What’s different about Seattle
Seattle carries high labor and permitting costs, Cascadia seismic codes, and a wet maritime climate that together make it Washington's priciest market.
- Earthquake codes can require extra bracing and reinforcement.
- Moisture management and rot-resistant materials add cost in humid air.
- Permit fees and skilled-trade labor rates here run well above the national average — usually the single biggest cost driver.
How the cost is built
Siding cost is driven by wall area, material (vinyl is the budget option; engineered wood and fiber cement cost more), the number of stories, and trim around windows and doors. Tearing off old siding and repairing sheathing underneath adds to the total.
