Summary
Before filing a Union City rooftop solar permit application, homeowners must verify the roof structure can carry the system's loads and confirm the home's electrical panel and wiring can handle the added photovoltaic load.
Prior to submitting an application, the applicant shall:
A. Verify to the applicant's reasonable satisfaction through the use of standard engineering evaluation techniques that the support structure for the small residential rooftop solar energy system is stable and adequate to transfer all wind, seismic, and dead and live loads associated with the system to the building foundation; and
B. At the applicant's cost, verify to the applicant's reasonable satisfaction using standard electrical inspection techniques that the existing electrical system including existing line, load, ground and bonding wiring as well as main panel and subpanel sizes are adequately sized, based on the existing electrical system's current use, to carry all new photovoltaic electrical loads. (Ord. 808-15 § 4, 2015)

Full Breakdown
Union City Municipal Code § 15.78.060 requires applicants for a small residential rooftop solar energy system permit to complete two verifications before submitting: an engineering evaluation confirming the roof support structure can transfer all wind, seismic, dead, and live loads to the building foundation, and, at the applicant's own cost, an electrical inspection confirming existing line, load, ground, bonding wiring, and panel/subpanel capacity can carry the new photovoltaic load. Applications then go to the Building Division in person, by mail, or electronically per § 15.78.050, with permit and inspection fees set under § 15.78.080.
Violations & Fines
The chapter sets no separate solar-specific penalty; installing panels without the verified, permitted application is enforced as unpermitted work under Union City's general Building Code infraction schedule.
