PLACE OF ASSEMBLY
CERTIFICATE OF OPERATION (PACO)
Under the NYC Building Code and Department of Buildings (DOB) regulations, a Place of Assembly (PA) is generally a space where 75 or more people gather indoors or on a roof terrace, or where 200 or more people gather outdoors. Common examples include restaurants, lecture halls, theaters, stadiums, banquet halls, amusement venues, museums, and similar assembly spaces.
Before legally operating a Place of Assembly, the space generally requires a Place of Assembly Certificate of Operation (PACO), a posted occupant capacity sign, and compliance with all applicable DOB and FDNY requirements. The required filing path depends on the building's approved history, the proposed use, the occupant load, and whether the scope of work affects egress, fire protection, accessibility, seating layouts, or other regulated conditions.
ESTABLISHING A NEW PLACE OF ASSEMBLY
Establishing a new Place of Assembly generally requires obtaining a new Certificate of Occupancy through an Alteration Type-1 (ALT-CO) application.
When consulting on projects that involve establishing a new Place of Assembly within an existing building, I typically recommend the following filing strategy.
1. File an Alteration Type-1 (ALT-CO) Application
If the building already has an approved Alteration Type-1 application on file, I generally recommend maintaining that application and filing an amendment to incorporate the proposed Place of Assembly use or occupancy, subject to authorization by the building owner.
Unless amending an existing "no-work" application, I typically recommend filing the Alteration Type-1 as a single OT-Architectural work type, limiting the construction scope to modifications involving means of egress, fire-rated separations, and required demising partitions.
2. File the Place of Assembly Application (No Work)
The Place of Assembly application should generally be filed and approved simultaneously with the associated Alteration Type-1 application.
Although commonly filed as a "No Work" application, the Place of Assembly drawings should accurately reflect the proposed assembly layout, including:
-
Furniture and seating layout; Occupant load calculations; Means of egress plans; Exit signage and emergency lighting; Any permanent or movable installations located within the assembly space
3. File the Separate Construction Alteration
Depending on the project schedule, construction obligations, lease requirements, and overall scope, I often recommend filing the physical build-out separately under its own Alteration application with the appropriate Architectural, MEP, Structural, and related DOB work types.
Doing so may help streamline construction while allowing the Certificate of Occupancy and Place of Assembly approval process to continue independently.
That said, construction affecting the proposed Place of Assembly should not commence until the proposed Place of Assembly use and occupancy have been approved by the Department of Buildings.
ALTERATION OF AN EXISTING PLACE OF ASSEMBLY
Before jumping into a project involving the alteration of an existing restaurant, lecture hall, museum, or other assembly space, I typically begin with the following review sequence:
1. Review Existing Property Records
Confirm the building's existing legal conditions by reviewing available property records, including the Certificate of Occupancy, prior DOB filings, and any active or expired Place of Assembly permits or Certificates of Operation.
2. Determine Whether a Certificate of Occupancy Exists
If there is no active Certificate of Occupancy (CofO) for the building, there may also be no legally established Place of Assembly on record. In those situations, the architect and owner should generally proceed through the standard filing process to obtain a new Certificate of Occupancy while establishing a new Place of Assembly.
3. Existing Assembly Occupancy Without an
Active PA
If the Certificate of Occupancy reflects an existing Assembly use or occupancy, but there is no active Place of Assembly approval on record with either the DOB or FDNY, the filing process may be simplified. Depending on the proposed scope of work, the architect may consider filing an Alteration Type-2 application (no change in use or occupancy) together with the associated Place of Assembly application.
4. Review Pre-BIS Place of Assembly Records
In some cases, a Place of Assembly approval issued prior to the implementation of BIS (pre-1990) may appear under the Pre-BIS PA records within the DOB Property Profile. Regardless of whether a Pre-BIS approval exists, I recommend confirming whether a new Place of Assembly application is required based on the proposed scope of work.
5. Review the Certificate of Occupancy
An active Certificate of Occupancy issued after 1968 should typically indicate whether a Place of Assembly has previously been established and identify the maximum approved occupant load. The Certificate of Occupancy will generally classify the assembly occupancy using an "F" designation (such as F-3 or F-4).
PA CONSIDERATIONS
-
An office or retail floor is not automatically classified as a Place of Assembly simply because the overall occupant load exceeds 75 persons. The determination depends on the actual gathering space, its intended use, occupant load, configuration, and how the Building Code applies to that specific area.
