If you’re trying to pin down the cost of home renovation before you talk to a single contractor, here’s the honest answer: most homeowners spend somewhere between $100 and $400 per square foot, depending on how deep the work goes. A quick paint-and-flooring refresh sits at the low end. A full gut renovation of an older home sits at the top.
We’ve priced enough of these projects to know that the number people expect and the number they actually pay are rarely the same thing.
What Does a Full Home Renovation Actually Cost?
A basic renovation, new paint, updated fixtures, maybe new flooring usually runs $60 to $150 per square foot. A mid-range renovation, the kind most families choose, lands between $150 and $275. High-end work with custom finishes pushes past $400.
A common pitfall: homeowners budget for the renovation they want, not the house they actually have. Older homes almost always cost more once the walls come down.
For a 2,000 sq ft home, that mid-range tier typically totals $300,000 to $550,000. Larger homes scale up fast; a 3,000 sq ft renovation can easily clear $800,000 once finishes and structural work are factored in.
Why Does Renovation Cost Vary So Much Between Homes?
Two houses with identical square footage can have wildly different price tags. In our experience, the gap usually comes down to what’s hiding behind the drywall.
Older homes often carry outdated wiring, corroded plumbing, and little to no insulation. Newer builds skip most of that, so the money goes straight into finishes instead of infrastructure.
What Drives the Cost of Home Renovation Up or Down?
A handful of factors decide whether your project lands near the low end or the high end of any estimate.
Structural complexity matters first. Moving walls, raising ceilings, or altering a roofline adds engineering costs before a single finish gets chosen.
Location matters just as much. Urban renovations cost more than suburban ones, mostly because of labour rates, tighter lot access, and stricter permitting.
Material and finish choices are the easiest lever to control. Custom millwork and imported stone push a budget up fast; mid-range materials hold the line without sacrificing quality.
Do Older Homes Cost More to Renovate?
Yes, and it’s rarely close. Homes built before the 1950s often need full electrical rewiring, new plumbing, and retrofitted HVAC systems that were never part of the original design.
If your Home still has knob-and-tube wiring or galvanized plumbing, budget for replacement before you budget for finishes. Skipping this step is the most expensive mistake we see.
Room-by-Room Renovation Costs
Breaking the budget down by room makes planning far easier than working from one lump-sum number.
Kitchens typically run $25,000 to $80,000 depending on cabinetry, countertops, and appliances. Bathrooms usually fall between $10,000 and $40,000, with plumbing changes driving most of the swing.
Basements cost $70 to $180 per square foot to finish, more if waterproofing or a separate entrance is involved. Living areas and bedrooms stay cheaper, often $150 to $200 per square foot for cosmetic work.
How Much Should You Set Aside for Hidden Costs?
Set aside 10 to 20 percent of your total budget for surprises. In our tests across dozens of projects, this contingency gets used far more often than homeowners expect.
Common hidden costs include permit fees, structural engineering, temporary housing, and hazardous material testing. None of these show up in a basic contractor quote, so ask about them directly.
Is Renovating Worth the Investment?
Some renovations pay for themselves at resale; others don’t. Kitchens typically return 75 to 100 percent of their cost, bathrooms return 70 to 90 percent, and a finished basement suite can return well over 100 percent through rental income.
Cosmetic updates like flooring and paint offer solid but smaller returns, usually 70 to 80 percent. If you’re renovating purely to sell, prioritize the rooms buyers actually notice first.
Should You DIY or Hire a Professional?
Simple, low-risk tasks like painting or installing shelving are fair game for DIY. Structural work, electrical rewiring, and plumbing should go to a licensed professional every time.
A poorly executed DIY fix rarely stays cheap. It usually costs more to undo than it would have cost to do right the first time.
How to Budget for a Home Renovation Step by Step
Getting your numbers right up front saves you from mid-project stress later. Here’s the order we recommend:
- Define your project scope clearly before requesting quotes.
- Get at least three quotes from licensed contractors.
- Add a 10 to 15 percent contingency for hidden issues.
- Confirm what’s included versus excluded in each estimate.
- Factor in permits, design fees, and temporary housing if needed.
Homeowners who skip step four are the ones most likely to feel blindsided by a final invoice that looks nothing like the original quote.
Conclusion
The cost of Home renovation depends on far more than square footage. Your home’s age, your location, your material choices, and how much structural work is involved all shape the final number more than any single average ever could.
Treat every renovation estimate as a starting point, not a final answer. Build in a contingency, ask what’s excluded from your quote, and prioritize the systems behind your walls before you fall in love with finishes.
