Loading DOB’s covered-buildings list…
Our team at 02Launch.com builds AI into the workflows your managers already run. We made this page because DOB publishes the covered-buildings list as a spreadsheet, and matching a managed portfolio against it by hand is a day’s work.

Local Law 152 of 2016 requires the gas piping system in most New York City buildings to be inspected at least once every four years. The implementing rule is 1 RCNY §103-10. Which year your building falls in is set by its community district, not by its size, age or borough.
A licensed master plumber inspects the exposed gas piping, gives you a report and a signed certification within thirty days, and you file that certification with DOB within sixty days. Since 27 July 2026 the filing happens in DOB NOW: Safety and costs $35.
One and two-family homes are exempt, because the exemption in the rule is occupancy group R-3. A three-family building is not exempt.
| 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 |
Building counts are ours. DOB publishes the covered-buildings list as a spreadsheet of 279,810 rows and does not publish the totals, so we indexed it and counted. Source file dated 27 July 2026.
Community district numbers repeat across boroughs, so Manhattan CD 6, Brooklyn CD 6 and Queens CD 6 are all in the same sub-cycle. If you do not know your district, the lookup above will find it from the address.
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.
This page reads DOB's own covered-buildings list and returns the due date DOB holds for the address you paste. It is not a lookup table someone typed out. It is an index built over the spreadsheet DOB publishes, 279,810 rows, rebuilt when DOB updates it.
Where DOB's community district for a building disagrees with the City Planning district, the results flag it rather than quietly picking one, because that disagreement can move the deadline by a year.
Nothing you paste is stored. The page reads up to 250 lines at a time and forgets them when the tab closes. There is no login and no account.
Four claims turn up constantly and none of them survive a read of the rule.
“You cannot inspect more than 60 days before the due date.” No such provision exists. We searched the full text twice.
“Two business days' notice to DOB.” §103-10(a)(6) says two days. Not business days. And the notice is the plumber's duty, not the owner's.
“The penalty is $5,000.” It is $1,500 for a 3-family building and $5,000 for everything else, and has been since December 2024.
“The extension is one-time by law.” DOB administers it that way, and you should plan on one, but §103-10(d)(6) does not say so and neither does the statute.
Local Law 152 of 2016 requires periodic inspection of the gas piping system in most New York City buildings, on a four-year cycle set by community district. The implementing rule is 1 RCNY §103-10. Buildings in occupancy group R-3, which means one and two-family homes, are exempt.
It depends on your community district. Districts 4, 6, 8, 9 and 16 are due 31 December 2026. Districts 11, 12, 14, 15 and 17, plus any district not otherwise listed, are due 31 December 2027. Districts 1, 3 and 10 are due 31 December 2028. Districts 2, 5, 7, 13 and 18 are due 31 December 2029. Paste your addresses into the lookup above and it will tell you.
You do. The licensed master plumber signs and seals the certification and gives it to you within thirty days of the inspection, and the owner files it with DOB within sixty days. §103-10(d)(1) and (d)(2).
$1,500 for a 3-family building and $5,000 for all other buildings, under §103-10(f). DOB's own guidance page still prints a flat $5,000 and omits the lower tier.
No. The exemption is occupancy group R-3, which covers one and two-family homes. A three-family building is covered, and it is the building type that draws the reduced $1,500 penalty.
Yes, $35 since 27 July 2026. There was no filing fee before 2026, which is why a number of older pages say filing is free.
Yes. Nothing in §103-10 restricts how early in the cycle year an inspection may happen, and DOB's own schedule prints each sub-cycle as a full calendar year.
