Full Breakdown

Solar photovoltaic installations on Ohio buildings must comply with the Ohio Residential Code (RCO) and Ohio Building Code (OBC) adopted statewide under ORC 3781.10, which incorporate the National Electrical Code Article 690. Local building departments issue permits and conduct inspections, but the technical standards are uniform. The Public Utilities Commission of Ohio (PUCO) sets statewide net metering and interconnection rules under ORC 4928.67 for distribution utilities. ORC 4906 governs utility-scale projects over 50 megawatts through the Ohio Power Siting Board, which preempts local zoning for those projects. Smaller residential systems remain subject to local zoning.

Violations & Penalties

Installing solar without required permits can result in stop-work orders, removal mandates, denial of utility interconnection, and ineligibility for net metering or incentive programs.
