Renovation Cost Estimator

Estimate a kitchen, bath, basement or addition project by scope, finish level and region.

The project

Cabinetry, countertop and appliances are roughly half the budget and the whole of the decision.

sq ft

Typical for this scope is 200 sq ft. The floor area of the space itself, not the whole house.

Labor in Columbus runs 5% below the national median.

Finish level

Set this before you set the budget, because on the same footprint they are the same decision.

Where you are shopping

Cabinetry, countertop and appliance choices are what separate the numbers. Labor barely moves.

Layout and the house itself
Are the plumbing and appliances staying where they are
years

Drives how much contingency this project deserves. Older construction hides more.

Recommended for a 35-year-old house: 15%.

Kitchen remodel in Columbus

$35,500–$51,000

A 200 sq ft kitchen remodel at the mid-range finish level, with everything stays put. Construction is 83% of the budget and the permit and 18% contingency are the rest. Expect bids themselves to land between $29,500 and $42,500.

What actually causes the overrun

In residential work the overrun is almost never the thing you chose — it is what the demolition found and what the code now requires. The recurring four are: wiring or plumbing that has to be replaced once it is exposed, a code upgrade the permit triggers in rooms you were not renovating, a layout change agreed to verbally after the bid, and selections upgraded mid-job because the sample looked different in the room. The first two are why the contingency line exists. The last two are inside your control, and they are the ones that show up on the invoice as change orders.

Keeping the fixtures in place is doing a lot of work here

Holding the sink, the appliance walls and the drain locations where they are keeps the mechanical share of this job to $7,600. A new layout on the same footprint would add roughly $8,300 before a single upgraded finish.

What this estimate deliberately leaves out

Structural changes, code upgrades the work itself triggers, and hazardous material abatement are all excluded — they are real, common and impossible to price without seeing the house. Design and engineering fees are also outside this figure, and an addition or a suite will need drawings. Treat the range as what to expect from bids on an average-complexity project, then get three of them on one written scope.

What this assumes

  • Ranges reflect typical U.S. pricing by finish level for a project of average complexity.
  • Includes a contingency allowance, which every renovation budget requires.
  • Structural changes, code upgrades triggered by the work, and hazardous material abatement are excluded.

Important

Renovations of older homes routinely uncover knob-and-tube wiring, failed plumbing, asbestos or structural issues that trigger required upgrades. Budget a contingency of 15 to 20% and expect to use part of it.

Understanding the result

Finish level dominates the total

The same kitchen footprint can run $25,000 or $90,000 with identical labor. Cabinetry, countertop and appliance selections drive the difference. Set the finish level before you set the budget, because the two are the same decision.

Moving plumbing and electrical is the expensive part

Keeping fixtures and appliances in place holds costs down dramatically. Relocating a sink, a gas line or a panel means opening walls, new rough-in, additional permits and inspection. A layout change is almost always the largest avoidable line item.
