SB 33 sets a state-law process to force quicker resolution of contractor claims on public works projects and to ensure undisputed portions get paid promptly. The statute creates a sequence of required steps — a written response from the public entity, a meet-and-confer window, nonbinding mediation for disputes, and an interest remedy for late payment — and permits contractors to present claims on behalf of subcontractors who lack privity.
The bill matters because it replaces ad hoc, contract-by-contract approaches with a uniform claim-resolution timetable for most public owners in California. For contractors and subcontractors that regularly chase payments on public projects, SB 33 promises clearer timelines and an enforceable path to recover undisputed sums; for public entities it creates new administrative deadlines, potential interest exposure, and fresh procedural obligations to insert into contract documents.
At a Glance
What It Does
SB 33 requires a public entity to review a contractor claim and, within 45 days, identify disputed and undisputed portions; undisputed portions must be paid within 60 days of that written statement. If the parties remain at odds, the statute mandates a meet-and-confer within 30 days and nonbinding mediation with costs split equally; failure by the public entity to meet timing requirements results in the claim being deemed rejected.
Who It Affects
Direct contractors on public works projects and their subcontractors, local and many state public entities (with specified state department exceptions), construction contract administrators, and ADR providers who will handle the required nonbinding mediation. The statute explicitly allows prime contractors to present claims on behalf of subcontractors that lack privity.
Why It Matters
The bill standardizes pre-litigation procedures and creates concrete payment timing and a 7% interest remedy for late payments, shifting risk and administrative burdens toward public owners and changing how contractors manage cash flow and dispute strategy. It also carves out several major state agencies and includes a sunset date, producing a non-uniform landscape that will affect large projects and smaller local work differently.

What This Bill Actually Does
SB 33 creates a step-by-step claim resolution process for contractors on most California public works projects. A contractor must send a claim by registered or certified mail; the public entity must then perform a reasonable review and issue a written statement within 45 days identifying which parts it disputes and which it accepts as undisputed.
The contractor must support the claim with reasonable documentation; the public entity may extend the 45-day review by mutual agreement or, where a governing body approval is required and no meeting occurs in the 45‑day window, it gets up to three days after the next publicly noticed meeting to issue its statement.
When the public entity identifies undisputed amounts, those sums must be processed and paid within 60 days of the written statement. If the public entity fails to provide the required written response within the timeframes, the statute treats the claim as rejected in its entirety — a procedural consequence that the bill says does not reflect the merits of the claim or the claimant’s qualifications.
If the contractor disputes the entity’s response (or lack of response), the contractor may demand an informal meet-and-confer; the entity must schedule that meeting within 30 days.If disputes remain after the meet-and-confer, the unresolved portions are sent to nonbinding mediation (which the statute defines broadly to include neutral evaluation or dispute review boards). The parties split mediation costs equally and must either mutually choose a mediator within 10 business days or follow the two-mediator selection method the statute prescribes (each party selects a mediator and those mediators then pick a neutral).
Mediation under SB 33 is nonbinding and substitutes for any mediation obligation under Section 20104.4 unless the parties waive it in writing and proceed directly to litigation or binding arbitration.The statute adds two practical procedural rules: a contractor may present a subcontractor’s claim to the public entity where the subcontractor lacks privity, and plans or specifications for a public works project must include the text or a summary of this section. It also forbids contractual waivers of the statute’s rights (except by mutual written agreement to skip mediation) and allows public entities to adopt additional, reasonable change-order or claim procedures so long as they do not conflict with the statute’s timeframes.SB 33 lists several state agencies as exclusions (including the Departments of Water Resources, Transportation, Parks and Recreation, Corrections and Rehabilitation for certain projects, the Military Department, the Department of General Services for other projects, and the High-Speed Rail Authority).
The section applies to contracts entered into on or after January 1, 2017, and contains a sunset clause that repeals it on January 1, 2027 unless extended by later statute.
The Five Things You Need to Know
A public entity must issue a written statement within 45 days of receiving a contractor’s claim identifying disputed and undisputed portions (extensions allowed by mutual agreement or limited governing-body exception).
Undisputed portions must be processed and paid within 60 days after the public entity issues its written statement.
If the public entity fails to meet the statute’s timing requirements, the claim is deemed rejected in its entirety — a procedural conclusion that the statute says is not an adverse finding on the merits.
Disputed portions are subject to nonbinding mediation with mediation costs split equally and a 10-business-day deadline to agree on a mediator (backstop selection procedure if parties cannot agree).
Amounts not paid timely under the statute bear interest at 7 percent per annum; major state agencies (DWR, Caltrans, Parks, CDCR for certain projects, Military Department, DGS for other projects, and the High-Speed Rail Authority) are expressly excluded.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Legislative findings and purpose
This short subsection explains the statute’s objective: to ensure complete and timely payment for finished, undisputed construction work on public projects. Its practical function is to frame all subsequent rules as safeguards aimed at payment certainty rather than tools for changing substantive contract rights.
Scope and key definitions (what counts as a claim, who is a contractor, which public entities are covered)
Subdivision (b) declares that this new section applies to contractor claims notwithstanding several existing public contract provisions. Subdivision (c) defines 'claim' narrowly as a registered- or certified-mail demand for time extension, payment or disputed payment, and defines 'contractor,' 'subcontractor,' 'public works project,' and 'public entity.' Practically, the definitions set the statute’s perimeter: it covers traditional licensed contractors and projects that fit the classic public-works mold, while carving out several large state agencies and certain classes of projects from coverage.
