Local Law 51 of 2025: Facade Repair Milestones, Penalties, and Extensions

The short version: your shed permit date now starts a repair clock with real deadlines

If your building’s first sidewalk shed permit for a facade condition was issued on or after January 12, 2026, three deadlines are already running, whether or not anyone on your board has looked at them: construction documents due in 5 months, a complete permit application due in 8 months, and the repair work itself completed within 2 years. Miss one and NYC DOB can hit the owner with a penalty of $5,000 to $20,000 for that milestone alone.

This is Local Law 51 of 2025, part of the city’s “Get Sheds Down” package that Mayor Adams signed on April 17, 2025 alongside its companion, Local Law 48. We covered Local Law 48’s 90-day shed permit renewal and idle-shed penalties in a separate post; this one is about Local Law 51 on its own — the deadlines for the actual repair work, the penalty amounts, and how to request more time if your project genuinely needs it.

For a visual walkthrough, see our briefing slides: Your façade clock and your sidewalk shed.

What Local Law 51 actually changed

Local Law 51 adds a new section, § 28-220.2, to Article 220 of Title 28 of the NYC Administrative Code — the same article Local Law 48 created for sidewalk shed penalties. Where an initial permit for a sidewalk shed in the public right-of-way is issued on or after the law’s effective date, the owner of the building is subject to three separate milestone deadlines, measured from that initial permit’s issue date:

1. 5 months — complete construction documents to repair the unsafe facade condition must be filed with DOB.
2. 8 months — a complete repair permit application must be filed and diligently pursued, including responding to plan-exam objections in a timely manner.
3. 2 years — the permitted repair work itself must be completed, unless DOB granted an extension.

Each missed milestone carries its own penalty, in the $5,000 to $20,000 range set by the law. The exception: sidewalk sheds installed in connection with permitted new building, enlargement, or demolition work are not subject to these penalties, since that work already runs on its own permit and inspection schedule.

What the implementing rule pins down: exact dollar amounts and fees

Local Law 51 left the exact penalty amount within its $5,000-$20,000 range, and the extension process, to DOB rulemaking. DOB adopted that rule, 1 RCNY § 102-07, which took effect August 13, 2026. It sets a fixed penalty for each of the three Local Law 51 milestones, rather than leaving it to case-by-case discretion within the statutory range:

Missed milestone	Penalty
Complete construction documents not filed within 5 months	$5,000
Complete permit application not filed within 8 months	$10,000
Repair work not completed within 2 years	$20,000

Source: 1 RCNY § 102-07, subdivision (g).

The same rule also sets filing fees for the paperwork around these deadlines, including extension requests:

Filing	Fee
Extension request — construction documents (5-month milestone)	$410
Extension request — permit application (8-month milestone)	$465
Extension request — complete the repair (2-year milestone)	$1,425
Progress report required at each sidewalk shed permit renewal	$90
Civil penalty waiver request	$290

How to get more time: the extension process

Local Law 51 and its implementing rule both anticipate that some facade repair jobs genuinely need more time than 5 months, 8 months, or 2 years — a large or complex building, a landmarks review, a tough bid environment. The process is specific:

• The owner’s Registered Design Professional (RDP) — the engineer or architect of record — has to file the extension request, not the owner directly.
• Timing is narrow: the request must go in between 60 and 20 days before the milestone deadline it covers.
• For the 5-month and 8-month milestones, DOB can grant extensions in increments of up to 180 days at a time.
• For the 2-year completion milestone, DOB can grant a single, longer extension, with the duration based on the building’s size, the scope of necessary work, and the materials involved — supported by a signed contract showing the repair scope and timeline.
• If DOB objects to a request, a revised version is due within 14 days; after two rejected rounds, the request is denied outright and a new one (with a new fee) has to be filed.

Source: 1 RCNY § 102-07, subdivision (h). An owner who never requests an extension, or whose request is denied and not refiled, stays exposed to the fixed penalty on the original deadline.

When enforcement actually starts

Local Law 51 and Local Law 48 both became effective January 12, 2026. The implementing rule took effect August 13, 2026. But DOB has been clear that it’s phasing in enforcement rather than issuing penalties the day the rule landed. In an August 20, 2026 announcement, the Mayor’s Office and DOB said the department is “conducting outreach to property owners about the new requirements and expects to begin imposing penalties in early 2027.”

That’s a real but narrowing window. If your building’s shed went up on an initial permit issued on or after January 12, 2026, the 5-month and 8-month clocks may already be close to running out even though penalties aren’t being assessed yet — and once enforcement starts, DOB will be looking at whether the milestones were actually met, not just whether the shed is still standing.

What this means if your building has a shed up for facade repairs

If a FISP/Local Law 11 finding is why your shed went up, Local Law 51’s deadlines are running against your first shed permit right now, independent of your FISP filing deadline. The practical sequence that keeps a building ahead of both: get an engineer scoping and documenting the repair immediately so construction documents can be filed inside the 5-month window; get that permit application in and respond to DOB objections fast enough to clear the 8-month mark; and have a contractor mobilized — scaffold and shed sequencing, masonry and sealant crews, parapet and roofing work as the scope requires — so the 2-year completion deadline is realistic rather than aspirational.

Altius CM runs that sequence on FISP facade restoration work across NYC: scoping and engineering coordination, permit tracking, masonry and parapet repair, sealant and waterproofing, roofing, and shed/scaffold sequencing, with weekly progress logs and drone facade surveys to document where the work stands. See our scope of work approach and our full services list for how that fits together, and our Local Law 11 / FISP overview for the inspection side that often triggers the shed in the first place.

This is general information, not legal advice. Confirm your building’s specific shed permit issue date and milestone deadlines in DOB NOW: Build, since individual filing history determines exactly when your clocks started.

If your building has a sidewalk shed up and you’re not sure where you stand against the 5-month, 8-month, or 2-year clock, talk to us before a missed milestone becomes a penalty.
