Updated August 25, 2026.<\/strong> New York City apartment-building owners and property managers need to understand how intercom, entrance-door and door-release requirements apply to their properties. New York Multiple Dwelling Law \u00a7 50-a and New York City Department of Buildings rules establish requirements for certain Class A multiple dwellings, including two-way voice communication and the ability for an apartment occupant to release the main entrance locking mechanism.<\/p>\n\n\n\n

The exact requirements can depend on the building\u2019s residential classification, number of apartments and when the building was erected or converted to residential use. This guide explains the key rules, common compliance questions and practical steps owners and managers can use when evaluating an intercom system.<\/p>\n\n\n\n

What Does the NYC Intercom Law Require?<\/h2>\n\n\n\n

For a Class A multiple dwelling erected or converted after January 1, 1968 with eight or more apartments<\/strong>, New York Multiple Dwelling Law \u00a7 50-a requires an intercommunication system at the automatic self-locking entrance door that provides public access to the building\u2019s main entrance hall or lobby.<\/p>\n\n\n\n

The required system must support two core functions: voice communication<\/strong> between the occupant of each apartment and a person outside the required entrance door, and remote door release<\/strong> so the apartment occupant can release the entrance locking mechanism from the apartment.<\/p>\n\n\n\n

Which NYC Apartment Buildings Need an Intercom?<\/h2>\n\n\n\n

Buildings Erected or Converted After January 1, 1968<\/h3>\n\n\n\n

A Class A multiple dwelling erected or converted after January 1, 1968 and containing eight or more apartments<\/strong> is specifically covered by the statutory intercommunication-system requirement.<\/p>\n\n\n\n

Buildings Erected or Converted Before January 1, 1968<\/h3>\n\n\n\n

Older buildings are treated differently. For qualifying Class A multiple dwellings erected or converted before January 1, 1968, the statute includes a provision under which installation of the specified self-locking doors and intercommunication system is required when tenants occupying a majority of the apartments request or consent to the installation in writing<\/strong>.<\/p>\n\n\n\n

Owners of older New York City apartment buildings should therefore avoid assuming that the same rule applies identically to every property. Building age, occupancy classification, apartment count and the property\u2019s history should be reviewed when determining the applicable requirements.<\/p>\n\n\n\n

What Must a NYC Apartment Intercom System Do?<\/h2>\n\n\n\n

A building intercom covered by these requirements is more than a simple entrance doorbell. The system should support communication between residents and visitors and work together with the entrance locking equipment.<\/p>\n\n\n\n

Two-way voice communication:<\/strong> residents must be able to communicate with someone outside the required building entrance.<\/p>\n\n\n\n

Door-release capability:<\/strong> the apartment occupant must be able to activate the mechanism that releases the applicable entrance-door lock.<\/p>\n\n\n\n

Proper equipment location and access:<\/strong> applicable entrance and apartment equipment must be installed in accordance with the governing rules and remain accessible for its intended use.<\/p>\n\n\n\n

Working entrance hardware:<\/strong> a functioning intercom does not correct a failed electric strike, relay, power supply, door closer or locking mechanism. The entire controlled-entry system should operate correctly.<\/p>\n\n\n\n

New York City Department of Buildings rules also address entrance-door locks, intercommunication equipment and equipment location. See 1 RCNY \u00a7 42-01<\/a>.<\/p>\n\n\n\n
