Advertising another brokerage's listing in Arizona and Colorado: what the rules say

In Colorado, the state rule asks for the listing broker's written permission before you pass along another broker's advertising, and it asks you to name that broker's firm in a conspicuous manner. The rule text is quoted below, word for word, with a link to the official copy so you can check every line yourself.

For Arizona, this page points you to the official rule instead of quoting it, and the reason is written out in that section. Sources were checked on October 23, 2026. Rules change, so the official copy always wins over this page.

Colorado

The rule is Colorado Real Estate Commission Rule 6.10, Advertising, in the Commission's broker rules (4 CCR 725-1). The Division of Real Estate publishes it in Chapter 2 of the 2026 Colorado Real Estate Manual. Every quote in this section comes from that document.

Social media counts as advertising

Rule 1.2 defines the word. It reads, in part:

“Advertising may include, but is not limited to, business cards, brochures, websites, signage, property flyers, mailings (paper or electronic), social media, letterhead, email signatures, and contract documents.”

You need authority before you advertise a property

Rule 6.10.F opens with this:

“Brokers may not Advertise the availability or price of a property whether for sale or lease without authority from the owner or the owner’s Broker”

The next sentence speaks to the listing side:

“If such authority is requested, an owner’s Broker may not withhold the authority to advertise said property unless such authority is contradictory to instructions from the owner as memorialized in the Listing Contract or other writing.”

The four conditions for another broker's advertising

Rule 6.10.F.1 sets out how a broker may pass along another broker's advertising:

“A Broker may disseminate another Broker’s Advertising in the following manner:
a. A Broker must have the owner’s Broker’s written permission to disseminate the Advertising;
b. The Broker discloses, in a conspicuous manner, the owner’s Brokerage Firm;
c. The Advertising is accurate and not misleading to Consumers; and
d. The Advertising complies with subsection C. of this Rule.”

Subsection C, which condition d points to, begins:

“Brokerage Firms and Brokers are responsible for ensuring that all Advertising is accurate and complies with copyright laws and other applicable laws and regulations.”

Your own firm's name goes on it too

Rule 6.10.A.4:

“All Advertising must be done clearly and conspicuously in the name of the Broker’s Brokerage Firm.”

Read together, a post for a listing another firm holds carries two firm names: the one you work under, and the one that holds the listing. And the permission behind it is written, so the email you save is the record that you had it.

Arizona

Arizona's rule on advertising by a licensee is R4-28-502, in Title 4, Chapter 28 of the Arizona Administrative Code, the chapter for the State Real Estate Department.

This page does not quote it. The official copy is published by the Arizona Secretary of State, and that copy would not load for us when this page was checked. A rule quoted from anything other than the current official text is a rule that can be wrong, and a wrong rule on a page about compliance is worse than no quote at all. When the official copy can be read and checked line by line, the Arizona text goes here.

Read it yourself in the official text of Title 4, Chapter 28, and look for the subsections on the employing broker's name and on advertising property listed with someone else. The Arizona Department of Real Estate is the agency to ask. Your own designated broker is the first person to ask.

Your brokerage sits on top of the state rule

A state rule is the floor. Your brokerage can be stricter, and so can the rules of any association you belong to. Some brokerages encourage marketing outside the usual channels, some restrict it, and some forbid it. Ask your own broker first, then ask the listing side in writing for permission to market the listing, with the address, how long the permission runs, and any conditions they want. There is a walkthrough in how to ask a managing broker.

Where Listing AutomatEr fits

Listing AutomatEr is a desktop app for Mac and Windows that posts the listings you have permission to market to Facebook Marketplace on a schedule. On every post it writes your name as the agent marketing the home and credits the brokerage that holds the listing, from the brokerage on the listing record.

It does not obtain the permission for you, it does not decide whether a yes you got covers a given listing, and it does not make a post compliant on its own. Those stay with you and your broker. More on the lines it writes is in attribution and disclosure.

This is not legal advice. This page quotes a state rule so you can read it yourself. It is not a lawyer's opinion about your situation, and the official text, your brokerage, and your own lawyer are the authorities. Check them before you post.
