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.

What a realistic November looks like

Work backwards. The certification has to be filed in DOB NOW by 31 December. Before that the licensed master plumber has to get you the inspection report and the signed certification, which the rule gives them up to thirty days to do, §103-10(d)(1). Before that the inspection has to happen. Before that the plumber has to notify DOB, at least two days ahead, §103-10(a)(6).

So an inspection booked for 15 December is not a 15 December problem. If the plumber takes the full thirty days on the paperwork you are filing in mid-January, past the penalty date. Most plumbers turn it round faster than that. You are relying on them to.

And if conditions requiring correction turn up, that is a separate clock again with its own deadline and its own filing.

Missed it

File anyway, and file now rather than waiting for the paperwork to find you. The penalty under §103-10(f) is $1,500 for a 3-family building and $5,000 for everything else. It does not grow with time, and filing late is better than not filing, because an unresolved violation needs both the payment and the certification before it clears.

DOB's own notice for the previous sub-cycle records Notices of Violation going out in January 2026 for a deadline that fell at the end of 2024. If you are late you probably have some months before anything arrives. Use them.

There are waiver grounds in §103-10(h), added in January 2026: new ownership, government ownership, bankruptcy, a state of emergency, conversion to or misclassification as R-3, a demolished building, a sealed or vacated building, no gas piping, no active gas service, and gas work already in progress. Challenges go in within 30 days of the violation date.
