interest in the title to property for the benefit of those who have supplied labor or materials that improve the property. The lien exists for both real property and personal property. In the realm of real property, it is called by various names, including, generically, construction lien. It is also called a materialman's lien or supplier's lien when referring to those supplying materials, a laborer's lien when referring to those supplying labor, and a design professional's lien when referring to architects or designers who contribute to a work of improvement. In the realm of personal property, it is also called an artisan's lien. The term "lien" comes from a French root, with a meaning similar to link; it is related to "liaison." Mechanic's liens on property in the United States date from the 1700s.
With respect to real property, mechanic's liens are purely statutory devices that exist in every state (although in one state, as noted below, they have a constitutional foundation). The reason they exist is a legislative public policy to protect the contractors. More specifically, the state legislatures have determined that, due to the economics of the construction business, contractors and subcontractors need a greater remedy for non-payment for their work than merely the right to sue on their contracts. In particular, without the mechanics' lien, subcontractors providing either labor or materials may have no effective remedy if their general contractor isn't sufficiently financially responsible because their only contractual right is with that general contractor.
Without the mechanic's lien, the contractor would have a limited number of options to enforce payment of the amounts owed. Further, there is usually a long list of claimants on any failed project. To avoid the specter of various trades, materialmen and suppliers attempting to remove the improvements they have made, and to maintain a degree of equality between the various lienors on a project, the statutory lien scheme was created. Without it, Tradesperson A may try to "race" Supplier B to the courthouse, the project site or the construction lender to obtain payment. Most lien statutes instead mandate strict compliance with the formalized process they create in return for the timely resolution and balancing of claims between all parties involved - both owners and lien claimants.
In the state of California, mechanic's liens are a constitutional right guaranteed to contractors by the California Constitution.
Mechanic's liens on the title to real property are exclusively the result of legislation. Each state has its own laws regarding the creation and enforcement of these liens, but, overall, there are some similar elements among them.
Real property of the government (public property) is ordinarily not subject to the claims of private parties. Therefore, unless the state specifically so provides, mechanic's liens do not attach to the title owned by the state or its administrative subdivisions, such as cities. Similarly, mechanic's liens under state law are invalid on federal construction projects. To protect subcontractors and suppliers federal projects, where the contract price exceeds $100,000.00, the Miller Act[5] requires general contractors to provide a surety bond which guarantees payment for work done in accordance with the terms of the contract. Many state and municipal governments similarly require contractors on public works projects to be bonded.
Creation and perfection
Under the statutes, the lien is usually created by the performance of labor or the supplying of material that improves the property. Just what type of contribution counts as a valid basis for a mechanics lien varies, depending on the particular state statute that applies. Some common examples are:
Laborers, carpenters, electricians, mechanical/HVAC contractors and plumbers working on the project site;
Lumber yards, plumbing supply houses and electrical suppliers;
Architects and civil engineers who drew up the construction plans and specifications; and
Offsite fabricators of specialty items that are ultimately incorporated into the project.
Often, there is no simple dividing line that is useful in every state, or even in every case, for determining this eligibility. Deciding whether a party has a legitimate lien right may depend on examining court cases that have either upheld or rejected lien claims in the same state.
Unlike other security interests, in most states, mechanic's liens are given to contractors and material suppliers who may or may not have a direct contractual agreement with the owner of the land. In fact, this is often the norm because in most cases, the owner of the land contracts only with a general contractor (often called a "prime contractor"). The general contractor, in turn, hires subcontractors ("subs") and material suppliers ("suppliers") to perform the work. These subs and suppliers are entitled to liens on the owner's property to secure their payment from the general contractor.
However, to have an enforceable lien, it usually must be "perfected." This means that the holder of the lien must comply with the statutory requirements for maintaining and enforcing the lien. These requirements, which contain time limits, are generally as follows:
-Providing the required preliminary notice to the property owner disclosing the entitlement to the lien (some states).
-Filing notices of commencement of work (some states).
-Filing notices in the required public records offices of the intention to file a lien if unpaid (some states).
-Filing the notice or claim of lien in the required public records offices within a specified period of time after the materials have been supplied or the work completed (all states). The law varies from state-to-state on both the triggering event and the timing of this. Some states require the filing within a period measured from the time when the claimant completes its work, while others specify the event as being after all work on the project has been completed. The filing time periods after the triggering event vary, with 4-6 months being common.
-Filing a lawsuit to foreclose the lien within a specified time period.
