Scaffolding Contractor Speed of Removal: Permit Rankings

Every NYC scaffolding contractor claims fast turnaround. The permit record tells a different story. Across 153,944 sidewalk shed permits in the NYC Open Data DOB Sidewalk Sheds dataset [1], the median contractor has a permit turnover rate of just 0.9%. That means, for the typical firm, fewer than 1 in 100 permits have been formally closed.

Say you're comparing bids from two contractors. Both promise quick removal. One has a 5% permit turnover rate. The other has 0%. The marketing reads the same. The permit record does not.

This guide ranks NYC scaffolding contractors by permit turnover rate, the closest data-driven proxy for speed of removal available in the public record. It draws on the same 411-contractor, 153,944-permit dataset behind the Q1 2026 NYC sidewalk shed data report. You can compare contractors by borough, permit volume, and history directly in The Shed Registry.

What "speed of removal" actually means in the permit record

No public dataset tracks the exact date a sidewalk shed was taken down. What the NYC Open Data record does capture is whether each permit is ISSUED (active, shed still standing) or EXPIRED (closed, shed removed) [1].

Permit turnover rate is the ratio of EXPIRED permits to total permits for a given contractor. A higher rate means a larger share of that contractor's historical permits have been formally closed, indicating completed jobs where the shed came down and the permit was resolved. A lower rate means more of their permits remain open.

Each sidewalk shed permit now runs on a 90-day cycle under Local Law 48 of 2025 [2]. Every renewal represents another quarter the shed stayed up. The number of renewal sequences at a given address is a second proxy for duration: more renewals, longer lifecycle.

This is not a perfect measure of speed of removal. Multiple factors beyond contractor control affect how long a shed stays up (DOB inspection backlogs, financing delays, underlying repair timelines). But turnover rate reveals patterns that marketing pages do not. For the physical removal process and timeline breakdown, see the fast sidewalk shed removal contractors guide.

Permit turnover rankings: which contractors complete jobs

We analyzed 189 contractors with 100 or more total permits in the dataset to ensure statistical significance. The findings split into two tables: the contractors with the highest turnover rates and the top five by volume with their turnover rates.

Highest permit turnover rates (100+ permits)

Turnover rates per The Shed Registry analysis of NYC Open Data DOB Sidewalk Sheds dataset [1]. Minimum 100 total permits for inclusion.

Portchester Scaffolding (7.9%) and ACE Scaffold (7.7%) stand out among firms with 700+ permits. At that volume, a turnover rate in the 7 to 8% range represents dozens of completed permit cycles, not a statistical artifact.

Top five by volume and their turnover rates

Turnover rates per The Shed Registry analysis of NYC Open Data DOB Sidewalk Sheds dataset [1].

The five largest contractors by permit volume all have turnover rates at or below 5.1%. Colgate Scaffolding leads this group at 5.1%, more than five times the median. Everest Scaffolding has the lowest at 0.6%. For permit volume rankings by borough, see the permit volume leaders guide.

What the turnover distribution reveals

Across all 189 contractors with 100+ permits, the distribution of turnover rates looks like this:

• Minimum: 0.0% (46+ contractors with zero expired permits)
• 25th percentile: 0.2%
• Median: 0.9%
• Mean: 2.1%
• 75th percentile: 2.9%
• Maximum: 30.1%

Say you are comparing three bids for your building's sidewalk shed. You can now check each contractor against these benchmarks. A turnover rate above 2.9% places a firm in the top quartile for speed of removal. Below 0.2%, the bottom quartile. That single data point adds more objectivity than every marketing page combined.

The 46+ contractors with exactly 0% turnover (zero expired permits despite holding 100+ active ones) are worth noting. A 0% rate doesn't necessarily mean the contractor never completes jobs. It can mean the firm is growing quickly and all permits are recent. But it can also mean no sheds have been formally closed under their name in the dataset. For building managers, a 0% rate is a signal to ask harder questions during procurement, not an automatic disqualifier.

Why turnover rate isn't the whole story

Permit turnover rate is one signal, not the final word. Several factors outside a contractor's direct control affect how long sheds stay up.

