Subcontractors: protect your payment rights with LienFlash. published: 2026-06-04T11:27:25.750Z updated: 2026-06-04T11:27:25.750Z canonical: https://lienflash.app/blog/mechanics-lien-california author: Grant Larsen publisher: LienFlash --- # California Mechanics Lien: Filing Requirements, Deadlines, and Process (2026) To enforce a mechanics lien in California, subcontractors and material suppliers on private works must first serve a 20-day preliminary notice under [Cal. Civ. Code § 8200](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8200.), then record a claim of mechanics lien with the county recorder within 90 days of the notice of completion or cessation — or within 60 days if a notice of completion was recorded — under [Cal. Civ. Code § 8412](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8412.) and § 8414. Subcontractors who skip the preliminary notice lose mechanics lien rights entirely on private works. After recording the lien, you must file a lawsuit to enforce it within 90 days or the lien expires automatically under [Cal. Civ. Code § 8460](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8460.). These are hard deadlines — there is no grace period and no cure once they pass. ## Who Is Required to File a California Preliminary Notice? Every subcontractor, material supplier, and equipment lessor on a California private works project must serve a 20-day preliminary notice to preserve lien rights — with one narrow exception. Under [Cal. Civ. Code § 8200](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8200.), direct contractors (those with a direct contract with the property owner) are not required to serve a preliminary notice, but every other tier must. That means if you're a sub, sub-sub, or supplier on a job, you must serve the notice regardless of how small the contract is or how well you know the GC. There is no dollar-amount threshold that exempts you. The rule applies equally to electricians, plumbers, roofers, HVAC contractors, drywall crews, painters, and any other trade working below the general contractor. On public works, the equivalent requirement is a 20-day preliminary notice to the public entity and the construction manager under [Cal. Civ. Code § 9300](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=9300.). Different rules apply to bond claims on public jobs — covered separately below. ## What Is the Deadline to Serve the 20-Day Preliminary Notice in California? The deadline is within 20 days of first furnishing labor, services, equipment, or materials on the project, per [Cal. Civ. Code § 8204](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8204.)(a). The clock starts on the first day you show up to do work or deliver materials — not when you signed the contract, not when the GC told you to mobilize. Serving late does not eliminate your lien rights entirely. Under [Cal. Civ. Code § 8204](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8204.)(b), a late-served notice protects only the work or materials furnished within the 20 days before service and everything furnished after. Everything before that 20-day window is unprotected. If you're 45 days into a job before you serve notice, the first 25 days of your work has no lien protection. The practical rule: serve the notice on day one. Many experienced subcontractors serve it before they step foot on the job — as soon as the contract is signed and they know the project address.

Code § 8200](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8200.), you must serve the 20-day preliminary notice on three parties: 1. **The property owner** (or reputed owner) 2. **The direct contractor** (your GC or prime contractor) 3. **The construction lender**, if any — and you must make a reasonable effort to identify whether one exists Failing to serve the construction lender does not void the notice entirely, but it does eliminate your priority position against lender-disbursed funds. On any project with a construction loan, this matters. Check the county recorder's office for a recorded deed of trust — that will typically identify the construction lender. Contact information for the owner and GC should appear in your contract. If the owner information is missing, check the recorded building permit or the county assessor's records. You are required to make a "reasonable effort" to obtain correct addresses — you cannot skip service simply because an address is difficult to locate. ## How Must the California Preliminary Notice Be Served? [Cal. Civ. Code § 8106](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8106.) specifies three acceptable service methods: - **Personal delivery** to the recipient - **First-class mail with a certificate of mailing** (proof of sending, not proof of receipt) - **Certified mail, return receipt requested** Certified mail is the industry standard because it creates the strongest proof chain. A certificate of mailing (available at any USPS counter) satisfies the statute but only proves you mailed something — it does not prove delivery. On any job where payment is even slightly uncertain, use certified mail. USPS Certified Mail costs $4.85 as the base service fee in 2026, plus standard First-Class postage. Adding electronic Return Receipt adds $2.46; a physical