A month-by-month guide to elevator inspections, boiler compliance, FISP cycles, LL152 gas piping, energy benchmarking, and all DOB filing deadlines. Never miss a critical inspection date again.
NYC building owners face a bewildering array of overlapping compliance deadlines. Elevator inspections, boiler certification, facade examination, gas piping surveys, energy benchmarking, and parapet observations all operate on different cycles: some annual, some multi-year. Missing even one deadline can result in thousands in fines, insurance complications, and liability exposure.
This calendar organizes every major 2026 inspection deadline month by month, so you can see at a glance what is due when, and plan your compliance strategy accordingly. Dates and penalties below were checked against the Department of Buildings rules and notices on November 9, 2026.
A typical NYC building may have four or five different compliance obligations running simultaneously on different schedules:
The CAT1 period runs January 1 to December 31, 2026, and every elevator needs a CAT1 test in the calendar year. The report is filed with DOB within 21 days of the test. Schedule early to avoid end-of-year bottlenecks. Budget 4-6 weeks for scheduling.
Low-pressure boilers need an annual inspection between January 1 and December 31, 2026, filed with DOB within 14 days of the inspection. Consecutive inspections must be at least six months apart. Early-year scheduling keeps the inspection clear of the next heating season.
If your tax block number ends in 4, 5, 6 or 9, your building is in Sub-cycle A. Its filing window opened February 21, 2025 and closes February 21, 2027. If you have not yet filed, plan your critical examination for 2026.
For buildings over 25,000 sq ft: begin gathering utility data (electric, natural gas, steam, water) for the 2025 calendar year. The benchmarking report is submitted to the City through ENERGY STAR Portfolio Manager by May 1, 2026. Start now to avoid last-minute scrambling.
Buildings whose tax block number ends in 0, 7 or 8 are in Sub-cycle B. Its filing window opens February 21, 2026 and closes February 21, 2028. There is time, but engaging your facade engineer early gives you the widest choice of inspection dates.
Buildings in community districts 4, 6, 8, 9 and 16 (in any borough) are due for their LL152 gas piping inspection by December 31, 2026. The inspection is done by a Licensed Master Plumber, and the GPS2 certification is filed with DOB within 60 days of the inspection. Spring scheduling leaves time for any corrections.
Local Law 126 requires annual parapet observations. March through September is optimal (better weather, good visibility, observer availability). Spring scheduling avoids the year-end rush and winter weather complications. Budget $445-$600 per building.
The periodic (visual) elevator inspection must be done in the same calendar year as the CAT1 test, at least three months apart from it, and filed within 14 days. April is a popular month because it leaves room for both before year-end. Expect 4-week scheduling lead time.
Sub-cycle A buildings (blocks ending in 4, 5, 6, 9) that have not yet filed should book their facade engineer this spring. The report is filed within 60 days of the critical examination, and the window closes February 21, 2027.
Buildings over 25,000 sq ft must submit 2025 energy benchmarking data to the City through ENERGY STAR Portfolio Manager by May 1. Missing it brings a $500 penalty, then another $500 for each quarter it remains unfiled (1 RCNY 103-06). Do not miss this date.
Buildings over 25,000 sq ft file their LL97 emissions report for the previous calendar year by May 1. Emissions over the building's limit are penalized at $268 per metric ton of CO2e.
Buildings over 50,000 sq ft whose tax block number ends in 6 must submit their Energy Efficiency Report (energy audit and retro-commissioning) by December 31, 2026. Starting by midyear leaves time for the field work. This is a 10-year cycle; do not confuse it with annual LL84 benchmarking.
By July, you should have completed or scheduled: boiler inspection, parapet observation, elevator CAT1, elevator periodic, and any LL152 inspections due in 2026. If you are behind on any of these, July is your chance to get back on track before the fall rush.
Buildings whose tax block number ends in 1, 2 or 3 are in Sub-cycle C. Its window opens February 21, 2027 and closes February 21, 2029. Owners of these buildings can line up an engineer now for a 2027 examination.
With heating season approaching, verify your boiler inspection is completed and the DOB filing is in. Any needed repairs from the inspection should be scheduled and completed during the warm months, before heating demand peaks.
August is your last calm month. The year ends with elevator CAT1 and periodic inspections, boiler inspections, LL152 gas piping (districts 4, 6, 8, 9, 16) and LL87 energy audits (blocks ending in 6), all due by December 31. FISP Sub-cycle A closes soon after, on February 21, 2027. Schedule remaining inspections in August or early September.
