California Civil Code §8000 — The Mechanics Lien Law

California's comprehensive mechanics lien law, codified at Civil Code §8000 et seq., gives contractors, subcontractors, and suppliers a constitutional right to a lien on private construction projects to secure payment for their work and materials.

Constitutional Foundation

California's mechanics lien law has a constitutional basis — Article XIV, Section 3 of the California Constitution expressly provides for mechanics lien rights. This constitutional footing makes the lien right unusually strong and resistant to legislative erosion.

Who Has Lien Rights Under §8000 et seq.

Civil Code §8400 provides lien rights to any person who furnishes labor, service, equipment, or material for a work of improvement under a contract with the owner or the owner's agent — including the original contractor, subcontractors of any tier, material suppliers, equipment lessors, and design professionals.

The 2010 Revision

California's mechanics lien law was comprehensively reorganized in 2010 (effective 2011), consolidating and clarifying lien rights that had previously been scattered across the Civil Code and Code of Civil Procedure. The current statutory framework reflects this reorganization.

Lien Waivers Under §8120–8138

California strictly regulates the form of lien waivers. There are four statutory waiver forms: conditional waiver on progress payment, unconditional waiver on progress payment, conditional waiver on final payment, and unconditional waiver on final payment. Using non-statutory forms is risky — they may be unenforceable.
