What drives the cost in Washington
Washington runs well above the national typical range, with Seattle and the Eastside supporting high labor rates, demanding permitting and a strong integrator market. Sales tax generally applies to both equipment and construction labor in the state, which adds to the all in figure, and seismic bracing is worth specifying. Electricity is inexpensive thanks to hydro power, and the west side is damp while the east side is dry.
Tips for Washington buyers
- Confirm the integrator holds the state's low voltage license.
- Ask whether quotes include sales tax on construction labor, since it applies here in ways it does not in many states.
- If you buy equipment in Oregon, understand Washington's use tax obligations before assuming savings.
