Do I need a permit for addition or structural alteration in Blue Ash?
Yes. In Ohio, addition or structural alteration generally requires a permit, and Blue Ash 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. Blue Ash requires a building permit for new room additions, new porches and decks, and any alteration of structural supports such as floor joists, wall studs, rafters, and beams. The building permit application automatically triggers a zoning code review, so setbacks and lot coverage are checked as part of the process. Allow roughly 5 to 7 business days for residential plan review and confirm submittal requirements with the Blue Ash Building Department at 513-745-8522.
