- CA SPECIFIC · SAN DIEGO COUNTY
What is different about electrical wiring and rewiring in California.
Some of what we do for electrical wiring and rewiring is shaped by the codes and conditions specific to California. Here is what tends to differ versus other states.
California code stack
California layers state amendments on top of the National Electrical Code through the California Electrical Code, plus the Title 24 energy code in Part 6 and additional requirements in other parts. The practical effect for electrical wiring and rewiring is that the rule set is denser than NEC alone. Energy compliance, fixture efficacy, lighting controls in some occupancy types, and electrification readiness all show up at inspection. The cities and unincorporated areas across San Diego County each enforce the same state code stack but have their own permitting offices and inspection scheduling. We track current cycles for the AHJs across our coverage area, so the scope we write for Coronado, La Jolla, El Cajon, Oceanside, or any of the other cities we serve reflects the rules that AHJ is actually enforcing right now.
Marine-air and corrosion
Coastal San Diego County sits in marine air for most of the year, and chloride-laden moisture is harder on metal hardware than most homeowners realize. Standard zinc-plated parts that hold up indefinitely inland will pit and rust visibly within a few years close to the coast. We default to corrosion-rated boxes, fittings, and fixtures on exterior runs in the coastal zone, and we look for early-stage pitting on existing exterior installations when we are walking a job. That is the difference between a fixture that lasts 20 years and one that needs replacement at 7. Small upgrade at install, big difference over the life of the home.
Seismic and electrification
Seismic bracing on panels, generators, and large equipment is part of how we install in San Diego. Equipment that is structurally anchored stays connected through the kind of routine shaking that cracks unbraced installs. Separately, the state push toward home electrification is real on the ground here: more heat-pump conversions, more EV chargers per household, more battery-ready service planning. We size service capacity with the next-decade load in mind when the homeowner is open to it, so the panel we install for electrical wiring and rewiring today is not the bottleneck on the next upgrade.

- WHO TO HIRE
Why hiring a licensed electrician matters.
For electrical wiring and rewiring, here's the honest comparison. We'd tell you the same thing if we weren't trying to win the job.
Keil Electric
A licensed electrician
Licensed electrician walks every job. Veteran-owned, family-run.
Permits pulled and inspections coordinated when required by the AHJ
5/10-year + lifetime warranty in writing. Parts and labor. Transfers with the home.
Fully insured + workers' comp on every crew
The price you sign is the price you pay
A handyman
Unlicensed for electrical
No state electrical license. Can do simple swaps but not panel work, rewires, or service upgrades.
No permits. Work won't pass inspection if the city audits it later.
No structured warranty. "Call me if something breaks" isn't enforceable.
If something they did causes a fire, your homeowner's insurance can deny the claim.
Cash discount may show up on the invoice.
DIY
Doing it yourself
Cheap, but only if everything goes right. Most electrical work involves load calc, code, and permitting.
A failed inspection means redoing the work. Selling the home later, the buyer's inspector flags it.
No warranty if something fails. Replacement is on you.
Live wiring is a real safety hazard. Most fatal home electrical accidents are DIY.
If you know what you're doing, fine. If you don't, call us first.
Rewiring in San Diego County usually starts with a specific trigger. An insurance inspection that flagged knob-and-tube or aluminum branch wiring. A renovation that opened walls and revealed conditions the homeowner didn’t know about. A real estate sale where the inspector’s report identified work to be done. The county’s wide range of housing eras means each trigger leads to a different scope.
Pre-1965 homes: knob-and-tube assessment
Coastal communities (La Jolla, Coronado, parts of San Diego central) and older inland neighborhoods (parts of El Cajon, La Mesa, Lemon Grove) include pre-1940 homes where knob-and-tube wiring is sometimes still in service. The wiring is not inherently unsafe but fails when buried in modern attic insulation, when modifications were made by non-electricians, or when the original system has been overloaded by additions.
1965-1973 aluminum branch wiring
Homes built or wired during the 1965-1973 era sometimes have aluminum branch wiring on 15-amp and 20-amp circuits. The CPSC has documented failure modes at terminations. Remediation options include COPALUM crimps, AlumiConn connectors, or replacement with copper. We assess and recommend the right path per circuit, not blanket-replace.
1970s shared-neutral kitchens
Mid-century kitchen circuits in San Diego County often use multi-wire branch circuits with shared neutrals. Modern loads (microwave, toaster, coffee maker, induction range) can overload an undersized neutral even when the breaker doesn’t trip. We test for neutral sizing during diagnostic visits.
Solar PV affects rewire scoping
Homes with existing solar PV require careful coordination during a rewire. The interconnect at the panel can’t be disturbed without coordinating with the solar contractor. We document the PV setup at the site visit and plan the rewire sequence to keep the PV interconnect intact.
Common questions for Electrical wiring and rewiring in San Diego, CA
How do I know if my home needs to be rewired?
Common signs: knob-and-tube or aluminum wiring, frequent breaker trips, two-prong outlets in main living areas, scorched outlet faces, warm switches, or a panel that has been pushed past its original capacity. An inspection visit confirms whether the work is repair-scope or rewire-scope.
Do you have to open every wall to rewire a home?
Not always. Skilled rewires use existing wall cavities, attic and crawl space access, and small fish-tape paths to minimize wall damage. We document the access plan room-by-room before quoting so you see the trade-off between cost, time, and patch work.
How long does a whole-home rewire take?
Typical single-family rewires run 1-2 weeks of on-site work depending on home size, finish complexity, and how many circuits need to be added. We confirm the timeline in the written scope.
Will the home have power during a rewire?
Most rewires are sequenced so the home stays usable during the project - circuits go offline one section at a time. We coordinate closely if there are health, work-from-home, or temperature constraints.
Is permit and inspection required for rewiring?
Yes for any rewire scope that touches the panel or new circuits. The exact permit path varies by city; we handle the permit application and inspection scheduling as part of the project.
How much does a house rewire cost?
A house rewire is bid by home size, wall access (open walls during a remodel cut labor significantly versus fishing through finished walls), and any code-correction items found during the walk. The price is in writing before any work starts.
Do you do whole home rewire jobs?
Yes. Whole home rewire is one of our largest scopes. We stage room by room so part of the home stays powered each day. Multi-day to multi-week timeline depending on size.
Do I need to move out during a rewire?
Not always. We can stage the work room by room and keep at least part of the home powered each day. For full rewires on smaller homes or when the panel is also being replaced, a few-day relocation is sometimes simpler. We tell you which path matches your home before quoting.
What about aluminum wiring?
Aluminum branch wiring (typically 1965-1973 era) has documented failure modes at connection points. We either replace the runs end-to-end or pigtail with copper using approved CO/ALR connectors, depending on the actual condition of the aluminum and the driver of the job (insurance, sale, code).
