Ontario issues same-day online solar permits under AB 2188 and the statewide SolarAPP+ automated plan check, and new single-family homes must include solar under the 2019 Title 24 Solar Mandate.
Ontario Building and Safety processes residential rooftop solar photovoltaic permits through an expedited online system consistent with California AB 2188 (Solar Rights Act) and SB 379, and has adopted SolarAPP+ for automated plan review. Standard residential systems up to 15 kW on existing single-family homes receive an instant permit once the SolarAPP+ checklist passes. Plan check by staff is limited to structural, fire-setback, and electrical code compliance. The 2019 California Title 24 Part 6 Solar Mandate (updated in 2022) requires that new single-family homes and low-rise multifamily built in Ontario include a solar PV system sized for annual electric load. Fire-code setbacks under California Fire Code 1205 require clear pathways on pitched roofs (typically 3 feet to the ridge) unless covered by California Residential Code alternate paths. Interconnection is handled by Southern California Edison via Rule 21 net energy metering. HOA-imposed bans violate Civil Code 714.