Underlying repair completion. A sidewalk shed can't legally be removed until the facade work it protects is finished [3]. If the facade contractor has not completed repairs, the shed stays regardless of the scaffolding contractor's readiness. This is the most common reason for extended timelines.

DOB inspection backlogs. Before a permit can be closed, the DOB must conduct a final inspection. Scheduling varies by borough and workload. There is no public dashboard for real-time inspection wait times [3].

Landmark status. Buildings with Landmarks Preservation Commission designation require additional review, adding months to the process. Landmarked buildings tend to keep sheds approximately 23% longer than non-landmarked ones [4]. Manhattan's high concentration of landmarked buildings contributes to longer duration patterns in that borough.

Financing and ownership structure. For co-op boards, the timeline includes board votes, special assessments, and shareholder communication. For NYCHA buildings, deferred maintenance has historically stretched timelines, though the city's $650 million facade investment across 40 NYCHA developments aims to accelerate that [5].

How to use this data when choosing a contractor

Turnover rate works best as part of a multi-signal evaluation, not as a standalone speed of removal ranking. Here is a practical framework you can apply during procurement:

1. Check turnover rate. Use the rankings above. Is the contractor above the median (0.9%)? Above the 75th percentile (2.9%)? A rate in the top quartile is a positive signal.
2. Cross-reference with permit volume. High turnover and high volume together suggest the contractor both takes on work and finishes it. A contractor with 800+ permits and a 7%+ turnover rate (like Portchester Scaffolding or ACE Scaffold) has demonstrated completion at scale. Use the permit volume leaders by borough guide for volume rankings.
3. Verify borough presence. Your contractor's citywide turnover rate may differ from their performance in your specific borough. Check the contractor directory filtered to your borough.
4. Ask about current capacity and scheduling. Data reveals historical patterns. Current crew availability and project load require a direct conversation. See the questions to ask scaffolding contractors before hiring guide for a full question list.
5. Factor in LL48 penalty exposure. Under Local Law 48, penalties escalate from $10 per linear foot per month (under 3 years) to $100 (3 to 4 years) to $200 (over 4 years), all capped at $6,000 per month [2]. Faster removal directly reduces your penalty exposure. Estimate it with the Local Law 48 penalty calculator.

Frequently asked questions

What is permit turnover rate and how is it calculated?

Permit turnover rate is the percentage of a contractor's total sidewalk shed permits that have been formally closed (status changed from ISSUED to EXPIRED). It is calculated as: (EXPIRED permits / total permits) x 100. The data comes from the NYC Open Data DOB Sidewalk Sheds dataset [1].

Does a high permit volume mean faster removal?

Not necessarily. The five largest contractors by permit volume all have turnover rates below 5.1%. High volume can indicate scale and operational capacity, but it doesn't automatically translate to faster project completion. Turnover rate is a more direct signal for completion patterns.

Why do some contractors have zero expired permits?

There are 46+ contractors with 100 or more permits and a 0% turnover rate. This can mean the firm is relatively new or growing quickly (all permits are recent), or that no permits have been formally closed. In either case, building managers should ask directly about completed project histories.

How does Local Law 48 affect removal speed?

Local Law 48 of 2025 imposes escalating monthly penalties on idle sheds: $10 per linear foot under 3 years, $100 between 3 and 4 years, and $200 beyond 4 years, capped at $6,000 per month [2]. These penalties create a financial incentive for building owners to choose contractors who complete work on schedule.

Can I filter contractors by turnover rate on The Shed Registry?

The Shed Registry currently displays permit volume, borough coverage, and contractor history. Turnover rate as a filter is not yet available in the directory, but you can cross-reference any contractor's active and total permit counts to estimate their turnover rate. Browse the directory to compare contractors.

What is the fastest way to get a sidewalk shed removed?

The fastest scaffolding removal contractors NYC building managers can hire still depend on the underlying facade work being complete first. Once repairs are finished, the physical removal typically takes 1 to 3 days. The controllable variable is choosing a contractor with a track record of closing out permits, which is exactly what turnover rate measures. For the full physical removal process, see the fast removal contractors guide.
