Local Project Overview
Solar Panel Installation · Montgomery County, Maryland
Permit required
In Maryland, a Solar Panel Installation requires a building and electrical permit.
DPS launched "eSolar" (2023), the first county-level SolarAPP+-integrated automated solar permitting program in Maryland, requiring a building permit (attachment) plus a separate electrical permit; MHIC-licensed contractor required (homeowners cannot self-apply). Statewide, the 2024 Brighter Tomorrow Act and 2026 Utility RELIEF Act (HB1532) now mandate SolarAPP+ adoption across all of Maryland with a residential permit fee cap of $500. Plans are reviewed under the Montgomery County Department of Permitting Services (DPS) code (IRC Maryland Building Pe); apply through Montgomery County Department of Permitting Services before work begins.
