New Sidewalk Shed Requirements in NYC: What Changed in 2026

Sidewalk shed rules in New York City changed more in 2026 than in the previous decade. Permits that used to run a year now expire every 90 days, every renewal needs a registered design professional, and owners whose facade repairs stall face monthly penalties. At the same time, the physical requirements for the shed itself (height, width, lighting, deck strength) have not moved. This guide separates what is new from what still applies, with the primary source for each point.

What changed in 2026

1. Permits last 90 days, not a year

Under the Department of Buildings service notice of January 8, 2026 (Local Laws 48 and 51 of 2025), every sidewalk shed permit issued or renewed in DOB NOW from early 2026 has a maximum duration of 90 days. Permits are not renewed automatically; each one must be renewed by hand every 90 days from the date of issuance, with a $130 renewal fee each time. Older DOB pages still describe one-year initial permits; the 2026 notice governs.

2. A registered design professional is part of every permit

For sheds that are not exempt, the same notice adds a registered design professional (a Professional Engineer or Registered Architect) to the PW2 as a stakeholder. That professional must log in to DOB NOW and answer questions about the progress of the work the shed protects when the permit request is submitted and at each renewal.

DOB rule 1 RCNY 102-07 sets out what sits behind those answers: a report based on a physical examination, meaning an in-person visual inspection of the premises the shed is associated with. The initial examination is done by the registered design professional; later ones may be done by the professional or a designee.

3. Work has to be in progress, or the owner pays

Local Law 48 of 2025 added section 28-220.1 to the Administrative Code. Beginning with the second renewal, each renewal requires the building owner to be doing the work the shed was put up for. Where work is not in progress during a renewal period, the penalty is assessed per linear foot of shed per month and must be paid before the permit can be renewed:

• Shed in place less than 3 years: $10 per linear foot per month.
• 3 years but less than 4 years: $100 per linear foot per month.
• 4 years or more: $200 per linear foot per month, with penalties in this tier capped at $6,000 per month.

The $6,000 monthly cap is written into the 4-year tier only. The law exempts one- and two-family homes and sheds installed for permitted new building, enlargement or demolition work.

4. Separate fines for missing reports and facade milestones

1 RCNY 102-07 adds fixed penalties: $2,500 for failing to file an acceptable progress report when renewing the permit, and one-time penalties for facade repairs that fall behind the Local Law 51 milestones: $5,000 if complete construction documents are not filed within 5 months of the initial shed permit, $10,000 if a complete permit application is not filed within 8 months, and $20,000 if the permitted repair work is not complete within 2 years. An owner or the registered design professional can file an extension request no earlier than 60 days and no later than 20 days before a milestone.

What has not changed: the shed itself

DOB’s sidewalk shed requirements under Building Code chapter 33 (section 3307) still set the physical design. From DOB’s sidewalk sheds page:

• When a shed is required: constructing a building more than 40 feet high, demolishing a building more than 25 feet high, and whenever danger makes this protection necessary.
• Length: along the property line, and 20 feet into adjacent properties at buildings higher than 100 feet.
• Width: 5 feet minimum and enough for foot traffic.
• Passageway height: 8 feet minimum clearance, lit by natural or artificial light at all times.
• Deck strength: at least 300 pounds per square foot, or 150 pounds per square foot for sheds without storage at buildings under 100 feet high.
• Fire escapes and exits may not be blocked; loading openings must be protected; DOT street signs must stay visible.
• A shed that extends into the street also needs a Building Operation Permit from the NYC Department of Transportation before DOB approves the work permit.

Sheds may not be built without DOB’s prior approval and a work permit, except when there is an immediate threat to safety, in which case the owner may build the shed and file the application within 24 hours. And sheds must be removed immediately once the construction, demolition or remediation work is complete (see how shed removal works in DOB NOW).

What may change next: standard shed designs

DOB has proposed a new rule, 1 RCNY 3307-03, that would let registered design professionals use one of six DOB standard sidewalk shed designs. The public hearing and comment period closed on September 24, 2026, and as of November 11, 2026 the rule is still listed as Proposed, with no adoption or effective date. Until it is adopted, the current code requirements above apply to every shed, and even under the proposed rule the registered design professional remains responsible for site-specific conditions.

What this means in practice

• Owners and managers: every shed now has a calendar. Put the 90-day renewal dates and, for facade sheds, the 5-month, 8-month and 2-year milestones on it, and keep the work moving so no renewal period passes without progress.
• Contractors: the shed permit now depends on an engineer being available at every renewal, not only at the initial filing. Line up the renewal report before the permit expires.
• New sheds: the design still has to meet section 3307 and be sealed and filed by a licensed professional. See our sidewalk shed engineering page for what a filing needs.
