Summary
New York City requires automatic sprinklers throughout new Group R (residential) buildings under the Building Code, but detached one- and two-family homes and townhouses up to three stories with separate egress are exempt.
An automatic sprinkler system shall be installed in Group R fire areas. An automatic sprinkler system shall be installed throughout buildings with a main use or dominant occupancy of Group R. Exception: An automatic sprinkler system shall not be required in detached one- and two-family dwellings and multiple single-family dwellings (town houses), provided that such structures are not more than three stories above grade plane in height and have separate means of egress.
Full Breakdown
Under NYC Building Code Section BC 903.2.8, any new building whose main or dominant use is Group R (residential) must have an automatic sprinkler system installed throughout, and every individual Group R fire area needs sprinkler coverage on its own. The Department of Buildings enforces this at plan review and construction inspection under Title 28 of the Administrative Code, which incorporates the Building Code citywide. The one carve-out: detached one- and two-family dwellings and townhouse-style multiple single-family dwellings skip the mandate if they are no taller than three stories above grade plane and each unit has its own separate means of egress.
Violations & Fines
Occupying or completing a covered Group R building without an approved sprinkler system blocks the certificate of occupancy; DOB can issue stop-work orders and violations until an approved system is installed and passes inspection.
