Street Signals  //  The Corridor  //  Week 01  //  September 8, 2026

West Harlem came back blank.

The city walked every storefront in New York this spring. Central Harlem got a number and East Harlem got a number. The district printing the highest rent of the three did not.

01
Status
Central Harlem storefronts run 15.2% empty. East Harlem runs 16.9%. West Harlem has no published number. The Comptroller walked all 142,000 storefronts in the city this spring and the three tabulation areas that make up CD9 cleared no threshold that got them named.
02
Why
The demand curve is set by institutions that never sign a lease. The academic year runs late August to mid-December, then late January to mid-May. CD9 carries 6.1% residential vacancy against 4.0% in East Harlem and 5.6% for the borough. The district with the most institutional gravity carries the most slack in Manhattan.
03
Trend
Empty here is slow, not permanent. Harlem clears the Comptroller three-quarter persistence band and falls out of the eight-quarter band that holds the Upper East Side, Upper West Side, Midtown, Washington Heights and Inwood. Storefronts refill. They take about nine months. In CD9 that is one academic year.
04
Leases
No public asking-rent series covers this corridor. REBNY tracks 16 Manhattan corridors and none of them is up here. JLL prices prime Manhattan at $585 a foot off Fifth Avenue, SoHo and Times Square. If you are comping Broadway at 137th against either one, you are comping against a different city.
05
Permits
We pulled the city food-service file this morning. 320 active establishments across the CD9 zips, 26 permitted and not yet inspected, which is the state a restaurant sits in before the door opens. That is an 8.1% pipeline against 13.3% for Manhattan. Ground-floor construction permits in CD9 run 145 year to date against 257 in the same window last year, down 43.6% where the borough is down 50.8%. Buildings are being worked on at the borough pace. Operators are queuing behind them at two thirds of it.

Zip approximation: 10027 and 10031 for CD9. 10027 carries part of Central Harlem, which understates CD10.
06
Closings
The city file carries active permits only, so an establishment dropping out of it is a closure signal before anyone reports it. Baseline set today: 320 active across 10027 and 10031. From next Tuesday this line carries the count that went dark and the streets they sat on.
07
The opening
Amsterdam and Broadway hold the largest share of what is permitted and not yet open, and two of the filings are campus food service. A first national chain entry is in the queue on St Nicholas. Ground floor here priced against an eight-month revenue year is the cheapest institutional foot traffic in Manhattan. Priced against twelve, it is the reason the last operator left in July.
The move
Do. If you hold paper between 125th and 155th, pull your tenant DOHMH status monthly. It moves before the rent does.
Watch. September and October operator changes. Turnover on this corridor does not present as vacancy.
Versus the city. Citywide storefront vacancy is 11.0% and Manhattan is 12.9%. Both Harlems that have a number sit above both. The one with no number prints the highest rent of the three.
