California's cancellation windows at a glance

California gives home-improvement buyers more cancellation protection than federal law alone requires, and it stacks several different windows depending on the buyer and the job:

Situation Cancellation window Source
Standard home solicitation contract (signed away from contractor's office) 3 business days Civil Code §1689.6(a)
Buyer is 65 or older 5 business days Civil Code §1689.6(a)
Personal emergency response unit 7 business days Civil Code §1689.6(b)
Repair/restoration of residential premises damaged by a disaster 7 business days Civil Code §1689.6(c)
Service/repair contract meeting §7159.10 conditions (price over $750, uninitiated contact, unnecessary add-ons, or early payment) 3 business days (5 for seniors) Bus. & Prof. Code §7159.10
Contract negotiated at contractor's fixed place of business No cancellation right under this statute CSLB guidance
Contract price under $25 Exempt CSLB guidance

These rights are layered on top of — not a replacement for — the federal FTC Cooling-Off Rule and, on financed jobs, TILA rescission. A contractor who only builds a contract template around the federal 3-day window will ship non-compliant paperwork the first time a senior buyer, a financed job, or a post-disaster repair comes through the door. See our companion national guide, The 3-Day Right to Cancel: What Home Improvement Contractors Must Do, for how the federal rules work.

The standard 3-day right

Business and Professions Code §7159 requires that a buyer's receipt of a signed copy of a home improvement contract "initiates the buyer's rights to cancel the contract pursuant to Sections 1689.5 to 1689.14, inclusive, of the Civil Code." Civil Code §1689.6(a) sets the baseline: the buyer may cancel "until midnight of the third business day... after the day on which the buyer signs" a compliant agreement.

This right applies to home solicitation contracts — agreements the buyer signs somewhere other than the contractor's regular place of business, such as the buyer's home or a job site. Per CSLB guidance on §7159, the right does not apply if:

The 5-day right for buyers 65 and older

The same subdivision — Civil Code §1689.6(a) — extends the cancellation window to 5 business days when the buyer is a senior citizen. This extension applies broadly — CSLB guidance confirms it covers home solicitation contracts, home improvement contracts, PACE assessment contracts, service and repair contracts, and seminar sales contracts alike.

The correct cancellation statement for a senior buyer, per Civil Code §1689.7, reads: "You, the buyer, may cancel this transaction at any time prior to midnight of the fifth business day after the date of this transaction." Using the standard 3-day language on a contract with a buyer 65 or older is a defect in the notice itself.

The 7-day disaster repair variant

Civil Code §1689.6(c) grants a longer, 7-business-day cancellation window for "a home solicitation contract or offer for the repair or restoration of residential premises damaged by a disaster," on top of any other right the buyer already has to revoke the offer. The same 7-business-day period applies to contracts for personal emergency response units.

What we could confirm: the statutory text extends the window to 7 business days for disaster repair/restoration contracts, and expressly makes that extension "subject to" Civil Code §§1689.14 and 1689.15.

What we could not confirm from the statute itself: whether a specific, formal state-of-emergency declaration (presidential, gubernatorial, or local) is a precondition to qualifying for the 7-day window. Some secondary summaries describe such a requirement, but the operative text of §1689.6(c) we reviewed references "a disaster" and defers additional conditions to the cross-referenced sections rather than spelling out a declaration requirement in that subsection. Contractors who plan to rely on the 7-day variant for post-disaster repair work should confirm the specific conditions in §§1689.14–1689.15 against their situation, or consult counsel, rather than assuming the extended window applies automatically to any storm, fire, or water-damage job.

Notice-form requirements

Two statutes work together here: Civil Code §1689.7 sets the general Home Solicitation Sales Act notice requirements, and Business and Professions Code §7159 layers home-improvement-specific requirements on top.

Required on every applicable contract:

How cancellation may be delivered: Civil Code §1689.6 recognizes written cancellation delivered by mail (effective when deposited, postage prepaid) or to the address specified in the contract. AB 1327 modernized this for 2026: the notice of cancellation may now also be sent by email, and — per the bill's provisions — may be conveyed orally by telephone in lieu of a written notice, with the seller required to publish an email address and phone number for that purpose.

When the clock starts

The cancellation period runs from the day the buyer signs a contract that complies with Civil Code §1689.7 — not from a later date the paperwork is filed, processed, or entered into a system. Business day counting excludes Sundays and federal holidays; Saturdays count as business days.

Worked example: sign on Friday

A homeowner (under 65) signs a standard home solicitation contract on a Friday:

Day Business day count
Friday (signing) Day zero — not counted
Saturday Business day 1
Sunday Skipped (not a business day)
Monday Business day 2
Tuesday Business day 3 — cancellation deadline is midnight Tuesday

For a buyer 65 or older signing the same Friday, the 5-business-day count runs through the following Thursday (Saturday=1, Monday=2, Tuesday=3, Wednesday=4, Thursday=5), again skipping Sunday. Any federal holiday landing inside either window pushes the deadline out by one additional business day.

Consequences of skipping the notice

Two separate consequences apply if a contractor fails to provide a compliant Notice of Cancellation:

  1. The cancellation right doesn't close. Civil Code §1689.7 states plainly: "Until the seller has complied with this section the buyer may cancel the home solicitation contract or offer." A missing or defective notice leaves the contract cancellable indefinitely, not just for 3 (or 5, or 7) days.
  2. It's a CSLB licensing issue. Business and Professions Code §7159(a)(6) allows the buyer to file a complaint with the Contractors State License Board when the required Notice of Cancellation isn't included in or attached to the contract. Separately, §7159(a)(5) makes the failure to provide required contract information, notices, and disclosures cause for discipline against the contractor's license — which can include a citation, license suspension, or revocation depending on the severity and history of the violation.

Why this matters beyond the paperwork

A defective or missing cancellation notice doesn't just create a licensing headache — it keeps the underlying contract cancellable, which affects everything downstream: draw schedules, material orders, subcontractor commitments, and financing tied to the job. Treating the notice as a formality rather than a condition of an enforceable contract is the single most common way contractors end up disputing a cancellation months after work has already started.
