What's inside
Built to be useful before you sign anything.
- Per-square-foot cost ranges for cosmetic, mid-depth, and down-to-the-studs remodels across WA markets.
- Soft-cost realism: architecture, structural / seismic engineering, WSEC compliance, surveys, geotech.
- Cascadia seismic retrofit on pre-1995 homes — foundation bolting, cripple-wall bracing, and chimney remediation.
- Pre-1980 home upgrade load: galvanized supply, cast-iron drain, knob-and-tube wiring.
- Realistic schedules including the multi-month Seattle permit reality on substantial scopes.
- Living-arrangement math: stay in versus move out, and Western WA rental carrying-cost reality.
- Construction loan and refinance dynamics that affect what scope is actually fundable.
Sample insight
Mid-depth whole-house remodels in Western Washington typically run $190–$340 per square foot in 2026; Seattle proper commonly $240–$420. Down-to-the-studs projects commonly land $350–$580 per square foot all-in once WSEC compliance, Cascadia seismic detailing, and Seattle permit timelines are accounted for. (Estimate based on 2024–2025 Washington permit and bid data.)
Independently compiled by BuildMatch AI's research team. Cost figures are estimates based on industry-typical Washington pricing for 2026 and should be validated against your specific project scope.
