A whole-house rewire is a significant investment, and the cost varies widely from home to home, which can make budgeting feel uncertain. Understanding the typical range, the factors that drive the price, and what a quote should include helps you plan realistically and avoid surprises. The single most reliable number always comes from a detailed quote for your specific home.

Here is how to budget for a whole-house rewire.

The typical cost range

As of 2026, a whole-house rewire commonly falls somewhere between about $8,000 and $30,000, with many mid-size homes landing around $10,000 to $20,000. On a per-square-foot basis, estimates range widely, often from roughly $3 to $10 or more per square foot, and higher for difficult homes. The spread is wide because the same house can draw very different quotes depending on its access, wiring condition, and whether a panel upgrade is needed.

Treat these as planning ranges, not a quote. Your actual number depends on the home in front of the electrician.

What drives the cost

Several factors move a rewiring budget up or down:

• Home size. Larger homes need more wire, outlets, and labor, though the cost per square foot often decreases with size as fixed costs spread out.
• Wall access. This is the biggest variable. Homes with accessible attics and basements let wire be fished with minimal wall openings, while finished basements, slab foundations, or plaster walls require more cutting and patching, which raises cost.
• Wiring condition and age. Older, deteriorated, or hard-to-reach wiring adds complexity.
• A panel upgrade. If the project includes replacing the panel or service, that adds to the budget.
• Circuit and outlet count. More circuits, outlets, and modern additions increase materials and labor.
• Permits and region. Permit costs and local labor rates vary by area.

What a quote should include

When comparing quotes, make sure they cover the same scope, since headline totals can be misleading. A thorough quote should account for the wiring, boxes, devices, the panel work if included, permits, and labor. Pay particular attention to whether drywall repair and finishing are included or excluded, since patching is a real cost that is sometimes left out of a low quote. Comparing detailed, itemized quotes rather than just bottom-line numbers protects you from surprises.

Consider a phased approach

If a full rewire is more than your budget allows right now, ask your electrician about a phased approach. Some homes can be rewired in stages, addressing the most urgent areas first and spreading the work and cost over time. A partial rewire or targeted fixes may also be appropriate in some cases, which an electrical inspection can help determine.

Tips for budgeting

To plan effectively:

• Get an assessment and detailed quote before setting your budget.
• Compare itemized quotes on the same scope, including wall repair.
• Ask what would drive the cost up or down for your home.
• Consider financing to spread the investment.
• Factor in the value: rewiring removes hazards, adds capacity, and supports insurability and resale.

Budgeting for a whole-house rewire starts with understanding the wide typical range, roughly $8,000 to $30,000 in 2026 with many mid-size homes around $10,000 to $20,000, and the factors that drive it, especially wall access, home size, wiring condition, and whether a panel upgrade is included. Compare detailed, itemized quotes on the same scope, watch for whether wall repair is included, and consider a phased approach or financing.
