Open house rules for Arizona agents

What Arizona expects when you hold a house open: saying plainly that you work for the seller while still dealing fairly with everyone walking through, the rule that reaches a cold call to a mobile number, when a written employment agreement actually matters, and who supervises the sign-in list.

This is not legal advice

We are software people, not lawyers. This page is a plain reading of public Arizona sources, gathered so you can go read them yourself. Rules change, and how any rule applies to your situation is a question for your broker, your association, or an attorney licensed in Arizona.

Who do you represent at the door?

At an Arizona open house you are almost always there as the seller's agent, and the Commissioner's Rule is explicit that your fiduciary duty runs to your client while you still have to deal fairly with the other parties to the transaction. Say early and plainly that you represent the seller, so a visitor does not assume that what they volunteer about their budget, their financing or their moving deadline is being held in confidence. It is not. The same rule requires you to take reasonable care to obtain information that is material to your client's interests and relevant to the contemplated transaction, and to communicate it accurately back to your seller. If a visitor asks you to represent them as well, stop there. The rule bars you from representing more than one party to a transaction without the prior written consent of all parties, so that consent has to be in hand before you act for both.

A licensee owes a fiduciary duty to the client and shall protect and promote the client's interests. The licensee shall also deal fairly with all other parties to a transaction.

Can you call a visitor after the open house?

Arizona's telephone solicitation article exempts a person acting within the scope of a Title 32 license from most of its requirements, but it does not exempt them from A.R.S. 44-1278. That section lists an unsolicited telephone sales call to a mobile or paging device as an unlawful practice, and an open house sign-in sheet is mostly cell numbers. So at the door, get the visitor to affirmatively ask you to follow up and record that they did, rather than treating a written-down phone number as consent by itself. The moment anyone tells you to stop calling, stop. The safe harbor in that same section is narrow: it applies only where you had written procedures, trained your people on them, maintain a no call list of everyone who asks not to be contacted, keep every do not call request for at least ten years, and the call that got through was the result of an error.

Intentionally make or cause to be made any unsolicited telephone sales call to any mobile or telephone paging device.

Do you need a signed buyer agreement before showing a visitor around?

Arizona statute does not require one. It says in terms that a real estate employment agreement is not required for a licensee to represent a party in a transaction, so walking an open house visitor through the house does not by itself put you offside of state law. The catch is getting paid. The same statute defines a real estate employment agreement as a written agreement by which a broker becomes entitled to compensation, and requires every such agreement to be written in clear and unambiguous language, to set out all material terms including the terms of broker compensation, to show definite dates of inception and expiration, and to be signed by all parties. So if you intend to be compensated for working with that visitor, get it signed before you start working for them. Your MLS and your brokerage may impose their own written-agreement requirement that is stricter than the statute, so confirm your office policy on top of this.

A real estate employment agreement is not required for a licensee to represent a party in a transaction.

Who owns the sign-in list, and what can you do with it?

Treat the visitor list as brokerage business, not your private database. Arizona makes your employing broker and designated broker responsible for supervising your licensed activity, and reasonable supervision includes establishing and enforcing written policies covering the filing, storing and maintaining of documents pertaining to transactions and covering advertising, plus reviewing and inspecting advertising and marketing by licensees in the broker's employ. One carve-out is worth knowing: a single-office brokerage with a designated broker, no more than one other licensed person and no more than one unlicensed person is not required to develop those written policies, so ask rather than assume yours exist. Either way, before your first open house get your broker's position on where sign-in data is stored, who is allowed to see it, and which follow-up campaigns are approved, then keep the data inside a system your broker has actually signed off on. Separately, A.A.C. R4-28-502(E) requires all advertising to identify, in a clear and prominent manner, the employing broker's legal name or a d.b.a. name on the broker's license certificate, so the follow-up emails and mailers you send off that list have to name the brokerage.

An employing broker and a designated broker shall exercise reasonable supervision and control over the licensed activities of licensees and others in the employ of the broker.

How this page is put together

  • Every claim above carries a link to a primary source, plus the exact words from that source that support it. If a claim cannot be quoted, it is not on this page.
  • Each claim shows the date a human last opened that link and confirmed the quote still says what it says.
  • We only cover what we could source. A topic you were hoping to find may be one we have not confirmed yet, so treat this as a starting point rather than a complete list of everything Arizona expects of you.
