Most New York City compliance obligations announce themselves. A filing is due, a portal shows a deadline, an agency sends a notice, and a fee concentrates the mind.
Several of the most consequential ones do not. No filing, no portal, no notice — just a date in a code appendix and a building that either did the work or did not.
This is every recurring obligation with a fixed date in one place, plus the triggered ones that have no date at all.
Dates, thresholds and requirements change. This states the position as of August 2026, and each linked page carries its own sources and caveats. Confirm anything you are relying on with the relevant agency.

Dated obligations landing soon
| Date | What |
|---|---|
| 8 September 2026 | NYC Bin full enforcement begins for properties with 1–9 residential units |
| 27 September 2026 | Certification of No Harassment pilot authorization runs through this date — confirm current status with HPD |
| 1 January 2027 | Elevator single-plunger brake and door restrictor compliance |
Deadlines that have already passed
Worth listing, because a building that missed one is not approaching a deadline — it is overdue.
- 9 August 2025 — XRF lead-based paint testing of dwelling units under Local Law 31 of 2020, and of common areas under Local Law 111 of 2023.
- 1 January 2020 — elevator door lock monitoring. A building that has not done this is roughly six years late, and it should be resolved ahead of anything scheduled for 2027.
Cyclical, not calendar-fixed
These recur on cycles set by building type, equipment, or community district rather than by a citywide date. Each has its own page with the specifics:
- Boiler inspection and filing
- Elevator inspections — Category 1 and Category 5
- FISP / Local Law 11 facade cycles — buildings over six stories
- Local Law 152 gas piping inspections — by community district
- Backflow prevention testing — every 12 months, filed with DEP within 30 days
- HPD property registration — annual
- DHCR rent registration — annual, for stabilized units
Triggered, with no date until something happens
Before a permit will issue:
- ACP-5 asbestos filing — permitted work in buildings built before 1 April 1987
- Certification of No Harassment — buildings on HPD's list
- Sprinkler alteration trigger — pre-1968 non-sprinklered R-2 buildings, alterations reaching 75% of units
Clocks that start when something arrives:
- ~4 weeks — a Commissioner's Order to Abate to the rat mitigation compliance inspection
- 4 months — Alternative Enforcement Program selection to discharge
- 30 days — backflow test result to DEP
Ongoing, no date:
- Composting and organics separation — mandatory citywide, fines resumed 1 January 2026
- Fire safety notices and preparedness materials — posted and distributed, not filed
- E-bike charging rules — including the shared-space threshold at six devices
The seven weeks that cause the trouble
Look at the annual table again and notice where it clusters.
31 December, 31 December, 15 January, 15 February. Four obligations, four agencies — DOB, HPD, DOHMH, HPD again — inside seven weeks, straddling the holidays and the worst weather of the year.
Almost none of them require year-end performance. They require annual performance with a year-end or early-year deadline.
An owner who runs the parapet observation and the Local Law 55 inspection in September or October, and books the water tank inspection in the spring, turns four winter deadlines into four filing dates. An owner who does not spends January trying to book licensed professionals for rooftop work, alongside every other building that also left it late.
That is the single most useful scheduling insight across this entire calendar, and it costs nothing to act on.
Which of these actually apply to you
Knowing what you are not subject to is as valuable as knowing what you are.
Keyed to size or equipment — and therefore not universal:
- Energy label — over 25,000 square feet
- FISP — more than six stories
- Water tank — only if the building has one
- Elevator items — only if there is an elevator
- Backflow — turns on plumbing: treated boilers, roof tanks, multiple service lines
Reaching almost everything:
- Parapet observation — any height, excepting detached 1–2 family. The buildings most confidently exempt from FISP are precisely the ones caught here.
- Local Law 55 — three units. No building-age cutoff, no occupancy trigger.
- Composting — citywide.
Why the invisible ones lapse
The parapet observation is not filed with anyone. The Local Law 55 inspection is not filed. Fire safety notices are posted, not submitted.
Where there is no portal, no fee and no chasing notice, the obligation exists entirely in whether somebody at the building is keeping a calendar. That is why these are the ones that go missing in a self-managed building — not because anyone decided to skip them, but because everybody assumed somebody else had it and nothing arrived to prove otherwise.
The fix is unglamorous: one calendar, one person responsible, and confirmation recorded rather than assumed.
Where a managing agent carries this
Running this calendar — including the items nobody sends a reminder for, booking licensed inspections early enough to avoid the winter crunch, keeping the records where the building can produce them, and telling an owner or board that it was actually done — is the core of apartment building management and legal and regulatory compliance.
If you cannot say when your building's last parapet observation was, or whether this year's filings were made, schedule a consultation or call 718-568-9278.
This calendar is general information, not legal advice. Dates, thresholds and requirements change, and applicability depends on your specific building. Confirm with the relevant agency — DOB, HPD, DOHMH, DEP, DOF, DSNY or FDNY — before relying on any entry.
