what is the REBNY RLS?
Back to the NYC Real Estate Blog
The REBNY RLS is the Residential Listing Service, New York City’s system for sharing home listings between brokerage firms. It’s run by the Real Estate Board of New York, a private trade association, not as a Realtor MLS. Firms that join agree to cooperate under the Universal Co-Brokerage Agreement, which has been revised six times since October 2023.
We participate in the RLS and pull its listings into our own site. So this is the system from the inside, including the parts that changed in the last three years.
The short version: a listing system run by a club, not a government.
| REBNY RLS | A typical Realtor MLS | |
|---|---|---|
| Run by | REBNY, a trade association | A local Realtor board or its subsidiary |
| Rulebook | The Universal Co-Brokerage Agreement | NAR policy plus local MLS rules |
| Coverage | The five boroughs of NYC | A county or metro region |
| Public search site | Citysnap | Varies; often the board’s own portal |
What is the REBNY RLS?
REBNY says it “allows for the sharing of exclusive listings among all REBNY brokerage firms that are members of REBNY’s Residential Brokerage Division.” In practice, a firm submits its exclusive listings, and every other member firm can show them and co-broker them.
By REBNY’s own numbers, the RLS carries roughly 70,000 listings a year, worth about $75 billion. It spans 500-plus member firms and gets around 90 million views a month.
You don’t automatically get RLS access by joining REBNY. A firm can also join the RLS separately, sign the agreement, and pay its own fees.
RLS vs a Realtor MLS: Is the RLS a real MLS?
Functionally, yes; structurally, no. Same job, different letterhead, and no Realtor board in sight. It does what an MLS does: pools listings, sets cooperation rules, and shares data feeds.
But REBNY is a private trade association founded in 1896, with more than 14,000 members. It isn’t a National Association of Realtors board, and the RLS isn’t a Realtor MLS of record. The rulebook is the UCBA, enforced by REBNY through its own arbitration and penalties.
That distinction mattered in court. In August 2026, the Eighth Circuit held that REBNY-based commission claims and NAR-based claims “hinged on the same operative factual predicate,” so the national settlement reaches New York.
The UCBA and how it’s changed since 2023
Six revisions in three years, which is a lot for a document nobody reads for fun.
- October 2023: REBNY announces it will decouple commissions.
- January 1, 2024: decoupling takes effect. The buy-side compensation offer must come from the seller.
- August 2024: RLS compensation fields become optional.
- January 13, 2025: Written buyer agency agreements become mandatory before showings.
- February 2025: a full UCBA rewrite removes references to co-brokering compensation.
- August 1, 2025: All compensation fields are removed from the RLS entirely.
- 2026: days-on-market resets after 30 days withdrawn, plus an offer-verification requirement.
REBNY’s decoupling came about five months before the NAR settlement and was legally its own move. It later explicitly aligned the August 2025 field removal with the settlement. This page is part of our guide to NYC commissions and rebates.
Why do NYC listings behave differently online?
The RLS is why your friend’s apartment vanished from one website but not another. NYC has never had a single public MLS site like other markets do.
StreetEasy, owned by Zillow, has never accepted the RLS feed and takes only direct brokerage feeds. In 2017, it started charging agents per rental listing, and about ten top firms pulled their listings in response. REBNY launched a public portal with Homesnap in 2021, then Citysnap with CoStar in June 2022, and ended its Realtor.com syndication that August.
In 2026, the fight moved again, with Compass pushing listings off StreetEasy and StreetEasy restricting agent access in return.
What does the RLS mean for your commission?
The listing used to state what agents’d be paid; now it says nothing. Since August 1, 2025, an RLS listing no longer includes a buy-side compensation figure, and agents can’t sort listings by what they pay.
The money still flows the same way. On a resale, the seller funds both brokers; the buyer’s broker is paid at closing, and the split is negotiated. Our page on co-broking covers the mechanics, and what NestApple returns to buyers covers the rebate. Run a real deal in our closing-cost calculators.
What we see on our own deals
The feed is plumbing, and plumbing is only interesting when it leaks. Most of the time, the RLS just works: a listing appears, we show it, we co-broke it.
The friction shows up at the edges:
- A non-REBNY seller’s agent who never joined the RLS
- A listing that’s on Citysnap but not StreetEasy
- A buyer who assumes StreetEasy is the whole market
Knowing that the RLS exists is usually enough to explain the gap.
Common questions
Is the REBNY RLS an MLS? It performs the same job: pooling listings and setting cooperation rules. But it’s run by a trade association rather than a Realtor board, so it isn’t a Realtor MLS. Its rulebook is the Universal Co-Brokerage Agreement.
Why isn’t an NYC listing on StreetEasy? StreetEasy doesn’t accept the RLS feed and takes only direct brokerage feeds. A listing can be on the RLS and Citysnap without being on StreetEasy.
What did the 2024 UCBA change do? It decoupled commissions. As of January 1, 2024, the buy-side compensation offer must come directly from the seller, not through the listing broker.
Does the RLS still show buyer-agent commissions? No. All compensation fields were removed from the RLS on August 1, 2025, to match the NAR settlement terms.
