What Folsom's homes mean for your electrical work
Housing in Folsom is newer than in Sacramento's older neighborhoods, with a median build year of 1997, though about 13% of homes were built before 1980. Homes from the 1980s and 1990s mostly missed the aluminum-wiring period, which the CPSC places between 1965 and the mid-1970s, and they may already have some GFCI outlets. They were built before AFCI breakers entered the code in 1999, so bedroom and living-room circuits usually lack arc-fault protection. The bigger issue today is capacity: a panel sized for 1990s loads may be full once you add an EV charger, heat pump, or induction range.

Local rules, utilities and conditions in Folsom
Folsom gets its electricity from SMUD, the Sacramento Municipal Utility District. For a panel upgrade or service change, the work starts with SMUD's project application, and SMUD's service rules say it won't connect service until the work passes inspection by the local building authority. Customers who replace a gas furnace or gas water heater with a heat pump may qualify for SMUD's Go Electric bonus of up to $2,000 for a panel and new circuits. EV owners can get up to $850 through SMUD Charge@Home and a 1.5-cent-per-kWh discount on usage between midnight and 6 a.m. For a downed or sparking line, call 911, then SMUD at 1-888-456-7683.
Electrical permits in Folsom come from City of Folsom Community Development Department, Building Services. Plan on a permit for a panel upgrade or replacement, new circuits, an EV charger, a generator transfer switch, or rewiring. Rules for small jobs vary; the City of Sacramento, for example, requires a permit for new installations and modifications of panels and outlets, so ask before work starts. The licensed contractor should pull the permit in their own name; check the license on the CSLB license lookup. CSLB warns that signing as an owner-builder makes you responsible for the whole job. SMUD and PG&E both wait for the inspection sign-off before reconnecting a new panel.
Folsom is on the flat valley floor, where hot summers keep air conditioners running hard. Central air is usually one of the biggest loads on a home's panel, so adding an EV charger, heat pump water heater, or induction range can push an older panel to its limit. Before you buy new equipment, ask an electrician for a load calculation. PG&E's planning guide shows that circuit-sharing devices and lower-wattage appliances can sometimes let a 100-amp home go electric without a new panel, which PG&E says can save $2,000 to $6,000.
Wildfire and flood notes for Folsom
About 28% of Folsom (about 5,293 acres) falls in a Moderate Fire Hazard Severity Zone on CAL FIRE/OSFM's March 2025 recommended map for local areas.
Wildfire season can bring planned power shutoffs to foothill communities like Folsom. PG&E sends Public Safety Power Shutoff alerts by phone, text, and email, and anyone can sign up for Address Alerts for a home they care about. If you use a generator, never plug it into a wall outlet or connect it to your panel without a transfer switch or interlock; PG&E and SMUD both warn that backfeeding can electrocute line workers. A permanent hookup needs a permit and inspection from City of Folsom Community Development Department, Building Services. Run portable generators outdoors at least 20 feet from the house, since the CPSC says nearly 100 people die each year from generator carbon monoxide.
About 10% of Folsom lies in a FEMA Special Flood Hazard Area (Zones A and AE, including about 2.5% regulatory floodway).
