Methodology

Where these numbers come from

This calculator applies published Puget Sound construction cost surveys and regional contractor pricing data, averaged for 2026. Base rates reflect typical projects by type; city multipliers account for labor-market and permit-fee differences relative to Everett (baseline 1.00). Last verified: January 2026.

It runs entirely in your browser: no AI, no data collection, nothing is sent anywhere. Deep dives: custom home costs · commercial costs · ADU costs.
