San Diego County pricing

House Rewiring cost in San Diego County

Whole-home rewiring is priced by square footage, wall and ceiling access, and how much of the house actually needs new wire. Knob-and-tube and aluminum branch wiring drive most rewire demand in San Diego County, often pushed by insurance non-renewal.

County baseline: $12,000–$28,000 whole-home; partial rewires from $3,500. Phased rewires 1 to 3 weeks, single rooms 1 to 2 days.

Coastal

$16,000–$32,000

Coronado, Pacific Beach, and Point Loma still have plenty of 1920s-50s beach bungalows running original knob-and-tube, and salt air degrades that old cloth insulation faster than it would inland. Plaster and lath walls are slow to open and patch, which is most of the labor cost. We phase these rewires room by room so the house stays livable, and that phasing adds time but keeps a family from moving out.

North Coastal

$17,000–$34,000

Oceanside, Carlsbad, Encinitas, and Del Mar carry a lot of 1950s-70s beach-adjacent construction where decades of salt-humid air in the wall cavities has degraded wiring insulation faster than an inland home of the same age. Homeowners here also tend to expect a full finish restoration, matched paint and trim, not just a patched wall, which raises the labor side of the job. This region and Coastal carry the highest bands in the county.

Central

$10,500–$29,000

City of San Diego neighborhoods like North Park, Hillcrest, and Old Town have the county's oldest and most varied housing stock, so this is the widest spread we quote. Pre-1920 pockets still have original knob-and-tube, while 1965-73 homes in La Mesa, Lemon Grove, and National City often carry aluminum branch wiring that insurers are flagging for non-renewal. Finished plaster walls slow access, and a partial rewire targeting just the failed circuits runs well under a full-house job.

North County Inland

$11,000–$24,000

Escondido, San Marcos, Poway, Rancho Bernardo, and Vista are mostly 1960s-80s tract construction, and a lot of it still runs the aluminum branch wiring that was standard through the early 1970s. Attic and wall access here is more open than coastal plaster homes, since most of this stock was built with drywall over conventional framing, which keeps rewire pricing closer to our county baseline. Cracked or brittle 1970s Romex in unremodeled homes is the other common trigger.

East County

$9,500–$23,000

El Cajon, Santee, and Lakeside have a mix of original construction from the 1950s-60s with additions bolted on through the 1980s, so it's common to find knob-and-tube in the original footprint and newer Romex in the add-on. We trace the boundary between the two systems and rewire only what's actually failing or unsafe, which keeps a lot of East County jobs on the lower end of the range compared to a full-house tear-out.

South County

$9,000–$22,000

South County splits the same way it does for panel work. Newer EastLake and Otay Ranch tracts were built to modern code and almost never need a rewire. Older west-side neighborhoods in Chula Vista and Imperial Beach fall in the 1965-73 window where aluminum branch wiring is common, and those are the jobs that call us. High-load circuits like the range and dryer usually get full copper replacement while lower-load circuits are handled with COPALUM crimps instead of tearing out the whole house.

Backcountry

$13,000–$30,000

Ramona, Julian, Alpine, Fallbrook, Valley Center, and Borrego Springs have cabins and custom homes built up in phases over decades, so it's common to find two or three eras of wiring in the same house. Travel time from San Diego adds to every visit, and rural jurisdictions sometimes schedule inspections less frequently than the coast, which can stretch the project timeline even when the wiring work itself is straightforward.
