Electrician in San Anselmo, Marin County
San Anselmo’s charming older housing stock brings real electrical needs — here’s how we serve them.
Quick Answer
Towery Electric serves San Anselmo with licensed C-10 work suited to the town’s older Ross Valley homes: panel upgrades, knob-and-tube and aluminum wiring assessment and remediation, generator and EV installs, and permitted work that keeps homes insurable and sale-ready. The area’s mature housing makes wiring-age assessment a frequent first step.

San Anselmo’s tree-lined streets and older homes are part of its charm — and part of what shapes the electrical work here. Mature housing means more wiring-age and capacity questions than newer areas. See all our Marin service areas for neighboring towns.
The HomesCharming and Older
Many San Anselmo homes predate modern electrical demand, so assessing whether the service and panel fit today’s loads is a common first step. A panel upgrade is frequently the foundation for adding AC, EV charging, or electrification. Our panel upgrade signs guide helps you self-assess.
Ross Valley housing stock — the older, often pre-1960 homes of San Anselmo, Fairfax, and Ross, many with original or early wiring that affects safety, insurance, and resale.
The WiringOlder-Home Considerations
In older homes we frequently find knob-and-tube or aluminum branch wiring, which affect safety and insurance. Our guides on knob-and-tube and aluminum wiring cover what we look for. The Insurance Information Institute explains the coverage impact.

Frequently Asked Questions
Do you serve San Anselmo, California?
Yes. Towery Electric provides licensed C-10 electrical service throughout San Anselmo and the surrounding Ross Valley, including panel upgrades, knob-and-tube and aluminum wiring assessment and remediation, generator and EV charger installation, lighting, and general residential work. San Anselmo’s older housing stock means wiring-age and capacity assessment is often the starting point. We pull permits and work to the current California Electrical Code, and you can verify our license with the CSLB using number 989290.
Why do San Anselmo’s older homes need electrical attention?
Many were built for a fraction of today’s electrical demand and may still have original or early wiring. Modern loads — air conditioning, EV charging, heat pumps, and today’s appliances — can exceed an older service, and aging wiring like knob-and-tube or early aluminum has safety and insurance implications. That’s why a capacity and wiring-age assessment is a common first step here: it establishes what your home can currently support and what, if anything, needs updating before adding load or selling.
What wiring problems are common in San Anselmo homes?
In homes of San Anselmo’s vintage we sometimes find knob-and-tube wiring, early aluminum branch circuits, ungrounded outlets, and undersized services. Not every older home has issues, but these are worth checking because they affect safety, insurability, and resale, and they tend to surface during a sale or insurance review regardless. Identifying them proactively lets you plan any remediation deliberately. An assessment tells you whether your specific home has these conditions or is in good shape for its age.
Do you pull permits for work in San Anselmo?
Yes. We pull the required permits and schedule inspections for electrical work in San Anselmo, working to the current California Electrical Code. Permitted work is especially important on established homes because it documents that upgrades were done correctly, protecting both safety and resale value. Unpermitted work tends to cause problems during a future sale or insurance claim, so handling it properly from the start is the sound approach for a home you may eventually sell in a market where buyers scrutinize such things.
Can you install generators and EV chargers in San Anselmo?
Yes. Standby generators are a common request given the Ross Valley’s PSPS exposure, and EV charger installation is increasingly frequent. Both begin with assessing your service capacity — particularly relevant in San Anselmo’s older homes — to determine whether the existing panel supports the new load or whether an upgrade or load management is needed. We handle the full scope from that capacity assessment through permitted installation and inspection, as part of our residential service in the area.
How do I get an estimate for electrical work in San Anselmo?
Call us to describe what you need and schedule a visit. For San Anselmo’s older homes especially, an on-site look at the panel, service, and relevant wiring produces a far more accurate estimate than a phone guess, because capacity and wiring age drive so much of the scope. We’ll walk the work with you, explain what’s needed and why, and provide a written estimate you can rely on. That’s the honest basis for pricing work on an established home whose electrical history may be partly unknown.
