“You signed away the implied warranty” — Arizona Zambrano fact-check
Fact-check of builder talking points that an express limited warranty or purchase-contract disclaimer wipes out Arizona’s implied warranty of workmanship and habitability. Zambrano (Ariz. 2022) generally blocks that waiver.
Published Updated 9 min read
Closing packets often stack two messages: a glossy Builder’s Limited Warranty booklet, and dense purchase-agreement language that disclaims implied warranties of merchantability, habitability, and workmanship. Sales and warranty desks then treat the booklet as the whole story. Arizona’s Supreme Court has already answered that package.
This guide sticks to Zambrano v. M & RC II LLC (Ariz. 2022) and how it sits next to ROC and Purchaser Dwelling Act paths. It is educational, not advice for your claim.
Myth: “You initialed the disclaimer — so implied warranty is gone.”
What’s true: Many Arizona new-home contracts still contain bold disclaimer / waiver paragraphs. Buyers often initial them. Express limited warranties (sometimes administered by third-party warranty administrators) still control how the builder’s portal triages day-to-day tickets.
What’s not true: Initialing that language automatically erases Arizona’s common-law implied warranty of workmanship and habitability. In Zambrano, the Arizona Supreme Court held that public policy prohibits agreements that disclaim and waive that implied warranty and replace it with an express warranty. The Court refused to carve out a “sophisticated buyer” exception.
In plain English: a one-year (or multi-stage) booklet can be real for portal process — and still not be the only legal layer after closing.
Myth: “The express warranty is better protection, so the waiver is fine.”
What’s true: Express warranties can be useful. They often define claim windows, finish tolerances, and how to submit tickets. Keeping a dated portal record still matters.
What’s not true: “Better” marketing copy makes a waiver enforceable. Zambrano involved a lengthy limited-warranty product marketed as layered builder protection. The Court still weighed the public policy behind the implied warranty — protecting buyers from latent defects that a reasonable pre-purchase inspection would not catch — and refused to enforce the disclaimer/waiver.
Latent defect timing is why Arizona climate issues (stucco movement, monsoon drainage, roof underlayment shortcuts) keep showing up months after punch lists close. See Arizona climate and new-home defects.
Myth: “If the booklet says one year, year two is too late for everything.”
What’s true: Many express workmanship stages end at twelve months (with shorter stages for finishes, landscaping, or appliances). Missing a booklet stage can change how the warranty desk responds.
What’s not true: “Past warranty” sales language ends every Arizona path. Separate tracks still include:
| Track | What it is | Typical clock (verify live sources) |
|---|---|---|
| Express limited warranty | Contractual portal process | Often 1 year / staged shorter windows |
| ROC complaint | Administrative workmanship enforcement | Two years from close of escrow or occupancy (A.R.S. § 12-1365) |
| Implied warranty | Common-law workmanship & habitability (Zambrano) | Subject to limitations / repose — not the booklet alone |
| Purchaser Dwelling Act | Civil notice-and-repair before many lawsuits | A.R.S. § 12-1363 process + § 12-552 repose |
Deep dives: ROC window vs civil claims, Arizona new-home warranty basics, PDA tolling, PDA dismissal trap.
What Zambrano does not say
- It does not guarantee you win every dispute or recover every dollar.
- It does not erase arbitration clauses, Purchaser Dwelling Act notice duties, or statute-of-repose outer limits.
- It does not turn an ROC complaint into a lawsuit (or the reverse).
- It does not force a warranty desk to accept your inspector’s PDF as the portal ticket — portal rules and legal rights are different questions (independent inspections guide).
Practical defaults when you hear “you waived it”
- Ask for the waiver language in writing — page, paragraph, and any “replaced by express warranty” sentence.
- Keep documenting with dated photos, rooms, ticket numbers, and repair visits anyway.
- Calendar three clocks separately: booklet stages, two-year ROC window, civil repose/limitations.
- Do not treat a closed portal ticket as proof that implied-warranty or ROC analysis is impossible.
- Talk to counsel before filing a contested dwelling action — notice-and-repair mistakes can dismiss a case (§ 12-1363(P)).

False as a complete picture
In Zambrano v. M & RC II LLC (Arizona Supreme Court, 2022), the Court held that public policy generally prohibits disclaiming and waiving the implied warranty of workmanship and habitability — even when the builder offers an express limited warranty as a substitute. Express booklets still matter for portal process; they do not automatically erase implied-warranty, ROC, or Purchaser Dwelling Act layers.
