Whole House Rewiring Cost Calculator for Phoenix, AZ Homeowners
Plan your Phoenix, AZ rewiring budget with Phoenix House Rewiring. Adjust your home size, access, and project scope to see a cost range before scheduling an on-site estimate.
Your home & project
Start with the whole home's finished floor area. Amounts are in US dollars; results update as you change the details.
What goes into your estimate?
The calculator multiplies your floor area by each base rate and the access factor, adds the selected allowances, then applies contingency to each end of the subtotal. Defaults are illustrative budgeting assumptions, not a published price list or a guaranteed Phoenix average.
View the allowances and calculation details
- Access: open walls use 0.8× the base rewiring cost; finished walls with attic access use 1.0×; limited access uses 1.3×. The factor applies only to branch-circuit rewiring.
- Panel: retaining the panel adds $0; including panel work adds $2,500-$6,500; an undecided scope adds $0-$6,500. These allowances exclude relocation, trenching, and major utility service changes.
- Wall repairs: basic patching adds $0.50-$1.50 per sq. ft. of home floor area; patching and paint touch-up add $1-$2.50. This is a whole-project allowance, not a measurement of damaged wall area. "Budgeted separately" adds $0.
- Extra circuits: each additional standard appliance circuit adds $350-$750. Existing circuits are included in the base scope. Specialty equipment and long cable runs need separate pricing.
- Permits: the editable $500 starting allowance is counted once for the project. It is not an official city fee. Avoid adding it twice if a contractor's rate already includes it.
- Contingency: the chosen percentage applies to rewiring, panel work, repairs, extra circuits, and the permit allowance. Each line is displayed to the nearest dollar; small rounding differences can occur between the displayed line items and total.
Confirm the scope: aluminum or knob-and-tube wiring, block walls, attic access, and additions can change the work required. This estimate does not assess the condition of your wiring or determine whether a panel upgrade is needed.
Budget separately for: decorative fixtures, EV charging equipment, detached buildings, full-room repainting, hazardous-material remediation, temporary lodging, and any applicable taxes.
