Mechanics Liens and Lien Releases, Explained for Homeowners

A letter shows up from a lumber yard or a plumbing company you have never spoken to, addressed to you. Nothing has gone wrong. You are almost certainly holding a preliminary notice.

Keep it, add the sender to a running list, and make sure that company signs a release covering their work as your payments go out.

Why a company you never hired can send you notice

Your contract is with the general contractor. Most of the labor and nearly all of the material comes from elsewhere. The framing crew, the electrical sub, the yard that delivered your windows, none of them signed anything with you.

California law still gives those parties a route to payment. A subcontractor, supplier, or laborer who improves your property and does not get paid can record a mechanics lien against that property, even when you paid your contractor in full and on time. Sending a preliminary notice early in the job is how most of them preserve that right, and those deadlines are strict. That is why it arrives long before anyone is owed money.

A preliminary notice is not a lien. It is not a bill, and not a complaint about you or your contractor. Treat it as a name for your list.

The situation this system exists to prevent

You pay your contractor for the tile. The contractor, for whatever reason, does not pay the tile supplier. That supplier records a lien against your home, which clouds your title and surfaces the next time you refinance or sell. Clearing it can mean paying for the same tile twice.

This is not the normal course of a project, and where it does happen it more often involves a contractor in financial trouble than bad faith. Your house is the collateral either way.

What a lien release actually is

A lien release, also called a waiver and release, is a signed document in which someone who could lien your property gives up that right for work through a stated date and amount. California prescribes four statutory forms, and the differences matter.

Conditional waiver and release on progress payment. Takes effect only if the payment actually clears. Exchange it when you hand over a draw.
Unconditional waiver and release on progress payment. The statutory form that takes effect on signature rather than on payment, which is why owners are generally advised to hand one over only after the payment has cleared. Have your attorney confirm how each form applies before you sign or accept one.
Conditional waiver and release on final payment. Same logic as the conditional progress form, applied to the last payment.
Unconditional waiver and release on final payment. The document that closes the job out.

The language is prescribed, so be skeptical of a release someone typed up themselves. Have your attorney check any unfamiliar form before you trade money for it.

How to run this on a real project

Ask your contractor for a list of subcontractors and material suppliers before work begins, and for updates as new ones come on.
Keep every preliminary notice in one folder. That folder is your checklist.
Put the requirement in the contract. Each payment goes out against releases from the contractor and from anyone on your list whose work that payment covers.
Trade the check for conditional releases, then circle back for the unconditional versions after it clears.
Many owners hold final payment until unconditional final releases are in hand from everyone who sent notice. Ask a construction attorney how that should be written into your contract.

A joint check naming both the contractor and a supplier you are unsure about is another option.

Where this goes wrong

Notices get thrown out because they look like junk mail, so the list never exists.
Releases are collected from the general contractor only. That signature does not speak for the subs.
Conditional releases pile up and the unconditional versions never get collected, leaving gaps.
Amounts and through dates are left blank or do not match the payment, so a release covers less than assumed.
Change order work performed after a through date is not covered by a release signed earlier.

If a lien is recorded anyway

Do not wait it out. Tell your contractor in writing the day you learn of it, and ask your attorney what your contract requires them to do about it. A lien has to be enforced within a window set by statute or it becomes removable, but those rules are specific and the procedure is not worth guessing at. Call a California construction attorney promptly. Deadlines run whether or not anyone tells you they started.

What to ask before you sign

Ask any contractor how they handle preliminary notices and releases, and whether they will provide unconditional releases with each draw. The answer tells you how carefully they run their books. We expect the question, and our license number is 1063782 if you want to check it at cslb.ca.gov.

This describes the general framework, not your situation, and it is not legal advice. California mechanics lien law is technical. Take your project to a construction attorney.
