The number that isn’t a rule
In September 2010, the Department of Buildings sent Pompeii Lounge, at 3133 East Tremont Avenue in the Bronx, a letter of intent to revoke its assembly permit. The permit then allowed occupancy of approximately 180 people. The letter, as reported by the Bronx Times, limited the number of people who could be inside to 75 if the operator’s objections were not addressed.
That 75 is the number in this headline. It is not a code threshold. It is not the line at which a room becomes a place of assembly in New York City. It is what one enforcement action produced in one room, on one date, after DOB audited the floor plan against what had actually been built. The distinction matters because the city’s nightlife conversation keeps reaching for a magic number — 75, 200, 250 — when the document that governs any given room states its own occupant load, and enforcement compares the assembled crowd to that figure.
Three documented cases show the same mechanism at different scales: a Bronx lounge whose permit was threatened with revocation, a Greenpoint bar cited for operating an unpermitted place of assembly, and an open-air Brooklyn venue whose legality was renewed annually under a temporary certificate. None of them turns on cultural value. All of them turn on paperwork.
Pompeii Lounge: the audit, the letter, the appeal
The Bronx Times reported in October 2010 that Pompeii Lounge had appealed a notice of intent to revoke its assembly permit for having built contrary to the plans on file with DOB when it opened about a year earlier. On July 19 of that year, the club was found operating contrary to its occupancy permit, with an illegal cabaret. DOB then audited the floor plan of the lounge and bar and issued the letter on September 9.
The sequence is the point. A complaint or inspection leads to a comparison between the approved plans and the built room. The mismatch produces a letter of intent to revoke. The operator can appeal and meet with DOB to address objections. A DOB spokeswoman told the Bronx Times that the club had made an appointment to address the issues and that its permit had not been revoked while objections were being resolved.
So the 75-person cap was a negotiating position backed by the threat of revocation, not a permanent statutory ceiling. It was also far below the roughly 180 the permit allowed. For an artist-run space, the lesson is not “stay under 75.” It is that the authorized occupant load lives in a document, and that document can be narrowed by an enforcement action faster than a room can reprint its tickets.
Saint Vitus: 250 people, no certificate
On a Friday night in February 2024, DOB inspectors closed Saint Vitus Bar on Manhattan Avenue in Greenpoint in the middle of a performance. ABC7 reported that inspectors found approximately 250 people assembled in what the department called an illegal eating and drinking establishment, and issued a violation to the property owner for “operating the unpermitted place of assembly, contrary to the legal occupancy of the building.”
The same report states that DOB said the venue never applied for a certificate of occupancy when it opened in 2011, and that this was the second such violation, the first having been issued in July 2023. City Councilmember Keith Powers told the station the venue needed a temporary certificate of occupancy to operate and come into compliance.
Read the violation language closely. It does not say the room was too loud, or that the crowd was disorderly, or that the show was bad for the neighborhood. It says the place of assembly was unpermitted and the assembly was contrary to the legal occupancy of the building. The number 250 appears in the reporting as what inspectors counted. The legal question is what the building’s certificate authorized — and according to DOB, as reported, there was no certificate application to compare it against.
This is the hardest version of the mechanism for a scene that values the room over the file. A venue can run for more than a decade, host hundreds of shows, and still be, in the department’s terms, an unpermitted place of assembly. The enforcement record does not credit the decade.
Brooklyn Mirage: legality renewed every year
The large-room contrast is the Brooklyn Mirage. Billboard reported that the 32,000-square-foot open-air venue, which opened in 2017, functioned under a Temporary Place of Assembly Certificate of Occupancy that had to be renewed annually because it operates only in warmer months. When a 2025 redesign included a prefabricated wooden structure standing 65 feet high and nearly 200 feet long, the scale complicated the city’s permitting process, and DOB declined to issue the necessary permits. The venue did not reopen on schedule. Avant Gardner filed for Chapter 11 bankruptcy in August, with Billboard reporting about $194 million owed to creditors.
A temporary PA certificate changes the administrative math. For a room like the Mirage, legality is not settled once at buildout and then forgotten. It is a recurring filing, tied to a season, renewed or refused each year. A redesign that changes the structure’s height and footprint reopens the permitting question rather than inheriting the old answer. The cost of that recurrence — architectural work, filing time, inspection scheduling — is a fixed operating expense that a smaller artist-run space may never have budgeted because it never had a certificate to renew in the first place.
