What Does a Whole-House Remodel Cost in 2026?

A Treasure Valley Pricing Guide

A whole-house remodel is the project that scares homeowners most, and often, paradoxically, the project that makes the most financial sense.

If you love your lot, your location, and your home’s footprint, but the house itself is dated, broken up by old floor plans, or running on 1970s mechanical systems, a whole-house remodel in Boise is usually 20–40% cheaper than tearing down and rebuilding, and dramatically cheaper than moving to an equivalent newer home in the same neighborhood.

Here’s what those projects actually cost in the Treasure Valley in 2026.

What "Whole-House Remodel" Actually Means

Boyd Remodeling and Construction defines a whole-house remodel as a project that touches most or all of the home, typically involving:

A new or significantly updated kitchen
All or most bathrooms remodeled
Some level of layout reconfiguration — walls moving, openings widened, traffic flow improved
Flooring throughout
Updated electrical, plumbing, and often HVAC
Refreshed or replaced windows, interior doors, trim, and millwork
Interior and often exterior paint
Sometimes structural work or a home addition layered on

It’s not a paint-and-flooring refresh. It’s a full reset of how the home functions and feels, without the cost or disruption of new construction.

Per Square Foot Reality Check

Across the Treasure Valley in 2026:

Scope	Cost Per Sq Ft
Cosmetic-heavy whole-house	$100–$200/sq ft
Mid-scope whole-house	$175–$400/sq ft
Full gut and remodel	$250–$650/sq ft
New custom construction	$275–$500/sq ft + land, site work, landscaping

For a 2,400 sq ft home in Eagle, Boise, or Meridian, a real whole-house remodel typically lands between $350K and $750K, depending on scope and finish level.

Why the Range Is So Wide

Whole-house remodels are scope-driven more than size-driven. Two 2,500 sq ft homes can have wildly different budgets because:

Layout changes drive cost. Opening up a closed 1970s floor plan, relocating a kitchen, reworking traffic flow, involves structural engineering, beam installation, and HVAC/plumbing/electrical rework throughout. Add $50K–$150K vs. a cosmetic version of the same project.
Mechanical systems. If your existing electrical panel is 100-amp, your plumbing is galvanized, or your HVAC is at end of life, all of these typically get replaced. Total mechanical replacement on a 2,500 sq ft home: $50K–$100K.
Bathroom and kitchen count. Each additional full bath adds $40K–$80K to total scope.

Finish level. Builder-grade vs. premium finishes can swing a whole-house budget by 30–50%.

Where the Budget Actually Goes

For a representative $475K, 2,200 sq ft whole-house remodel:

Kitchen: $105K–$140K
Master bath: $85K–$105K
Two secondary baths: $50K–$90K combined
Flooring throughout: $30K–$55K
Electrical (rewiring, new panel, all new fixtures): $25K–$45K
Plumbing (repipe if needed, all new fixtures): $20K–$40K
HVAC updates or replacement: $15K–$30K
Windows (if replacing): $25K–$50K
Drywall, paint, trim, doors: $40K–$65K
Design, permits, engineering: $20K–$35K
Project management and trade coordination: $55K–$85K

The Phases of a Real Whole-House Remodel

This is the most logistically complex project in residential construction. Phasing matters.

Discovery and design: 14–24 weeks. Architectural drawings, structural engineering, mechanical design, full selections, fixed-price scope. See our full process here.
Permitting: 8–14 weeks.
Construction: 24–48 weeks. Most clients move out for at least part of this.

Total: 12–20 months from first call to certificate of occupancy.

Live-In vs. Move-Out: What to Expect

For cosmetic-heavy whole-house projects with no major structural work and phased kitchen and bath work, clients sometimes live in the home for the full project. For full-gut projects, we always recommend moving out. The cost of a 6–9 month rental ($15K–$30K) is dramatically cheaper than compressed timelines, stressed families, and on-site decisions made under pressure.

Per Square Foot Reality Check

Boise, Eagle, and established neighborhoods across Meridian, Nampa, and Star include a significant number of homes built between 1950 and 1990. When we open the walls, we routinely find:

Knob-and-tube wiring, aluminum wiring, or undersized panels
Galvanized plumbing supply lines at end of life
Cast iron drain stacks with rust-through
Asbestos in vermiculite insulation, popcorn ceilings, or old flooring adhesive
Undersized framing for current loads
Foundation cracks or settlement

None of these are deal-breakers. All of them are predictable. Our pre-construction discovery process is specifically designed to identify these conditions before we break ground, eliminating the surprise change-order costs that blindside homeowners mid-project with other contractors.

Whole-House Remodel vs. Teardown and Rebuild

We get this question regularly. Here’s the math:

Remodel a 2,400 sq ft home: $400K–$750K
Tear down and build new (same footprint): $700K–$1.2M, plus demolition cost, plus starting from zero on timeline

If your existing foundation, framing, and roof are sound, a remodel almost always wins on cost. If they’re not, or if the layout you want is fundamentally incompatible with the existing structure, a teardown can be the smarter long-term move. We give clients honest assessments of both paths.

Whole-House Remodel Cost by City in the Treasure Valley

We serve homeowners across the region. Home age and condition vary significantly by city, which affects where hidden costs are most likely to surface:

Boise, ID — North End and East End homes frequently have older mechanical systems and original framing that requires attention.
Eagle, ID — Larger footprints and high-value neighborhoods are strong candidates for full-gut remodels and master suite additions.
Meridian, ID — 1990s–2000s construction is common; often in good structural shape but due for a full finish and mechanical refresh.
Nampa, ID · Kuna, ID · Caldwell, ID · Middleton, ID — Varied housing stock; pre-construction discovery is especially important in older neighborhoods.

Key Takeaways

A real whole-house remodel in the Treasure Valley starts around $200K for a cosmetic-heavy smaller home and scales to $1.2M+ for a full-gut renovation.
Most projects land between $350K and $750K.
Scope, not square footage, is the primary cost driver. Layout changes and mechanical replacement are the biggest budget movers.
A whole-house remodel is typically 20–40% cheaper than tearing down and rebuilding.
Expect 12–20 months from first call to certificate of occupancy.
Older homes (1950–1990) carry higher risk of hidden conditions; a thorough pre-construction discovery process is non-negotiable.

The Bottom Line

A real whole-house remodel in Boise and the Treasure Valley in 2026 starts around $200K for a cosmetic-heavy refresh and scales to $1M+ for a full-gut renovation. Most projects land between $350K and $750K.

The decision isn’t really about the number. It’s about whether the home you have, on the lot you love, in the neighborhood you’ve chosen, is worth investing in for the next 10–20 years. For most of our clients, the answer is yes, and the math favors the remodel.

If you’re sitting on a home you love in a location you can’t replace, but a layout or finish level that’s holding you back, request a consultation or schedule a call with a remodeling expert. Bring your house, your wish list, and your questions. We’ll build the scope and the budget from there.
