Local Law 49 of 2025: Façade inspection interval changes

Amends the statutory framework for exterior-wall inspection intervals and requires a DOB study of façade inspection timing.

New York City jurisdiction · Sources checked September 15, 2026. Law numbers repeat by year. These educational summaries are not legal advice or a complete compliance checklist. Later amendments, agency rules, building characteristics, and effective dates determine the requirements for a particular property. Use the linked City sources to confirm current obligations.

Why it matters

The inspection amendment is scheduled to take effect October 1, 2026. It provides for intervals established by rule between six and twelve years and changes the initial examination provision. As of this reference review, do not treat that future framework as permission to disregard an existing filing deadline.

In practice

A project example

An owner retains the current façade inspection appointment while asking the qualified professional to confirm how DOB’s implementing rules and transition affect the building’s next cycle.
