BPC §7159 — Home Improvement Contract Requirements
Cal. Bus. & Prof. Code §7159 · A statute every California home-remodel job lives under · Verified April 2026
California Business and Professions Code §7159 is the statutory backbone of consumer protection in residential remodeling. It applies to every home improvement contract over $500 between a contractor and a property owner or tenant, and it dictates what the contract must contain, how the contract must look (font sizes, headings, specific notices), and how much money the contractor can take up front. Failure to comply isn't just a paperwork issue — under §7159 itself and the related §7159.5, contract noncompliance is grounds for CSLB discipline, and combined with §7031, an unlicensed or non-compliant contractor can lose the entire amount paid. This page reproduces the most-cited subsections of §7159 in full and annotates the practical requirements.
When §7159 Applies
The $500 Threshold
§7159 governs any "home improvement contract" — meaning an agreement between a contractor and an owner or tenant for home-improvement work — when the aggregate contract price exceeds $500, counting all labor, services, and materials. Below $500, the statute does not apply, though general contracting and licensing rules still do.
Multiple smaller contracts on the same property between the same parties can be aggregated to cross the $500 threshold if a court finds they were part of a single project. Contractors sometimes try to structure work as multiple sub-$500 contracts to escape §7159; this gambit rarely survives careful review.
"Home Improvement" — What Counts
BPC §7151 defines "home improvement" broadly: repairing, remodeling, altering, converting, modernizing, improving, or adding to residential property, including detached structures, fixtures, and improvements adjacent to the residence. New residential construction (not improvement of an existing structure) is governed by a different framework — chiefly Civil Code §895 et seq. (the Right to Repair Act, see our SB 800 deep-dive).
Key Statutory Text — Subdivisions (a) and (d)
The text below is the operational core of §7159 — the definition of contract scope and the mandatory contract requirements. Subdivision labels are bolded for navigation; emphasis (italics) is not in the original statute.

Mandatory Notices Required by Subdivisions (c) and (e)
§7159 requires that every home improvement contract contain — in close proximity to the signature lines, in specified font sizes — a series of mandatory verbatim notices. The most important of these:
The Mechanics Lien Warning
A mandatory consumer notice warning the homeowner that subcontractors and material suppliers may record mechanic's liens against the property under Civil Code §8400 even if the homeowner has paid the prime contractor in full. The notice must explain unconditional waivers, the importance of asking for a list of subcontractors, and the homeowner's right to issue joint checks. Font requirement: at least 10-point boldface type.
The Three-Day Right to Cancel
Subdivision (e) and Civil Code §1689.6 give a homeowner a three-business-day right to cancel any home improvement contract signed at the homeowner's residence, without penalty. The notice of right to cancel must be attached to the contract in at least 10-point type, and the homeowner's signature on the contract triggers the three-day clock. Senior citizens (65+) and disaster-area residents get expanded cancellation rights under Civil Code §§1689.7 and 1689.14.
The Commercial General Liability (CGL) Disclosure
The contract must include a notice telling the owner whether the contractor maintains commercial general liability insurance, and if so, the name and address of the insurance carrier. If the contractor does not maintain CGL insurance, the notice must say so. This lets the owner make an informed decision before signing.
The Workers' Compensation Disclosure
If the contractor has employees, the contract must disclose the workers' compensation insurance carrier and policy number. If the contractor has no employees and therefore no workers' compensation insurance, the contract must disclose that fact.
The Down Payment Limit — A Statutory Bright Line
One §7159 rule causes more disputes than any other: the down payment cap.
10% or $1,000, whichever is less
A contractor may not require or accept a down payment greater than $1,000 or 10% of the contract price, whichever is less. This is an absolute statutory ceiling that applies regardless of contract terms, regardless of what materials the contractor needs to purchase, and regardless of what the homeowner is willing to pay.
The narrow exception: subdivision (d) allows a "swimming pool" exception with somewhat different rules, but for ordinary home improvement contracts the $1,000/10% rule is hard. A contractor who took a $5,000 down payment on a $30,000 kitchen remodel is in violation even if the homeowner happily wrote the check.
Practical implication: progress-payment scheduling has to do the work that down payments used to. Contractors structuring large jobs use carefully-tied progress payments to materials delivery, permit approval, and milestone completion to maintain cash flow without violating §7159.
Leading Case Examples
Asdourian v. Araj
(1985) 38 Cal.3d 276
The California Supreme Court addressed whether a contractor's violation of the written-contract requirements in the home improvement statute's predecessor automatically barred recovery. The Court held that the statute's consumer-protection purpose is central and that, in some circumstances — particularly where both sides are sophisticated construction actors — a contractor may still recover despite technical noncompliance. Asdourian underscores that §7159 violations are not mere technicalities, but also that courts look closely at who the statute is intended to protect.
