Preliminary notices in Louisiana
Subcontractors in Louisiana have no general preliminary notice in our summary, but material and equipment suppliers do: a supplier notice of nonpayment within 75 days after the last day of each month you furnish. Within 75 days from the last day of each month materials were delivered.
Lien filing deadline in Louisiana
If the GC hired you, you have 60 days after completion of the project to record a mechanics lien in Louisiana, about 30 days shorter than the national median of 90 days (counted from last furnishing on a sample job). 1 of the 51 jurisdictions we track have a shorter lien deadline and 48 have a longer one.
If a notice of contract was filed: 30 days after the notice of termination. Otherwise 60 days after substantial completion or abandonment. Verify this with the statute before relying on it.
Note what the clock counts from: completion of the project, not your own last day. A trade that finishes early may have more time than the number suggests, but the completion date is often unclear. The calculator uses your last furnishing date when you leave completion blank, which gives the earlier, safer date.
Deadline to sue on the lien
To keep the lien alive you must sue to enforce it within 12 months after recording the lien. If you record on the last possible day, that is about 425 days after your last day on the job, about 60 days longer than the national median of 365 days. 26 of the 48 jurisdictions we track have a shorter overall time to sue and 21 have a longer one.
Because the clock counts from recording, recording early also moves the lawsuit deadline earlier.
How Louisiana compares
Days are counted on a sample job with the lien recorded on its last allowed day, so states that count from recording or from completion can be compared with those that count from your last day on site. The median is across the jurisdictions with a dated rule on file.
- Record the lien (from last day)
- Louisiana: 60 daysNational median: 90 days
- Sue to enforce (from last day)
- Louisiana: 425 daysNational median: 365 days
Public and federal projects
Public property can't be liened, so subcontractors and suppliers on state and local public jobs in Louisiana claim against the GC's payment bond instead. We haven't reduced Louisiana's bond claim deadlines to one set of numbers, because they vary by agency and project. The governing law is La. Rev. Stat. 38:2241 to :2248. Verify the notice and suit deadlines with the statute and the bond itself before the job starts.
Federal jobs in Louisiana follow the Miller Act instead of state law: those hired by a sub or supplier give the prime contractor notice within 90 days of their last furnishing, and suit is due within 1 year, in federal court. Prime contractors on federal work have no lien or bond claim.
Retainage and prompt payment in Louisiana
On public work the cap is 10%, above the 5% median of states that set one. 10% on contracts under $500,000; 5% on contracts of $500,000 or more.
On private work we have no statutory cap on file, so retainage is usually whatever the contract says. Read the retainage and release clauses before you sign.
| Public work | Private work | Federal work | |
|---|---|---|---|
| Retainage cap | 10% | Verify | 10% |
| Release | After acceptance and the 45-day lien period, with a clear lien certificate. | Verify with state statute | Released with final payment, or earlier once progress is satisfactory. |
| GC pays subs within | Verify | Verify | 7 days |
| Late-payment interest | Verify | Verify | Treasury prompt payment rate (reset every January and July) |
Not legal advice. Retainage and prompt payment rules differ by agency, contract size and contract date, and change often. Confirm the rules with the current statute, your contract and a construction attorney before relying on them.
Worked example: a flooring sub in Louisiana
A flooring subcontractor hired by the GC on a private restaurant fit-out in Louisiana starts work on March 2, 2026 and last furnishes on July 17, 2026. The project is completed on August 28, 2026. Run through Louisiana's rules, those dates give:
| Deadline | Date | Counted from |
|---|---|---|
| Record the lien | October 27, 2026 Verify | Project completion |
| Sue to enforce the lien | October 27, 2027 | Lien recording |
The first deadline on the calendar is “Record the lien” on October 27, 2026.
Rows marked "Verify" depend on facts or readings we can't settle for you. Check them against La. Rev. Stat. 9:4801 to :4855.
Because Louisiana counts from project completion (August 28), not the sub's last day (July 17), the lien deadline is later than a last-furnishing state would give.

Not legal advice. Lien and bond claim rules change and have exceptions for project type, contract terms and how notices are served. Confirm every deadline with the current statute or a construction attorney in the project's state before relying on it. Rules shown as "Verify with state statute" have exceptions or variations we could not reduce to one number.
