What Washington’s New Private Listing Law Means for Home Sellers
Washington recently passed a new law designed to increase transparency and ensure that homes marketed for sale are made broadly available to buyers and real estate brokers.
Senate Bill 6091, signed into law in March 2026 and taking effect in early June 2026, is often described as a ban on “private listing networks” or “pocket listings.” However, the law does not require every Washington homeowner to list their property in the Multiple Listing Service, or MLS.
Instead, it changes how brokers are permitted to market residential properties.
What Does the New Law Require?
Under the new law, when a real estate broker markets a residential property, the broker generally cannot limit that marketing to a select group of buyers, agents, or members of the broker’s own network.
If a property is being marketed, it must be made available to the general public and all other real estate brokers at the same time.
In practical terms, a brokerage cannot promote a home exclusively within its own private network while preventing other brokers and potential buyers from learning about the property.
The law does include an exception when limiting a property’s exposure is necessary because of a legitimate health or safety concern involving the seller.
What Does This Mean for Washington Home Sellers?
Home sellers still have options when deciding how their property should be marketed. However, brokerages must ensure that their marketing strategies comply with the new statewide requirements.
Marketing Strategies That Are Generally Allowed
Listing the property in the MLS using a traditional listing strategy
Using MLS-approved options that limit certain types of online exposure
Marketing the property to all brokers and potential buyers simultaneously
Restricting marketing when necessary to protect the seller’s health or safety
Marketing Strategies That Are Generally Not Allowed
A brokerage marketing a home exclusively within its own internal network
“Private Exclusive” programs that allow only selected agents or buyers to view a listing
Marketing a property to a limited group while intentionally excluding the broader market
Using an off-market network to restrict access to a home that is actively being promoted for sale
How Will the Law Affect NWMLS Sellers?
For many sellers in King, Pierce, Snohomish, and surrounding counties, the practical impact of the new law may be relatively limited.
Northwest Multiple Listing Service has historically maintained stricter cooperation and listing-marketing requirements than many MLS organizations throughout the country. NWMLS rules have generally required listings to be broadly available to participating brokers and have restricted public pre-marketing outside the MLS.
The new law extends a similar approach across Washington and prevents brokerages from using private networks to keep actively marketed homes away from the broader real estate market.
What Should Sellers Know Before Listing Their Homes?
Washington’s new law does not force every homeowner to place their property in the MLS. However, it does restrict a brokerage’s ability to market a home only to selected buyers or agents.
Once a property is marketed, it generally must be marketed openly and made available to all brokers and the public at the same time, unless a valid health or safety exception applies.
For sellers in Burien, Normandy Park, West Seattle, and surrounding communities, the biggest change affects brokerages that promote “private exclusive” listings or off-market networks. These strategies are now significantly more restricted under Washington law.
Before selecting a listing strategy, sellers should work with a knowledgeable local real estate professional who can explain the available marketing options and ensure that the property receives appropriate exposure while complying with current Washington law.