green card adds $4.10. For a $50,000 subcontract, that $7–9 in postage is one of the best investments you'll make. [California preliminary notice resources](/resources/california) ## What Must the California Preliminary Notice Include? Under [Cal. Civ. Code § 8102](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8102.), the notice must contain: - **A general description of the labor, services, equipment, or materials furnished** (or to be furnished) - **The name and address of the claimant** (your company) - **The name and address of the person who hired you** (your direct hiring party) - **The name and address of the owner or reputed owner** - **A description of the job site sufficient to identify it** (address or APN) - **The statutory warning language** required by [Cal. Civ. Code § 8202](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8202.) That statutory warning language is not optional boilerplate — it is legally required. [Cal. Civ. Code § 8202](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8202.) sets out the exact text in both English and Spanish that must appear on the notice. Using a form that omits this language or truncates it can invalidate your notice entirely. Attorney-reviewed templates that include the correct warning language are the only reliable way to ensure compliance. Using a random form pulled from the internet is a risk not worth taking on any job where you want to get paid. ## What Is the Deadline to Record a California Mechanics Lien? The mechanics lien recording deadline under [Cal. Civ. Code § 8412](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8412.) and § 8414 depends on whether a notice of completion or notice of cessation was recorded: | Scenario | Deadline to Record Lien | |---|---| | Owner records notice of completion | **60 days** after recordation | | Owner records notice of cessation | **60 days** after recordation | | No notice recorded | **90 days** after actual completion of the work | "Completion" under [Cal. Civ. Code § 8180](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8180.) means the earliest of: occupation or use of the work by the owner, cessation of labor for 60 consecutive days, acceptance of the work by the owner, or actual completion. Watch for any of these triggers — you cannot rely solely on whether the GC has called the job "done." The lien must be recorded at the county recorder's office in the county where the property is located. California does not accept liens filed in the wrong county — it must match the property's physical location. After recording, you must serve a copy of the lien on the property owner. Under [Cal. Civ. Code § 8416](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8416.)(a), service on the owner is required, though failure to serve does not invalidate the lien — it does, however, make the owner eligible to recover attorney's fees against you if you later fail to enforce. ## What Is the Deadline to Enforce (Foreclose) a California Mechanics Lien? You have 90 days from the date of recording the lien to file a lawsuit to enforce it, under [Cal. Civ. Code § 8460](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8460.). This deadline is absolute. If you do not file suit within 90 days, the lien expires by operation of law and cannot be revived. There is one narrow exception: if the owner records a "notice of credit" (an agreement giving the claimant additional time), the deadline can be extended up to one year from recording. But this requires the owner's cooperation — do not count on it. If you recorded the lien but the dispute is resolved before you sue, you must release the lien under [Cal. Civ. Code § 8480](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8480.). Failing to release a paid lien within 30 days of a written request exposes you to actual damages plus $3,000 statutory penalty plus attorney's fees under [Cal. Civ. Code § 8488](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8488.). According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days. In California, the mechanics lien is the primary legal tool that gives subcontractors leverage to actually collect. ## How Do California Mechanics Liens Work on Public Projects? On California public works, mechanics liens do not attach to public property. Instead, subcontractors and suppliers have rights against the payment bond under the Public Works Payment Bond statutes, [Cal. Civ. Code § 9550](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=9550.) et seq. To preserve bond claim rights, you must serve a 20-day preliminary notice on the public entity and the original contractor under [Cal. Civ. Code § 9300](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=9300.). The deadline structure mirrors private works — within 20 days of first furnishing, and late service cuts off protection for earlier work. After serving notice, the deadline to make a bond claim is **6 months after the period for recording a mechanics lien would have expired** on an equivalent private works project, under [Cal. Civ. Code § 9558](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=9558.). This is a longer window than private works enforcement, but the preliminary notice requirement is just as strict. ## How Much Does It