Key fact: Tustin is a centrally located OC city with a mix of older established neighborhoods and newer master-planned communities including Tustin Legacy — diverse solar market.
Tustin is a mid-sized Orange County city strategically located between Irvine, Orange, and Santa Ana. The city has a dual character: older established residential neighborhoods in West Tustin with 1960s–1980s housing, and the newer Tustin Legacy development (built on the former MCAS Tustin site) with contemporary master-planned communities. This mix creates demand across all permit types — older neighborhoods for panel replacements and solar retrofits, newer areas for first-time solar and EV charger installations.
Tustin Building Division processes permits with review times of 10–16 days for solar — competitive within central Orange County. The department has online submittal capabilities and is generally accessible.
