2026 remodeling cost per square foot
| Project type | Typical $/sqft | Notes |
|---|---|---|
| Whole home — cosmetic refresh | $15–$45 | Paint, flooring, fixtures, light repairs. |
| Whole home — full remodel | $60–$150 | Multiple rooms down to surfaces, some layout changes. |
| Whole home — gut renovation | $100–$220 | Back to studs: systems, layout, everything new. |
| Kitchen remodel | $100–$300 | Priced on kitchen area only — cabinetry and appliances drive it. |
| Bathroom remodel | $120–$350 | Small areas, high $/sqft: plumbing, tile and waterproofing. |
| Basement finishing | $30–$75 | Framing, drywall, flooring, lighting; more with a bath or wet bar. |
| Home addition | $100–$250 | New foundation + roof makes additions the priciest per foot. |
| Garage conversion | $40–$120 | Structure exists — cost is insulation, systems and finishes. |
| Deck (new build) | $25–$70 | Pressure-treated at the low end, composite at the high end. |

How to use these numbers
Cost per square foot is the fastest way to sanity-check a project before you have quotes. Multiply the area by the range for your project type, then refine: structural or layout changes push you toward the top of the range, keeping plumbing where it is keeps you near the bottom. Once you have a working number, price the specific project on our project cost & ROI pages and check what the spend returns at resale with the ROI calculator.
What makes cost per square foot vary
The range on any project type is wide because six factors push the number up or down — and they compound. Understanding them is the difference between a planning estimate that lands close to the final bill and one that misses by 40%.
Structural changes vs. cosmetic work
A cosmetic refresh — paint, flooring, lighting — costs $15–45 per square foot because you're working with the existing layout. The moment you move a wall, raise a ceiling, or cut a new opening, you introduce framing, engineering, header beams, and often structural permits. That alone can double the per-foot cost of a room even before finishes go in. If the wall carries load, you may need a temporary support system while the beam is set, adding both cost and time.
Plumbing and electrical density
Rooms packed with plumbing runs, drain lines, and electrical circuits cost more per square foot simply because more skilled labour and material is concentrated in a small area. A bedroom has a few outlets and a light; a bathroom has supply lines, a drain stack, a vent, GFCI outlets, an exhaust fan, and often heated floors. A kitchen adds gas lines, a dishwasher drain, dedicated 20-amp circuits for appliances, and under-cabinet wiring. That density is the single biggest reason kitchens and bathrooms dominate per-foot cost tables.
Permit requirements
Some jurisdictions require permits for nearly any work beyond painting, while others only trigger on structural, plumbing, or electrical changes. Permit fees themselves are usually modest ($200–2,000), but the inspections they require can add scheduling delays and sometimes force code upgrades — bringing an old panel up to current code, for instance, or adding fire blocking that wasn't required when the house was built. Those code-triggered extras show up in the per-foot number.
Accessibility of the space
A ground-floor room with easy access from outside is cheaper to renovate than a third-floor bathroom where every sheet of drywall rides up two flights of stairs. Basements add complexity if headroom is tight or moisture management is needed. Tight spaces slow trades down, and slow means expensive. If a dumpster can't park close to the work area, waste removal alone costs more per foot.
Material grade
The gap between builder-grade and premium finishes is enormous. Laminate countertops run $10–30 per square foot installed; natural quartzite or marble, $80–200. Vinyl plank flooring is $3–7 per square foot; wide-plank white oak, $12–20 before installation. When you see a project type quoted at $60–150 per square foot, the low end assumes mid-grade materials and the top end assumes high-end finishes throughout. The materials chapter of each of our project cost guides breaks out exactly where that spend goes.
Local labor market
Labour is typically 40–60% of a renovation's total cost, so regional wage differences move the needle substantially. A licensed electrician in a high-cost metro might bill $120–180 per hour; the same credential in a mid-size market, $70–100. Material prices are more uniform nationally, but labour is local — and in markets with tight trade availability, you pay a premium just to get on a contractor's schedule. Our per-city cost pages adjust for this.
Cost per square foot by room
The table above gives you ranges, but the why behind the numbers matters more for planning. Here is what drives each room's cost density.
Kitchens: $100–350 per square foot
Kitchens cost 3–5 times more per square foot than bedrooms because nearly every surface carries an expensive finish and the room concentrates the most trades. Cabinetry alone can account for 30–40% of a kitchen budget — a run of semi-custom cabinets in a 120-square-foot kitchen might cost $12,000–25,000. Add countertops ($3,000–8,000), a tile backsplash ($1,500–4,000), plumbing for the sink and dishwasher, electrical for dedicated appliance circuits, and the appliances themselves, and you're routinely spending $25,000–45,000 in a room that would cost $3,000–5,000 if it were a bedroom. A minor kitchen remodel that keeps the layout and replaces surfaces can cut the per-foot cost in half compared to a gut job.
Bathrooms: $150–350 per square foot
Bathrooms are often the highest cost per square foot of any room precisely because they're small. A 50-square-foot bathroom remodel at $15,000 works out to $300 per square foot — not because the finishes are exotic, but because plumbing rough-in, waterproofing, tile, a vanity, fixtures, and ventilation all compress into a tiny footprint. A full bathroom remodel in a slightly larger 75-square-foot space might cost $18,000–25,000, which looks better per foot ($240–330) but is actually more total spend. The per-foot metric can mask this distinction.
