Santa Monica’s neighborhoods each carry a distinct housing era. Sunset Park, south of Pico Boulevard, is largely made up of small one-story homes built in the 1920s through the 1940s for workers at the old Douglas Aircraft Factory, and many still have original subpanels that can’t keep up with modern garage workshops, added outlets, or EV chargers. North of Wilshire and south of Montana Avenue, a grid of numbered streets holds a mix of Craftsman bungalows and well-preserved Victorian duplexes, while the area north of Montana Avenue has larger homes on bigger lots with more varied electrical setups. Electric service throughout Santa Monica comes from Southern California Edison (SCE), not a city-owned utility. Building and electrical permits are issued by the City of Santa Monica through its Permit Services Center, which handles plan check and permitting for residential electrical work. Coastal humidity and marine air add some corrosion risk to garage and exterior outlets closer to the beach, which is a recurring reason for outlet and panel service calls in this area.
