How much does a whole house renovation cost?

A full whole house renovation costs $100,000–$500,000+ depending on home size, scope, and location. Light cosmetic updates (paint, floors, fixtures) run $15–$40 per sq ft. Mid-range renovations including kitchens and bathrooms run $40–$100 per sq ft. High-end gut renovations run $100–$200+ per sq ft.

Is it cheaper to renovate or buy a new house?

It depends on your market. In high-cost cities where new construction is scarce, renovating can be significantly cheaper per square foot. In markets with new builds readily available, buying new may make more sense for major renovations. Factor in your current mortgage rate vs. what you'd pay on a new purchase loan.

How long does a whole house renovation take?

A full gut renovation of a typical 2,000 sq ft home takes 6–18 months from design through final punch list. The design and permit phase alone can take 2–4 months. Cosmetic-only renovations can be completed in 8–12 weeks. The more you open walls and change layouts, the longer the project takes.

Whole House Renovation: What You're Really Signing Up For

A whole house renovation is one of the largest financial decisions a homeowner can make. Unlike a single-room remodel, a whole house project requires managing dozens of overlapping trades, a long timeline, and a budget that almost always has surprises. This guide helps you build a realistic budget and avoid the most common pitfalls.

Cost Ranges by Renovation Scope

Cosmetic Refresh ($15–$40/sq ft)

Paint throughout, new flooring, updated light fixtures, hardware, and minor bathroom updates. No structural work, no layout changes, no major plumbing or electrical. A 2,000 sq ft home: $30,000–$80,000.

Mid-Range Renovation ($40–$100/sq ft)

Kitchen remodel, bathroom remodels, new windows, HVAC replacement, electrical panel upgrade, and updated insulation. Some layout modifications. A 2,000 sq ft home: $80,000–$200,000.

Full Gut Renovation ($100–$200+/sq ft)

Everything down to the studs: new plumbing, new electrical, new HVAC, structural changes, premium finishes throughout. A 2,000 sq ft home: $200,000–$400,000+. In high-cost markets (New York, San Francisco), expect 30–50% higher.

Budget Breakdown by Category

Kitchen: $30,000–$100,000 (15–25% of total renovation budget)
Bathrooms: $15,000–$45,000 each (10–15% each)
Flooring: $8,000–$30,000 whole house
Windows and doors: $10,000–$40,000
Electrical: $8,000–$20,000
Plumbing: $8,000–$25,000
HVAC: $10,000–$25,000
General contractor markup: 10–20% of total project cost

The Contingency Fund: Non-Negotiable

Add a 15–20% contingency on top of your contractor's estimate. On a $200,000 renovation, that's $30,000–$40,000 held in reserve. This isn't pessimism — it's engineering. Hidden rot, asbestos, outdated wiring, and plumbing surprises appear in virtually every gut renovation. Contractors who tell you to skip the contingency are setting you up for financial stress mid-project.

Phasing a Whole House Renovation

If budget is a constraint, consider phasing the project over 2–3 years:

Phase 1: Systems (HVAC, electrical, plumbing) — unglamorous but essential
Phase 2: Kitchen and primary bathroom — highest ROI rooms
Phase 3: Secondary rooms, exterior, and landscaping

Make sure your contractor plans the phases to avoid redoing finished work. For example, run all rough electrical and plumbing before closing any walls, even if you're finishing rooms later.

Choosing the Right Contractor for a Whole House Project

Not every general contractor is equipped for a whole house renovation. Look for a GC with experience managing projects of similar scale and who has established relationships with all the trades your project needs. Ask for references from at least two whole house projects completed in the past two years. Browse experienced general contractors in your city to find vetted professionals for large-scale renovations.
