NYC Local Law 11 Explained

If you own or manage a multi-story building in New York City, you’ve almost certainly heard of Local Law 11. It’s the source of the ubiquitous sidewalk sheds that line so many Manhattan streets, the basis for inspection notices that appear in building mailboxes, and the regulatory framework behind millions of dollars of facade repair work carried out on NYC buildings every year. Here’s what building owners actually need to know.

What Is Local Law 11?

Local Law 11 of 1998 is the New York City law that established mandatory facade inspections for buildings six stories and taller. It was enacted following a 1979 tragedy in which a Barnard College student was killed by falling masonry from a Columbia University building — a preventable failure that highlighted the need for systematic oversight of New York City’s aging building facades.

The law requires that all covered buildings have their exterior walls and appurtenances inspected by a qualified professional every five years. It created an ongoing, cyclical inspection program that applies to thousands of buildings across all five boroughs.

Formally, the program is called the Facade Inspection Safety Program (FISP), administered by the NYC Department of Buildings under 1 RCNY 103-04. “Local Law 11” and “FISP” are used interchangeably in practice.

Which Buildings Does Local Law 11 Apply To?

The law applies to:

• Buildings six or more stories above grade
• Located anywhere in New York City (all five boroughs)

The threshold is based on building height as measured in stories, not height in feet. The law applies regardless of building age, construction type, or ownership structure — residential, commercial, mixed-use, institutional buildings all fall under FISP if they meet the height requirement.

Notable exemptions: Buildings fewer than six stories are not covered, even if they are on a slope where one elevation might appear taller. New buildings have a grace period before their first required inspection.

What Does the Law Require?

Under Local Law 11 / FISP, covered building owners must:

1. Hire a Qualified Exterior Wall Inspector (QEWI) — A licensed professional engineer (PE) or registered architect (RA) with specific exterior wall inspection credentials
2. Conduct a close-up inspection — Close physical access to all exterior facade surfaces, not just ground-level visual inspection
3. File a technical report with the DOB — The report classifies each facade elevation as Safe, SWARMP, or Unsafe
4. Take required corrective action — Based on the classification, building owners may need to establish protective measures immediately (Unsafe), complete repairs on a timeline (SWARMP), or do nothing until the next cycle (Safe)
5. File every five years — Inspections must repeat on a five-year cycle, within a sub-cycle window determined by the building’s block number

The FISP Classification System

Every FISP inspection results in one of three classifications:

Safe — No hazardous conditions found. No repairs required for this cycle. The inspection report is filed and the building is clear until the next five-year cycle.

SWARMP (Safe With a Repair and Monitoring Program) — Conditions present that are not immediately hazardous but require repair or monitoring. Building owners must develop and execute a repair plan and file an amended report when repairs are complete.

Unsafe — Immediate hazard to public safety. Protective measures (sidewalk shed or safety netting) must be in place within 24 hours. Repairs must be completed and the building re-inspected within the DOB-mandated timeline.

What Are the Penalties for Non-Compliance?

Civil penalties for missing FISP filing deadlines begin accruing from the deadline date. Unsafe designations that are not addressed promptly carry additional penalties. These penalties compound monthly and ultimately become liens on the property.

Beyond financial penalties, outstanding Unsafe designations create liability exposure for building owners and can complicate property sales and refinancing transactions.

How FISP Cycles Work

Inspections happen on a five-year cycle, but not all buildings have the same deadline within a given cycle. The DOB staggers deadlines by block number, assigning each building to a sub-cycle group. This distributes the inspection workload across the five-year period.

Cycle 10 is the current inspection cycle. Sub-cycle filing windows are opening on a rolling schedule from 2025 through 2029. If your building has not already identified its Cycle 10 sub-cycle deadline, do so now — QEWIs book out months in advance as deadlines approach.

Getting Your Building Into Compliance

The process:

1. Identify your sub-cycle deadline through DOB BIS or your managing agent
2. Engage a QEWI for inspection — allow 3-4 months before your deadline
3. Conduct the inspection with required close-up access
4. Address any Unsafe conditions immediately; begin SWARMP repair planning
5. File the inspection report through DOB NOW: Safety before your deadline
