Palo Alto strongly supports residential solar with online SolarAPP+ permitting, Title 24 solar mandate compliance for new homes, and CPAU net energy metering programs.
Palo Alto is one of the most solar-friendly cities in California, participating in SolarAPP+ for same-day automated solar permitting of residential rooftop PV systems. The California Title 24 Solar Mandate requires solar on all new residential construction and significant additions, implemented through building permits. AB 1236 (Government Code 65850.5) requires cities to adopt streamlined solar permit processes, which Palo Alto exceeds with online automated review. Palo Alto Municipal Utilities (CPAU) offers net energy metering (NEM) under its own tariff (not CPUC NEM 3.0 because Palo Alto is a municipal utility), providing more favorable terms than IOU territories. Battery storage systems paired with solar require additional electrical permits and fire-setback review under CRC Chapter 7A. Historic district and Eichler neighborhood installations may require Historic Resources Board review for visual impact. Commercial solar over certain sizes triggers structural and electrical engineering review.
