  • Winter design temperature: 26 °F (Snohomish 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 4C: 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.

Questions

Electrical takeoffs in South Snohomish County

Do you do electrical takeoffs for houses in Lynnwood?

Yes. Upload the plan set for a house anywhere in south Snohomish County (Lynnwood, Edmonds, Mill Creek, Mukilteo, Bothell and Mountlake Terrace), or anywhere else. Nothing has to be built yet: we measure the house on the plans.

What design numbers apply in Snohomish County?

Snohomish County publishes energy code climate zone: 4C; winter design temp.: 26 °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 South Snohomish County?

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.
