Do I need a permit for addition or structural alteration in Columbus?
Yes. In Ohio, addition or structural alteration generally requires a permit, and Columbus is no exception.
Under the Residential Code of Ohio, enlarging or structurally altering a dwelling requires a permit and is never covered by the minor-repair exemption. An addition can trigger separate zoning, setback, or floodplain review in addition to the building permit; confirm requirements with your local department early. Columbus BZS treats building a room addition or similar structural work as a project that requires a permit and plan review under the Residential Code of Ohio. Additions usually trigger a zoning review for setbacks, height, and lot coverage, and any attached electrical, plumbing, or mechanical work needs its own trade permits. Plans and permits are submitted through the City of Columbus Citizen Access Portal, and larger projects may fall under the electronic plan review submission standard.
