A notice that comes first
The California preliminary notice is defined by its position. Civil Code §8200(a) places it before three remedies:
Except as otherwise provided by statute, before recording a lien claim, giving a stop payment notice, or asserting a claim against a payment bond, a claimant shall give preliminary notice to the following persons:
It is preliminary in the plain sense: it precedes. The three things it precedes are the mechanics lien, the stop payment notice and the claim on a payment bond. None of them is the notice, and the notice is none of them. What the notice does is put three parties on record as having been told, early, that a particular claimant is furnishing work to the project.
Who gives it, and to whom
The same subsection names the recipients:
(1) The owner or reputed owner. (2) The direct contractor or reputed direct contractor to which the claimant provides work, either directly or through one or more subcontractors. (3) The construction lender or reputed construction lender, if any.
The giver is the claimant, the statute's word for the party furnishing work who may later need one of the three remedies. The receivers are the owner, the direct contractor and the lender when there is one. Each is paired with its reputed counterpart, and the contents section asks for their names and addresses to the extent known to the person giving the notice, which is how the statute handles a job where the claimant has never met the owner. The recipients page takes the three apart one at a time.
Two parties are treated differently:
(1) A laborer is not required to give preliminary notice. (2) A claimant with a direct contractual relationship with an owner or reputed owner is required to give preliminary notice only to the construction lender or reputed construction lender, if any.
That is §8200(e). A laborer is excused. A claimant who contracted with the owner directly still gives the notice, but only to the lender, and only if there is one.
Why it is not optional
Compliance with this section is a necessary prerequisite to the validity of a lien claim or stop payment notice under this title.
Compliance with this section or with Section 8612 is a necessary prerequisite to the validity of a claim against a payment bond under this title.
Subdivisions (c) and (d) of §8200 are the reason the notice exists as a business practice rather than a courtesy. The lien and the stop payment notice depend on it. The payment bond claim depends on it or on the alternative the statute names in §8612, which is not quoted here. A claimant who skipped the notice and later needs a lien has a problem the lien paperwork does not supply an answer to; a claimant who gave it has passed the gate.
What it says to the owner
The notice is not a blank form with names on it. Section 8202(a)(3) requires a statement, in boldface type, and dictates its words. The first paragraph is the one that explains the whole device:
EVEN THOUGH YOU HAVE PAID YOUR CONTRACTOR IN FULL, if the person or firm that has given you this notice is not paid in full for labor, service, equipment, or material provided or to be provided to your construction project, a lien may be placed on your property. Foreclosure of the lien may lead to loss of all or part of your property. You may wish to protect yourself against this by (1) requiring your contractor to provide a signed release by the person or firm that has given you this notice before making payment to your contractor, or (2) any other method that is appropriate under the circumstances.
Read from the owner's chair, the notice is a warning and a suggestion: a lien may follow non-payment down the chain, and a signed release before each payment is one way to prevent it. Read from the claimant's chair, it is the reason the owner will know your name before any dispute begins. The form page quotes the statement in full, with the other lines §8102 and §8202 require.
When it is given
A preliminary notice shall be given not later than 20 days after the claimant has first furnished work on the work of improvement.
Twenty days from first furnishing, under §8204(a). The same subsection goes on to say that a claimant who missed the window shall not be precluded from giving a preliminary notice at any time thereafter, with the remedies reaching back 20 days from service. That is a page of its own: what happens after 20 days.
What it is not
Three negatives, each from the statute rather than from us.
It is not a lien. Section 8200(a) places it before recording a lien claim; it is the step that precedes the lien, not the lien.
It is not a demand for payment. The line §8102(a)(6)(C) asks for is a statement or estimate of the claimant's demand, if any, after deducting all just credits and offsets. An estimate of what may be owed is information the notice carries; it is not a stop payment notice and it is not a bill.
It is not a comment on the contractor. The statutory statement says so in its own text:
This notice is not intended to reflect upon the financial condition of the contractor or the person employed by you on the construction project.
The owner is told, in the notice itself, that receiving it says nothing about whether the contractor is solvent or honest. It is a routine document on a compliant job.
What happens after it
Usually nothing, which is the point. The claimant is paid, the job ends, and the notice sits in three files. When payment fails, the three remedies §8200(a) names become available for the work the notice covers, each under rules of its own that this page does not quote. The Notice of Intent to Lien is a separate document, often sent before recording a lien, and is not a substitute for the preliminary notice.
Giving one
The notice is three envelopes, the required lines, the boldface statement and a method of service the statute allows. NoticeSent fills it from your answers, certified-mails each recipient with tracking, and keeps the document and the deposit record on a permanent archive page for one flat $39. How to send it walks through §8106, §8110 and §8116.
Frequently asked
Is a California preliminary notice a lien?
No. The statute treats the preliminary notice as a step that comes before recording a lien claim, giving a stop payment notice or asserting a claim against a payment bond (§8200(a)), and §8200(c) calls compliance a necessary prerequisite to the validity of a lien claim or stop payment notice. The notice itself records nothing against the property.
Does giving a preliminary notice mean the contractor is in trouble?
The statutory statement the notice carries answers that directly: it is not intended to reflect upon the financial condition of the contractor or the person employed by you on the construction project (§8202(a)(3)). The notice is required by law and describes the owner's rights; it is not an accusation.
Who does not have to give one?
Section 8200(e) names two cases: a laborer is not required to give preliminary notice, and a claimant with a direct contractual relationship with the owner is required to give it only to the construction lender, if any. Whether either describes you is a legal question this page cannot answer.
