Merced County, CA Solar Energy: Panel Permits (2026)

030 sets the permit path for a 'small residential rooftop solar energy system,' defined as a system no larger than 10 kilowatts alternating current (or 30 kilowatts thermal) installed on a single- or duplex-family home, meeting state fire, structural, and electrical codes, and not exceeding the maximum legal building height. Before filing, subsection E requires the applicant to verify, using standard engineering evaluation techniques, that the roof's support structure can carry the system's added wind, seismic, dead, and live loads down to the foundation, and, at the applicant's own cost, to verify with standard electrical inspection techniques that the home's existing wiring, grounding, bonding, and panel or subpanel sizing can carry the new photovoltaic load.

Subsection D lets the applicant submit the permit application and supporting documents to the Merced County building and safety division in person, by mail, or electronically, together with the required permit-processing and inspection fees; the county publishes its compliance checklist on its own website. Under subsection G, an application meeting every item on that checklist is deemed complete as soon as the building official confirms it; an incomplete filing draws a written correction notice listing every deficiency. Subsection H then requires the building official to administratively approve a complete application and issue the permit, though the applicant must separately obtain the utility's approval before connecting the system to the grid.