Sub-cycle A buildings (blocks ending in 4, 5, 6, 9) must file by February 21, 2027. Facade work is hard to do in winter, so a building that has not had its critical examination should book it this fall.
For community districts 4, 6, 8, 9 and 16: if your gas piping inspection is not yet done, schedule it now. The deadline is December 31, 2026, and the GPS2 certification is filed within 60 days of the inspection. Plumbers book up rapidly in Q4.
If you have not yet completed CAT1 or periodic inspections, September is your final chance to book without rushing. The CAT1 test must be performed by December 31. Budget 2-3 weeks for scheduling if you haven't already done so.
For buildings over 25,000 sq ft, the LL97 report covering 2026 emissions is due May 1, 2027. Reviewing your 2026 energy use now shows whether you are tracking above your limit while there is still time to act.
Heating season is active. Your boiler inspection should be complete and filed with DOB. Any repairs recommended during inspection should already be done. Confirm the filing appears on the DOB record for your building.
Check that each of these is done or booked: elevator CAT1 and periodic inspections, low-pressure boiler inspection, LL152 gas piping (community districts 4, 6, 8, 9, 16), and the LL87 Energy Efficiency Report (blocks ending in 6). Book anything still open now, while there is time before the holidays.
If your block ends in 4, 5, 6 or 9 and your Cycle 10 report is not filed, book the examination now. After the window closes, the penalty is $5,000 per year for failure to file, plus $1,000 per month for late filing (1 RCNY 103-04).
CAT1 (no-load) tests and periodic inspections must be performed by December 31, 2026, along with any CAT5 test that falls due. Reports are filed within 21 days of a CAT1 or CAT5 test and within 14 days of a periodic inspection. For commercial, mixed-use and buildings with more than two units, failure to file a CAT1 is $3,000 per elevator, and late filing is $150 per month up to $1,800 (1 RCNY 103-02).
The annual low-pressure boiler inspection must be performed by December 31, 2026 and filed within 14 days; the late filing period ends January 14, 2027. Failure to file is at least $1,000 per boiler, and late filing is $50 per month per boiler up to $600 (1 RCNY 103-01).
For buildings over 50,000 sq ft whose tax block number ends in 6: the Energy Efficiency Report is due December 31, 2026. Failure to submit an acceptable report may bring a $3,000 penalty in the first year and $5,000 for each additional year (1 RCNY 103-07).
For community districts 4, 6, 8, 9 and 16: the gas piping inspection is due by December 31, 2026, with the GPS2 certification filed within 60 days of the inspection. The penalty for failure to file is $5,000, or $1,500 for a three-family building (1 RCNY 103-10).
FISP (Facade Inspection Safety Program) applies to buildings taller than six stories and runs on a 5-year cycle. Cycle 10 is split into three sub-cycles, assigned by the last digit of the building's tax block number. Each sub-cycle has a two-year filing window (DOB service notice).
| Sub-cycle | Block Last Digit | Filing Window Opens | Filing Window Closes | Status in November 2026 |
|---|---|---|---|---|
| A | 4, 5, 6, 9 | February 21, 2025 | February 21, 2027 | Open; closes in about three months |
| B | 0, 7, 8 | February 21, 2026 | February 21, 2028 | Open |
| C | 1, 2, 3 | February 21, 2027 | February 21, 2029 | Not yet open |
Local Law 152 requires periodic inspection of gas piping in every building except one- and two-family homes. The 4-year cycle is fixed by community district (CD), and the schedule uses the district number in every borough. Each year's inspection is due December 31, and the GPS2 certification is filed with DOB within 60 days of the inspection (DOB schedule).
| Community Districts | Previous Cycle | Next Due (December 31) |
|---|---|---|
| 4, 6, 8, 9, 16 | 2022 | 2026 (this year), then 2030 |
| 11, 12, 14, 15, 17 (and any district not listed) | 2023 | 2027, then 2031 |
| 1, 3, 10 | 2024 | 2028 |
| 2, 5, 7, 13, 18 | 2025 | 2029 |
Local Law 87 requires buildings over 50,000 sq ft to submit an Energy Efficiency Report (an energy audit plus retro-commissioning) every 10 years. The year is set by the last digit of the tax block number (the "block" in your Borough-Block-Lot, or BBL): the report is due December 31 of the year whose last digit matches it.
