LL97 Covered Buildings List FAQs

A BBL (borough, block and lot) is a 10-digit identifier provided to the Department of Buildings (DOB) by the Department of Finance (DOF), to identify the tax lots containing buildings that meet the square footage threshold of LL97. A BBL can include one building or multiple buildings. Note that LL97 compliance requirements must be demonstrated at the building level (as designated by a Building Identification Number, or BIN) rather than BBL level.

If you believe your building is erroneously listed on the LL97 CBL due to the square footage of your building, contact the NYC Department of Finance at sustainablebuildings@finance.nyc.gov. Please include the following in the email:

• borough, block, and lot number of the building
• contact information: name, email address and/or telephone number
• explanation of your dispute and RDP certification if applicable

Once you receive confirmation related to your dispute from the NYC Department of Finance you can submit a “01. Covered Buildings List (CBL) Disputes” ticket on BEAM. For more information on submitting CBL Disputes please see the CBL Disputes User Guide.

Yes. The 2025 LL97 CBL displayed only covered buildings for Local Law 97. The new 2026 CBL displays covered buildings for all of the DOB Sustainability Laws (LL84, LL87, LL88 and LL97) in a single document. You can find a building’s LL97 compliance pathway in columns C and D of the CBL.

The 2025 LL97 CBL listed all compliance pathways associated with a tax lot (BBL), without identifying which pathway applied to each specific building.  The 2026 LL97 CBL lists compliance pathways that apply to a specific building (BIN). Where DOB has not received BIN-specific information showing that a specific pathway applies to a building (either through partner agency data or a CBL dispute), the building will appear under Compliance Pathway 0 (Article 320, beginning 2024).

Disputes approved and processed after February 2026 may not be reflected in the 2026 LL97 CBL. However, the BEAM platform will be updated to include the outcome of these approved disputes. Confirmation of the outcome of the dispute via BEAM guarantees that your building should comply in accordance with the outcome of the dispute in 2025 and 2026.

When a building meets the definition of multiple compliance pathways, the owner must demonstrate compliance with the highest tiered compliance path. The tiers are listed below from lowest to highest:

1. Article 320, beginning 2024: ‘Compliance Pathway 0’ (CP0)
2. Article 320, beginning 2026: ‘Compliance Pathway 1’ (CP1)
3. Article 320, beginning 2035: ‘Compliance Pathway 2’ (CP2)
4. Article 321: ‘Compliance Pathway 3’ (CP3)
5. City Buildings/NYCHA: ‘Compliance Pathway 4’ (CP4)

For example, if a building meets the definition of BOTH CP0 and CP2, the higher tier is CP2 and the building should demonstrate compliance with CP2. If the data reflected in the LL97 CBL is not correct, the owner must notify DOB by submitting Ticket #1 in the LL97 Reporting Portal (BEAM).

To update a building record, submit Ticket #1, "Covered Buildings List (CBL) Disputes" ticket in the LL97 Reporting Portal (BEAM) for DOB review and approval. Please consult the CBL Dispute User Guide prior to submitting your dispute.

There may be multiple BINs on the BBL because there are multiple buildings on the BBL

LL97 compliance, including the submission of reports and assessment of any penalties, is at the level of an individual building (as designated by a Building Identification Number, or BIN). A BBL (borough, block and lot) can include one building or multiple buildings.

Each individual building has its own compliance pathway, specific to the legal status of that building. The CBL sets out DOB’s preliminary data for the compliance pathways indicated for that building. Each building must submit a compliance report in accordance with the compliance pathway that applies to the specific building regardless of the compliance pathway that another building on the same BBL may be subject to.

Generally, the LL97 Reporting Portal (BEAM) has been set up using the building information that appears on the CBL. The BBL has been provided by DOF, and the BINs are associated with that BBL in city records. Building owners (and/or their service providers) should submit a CBL dispute ticket in BEAM if the BBL and/or the BIN used to identify a building on the CBL should be updated.

