Permit takeaway
Dayton says deck permit applications require three copies of a site plan, drawings, and a permit application, and similar plan submittals are needed for garages and additions.
Zoning and placement
Decks, garages, and additions should be checked for zoning placement, special property conditions, and accessory structure limits before building review.
Building and trade review
Attached garages can require additional fire separation and structural connection information under the Residential Code of Ohio.