If your building's tax block number ends in 6, your Energy Efficiency Report is due by December 31, 2026.
Examples: Block 1235 = digit 5 (was due 2025). Block 1236 = digit 6 (DUE 2026). Block 1246 = digit 6 (DUE 2026).
| Tax Block Last Digit | Status | Report Deadline | Next Cycle |
|---|---|---|---|
| 6 | DUE 2026 | December 31, 2026 | 2036 (10-year cycle) |
| 7 | Due 2027 | December 31, 2027 | 2037 |
| 5 | Was due 2025 | December 31, 2025 (past) | 2035 |
Elevator inspections in NYC are regulated by the Department of Buildings and operate on overlapping cycles keyed to the calendar year (January 1 to December 31). Understanding which inspections apply to your building is essential.
All buildings must complete:
Defects found in a test or inspection must be corrected within 90 days (hazardous conditions immediately), and the affirmation of correction is filed within 14 days of the correction. If your last CAT5 was in 2021, your next CAT5 is due in 2026. If your last CAT5 was in 2022, your next CAT5 is due in 2027.
List each compliance requirement for your building with the 2026 deadline. Columns: Service, Status (pending / scheduled / completed), Due Date, Provider, Cost, Filing Date. Update monthly. This becomes invaluable for buildings with multiple properties.
Elevator and boiler inspections can both happen on the same visit. Parapet observations fit with boiler inspections (both require roof access). Combining services reduces disruption, saves money, and ensures compliance across multiple requirements with a single site visit.
Enter your address and ZIP code into our free Compliance Assistant at insparisk.com/compliance-calculator. The tool identifies all 2026 deadlines specific to your building (FISP, LL152, LL87, etc.) based on your block number and community district. This beats manual block lookup every time.
Q4 (September-December) sees explosive demand for inspections. Inspectors book 4-6 weeks out starting in August. Schedule your inspections by July 31 to secure calendar slots. Late scheduling (November-December) limits availability and may force you into overtime or rush fees.
Reports need time to be written and filed. Do not book your inspection for the last week of December and expect everything to be done by December 31. Complete inspections 3-4 weeks before the deadline to allow for report generation and filing, and remember the filing windows: 21 days for elevator CAT1 and CAT5, 14 days for elevator periodic and boiler inspections, 60 days for LL152 GPS2 and FISP reports.
Mark your calendar now for:
Your FISP sub-cycle is set by the last digit of your NYC tax block number (the "block" in BBL: Borough-Block-Lot). You can find this on your DOF property tax bill, or enter your address in the Insparisk Compliance Assistant and it will return your block and FISP cycle status.
Each program has its own penalties. Examples from the DOB rules: failure to file a CAT1 elevator report is $3,000 per elevator in commercial, mixed-use and buildings with more than two units; failure to file a low-pressure boiler report is at least $1,000 per boiler; failure to file LL152 is $5,000 ($1,500 for a three-family building); and failure to file a FISP report is $5,000 per year plus $1,000 per month. A building that is out of compliance also carries more liability exposure if an incident occurs. If you have missed a deadline, get the inspection done and the filing in as soon as possible, since several penalties grow with each month.
FISP is a separate comprehensive facade assessment performed by a licensed PE or RA. It cannot be combined with boiler, elevator, or parapet inspections. However, you can coordinate the scheduling to happen in the same week, minimizing site disruption.
No. LL84 (annual, buildings over 25,000 sq ft) is a utility data submission due May 1. LL87 (every 10 years, buildings over 50,000 sq ft) is a detailed engineering audit and retro-commissioning, due December 31 of the year matching your tax block's last digit. If your block ends in 6, 2026 is your LL87 year and you may owe both.
The CAT1 test is required every calendar year, and the periodic inspection is required every calendar year as well. If your building's last CAT5 test was in 2021, your CAT5 is also due in 2026. Many owners schedule the CAT5 alongside that year's CAT1; your elevator inspection agency can confirm how they will be performed and filed for your equipment.
Parapet observations (Local Law 126) require a qualified observer but not necessarily a licensed PE. Many inspection firms have qualified observers on staff. Cost is typically $445-$600 per building. Insparisk offers parapet observations as standalone ($445) or bundled with boiler inspections ($795 for both).
Most inspectors accept bookings 2-3 months in advance. You can schedule your 2026 boiler, elevator, and parapet inspections as early as January 2026. Scheduling early (January-July) ensures better availability and avoids year-end crunch. Do not wait until November.
