Joseph Ranola is a real estate broker and not an attorney or a surveyor. Whether a street is mapped, who owns the roadbed and what a certificate of occupancy requires are questions for your attorney and a licensed surveyor, and this page explains what to ask.

What is the difference between a mapped street, an unmapped street and a private road in NYC?

Under the NYC Zoning Resolution, a “street” is mainly a way established on the City Map, and a “private road” is a right-of-way that is not a street. In most districts a private road gives vehicular access from a street to five or more dwelling units in buildings wholly beyond 50 feet of a street line. In Staten Island’s lower density growth management areas the test is lower: three or more buildings beyond 50 feet. Source: ZR 12-10 at zr.planning.nyc.gov.

Mapped status is a separate state-law question under General City Law § 36, which asks whether a street is on the official map before a certificate of occupancy can issue for a new building.

Can a new house on an unmapped street get a certificate of occupancy in NYC?

Often only with extra approvals. General City Law § 36 generally requires the street to be on the official map, and the Board of Standards and Appeals can grant relief. For one- and two-family homes, subdivision 3 lets the Department of Buildings skip BSA review in two situations: when the way has been open and in use for at least ten years, or when the home is on the same block and street as a building the BSA already approved. In both cases the street must be improved to Department of Transportation standards and the home needs an automatic sprinkler system. Source: nysenate.gov, GCT § 36.

Joseph Ranola asks your attorney to confirm the text before you rely on this summary. The BSA denied a proposal for 163 buildings on 34-foot unmapped private streets in Staten Island in 2020 (BSA Cal. 2017-107-A), so approval is not automatic.

If you are buying on a private road in Staten Island, here is what is different

Staten Island’s R1, R2, R3, R4A, R4-1 and C3A land is a lower density growth management area, and private roads there fall under ZR 26-30 through 26-33. Those sections require street lighting, signage and crosswalks that meet DOT standards, entrances at least 50 feet from an intersection, and an 8-foot landscaped screening strip. ZR 26-34 lets the City Planning Commission modify or waive those requirements everywhere except Staten Island, so a Staten Island road cannot be relaxed that way. Source: zr.planning.nyc.gov.

Both Board of Standards and Appeals cases reviewed for this page involved Staten Island sites, though no official count of private streets by borough was found.

If you are buying on a private road in Brooklyn, here is what is different

Brooklyn has no lower density growth management area, so private roads in R3, R4 and R5 districts fall under ZR 26-20 through 26-27. The road must be a paved bed built to DOT standards with curbs, at least 38 feet wide or 34 feet when enough parking sits off the roadbed. The City Planning Commission may authorize modifications under ZR 26-26, but never below 34 feet. Lots that are entirely single-family detached homes, and private roads that existed on February 6, 2002, are exempt. Source: zr.planning.nyc.gov.

No comparable Brooklyn BSA case was found, and this page does not claim Brooklyn has none.

Who plows, repairs and maintains a private street in NYC?

Not the city, at least for snow. NYC311 states that the Department of Sanitation does not clear private streets and that snow on them cannot be reported through 311. A 2004 BSA approval for a Staten Island site required a homeowners association to maintain the roadway, drains, lighting and snow removal, which shows one common arrangement. The zoning sections above set design standards and say nothing on who maintains the road. Source: portal.311.nyc.gov, KA-02296.

The New York State Property Condition Disclosure Statement does not ask whether the street is public or private, so Joseph Ranola tells buyers to ask directly and to request any road maintenance agreement before closing.
