City of Columbus registered special inspectors perform and report on inspections that are specific to certain aspects of building construction and outside the expertise of inspectors employed with this department.

A special inspection is an inspection of construction that requires the expertise of an approved special inspector in order to ensure compliance with the Ohio Building Code and the approved documents.  Generally speaking, it is an inspection requiring extensive knowledge, equipment or testing above what a certified building inspector or department can reasonably provide.  A list of special inspections can be found in Chapter 17 of the Ohio Building Code and are listed on Statement of Special Inspections form that accompanies some plan approval letters issued by the Department of Building and Zoning Services.

Special inspector applications are reviewed by the Columbus Building Commission. The commission meets once per month. Applicants must submit their application and payment no later than one (1) week prior to the next scheduled board meeting. Please see the Boards and Commissions page on this site for more information.

Applicants are not required to be present at the board meeting. However, special inspectors may appear before the Columbus Building Commission for due process complaints (filed against or by the contractor).
