Sub-Cycles 10A and 10B are both active now. If your building falls into either window, the clock is already running.
Cycle 10 Filing Deadlines
Your building's deadline is determined by the last digit of your NYC DOB Block Number. Here are the three sub-cycles:
| Sub-Cycle | Block # Ends In | Filing Window | Status |
|---|---|---|---|
| 10A | 4, 5, 6, or 9 | Feb 21, 2025 – Feb 21, 2027 | Active Now |
| 10B | 0, 7, or 8 | Feb 21, 2026 – Feb 21, 2028 | Active Now |
| 10C | 1, 2, or 3 | Feb 21, 2027 – Feb 21, 2029 | Upcoming |
What Owners Should Confirm in Cycle 10
Before filing, owners and their QEWI should confirm how current DOB guidance applies to their building:
1. Cavity Wall Probe Requirements
DOB technical guidance introduced cavity wall probe expectations in Cycle 9 and ties continuing probe requirements to later odd-numbered cycles and applicable building conditions. For Cycle 10, owners should have the QEWI verify whether prior probes, construction type, observed conditions, or any DOB direction require additional probes before filing.
2. Annual Parapet Inspections
Beginning in 2024, buildings with parapets fronting the public right-of-way must have annual parapet observations regardless of height, with limited exceptions. The report is supplied to the owner and kept for at least six years; no ordinary DOB submission is required.
3. Digital-Only Filing
All reports must be filed through the DOB NOW Safety portal. Paper submissions are no longer accepted under any circumstances. Both the QEWI and the building owner must be registered in the DOB NOW system before filing.
What Happens If You Missed Cycle 9
Buildings marked as "No Report Filed" (NRF) from Cycle 9 are not automatically cleared when Cycle 10 begins. You must submit a Sub-cycle Override Request to file immediately. If your building has cavity wall construction, investigative probes are mandatory as part of the late submission.
Civil penalties for non-compliance are now publicly visible in DOB NOW — meaning prospective buyers, lenders, board members, and insurance companies can see them instantly.
Why Starting Early Matters
The full FISP process — from hiring a QEWI through DOB filing — typically takes 3 to 6 months:
- QEWI selection and contracting: 2-4 weeks
- Access coordination (scaffold, rope, adjacent buildings): 2-8 weeks
- Field inspection and probes: 1-3 days
- Report preparation: 2-4 weeks
- DOB filing and processing: 1-2 weeks
Buildings that wait until the final year of their window frequently run out of time. Access agreements with adjacent property owners alone can take months to negotiate. Start early.
How to Find Your Block Number
Log into the DOB NOW Public Portal at nyc.gov/dobNOW and search your property address. Your block number appears in the building's registration details. The last digit determines your sub-cycle.
