NYC DOB Temporary Place of Assembly Certificate of Operation (TPACO)
A Temporary Place of Assembly Certificate of Operation (TPACO) is a DOB-issued certificate for qualifying short-term assembly events, not a construction work permit. A temporary event may require TPACO when 75 or more people gather indoors or 200 or more outdoors, subject to the current applicable rules and event arrangement.
Start with the DOB Permit Types and Certificates of Operation directory for the complete work-type list, or use the Department of Buildings Table of Content for wider NYC DOB subjects. Check the work scope and responsible applicant before treating an application as an issued authorization.
What Is a Temporary Place of Assembly Certificate of Operation?
A Temporary Place of Assembly Certificate of Operation (TPACO) is a DOB-issued certificate for qualifying short-term assembly events, rather than a construction permit.
NYC Business guidance directs TPACO filings through DOB NOW: Build and explains advance application expectations. Organizers should confirm current instructions well before the event.

When Does This DOB Authorization Apply?
Deciding whether this authorization applies requires a property-specific review of the proposed work, the existing conditions and the current agency records. In particular, compare event dates, location, purpose and responsible organizer, along with temporary occupancy and crowd arrangements with exit details.
A TPACO application concerns a qualifying temporary assembly use, so the event dates and physical layout matter as much as the intended audience size. Review the location, entrances, exits, circulation paths, and seating or standing arrangement. Temporary stages, tents, platforms, or bleachers may introduce additional building-work filings and supporting documents. A temporary certificate is not interchangeable with the PACO process for a permanent assembly space, and organizers should not assume existing venue approvals automatically cover a new event configuration.
Work Type, Agency and Permit Boundaries
TPACO is distinct from the permanent PACO process. Temporary stages, bleachers, tents or other structures may need separate DOB construction permits and technical reports; FDNY can have separate fire-safety authority.
DOB NOW: Build is the standard current filing platform for this subject. The authorized filer and contractor roles depend on the regulated work, and separate agency permissions may still be necessary.
Steps to Request or Review the DOB Authorization
Use the following sequence to avoid applying against the wrong property record or work scope:
- Confirm the building address, Building Identification Number (BIN), and existing job or equipment record. Check whether the project is new work or an older open job.
- Define the exact work or certificate need with the authorized professional. Compare the project details with the DOB work type and any separate trade or agency approvals.
- The responsible event applicant prepares the TPA/TPACO filing in DOB NOW and provides supporting documents. Separate construction work-permit filings are needed for regulated temporary structures as applicable.
- Review the submitted filing and DOB status. Address objections, missing documents, required attestations and pre-permit conditions through the authorized applicant.
- Confirm the issued permit or certificate and the approved work limitations before acting. Save the final record and track inspection or completion duties.
Documents and Information to Prepare
The responsible applicant should assemble project-specific information before starting the filing or records review:
- Event dates, location, purpose and responsible organizer.
- Temporary occupancy and crowd arrangements with exit details.
- Plans for tents, stages, platforms or bleachers when applicable.
- Relevant property approvals and required fire-safety information.
DOB Review, Inspections and Closeout
Confirm the certificate, permitted event conditions and any applicable FDNY or public-space requirements before opening the event. TPACO does not convert the event into a permanently authorized assembly use.
An application marked approved, a permit issued and a project signed off are different milestones. Review the applicable status in DOB NOW or BIS, and retain supporting inspection and closeout documentation for the property record.
Start the records review early enough to identify the DOB NOW filing, any required plans, and independent agency authorizations. Keep the TPACO application and issued certificate connected to the specific event dates and approved setup. FDNY may require separate fire-safety permissions or conditions. If the organizer changes the occupant arrangement, location, or temporary structures, the responsible applicant should check whether the approved documents remain valid. At the end of the event, preserve the certificate and related approvals as distinct records rather than treating them as permanent permissions for future events.
Common Problems to Avoid
Permanent and temporary certificates confused
Choose PACO or TPACO based on the actual use and duration.
Temporary structures omitted
Check separate permits for stages, tents, bleachers and related work.
Application left too late
Review current DOB processing guidance before booking the event date.
