Permits & your utility in Mountain House

In Mountain House, electric service is Modesto Irrigation District (MID), and building permits are issued by San Joaquin County. We pull the permit on every generator installation, coordinate the service and meter to MID's MID Electric Service Guides — Residential Service Guide (of 8 guides), and pass inspection, so it's safe, legal, and protects your home's value.

Mountain House note: PG&E provides only GAS here; electric = MID since 2001. Not obvious for a San Joaquin new-growth area.
