Do I need a permit for solar panel installation in Dayton?
Yes. In Ohio, solar panel installation generally requires a permit, and Dayton is no exception.
A rooftop or ground-mounted PV system involves both structural and electrical work, so under the Residential Code of Ohio it requires a permit and is not covered by any minor-repair exemption. Utility interconnection is a separate approval from your building or electrical permit; both must be complete before the system is energized. A rooftop solar project in Dayton generally carries both a building scope for the mounting and a separate electrical permit, and the array must meet the Residential Code of Ohio as enforced by the City, so plan for more than one permit and inspection. Electrical contractors must register and post a bond with the City of Dayton before a permit is issued, and trade contractors should hold the correct Ohio Construction Industry Licensing Board (OCILB) license, so confirm registration before signing an installer. Dayton currently takes permit applications in person with three copies of construction documents rather than fully online, and review can take up to 30 calendar days, so build that lead time into the project.
