Start by confirming your property address and zoning restrictions before preparing plans.

Permits & Process

Most residential and commercial solar PV projects require a building permit and an electrical permit, and they are reviewed by the city Building & Safety and the Planning Division when system size or placement affects zoning or roof structure. Typical steps include submitting site and electrical plans, plan check, paying fees, scheduling inspections, and receiving a final inspection and certificate of completion.

  • Permit types: building permit and electrical permit for PV installations.
  • Plan submittal: site plan, roof layout, module and inverter specs, and electrical one-line diagram.
  • Timeline: plan review and approval times vary by project complexity.
  • Fees: fees are charged for plan check and permits; specific amounts are set by the city fee schedule.

Penalties & Enforcement

Enforcement of building and electrical permit requirements is handled by the City of Rancho Cucamonga Building & Safety and Code Enforcement. The city requires permits be obtained before work begins; specific monetary fines and schedules for unpermitted solar work are not specified on the cited municipal permit page.