Cost to File a California Mechanics Lien? County recorder filing fees in California vary by county but typically run $15–$25 for the first page and $3 per additional page. Los Angeles County, San Diego County, and other large counties publish their current fee schedules on their recorder websites. The bigger cost consideration is what you lose if you skip the process. According to the Rabbet 2024 Construction Payments Report, slow payments cost the U.S. construction industry an estimated $280 billion in 2024, adding roughly 14% to total construction spending. A mechanics lien — properly filed — is the single most effective tool a California subcontractor has to get paid without hiring a collection attorney. A single LienFlash preliminary notice is $24.99 and includes an attorney-reviewed California-compliant form plus USPS Certified Mail with return receipt. If it protects a $15,000 subcontract that would otherwise go unpaid, the return on that $24.99 exceeds 60,000%. [lien deadline calculator](/tools/lien-deadline-calculator) ## Frequently Asked Questions ### Does a California subcontractor have to file a preliminary notice on every job? Yes. Every subcontractor, material supplier, and equipment lessor on a California private works project must serve a 20-day preliminary notice to preserve mechanics lien rights, under [Cal. Civ. Code § 8200](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8200.). There is no dollar threshold, no exemption for small jobs, and no exemption based on your relationship with the GC or owner. Skipping it on any job means you have zero lien rights on that job. ### What happens if I missed the 20-day deadline to serve the California preliminary notice? Serve it immediately anyway. Under [Cal. Civ. Code § 8204](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8204.)(b), a late-served preliminary notice still protects work performed within the 20 days before service and all work performed after service. You lose lien rights on everything before that window, but you preserve rights on the remaining work. Do not wait any longer than necessary. ### Can I serve the California preliminary notice before I start work? Yes, and it is a common practice. [Cal. Civ. Code § 8204](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8204.) allows service before first furnishing. Serving the notice before mobilization — or the day your contract is signed — ensures maximum protection from day one and eliminates any risk of a missed deadline. ### Does California require me to notify the construction lender? Yes. Under [Cal. Civ. Code § 8200](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8200.)(b), the preliminary notice must also be served on the construction lender, if any. You must make a reasonable effort to identify whether a construction loan exists. Check the county recorder for a recorded deed of trust tied to the property. Failing to serve the lender does not void your lien against the owner, but it eliminates your priority against lender-disbursed funds. ### How do I find out if a notice of completion was recorded so I can calculate my lien deadline? Check the county recorder's office in the county where the project is located. Notices of completion are recorded documents and are publicly searchable. Many county recorders have online search tools. The recording date is what triggers your 60-day lien deadline under [Cal. Civ. Code § 8412](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8412.) — not the date you learned about it. ### Can a property owner force me to release a California mechanics lien? Yes. Under [Cal. Civ. Code § 8424](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8424.), an owner can petition the court to release a lien if you fail to file a lawsuit to enforce within 90 days of recording. The owner can also demand a release in writing after the debt is paid — you must release within 30 days of a written demand under [Cal. Civ. Code § 8486](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8486.), or you face statutory penalties. ### What is the difference between a mechanics lien and a stop payment notice in California? A mechanics lien ([Cal. Civ. Code § 8400](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8400.) et seq.) attaches to the real property itself and is enforced by foreclosure. A stop payment notice ([Cal. Civ. Code § 8500](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=CIV§ionNum=8500.) et seq.) is directed at the construction lender or owner, requiring them to withhold funds from the GC until your claim is resolved. You can file both on the same project. A stop payment notice is often faster and more practical when the job is still in progress and construction funds are still being disbursed. ### Does a mechanics lien affect the property owner's ability to sell or refinance the property? Yes. A recorded mechanics lien is a cloud on title. Title companies will not insure a sale or refinance without the lien being released or bonded off. This is the core leverage that makes California mechanics liens effective — the owner has a direct financial incentive to resolve your payment dispute to clear title. ## Protect Your Lien Rights Today California's lien law is strict, deadline-driven, and unforgiving.
