How the Oakland solar permit works

Last verified: November 11, 2026 · Written and checked by the DuloCore research team

An Oakland solar permit for a typical rooftop system on a house can be issued the same day through SolarAPP+, an automated plan check the City of Oakland accepts for most residential roof-mounted systems (City of Oakland). Your licensed installer normally handles the steps below; knowing them helps you spot delays. Incentive timing is on the home page.

Why automated permits exist

State law SB 379 requires cities with 50,000 or more residents, Oakland among them, to offer an online, automated permit for residential solar of up to 38.4 kW AC, including paired batteries, by September 30, 2023 (California Energy Commission). Oakland uses SolarAPP+, built by the National Renewable Energy Laboratory.

Route 1: SolarAPP+ (same day)

Oakland lists these conditions: the system goes on the rooftop of a permitted main dwelling, no ballasted racking, no building-integrated panels, and the work is done by a California licensed contractor. Battery backup and related electrical work are allowed (City of Oakland).

  1. The contractor registers at SolarAPP+, enters the project and receives an approval number and documents. SolarAPP+ may charge a processing fee.
  2. The contractor applies through the SolarAPP+ form in Oakland's Online Permit Center, attaches the approval, the spec sheet and a Contractors Declaration form, pays online and prints the permit.

Route 2: standard solar permit

Ground-mounted, ballasted, elevated and commercial systems use the regular solar permit in the Online Permit Center. Expect to provide a site plan showing the street and driveway, a roof plan with fire access paths, framing details, mounting information and, for ballasted, ground or elevated systems, structural calculations. Those systems may also need a separate building permit and a construction recycling plan. A main panel replacement, subpanel or battery can go on the solar application (City of Oakland).

Batteries and the Fire Prevention Bureau

Oakland requires Fire Prevention Bureau approval when a single battery exceeds 20 kWh, when the total exceeds 40 kWh in a utility closet, shed or basement, or when 80 kWh or more is installed outside. The rules are in the city's energy storage code bulletin. Most single home batteries are under these limits, but two or more stacked units can cross them.

Fees

Oakland's solar page does not publish a fee amount, and we did not find a current solar fee figure we could verify. Fees are paid online when the permit is issued; see the city's permit fees page or ask the installer to show the fee on your contract.

Inspection, then PG&E

After installation, the contractor schedules the city inspection with the permit number (it starts with SE) through Oakland's inspection scheduling app. Keep the printed permit and documents on site. Questions go to Planning and Building at (510) 238-3891, 250 Frank H. Ogawa Plaza, 2nd Floor (City of Oakland).

Once the city signs off, the installer submits the interconnection application to PG&E. That application must include your initialed and signed California Solar Consumer Protection Guide (CPUC), and your export credit value is set when PG&E grants permission to operate (PG&E). If you are racing the January 1, 2027 property tax deadline on the tax credit page, ask your installer for a date for each step. Who may pull the permit is covered in choosing an installer.
