Full Breakdown
00. 921. For a building-mounted system, the panels are generally held to the same dimensional standards that apply to the building itself, but residential roof mounts get a specific height rule: the array can extend no more than three feet above the roof surface at its exterior perimeter, and must step back at least one foot from that perimeter for every additional foot it rises above the roof height. On a gable, gambrel, hip or mansard roof, the system may extend up to three feet above the ridge.
Commercial and industrial roof mounts get more room, a system on a commercial or industrial building within five feet of another commercial or industrial building on an adjoining lot can rise up to fifteen feet above a flat roof along the shared property line. Freestanding, ground-mounted systems are treated as accessory buildings for height, lot coverage and placement purposes; in residential districts they're capped at fifteen feet within ten feet of a parkway or interior property line (excluding alley lines), with additional height allowed as the system sets back further, up to a twenty-five-foot maximum.
Violations & Fines
Installing a solar array without the Chapter 33 building permit, or building one that busts the § 65.921 height and setback standards, is enforced the same as any zoning or building code violation in Saint Paul: the building official can red-tag the installation and require it be brought into compliance or removed, and unpermitted work is subject to the doubled penalty fee under § 33.04(a) if work starts before a permit issues.
