If you are preparing to sell a Manhattan co-op or condo, a buyer may see your building's energy grade before the apartment. For buildings covered by Local Law 33, the city says the 2026 Building Energy Efficiency Rating label must be posted near each public entrance by October 31. The useful seller task is to confirm the actual label, understand what it measures, and ask management about any related building plans before you describe it in a listing.
Know what the grade does and does not say
The NYC Department of Buildings explains that the annual letter grade comes from a building's energy efficiency score, based on benchmarking. The score uses EPA ENERGY STAR Portfolio Manager to compare the building with similar buildings in similar climates. Under the city's scale, A means 85 or higher, B is 70 through 84, C is 55 through 69, and D is below 55. An F means required benchmarking information was not submitted on time; N applies to certain exempt or ineligible buildings.
This is a building-level measure. It is not a forecast of a particular apartment's utility bill, a guarantee about comfort, or a complete account of future capital work. A missing label also does not by itself tell you which grade the building received. Ask the managing agent for the current label and its explanation.
Check the right record before marketing
Ask management for a copy of the 2026 label, the reporting period behind it, and any correction or pending question about the filing. The DOB's 2026 covered-buildings guidance points owners to the city's list using a property's borough, block, and lot number. Confirm that the record corresponds to your building, especially where a tax lot contains more than one building.
The city's February 2026 service notice sets October 31 as the latest date to post the 2026 label. If you are launching a listing before then, use the most current verified information available and date it. If management is still resolving a question, say so rather than substituting last year's grade.
Separate the label from the building's financial plan
Buyers may ask whether a lower grade signals a project or an assessment. Ask the board or managing agent for the approved capital plan, current budget, assessment notices, and any documented schedule. Do not turn a proposed project into a promised completion date or a projected savings claim.
Local Law 97 is a separate building emissions law. Its applicability and compliance path must be checked on their own terms; the energy letter alone does not establish a building's Local Law 97 status. The DOB's Local Law 97 guidance explains the covered-building records and different compliance paths. Have the building's professionals and your attorney review any building-specific answer before sharing it as a fact.
Give buyers a clear, dated answer
Prepare a short file for your agent and attorney with the label, management's written explanation, and any approved work or cost notices. Keep the year attached to every score. In the listing, describe a verified grade accurately, without implying that it measures the apartment's own energy use or predicts future carrying costs. Update the file if the board changes its plan while the apartment is on the market.
Frequently asked questions
Does the building’s energy grade predict my apartment’s utility bills?
No. The label reports a building-level efficiency score; it does not forecast an individual apartment’s usage or monthly costs. Ask management for the current label, and describe the building’s grade without presenting it as a unit-specific estimate.
Does a low energy grade mean the building has a Local Law 97 penalty?
Not necessarily. Local Law 97 has separate emissions limits and compliance requirements, so the letter grade alone cannot establish whether a building owes a penalty. Ask the board or managing agent for building-specific compliance information and have the appropriate professionals review it.
What if the 2026 label is not posted when I list?
Ask management for the current label and its posting status before making a claim in marketing materials. The city says covered buildings must display the 2026 label by October 31, 2026. Until you have verified information, do not substitute an older grade or guess what the current one will be.
