Why You Need a California Construction Contract Lawyer
Construction contracts must comply with a complex web of statutes, regulations, and case law. Understanding these requirements is essential for protecting your business and ensuring smooth project execution.
SB 440 Transformed Change Order Disputes: The Private Works Change Order Fair Payment Act , codified at Civil Code section 8850, applies to contracts entered into on or after January 1, 2026. This law establishes a mandatory, step-by-step process for resolving claims on private construction projects. It requires owners to respond to claims within 30 days, pay undisputed amounts within 60 days, and participate in mediation before litigation can proceed. Failure to comply can trigger 2% monthly interest and give contractors the right to stop work.
SB 61 Limited Retention to 5%: On July 14, 2025, the Governor signed SB 61 into law, adding new Civil Code section 8811. With limited exceptions, this law caps retention at 5% of progress payments and 5% of the total contract value for private works contracts entered into on or after January 1, 2026. This represents one of the most significant legislative moves in favor of construction contractors in decades. Prime contractors must update their subcontract templates to reflect these new limitations.
Written Contract Requirements: Under California Business and Professions Code section 7164 , every contract for constructing a single-family dwelling to be retained by the owner for at least one year must be in writing and signed by both parties. The writing must include the contractor’s name, address, and license number; approximate start and completion dates; a legal description of the work location; and a mandatory “Mechanics Lien Warning” statement.
Licensing Compliance: Contractors must maintain proper licensing through the Contractors State License Board (CSLB) . Recent legislation has increased penalties for licensing violations and unlicensed contracting. Effective January 1, 2026, citations issued by the CSLB shall contain civil penalties ranging from $200 to $15,000. Starting July 1, 2026, minimum penalties for unlicensed contractors increase to at least $1,500.

Key 2026 Construction Law Updates
The 2026 construction law landscape has changed dramatically. Below are the most significant developments affecting construction contracts.
SB 61: Retention Cap on Private Projects
New Civil Code section 8811, effective for contracts entered into on or after January 1, 2026, limits retention on private works projects.
| Provision | Requirement |
|---|---|
| Retention Percentage | No more than 5% of a payment may be withheld as retention |
| Total Retention | Total retention cannot exceed 5% of the total contract value |
| Subcontract Flow-Down | Retention percentage in subcontracts cannot exceed the prime contract percentage |
| Exceptions | Does not apply to non-mixed-use residential projects under four stories; also excepted if subcontractor fails to provide payment/performance bond after proper notice |
The law cannot be waived, and prevailing parties in enforcement actions are entitled to reasonable attorney’s fees. Prime contractors must update their subcontract templates to reflect these new limitations.
SB 440: Private Works Change Order Fair Payment Act
New Civil Code sections 8850-8851, effective for contracts entered into on or after January 1, 2026, establish a mandatory claims resolution process.
Definition of “Claim”: A written demand for:
- A time extension (including relief from delay damages or penalties)
- Payment for work performed where payment is not otherwise provided
- Payment of an amount disputed by the owner
Three-Stage Resolution Process:
- Claim Submission and Owner Response (30 days): Owner must review claim and provide written response identifying disputed and undisputed portions. Undisputed amounts must be paid within 60 days.
- Informal Conference (if needed): If contractor disputes response or owner fails to respond, contractor may demand informal conference within 30 days. Within 10 business days after conference, owner must provide updated statement identifying remaining disputed portions.
- Mediation: Any remaining dispute must be submitted to non-binding mediation, costs shared equally. If parties cannot agree on mediator within 10 business days, contractor selects the mediator.
Contractor’s Right to Stop Work: If owner fails to comply with any step, contractor may suspend work after providing 30-day notice that payment is due, followed by 10-day notice of intent to stop work.
Interest Penalties: Undisputed amounts not timely paid bear interest at 2% per month (24% annually) . Disputed amounts later found to be owed bear interest from the date they would have been due if not disputed.
Non-Waivable: The rights under SB 440 cannot be waived in advance. However, after a claim arises, parties may agree to waive informal conference and mediation and proceed directly to dispute resolution.
SB 779: Increased Penalties for CSLB Violations
Effective January 1, 2026, CSLB citations shall contain civil penalties ranging from $200 to $15,000. Starting July 1, 2026, minimum penalties increase to:
- $1,500 for unlicensed contractor violations
- $500 to $3,000 for other specified violations
Essential Contract Elements Under California Law
Every construction contract should include these critical provisions.
Mechanics Lien Warning
Under Business and Professions Code section 7164, contracts for single-family dwellings must include a “Mechanics Lien Warning” statement in the required format. This warning informs owners that unpaid contractors, subcontractors, and material suppliers have the right to place liens on the property.
Insurance and Bonding
Contracts should clearly specify required insurance coverages, limits, and additional insured status. Additionally, contracts must address whether performance and payment bonds are required. Under section 7164, contracts must contain a notice in at least 10-point boldface type stating that the owner has the right to require the contractor to have a performance and payment bond.
Dispute Resolution
With SB 440’s mandatory procedures, dispute resolution clauses must integrate with the statutory framework. Consider whether arbitration or litigation will follow mediation, and ensure the clause provides clear guidance.
Prevailing Wage Compliance
Public works contracts must comply with prevailing wage requirements. Private projects may also have wage obligations depending on funding sources or local ordinances.
