Preliminary Notices and Who Has to Send One
The notice arrives on headed paper from a supplier nobody has heard of, using words like lien and claim, and homeowners routinely panic. It is the opposite of a demand: it is the document a claimant must send before anything is even owed.
What this report covers
- A preliminary notice is a precondition to a lien claim, not a claim itself and not a sign of a dispute.
- Deadlines run from the date the sender first furnished labor or materials, not from non-payment.
- Requirements vary sharply by state: some require notice from everyone, some only from parties without a direct contract.
- For an owner, the notices collectively map every party who could claim against the property.
- Paying against lien waivers from the parties who served notice is the practical defense.
Three weeks into a kitchen renovation, an envelope arrives from a cabinet supplier the homeowner has never spoken to. It uses the words lien, claim and property, and it looks like the opening move in a dispute. It is not. It is the document that supplier must send before it could ever bring a claim — and it usually arrives while everyone is being paid on time.
What the notice is for
Mechanic's lien systems solve a specific problem. A homeowner contracts with a builder; the builder contracts with subcontractors and suppliers; the homeowner pays the builder in full; the builder does not pay down the chain. Without a lien right, the subcontractor's only remedy is against a builder who has already spent the money.
The lien gives those parties a claim against the property itself. The preliminary notice is the price of admission: it tells the owner that a party is working on their property and that they intend to preserve the right to claim if they are not paid. Serve it and the right survives; miss the deadline and, in most states, it does not.
For an owner, the notices that arrive over the first weeks of a project are the most useful document set the project produces. They name every party who could claim against the property, which is exactly the list you need in order to collect waivers as you pay.
Who has to send one
The rules are state-specific and the differences matter:
| Party | Common position | Why |
|---|---|---|
| Subcontractors | Notice required in most states | No direct contract with the owner |
| Material suppliers | Notice required in most states | Owner has no way of knowing they exist |
| Equipment lessors | Often required, sometimes excluded | Depends on whether rental counts as furnishing |
| General contractor | Required in some states, not in others | Owner already knows who they hired |
| Design professionals | Varies widely | Some states treat design as lienable, some do not |
The deadline is the part that ends claims. It runs from first furnishing — the day the party first supplied labor or materials to the project — and not from the day an invoice went unpaid. A supplier who delivers in March and is unpaid in August has almost always missed the window if they waited for the non-payment to prompt them.
Service requirements are formal: certified or registered mail in most states, to the owner and frequently also to the general contractor and any construction lender, at addresses that have to be correct. A notice sent to the wrong entity or by the wrong method fails even though it was sent on time.
What an owner should do with one
- Keep it. File every notice with the project papers rather than discarding it as junk mail.
- Build the list. Each notice adds a party to the set of people who must sign a waiver before you release the payment covering their work.
- Ask your contractor to reconcile it. A notice from a supplier the contractor claims not to be using is worth a conversation before the next payment.
- Pay against waivers. Conditional waiver on progress payment, unconditional waiver once the payment clears — the standard four forms exist in most states for exactly this sequence.
- Consider joint checks where a supplier is large relative to the job, so the money reaches them directly.
The reason this matters is double payment. In most states an owner who has paid the general contractor in full can still face a valid lien from an unpaid subcontractor, and the owner's remedy is against a contractor who has already failed. The waiver process is the only reliable defense, and it depends on knowing who to collect waivers from — which is what the notices tell you.
For the party serving the notice
From the claimant's side the discipline is simple and frequently neglected. Serve on the first furnishing date rather than when payment becomes doubtful. Serve on every project as a matter of routine, so the decision is never made project by project. Keep proof of service with the job file, because the proof is what a later claim rests on. And diary the subsequent deadlines — the lien filing period and the period for enforcing it are separate, shorter, and equally fatal.
On public projects the lien route is usually unavailable, because public property cannot be liened. The substitute is a claim against the payment bond, with its own notice requirements and its own clock, and confusing the two regimes is a common way to lose a claim on a public job.
How the chain actually resolves
Most notices lead nowhere, which is the system working. Where they do lead somewhere, the sequence is: notice, then a recorded lien within the statutory period, then an action to enforce it within a further period, then either payment, a bond substituting for the lien, or a foreclosure action.
For an owner, the leverage sits earlier than any of that — in the amount still held back when the dispute starts, and in whether the contractor was licensed and bonded in the first place. An owner holding nothing back, dealing with an unlicensed builder, facing three notices from unpaid suppliers, has no good options left; the same owner holding ten percent and a stack of signed waivers has very few problems.
Owners should read the notices against the permit record as well as the payment schedule. A claimant who served notice for work that never passed its inspection stage is asserting a right to be paid for something the building department has not yet accepted.

Questions readers ask
I received a notice but I have paid everything. Should I worry?
Not on its own. A preliminary notice is sent early and routinely, usually to every project the sender works on, and it signals nothing about payment. What it does tell you is that this party has preserved the right to claim if they are not paid — including if your contractor takes your money and does not pass it down. That is precisely the risk a lien waiver at each payment addresses.
Does a general contractor have to send one?
It depends on the state. Several require a preliminary notice from everyone including the direct contractor; others require it only from parties with no direct contract with the owner, on the reasoning that the owner already knows about the ones they hired. Because the answer differs by state and by project type, the contractor's own lien counsel should decide it rather than the contract manager.
What happens if the notice is late?
In most states a late notice does not simply reduce the claim; it destroys the lien right for the work performed before the notice period. Some states preserve rights for the work done in a window before service, which turns a late notice into a partial one. Either way, the deadline is unforgiving, and a claimant who missed it is left with an ordinary contract claim against whoever hired them.
