Summary
Dayton's Zoning Code sets citywide dimensional limits on building-mounted solar panels, how far they can project past the roof or building side, and requires a Certificate of Appropriateness before installing panels on property inside a historic overlay district.
Building solar panels proposed in a historic district shall require a Certificate of Appropriateness. Building solar panels may be attached to any part of a roof in accordance with the requirements of this Section. Building solar panels shall not be attached to the side of a building that faces a public street, alleys excluded. The term "side" does not mean "roof."

Full Breakdown
Zoning Code § 150.565.67 governs building solar panels in every Dayton district. Roof-mounted panels may extend up to one foot past the roof plane generally, never more than three feet, and cannot attach to a building side facing a public street (alleys excluded). Side-mounted panels are capped at five feet of projection. Property inside a historic overlay district needs a Certificate of Appropriateness before installation, reviewed as a minor modification. The Zoning Administrator enforces the chapter and, under § 150.130.7, can assess civil penalties up to $1,000 per day of ongoing violation after notice.
Violations & Fines
Installing panels that exceed the roof/side extension limits, or skipping a required historic-district Certificate of Appropriateness, is a Zoning Code violation; the Zoning Administrator can assess civil penalties up to $1,000 per day under § 150.130.7.