Davenport & Co. v. Spieker
(1994) 26 Cal.App.4th 1315
The Court of Appeal applied Asdourian's reasoning to determine whether a contractor could recover for work performed under change orders that did not comply with §7159's writing requirements. The court emphasized that not every §7159 violation renders a contract void, and examined the parties' sophistication and the nature of the violation in deciding whether to permit recovery. Davenport is a leading application of Asdourian's flexible illegality analysis in the §7159 context.
Hinerfeld-Ward, Inc. v. Lipian
(2010) 188 Cal.App.4th 86
The court held that the excessive down payment was actionable by the homeowner as a breach of statutory duty, triggering damages under Business and Professions Code section 7160, rather than through a section 7031 disgorgement theory. Hinerfeld-Ward illustrates how a §7159 violation can support a §7160 statutory-damages claim and, where the contractor is unlicensed, may operate alongside section 7031's separate disgorgement remedy.
Practical Impact
For a homeowner, §7159 is the consumer-protection statute. If a contract is poorly drafted, missing required notices, or asks for an excessive down payment, the homeowner generally has leverage that includes: refusing to pay further sums without correction, terminating the contract under the three-day cancellation right (if applicable), filing a CSLB complaint, and bringing a civil action under §7160 for damages. Most §7159 disputes resolve when the homeowner produces the contract and the contractor realizes their template was non-compliant.
For a contractor, the practical move is template compliance: have a §7159-compliant contract reviewed by California construction counsel, use it on every job, attach the right notices, never take more than the statutory down payment limit, and document change orders in writing before any out-of-scope work begins. Many CSLB enforcement actions begin with a homeowner complaint that started as a §7159 issue.

Frequently Asked Questions
Does §7159 apply if the contract is oral?
The statute by its terms covers oral and written contracts over $500, but it requires that the agreement "shall be in writing and signed by the parties to the contract prior to the commencement of work." An oral contract over $500 violates §7159 from the moment work commences. The contractor may still recover under common-law theories if specific exceptions apply, but the violation is a defense the homeowner can raise and grounds for CSLB discipline.
Can the down payment be more than $1,000 if the project costs millions of dollars?
No. The cap is "$1,000 or 10 percent of the contract price, whichever is less." For a $50,000 contract, 10% is $5,000 — but $1,000 is less, so the cap is $1,000. For any contract over $10,000, the cap is $1,000 flat. This is one of the most counterintuitive provisions in §7159 and one of the most violated. Larger projects use progress-payment scheduling, not larger down payments.
Does §7159 apply to a commercial property owner who is also acting as the contractor's customer?
Courts treat §7159 as a consumer-protection statute aimed primarily at residential homeowners. In Asdourian v. Araj (1985) 38 Cal.3d 276, the Supreme Court held that technical violations of the statute's predecessor did not automatically bar recovery where both parties were sophisticated construction-industry actors dealing at arm's length. In practice, a commercial property owner who is a repeat player in construction transactions may find courts less receptive to strict §7159-based defenses than a true consumer would be, but outcomes remain highly fact-specific.
What's the difference between a §7159 home improvement contract and a §7159.10 service and repair contract?
The service-and-repair framework (BPC §§7159.10–7159.14) is a parallel set of rules for smaller, time-limited jobs typically priced under $750 — emergency plumbing, appliance repair, similar reactive work. §7159.10 has its own contract requirements that are less burdensome than full §7159 requirements but still require written documentation. The categories don't overlap: a job is either a "home improvement contract" under §7159 or a "service and repair contract" under §7159.10, depending on the nature and price of the work.
Can a contractor lose their CSLB license over a §7159 violation?
Yes. BPC §7159.5(a) makes failure to comply with §7159 cause for discipline. CSLB enforcement can include citations, license suspension, or in serious or repeat cases, license revocation. The agency typically issues citations for first-time technical violations and escalates from there. A complaint from a homeowner about a §7159 violation is one of the most common ways an enforcement file gets opened.
I'm a contractor and my existing contract template wasn't drafted by an attorney. What should I do?
Have it reviewed by California construction counsel. The cost is modest relative to the exposure: a non-compliant template used across 50 jobs creates 50 potential §7159 problems, any one of which could escalate to a CSLB enforcement action, a §7160 civil suit with attorney fees, or a §7031 disgorgement claim.
