SB 517 amends California’s home improvement contract rules to force clearer disclosure about subcontractor use and to tighten several contract-form and notice requirements. The bill requires contracts to include a clear Yes/No checkbox indicating whether subcontractors will be used, a standardized disclaimer, and a contractor obligation to provide a list of subcontractors (names, contact information, license numbers, and classifications) upon request; the same disclaimer must appear on change orders.
Beyond the subcontractor rule, SB 517 reaffirms the prime contractor’s administrative responsibility for project completion and makes omissions or failures to provide required contract information grounds for CSLB discipline. The statute also consolidates formatting and consumer protections — from downpayment caps and progress-payment disclosures to multiple cancellation notices and mechanics-lien warnings — creating a detailed compliance checklist contractors must follow or risk enforcement and customer disputes.
At a Glance
What It Does
The bill requires every home improvement contract to state whether subcontractors will be used (a checkbox), include a statutory disclaimer, and obligates the contractor to provide a list of subcontractors on request with names, contact details, license numbers, and classifications. It also codifies numerous form, notice, and typography requirements and confirms the prime contractor’s responsibility for project completion and disciplinary exposure.
Who It Affects
Every licensed California prime contractor doing home improvement work, home improvement salespeople, subcontractors who will be identified on request, homeowners and tenants hiring contractors, and compliance teams that maintain contract templates and process change orders.
Why It Matters
This statute shifts more transparency and administrative burden onto contractors and their sales teams while giving homeowners clearer tools to manage lien risk and exercise cancellation rights. For contractors it means updating templates, training sales staff, and adapting payment practices (for example, joint-check arrangements) to reduce lien exposure.

What This Bill Actually Does
SB 517 rewrites how home improvement deals must look on paper. At the front end, the contractor must deliver a signed, dated copy of the contract to the buyer before work begins; that delivery starts the buyer’s statutory cancellation window.
The contract must be legible and meet minimum type-size and heading requirements; several key phrases and headings must appear in boldface and in specified sizes so that cancellation and payment protections are obvious to the buyer.
The bill puts a new, explicit spotlight on subcontracting. Every contract must include a Yes/No checkbox answering whether subcontractors will be used.
If checked “Yes,” the contract must carry a mandated disclaimer telling the buyer that a list of subcontractors is available upon request and that the list will include names, contact information, license numbers, and classifications. When projects change, the same subcontractor disclaimer must appear on each change order.Payment mechanics are tightly regulated.
Downpayments are capped at the smaller of $1,000 or 10 percent of the contract price and must be shown under a “Downpayment” heading. Progress payments require a phase-by-phase schedule that ties dollar amounts to specific work and materials; the contract must state that it is unlawful for a contractor to collect payment for work not yet performed or materials not yet delivered.
The contract must also promise, upon satisfactory payment, an unconditional release from mechanics-lien claims relating to the paid portion of the work.SB 517 preserves and clarifies an array of required notices: commercial general liability and workers’ compensation disclosures (which may be attachments), a detailed mechanics-lien warning that explains preliminary notices and joint-check protection, a CSLB information notice, and customizable cancellation notices. The statute distinguishes three-, five-, and seven-day cancellation windows depending on where the contract was negotiated, the buyer’s age, and whether the work is disaster-related.
Finally, the bill makes failing to include required information — including the cancellation form — a disciplinary trigger and affirms that the prime contractor is administratively responsible for completing the project while not shielding subcontractors or salespeople from discipline for their own violations.
The Five Things You Need to Know
The contract must include a Yes/No checkbox stating whether a subcontractor will be used; if Yes, a statutory disclaimer about subcontractor lists must appear.
On request, the contractor must provide a list of subcontractors that includes each subcontractor’s name, contact information, license number, and license classification.
Change orders must carry the same subcontractor disclaimer when subcontractors will be used, and no change-order work is part of the contract unless the change order is in writing and signed before that work begins.
Downpayments are limited to the lesser of $1,000 or 10 percent of the contract price, and progress payments must tie specific dollar amounts to particular phases or services.
If the required Notice of Cancellation is not included or attached, the buyer may file a complaint with the Contractors State License Board (CSLB), and failure to provide required contract disclosures is cause for administrative discipline.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Scope, exceptions, and disciplinary authority
This subsection defines which projects fall under the home improvement contract rules and lists express exceptions (service/repair contracts governed by other sections, small fire-alarm installations under $500, and alarm-monitoring costs). It also makes any failure to include required information or notices a disciplinary violation and clarifies that the prime contractor is responsible, for administrative-discipline purposes, for completing the project in accordance with the contract, plans, and specifications — while preserving CSLB’s ability to discipline subcontractors or salespeople separately.
