How Do Mechanic's LiensWork in Florida?

Florida's mechanic's lien law is powerful — and unforgiving. Contractors, subcontractors, and suppliers who go unpaid have the right to place a lien on the property they improved. But the deadlines are strict, the notice requirements are technical, and missing a step can cost you the right to collect entirely.

What Is a Mechanic's Lien?

A mechanic's lien (also called a construction lien in Florida) is a legal claim against real property filed by a contractor, subcontractor, laborer, or material supplier who provided work or materials to improve that property and was not paid. The lien attaches to the property itself — which means it can prevent a sale or refinancing until the debt is resolved.

Who Can File a Lien in Florida?

Under Florida Statute § 713, the following parties have lien rights:

• General contractors who have a direct contract with the property owner
• Subcontractors hired by the general contractor
• Sub-subcontractors
• Material suppliers who furnish materials to the job
• Laborers who perform work on the project
• Architects, engineers, surveyors, and landscape architects

Importantly, lien rights extend even to parties who don't have a direct relationship with the property owner — as long as proper notice procedures are followed.

The Notice to Owner Requirement

This is where most lien claims fail. Any party who does not have a direct contract with the property owner must serve a Notice to Owner (NTO) to preserve their lien rights. The NTO must be served:

• No later than 45 days after first furnishing labor or materials to the project
• By certified mail or personal delivery to the owner and the general contractor
• Before the owner pays the general contractor in full

Miss the 45-day window, and your lien rights are gone — even if you're owed thousands of dollars. General contractors who contract directly with the owner don't need to serve an NTO, but they must still meet other deadlines.

Filing the Lien: Critical Deadlines

Once the project is complete (or you stop furnishing labor/materials), the clock starts on filing the lien itself:

• The lien must be recorded in the county where the property is located within 90 days of the last date you furnished labor or materials
• A copy of the recorded lien must be served on the owner within 15 days of recording
• If the lien is not enforced (through a lawsuit) within 1 year of recording, it expires

These are hard deadlines — there is no grace period and no exceptions for not knowing the rules.

Enforcing a Lien Through Foreclosure

Recording a lien doesn't get you paid automatically. To actually collect, you must file a lien foreclosure lawsuit in circuit court within one year of recording. This lawsuit asks the court to force a sale of the property to satisfy the lien. In practice, many liens are resolved through negotiated payment before foreclosure becomes necessary — the threat of a lien affecting a property sale is a powerful motivator.

Defending Against a Lien (For Property Owners)

If a lien has been filed against your property, you have options:

• Transfer the lien to a bond — post a bond in the amount of the lien plus interest, which releases the property from the lien while the dispute continues
• Contest the lien's validity — if proper procedures weren't followed, the lien may be unenforceable
• Negotiate a release — resolve the payment dispute and obtain a lien release
• File a Notice of Contest of Lien — shortens the enforcement window to 60 days, forcing the lienor to act quickly or lose the lien

Whether you are a contractor who hasn't been paid or a property owner disputing a lien, the procedural requirements under Florida's construction lien law are intricate. An attorney experienced in construction disputes can mean the difference between getting paid and losing your claim entirely.
