Start by confirming the actual filing scope
Electrical Plan Review, commonly called EPR, is a specific DOB review process. It should not be confused with every electrical permit or with a co-op board's internal alteration review. The project team should establish whether EPR applies to the proposed installation and how it relates to the primary construction application.
DOB describes review triggers including certain large installations and work above 600 volts. The complete applicability assessment should use the current code and rules, rather than a single threshold taken out of context. Read DOB's electrical code overview.
Build a consistent drawing package
A one-line diagram explains the electrical relationship between the service and distribution equipment. Plans and equipment-room layouts show the physical arrangement. Those views should agree about equipment, ratings, connections, and the boundary between existing and proposed work.
DOB's guidance identifies one-line diagrams, plan views, and equipment-room layouts where required. It also addresses equipment ratings, fault-current information, grounding, and coordination documentation. The precise package depends on the project. Read the electrical work guidance document.
Gather the records behind the drawings
- Current primary application information and a clear electrical scope.
- Existing approved electrical drawings and relevant amendments.
- Service and distribution equipment data, including retained equipment.
- Relevant calculations and protective-device information.
- Prior objections, inspection comments, and records affecting the new work.
- Contacts for the owner, engineering team, filing team, and licensed electrician.
Use current intake instructions
Submission procedures can change. DOB publishes current EPR instructions and service notices, so the filing team should check the live agency page when preparing a submission. Copying an old project's intake email or checklist may omit a newer requirement.
The former Electrical Advisory Board was eliminated in 2019; current projects use the applicable EPR process. Older project records may still refer to EAB. Treat those records as project history and check how DOB's current instructions address the open filing. Current DOB EPR instructions.
Plan for revisions and construction changes
Technical objections should be answered with a coordinated response and the appropriate revised documents. If equipment or installation conditions change during construction, the team should assess the effect on calculations, drawings, and previously reviewed information.
Keep the engineer informed about substitutions early. Engineering support can help evaluate the change, while the filing team and licensed electrician coordinate their respective requirements. Our DOB Electrical Plan Review service explains the types of support that can be included.
