Rockville's 1980 median housing-unit year and dense Montgomery County setting mean many installs blend older panel capacity checks with newer infill or townhouse parking constraints. The local quote should verify Pepco service, private parking, and whether the work goes through Rockville's online electrical-permit inspection process.

Permit required: Yes
Rockville's permits and inspections page directs residents to the city's online permitting system for electrical permits and inspections, while Montgomery County DEP's EV charging guidance tells Rockville-area homeowners to apply for a residential electrical permit to install a Level 2 charger for a garage or driveway.
