What Is SB 440

The Private Works Change Order Fair Payment Act

Signed into law by Governor Newsom in October 2025 and effective January 1, 2026, SB 440 fundamentally changes how change orders and claims are handled on private construction projects in California — bringing private projects under the same structured claims process that public agencies have navigated for years.

Before SB 440, California had no specific statutory process for resolving change order claims on private works. Owners and contractors were left to negotiate — or litigate — without a consistent legal framework. That lack of structure often favored whoever had more resources and patience. SB 440 changes that balance permanently.

"SB 440 marks a turning point in California private construction. A faster, fairer process that rewards responsiveness — and punishes owners who aren't prepared."

The law applies to all private construction contracts entered into on or after January 1, 2026. It will remain in effect through January 1, 2030 unless extended by the legislature. With penalties of up to 24% annual interest and contractor stop-work rights, the cost of being unprepared is significant.

Key Provisions & Deadlines

SB 440 takes effect. All new private construction contracts are subject to the new claims process.

60 Days
Claim submission window. Contractors must submit claims within 60 days of discovery via certified mail.
30 Days
Owner response required. Owners must respond in writing identifying disputed vs. undisputed amounts.
60 Days
Undisputed payment due. Owners must pay undisputed amounts or face 2% monthly interest penalties.

What's at Risk

What Unprepared Owners Face Under SB 440

01
Interest Penalties Up to 24%
If you fail to pay undisputed change order amounts within 60 days, interest accrues at 2% per month — 24% annually. On a $500K disputed change order, that's $10,000 per month in penalties while you're still in dispute.
Financial Exposure
02
Contractor Stop-Work Rights
For the first time in California private construction, GCs have a legal right to stop work if owners don't respond properly to claims. A stopped project costs far more than the original dispute — escalating costs, delays, and potential financing defaults.
Project Disruption
03
30-Day Response Window
When a contractor submits a claim, you have just 30 days to respond in writing with a detailed analysis of disputed and undisputed portions. Without a CPM scheduler and claims expert on your side, meeting that deadline with a defensible response is nearly impossible.
Tight Deadlines
04
No Documentation = No Defense
SB 440 claims hinge on contemporaneous documentation — daily logs, schedule updates, RFI responses, and change order records. Owners who haven't maintained proper CPM scheduling from Day 1 have no factual basis to dispute a contractor's claim.
Evidence Gap
05
Contract Non-Compliance
All private contracts entered into after January 1, 2026 must be updated to reflect SB 440's requirements. Contracts that don't properly incorporate the new claim timelines and procedures may expose owners to additional legal vulnerability.
Legal Exposure
06
Subcontractor Flow-Down Risk
SB 440 requirements must flow down through the contract chain. If your GC's subcontracts don't properly incorporate SB 440 procedures, subcontractor claims may jeopardize the GC's ability to pass claims through — leaving you exposed to direct subcontractor action.

The SB 440 Claims Process

How a Claim Unfolds — And Where BCI Protects You

Under SB 440, every change order dispute follows a defined process. Here's what happens — and exactly where BCI's expertise protects your interests at each step.

Day
1
Project Start — Documentation Begins
The moment your contract is signed, the SB 440 clock starts. Every schedule update, RFI, change order request, and site condition must be documented contemporaneously. This is your evidence base for every future dispute.
BCI: CPM baseline schedule, documentation protocols, contract review
Event
Occurs
Change Order or Delay Event
A differing site condition, owner-directed change, or delay event occurs. The contractor has 60 days from discovery to submit a formal written claim via certified mail. Your documentation from Day 1 is now critical.
BCI: Schedule impact analysis, change order evaluation, cost review
+60
Days
Contractor Submits Formal Claim
The GC submits a written claim by certified mail demanding time extension relief, additional compensation, or both. The 30-day owner response window begins immediately upon receipt.
BCI: Claim receipt tracking, forensic schedule review begins
+30
Days
Owner Must Respond in Writing
You have 30 days to respond in writing identifying which portions of the claim are disputed and undisputed. Failure to respond constitutes a denial — but still triggers interest penalties on any amounts later found to be undisputed.
BCI: Written response preparation, forensic delay analysis, claim evaluation
+60
Days
Undisputed Amounts Must Be Paid
Any undisputed amounts must be paid within 60 days of the claim. Failure to pay triggers 2% monthly interest. Continued non-payment gives the contractor legal stop-work rights.
BCI: Payment tracking, dispute documentation, stop-work prevention strategy
Meet
&
Confer
Dispute Resolution Process
For disputed amounts, the contractor can request a meet-and-confer. The owner must schedule within 30 days. If unresolved, the dispute proceeds to mediation or litigation with your full documented record as evidence.
BCI: Negotiation support, forensic schedule testimony, expert documentation

Common Questions

SB 440 — Frequently Asked Questions

Does SB 440 apply to my project?
SB 440 applies to private construction contracts entered into on or after January 1, 2026 in California. If you signed a new construction contract after that date for a private works project, SB 440 applies. Public works projects are covered by separate existing legislation (Public Contract Code §9204).
What if I don't respond to a contractor's claim within 30 days?
Failure to respond constitutes a denial under SB 440 — but it does not protect you from interest penalties. If the claim is later found to include undisputed amounts, you'll owe 2% monthly interest from the date payment was due. Silence is not a safe strategy under SB 440.
We already have a project manager — why do we need BCI?
Most project managers are focused on day-to-day coordination. SB 440 claims require forensic schedule expertise, independent cost verification, and formal written responses that meet specific legal standards. BCI specializes in exactly this — owner-side project controls and claims defense that most general PMs aren't equipped to provide.
Can BCI help if a claim has already been submitted against us?
Yes — and the sooner the better. If you've received a formal SB 440 claim, you have a 30-day response window. BCI can perform rapid forensic schedule analysis, evaluate the claimed amounts, and prepare a defensible written response. Contact us immediately if you've received a claim.
How much does BCI's SB 440 protection cost?
BCI's fees depend on project size, scope, and the specific services needed. We offer a free initial consultation to assess your project and recommend the right level of support. In most cases, BCI's fee is a small fraction of the potential exposure from a single undefended SB 440 claim.
We're in preconstruction — is it too early to engage BCI?
Preconstruction is actually the ideal time to engage BCI. Contract review, baseline schedule development, and documentation protocols established before construction begins are your strongest protection under SB 440. Waiting until a claim is filed means you're already behind.
