Local Law 152 due dates for 2027

The catch-all nobody mentions

Sub-cycle D is not just those five districts. The rule reads: gas piping systems shall be inspected in “community districts 11, 12, 14, 15, and 17 and in any community district not specified in this paragraph in all boroughs”. §103-10(a)(4)(iv).

So if your district is not named in the 2024, 2025 or 2026 lanes, it falls here. An unlisted district is not an exempt district. Every competitor page we checked lists the five numbers and stops.

The full four-year schedule

Community districts are the same in every borough. Building counts are from DOB's covered-buildings list, 279,810 rows dated 27 July 2026.

Sub-cycle	Community districts	Inspection years	Buildings
A	1, 3 and 10	2024, 2028, 2032	71,689
B	2, 5, 7, 13 and 18	2025, 2029, 2033	77,475
C	4, 6, 8, 9 and 16	2026, 2030, 2034	68,620
D	11, 12, 14, 15 and 17	2027, 2031, 2035	62,026

Counts are ours. We built an index over DOB's covered-buildings spreadsheet, 279,810 rows, and counted the buildings in each sub-cycle. DOB publishes the list but not the totals.

Two deadlines, not one

Almost every page about Local Law 152 talks about a single deadline. There are two, they are triggered by different things, and missing them costs you different things.

The cycle deadline. Your building has to be inspected by 31 December of its year. §103-10(a)(4) sets the year by community district. §103-10(f) is the civil penalty for not having the certification in by that date: $1,500 for a 3-family building, $5,000 for everything else.

The sixty-day clock. Once the inspection happens, the owner has sixty days from the inspection date to file the certification. §103-10(d)(2). File on day sixty-one and the rule says the filing “will not satisfy the requirement of this paragraph” and “will require a new inspection”. Not a fine. A new inspection, paid for again.

The two interact badly at the end of the year. Sixty days from a 1 December inspection is the end of January, but the penalty under (f) has already attached on 31 December. So the practical window is whichever is shorter. Inspect on 1 December and you have thirty days to file, not sixty. Inspect on the 20th and you have eleven.

This is the single most common way a building that did everything right still ends up with a violation. The plumber came. The work got done. The paperwork sat on someone's desk over the holidays.

You can inspect any time in the year

There is no rule against inspecting early. We looked, twice, through the full text of §103-10. Nothing restricts how early in the cycle year an inspection may be performed. No “not more than 60 days before”, no “no earlier than”, nothing.

Several vendor pages say otherwise. DOB's own schedule table contradicts them: it prints each sub-cycle as a full calendar year window, 1 January to 31 December. An inspection on 2 January 2027 is compliant.

Book early anyway. Not because the rule says so, but because sixty thousand buildings are chasing the same licensed master plumbers in the same twelve months, and the ones who leave it to November are the ones who discover the sixty-day clock the hard way.

What happens on 1 January 2028

Nothing automatic. DOB issues Notices of Violation in batches after a sub-cycle closes, not on the stroke of midnight. For Sub-cycle A, which closed at the end of 2024, DOB's own service notice records that violations went out in January 2026, roughly a year later.

That lag is not a grace period. The penalty attaches on the deadline. The paperwork arrives when it arrives, and it arrives with a 30-day window to challenge it or request a waiver, filed in DOB NOW.
