Summary
Vanderburgh County lets a homeowner install a rooftop, building, or ground-mounted solar array under 10 acres, used at least partly on-site, without obtaining an Improvement Location Permit at all, as long as the system meets the size, location, height, and setback standards in Section 17.13.020.
A. Compliance with the limited standards and requirements specific to On-site consumption systems (having a solar array of less than 10 acres in size) established herein allows installation of such a system without obtaining an Improvement Location Permit as long as the energy generated is at least partially used on-site for the principal use.
Full Breakdown
020(A) of the Vanderburgh County Zoning Code creates a genuine fast track for residential and other on-site-consumption solar: compliance with the limited standards in that section lets a system with a solar array smaller than 10 acres skip the Improvement Location Permit entirely, so long as at least part of the power generated is used on-site for the property's principal use. Qualifying under the exemption still means meeting real numeric limits. 5 acres or larger, where it can grow to 5,000 square feet, or the property also carries an active agricultural use.
Ground-mounted systems are barred from front yard setbacks, from side setbacks on a corner lot's street side, from any easement or right-of-way, from an operational septic field without County Health Department approval, and from a storm-water conveyance system. Height is capped at 15 feet at maximum tilt for ground-mounted arrays, while roof-mounted systems are exempt from the district's general height standard but still can't rise more than 10 inches above a pitched roof, or 5 feet above a flat roof in A, R-1, or R-2. 28, which do require permitting.
Violations & Fines
A solar system that skips its Improvement Location Permit but fails to meet the Section 17.13.020 size, setback, or height standards is a Title 17 zoning violation under Section 17.36.150. The Area Plan Commission can issue a Notice of Ordinance Violation carrying a civil penalty of up to $500 for a first offense, rising to $1,000, $2,500, $5,000, and $7,500 for further violations within 12 months, due to the County Treasurer within 30 days.
