The “90-day notice” myth in Arizona dwelling-defect claims

Search “Arizona construction defect notice” and you will still find blogs, contract-review sites, and AI summaries saying buyers must give builders 90 days’ written notice before filing a construction-defect lawsuit. That shorthand is widespread — and it is a poor description of the current Purchaser Dwelling Act text.

What the live statute says

Under A.R.S. § 12-1363:

1. Before filing a dwelling action, the purchaser must give the seller written notice by certified mail, return receipt requested, specifying the basis of the claim in reasonable detail (itemized defects, locations, impairment, street address).
2. The seller (and construction professionals) may inspect. The purchaser must make the dwelling available not later than ten days after an inspection request.
3. Within sixty days after receiving the notice, the seller must send a good-faith written response by certified mail. That response may include intent to repair/replace or monetary compensation.
4. If the seller does not respond within sixty days, the purchaser may file a dwelling action.
5. If the seller intends to repair, the statute sets coordination timelines (including efforts to begin work on a commercially reasonable schedule) and says the seller is not entitled to a release solely for making repairs — though parties may negotiate a release for money or other consideration.
6. During the notice/repair process (and for thirty days after substantial completion of repair), applicable limitations and repose periods are tolled for the noticed defects.

There is no “wait 90 days after notice, then sue” countdown written as the core rule in the current § 12-1363 framework. The controlling response clock in the statute text is 60 days.

Why the “90 days” line keeps circulating

Older secondary summaries, out-of-state comparisons, and contract-review sites often compress notice-and-repair regimes into a single “90-day notice” slogan. Some Arizona builder contract explainers still repeat that number even while citing the Purchaser Dwelling Act. When blogs disagree with azleg.gov, cite azleg.gov.

What this myth does not change

• You still generally need notice and a repair opportunity before many civil dwelling actions (life/safety and other statutory exceptions exist — read §§ 12-1361–1362).
• Skipping the process can get a dwelling action dismissed, and a late refile can be time-barred (§ 12-1363(P)).
• An ROC complaint is a different path with a different clock (commonly two years from close or occupancy for new homes under the notice required by A.R.S. § 12-1365). The Purchaser Dwelling Act does not replace the ROC process.
• Arbitration clauses in your purchase contract can still move the civil fight into arbitration even after you complete notice/repair steps.

Practical homeowner translation

Outdated / shorthand claim	Better reading of current § 12-1363
“Give 90 days’ notice before you can sue.”	Send detailed certified-mail notice; seller has 60 days to respond.
“Nothing happens until 90 days pass.”	Inspection access, repair offers, and tolling can all start immediately after notice.
“Warranty portal ticket = PDA notice.”	Portal tickets help documentation; PDA notice has formal certified-mail and content requirements.
“ROC filing covers the PDA.”	Different forums. Confirm which path (or both) fits your goals and deadlines.

Documentation tips that still matter

• Keep the certified-mail receipt and a complete copy of what you sent.
• Itemize each defect with location and how it impairs the home — the statute’s “reasonable detail” definition is specific.
• Photograph before and after any repair attempts.
• Calendar the seller’s 60-day response deadline the day notice is received (and keep proof of receipt).

AZ HomeShield is built to hold those photos, tickets, and dates in one timeline so you are not reconstructing history from text threads a year later.
