The Arizona Preliminary 20-Day Notice: Who, When, and the Fourth Party
What ARS 33-992.01 requires before an Arizona mechanics lien is possible — the four people who must be served, the twenty days, the two ten-day duties the notice puts on the owner, and the thirty percent rule that quietly voids a notice nobody thought about again.
Why this notice exists
Section 33-992.01(B) is blunt about what the preliminary twenty day notice is: serving it is "a necessary prerequisite to the validity of any claim of lien". Not a courtesy, not a best practice. Without it there is no lien to record, however clearly you are owed.
The one exception in the same subsection is narrow: a person performing actual labor for wages does not have to give it. Everybody else furnishing labor, professional services, materials, machinery, fixtures or tools does.
Four people, and the fourth is the one that gets missed
Subsection (B) names the owner or reputed owner, the original contractor or reputed contractor, the construction lender if any, and — this is the one — the person with whom the claimant has contracted for the purchase of those items.
If you have worked in California, that fourth party is a trap. A California preliminary notice names the person who hired you on the face of the document; it does not require you to serve them. Arizona requires service on all four. A notice that went to three of them is a notice with a hole in it.
Subsection (G) is the relief: one notice covers everything you furnish for that building, and you do not send a fresh one every month. Two things break that, and they are in the next two sections.
The twenty days, and what a late notice still covers
Subsection (C) sets the clock: not later than twenty days after the claimant has first furnished labor, professional services, materials, machinery, fixtures or tools to the jobsite.
Subsection (E) is the part worth knowing before you panic. A person who did not give notice in the first twenty days is not shut out — they may give one later, and they are then entitled to a lien for what was furnished within the twenty days before service, and anything after it. Late costs you the front of the job, not the job.
Timing runs on service, and subsection (F) says service is complete at the time of the deposit of notice in the mail. Not on arrival. A notice posted on day nineteen and delivered on day twenty-three is on time.
What the notice must contain
- A general description of what you have furnished or will furnish, and an estimate of the total price (33-992.01(C)(1)).
- Your name and address (C)(2), and the name of the person who contracted for the purchase (C)(3).
- A description of the jobsite sufficient to identify it — a legal description, subdivision plat, street address, or location by known roads or landmarks (C)(4).
- The Notice to Property Owner in bold-faced type, in the words the statute writes, including the three options for protecting against a lien (C)(5).
- The two blocks subsection (D) puts in type at least as large as the largest type on the document: the owner has ten days to correct any inaccuracy or lose it as a defense, and ten days to hand over a copy of any recorded payment bond.
Subsection (I) takes the fear out of the typography: a notice that is otherwise compliant is not defective because the bold-faced type or the oversized type was not used. The words have to be there. The formatting is the statute followed properly, not a trap waiting to spring.
The thirty percent rule
Subsection (G) says the one-notice-covers-everything rule holds unless the actual estimated total price exceeds by thirty percent or more the total price in the notice you already gave. Go past that line and notice requirements must be met for the additional work.
This is the rule that voids notices served perfectly. A supplier estimates forty thousand in February, the job grows, and by August they have furnished sixty-five — sixty-two percent over — with one notice on file from February covering a number nobody looked at again. Subsection (H) gives some room in the other direction: a notice is not defective because later work exceeds the estimate by less than thirty percent.
Estimate generously, and diary the figure rather than the notice.
Proving you served it
Section 33-992.02 puts the proof in the recipient's hands first. The acknowledgment of receipt goes out with the notice — subsection (D) of 33-992.01 says it is inserted in the form itself — and a signed one coming back is your proof.
When it does not come back, and it often does not, the fallback is an affidavit by the person who did the mailing, showing the time, place and manner, available once thirty days have passed from the date of mailing. Attach the certificate of mailing to it, or the certified or registered mail receipt.
So the certificate is not paperwork for its own sake. It is the thing the affidavit is built on, which is why the service method matters as much as the date.
The habits that keep the right
- Serve all four. Build the list when you sign, not when the twenty days are running out.
- Use certified mail, or first class with a certificate of mailing — personal delivery is not on the statute's list, however sure you are that it arrived.
- Keep the certificate with the job file the day you send it. It is the affidavit's evidence thirty days later.
- Write the estimate down somewhere you will look again, and check it against the real total when the job grows.
- Record the first-furnishing date the day it happens. Every deadline in this chapter runs from an event, and the event is the thing nobody can reconstruct a year later.
