Every year without fail, we start getting calls in late October from business owners who want a vestibule up by November 1st. Sometimes even earlier — the first cold snap hits and suddenly everyone remembers they meant to call us in September.
Here’s the reality: November 15th is the date the NYC Building Code allows temporary storm enclosures to go up. Not November 1st. Not October 31st. November 15th.
And April 15th is the date they have to come down. Not “sometime in spring.” April 15th.
If you work around those two dates — and plan ahead for them — a vestibule runs smoothly year after year. If you don’t, you’re either rushing to get one up after the cold has already set in, or you’re getting a complaint from the DOB because your enclosure is still standing in May.
Why the Dates Exist
NYC Building Code Section 3202.3.2 permits temporary storm enclosures during the period between November 15th and the following April 15th. That’s five months — essentially the cold weather season in New York.
The reasoning is straightforward: these are seasonal structures, not permanent ones. The code allows them precisely because they’re temporary. The moment you start treating them like a permanent fixture — leaving them up past April 15th, skipping removal seasons — you’ve moved into different legal territory. At that point you either need a proper permit for a permanent structure, or you’re out of compliance.
Neither is where you want to be.
What Happens If You Leave It Up Too Long
We’ve seen it. A business owner goes through the fall and winter with their vestibule up, spring comes, things get busy, and suddenly it’s June and the structure is still there.
The DOB can issue a violation. A neighboring business or a passerby can file a complaint — and those get acted on. In a worst case, you’re looking at a stop-work order on any open DOB filings you have, or the cost of emergency removal on someone else’s schedule instead of your own.
The simpler version: just take it down by April 15th. We can handle the removal for you — that’s part of the service.
Plan Around the Dates, Not Toward Them
This is the part most people miss.
November 15th is when the vestibule is allowed to go up. That doesn’t mean November 15th is when you should start thinking about it.
If you want a vestibule installed on or shortly after November 15th, here’s what the realistic timeline looks like:
September: This is when the conversation should start. If you need a new vestibule fabricated, we need to measure the entrance, produce the design, order materials, and fabricate the unit. That process takes 1–2 weeks from deposit, but in October our schedule fills up fast. Starting in September means you’re at the front of the line.
October: If you’re returning to us from a prior season and just need reinstallation of your existing vestibule, October is fine. We schedule seasonal reinstallations throughout October and early November, with installations happening on and after the 15th.
November 1–14: We can take measurements and finalize designs during this window, but fabrication is typically already fully booked by now. If you’re calling us for the first time in early November, we’ll do what we can — but we can’t guarantee a November 15th installation.
November 15th onward: First day installations are possible and we do them, but they’re for customers who planned ahead. Walk-in November calls are the ones that end up waiting.
The April 15th Side of Things
Removal gets less attention than installation, but it matters just as much.
April 15th is the hard deadline. We recommend scheduling removal for the first or second week of April — not because the code requires it by then, but because life gets in the way. A restaurant that’s suddenly slammed with spring reservations, a retail owner dealing with a shipment — things come up. If removal is already on the calendar in early April, it happens. If it’s not, April 15th can sneak up.
We also offer storage between seasons. If you don’t have a back room or basement space for the frame and panels, we can hold the vestibule and bring it back the following November. It keeps the system intact, protects the Sunbrella fabric and polycarbonate panels from damage, and means you’re not scrambling for storage space every spring.
If You Missed the Window
Sometimes it happens. The season started, you didn’t get a vestibule in, and now it’s December.
You’re not out of options. We do late-season installations — it’s not ideal, but a vestibule that goes up December 1st still gives you four and a half months of protection through winter. Better than nothing, and in a New York winter, February and March are no joke.
Call us. We’ll tell you honestly whether we can fit it in and what the timeline looks like.
The Short Version
- November 15th: First day a temporary vestibule can legally go up in NYC
- April 15th: Last day it can legally stay up — must be fully removed
- Start the conversation in September if you want a new vestibule fabricated and installed on schedule
- October is fine for returning customers scheduling reinstallation
- Don’t wait until November — by then the schedule is tight and the cold has already arrived
If you need to get on the schedule for this season, reach out now. The earlier you call, the more options you have.
