How MLSs Work in New Jersey: GSMLS, NJMLS, Bright and the Regional Systems

The short answer: A Multiple Listing Service (MLS) is a shared database where brokers post their listings so agents at other firms can find homes for their buyers. NJ REALTORS® lists eight MLSs serving New Jersey, including Garden State MLS, New Jersey MLS and Bright MLS (NJ REALTORS®, MLSs). Each MLS sets its own rules, but New Jersey's real estate rules sit on top of them. One example: listing brokers must notify the MLS within 48 hours of a new listing (N.J.A.C. 11:5-6.4(f)).

If you want to know which MLS or REALTOR® board serves a particular county, see our REALTOR® boards by county guide. This page explains how an MLS actually works.

What is an MLS?

NJ REALTORS® describes New Jersey's MLSs as "databases that allow REALTORS® to help listing brokers work with buyers' agents to sell homes" (NJ REALTORS®, MLSs). An MLS isn't a government agency, and it isn't the same thing as a REALTOR® board, even when the two share an address. MLS rules also don't replace the state's rules. Garden State MLS says so directly: its rules "do not alter any obligations otherwise imposed on real estate licensees under New Jersey law," and state and federal law control if the two conflict (GSMLS Rules and Regulations, Preface).

Which MLSs operate in New Jersey?

NJ REALTORS® lists these eight (NJ REALTORS®, MLSs):

• All Jersey MLS (formerly Central Jersey MLS)
• Bright MLS
• Cape May County MLS
• Garden State MLS (GSMLS)
• Monmouth Ocean Regional MLS
• New Jersey MLS (NJMLS)
• Realty MLS
• South Jersey Shore Regional MLS

Bright MLS, for example, is headquartered in Maryland and lists New Jersey REALTOR® associations such as NEXUS and Mid Jersey among its associations (Bright MLS, Our Associations). The county guide linked above has the addresses and coverage we could verify.

How does a listing get into the MLS?

It starts with the listing agreement. New Jersey requires any listing agreement that puts a property into an MLS to name the complete MLS (N.J.A.C. 11:5-6.2(e)). The listing broker then has to notify the MLS of the listing within 48 hours of its effective date (N.J.A.C. 11:5-6.4(f)1i).

Each MLS adds its own rules. Garden State MLS, as one example (GSMLS Rules, §§2.7, 2.11):

• requires all listings of one-to-four-unit residential property and vacant land in its service area to be submitted,
• requires entry within 48 hours of the listing's effective date, and
• has a "Coming Soon" status for sellers who want showings delayed for a set time.

Other MLSs set their own deadlines and statuses, so learn your office's MLS rulebook. For the listing contracts themselves, see types of listing agreements.

What does "broker cooperation" mean in NJ?

It's the idea that makes an MLS work. Unless an owner directs otherwise in writing, every NJ licensee must fully cooperate with all other New Jersey licensees. For listing brokers, that includes (N.J.A.C. 11:5-6.4(f)):

1. notifying the MLS within 48 hours,
2. getting written offers from other firms to the seller within 24 hours, and
3. not putting unreasonable restrictions on showings to buyers working with other firms (requiring appointments through the listing office is allowed).

A seller can opt out, but only in writing. If the seller wants no cooperation at all, they sign a Waiver of Broker Cooperation in the wording the rule prescribes (N.J.A.C. 11:5-6.4(f)4). GSMLS still has the listing entered, with the signed waiver, as an "office exclusive" that only the listing side can see (GSMLS Rules, §2.7.3).

Does the MLS set commissions?

No. For one-to-four-family listings, New Jersey requires this notice in larger print: "No fee, commission or other consideration has been fixed by any governmental authority or by any trade association or multiple listing service" (N.J.A.C. 11:5-6.2(c)). GSMLS's rules say it won't "fix, control, recommend, suggest, or maintain commission rates," and it doesn't publish offers of compensation to other brokers in the MLS (GSMLS Rules, §§2.19, 6.1).

What do MLS statuses mean during a NJ sale?

Statuses track the deal, and they line up with New Jersey's attorney review rules. Under GSMLS's definitions (GSMLS Rules, §1.13):

State advertising rules match that timeline, and they count MLS notices as advertising. You can't call a property "sold" until closing, and once the contract is out of attorney review, ads must say "under contract" (N.J.A.C. 11:5-6.1(o)). Our attorney review guide explains the three-day period.

How do new agents get MLS access?

Through their broker. Garden State MLS's setup is typical (GSMLS Applications; GSMLS Rules, §§1.3–1.4):

• Members must be licensed to sell real estate in NJ (or be state-certified appraisers).
• The office's supervising broker joins as the Participant and is responsible for the office's users.
• Each licensee in that office joins as a Subscriber and pays the MLS's fees.
• Your employing broker must be a member before your agent application can be processed.
• GSMLS doesn't count referral agents as licensees for its membership.

Fees, keybox access and training vary by MLS, so ask brokerages about them.

How do MLS listings end up on public websites?

Through the listing agreement. A NJ licensee normally needs the listing broker's written consent to advertise another broker's exclusive listing. For internet listings, consent counts as given when the listing agreement authorizes posting on the broker's site, an MLS's site or a site the broker or MLS sends listings to, and that first site hasn't blocked others from linking to it (N.J.A.C. 11:5-6.1(n)).

The MLS's sold and off-market records also feed the comparable sales agents use for pricing. See CMA vs. appraisal.

Frequently Asked Questions

Can a buyer or seller join the MLS?

Not at GSMLS. Membership requires a NJ real estate license or a state appraiser certification (GSMLS Applications).

Can a seller keep a NJ home off the MLS?

Yes, but only in writing. An owner can relieve the listing broker of cooperation requirements in a signed writing attached to the listing, and an owner who wants no cooperation at all signs a Waiver of Broker Cooperation (N.J.A.C. 11:5-6.4(f)2, (f)4). Each MLS has its own procedure for these listings.

Is a home in attorney review still "active" on the MLS?

On GSMLS, yes. A listing under a signed contract still in attorney review stays active and available to show, and brokers may mark it "ARIP" (GSMLS Rules, §1.13).

Who is responsible for how an agent uses the MLS?

The broker. At GSMLS, the Participant is the broker or broker-salesperson who supervises the office, and is responsible for the payments and actions of the Subscribers in that office (GSMLS Rules, §1.3).

How fast does the MLS have to be updated?

NJ rules require the listing broker to notify the MLS of a new listing within 48 hours (N.J.A.C. 11:5-6.4(f)). GSMLS also requires status changes and closed sales to be updated within 48 hours (GSMLS Rules, §3.5).
