Contractors have the option to either require a DOB Inspection or submit a self-certification of the completed work, if applicable. Contractors opting to self-certify must submit a Notice of Intent to Self-certify, with the dates of these self-certified inspections to the Department, and follow-up with the submission of results for self-certified inspections.

DOB inspection unit conducts a random audit of all self-certified notices to ensure compliance of inspected work with Code and regulations.

Such self-certified inspections may be audited; audit results will be provided to applicant and must be resolved prior to final sign-off.
  • Depending on the above, the Department or the applicant shall complete the final sign-off inspection to close the project.
  • If the completed project has changes that are not significant or substantive, an As Built submission shall be allowed. The applicant must submit revised As Built drawings prior to project sign-off
