Alameda County offers 3-business-day solar permitting under AB 2188 and SB 379. Systems must comply with Title 24 and the 2022 Solar Mandate for new homes.
Solar permitting in Alameda County and its cities follows California AB 2188 (2014) and SB 379 (2022) requiring expedited online permitting for residential rooftop PV systems up to 38.4 kW DC. Most jurisdictions including Oakland, Fremont, Hayward, and unincorporated Alameda County use the SolarAPP+ automated plan review tool for same-day or 3-business-day approvals. Permit fees are capped at 450 dollars for residential systems and 1,000 dollars for commercial per SB 379. California Title 24 Building Energy Efficiency Standards 2022 version require solar on all new single-family homes and most new multifamily and commercial buildings (Solar Mandate). Net Energy Metering 3.0 (NEM 3.0) applies to systems interconnected after April 15, 2023, reducing export compensation by roughly 75 percent compared to NEM 2.0 but maintaining grandfathering for existing systems. PG&E handles interconnection.
