Preliminary notices in Kentucky

Kentucky is one of the states with no general preliminary notice for subcontractors on commercial work in our summary. That doesn't mean you can skip paperwork: the lien itself still has a hard deadline, and the other notices below still apply.

There is one more step: subcontractors and suppliers give a notice of intent to lien within 120 days after your last day furnishing labor or materials. It is required. Owner-occupied residential: within 75 days.

Lien filing deadline in Kentucky

If the GC hired you, you have 6 months after your last day furnishing labor or materials to record a mechanics lien in Kentucky, about 93 days longer than the national median of 90 days (counted from last furnishing on a sample job). 45 of the 51 jurisdictions we track have a shorter lien deadline and 2 have a longer one.

The clock starts on your last day furnishing labor or materials under your contract. In many states, warranty visits and punch list work done mainly to extend the deadline don't restart it, so use your last day of real contract work.

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 548 days after your last day on the job, about 183 days longer than the national median of 365 days. 36 of the 48 jurisdictions we track have a shorter overall time to sue and 11 have a longer one.

Because the clock counts from recording, recording early also moves the lawsuit deadline earlier.

How Kentucky 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.

Kentucky deadlines vs the national median
Record the lien (from last day)
Kentucky: 183 days
National median: 90 days
Sue to enforce (from last day)
Kentucky: 548 days
National median: 365 days

Public and federal projects

Public property can't be liened, so subcontractors and suppliers on state and local public jobs in Kentucky claim against the GC's payment bond instead. We haven't reduced Kentucky's bond claim deadlines to one set of numbers, because they vary by agency and project. The governing law is Ky. Rev. Stat. §376.195 to .250. Verify the notice and suit deadlines with the statute and the bond itself before the job starts.

Federal jobs in Kentucky 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 Kentucky

We haven't reduced Kentucky's retainage and prompt payment rules to single numbers yet: they depend on the agency, the contract size or the contract date. Rather than guess, the table shows "Verify" and the statutes to read are Ky. Rev. Stat. §371.405 to .425 (prompt pay). Your contract's payment terms still matter, and the federal rules below apply on federal work.

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 painting sub in Kentucky

A painting subcontractor hired by the GC on a private retail shell in Kentucky starts work on March 2, 2026 and last furnishes on July 17, 2026. The project is completed on August 28, 2026. Run through Kentucky's rules, those dates give:

Deadlines for the worked example in Kentucky
DeadlineDateCounted from
Notice of intent to lien November 14, 2026 Weekend Last furnishing
Record the lien January 17, 2027 Weekend Last furnishing
Sue to enforce the lien January 17, 2028 Lien recording

The first deadline on the calendar is “Notice of intent to lien” on November 14, 2026.

2 dates land on a weekend (November 14, 2026, January 17, 2027). Not every state rolls a deadline to Monday, so the safe move is to record or serve by the Friday before.
