Whole-Home Remodel Cost in Seattle: 2026 Price Guide by Square Foot

A whole-home remodel is the one project where "how much does it cost" has the widest honest answer. The same 2,000-square-foot Seattle house can be a $140,000 job or a $650,000 job depending on what stays, what moves, and what we find in the walls. Here is how we price it, so you can place your own house on the map before anyone measures it.

The short answer: price per square foot

For Seattle, Bellevue, and the Eastside in 2026, whole-home remodels land in these bands:

Tier	2026 cost per sq ft	2,000 sq ft home	What it covers
Whole-home refresh	$70 – $120	$140,000 – $240,000	Every room touched: paint, flooring, lighting, trim, doors, one kitchen and bath update, no layout changes
Full interior remodel	$150 – $250	$300,000 – $500,000	New kitchen and all bathrooms, some walls moved, rewired and replumbed where opened, new windows, HVAC upgrades
Gut remodel / structural	$275 – $400+	$550,000 – $800,000+	Down to the studs, new floor plan, bearing walls and beams, full electrical and plumbing, insulation, roof or foundation work, high-end finishes

If a bid comes in far below the refresh band for a whole house, read it again. Either rooms are missing, or "remodel" means paint and fixtures. Both are fine projects. They are just not whole-home remodels, and they should not be compared to one.

Why whole-home pricing is not just the sum of the rooms

People often add up a kitchen remodel and a couple of bathroom renovations and expect the total to match. It usually comes in lower per room, and higher overall, for a few reasons:

• Shared mobilization. One permit set, one dumpster rotation, one crew on site for months. Per-room overhead drops 10 to 20 percent.
• Systems get done once. A panel upgrade, a new water heater, or a sewer line repair serves the whole house. These are the big line items that single-room projects skip and whole-home projects cannot.
• Everything connects. Open the kitchen wall and you are into the dining room. Re-route a bathroom drain and you are in the ceiling below. Whole-home scope means you fix what you find instead of patching around it.

The line items that decide your number

1. Structural changes

Opening a 1950s rambler into a great room means engineered beams, seismic hardware, and often a new footing. Budget $15,000 to $45,000 for structural work on a typical single-story, more for a two-story where loads stack. This is the single biggest swing between the middle and top tiers.

2. Electrical service and rewiring

Most pre-1970 Seattle homes still have a 100-amp panel and some mix of knob-and-tube, cloth-wrapped, or ungrounded wiring. A full rewire with a 200-amp service runs $18,000 to $35,000 for a 2,000-square-foot home. If you are adding an induction range, heat pump, and EV charger, this is not optional.

3. Plumbing and sewer

Galvanized supply lines get replaced with PEX for $6,000 to $14,000 whole-house. The number nobody expects is the side sewer: a scoped line with root intrusion or a collapsed clay section is $8,000 to $25,000 to replace, and the city will want it done before final inspection if we find it.

4. Windows and envelope

Replacing 15 to 20 windows with modern double-pane units runs $25,000 to $55,000 installed. Add insulation to the walls while they are open and you will feel it on every February gas bill for the next thirty years.

5. Kitchen and bath finish level

Inside the bands above, the kitchen and bathrooms are where finish choices move the total most. Semi-custom cabinets and quartz versus custom millwork and quartzite is a $30,000 swing in the kitchen alone. We walk through the tradeoffs in our guide to choosing countertop materials.

6. Permits, engineering, and design

A whole-home remodel in Seattle needs a building permit from SDCI plus electrical, plumbing, and mechanical permits. Fees, structural engineering, and drawings together run $8,000 to $20,000 depending on scope. Our permits guide explains what triggers what.

A real example: 1,900 sq ft Shoreline rambler

A 1962 three-bedroom, two-bath home, full interior remodel with the kitchen opened to the living room. Final cost was $372,000, broken down like this:

Scope	Cost
Kitchen (new layout, semi-custom cabinets, quartz, appliances)	$88,000
Two bathrooms (full gut, tile, new fixtures)	$74,000
Structural: bearing wall removed, flush beam, footing	$26,000
Electrical: 200-amp service, full rewire, lighting	$31,000
Plumbing: PEX repipe, new water heater	$14,000
Windows (14) and exterior doors (2)	$38,000
Flooring throughout, paint, trim, interior doors	$52,000
Insulation, drywall, HVAC ductless heat pump	$29,000
Permits, engineering, design, project management	$20,000

The owners had budgeted $320,000. The gap was the sewer line and the panel, both found in the first two weeks and both approved in writing before we touched them. That is the version of a surprise you want: early, priced, and your call.

Should you do it all at once or in phases?

Phasing feels safer and often costs more. Each phase carries its own mobilization, its own permit, its own dust protection, and its own disruption. Doing the kitchen this year and the bathrooms in two years typically adds 12 to 20 percent to the combined total. Phasing makes sense when cash flow demands it, or when you need to live in the house and cannot relocate for four months. If you can move out, one continuous project is almost always cheaper and faster. Our week-by-week timeline shows what that schedule looks like.

Does a whole-home remodel pay back?

In Seattle's market, a well-executed whole-home remodel on a dated house in a good neighborhood is often the difference between a home that sits and one that gets multiple offers. The ROI math is strongest when the house is structurally sound, the lot is good, and the interior is simply decades behind. It is weakest when you over-build for the street. Our ROI guide covers which projects hold value and which do not.

Getting a real number for your house

Every band above tightens the moment someone walks your house, opens the panel, looks in the crawlspace, and scopes the sewer. That first visit is free, takes about ninety minutes for a whole-home scope, and you leave with a realistic budget band and a sense of whether you are a refresh, a full remodel, or a gut.
