Full Breakdown
The county's building permit code requires a permit for any structure or electrical alteration, including home solar arrays. The Building and Zoning Department's fee schedule sets a specific residential solar rate of $25 per kW with a $200 minimum: separate from the county's commercial solar siting ordinance, which explicitly does not cover a homeowner's personal system used to self-supply their own property. Veterans get a 25% discount and hardship waivers exist for owner-occupied homes under $75,000 in value.
Violations & Fines
Starting construction without an approved permit application triggers a 150% penalty on the normal fee, and violating the permit code is a petty offense enforceable by the state's attorney in circuit court or before the county's Ordinance Violation Hearing Department.
