Open house rules for Maryland agents

What Maryland asks of an agent holding a property open: the Commission notice you post instead of handing out a form, what prior express written consent means for automated follow-up, when a buyer agreement is due, and why nothing a visitor says is confidential.

This is not legal advice

We are software people, not lawyers. This page is a plain reading of public Maryland 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 Maryland.

Do you have to tell open house visitors you represent the seller?

Yes, and Maryland writes the open house into the statute itself. In a residential transaction, Section 17-530 says a licensee holding a property open to the public complies with the disclosure requirement of that section by displaying, in a conspicuous manner, a notice to prospective buyers or lessees that the licensee present on the property represents the seller or lessor, and the same paragraph makes the Commission prepare and provide that notice. So use the Commission's open house sign and put it where visitors read it walking in, not on a side table behind the food. For anyone whose first contact with you is not the open house itself, the same section still requires the written disclosure no later than the first scheduled face to face contact, and where that first contact is not face to face, a seller's agent has to disclose through the medium in which the contact occurs that they represent the seller or lessor.

If a licensee is holding a property open to the public, the licensee complies with the disclosure requirements of this section if the licensee displays, in a conspicuous manner, a notice to prospective buyers or lessees that the licensee present on the property represents the seller or lessor.

Can you call or text a visitor after the open house?

Picking up the phone yourself and calling back a visitor who asked you to is one thing. Feeding the sign-in list into an autodialer or a system that plays a recorded message is another, and Maryland Commercial Law 14-4502 bars a telephone solicitation involving an automated system for the selection or dialing of telephone numbers, or the playing of a recorded message when the call connects, without the called party's prior express written consent. The same section also bars a solicitation call to someone between 8 p.m. and 8 a.m. in that person's time zone, and more than three calls to the same person in a 24 hour period on the same subject matter. The consent the statute asks for is prior, express and written, so if automated follow up is part of your plan, the consent line belongs on the sign-in form itself and has to be collected before the first automated call goes out.

Without the prior express written consent of the called party, a person may not make or cause to be made a telephone solicitation that involves: (i) An automated system for the selection or dialing of telephone numbers; or (ii) The playing of a recorded message when a connection is completed to the number called.

Does an open house visitor need to sign a buyer agreement?

Not to walk through the house. The Commission's own agency disclosure form tells buyers that if they are viewing a property and have not signed a Brokerage Agreement, that agent represents the seller, so touring a visitor around your listing does not make you their agent. The same form is equally blunt in the other direction: a buyer who wishes to have an agent represent them must enter into a written brokerage agreement. So keep helping visitors through the house as the seller's agent, and treat that written agreement as the line you cross before you start evaluating properties for one of them, preparing their offer, or negotiating in their best interest.

Is what a visitor tells you at the sign-in confidential?

No, and the Commission prints the warning for you. Its open house sign tells visitors on its face that any information they give the agent conducting the open house is not considered confidential under the Maryland Real Estate Brokers Act and could be disclosed to the seller of the property. The same sign tells them the agent conducting the open house represents the sellers and is required by law to promote the sellers' interests. That cuts both ways. You are free to pass what a visitor tells you to your seller, and you must never promise a visitor that what they say stays with you. Post the sign so it is read before anyone reaches the sign-in screen, and keep your questions to things you would repeat to the owner without flinching.

ANY INFORMATION YOU GIVE THIS AGENT IS NOT CONSIDERED CONFIDENTIAL under the Maryland Real Estate Brokers Act and could be disclosed to the seller of this property.

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 Maryland expects of you.
