What makes Walnut different.
Walnut is a small but premium SGV city known for its excellent schools and well-maintained custom homes. The housing stock is predominantly 1980s-2000s single-family on quarter-acre+ lots, often with three-car garages and pool/spa equipment. Walnut homeowners are typically tech-forward — strong demand for whole-home smart automation, structured cabling for home offices, and dual-EV charger installations. We pull permits with the Walnut Building Department and coordinate Edison interconnection for solar-paired systems.
Local conditions we see
Many homes have generous square footage but undersized 150A panels — common upgrade target. Pool/spa equipment frequently needs dedicated GFCI subpanels. Newer subdivisions sometimes have aluminum SER feeder cable that needs proper antioxidant treatment at terminations.
Who issues the permit, and what we handle.
Electrical permits in Walnut are handled by the City of Walnut Building & Safety Division (Community Development). Walnut's Building & Safety Division handles plan review, permits, and inspections at City Hall, and its page links an EV charger checklist and expedited EV charging station permit information. Requirements change, so confirm for your property. Kilowire pulls and manages the permit for the work we do.
Most Walnut addresses are served by Southern California Edison, but your bill shows your actual provider. Meter, service drop, and transformer work on the utility side is scheduled by the utility. Timing varies; confirm for your property.

Questions we hear in Walnut.
How does an EV charger permit work in Walnut?
The city's Building & Safety Division publishes EV charger guidance and a checklist. We prepare the load information and equipment details, pull the permit, and schedule the inspection. Confirm the current checklist for your address.
Can a 150A panel support two EV chargers?
Maybe, but only a load calculation can say. If the panel is short on capacity, load management such as an EVEMS can share power between chargers, or a service upgrade may be needed. We calculate before we quote.
What does pool or spa equipment need electrically?
Pool and spa circuits have specific GFCI and bonding requirements in the California Electrical Code, and adding them usually involves a permit. A dedicated subpanel is common but not always required; we confirm for your property.
What should be checked on aluminum feeder cable?
Aluminum conductors need connectors listed for aluminum and correct torque at each termination, following the manufacturer's instructions. We inspect terminations when we open the panel and report what we find.
Does smart home or structured cabling work need a permit?
Low-voltage work is treated differently from line-voltage work, and the rules vary by jurisdiction. If the project includes new circuits, panels, or line-voltage devices, expect a permit; confirm with the city for your scope.
