Open house rules for New Jersey agents

What New Jersey asks of an agent at the door: the sign you have to post at the entrance or at the sign-in sheet, when a follow-up call counts as an unsolicited telemarketing sales call, when the buyer brokerage services agreement is due, and how a sign-in list has to be destroyed.

This is not legal advice

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

What has to be posted at your sign-in table?

New Jersey is one of the few states that writes the open house disclosure into the statute itself. At any residential showing that is generally open to the public you have to post a sign, either at the entrance or at the sign-in sheet, telling visitors that the brokerage firm hosting the open house represents the seller only and has no relationship with the prospective buyer. The section then sets out the exact words that sign has to carry, including a line warning visitors that anything they tell you is not confidential under New Jersey law and could be disclosed to the seller, and a line telling any visitor who is already exclusively represented to disclose that on the sign-in sheet. So print the statutory sign, put it where people actually stop to sign in, and add a field to your sign-in form asking whether the visitor already has a buyer's agent.

At any residential property showing that is generally open to the public, a sign shall be posted at the entrance or at a sign-in sheet clearly advising prospective buyers that the brokerage firm hosting the real estate open house represents the seller only and has no relationship with the prospective buyer

Can you call a visitor after the open house?

New Jersey has its own telemarketing statute, and whether your follow up is regulated turns on whether it counts as an unsolicited telemarketing sales call. The statute says a call is not unsolicited if it is made in response to the customer's express written request, or if it is made to an existing customer who has not told you to stop. A visitor who ticks a box on your sign-in sheet asking you to get in touch is giving you that written request, so word the box as a request for contact and keep the record of who ticked it and when. If a visitor leaves a number without asking to be contacted and is not already your customer, neither exception covers you, and the call is an unsolicited telemarketing sales call under the statute.

"Unsolicited telemarketing sales call" means any telemarketing sales call other than a call made: (1) in response to an express written request of the customer called; or (2) to an existing customer, which shall include the ability to collect on accounts and follow up on contractual obligations, unless the customer has stated to the telemarketer that the customer no longer desires to receive the telemarketing sales calls of the telemarketer.

Does a visitor have to sign a buyer agreement first?

No. The Consumer Protection Enhancement Act ties the buyer paperwork to when you start working for the buyer, not to when someone walks through the door. In a residential transaction the brokerage firm has to enter into a brokerage services agreement with the buyer before, or as soon as reasonably practical after, the firm starts rendering brokerage services to that buyer. Nothing in that section makes a signed agreement a condition of attending an open house, and the statutory open house sign in the same act assumes the person in front of you may have no agent at all. The moment the conversation turns into you working for that visitor, such as agreeing to show them other homes, paper it.

In a residential real estate transaction, a brokerage firm shall enter into a brokerage services agreement with the buyer before, or as soon as reasonably practical after, the firm commences rendering real estate brokerage services to, or on behalf of, the buyer.

How long can you keep the sign-in list?

New Jersey has no open house specific privacy rule, so a sign-in sheet is handled as a customer record under the state's Identity Theft Prevention Act. Once you are no longer keeping a visitor's details, the law requires you to destroy them so the personal information cannot be read or reconstructed, which for a digital list means actually deleting it rather than leaving an old export sitting in a downloads folder. The same act requires a business to notify New Jersey customers when computerized records holding their personal information are breached. Decide up front how long you keep a sign-in list, delete the spreadsheet copies you no longer need, and keep the live list in one system you can account for.

A business or public entity shall destroy, or arrange for the destruction of, a customer's records within its custody or control containing personal information, which is no longer to be retained by the business or public entity, by shredding, erasing, or otherwise modifying the personal information in those records to make it unreadable, undecipherable or nonreconstructable through generally available means.

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 New Jersey expects of you.
