  • Winter design temperature: 10 °F (Spokane County). The heating on your plans is sized for it, and heat pumps and electric heat are a big part of the service size.
  • Energy code climate zone 5B: the energy code sets what the plans ask for in heating, hot water and ventilation, and each of those is a circuit.
  • Washington electrical work follows the 2023 National Electrical Code, with state amendments. The 2026 edition takes over on December 31, 2026.

Sources: Spokane County: Spokane County Building Dept · Spokane: Spokane Municipal Code 17F.040.105 Design Criteria. Read 2026-09-28. Climate zones: Washington State Energy Code, Table R301.1. Every number is as the jurisdiction publishes it (its design criteria for houses, IRC Table R301.2(1)); a dash means it isn't published. Your lot can differ with elevation and exposure, so confirm it with the building department before you order.

Questions

Electrical takeoffs in Spokane & eastern Washington

Do you do electrical takeoffs for houses in Spokane?

Yes. Upload the plan set for a house anywhere in Spokane and eastern Washington (Spokane, Spokane Valley, Liberty Lake, Deer Park, Cheney and Colville), or anywhere else. Nothing has to be built yet: we measure the house on the plans.

What design numbers apply in Spokane County?

Spokane County publishes energy code climate zone: 5B; winter design temp.: 10 °F. The design on your plans should match them, and the takeoff follows your plans. Elevation and exposure can change them for your lot, so confirm with the building department.

Does a takeoff cost more in Spokane & eastern Washington?

No. The price is the same everywhere, and you see it before you pay. The 3D model is included, and each trade after the first in the same order is half price.

Is this an exact price?

No. It's an estimate built from your plans. Plans don't show code or inspector changes, the existing service, or devices added during construction. Anything built differently from the drawings won't be in the bid. We recommend a site visit to confirm measurements and conditions before you sign a contract or order materials.
