Use the portion of the home or unit receiving new circuits or rewiring.
Typical schedule
1.2 weeks
Inspections, drywall repair, and finish trades often extend the full project.
Notes
Profile
Targeted work
Load calculations determine whether the existing panel can accept new breakers.
Code-heavy
Small areas, high labor
Counter circuits, appliance feeds, and ventilation often need dedicated runs.
Duration
Multi-phase
Phasing around occupancy and drywall repair affects total project cost.
Labor
Fishing premium
Surface conduit can speed some runs at a different aesthetic cost.
Utility
Coordination
Service upgrades may require utility scheduling beyond the wiring crew.
Timeline
Hold points
Covering boxes before inspection can trigger costly rework.

The calculator applies illustrative all-in rates per square foot by wiring scope, adjusts for routing difficulty, adds panel coordination bands, and layers a device-density allowance. A regional labor multiplier produces a total split across wire and devices, electrician labor, and permits or fees. Utility service upgrades, trenching, and finish drywall are not itemized separately.
