NYC Sidewalk Shed Permit Data Report: Q1 2026 Analysis

Five contractors control nearly 29% of all sidewalk shed permits ever issued in New York City. Meanwhile, 7,859 active sheds stretch across 380 miles of city sidewalks (enough to reach from Lower Manhattan to Richmond, Virginia) [1]. And 372 of those sheds have been standing for more than five years.

This is the first quarterly NYC sidewalk shed data report from The Shed Registry. It draws on 153,944 permits issued to 588 contractors in the NYC Open Data DOB Sidewalk Sheds dataset [2], cross-referenced with citywide figures from the Mayor's office and the Department of Buildings (DOB). The goal is straightforward: give building managers, policymakers, and journalists a single reference point for NYC sidewalk shed statistics in 2026, updated quarterly, methodology transparent, every number sourced.

If you're a building manager facing a 90-day permit renewal under Local Law 48, the contractor rankings in this report are directly relevant to your next hire. If you're a journalist, the borough breakdowns and market concentration figures are designed to be quoted.

Citywide snapshot: where things stand in Q1 2026

The city's sidewalk shed problem peaked several years ago. It hasn't gone away.

As of March 2026, the Mayor's office reports 7,859 active sidewalk sheds covering approximately 380 miles of sidewalk (roughly 7,500 city blocks) [1]. The "Get Sheds Down" initiative, launched under former Mayor Adams in July 2023, has produced a 17% decline from peak levels [1]. More than 15,200 sheds have been removed since the program began, including 429 long-standing sheds that had been up for five or more years [1].

But the numbers still tell a story of systemic delay. 372 sheds remain standing after five or more years [1]. The longest-ever documented shed, at 409 Edgecombe Avenue in Washington Heights, stood for 21 years before its removal in December 2023 [3].

The new Mamdani administration has signaled it will continue and expand shed reduction efforts. In March 2026, the Mayor's office announced a proposed 40-foot limit on shed extensions, new NYCHA facade investments totaling $650 million across 40 developments, and a 180-day penalty threshold with mandatory 90-day status updates for long-standing sheds [1].

Borough breakdown: NYC sidewalk shed statistics by geography

Manhattan dominates. That won't surprise anyone who walks its sidewalks. But the scale of the imbalance, and what it means for contractors and building managers in each borough, is worth examining.

Permits by borough

Source: The Shed Registry analysis of NYC Open Data DOB Sidewalk Sheds dataset (153,944 total permits) [2].

Manhattan accounts for 56.9% of all permits but only 41.8% of contractors (246 of 588). That ratio matters. It means Manhattan building managers face the highest competition for contractor availability, with more permits per contractor than any other borough. During peak enforcement periods under Local Law 48, scheduling bottlenecks in Manhattan are a realistic concern.

Brooklyn holds 21.4% of permits and has seen rapid growth in shed volume over the past decade. The Bronx and Queens each account for roughly 10% of permits. Staten Island, with just 1,225 permits (0.8%), is a fundamentally different market where only one contractor lists it as a primary borough.

Contractors by primary borough

Building managers in Queens and Staten Island face a different problem than those in Manhattan: not scheduling pressure, but limited contractor options. With only 19 contractors listing Queens as their primary borough and one in Staten Island, the selection pool is thin. The full contractor directory allows filtering by borough to see which firms actively hold permits in each area.

Market concentration: the contractors behind the sheds

The NYC sidewalk shed market is remarkably concentrated. A small number of firms hold a disproportionate share of all permits, a structural reality that building managers, regulators, and anyone analyzing this market should understand.

Top 10 contractors by total permits

Source: The Shed Registry analysis of NYC Open Data DOB Sidewalk Sheds dataset [2].

What this data reveals

The top five contractors hold 44,469 permits, representing 28.9% of all permits in the dataset. Rockledge Scaffold alone accounts for 12,873 permits, approaching the total for the entire borough of Queens (15,636). This level of concentration means that the performance, pricing, and availability of a handful of firms shapes the sidewalk shed landscape for the entire city.

Active permit retention is extraordinarily high. Across the top 10, an average of 97.6% of permits remain active or issued. That figure does not mean 97% of sheds are currently standing; "active" in the DOB dataset includes permits that have not been formally closed. But it does suggest that permit closeout is not happening at scale, which aligns with the citywide problem of sheds staying up far longer than necessary.

Only two contractors operate across all five boroughs: Outdoor Installations LLC and CS Bridge Corp. Most firms concentrate in two or three boroughs. Building managers in outer boroughs should verify that a contractor has actual permit history in their borough, not just a claim of service coverage. The contractor directory shows borough-level permit data for every firm.

The Manhattan problem: 56.9% of permits, 41.8% of contractors

Manhattan deserves its own section in any sidewalk shed data analysis. The borough's share of the problem is not proportional; it's dominant.

With 87,555 permits (56.9% of all NYC permits) and 246 contractors (41.8% of the 588 in our dataset), Manhattan has the highest permits-per-contractor ratio of any borough. That means more competition for scheduling, more pressure on contractor availability, and (under Local Law 48's 90-day permit cycle) more risk of renewal delays.

The Upper East Side and Midtown are tied at roughly 550 active permits each, making them the highest-density neighborhoods for sidewalk sheds in the city. The Upper West Side follows closely with approximately 522 permits. Building managers in these neighborhoods are not just competing with other buildings for contractor time. They're competing with entire blocks of simultaneously expiring 90-day permits.

For building managers in Manhattan, the takeaway is practical: start contractor selection early, verify that the firm has current Manhattan permit activity, and don't assume availability. Browse Manhattan contractors ranked by permit volume to build a shortlist.

