How long sidewalk sheds stay up on NYC facade repair cases

The short answer: no fixed limit, but waiting now costs money

New York City sets no maximum time for a sidewalk shed. A shed needs a permit from the Department of Buildings, and the permit has an expiration date, so the owner has to renew it to keep the shed up. Many sheds have stood for years that way.

Local Law 48 of 2025 changed the math. From the second renewal of a shed permit issued after Jan 12, 2026, each renewal requires work on the condition behind the shed. For every month without work in progress the owner may be liable per linear foot of shed: $10 while the shed is less than 3 years old, $100 from 3 years and $200 from 4 years; only the $200 tier is capped, at $6,000 per month (Admin Code § 28-220.1). Sheds first permitted on or after Jan 12, 2026 also fall under the repair milestones of Local Law 51. Rates, milestones and sources are on our LL48 and LL51 penalties page, and the shed penalty calculator estimates a single shed.

What shed age tells you about the repair job

Sheds mostly sit on UNSAFE cases. 63 of the 69 sheds stand on buildings whose cycle 10 report is UNSAFE; only 6 of the 491 open SWARMP cases have one. An UNSAFE rating obliges the owner to protect the public right away and to correct the condition within 90 days of filing the report, unless the Department of Buildings grants an extension (see SWARMP explained). A shed is the visible sign that this clock is running and the repair has not been filed.

Most sheds were up before the current report. 55 of the 69 sheds were already standing when the cycle 10 report was filed, and 15 of these buildings were rated UNSAFE in cycle 9 as well. On these buildings the problem is not new; the repair simply has not been filed yet.

Under one year (36 sheds): usually a recent UNSAFE finding. The owner is at the start: the engineer of record writes the scope, the managing agent collects bids. Where Local Law 51 applies (30 open cases), construction documents are due 5 months after the first shed permit, and a complete repair permit application must be filed in time for the permit to be issued within 8 months. For a contractor this is the best time to be on the bidder list.

One to three years (15 sheds): the scope may exist, but no repair permit is on file. Once the second renewal after Jan 12, 2026 is reached, every month without work can cost $10 per foot of shed. Pressure is rising, and the owner has a reason to move.

Three years or more (18 sheds): the job has stalled for a long time, and public data does not show why. These sheds sit in the $100 and $200 tiers once LL48 applies, so the monthly cost of waiting is ten to twenty times higher than on a new shed. Check the history before you call: our case sheet shows whether a contractor already did facade work on the building, and who filed the report.

For comparison, in cycle 9 the UNSAFE reports that got a repair filing at all (60%) reached it after a median of 213 days, the SWARMP reports that got one (49%) after 620 days; after 24 months only 35% of all reports had a repair filing (one-time analysis of cycle 9, as of Oct 23, 2026; our track record). A shed that has stood for years is far beyond that.

What this page does and does not count

The numbers cover sheds on the buildings on our list: buildings with a cycle 10 SWARMP or UNSAFE facade report and no repair filing or repair permit since the report. Sheds on other buildings (construction sites, buildings already under repair, public and NYCHA buildings) are not included. Shed age is counted from the first permit of the shed job; a shed whose permit was signed off no longer counts as standing. Shed length is not in public data, so dollar amounts use the building front from PLUTO and are estimates.
