Permits in Columbus
The City of Columbus Building and Zoning Services handles permits, plan review and inspections (Columbus BZS). Plan review is a normal part of most permit applications (Columbus BZS FAQ). Whether a radon system needs a permit depends on the work, such as a new electrical circuit. We confirm with the office before we start.
