Imposes a moratorium lasting up to 180 days on the consideration, approval, or authorization of licenses, permits, permitted uses, special uses, accessory uses, variances, development plans, occupancy permits, building permits, and similar approvals that would enable the establishment, construction, conversion, or commencement of a data center.

Defines covered data centers to include AI, enterprise, managed services, colocation, cloud, and edge data centers, as well as facilities exceeding 5,000 square feet that house servers, data storage, or network equipment.

Extends the moratorium to related accessory facilities and infrastructure located on the same site, including utilities, external mechanical equipment, water towers, and security facilities.

Suspends and tolls applicable review and decision deadlines for data-center applications during the moratorium, and prevents an application from being deemed approved because an official or city body fails to act within the usual period.

Allows the moratorium to be extended beyond 180 days by a majority vote of City Council if additional time is needed for the city’s study and recommendations, or repealed earlier by a majority vote.

Exempts repairs or replacements of existing data centers and data centers contained within existing businesses in Brooklyn.

The moratorium does not apply to repairs or replacements of existing data centers, or to data centers contained within existing businesses, allowing those facilities to continue operating and be upgraded.

The moratorium covers physical data-center facilities only when they exceed 5,000 square feet, so facilities at or below that size are outside the measure’s moratorium.
