Does Local Law 97 apply to your building?

Check the size thresholds, tax-lot and condominium grouping, individual building identity and compliance pathway using DOB’s current records.

Check all three coverage categories

  • A building exceeding 25,000 gross square feet.
  • Two or more buildings on the same tax lot exceeding 50,000 gross square feet together.
  • Two or more condominium buildings governed by the same board of managers exceeding 50,000 gross square feet together.

DOB uses Department of Finance floor-area records for coverage. A building below the individual threshold can still be included through a qualifying group. A threshold alone does not resolve exceptions or a compliance pathway.

Use the current list, then verify its record

DOB’s filing-year 2026 covered-buildings list reflects its March 2026 records and is provided for reference. Owners must verify their building’s characteristics and pathway. The presence or absence of an entry does not remove legal obligations.

If the identity, area or pathway is incorrect, follow DOB’s covered-buildings-list dispute process in BEAM. An owner-approved change may appear in BEAM before it appears in a downloaded list. BuildingFi cannot resolve a DOB dispute or certify an exemption.

Confirm the pathway for the individual BIN

Buildings sharing a BBL can have different compliance requirements. DOB identifies Article 320 pathways beginning in 2024, 2026 or 2035 and an Article 321 one-time compliance pathway. City and NYCHA requirements also need separate review. Verify the pathway rather than inferring it from a property-type name.

A public energy grade or benchmarking filing is not an LL97 compliance determination. If the available records conflict, keep the classification unresolved until the relevant evidence is reconciled.

What the BuildingFi lookup can show

Search an address or BBL and confirm the returned BIN. Where a lot has multiple building candidates, choose the matching building before continuing. Review its source year and calculation method.

BuildingFi shows a preliminary screening estimate when its public energy inputs, building identity and calculation pathway support one. Missing or conflicting evidence leaves the estimate unavailable. A modeled result does not establish an assessed amount owed or certify compliance.

For a budget or filing decision, bring the identified record and any discrepancy to DOB or your compliance professional. The lookup does not promise a completed filing, a certified exemption or a financing result.

Questions owners ask

What are the LL97 size thresholds?

LL97 generally covers a building exceeding 25,000 gross square feet; two or more buildings on one tax lot exceeding 50,000 gross square feet together; or two or more condominium buildings under the same board of managers exceeding 50,000 gross square feet together. Exceptions and compliance pathways require building-specific verification.

Is a missing covered-buildings-list entry an exemption?

No. DOB states that the presence or absence of a property on the covered-buildings list does not relieve an owner of legal obligations. Check current records and resolve discrepancies with DOB.

Does being covered mean an annual Article 320 penalty applies?

No. Coverage and compliance pathway are separate questions. Different Article 320 start years, Article 321 requirements and other building-specific circumstances must be verified before an annual-limits calculation is used.

How do I check the right building on a shared lot?

Use the BBL to find the tax lot, then confirm the individual BIN. When several buildings share one lot, select the correct building and reconcile any energy disclosure spanning multiple buildings before using its estimate.