-
Likewise, many assembly-type spaces with occupant loads below 75 persons—such as small restaurants, cafés, coffee shops, meeting rooms, fitness studios, and similar establishments—may remain classified as Group B occupancies, provided they satisfy the applicable Building Code exceptions.
-
Over the years, I have found Place of Assembly applications to be some of the most interesting—and often the most challenging—projects to work on. In my experience, the pre-design strategy is one of the most important phases of the project because there are often several acceptable approaches to establishing a new Place of Assembly or modifying an existing one.
-
Understanding the applicable regulations before design begins allows the architect, owner, and development team to make informed decisions early in the process, often reducing DOB objections, minimizing costly redesigns, and helping avoid unnecessary delays during construction and final inspections.
-
A new restaurant, banquet hall, museum, art gallery, entertainment venue, or similar assembly space generally cannot legally open to the public until the required Place of Assembly Certificate of Operation (PACO) has been issued. Delays in approvals or inspections can prevent a business from opening and generating revenue. For that reason, I recommend establishing the overall filing, inspection, and sign-off strategy as early as possible—ideally before design documents are finalized.
FAQ'S - PLACE OF ASSEMBLY OCCUPANCIES
1. What is considered a Place of Assembly under the NYC Building Code?
A Place of Assembly is generally a space where 75 or more people gather indoors or on a roof terrace, or 200 or more people gather outdoors. Restaurants, bars, event spaces, theaters, museums, fitness studios, banquet halls, and lecture rooms commonly fall into this category. Occupant load, intended use, and the approved Certificate of Occupancy all play a role in determining whether a Place of Assembly filing is required.
2. Does every restaurant require a Place of Assembly filing?
No. Many restaurants operate below the occupant load threshold and therefore do not require a Place of Assembly Certificate of Operation. The first step is determining the approved occupant load and reviewing the existing Certificate of Occupancy before assuming a PA filing is necessary.
3. Can I renovate an existing Place of Assembly without obtaining a new Certificate of Occupancy?
It depends on the scope of work. Cosmetic renovations may not require a new Certificate of Occupancy, while alterations involving occupancy, egress, fire protection, or changes in use often do. Every project should be evaluated individually before determining the appropriate filing strategy.
4. What is the difference between a Place of Assembly application and a Place of Assembly Certificate of Operation?
The Place of Assembly application is submitted through the Department of Buildings as part of the approval process. Once all required approvals and inspections are completed, the FDNY issues the Place of Assembly Certificate of Operation (PACO), allowing the space to legally operate.
5. How do I know if my building previously had a Place of Assembly approval?
The best place to start is by reviewing the property's Certificate of Occupancy, DOB records, BIS Property Profile, and any historical Place of Assembly permits or Certificates of Operation. Older approvals may also appear as Pre-BIS Place of Assembly records.
6. Can an existing Place of Assembly be reopened if the Certificate of Operation has expired?
Possibly. An expired Certificate of Operation does not necessarily mean the legal Assembly occupancy has been lost. The building's Certificate of Occupancy, prior approvals, and current conditions should all be reviewed before determining the most appropriate filing strategy.
7. What typically triggers a new Place of Assembly filing?
A new filing may be required when establishing a new Assembly occupancy, increasing the occupant load, modifying means of egress, changing seating layouts, altering fire protection systems, or changing the approved use or occupancy of the space.
8. Does increasing my occupant load always require a new filing?
In many cases, yes. Increasing the approved occupant load often affects egress capacity, plumbing fixture requirements, exit widths, and fire protection systems. These items should be evaluated before submitting revised drawings to the Department of Buildings.
9. What agencies are involved in Place of Assembly approvals?
Most projects involve both the New York City Department of Buildings (DOB) and the Fire Department of New York (FDNY). Depending on the project, additional agencies may also become involved, including the Department of Health, Landmarks Preservation Commission, or Department of Consumer and Worker Protection.
10. What is the first step before beginning a Place of Assembly project?
Before discussing design solutions, I recommend confirming the property's existing legal conditions. Reviewing the Certificate of Occupancy, prior DOB filings, Place of Assembly history, and current occupant load often answers many questions before drawings are even prepared. Starting with the building's legal history usually results in a more efficient filing strategy and helps avoid unnecessary revisions.