Basements: $30–75 per square foot
Finishing a basement is relatively affordable per foot because you're usually working with a large open area and adding partitions, flooring, lighting, and paint — not rerouting plumbing or replacing structural elements. The cost rises if you add a bathroom (which requires breaking the slab for drain lines), if moisture management needs a full waterproofing system, or if ceiling height is marginal and you need to address it. A straightforward 800-square-foot basement finish at $40 per foot is a $32,000 project — a lot of usable space for the money.
Bedrooms and living areas: $15–50 per square foot
These rooms are the cheapest to renovate per foot because the work is almost entirely cosmetic: paint, flooring, trim, lighting, maybe a closet system. There's no plumbing, minimal electrical beyond swapping fixtures, and no waterproofing. A 200-square-foot bedroom refresh at $25 per foot — $5,000 — can feel like a different room with new flooring, fresh paint, updated light fixtures, and new hardware.
When cost per square foot is misleading
Cost per square foot is a useful shorthand, but it can lead you astray in three common situations. Knowing when to trust it — and when not to — keeps your budget grounded.
Small rooms look disproportionately expensive
A 40-square-foot powder room remodel at $12,000 works out to $300 per square foot, which sounds alarming. But the cost is driven by a toilet, vanity, faucet, mirror, tile, and plumbing labour — items that cost roughly the same whether the room is 40 or 80 square feet. Doubling the room size wouldn't double the cost; it might add $2,000–3,000 in flooring and wall tile. Per-foot math makes small rooms appear far more expensive than they actually are in absolute terms.
Large open spaces look deceptively cheap
Conversely, refinishing a 1,500-square-foot open-plan living area might cost $30,000 — only $20 per foot. That looks like a bargain, but the total is still $30,000. The per-foot number is low because the space is big and the work is spread-out cosmetic updates, not because the project is inherently cheap.
Fixed costs don't scale with area
Every renovation carries fixed costs that are the same whether you're renovating 100 or 1,000 square feet: permit applications, dumpster rental, contractor mobilisation, project management, and design fees. On a small project these fixed costs might add $5,000–8,000 to a $15,000 job, inflating the per-foot number significantly. On a large project the same $5,000–8,000 is spread across a much bigger area and barely moves the needle. This is why a 50-square-foot bathroom can look more expensive per foot than a 200-square-foot kitchen even when the kitchen costs three times as much overall.
From per-foot estimate to real budget
Cost per square foot gives you a starting point. Here is how to turn it into a working budget that holds up against actual contractor quotes.
Step 1: Measure the space
Measure the room or area you plan to renovate — length times width for each section, summed. Use the interior dimensions, not the exterior footprint. If the space is irregular, break it into rectangles and add them up. For a whole-home project, use the gross interior square footage minus areas you won't touch (garage, unfinished attic, etc.).
Step 2: Multiply by the range
Take your square footage and multiply it by both the low and high end of the range for your project type from the table above. That gives you a planning corridor — for example, a 120-square-foot kitchen at $100–250 per foot suggests $12,000–30,000. Where you land in that range depends on the six factors covered above: scope, trade density, permits, access, materials, and local labour costs.
Step 3: Add 10–15% contingency
Every renovation turns up surprises — water damage behind tile, wiring that doesn't meet code, a subfloor that needs replacing. Budget 10% contingency for cosmetic projects and 15% for anything involving structure, plumbing, or electrical. This is money you hold in reserve, not money you plan to spend. If you don't use it, it becomes your buffer or goes back to savings. Our renovation budget calculator builds this contingency in automatically.
Step 4: Cross-check against project cost guides
The per-foot estimate is a top-down number. Cross-check it against a bottom-up breakdown. Our project cost guides show what's typically included for each renovation type — materials, labour, permits, design — with line-item ranges. If your per-foot estimate says $25,000 but the line-item breakdown totals $32,000, the discrepancy usually means your scope is more involved than the average for that project type.
Step 5: Get 2–3 quotes
No calculator replaces real quotes from contractors who have walked the space. Get at least two, ideally three, detailed quotes that break out labour, materials, and allowances separately. Compare them against your per-foot estimate and the cost guide to spot outliers — a quote that's 50% below the range is more likely to be missing scope than offering a genuine deal. The Planner Pro spreadsheet includes a three-quote comparison tab built for exactly this step.
Frequently asked questions
How much does it cost to renovate a house per square foot?
In 2026, a cosmetic refresh runs about $15–45 per square foot, a full remodel $60–150, and a gut renovation $100–220. Kitchens and bathrooms cost far more per foot ($100–350) because plumbing, cabinetry and tile concentrate cost in a small area.
Why do kitchens and bathrooms cost so much more per square foot?
Cost per square foot rises with the density of expensive trades. A bedroom is mostly paint and flooring; a bathroom packs plumbing, waterproofing, tile, ventilation and fixtures into 50 square feet.
Is cost per square foot a reliable way to budget?
It's a good first-pass sanity check, not a quote. Use it to size the project, then price the actual scope line by line — our free worksheet and the project cost guides break down what's typically included.
Does renovating cost more per square foot in expensive cities?
Yes — labour is the biggest driver, so high-cost metros like San Francisco, New York, London or Sydney typically run 20–50% above national ranges. Our per-city cost pages adjust for this.
