The 60-second version

A mechanic's lien (formally construction lien in Florida) is a legal claim that a contractor, sub-contractor, or material supplier can place on your property if they're unpaid for work performed. Governed by F.S. Chapter 713. To protect yourself, file a Notice of Commencement (NOC, F.S. §713.13) at project start; require Releases of Lien partial and final at each progress payment (F.S. §713.20). Sub-contractors and suppliers have 90 days after last work to record a Claim of Lien. The lien must then be perfected via court action within 1 year.

Definition and who can lien

  • Construction lien = encumbrance recorded in county records against your property.
  • May lien (F.S. §713.01):
    • Direct contractor (whom you have contracted with).
    • Sub-contractor (hired by your contractor).
    • Sub-sub-contractor (max one extra level).
    • Material supplier (selling to your project).
    • Architect, engineer, surveyor licensed.
  • Cannot: unlicensed contractor (F.S. §489.128).

Notice of Commencement (NOC) — F.S. §713.13

  • Document you (owner) record in county records before work begins.
  • Lists: property description, main contractor, surety (if any), project description, date.
  • Must be posted at the job site or available there.
  • Validity: 1 year (renewable).
  • Effect: any sub-contractor or supplier wanting to lien must send you a Notice to Owner (NTO, F.S. §713.06) within 45 days of their first delivery. Without NTO, they lose lien rights.
  • Essential for any project ≥ $2,500.

Releases of Lien at each payment

  • Before paying each progress draw, demand from the contractor:
    • Partial Release of Lien from the contractor for the paid tranche.
    • Partial Release of Lien from each listed sub-contractor and supplier.
  • Before final payment:
    • Final Affidavit from contractor (F.S. §713.06(3)(d)) listing all subs/suppliers and their status.
    • Final Releases of Lien from all listed.
  • No releases = payment held until cleared.

Claim of Lien: timeline

  • Unpaid sub or supplier has 90 days after their last work to record a Claim of Lien (F.S. §713.08).
  • Must then, within 1 year, file a foreclosure suit in circuit court to perfect the lien (F.S. §713.22).
  • Owner can force quick resolution by sending a 20-day notice to the lien-holder, who must sue within 20 days or the lien expires (F.S. §713.21(2)).
  • Lien removed: by payment, settlement, or expiry.

For Canadians: protection

  • Always file NOC before any project ≥ $2,500.
  • Always require Releases of Lien before paying.
  • Keep all receipts and lists of sub-contractors.
  • If you receive an NTO (Notice to Owner) from a sub: keep carefully, it's a signal a lien may follow.
  • If lien is placed: don't panic, contact a FL construction attorney. Several quick remedies (transfer to bond F.S. §713.24, 20-day notice, etc.).
  • Lien on the property blocks any future sale until cleared.