45-day review, documentation requirement, and governing-body timing exception
Upon receipt of a compliant claim, the public entity must conduct a reasonable review and provide a written statement within 45 days identifying disputed versus undisputed amounts; the claimant must supply reasonable documentation to support the claim. If a governing-body approval is needed but the governing body does not meet within the 45 days (or mutually agreed extension), the public entity gets up to three days after the next duly noticed meeting to issue its statement. This creates a tight administrative deadline and a narrowly drawn exception for approval-cycle realities.
Meet-and-confer, mediation mechanics, and deemed-rejection consequence
If the claimant disputes the entity’s written response or the entity fails to respond, the claimant can demand an informal meet-and-confer to be scheduled within 30 days. If dispute persists, the statute requires nonbinding mediation for the disputed portions, with equal cost-sharing and a ten-business-day window to pick a mediator (or a two-mediator backstop selection). If the public entity fails to meet the timing obligations in this subdivision, the claim is deemed rejected — a procedural trigger that preserves the claimant’s next-step rights but is defined to avoid implying merit-based disfavor.
Payment timing for undisputed amounts, interest, and subcontractor representation
Any undisputed portion must be processed and paid within 60 days after the public entity’s written statement; amounts unpaid under the statute bear 7 percent annual interest. For subcontractors without privity to sue the public entity, the prime contractor may present a claim on their behalf; subcontractors may ask a prime to present such claims and the prime must notify the subcontractor within 45 days whether it did so and why not if it declined. These provisions create direct cash-flow protections and an administrative duty on primes to respond to subcontractor requests.
Contract document disclosure and limits on waiver
The statute requires that its text or a summary be included in project plans or specifications, making the procedure a contract-level notice. It also declares general contractual waivers void while preserving a narrow option for mutual written waiver to skip mediation and proceed immediately to litigation or binding arbitration; public entities may add reasonable procedures provided they do not conflict with the statute’s timeframes. Practitioners should expect standard form contract language updates and careful drafting to avoid conflicts.
Effective date, grants/loans carveout, and sunset
The section applies to contracts entered into on or after January 1, 2017. It does not impose liability on public entities that only provide competitive loans or grants for awardees’ contractual failures. Finally, the statute contains a sunset clause that repeals it on January 1, 2027 unless extended — a built-in trial period that affects how stakeholders will value and respond to the rules.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Direct contractors on covered public works projects — gain a predictable pre-litigation process, a binding timeline for the public entity’s written response, and a faster route to payment for undisputed work, improving cash-flow planning.
- Subcontractors and lower-tier subcontractors — receive an explicit avenue to have claims presented on their behalf by prime contractors when they lack privity, plus an obligation for the prime to reply within 45 days about whether it presented the claim.
- ADR providers and mediators — will see increased demand because the statute mandates nonbinding mediation and prescribes quick mediator-selection timelines, creating steady work for qualified neutrals.
Who Bears the Cost
- Public entities (local governments and many state agencies) — must staff faster claim reviews, process timely payments (including interest exposure at 7%), schedule meet-and-confers and mediations on short notice, and potentially revise contract forms and procurement procedures.
- Prime contractors — although beneficiaries, they also bear administrative burdens in assembling documentation, managing meet-and-confer and mediation logistics, and acting on subcontractor requests to present claims (with a 45-day notification duty if they decline).
- Project owners’ legal and contracting offices — will incur costs revising procurement manuals, training personnel on new timelines and the governing-body exception, and handling an uptick in pre-litigation ADR under the statute.
Key Issues
The Core Tension
The central tension is between enforcing fast payments to protect contractors’ cash flow and preserving public entities’ duty to rigorously investigate and withhold disputed sums; speeding resolution reduces administrative friction and financing risk for contractors but risks premature payouts or strained oversight for public owners — a trade-off that the statute addresses with strict timelines, limited exceptions, and a temporary sunset rather than a permanent, full-scale reallocation of risk.
SB 33 swaps varied contract language for a uniform set of deadlines and ADR steps, but that shift introduces classic trade-offs. Speed and predictability for contractors come at the cost of compressing public entities’ review windows; entities with complex approval chains may struggle to meet the 45- and 60-day clocks without reallocating staff or invoking the narrow governing-body exception.
The statute’s deemed-rejection rule is procedural — it preserves the contractor’s ability to proceed — but it does not answer how courts will treat claims that are commercially disputed yet procedurally 'rejected,' or how it interacts with other statutory or contractual withholding rights tied to defects, public-safety holds, or retainage.
The bill also creates a patchwork: several major state project owners are excluded, and the statute itself sunsets in 2027. That means contractors and owners will face asymmetric rules depending on the client and a built-in period for reassessment — a dynamic that could complicate bidding, bonding, and risk allocation on multi-owner or programmatic projects.
Additional open questions include the statute’s interplay with attorneys’ fees provisions, how interest accrual is to be calculated operationally for partial payments, and whether short mediator-selection windows will produce rushed or procedurally flawed ADR that fails to settle disputes but consumes resources.
