What your NYC co-op is about to bill you for
The board package looks clean. Minutes read routine, the reserve fund has a number in it, nobody mentions an assessment. None of that tells you what the building is about to be billed for by the city, which is a bill the board can see coming before it shows up in the minutes you've been handed.
Every building over 25k square feet reports its energy use to the city every year and gets back a letter grade, A through D, which it has to post by the front door. That threshold takes in about four out of five prewar elevator buildings and almost no prewar walk-up. Every building taller than six stories also files a facade inspection on a cycle that repeats every five years, coming back either a clean pass or one of two outcomes that mean an inspector has already found work to do. Both are public, both are filed before any board votes on anything, and a facade report short of a clean pass is a repair the building is already on the clock for.
Why the city already knows what your board hasn't told you
The energy grade comes from Local Law 84, which requires large buildings to submit their whole building's energy and water use to the EPA's benchmarking tool every year. The city turns the result into a letter grade under Local Law 33 as amended by Local Law 95:
| ENERGY STAR score | Letter grade |
|---|---|
| 85 and up | A |
| 70 to 84 | B |
| 55 to 69 | C |
| Below 55 | D |
That grade is not filed away somewhere. The building has to print the label and hang it in a conspicuous spot near every public entrance each fall, which means a D has been in the lobby, at eye level, through every showing you attended.
The same annual filing carries the building's energy and fuel use into Local Law 97, which caps greenhouse-gas emissions for any building over 25k square feet. The cap has applied since the 2024 calendar year and the city has been assessing penalties on reports filed since 2025: up to $268 per ton of CO2 over the limit, every year the building stays over. A stricter cap takes effect in 2030.
The grade and the cap measure different things: efficiency against comparable buildings in the first case, absolute emissions per square foot in the second. They come out of the same annual submission, though, so a building with a bad grade is the one where the managing agent should already have an answer about Local Law 97. Where that answer is a retrofit nobody has funded, the money comes from a special assessment more often than from the operating budget.
The facade filing works differently but points at the same kind of bill. Local Law 11 requires periodic inspection of a building's exterior walls by an engineer the owner hires, and the report that comes back carries a status: a clean pass, "SWARMP" (safe with a repair and maintenance program, meaning a conditional pass with work required by a deadline), or "unsafe" (protective measures now, repairs immediately). Either of the non-clean outcomes means an engineer has already written down the scaffolding, masonry and structural work an old building needs, and put the building on a clock to finish it. That is not a risk factor. It is a project with a date on it, priced by contractors who know the deadline is not yours to move.
What typical looks like for a building this old
About 11.2k apartment buildings built before 1940 filed for the 2024 reporting year, the most recently completed one as of August 2026. Roughly 2.1k of them never got a usable ENERGY STAR score (too few operating hours reported, missing meter data, an exemption), which leaves about 9.2k with a letter grade. Of those, 54% came back C or D.
For a building that old, a bad grade is the normal outcome rather than a warning sign. Drop the age filter and every benchmarked apartment building in the city, prewar or not, comes in at 52%. Move the cutoff to 1945 or 1950 and it holds at 53%. Nothing here turns on where "prewar" gets drawn.
The facade side is blunter. About 16.4k buildings were due for a report in cycle 9, the round that ran five years and closed in February 2025. Roughly 2.3k never filed one, which is its own kind of answer. Of the 14.1k that did, 52% came back SWARMP or unsafe. For a building tall enough to be in the program at all, entering a cycle with facade work the city requires you to do is the more likely outcome, not the exception.
Neither figure predicts your specific building. Both tell you what typical looks like, which is the one thing a board package can never supply. A prewar co-op with a C grade and a SWARMP filing is an ordinary prewar co-op, not a distressed one. If the maintenance charge next to those two readings looks low, that is the thing to ask about.
What this changes about reading the board package
A capital assessment doesn't usually reach the minutes until the board has decided how to pay for it, which can be years after the obligation itself arrived. The energy grade and the facade status are public before that vote, because they are filings the city requires rather than disclosures the board chooses. Read them first and read the minutes second: the minutes confirm a decision the filings already made likely.
What they won't tell you is size or timing, or whether the reserve fund is already covering it. A board ahead of a bad grade may be mid-retrofit with a loan in place. What they do tell you is which two questions the managing agent should be able to answer without checking: what the plan is for Local Law 97, and where the building stands in the current facade cycle. An agent who has to go look has told you something too.
Look up the building's address to see its energy grade and facade filing status alongside everything else on file for the lot. The energy filing is keyed to the lot and the facade filing to the individual building on it, so a co-op with two connected buildings can show one facade report and not the other. What a BBL is and where it stops covers that split. And which open violations follow the building to its next owner rounds out the same picture: a violation, an emissions penalty and a facade repair all come out of the same reserve fund.
