Key takeaways
- Beginning November 2, 2026, requests to extend the 5-month, 8-month and 24-month sidewalk shed milestones are submitted in DOB NOW: Safety.
- The milestones sit in §28-220.2.1 of the Administrative Code and 1 RCNY §102-07. Missing one without an accepted extension costs $5,000, $10,000 or $20,000.
- The window is short and it is the part people miss: no earlier than 60 days before the first milestone deadline, and no later than 20 days before the deadline you are extending.
- A separate request for each milestone, each with its own fee and its own supporting documents.
In this article
A sidewalk shed goes up in a week and comes down years later. In between there are now three dated gates, each with a penalty attached, and from today the request for more time goes somewhere new.
What changed
Beginning November 2, 2026, extension requests for the sidewalk shed milestones are filed in DOB NOW: Safety rather than where they went before.
The milestones themselves are not new. They come from Local Law 51 of 2025, sit in §28-220.2.1 of the Administrative Code, and the detail is in 1 RCNY §102-07: 1_RCNY_102-07.pdf. What changed today is the door you knock on.
The three gates, and what they cost
Each one is measured from the issuance of the initial shed permit, not from when the work started.
| Milestone | What has to be done | Penalty if missed |
|---|---|---|
| 5 months | Complete construction documents filed | $5,000 |
| 8 months | Complete permit application filed | $10,000 |
| 2 years | Permitted work completed | $20,000 |
The penalties are one-time, not daily, and they apply unless an extension request has been filed and accepted. A request that was filed and then denied does not protect you.
The window is the part people miss
This is where the money is lost, and it has nothing to do with the merits of the request.
A request may be filed no earlier than 60 days before the first milestone deadline, and no later than 20 days before the deadline it relates to.
Twenty days. Not the day before, not the week before. If a project manager looks at the calendar with two weeks to go and decides to ask for more time, it is already too late — and the penalty is then automatic, however good the reason was.
What a request has to carry
The request is filed by the Registered Design Professional, not by the owner directly, and it comes with a fee that is not refunded if it is denied.
| Extension | Filing fee |
|---|---|
| Construction documents (5 months) | $410 |
| Permit application (8 months) | $465 |
| Completion of work (2 years) | $1,425 |
Beyond the fee, each request carries supporting documents: why the deadline cannot be met, a project schedule, the contract, a summary of the permits the job needs, and whatever else applies. The 5-month request also needs progress drawings or a written account of the work still to be done.
A separate request for each milestone. One filing does not move all three.
How much time you get
For the 5-month and 8-month milestones, the Commissioner may grant extensions in increments of up to 180 days. For the 2-year milestone, a single extension of a longer period.
So the early gates can be moved more than once, in steps. The last one is a single conversation, and you want to have it well before the two years are up.
Objections: two rounds and you are out
If the Department raises objections, a revised request must be filed within 14 days.
The request is denied if the revision is late, or if it is still not accepted after two rounds of objections. A denied request can be submitted again, but with a new fee — and if no accepted request exists when the milestone passes, the penalty applies as if nothing had been filed.
That is the real argument for filing at the start of the window rather than the end: a rejected first attempt still leaves room for a second.
What to do
- Put the three dates in the schedule the day the shed permit issues, counted from the permit date. Not from the start of work.
- Set a reminder 60 days before each one, which is the day the window opens. That is when the conversation should start, not when it should end.
- Decide early who files. It is the Registered Design Professional, and they need the documents from you before they can.
- Budget the fees as part of the job, not as a surprise. On a long facade repair, all three can come up.
- Treat a first objection as normal, and answer it inside the 14 days. The second round is the last one.
None of this changes the inspection scope on the repair itself. The special inspections your permit calls for run on the construction schedule, and the categories come from the permit, not from the shed. What the shed clock governs is how long the city lets the work take.
The other half of the sidewalk shed rules — the 90-day permits, the progress reports and the renewal fees — is in sidewalk sheds in NYC: 90-day permits, progress reports and the new fees. And if your shed covers a plain facade, the 40-foot cap may let you shorten it.
Frequently asked questions
Where do extension requests go now?
In DOB NOW: Safety, beginning November 2, 2026.
When is the earliest I can file?
60 days before the first milestone deadline. The latest is 20 days before the deadline you are extending.
Can one request cover all three milestones?
No. A separate request, with its own fee and documents, for each one.
What happens if the request is denied?
You can file again with a new fee. But if no accepted request exists when the milestone passes, the penalty applies — $5,000, $10,000 or $20,000 depending on which one.
Who files it?
The Registered Design Professional, on the owner's behalf.
Conclusion
The shed clock is unusual in that the penalty does not depend on anyone inspecting anything. It runs on a date, and it collects on a date. The cheapest thing on this page is the reminder you set 60 days ahead; the most expensive is the one you set for the week of the deadline.
