Governor Ned Lamont signed Connecticut's SB 340, enacted as Public Act 26-23, on May 27, 2026. It took effect October 1, 2026. For one-to-four-unit residential property, public marketing is the default, and a seller can opt out by signing a state form. This page describes what the act requires and where a record of the seller's decision fits alongside the required form.
Updated October 17, 2026
The short version. Since October 1, 2026, an agent or broker representing a seller or landlord of one-to-four-unit residential property must make the property available to the general public, concurrently with or before the first instance of public marketing, unless the seller signs the Seller/Landlord Opt-Out of Real Estate Public Marketing form. The act does not ban private listings. The opt-out form records that the seller chose not to market publicly; a documented listing decision records what the seller was shown and chose, and the seller signs both. The Listing Strategy Decision Record (LSDR) is one tool built to produce one.
The act requires an agent or broker representing a seller or landlord of residential property with one to four units to make the property available to the general public on a fair, nondiscriminatory, publicly accessible listing platform reasonably designed to generate broad public exposure. The timing is concurrently with, or prior to, the first instance of public marketing. The exception is a seller or landlord who signs the state's opt-out form.
Reporting on the act describes several examples: displaying the listing on the internet or social media, emailing it to more than one recipient at a time, using lawn signs, flyers, or digital ads that carry the broker's information, and inclusion on a private network among two or more brokerages or franchisees. The last example matters for brokerages that rely on shared or affiliated private networks. Whether a particular practice or network arrangement triggers the requirement depends on the statutory text, so review it with counsel.
The opt-out is the seller's or landlord's signed Seller/Landlord Opt-Out of Real Estate Public Marketing form. Reporting indicates the act itself includes the required language for the form, which describes the potential consequences of forgoing public marketing, such as a lower sale price or a longer time on the market. Reporting also describes a narrower exception for a bona fide safety or similar need. Confirm the form and the exception against the statute, and note that a record of a seller's stated concern is not a finding that an exception applies.
SB 340 gives a Connecticut seller a choice at the start of the listing: public marketing, or a signed opt-out. The form records that the seller opted out. A documented listing decision records what the seller was shown, what mattered to the seller, the tradeoffs between those priorities, the seller's stated reason, and what the seller chose, with a defined fallback trigger where marketing is restricted and the signatures of the seller, the listing agent, and the broker. It applies equally where the seller chooses public marketing.
Where the LSDR fits
The LSDR is one tool built to produce a documented listing decision. It records the decision only; execution and outcomes are documented separately. It complements the state opt-out form, does not replace it, and is not legal advice. It does not tell you whether a given practice satisfies SB 340. It is published by LTC Capital, LLC, which shares common ownership with The Cyr Team.
This page does not summarize the penalties for violations or how the act applies to listing agreements signed before the effective date. Confirm both in the statute and with counsel.
Connecticut, Wisconsin, and New York use an opt-out model. Washington uses a prohibition model with a health-or-safety exception. Connecticut's requirement is keyed to the first instance of public marketing; Wisconsin's runs from the start of the agency agreement. The state-by-state reference compares all four.
When does Connecticut's SB 340 take effect?

What does SB 340 require?
For residential property of one to four units, an agent or broker representing a seller or landlord must make the property available to the general public, concurrently with or before the first instance of public marketing, on a fair, nondiscriminatory, publicly accessible listing platform reasonably designed to generate broad public exposure. The exception is where the seller or landlord signs the Seller/Landlord Opt-Out of Real Estate Public Marketing form. The act does not ban private listings.
What counts as the first instance of public marketing?
Reporting on the act lists examples: displaying the listing on the internet or social media, emailing it to more than one recipient at a time, using lawn signs, flyers, or digital ads with the broker's information, and inclusion on a private network among two or more brokerages or franchisees. Whether a particular practice or network arrangement triggers the requirement depends on the statutory text, so review it with counsel.
How does the opt-out form work?
The seller or landlord signs the Seller/Landlord Opt-Out of Real Estate Public Marketing form. Reporting indicates that the act itself includes the required language for the form, which describes potential consequences of forgoing public marketing, such as a lower sale price or a longer time on the market. Reporting also describes a narrower exception for a bona fide safety or similar need. Confirm the form and the exception against the statute.
What about listings signed before October 1, 2026, and what are the penalties?
Whether and how the act applies to existing listing agreements, and the penalties and enforcement procedures for violations, are questions for the statute and counsel. This page does not summarize them.
Where does the Listing Strategy Decision Record fit?
The opt-out form records that the seller chose not to market publicly. A documented listing decision records what the seller was shown, what mattered to the seller, and what the seller chose, and the seller signs both. The Listing Strategy Decision Record (LSDR) is one tool built to produce one. It records the decision only, complements the required form and does not replace it, and is not legal advice.
The LSDR is licensed per agent and configured to your brokerage, your MLS, and your stated practices. It pairs with whichever state-required form applies to your seller.
