During the sign work, DOB inspections are required at various stages of completion, as well as for final completion. Based on the scope of work, the following inspections from different DOB Inspection Units may be required:
Construction Inspection – Final Inspection
Sign Electrical Inspection – As required, an electrical tag shall be attached in the field or shop after an inspection
Contractors and property Owners should make sure to schedule and complete all of the required DOB inspections. Prior to scheduling an inspection, Contractors must:
Confirm that all construction work completed matches the approved drawings
Periodically check that no safety hazards exist on the active construction project
Confirm that work complies with the Building Code, Zoning Resolution and other requirements
Confirm that all Energy Code requirements are met
Schedule and complete all Special and Progress Inspections performed by SIAs
No self-certification is allowed by a Contractor
Submission of Special Inspections can be done online by Special Inspection Agency.
DOB inspections may be required during various project stages. Such inspection requests may be made online, and any objections raised may be resolved online.
If the Applicant of Record, or his/her designated SIA, elected to self-certify the required DOB inspections, an online notice of intent to self-certify must have been submitted at the project start. Such self-certified inspections may be audited; audit results will be provided to applicant and must be resolved prior to final sign-off.
DOB or the applicant-of-record, or his/her designated SIA, 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
An online tool 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.