The Mirage’s scale is not the lesson. The lesson is that a temporary certificate makes compliance a calendar item. A room that plans its season without planning its renewal is planning to be closed in the middle of one.
What the certificate actually decides
New York City’s Construction Codes consist of the General Administrative Provisions, Building Code, Fuel Gas Code, Mechanical Code, and Plumbing Code, according to the DOB codes page. The certificate of occupancy or place of assembly certificate is the document that states what a building may legally be used for and how many occupants that use authorizes. Enforcement, as the three cases show, compares the assembled crowd and the actual use to that document.
For an artist-run space, this reframes the capacity question. The useful question is not “how many people fit in the room.” It is “what occupant load does the certificate authorize, and does the crowd on the night of the show match it.” A hypothetical, clearly labeled as such: a 200-capacity room whose certificate authorizes 120 is legally a 120-person room on the night an inspector counts, regardless of what the ticket page says. The gap between the two numbers is the exposure.
That gap is also a budget line. A room that has never obtained a certificate is not saving the filing cost; it is carrying the risk of a shutdown, a violation against the property owner, and the legal work to come into compliance — the sequence Saint Vitus entered in February 2024. A room that holds a temporary certificate is carrying an annual renewal cost. Neither is free. The question is which cost the room has chosen to see.
What the record does not settle
None of the retrieved reporting establishes the code text that defines when a place of assembly certificate is required, how occupant load is calculated, what the filing fees are, or how long DOB review takes. The DOB place-of-assembly and certificate-of-occupancy pages did not load for this piece, and the application PDF was unavailable. The 75-person figure should not be repeated as a general rule; it is the Pompeii enforcement outcome. The 250 at Saint Vitus is an inspector’s count, not a legal capacity. The Mirage’s annual renewal is specific to a temporary certificate for a seasonal open-air venue.
What the record does establish is the mechanism: DOB audits the built room against the filed plans, issues violations or letters of intent tied to legal occupancy, and allows operators to appeal and address objections. The document sets the ceiling. The crowd is measured against it. Cultural value does not appear in the violation language.
For anyone running a room in Brooklyn, the practical move is to pull the certificate of occupancy for the address before the next show is announced, read the authorized use and occupant load, and compare them to what the night actually is. If the answer is uncomfortable, the time to find out is before an inspector counts.
FAQ
Is 75 people a legal threshold for place of assembly occupancy in New York City?
No. The 75-person figure comes from a September 2010 DOB letter of intent to revoke Pompeii Lounge’s assembly permit, which limited occupancy to 75 if concerns were not addressed. It was an enforcement outcome in one case, not a code-defined threshold. The retrieved sources do not establish a general occupancy number that triggers place of assembly review.
What is the difference between a certificate of occupancy and a place of assembly certificate?
A certificate of occupancy states the legal use and occupant load of a building. A place of assembly certificate applies to spaces used for assembly of people, such as performance venues. The retrieved sources describe both being at issue in enforcement actions but do not provide the code text defining when each is required.
Can a venue operate under a temporary place of assembly certificate?
Yes, in the case documented by Billboard: the Brooklyn Mirage, an open-air seasonal venue, functioned under a Temporary Place of Assembly Certificate of Occupancy that had to be renewed annually. The temporary status made compliance a recurring filing rather than a one-time approval.
What happens if DOB finds a crowd larger than the legal occupancy?
In the Saint Vitus case, DOB inspectors found approximately 250 people assembled in what the department called an illegal eating and drinking establishment and issued a violation to the property owner for operating an unpermitted place of assembly contrary to the legal occupancy of the building. The venue was closed during a performance. The reporting does not describe the full penalty schedule.
Where can I check the legal occupancy of a Brooklyn address?
DOB maintains public records through its codes and certificate-of-occupancy pages, though those pages did not load for this piece. The retrieved sources do not provide a step-by-step procedure for pulling a specific address’s certificate. A licensed professional can confirm which laws apply to a given building, as DOB’s own codes page notes.
