Santa Clarita, CA Solar Energy: Panel Permits (2026)

060, a small residential rooftop solar system must be 10 kW AC or less, roof-mounted on a single or duplex dwelling or accessory structure, utility-interactive without battery storage, and wired within specific limits: no more than four PV module strings per MPPT input where the inverter includes source-circuit fusing, no more than one non-inverter DC combiner per inverter, and interconnection to a single-phase 120/220-volt panel rated 225 amps or less on the load side. The applicant must also verify through standard engineering evaluation that the roof structure can carry the added wind, seismic, dead, and live loads, and show fire-safety compliance including clear roof access pathways meeting Los Angeles County Fire Department requirements and a Class A or Class B roof rating.

040 requires every system to meet the standards of the City's Electrical, Building, and Fire Codes and the Institute of Electrical and Electronics Engineers, and caps panel height at the Municipal Code's maximum legal building height. 050, submittable on paper or electronically. 070(D) bars the City from conditioning approval on HOA sign-off. 080 caps an eligible system to one inspection, scheduled within two business days with a four-hour window on request, though a failed inspection or two prior failures can add a reinspection fee.
