Overview of Solar Permitting in Fontana

The City of Fontana requires building permits for most photovoltaic (PV) installations and associated electrical work. Review structural plans, electrical single-line diagrams, and equipment specifications as part of the submittal. Roof-mounted and ground-mounted systems may require zoning review for setbacks, height, and screening depending on location and system size.

Penalties & Enforcement

The City enforces compliance through the Building & Safety and Code Enforcement divisions. Where work is performed without required permits the City may require a stop-work, retroactive permit approval, and corrective work to meet code.

  • Escalation: first, repeat, and continuing offence procedures are not specified on the cited municipal pages.
  • Non-monetary sanctions: stop-work orders, required corrective permits, system disconnection or hold, and referral to court or administrative hearing if unresolved.
  • Enforcer and inspection path: Building & Safety Division and Code Enforcement handle inspections and complaints; see Resources for official contacts and online complaint submission.
