Chelsea vs Union Square: Office Space Compared

The rent gap, and what the premium actually buys

Two medians sit far enough apart that no amount of negotiating closes them: $56 per square foot per year in Chelsea against $88 in Union Square, a difference of about $32 a foot, or roughly 36% off the Union Square number. Against the $75 citywide median across our book, Chelsea runs about 25% below the city and Union Square about 17% above it. On a 5,000 square foot floor that spread is roughly $160,000 a year.

The premium pays for convergence and for scarcity rather than for better buildings. Union Square's stock is boutique prewar just north of the park, park light and single-tenant floors, and there is very little of it; Chelsea's is the loft corridor in the mid-20s, garment-era buildings with open, high-ceilinged floors, and there is far more.

Read the ranges too. Chelsea asks $44-$64 and Union Square asks $60-$115, so its cheapest floor, 29 West 17th Street at $60, prices inside Chelsea's own band while 900 Broadway at $115 asks nearly double Chelsea's top. And 836 Broadway publishes no asking rent, which leaves the Union Square median resting on two priced floors.

What we hold in each, and which teams fit

Our book holds 9 floors in Chelsea and 3 in Union Square. Chelsea spans 2,937 to 18,668 square feet, roughly 17 to 107 desks at the 175 square feet per person we plan to; Union Square spans 2,500 to 13,754 square feet, roughly 14 to 79 desks.

• Chelsea, 9 floors: two just under 3,000 square feet, one at 3,500, four between 7,000 and 9,500, two above 17,600.
• Union Square, 3 floors: one at 2,500 square feet, one at 4,000, one at 13,754, nothing in between.

That hole in the middle of the Union Square book is where most of our clients live. A team of 40 wanting 7,000 to 9,000 square feet can walk four Chelsea floors this week and nothing at all in Union Square, and anything above roughly 80 desks is out of the submarket entirely. The small end runs the other way, down to 2,500 square feet against Chelsea's 2,937.

Getting there, and getting your people there

Chelsea's lines are A/C/E, 1, F/M at 14th and 23rd. Union Square's are 4/5/6, N/Q/R/W, L all at 14th Street.

Union Square is the widest transit catchment below 42nd Street, which keeps Brooklyn's engineering talent close and puts most of the city inside a forty-minute door-to-door trip, and that reach is the honest justification for the premium. Chelsea covers the west side, stops at both 14th and 23rd, and puts a large share of Brooklyn, Queens and New Jersey commutes within one seat.

Commute geography belongs in the hiring plan rather than the amenities list. Recruiting senior engineers who already live along the L, an address at 14th Street removes an objection you would otherwise answer with money for the length of the lease. Hiring nationally with two or three office days, that advantage thins fast. Map where your team sleeps before you tour.

Our recommendation, by type of tenant

Teams between roughly 35 and 110 people should take Chelsea, and we do not think it is close. A 15,000 square foot requirement carries about $480,000 a year of difference, and those dollars do more in buildout than the extra subway lines will. Nine floors also let us run a real process against three.

Small senior teams should pay the Union Square premium, and this is the case we make against our own cost-cutting instincts. On 2,500 square feet the same spread is about $80,000 a year, roughly one junior hire, and for a twenty-person company whose founders fight for every recruit, the address earns that back. The premium scales with footprint, so a small company can afford conviction here and a large one cannot.

Studio, media and design teams that want open loft floors belong in Chelsea, which is what the corridor is made of. Anyone above 80 desks is decided by arithmetic rather than taste. A price-sensitive team under 25 desks should still see 29 West 17th Street, which asks like a Chelsea floor on the Union Square lines.

How to settle this in one afternoon

Both submarkets can be toured in a single afternoon and should be, since reading two medians is not the same as standing on the floors. We hold space in each, so it is one call, and we would start in Union Square while there is something to see.

Bring a 24-month headcount plan rather than today's number, and ask how much of the rentable area is actually usable, because loss factor varies building to building and a cheap floor carrying a heavy one is not cheap. Ask how the escalation is written, whether electric is submetered, and whether the landlord wants a letter of credit or a good guy guarantee, since those land very differently on a young balance sheet.

Face rent only opens that conversation; free rent and the improvement allowance decide what you actually pay. We test fit the one or two floors that survive, then negotiate. Buildout keeps its own calendar, so work backward from a hard move-in date.
