LL152 due date lookup/Who is exempt from Local Law 152
The only exemption in the rule is occupancy group R-3, which in practice means one and two-family homes. A three-family building is not exempt. Buildings with no gas piping, and buildings with piping but no gas service, are excused from the inspection but still have to file something with DOB.
Paste a list of addresses or BBLs and get each building's community district, its sub-cycle, and the dates that lead up to its deadline, read from DOB's own covered-buildings list.
Open the due date lookup§103-10(a)(1) requires inspection of all building gas piping systems “except for gas piping systems in buildings classified in occupancy group R-3 in Section 310.1.3 of the Building Code”.
That is the whole exemption. The phrase “one- and two-family homes” does not appear in the rule. It is DOB's plain-English gloss, and it is accurate as far as it goes, but people read it as a size rule and it is not.
The three-family trap. A three-family building is not R-3 and is not exempt. It is covered, and it is the one building type with a reduced penalty: $1,500 rather than $5,000 under §103-10(f)(1).
The reduced penalty is the giveaway. The rule would not set a penalty for three-family buildings if three-family buildings were exempt. Several vendor pages tell three-family owners they are in the clear. They are not, and it is a $1,500 mistake.
In DOB's own data these are classes C0, walk-up apartments with three families, and S3, a primary three-family with a store or office. Both appear on the covered-buildings list.
DOB publishes a list of Department of Finance building classification codes it treats as exempt: A0 through A9, B1, B2, B3, B9, CM, M3 with two or fewer permanent dwelling units, M4 with twenty or fewer occupants, N2, S0, S1, S2, and V.
This list is DOB guidance, not rule text. It is useful, and it is what DOB works from, but the operative test in the rule is the occupancy group. If your building carries a classification that does not match how it is actually used, that is worth sorting out with DOB rather than relying on the code.
DOB ran an Exempt Building Notification process for exactly this problem, for one and two-family homes carrying an incorrect classification. That deadline was 30 April 2026 and has passed.
A building with no gas piping system at all does not need the inspection, but the owner has to submit a certification saying so, signed by a utility company, a registered design professional, or a licensed master plumber or someone under an LMP's direct and continuing supervision. §103-10(a)(2).
The rule then says something helpful: “Such statements need only be submitted once.” So this is a one-off, not a per-cycle chore.
Being straight about a wrinkle: that sentence sits directly above a list of due dates that recur “every fourth calendar year thereafter”, which read literally pulls the other way. DOB's guidance resolves it as file once, no further action. We think that is right. We are telling you it is a resolution rather than something the text states cleanly, because if your situation is unusual you should know the ground is slightly soft.
This filing carries a fee, and it is not the $35 one. See the note below.
A building that has gas piping, is not currently supplied with gas, has no appliance connected, and complies with Admin Code §28-318.3.5 does not need the inspection. §103-10(a)(3). Same due dates as the no-piping filing, and its own fee.
Local Law 142 of 2025 tightened what the utility statement has to say. It now needs a certification that the building no longer receives gas service, and confirmation that the building is fully deactivated from service.
Note that §103-10(a)(3) carries no “need only be submitted once” sentence. The no-piping exemption has that sentence. The no-service one does not.
If you later want gas turned back on, §28-318.3.6 applies: a certificate of approval of gas installation and full inspection compliance before service resumes, wherever your building sits in the cycle.
Fees for these two filings. DOB's fee rule at 1 RCNY §101-03 lists a filing fee for the certification of no gas piping system, and a separate, higher one for the documentation regarding no gas service. Both are materially more than the $35 inspection certification. We are not printing the two figures here until we have had a human read the fee table in the PDF directly, because we pulled them through an automated reader and a misread row in a fee table is exactly the kind of error this site exists to avoid. Check the rule, or ask DOB, before you budget.
A new building's first inspection happens “during the tenth year after the Department has issued a certificate of occupancy”. §103-10(a)(5). After that it rejoins its district's normal four-year lane.
A new building means one with a temporary, interim or final certificate of occupancy issued on or after 6 December 2016. A TCO starts the clock. Several vendor pages say final CO only, which would give some buildings years they do not have.
No. The exemption in 1 RCNY §103-10(a)(1) is occupancy group R-3, which covers one and two-family homes. A three-family building is covered, and it draws a reduced civil penalty of $1,500 rather than $5,000 under §103-10(f)(1).
Buildings classified in occupancy group R-3, which in practice means one and two-family homes. Buildings with no gas piping and buildings with piping but no gas service are excused from the inspection but must file a certification with DOB instead.
Yes. You file a certification of no gas piping system, signed by a utility company, a registered design professional or a licensed master plumber. The rule says such statements need only be submitted once. There is a filing fee.
§103-10(a)(2) says such statements need only be submitted once, and DOB's guidance says no further action is necessary. The same paragraph lists due dates that recur every fourth year, so the text is not perfectly clean, but file once is the working answer.
During the tenth year after DOB issued its certificate of occupancy, where the CO is a temporary, interim or final CO issued on or after 6 December 2016. §103-10(a)(5).