Business impact: what sheds cost beyond penalties

The financial impact of sidewalk sheds extends well beyond the penalty structure of Local Law 48. A 2024 study commissioned by former Mayor Adams, conducted in partnership with Mastercard, quantified the damage to Manhattan businesses [4].

Businesses under sidewalk sheds lose $3,900 to $9,500 per month in revenue. Restaurants and bars are hit hardest, experiencing a 3.5% to 9.7% decline in weekly transactions while a shed is in place [4]. These are not estimates from surveys. They're transaction-level data from Mastercard's payment network.

For building owners, the direct costs compound. Installation typically runs $100 to $180 per linear foot, with monthly rental of $15 to $45 per linear foot depending on borough, based on contractor bid data and industry pricing. Add Local Law 48 penalties of $10 to $200 per linear foot per month (capped at $6,000/month) [5] and the economics of inaction become untenable.

There's a perverse incentive embedded in the old system: for years, it was cheaper for building owners to keep renting a shed than to pay for the underlying facade repair. Local Law 48's escalating penalties are designed to break that cycle by making delay more expensive than repair. Whether it works depends on enforcement, and enforcement depends on the 90-day renewal process functioning as designed.

Building managers can estimate their penalty exposure using the interactive calculator and compare shed costs per linear foot in our cost guide.

Regulatory landscape: Local Law 48 and the new enforcement regime

The legislative environment for sidewalk sheds changed fundamentally in early 2026. Building managers operating under the old assumptions (annual permits, minimal reporting, low consequences for delay) need to recalibrate.

Local Law 48 (effective January 26, 2026)

The centerpiece of the "Get Sheds Down" package [5]. Key provisions:

• 90-day permit cycle replaces the former 12-month permits
• Licensed professional progress report required at each renewal
• Escalating penalties: $10/lf/month (under 3 years), $100/lf/month (3-4 years), $200/lf/month (over 4 years)
• $6,000/month cap on penalties regardless of shed length
• Penalties must be paid before permit renewal, meaning unpaid fines block the renewal process

Related legislation

Local Law 51 adds milestone penalties on top of LL48: $5,000 for missing the 5-month construction document filing deadline, $10,000 for missing the 8-month permit application deadline, and $20,000 if repairs aren't completed within two years [6]. These are additive; a building owner can owe LL51 milestones and LL48 monthly penalties simultaneously.

Local Law 47 sets new design standards for sheds, including 12-foot minimum height and LED lighting requirements [7].

The Facade Inspection & Safety Program (FISP) cycle is also shifting. Effective October 2026, the inspection cycle changes from five years to a range of 6 to 12 years, depending on building condition. A City Council study on the new cycle is expected in Q2 2026.

For a detailed walkthrough of how penalties calculate and what exemptions apply, see the Local Law 48 penalty calculator guide.

What to watch in Q2 2026

Several developments will shape the sidewalk shed landscape over the next quarter. Building managers and contractors should track these closely.

Local Law 48 enforcement ramp-up. The first full quarter of LL48 enforcement will produce the first wave of penalty assessments at scale. The DOB's capacity to process 90-day renewals for thousands of active permits simultaneously has not been tested. Bottlenecks are possible.

FISP cycle study. The City Council is expected to receive a study on the new 6-to-12-year FISP inspection cycle. This will affect long-term shed demand, since FISP-related facade work is a primary driver of shed installations.

New shed designs. Local Law 47's design requirements [7], including expanded color options and improved lighting, will begin appearing on city streets. The aesthetic impact is secondary to the structural question: will new designs cost more and affect contractor pricing?

NYCHA's $650 million facade program. The city's commitment to remove sheds from 200+ NYCHA buildings and invest in facade repairs across 40 developments [1] will redirect significant contractor capacity toward public housing. Private building managers should factor this demand into their scheduling assumptions.

The Shed Registry's Q2 2026 report will measure LL48's impact on permit closures, track changes in borough-level shed counts, and update contractor rankings. The contractor directory is updated regularly with the latest NYC Open Data permit information.

Methodology

This report analyzes 153,944 sidewalk shed permits issued to 588 contractors with 25 or more total permits in the NYC Open Data DOB Sidewalk Sheds dataset [2]. The dataset covers all five boroughs and includes both active and historical permits.

Contractor rankings are based on total permit count and active (issued) permit count as recorded in the dataset. Borough assignments reflect the boroughs where each contractor holds permits. "Primary borough" refers to the borough where a contractor holds the most permits.

Citywide statistics (7,859 active sheds, 380 miles, 17% decline) are sourced from the Mayor's office March 2026 announcement [1]. Business impact figures are from the Adams/Mastercard study published August 2024 [4]. Legislative details reference the full text of Local Law 48 [5] and the NYC Council's Get Sheds Down legislation [8].

The raw dataset is publicly available on the NYC Open Data portal [2].

Key takeaways

• 7,859 active sidewalk sheds cover 380 miles of NYC sidewalks, down 17% from peak, but 372 have been standing for 5+ years [1]
• Manhattan holds 56.9% of all permits but only 41.8% of contractors, creating scheduling pressure under LL48's 90-day cycle [2]
• The top five contractors control 28.9% of all permits, a level of market concentration that affects availability, pricing, and enforcement outcomes [2]
• Active permit retention averages 97.6% across the top 10 contractors, indicating that permit closeout is not happening at scale
• Local Law 48 penalties of $10 to $200 per linear foot per month (capped at $6,000/month) make delay more expensive than it's ever been [5]
• Businesses under sheds lose $3,900 to $9,500 per month in revenue, with restaurants hit hardest [4]

Building managers should compare contractors by permit volume and borough coverage before their next 90-day renewal window.
