Walk Up Apartment Buildings

Among the building types that bear on the work of Richard Joseph Spinelli, whose company Sandhills Real Estate renovates houses, apartments and townhouses on and around Belmont Avenue, Lorillard Place and Bathgate Avenue, the walk up is defined less by a style than by a missing machine. A walk up apartment is a home above the ground floor of a building that has no elevator, so the only way in is by the stairs. In New York the type owes its persistence to a single clause of the 1929 Multiple Dwelling Law, which demanded passenger elevators in new buildings taller than six stories or sixty feet and said nothing about anything shorter.¹

The six story rule

Section 51 of the state law covers shafts, elevators and dumbwaiters. Its sixth subdivision holds that every dwelling erected after April 18, 1929 that exceeds six stories or sixty feet in height must have one or more passenger elevators, working at all times, with at least one reaching every apartment above the entrance story.¹ The same section sets out fireproof enclosures for new shafts, interlocks that stop a car from moving while a hoistway door is open, and a cap of three elevators in any one shaft.¹

What the rule left alone

The threshold drew a clear line. A new building of six stories or fewer could still be built with stairs alone, and every building finished before the 1929 date was untouched by the elevator mandate. A related provision reinforces the same ceiling. Under Article 5, a new multiple dwelling of six stories or less and no more than seventy five feet above the curb may be of non fireproof construction.¹ Six stories thus marked the point at which both the lift and the heavier fireproof frame became requirements, and below it the older, simpler way of building carried on.

Walk ups before the rule

The tenement had already made climbing normal. The earliest purpose built tenements, from the 1830s, stood on the narrow 25 by 100 foot lots laid out in the Commissioners’ Plan of 1811, reached up to five stories, and took light only at the front and back.² Later tenements went higher without adding lifts. Village Preservation describes a group of six story dumbbell tenements on First Avenue from 1898 and a six story tenement with stores from 1907, neither with any mention of a lift.² A Tenement Museum post describes a six story dumbbell building on Ludlow Street whose narrow, dark stairs and landing windows onto an air shaft still serve its tenants.⁵ The law of 1929 did not create the walk up. It fixed the height at which the walk up had to end.

How the survey counts a walk up

The city’s Housing and Vacancy Survey uses three measures of access: whether a home can be reached from the sidewalk without any steps, whether the building has an elevator, and whether reaching the home means climbing one or more flights of stairs.³ The third measure is the survey’s walk up count. It covers homes on the second floor or higher where no elevator is present, and it draws on property records, the interviewer’s own observation and what residents report.³

The survey’s glossary treats an elevator as present if it exists, whether or not it runs, and leaves out freight lifts. Elevator figures are tabulated for homes in buildings of two or more stories.⁴

The citywide picture

In 2023, 1,699,000 homes, or 46 percent of the city’s stock, were in buildings with an elevator. Some 873,500, or 24 percent, required climbing at least one flight to reach the door. A further 1,256,000, or 34 percent, could be reached from the sidewalk with no steps at all.³ The survey estimated that walk up homes fell by about 42,000 between 2021 and 2023, a change it judged not statistically meaningful.³ Demand for the type has held up: The New York Times reported in 2013 that sales of walk up apartments had jumped over the prior year, and that one Brooklyn developer chose three story walk ups over a taller elevator building.⁶

Size decides

Building size explains most of the pattern. Where a building holds between three and five homes, 51 percent of homes need stairs and only 2 percent have an elevator. In buildings of six to 19 homes, 59 percent need stairs and 14 percent have an elevator. Houses of one or two homes show 1 percent with an elevator and 23 percent reached by a flight or more. Once a building holds 20 to 49 homes, the elevator share rises to 55 percent.³ The small apartment house and the two family house are the core of the walk up stock. Urban Omnibus reported in 2016 that about 40 percent of the city’s households live in buildings with fewer than five units.⁷

Age decides too

The elevator rule shows up in the age data. Among homes in buildings finished before 1947, only 30 percent have an elevator and 33 percent are reached by stairs. For homes built from 1947 to 1973, 66 percent have an elevator and just 11 percent need a climb.³ Brick Underground observed in 2019 that most walk ups were built before the Second World War and are usually heated by steam, and that the stairs become a real obstacle after an injury.⁸ The contrast fits the timing of the rule, which applied to everything built after 1929 and to none of the prewar buildings finished earlier. The stair bound homes of the older stock include the tenements and small apartment houses that predate or sit below the 1929 threshold, and the law behind that threshold is described under the Multiple Dwelling Law.

Borough by borough

Manhattan is the most elevator served borough, with 77 percent of homes in a building with a lift and 17 percent reached by a flight or more. The Bronx follows, with 54 percent served by an elevator, 21 percent requiring stairs and 38 percent reachable from the sidewalk without a single step. Brooklyn has 34 percent with an elevator and 33 percent up at least one flight. Staten Island, a borough of smaller buildings, has the lowest elevator share at 10 percent and also the lowest share reached by stairs, likewise 10 percent.³

The stair the law does govern

A walk up lives or dies by its staircase, and the 1929 law is exact about stairs in buildings put up after its date. Treads must be at least nine and one half inches deep without the nosing, risers no more than seven and three quarter inches high, and every step in a flight uniform. The tread and riser in inches, multiplied together, must come to between seventy and seventy five. Winding stairs are barred in any multiple dwelling, and stairs wider than three feet eight inches need a handrail on each side.¹ Keeping those stairs sound in an older building is part of renovating older buildings.
