Whole House Remodel Cost in Seattle (2026): Complete Budget Guide

A whole-house remodel can transform a dated or poorly functioning home into exactly what you want, often for less than buying new in Seattle’s expensive market. Here is a complete 2026 cost guide.

Whole House Remodel Cost Per Square Foot

In the Seattle area in 2026, whole-house remodels range widely by scope:

• Cosmetic refresh: $80 to $150 per sq ft (finishes, paint, fixtures, some systems)
• Mid-level remodel: $150 to $300 per sq ft (kitchens, baths, some walls, updated systems)
• Gut renovation: $300 to $550 per sq ft (down to studs, all new systems, layout changes)

Cost by Home Size (Gut Renovation)

• 1,500 sq ft home: $450,000 to $825,000
• 2,500 sq ft home: $750,000 to $1.4M
• 3,500 sq ft home: $1.05M to $1.9M

What Drives the Cost

• Structural changes and wall removal
• Full electrical and plumbing replacement (common in older Seattle homes)
• Kitchen and bathroom count and quality
• Hidden conditions: knob-and-tube wiring, asbestos, foundation issues
• Seismic upgrades triggered by major renovation

Budget a Contingency

Older Seattle homes hide surprises. Budget a 15 to 20% contingency for a gut renovation of a pre-1970 home.

Architect and Permit Costs

• Architect fees: 12 to 18% of construction cost
• Permit fees: 1 to 2% of project valuation
