Utility and rates
Azusa runs its own municipal utility, Azusa Light & Water, not SCE. Its interconnection rules, net metering credits, and rate schedules differ from SCE's, and the system has to be designed around them. We review your Azusa Light & Water bill before proposing a system size.
For systems of 10 kW DC or less, Azusa Light & Water credits your net generation kilowatt-hour for kilowatt-hour and rolls unused credits forward year to year, with any annual surplus paid out under its Schedule NGP (8.85 cents per kWh for July 2026 through June 2027). That is a better deal than SCE net billing, which changes how we size the system. One rule to know: a battery on Azusa Light & Water must be set up so it never exports to the grid, so it runs for backup and self-consumption only. Solar customers are also not eligible for the utility's residential EV rate.
Permits
Building and electrical permits in Azusa are issued by the City of Azusa Building Division at 213 E. Foothill Blvd, but only after Azusa Light & Water signs off. VertX prepares the plan set, files the application, and schedules the final inspection; you sign, we handle the rest.
Azusa has a two-step process most cities do not. First, the signed interconnection agreement and the California Solar Consumer Protection Guide go to Azusa Light & Water customer service, which issues a release form. The Building Division requires that form before it will accept the expedited solar submittal (10 kW or less) by email. After the building final, the utility does its own inspection and installs the net meter; it does not issue a permission-to-operate letter.
Fire and outages
Azusa sits at the mouth of San Gabriel Canyon, and the northern foothills, including Mountain Cove, Rainbow Ranch, and the homes north of Sierra Madre Avenue, are mapped as a Very High Fire Hazard Severity Zone. The Colby Fire (January 2014) burned into the city and evacuated hundreds of homes, the San Gabriel Complex (June 2016) forced Mountain Cove and Rainbow Ranch to evacuate, and the Bobcat (2020) and Bridge (2024) fires both started in the canyon above town. Azusa Light & Water is not SCE, so SCE-style Public Safety Power Shutoffs do not apply here; the reason to add a battery in Azusa is backup during any outage and using your own power at night.
Homes and roofs
Azusa has about 15,600 homes and roughly 55 percent are owner-occupied. The median home was built in 1970, so a large share of the housing stock is 1950s to 1970s single-story tracts on composition shingle, many now on their second or third roof. The exception is Rosedale, the master-planned community built on the old Monrovia Nursery site since the mid-2000s, where newer homes carry tile roofs and HOA architectural rules.
