California Lien Waivers & Pay-App Requirements for Commercial Subcontractors

California has the strictest statutory lien waiver requirements in the United States. Commercial subcontractors billing on California jobs must use the four statutory waiver forms in California Civil Code §§8132, 8134, 8136, and 8138 — and deviations from the statutory language invalidate the waiver under California law.

This page covers the four waiver types California recognizes, the specific form language, the down-to date and signer rules, DIR public-works compliance, retainage law, lien deadlines, and the most common reasons California waiver submissions get rejected or held legally inadequate.

Statute & form reference

California's mechanics-lien chapter (Civil Code Title 2.5) was overhauled in 2012, replacing the prior "Civil Code §3262" series with the current §8132/8134/8136/8138 statutory forms. Most California GCs and owners updated their subcontract templates to reference the new sections shortly after; some legacy subcontracts still cite §3262 by mistake.

The four statutory waiver forms are:

• CA Civ. Code §8132 — Conditional Waiver and Release on

Progress Payment.

• CA Civ. Code §8134 — Unconditional Waiver and Release on

Progress Payment.

• CA Civ. Code §8136 — Conditional Waiver and Release on

Final Payment.

• CA Civ. Code §8138 — Unconditional Waiver and Release on

Final Payment.

The statutory language for each form must be reproduced substantially verbatim. Boilerplate or "good enough" paraphrases get challenged.

The four waiver types

Conditional Waiver on Progress Payment (§8132)

Most-used waiver type on commercial work. Releases lien rights for the labor and materials covered by a specific progress payment, conditioned on the check actually clearing.

Used for:

• Every monthly pay app on commercial subcontracts.
• Submitted with the AIA G702/G703 packet to the GC.

Risk: low. The conditional language protects the sub if the payment fails to clear.

Unconditional Waiver on Progress Payment (§8134)

Releases lien rights for the labor and materials covered by a specific progress payment, absolutely, without payment condition.

Used for:

• Confirming a prior period's payment has cleared.
• Some GCs require this on the next-cycle packet to confirm last

period's payment.

Risk: high. Never sign before the check has cleared. Once signed, the lien rights for that period are gone whether or not the payment ultimately funds.

Conditional Waiver on Final Payment (§8136)

Final-payment version of §8132. Releases lien rights for all work performed under the subcontract, conditioned on final payment clearing.

Unconditional Waiver on Final Payment (§8138)

Final-payment version of §8134. Releases lien rights for all work performed under the subcontract, absolutely.

Risk: high. Sign only after the final check has cleared and any retainage release has hit your account.

Down-to date requirements

Every California waiver must include a "through" date — the date through which the waiver releases lien rights. Typical practice:

• Conditional progress: through the **end of the current pay

period**.

• Unconditional progress: through the **end of the prior pay

period** (the one being confirmed paid).

Missing or incorrect through dates are one of the top three California waiver rejection causes. The waiver is technically invalid without a through date, even if the rest of the form is perfect.

Signer authority

California Civil Code §8132(b) requires waivers signed by someone with authority to release lien rights on behalf of the claimant. In practice this means:

• Corporate officer of the subcontractor entity.
• Designated signer with documented authority (typically per

corporate resolution).

Estimator and project manager titles do not have inherent authority under §8132(b). Some GCs (Skanska, Turner) reinforce this with subcontract Exhibit C authorized-signer rosters.

Lower-tier waiver rules

California requires waivers from sub-tier vendors as a condition of the prime sub's payment, where the prime sub is billing for materials or labor furnished through that vendor. Most commercial GCs in California require:

• Waivers from any vendor billed >$500 in the period.
• Waivers from any second-tier sub regardless of dollar value.
• Material supplier waivers for any stored-materials line.

Chasing lower-tier waivers is the most-hated admin task in California construction AR. SubCash automates the chase.

Public works — DIR eCPR compliance

California public-works projects require weekly Certified Payroll Reports uploaded to the DIR eCPR portal. The DIR (Department of Industrial Relations) auto-blocks the awarding body from approving the next pay app on missing or rejected weekly CPRs.

Subs working California public works (state, county, city, or any project funded with public money) must:

• Register with the DIR.
• Upload weekly CPRs in DIR's XML format.
• Maintain apprentice ratios per the DIR's apprenticeship

regulations.

Missing weekly DIR uploads block your next pay app at the awarding-body level — not at the GC. The GC will not chase you; they'll simply not approve your next billing.

Retainage law

California Public Contract Code §7107 caps retainage on public works at 5%. Private commercial work has no statutory cap and typically runs 10% (often switching to 5% at 50% complete).

Retainage release on California public work is governed by §7107: 60 days from substantial completion for the public-works prime contract; downstream subs generally get released through the GC's retainage pass-through.

Lien deadlines (don't miss these)

• Preliminary notice (20-day notice): must be served within

20 days of first furnishing labor or materials. CA Civil Code §8200. Without preliminary notice, lien rights are generally lost.

• Mechanic's lien recording: within 90 days of completion

of the work of improvement, or 60 days after notice of completion is recorded by the owner. CA Civil Code §8412/8414.

• Suit on lien: within 90 days of lien recording. CA

Civil Code §8460.

These are bright-line deadlines. SubCash's OS subscription tracks them per project and alerts at 30/14/7 days before each deadline.

FAQ

Q: Does California require a specific lien waiver form? A: Yes. California Civil Code §§8132, 8134, 8136, and 8138 provide statutory waiver forms that must be used. Deviations from the statutory language invalidate the waiver. Most GCs require the §8132 form for every monthly progress payment.

Q: What's the down-to date requirement on a California waiver? A: Every California waiver must include a "through" date — the date through which the waiver releases lien rights. Typical practice: through the end of the current pay period for conditional progress waivers, through the end of the prior pay period for unconditional progress waivers.

Q: Can a subcontractor waive lien rights before payment clears in California? A: Yes — that's exactly what an Unconditional Waiver on Progress Payment (§8134) does. Don't sign one before the check has cleared. Once signed, the lien rights for that period are gone whether or not the payment ultimately funds.

Q: What's California's retainage max on public works? A: 5% under California Public Contract Code §7107. Private commercial work has no statutory cap and typically runs 10% (often switching to 5% at 50% complete).

Q: How long does a California sub have to file a mechanic's lien? A: 90 days from completion of the work of improvement, or 60 days after the owner records a notice of completion. CA Civil Code §8412/8414. The deadline is bright-line; missing it loses the lien remedy.
