Emergency Backup Power Systems Work & Inspections

Required Backup Power System Inspections

Following the completion of the Emergency Backup Power System installation, Department inspections are required. Based on the type of Emergency Backup Power System, the following inspections may be required:

  • Plumbing – plumbing and gas work
  • Fuel oil storage (Boiler Unit)
  • Final electrical inspection
  • Final construction inspection for sign-off

An Inspector verifies that the field conditions match the approved documents for both installation of panels and equipment. An Inspector also confirms that the equipment is installed per the electrical diagram, which includes connection to the main electric service panel. For plumbing work, the Contractor may self-certify in lieu of a DOB inspection

Inspection Requests

The Department’s online portal for scheduling appointments for required DOB inspections must be used. DOB NOW provides robust online accounts, making it easier to submit applications, make payments, schedule appointments, check the status of an application or inspection, pull permits, and make renewals.

Special and Progress Inspections

Emergency Backup Power installations require, per the Building Code, that certain Special and Progress Inspections be performed during and at the end of construction; see the table below. Prior to Approval, the Applicant is required to identify all required Special and Progress Inspections.  Prior to DOB permit issuance, the Owner must engage a registered Special Inspection Agency (SIA) who takes responsibility for the Special and Progress Inspections.  Applicants may perform these inspections if they are also registered as a SIA.
