Arizona Preliminary Twenty-Day Notice for Concrete & Flooring Contractors
In the heart of Arizona's booming Phoenix metro, the dual-phase concrete and flooring notice trap is a common pitfall. As the East Valley cities like Mesa and Chandler experience explosive growth, subcontractors often find themselves pouring slabs for new-construction residential and commercial projects, only to return months later for finish flooring like tile or LVP. The desert heat accelerates cure times, making it crucial to manage schedules tightly. From rebar and slab on grade to vapor barriers and polished concrete, Arizona's rapid project pace demands meticulous attention to notice requirements from the outset.
Arizona has one of the broadest preliminary notice requirements in the country. Missing the deadline eliminates lien and payment bond rights — and unlike most states, even general contractors must file.
The Deadline
| Notice type | Preliminary Twenty-Day Notice |
| Governing statute | A.R.S. § 33-992.01 |
| Deadline | 20 days from first furnishing of labor, services, or materials |
The deadline is strictly enforced.
When Does the Clock Start for Concrete & Flooring Contractors?
In the Phoenix metro's fast-paced new-construction environment, concrete subs often complete slab work before a building is even framed, only to return months later for interior finishes like tile or LVP. This pattern is typical in Arizona, where early deliveries of rebar or wire mesh are staged in the desert heat days before forming begins. Such early activity marks the start of the notice clock, long before finish scopes are awarded.
The exact legal definition of "first furnishing" is set by A.R.S. § 33-992.01. This operational description does not substitute for the statutory definition.
Worked Example: Gilbert — slab-on-grade pour and later LVP finish flooring on a 24,000 sq ft light industrial build in the East Valley
On a brisk January morning in Gilbert, our crew delivered rebar and wire mesh to a light-industrial site, marking the start of a slab-on-grade pour. The cool morning hours were perfect for forming the slab perimeter before the Arizona sun intensified. This was the first concrete work on the project. Months later, the GC awarded the LVP finish-flooring scope, but our office didn't flag the notice requirement until then. By that time, the early concrete phase had been completed and billed for months.
| Event | Date |
|---|---|
| First furnishing | January 13, 2025 |
| Notice must be served by | February 2, 2025 |
| Deadline | 20 calendar days (A.R.S. § 33-992.01) |
If the notice is not served by February 2, 2025, lien rights are at risk regardless of work completed or amounts unpaid.
Three Ways Arizona Concrete & Flooring Contractors Lose Their Lien Rights
N. The East Valley New-Construction Trap
In the rapidly growing East Valley, concrete slab work is often awarded in the shell package, while finish flooring is part of a separate interior package months later. Subcontractors working both phases may mistakenly tie notice requirements to the later finish-scope award date, overlooking the initial concrete work.
N. Arizona Summer Heat Scheduling
Concrete subs in Arizona often rush flatwork during early morning shifts to avoid the extreme heat. This accelerated schedule can lead to misremembering the first-furnishing date, crucial for notice compliance.
N. Vapor Barrier and Rebar Delivery
Delivering materials like vapor barriers and rebar to an Arizona site in advance of forming, even in the desert heat, constitutes first furnishing. These early deliveries start the notice clock, regardless of when forming begins.
Who Must File?
Virtually all claimants, including subcontractors, material suppliers, equipment lessors, and specialty contractors. Arizona has one of the broadest filing requirements in the country.
Who Is Exempt?
Laborers who are employees of the direct contractor or a subcontractor (wage earners).
How to Serve the Notice
The notice must be served by certified mail, registered mail, or personal delivery to the owner, the direct contractor (general contractor), and the construction lender (if applicable).
Statutory Notice Text
The following text must appear on the notice verbatim. Arizona statute requires this notice text to be rendered in BOLD face type.
NOTICE: THIS IS NOT A LIEN. This is a notice required by Arizona law to be given within twenty days of first supplying labor, professional services, materials, machinery, fixtures or tools to a construction project. It does not mean there is a problem with payment. This notice protects the right to file a lien or assert a claim against a payment bond if payment is not received.
What Happens When a Arizona Concrete & Flooring Sub Doesn't File
In Mesa, a subcontractor took on a dual-phase scope at a retail center, starting with foundation flatwork in the sweltering Arizona summer. The crew laid rebar and vapor barriers before pouring the slab, racing against the clock to finish before the midday heat. Months later, they returned to install tile flooring, only to realize the notice clock had started ticking back during the initial concrete phase. The gap between phases led to oversight, leaving the finish scope unprotected. This common scenario in Arizona's construction landscape underscores the importance of tracking notice requirements from the start.
Concrete & Flooring-Specific Questions
We poured the slab on a Gilbert commercial job early in the year and came back six months later when the GC awarded us the LVP flooring scope. Did our clock reset when the flooring contract was signed?
In Arizona, the notice clock starts with the first phase of work, such as the initial slab pour. The later award of the flooring contract does not reset the clock, so it's important to track from the earliest work.
On an Arizona job, we delivered rebar and wire mesh to the site three days before forming started because of an early-morning summer pour schedule. Did that delivery start our notice clock?
Yes, in Arizona, delivering materials like rebar and wire mesh to the site constitutes the start of your notice clock, even if forming begins later. The desert heat and scheduling considerations don't alter this timing.
We do only tile and LVP work — no concrete. On an Arizona new-construction project, when does our clock start?
For Arizona projects where you handle only finish flooring, your notice clock starts with the first delivery or installation related to your scope, such as tile or LVP, not the earlier concrete work.

What is the "30% Rule" for Arizona Preliminary Notices?
