Short answer: in 2026, remodeling a house in New Jersey or on Pennsylvania’s Main Line costs roughly $100–$200 per square foot for a mid-level remodel and $200–$350 per square foot for a full gut renovation. Cosmetic refreshes start around $40 per square foot; luxury and historic renovations can pass $500.
“How much does a home remodel cost?” has a frustrating answer — it depends — but the things it depends on are predictable. This guide gives the per-square-foot ranges we see on real projects in South Jersey and the Main Line, what they look like for a whole house and room by room, and what pushes a project to the top or bottom of the range.
How Much Does a Home Remodel Cost in 2026?
For a whole-house remodel, most homeowners in our markets spend between $200,000 and $700,000. Where you land depends on three things: how much of the house is touched, whether the layout and systems change, and the age of the house.
Partial remodels — a kitchen, two bathrooms and new flooring, for example — are far more common than full renovations, and are usually better priced room by room using the table further down.
Home Remodel Cost Per Square Foot by Level
| Remodel level | Cost per sq ft | What it includes |

| Mid-level remodel | $100–$200 | Kitchen and bathrooms updated, new flooring and trim, some electrical and plumbing upgrades, minor layout changes. |
| Full gut renovation | $200–$350 | Taken back to the studs: new layout, systems, insulation, kitchen, baths and finishes throughout. |
| Luxury or historic gut | $350–$500+ | Structural changes, custom millwork and cabinetry, premium finishes, or period-matched work on a historic home. |
Whole-Home Remodel Cost by House Size

Remodel Cost Per Square Foot by Room
Per-square-foot cost is not even across a house. Kitchens and bathrooms concentrate plumbing, electrical, cabinetry and tile, so they cost several times more per square foot than a bedroom or living room.
| Space | Typical cost | Cost per sq ft | Full guide |
|---|---|---|---|
| Kitchen | $30,000–$110,000+ | $200–$450+ | Kitchen remodel cost |
| Bathroom | $15,000–$75,000+ | $300–$700+ | Bathroom remodel cost |
| Basement finish | $65,000–$160,000+ | $45–$140+ | Basement remodel cost |
| Living areas & bedrooms | Varies | $40–$120 | — |
| Home addition (new space) | $60,000–$400,000+ | $250–$400 | Home addition cost |
What Drives Remodeling Cost Per Square Foot
Layout changes
Keeping plumbing and walls where they are is the single biggest way to control cost. Moving a kitchen, relocating a bathroom or removing a bearing wall adds engineering, permits and trades.
The age of the house
Pre-war homes in Haddonfield, Moorestown and along the Main Line regularly need wiring, plumbing and framing work once they are opened. That cost is real and has to be done before finishes go in.
Systems
A new electrical service, HVAC sized for the house or replacing galvanized supply lines can add tens of thousands of dollars on its own, and is easier to do during a remodel than after.
Finish level
Semi-custom versus custom cabinetry, porcelain versus natural stone, builder-grade versus designer fixtures — finish choices alone can move a kitchen or bathroom by 50% or more.
Permits and design
Design, engineering and permit fees typically add 8–15% to a remodel. On a design-build project they sit inside one contract rather than arriving as separate bills.
How to Calculate Your Home Remodel Budget
- Measure the area you are remodeling — not the whole house unless the whole house is changing.
- Pick the level from the first table that honestly matches the scope.
- Price kitchens and bathrooms separately using the room table; they skew any whole-house average.
- Add design and permits at 8–15%.
- Add contingency: 10–15% on a newer house, 15–20% on a pre-1950s house.
Example: a 2,200 sq ft colonial with a full kitchen, two bathrooms and a mid-level refresh of the rest might be priced as a $90,000 kitchen, two $45,000 bathrooms, 1,800 sq ft at $120 per square foot ($216,000), plus 10% design and permits and 15% contingency — roughly $500,000.
Remodel or Add On?
If the problem is that the house is too small, remodeling cannot create room that is not there. An addition costs more per square foot — $250–$400 — but it adds space rather than rearranging it. Many of our projects do both: an addition for the new kitchen or primary suite, and a remodel of the rooms it connects to. See whole-home remodeling and our home addition cost guide.
Home Remodel Cost FAQ
How much does a home remodel cost per square foot in 2026?
In New Jersey and on Pennsylvania’s Main Line, a cosmetic refresh runs about $40–$80 per square foot, a mid-level remodel $100–$200, a full gut renovation $200–$350, and a luxury or historic full gut with structural changes $350–$500+ per square foot.
How much does it cost to remodel a 2,000 sq ft house?
A mid-level remodel of a 2,000 sq ft house typically runs $200,000–$400,000, and a full gut renovation $400,000–$700,000. A cosmetic refresh of the same house can come in around $80,000–$160,000.
Is it cheaper to remodel or build an addition?
Per square foot, remodeling existing space is usually cheaper than adding new space, which runs $250–$400 per square foot. But if the house is simply too small, remodeling cannot create room that is not there, and an addition is often the better long-term spend.
What is the most expensive part of a home remodel?
Kitchens and bathrooms carry the highest cost per square foot because they concentrate plumbing, electrical, cabinetry, tile and fixtures. Structural changes, such as removing bearing walls, and upgrading old electrical and plumbing systems come next.
Why do older homes cost more per square foot to remodel?
Opening walls in a pre-war home regularly finds outdated wiring, galvanized plumbing, plaster that must be patched to match and framing that needs reinforcing. That work has to be done before finishes, and it is a large share of the budget on many Main Line and Haddonfield homes.
How much contingency should I budget for a remodel?
Plan on 10–15% of the construction cost on a newer home and 15–20% on a house built before the 1950s, where hidden conditions are more likely.
