Rewiring a Bay Area house typically costs $15,000-$40,000, with larger homes or difficult plaster-wall access reaching $60,000 or more. The cost to rewire a house in the Bay Area depends most on square footage, wiring access, electrical panel condition, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-house rewire | $10,000 | $27,000 | $60,000+ | Typical scope, before major finish repairs |
| Price per square foot | $8 | $18 | $35+ | Access and wall construction affect rate |
| Electrical panel replacement | $2,000 | $3,500 | $6,000 | Usually priced separately or as an add-on |
Assumptions: Bay Area contractor pricing, permitted work, standard copper wiring, and ordinary access unless noted.
Typical Bay Area rewire prices by house size
A straightforward rewire in a smaller, accessible home may cost $10,000-$18,000. A 1,500- to 2,000-square-foot home often falls around $20,000-$40,000, while a 2,500-square-foot or larger house can reach $35,000-$60,000 or more. Rates are generally higher in San Francisco and other high-cost urban areas than in less dense parts of the region.
These estimates assume replacement of branch-circuit wiring, common switches and outlets, and standard code-required protection. They do not necessarily include extensive drywall or plaster restoration, a service upgrade, premium fixtures, or concealed damage. For a typical 1,500-square-foot home, budgeting about $27,000 is a reasonable starting point.
How wiring, labor, and permits shape the quote
Electricians usually price a rewire as a project, but the estimate reflects labor, materials, access, and inspection requirements. The following ranges are broad allowances, not fixed charges; some contractors combine several items into one total.
| Quote component | Low | Average | High |
|---|---|---|---|
| Wire, boxes, outlets, and switches | $2,000 | $5,000 | $10,000 |
| Electrician labor | $7,000 | $16,000 | $35,000 |
| Panel or circuit work | $0 | $3,500 | $8,000 |
| Permit and inspection fees | $300 | $900 | $2,000 |
| Wall opening and finish allowance | $500 | $2,000 | $8,000+ |
Electrical labor in the Bay Area commonly runs about $100-$200 per hour per electrician, though project bids may not show an hourly breakdown. Permits vary by city and project scope; the contractor should identify who obtains the permit and whether inspection fees are included. Ask for labor, panel work, permit fees, and wall repair to be identified separately.
Why plaster walls and old panels raise rewire costs
Access is a major cost driver. Open framing during a renovation can reduce labor, while finished plaster walls, tight crawlspaces, or a finished attic can require careful fishing, additional openings, and more hours. Homes built before the 1950s may also have brittle plaster, outdated wiring, or hidden alterations that complicate the work.
Capacity matters too. A home with a 100-amp panel may need a 200-amp service to support added circuits or modern loads; that can add roughly $2,000-$6,000, and overhead service changes or utility coordination may increase the bill further. Adding circuits for an electric range, heat pump, or EV charger changes the scope. A 1,000-square-foot accessible house can cost less to rewire than a smaller house with difficult walls and a panel upgrade.
How long a full-house rewire takes in occupied homes
A typical crew of two electricians may need about 5-10 working days for wiring in an accessible 1,500- to 2,000-square-foot home. Complex layouts, plaster, limited access, or inspection scheduling can extend the project to two or three weeks. Temporary power, moving furniture, and keeping rooms usable may add coordination costs even when they do not appear as separate line items.
For a rough labor comparison, 100-180 electrician hours at $100-$200 per hour implies $10,000-$36,000 in labor before materials and fees. This is a planning calculation, not a substitute for a site-specific bid. Confirm whether the quote includes cleanup, temporary power arrangements, and return visits after inspection.
What common rewire scenarios cost in Bay Area homes
A partial rewire can be appropriate when only a few circuits are unsafe or damaged, but an electrician must verify that the remaining system is compatible and code-compliant. A targeted job may cost $2,000-$8,000; replacing wiring throughout a single floor or a 700-square-foot area may run $8,000-$18,000, depending on access and circuit count.
For comparison, a 1,200-square-foot home with open basement and attic access might receive a $16,000-$24,000 quote. A 1,800-square-foot plaster-wall house needing a panel upgrade could be $28,000-$45,000. A 2,500-square-foot home with difficult access, multiple new appliance circuits, and extensive patching may reach $45,000-$65,000 or higher. Compare bids only after confirming that they cover the same circuits, panel work, and finish responsibilities.
Which extra charges can appear after walls are opened
Drywall or plaster patching and painting may be excluded from an electrician’s bid. Allow roughly $500-$3,000 for limited patching, or $3,000-$10,000 or more when many rooms need finish work. Lead-safe procedures in older homes, asbestos-related materials, concealed damage, and difficult attic or crawlspace access require separate evaluation and can add substantial expense.
Other additions may include new smoke or carbon monoxide alarms, grounded outlets, AFCI or GFCI protection, service upgrades, and circuits for appliances. Ask whether the price includes devices and final testing, and request written unit prices or change-order rates for work discovered during demolition. Unpriced exclusions are a common reason a low initial quote grows.
Ways to lower a Bay Area house rewiring bill
Scheduling the rewire while walls are already open for remodeling can reduce access and patching costs. Clearing work areas, providing safe attic or crawlspace access, and deciding outlet locations before work begins can also help avoid paid return visits. Keep the scope focused on required wiring and planned electrical loads rather than adding unneeded fixtures or circuits.
Get at least three licensed-electrical-contractor quotes based on an on-site inspection, a circuit list, and the same panel assumptions. Compare permit handling, inspection corrections, cleanup, patching, and warranty terms—not just the bottom-line price. If only one area has a problem, ask whether a permitted partial repair is safe and practical before authorizing a whole-house replacement. The most reliable savings come from clear scope and fewer surprises, not from skipping required safety work.
