NYC DOB Structural Permit and Requirements
A Structural (ST) permit covers regulated building structural work affecting the load-bearing system or related structural elements. Owners considering work on beams, columns, load-bearing walls, floors or structural supports should identify the affected load path and associated building project.
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 Structural Permit?
A Structural (ST) permit covers regulated building structural work affecting the load-bearing system or related structural elements.
DOB’s FAQ notes that Structural must be selected as its own work type to include required technical reports. Certain partial demolition activities are treated within the ST work scope rather than Full Demolition.

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 existing and proposed structural drawings and calculations, along with loads, connections, temporary supports and affected systems.
Structural work affects a building’s load-bearing elements and requires the correct technical scope even when it is part of a larger interior renovation. Review the existing structural plans, proposed framing or load changes, and whether any selective demolition is involved. DOB’s Structural work type is separate from General Construction, Foundation, and Earthwork, although related filings may form part of one job. The responsible design professional should decide whether the proposed scope requires ST rather than assuming an architectural alteration permit covers the structural portion.
Work Type, Agency and Permit Boundaries
Structural is a distinct work type from GC, FO and EA. It can be associated with an Alteration-CO or NB job, and certain GC and ST filings may be combine filed.
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 RDP determines the Structural work type and submits DOB NOW plans. The permit holder must satisfy applicable structural and project prerequisites before work begins.
- 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:
- Existing and proposed structural drawings and calculations.
- Loads, connections, temporary supports and affected systems.
- Building job type, structural work description and related GC filing.
- Technical reports, special inspection scope and adjacent-property details.
DOB Review, Inspections and Closeout
Track required inspections and final technical reports. Separate Structural issuance or renewal conditions can apply when a job is tied to new construction, enlargement or occupancy changes.
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.
Keep the approved structural drawings and required inspection or technical-report records linked to the specific ST filing. During construction, a field condition or substitution involving beams, columns, or supports should be reviewed before changes are made. Temporary bracing or excavation-support measures may also require their own review depending on the work. The owner should track the structural permit’s completion status separately from finishes or other GC work so that closeout does not leave a structural filing unresolved.
Common Problems to Avoid
Load-bearing work classified only as GC
Have the responsible RDP confirm whether ST is needed.
Technical reports missing
Verify required inspections and reports for the Structural work type.
Parent job not coordinated
Link the structural permit to the correct alteration or new building job as applicable.
How SLK Buildings May Assist
SLK Buildings may assist with Structural Permit coordination by reviewing available DOB records, organizing project information and identifying which applicant, licensed contractor or agency contact needs to handle the next action.
The authorized design and trade professionals remain responsible for regulated submissions and work, and DOB controls permit decisions, inspections and completion. Owners can begin by gathering the property address, existing filing numbers and a clear description of the proposed work.

Seeking Professional Guidance on NYC DOB Permits and Certificates
Property owners and project teams may need to confirm which DOB authorization applies, distinguish historical permits from current work types, and organize existing drawings, job numbers and approved records. When permits, certificates or multiple trades are involved, the responsible professionals and DOB must determine the permitted scope and required approvals.