If you have an active CBL Dispute regarding your compliance pathway, you should submit your report based on the compliance pathway you believe is correct, as asserted in your dispute. If you believe your building does not have to comply in a given filing year, you should not comply for this building until the dispute is resolved. For calendar year 2024, (filing year 2025), no penalty will be issued for failure to report if you’ve submitted a report based on the above and your CBL Dispute is denied. You will have until May 1, 2026 to submit the correct report relating to calendar year 2024 (filing year 2025), in addition to any report required for calendar year 2025 (filing year 2026).

If you believe your building is a “garden style apartment” as described in exception #2 of the definition “covered building” in § 28-320.1 of the NYC Administrative Code or exception #1 of the definition of “covered building” in § 28-321.1 of the NYC Administrative Code, notify DOB by submitting Ticket #1 in the LL97 Reporting Portal (BEAM).

In the Ticket 1 submission, please identify any prior filings with DOB that will provide evidence of the HVAC and hot water heating systems in the buildings meeting the definition referenced above. Acceptable prior filings include and are not limited to LL87 Retro-commissioning report, Equipment Use Permit/Certificate of Compliance for HVAC or hot water heating system equipment, Plan/Work Application filed and approved by DOB for such system.

If no prior filings have been submitted to DOB, DOB will follow up with next steps for verification.

If you believe that the dwelling units in your building are rent regulated, and this is not reflected on the CBL, notify DOB by submitting Ticket #1 in the LL97 Reporting Portal (BEAM). Please consult the CBL Dispute User Guide prior to submitting your dispute.

The following supporting documentation must be uploaded on your CBL Dispute Ticket:

• DHCR Certified Annual Registration Summary from the current or previous calendar year, showing number of units under rent regulation. Owners can request records here: orarecords@hcr.ny.gov
• If the number of rent controlled units determines the building’s compliance pathway, please supply a signed letter from a lawyer, confirming that of the dwelling units in the building:
  • 1 or more units but less than 35% of the dwelling units are rent regulated (rent controlled or rent stabilized). OR
  • over 35% of the dwelling units in the building are rent regulated (rent controlled or rent stabilized). that of the dwelling units in the building over 35% are rent regulated (rent controlled or rent stabilized).

LL97 defines “house of worship” as a building whose main use or dominant occupancy is classified as occupancy group A-3 of 2022 NYC BC or equivalent to A-3 from prior codes, i.e., religious house of worship. This means that greater than 50% of the building is used as assembly space for religious worship purposes. Such buildings are subject to Article 321 “CP3.”

If your building is a House of Worship, notify DOB by submitting Ticket #1 in the LL97 Reporting Portal (BEAM). Please submit the ‘House of Worship Verification Form’, and ‘House of Worship Use Verification Sheet’.

Building that received a House of Wordship Verification from the Department:

For buildings that have already submitted ‘House of Worship Verification Form’, and ‘House of Worship Use Verification Sheet’ to GHGemissions@buildings.nyc.gov or BEAM and received a confirmation email from the Department, building owners are required to submit Ticket 05. LL97 Compliance Report (Article 321) to demonstrate compliance with LL97.

The 421-a Tax Incentive alone is not enough to determine a building’s compliance path under LL97. While in receipt of 421-A tax benefits, the rental units in a building will likely be rent stabilized, but following expiry of the tax benefits these units may be de-stabilized and the building may no longer be subject to Article 321. A building must participate in one of the programs listed on the CBL Matrix to qualify for an alternative compliance path under the law.

Disputes approved after December 22, 2025 will not be reflected in the 2026 LL97 CBL. However, the 2026 LL97 CBL will be updated to include the outcome of these approved disputes.

If you need to update the owner information on your building – for example, where a co-op shareholder is receiving communications as if that individual is the owner of entire co-op, you can share contact information for the appropriate person with DOB at BEAM_LL97@buildings.nyc.gov.