Definition of 'home improvement contract'
This provision defines the covered agreement broadly: written or oral, single or multiple documents, between contractor and owner or tenant, for work performed on a residence when the aggregate price exceeds $500. It explicitly covers salesperson-originated agreements and extends coverage to sales, installation, or furnishing of goods or services tied to home improvement.
Form and general content requirements
Subdivision (c) sets basic readability and formatting rules (legible writing, minimum 10-point type for body and headings unless otherwise specified) and mandates that the buyer receive a signed and dated copy before work starts. It requires a lien-release promise upon payment, mandates an integrated change-order form, requires notice that the owner can demand a performance and payment bond, and introduces the subcontractor-checkbox rule and the required subcontractor-disclaimer language. The provision also bars contractors from holding financial interest in any joint control arrangement they offer.
Prescribed contract fields and payment terms
This subsection lists the precise information every contract must contain: contractor name, address, license number, salesperson registration when applicable, a boldface “Home Improvement” heading, a 12-point boldface mandatory statement that buyers are entitled to a fully completed copy before work starts, a clearly labeled contract price, finance charge disclosure, a detailed project description (pool plans must include scale drawings), and strict downpayment and progress-payment formats — including the exact downpayment notice text and a 12-point boldface warning that collecting payment for uncompleted work is unlawful. It also requires the contract to state approximate start and completion dates and to incorporate documents specifically listed by the parties.
Required notices and cancellation rights
Subdivision (e) prescribes a suite of notices that must accompany the contract or be attached: commercial general liability and workers’ compensation notices (with selectable text depending on the contractor’s coverage), a detailed notice explaining limits on enforceability of extra or change-order work, an extended mechanics-lien warning that explains preliminary notices and recommends joint checks, a CSLB informational notice, and the varying cancellation notices — three-day (or five-day for seniors) and seven-day for disaster-related repair contracts — together with detachable ‘Notice of Cancellation’ forms in the same language used in the sales presentation.
Applicability of five-day cancellation rule
This short clause notes the effective application of a five-day right to cancel added to paragraph (6) of subdivision (e) and ties it to contracts entered into on or after January 1, 2021. It is an applicability statement embedded in the statutory text rather than a procedural rule.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Homeowners and tenants — get clearer, standardized disclosures about whether subcontractors will work on their property and how to obtain subcontractor contact and licensing details, better tools to manage mechanics-lien risk, and clearer cancellation and payment-protection language.
- Title companies and lenders — benefit from improved transparency about subcontractors and lien risk, which can reduce surprise liens and speed underwriting and closing when projects are financed.
- CSLB and regulators — gain a cleaner enforcement hook because failures to include specified contract content are express grounds for discipline, simplifying complaint handling and compliance review.
Who Bears the Cost
- Prime contractors — face increased compliance costs: updating contract templates, training sales staff on the checkbox and cancellation procedures, maintaining accurate lists of subcontractors, responding to requests for subcontractor information, and increased exposure to discipline for form failures.
- Small subcontractors — may face greater scrutiny and more frequent direct contact from homeowners and title companies; being named on a list may lead to more administrative inquiries and pressure to maintain immaculate licensing and contact records.
- Contract management and legal teams — will need to adapt systems (CRM, e-signature, change-order workflows) to capture checkbox responses, attach disclaimers to change orders, preserve proof of delivery of the cancellation form, and ensure font/typeface compliance.
Key Issues
The Core Tension
The central dilemma is balancing stronger consumer protections and lien-avoidance transparency against the compliance burden and liability consolidation imposed on prime contractors: the bill helps homeowners understand who can lien their property, but it also concentrates operational risk on contractors — potentially increasing costs, discouraging flexible subcontracting, and creating enforcement disputes over form minutiae.
SB 517 advances homeowner transparency but creates practical and legal frictions. Requiring subcontractor disclosure and an on-request list helps homeowners identify parties who can place mechanics liens, but it does not automatically provide subpoena-like verification; contractors may struggle to ensure the accuracy of license classifications and contact details for dozens of subs on busy jobs.
The law puts the burden on the prime contractor to produce compliant paperwork and to be administratively responsible for project completion, which will likely raise insurers’ and sureties’ attention and may increase costs for contractors with large subcontractor networks.
The bill’s many formatting and notice mandates are precise (type sizes, boldface language, detachable cancellation forms, identical-language requirements) and create a second-order compliance task: proof-of-delivery and preservation of the exact form presented to the buyer. Enforcement will hinge on administrative proof that a specific required phrase, checkbox, or detachable cancellation form was omitted — a factual showing that can be messy.
The statute also leaves a number of operational questions unresolved: when buyers may request the subcontractor list (at contract signing only or later), whether electronic delivery satisfies all detachable-form requirements in every context, and how CSLB will treat minor typographical deviations versus substantive omissions.
