Full Breakdown
Under Chattanooga's accessory-structure standards, reviewed as part of zoning/building permitting, solar panels may be building-mounted or freestanding. Roof-mounted panels on pitched roofs can rise up to 18 inches above the roof; on flat roofs under 40 feet tall the cap is six feet above the roof surface. Wall-mounted panels may project up to four feet from the facade but can't encroach more than three feet into a required setback. Freestanding systems are rear-yard only, set back ten feet from every lot line, and capped at 20 feet in height. All panels must avoid directing glare onto neighboring properties or roadways, and installations in historic districts may need a certificate of appropriateness.
Violations & Fines
Land Development Office permit review enforces the height, setback, and glare standards; historic-district installations lacking a certificate of appropriateness can be ordered modified or removed.
