Local Law 11 / FISP in Brooklyn
Brooklyn's FISP-obligated buildings span a wider range of construction eras than any other borough: landmarked brownstone and rowhouse blocks sit alongside a growing number of mid- and high-rise developments concentrated in Downtown Brooklyn, Williamsburg, and DUMBO.
Filing Windows That Apply in Brooklyn
Cycle 10 sub-cycle assignment is based on the last digit of a building's tax block number, looked up through NYC ACRIS or DOB BIS — the same citywide rule applies in Brooklyn as in every other borough.
| Sub-Cycle | Block Number (Last Digit) | Filing Window |
|---|---|---|
| 10A | 4, 5, 6, or 9 | Feb 21, 2025 – Feb 21, 2027 |
| 10B | 0, 7, or 8 | Feb 21, 2026 – Feb 21, 2028 |
| 10C | 1, 2, or 3 | Feb 21, 2027 – Feb 21, 2029 |
Buildings that received their first temporary certificate of occupancy after Cycle 9 began may be filing under FISP for the first time in Cycle 10. First-time filers follow the same sub-cycle assignment, based on block number, as previously-filed buildings.
Brooklyn Building Stock Notes
Older FISP-obligated buildings in Brooklyn Heights, Park Slope, and Fort Greene generally use masonry facades comparable to older Manhattan stock, while a large share of the borough's taller buildings were constructed after 2005 with precast concrete, brick veneer, or curtain wall systems. Construction date does not affect FISP obligation: any building over six stories is subject to the program once it reaches its first inspection threshold, regardless of when it was built.

Brooklyn-Specific Questions
Are newer Brooklyn buildings exempt from FISP?
No. Any building over six stories is subject to FISP regardless of construction date. A newer building becomes subject to its first inspection cycle once it reaches roughly five years from its first temporary certificate of occupancy.
Does converting or enlarging a building change its filing requirement?
Story count and DOB building classification determine FISP obligation, not the building's original use or construction type. A block number lookup through DOB BIS confirms the applicable sub-cycle.
Why do DOB violation counts vary so much between Brooklyn blocks?
Filing compliance depends on individual building ownership, age, and prior-cycle history rather than neighborhood as a whole; each building's DOB record reflects its own inspection and filing history.
Who is responsible for filing on a Brooklyn co-op or condo?
The building owner of record — typically the cooperative corporation for a co-op, or the condominium board for a condo — acting through a retained QEWI.
