What is a preliminary notice in construction?

A preliminary notice is a written notice sent early in a project by a subcontractor, supplier, or other party, telling the owner and others that it is providing work and has lien and bond claim rights.

A preliminary notice (often called a "prelim") is the paperwork that keeps lien rights alive. Many states require it from subcontractors and suppliers before they can record a mechanics lien, file a stop payment notice, or claim against a payment bond. It is not a complaint and it does not mean anyone is behind on payment. It is a routine disclosure, like a certificate of insurance.

States use different names. Florida calls its version a notice to owner. Others say notice of furnishing or pre-lien notice. California uses "preliminary notice," so its rules are used as the example here.

California's 20-day rule

Under California Civil Code 8204, a preliminary notice must be given no later than 20 days after the claimant first furnishes work on the project. A late notice is still worth sending, but it only protects work performed within 20 days before it was served and everything after. Design professionals have a slightly different rule tied to when the work of improvement commences.

How a late California preliminary notice cuts coverage (example)
ItemDate or amount
Electrical sub starts workMarch 1
Deadline for full coverageMarch 21
Notice actually servedApril 30
Work protected by lien and bond rightsWork from April 10 forward
Work from March 1 to April 9Not protected

In this example, if the sub had $70,000 of work in place by April 9, that amount is outside its lien and bond rights. Twenty minutes of paperwork in March would have covered it.

How it works on a real job

A well-run sub treats the prelim as part of signing a new job. The office collects the owner's legal name, the property address and description, the GC, the lender, and any surety from the contract or the GC's information sheet. It sends the notice by a method that proves delivery and saves the proof. Suppliers do the same thing for every customer account tied to a jobsite.

Owners and GCs use the notices too. A stack of prelims tells the GC who is actually on the job, including sub-tiers it may not know about. That list is the starting point for collecting conditional lien waivers with each pay application.

Common mistakes

  • Sending it only when payment slows down. By then the coverage window may have closed.
  • Thinking a direct contract with the owner always exempts you. Rules differ by state and by claimant type, so check yours.
  • Bad property description. Use the description in the contract or county records, not the marketing name of the project.
  • No proof of delivery. If you cannot prove service, assume you will have to argue about it.
  • Missing public jobs. On public work, liens usually do not attach to public property, but notice rules for bond and stop payment claims can still apply.

The preliminary notice is the first step in the lien process, followed by lien waivers on each payment and, if needed, a notice of intent to lien. On the back end, a recorded notice of completion can shorten lien deadlines. For a how-to, see how to send a preliminary notice.

Frequently asked questions

Who needs to send a preliminary notice?

It depends on the state. Subcontractors, sub-subcontractors, suppliers, and equipment lessors are the usual senders. Some states also require it from certain direct contractors or on certain project types.

What is the California preliminary notice deadline?

No later than 20 days after first furnishing work. A late notice protects only work performed within 20 days before service and after.

Does sending a preliminary notice upset the general contractor?

On most commercial jobs it is routine and expected. Explaining that it is standard practice for every job usually settles any concern.

Is a preliminary notice required on public jobs?

Often yes, for bond and stop payment claims, even though mechanics liens usually cannot attach to public property. Check your state's public works rules.
