How long does a New York City sidewalk shed permit last now?

Ninety days. Local Law 48 of 2025 cut the term from a year, and permits issued or renewed in 2026 no longer roll over automatically in DOB NOW. Each renewal has to be submitted by hand, carries a base fee reported at $130, and must include a written progress report from a Registered Design Professional describing what work has actually happened since the last permit. From the second renewal onward, a shed put up for facade or building repair cannot be renewed without paying a DOB penalty first. The practical effect is that an owner who used to let a shed sit now faces a decision four times a year.

Does a shed permit always mean facade repair work is coming?

No, and treating it that way will waste your time. Across the 13,112 New York City addresses that pulled a shed permit since January 2021, 3,704 later filed a facade or masonry repair permit at the same address. That is 28.2%. Sheds also go up for new construction, enlargements and demolition, and those uses are exempt from the shorter permit term entirely. The number is a base rate to work from, not a promise. It is also a floor rather than a ceiling, because we detect repair filings by keyword and some repair work is described in wording our match does not catch.

How far ahead of the repair permit does the shed go up?

The median gap in our file is 81 days. Half of the addresses that converted filed their repair permit inside that window and half took longer, and 2,224 of the 3,704 filed within 180 days. Boroughs differ more than you would expect. Queens runs fastest at a median of 55 days, Manhattan and Brooklyn sit near the citywide figure at 80 and 82.5 days, the Bronx runs to 94.5, and Staten Island stretches to 214 days on a small base of 119 addresses. If you sell into one borough, use that borough's number.

Which borough has the most shed activity?

Manhattan, by a wide margin. Of the 14,769 shed-referencing permits in the last twelve months, Manhattan accounts for 6,591, Brooklyn 4,413, the Bronx 2,005, Queens 1,672 and Staten Island 88. Manhattan also converts best, with 34.7% of its shed addresses since 2021 going on to file repair work, against 19.1% in Brooklyn. Staten Island barely registers, which fits a borough of mostly low-rise single-family housing where facade programs rarely apply.

Who actually erects the sheds?

A small set of firms. Only 312 distinct contractors filed the building-type shed permits in New York City over the last twelve months, and the contractor name is populated on every one of those records. That is a nameable account list rather than a lead list, and it is worth building. The shed erector knows a facade job is coming before the restoration contractor does, because the shed goes up first.

NYC Sidewalk Shed Permits: The 90-Day Repair Window

By the permits.llc team · Last reviewed August 18, 2026 · Optimal window: Weeks 1–12

TL;DR

NYC shed permits now run 90 days, and each renewal needs a progress report.
Our DOB file shows a median 81 days from shed permit to repair permit.
28.2% of shed addresses since 2021 later filed facade or masonry repair.
4,424 addresses have a shed since 2024 and no repair permit yet.

A New York City sidewalk shed permit is the earliest public signal that facade repair work is coming to a building. In our Department of Buildings file, 28.2% of the 13,112 addresses that pulled a shed permit since January 2021 went on to file a facade or masonry repair permit at the same address, and the median gap between the two filings was 81 days. Local Law 48 of 2025 cut the shed permit term to 90 days.

Those two numbers, 81 and 90, are the whole argument. The regulatory clock and the observed buying cycle are now almost exactly the same length.

Before 2026, a shed could go up under a one-year permit and renew more or less indefinitely, which is how New York ended up with sheds standing for a decade. That era is over. What it leaves behind, for anyone selling restoration, masonry, engineering or waste services, is a dated countdown that starts in public.

What does a sidewalk shed permit actually signal?

It signals that someone has been told the building envelope is a problem and has spent money to protect the sidewalk while they decide what to do about it.

Sheds go up for several reasons. New construction, enlargements and demolition all use them, and those uses are exempt from the shorter permit term. The ones that matter commercially are the sheds erected because a facade condition was found, usually through the Facade Inspection and Safety Program, the compliance regime most of the industry still calls Local Law 11. FISP runs under section 28-302 of the New York City Administrative Code, with the operating rules at 1 RCNY 103-04.

There is a second signal most people miss. Of the 14,769 shed-referencing permits in our file over the last twelve months, 9,116 are building-type filings for the shed itself and 5,623 are electrical filings for its temporary lighting. The lighting is usually a different contractor. One shed produces two permits, filed days or weeks apart, and the electrical one is often the easier record to spot.

This is where the anchor idea does real work. A permit is a signal about the property owner, not the contractor. The firm that put up the shed already has its money. The owner standing underneath it has a repair to buy, an engineer to retain, and now a renewal deadline.

Why did the shed clock just shrink to 90 days?

Because the city decided that leaving a shed up had become cheaper than fixing the wall behind it.

Five local laws approved on April 17, 2025 form the package known as Get Sheds Down. Two of them matter for prospecting.

Local Law 48 of 2025 governs the permit itself. The term is 90 days. Renewals no longer happen automatically in DOB NOW, so each one is a manual submission with a base fee reported at $130, and each must carry a written progress report from a Registered Design Professional setting out what work has been done and explaining any delay. From the second renewal, a shed erected for facade or building repair cannot be renewed at all without a DOB penalty being paid.

Local Law 51 of 2025 governs the work behind the shed. Once the permit is issued, the owner has five months to file construction documents, eight months to file an acceptable work permit application, and two years to finish the repairs. Penalties for failing to resolve an unsafe facade condition run from $5,000 to $20,000.

Read those two together and the sales calendar writes itself. Month one, the shed goes up. Month five, construction documents are due, which means an engineer or architect has to be engaged well before that. Month eight, the work permit application is due, which means the restoration contractor has to be chosen and priced before that. Every one of those deadlines is a purchase.

How long is the gap between the shed and the repair permit?

Eighty-one days, at the median, measured across every New York City address in our file that pulled a shed permit since January 2021 and later filed repair work at the same address.

Of the 13,112 distinct shed addresses in that period, 3,704 produced a subsequent facade, pointing, parapet, brick or lintel permit. Of those, 2,224 filed within 180 days.

Two honest caveats, because a number like this is only useful if you know its edges. We identify repair filings by matching text in the work description, so jobs described in other wording are not counted, which makes 28.2% a floor rather than a precise conversion rate. And the addresses that never file repair work are not all failures of the model. Some sheds are for construction. Some owners stall, which is precisely the behaviour Local Law 51 was written to punish.

Which boroughs convert, and which ones stall?

Manhattan converts best and Brooklyn converts worst, and the gap between them is wider than the gap between most trades.

Borough	Shed addresses since 2021	Later filed repair	Conversion	Median gap
Manhattan	5,703	1,979	34.7%	80 days
Brooklyn	3,552	680	19.1%	82.5 days
Bronx	2,095	620	29.6%	94.5 days
Queens	1,643	396	24.1%	55 days
Staten Island	119	29	24.4%	214 days

Manhattan's building stock is older, taller and more heavily governed by FISP, so a shed there is far more likely to sit in front of a genuine facade program. Brooklyn's number is dragged down by a wider mix of low-rise and new-construction work.

Queens is the interesting one. It converts at a middling rate but moves fastest, with a median of 55 days from shed to repair filing. If you sell in Queens, your follow-up cadence should be roughly a month tighter than a Manhattan competitor's. Staten Island, with 119 shed addresses since 2021 and 88 shed permits in the last year, is too thin to build a territory on.

Where is the backlog of sheds with no repair filed?

In 4,424 addresses across the city, and that cut is the most commercially interesting one in this article.

Take every New York City address that pulled a shed permit between January 2024 and February 2026, then keep only those where no repair permit has been filed at least 180 days later. Manhattan holds 1,759 of them, Brooklyn 1,324, the Bronx 703, Queens 590 and Staten Island 48. That is 4,424 out of 8,800 shed addresses in the window, so roughly half.

Those owners are past the five-month construction-document milestone. Many are past the eight-month work-permit milestone. They are carrying a shed, paying quarterly renewals, filing progress reports through a design professional, and facing penalties that start at $5,000. They have a problem that has become more expensive to ignore than to solve.

That is a qualified list, not a cold one.

How should you time the outreach?

Work the fresh shed filing immediately, work the stalled backlog constantly, and stop treating them as one list.

For a new shed permit, the first touch belongs in the first two weeks, well before the 81-day median. You are not selling the repair yet. You are getting in front of whoever will scope it, which at that stage is usually the engineer or the managing agent. The same logic that governs responding fast to a fresh permit filing applies here, with a longer runway than most trades ever get.

For the stalled backlog, the pitch inverts. Those owners have heard from restoration contractors already. What they have not heard is a specific reference to where they sit against the Local Law 51 milestones and what the next renewal is going to cost them. That is a compliance conversation, and it converts differently.

Both lists need somewhere to live. A 90-day permit cycle with five-month and eight-month milestones behind it is a sequence rather than an event, so it belongs in a CRM set up around permit triggers, not a spreadsheet. The broader case for working real filings instead of buying shared inquiries is in permit data compared with lead lists.

One more filter worth applying. Only 312 firms filed the building-type shed permits in the last twelve months, and every one of those records carries a contractor name. Those firms see the facade job before anyone else does, which makes them a referral channel rather than a competitor for most trades.

How permits.llc fits in

We hold 383,468 New York City permit records covering all five boroughs, sourced from the Department of Buildings and current to within a day or two of publication. Every cut in this article came out of that file: the shed-to-repair sequence, the borough conversion rates, and the stalled backlog.

A caution on scope, because it decides whether this is your dataset. Our New York coverage is New York City only. There is no upstate, Long Island or Westchester data, and New York City administers its own Construction Codes, so the rules described here do not travel outside the five boroughs. The wider picture of what the DOB file holds is in our five-borough map of NYC permit leads.
