Basement Finishing Cost: Chicago vs National vs Columbus
Updated
Short answer
Part of Framing and Drywall.
Side by side
The same source, Angi, publishes city pages for Chicago and Columbus. That makes them comparable with each other more than with HomeGuide's national page.
| Size | Chicago, IL | Columbus, OH | HomeGuide, national, open plan |
|---|---|---|---|
| 500 sq ft | $27,500 to $72,500 | $10,000 to $45,000 | $15,000 to $20,000 |
| 750 sq ft | $41,250 to $110,000 | $15,000 to $67,500 | No row published |
| 1,000 sq ft | $55,000 to $145,000 | $20,000 to $76,000 | $30,000 to $40,000 |
| 1,500 sq ft | $82,500 to $215,500 | $30,000 to $85,000 | $45,000 to $60,000 |
Sources: Angi, Chicago IL, dated April 20, 2026; Angi, Columbus OH, dated April 14, 2026; HomeGuide, updated February 6, 2026. Chicago figures are printed exactly as Angi shows them, including the top of its 1,500 sq ft row.
What the gap tells you
Chicago runs well above Columbus: at 1,000 sq ft the Chicago high end is $145,000 against $76,000 for Columbus. Angi's Chicago page puts labor at 50 to 70 percent of cost, which points to wages and the metro market. Columbus brackets HomeGuide's national range at both ends. Rockford is a smaller city than Chicago or Columbus and Winnebago County permit fees are set locally, but no source in our data measures a Rockford price, so we do not claim a number.
No cost guide publishes a Rockford figure (Angi, HomeGuide, Thumbtack and Fixr have no Rockford page), so every range on this site is a national average or a Chicago-area or Columbus, Ohio guide, and each one is labelled that way.
How to use these ranges
- Use HomeGuide's national range as the working budget.
- Treat Chicago as a ceiling, not a forecast.
- Use Columbus as a cross-check on a mid-cost Midwest market.
- Ask three local bidders for line-item bids and compare them to the lines on the cost page.
Permit costs differ locally
Permit fees are not a national number. Rockford prices from the total reported value of the work; Loves Park and Winnebago County use $60.00 per square foot for a finished basement. Angi's Chicago page puts permits at $1,000 to $5,000, versus HomeGuide's $200 to $1,000. See the fee guide.
For per-foot ranges see that guide, and for a worked size see the 1,000 sq ft guide.
What to ask local bidders about their labor
Because labor is half or more of the cost in Angi's Chicago page and $6 to $20 per square foot in HomeGuide's national one, the labor line is where a Rockford bid will differ most from either. Ask each bidder for the labor and materials split, the number of people on the crew, and how long they expect the job to take. A bidder who prices the same materials but half the labor days should explain what they are skipping. A bidder who prices well above the others should name the reason.
Using a metro guide for the right purpose
A metro guide is a check on scale, not a price list. If a Rockford bid for a 1,000 sq ft finish is far above the Chicago range, something is wrong. If it is below HomeGuide's national low end, something is missing. Between those two bounds, the line-by-line comparison is the useful test.
Common misreads
- Treating the Chicago top row as a Rockford price. It is a metro table printed as published.
- Comparing HomeGuide's open-plan totals with a table that assumes more rooms.
- Reading the low-end national table as a quote. It is a reference that contradicts its own source's average.
- Ignoring the date. Each range here carries the date its source gives.

Quick answers
Is basement finishing cheaper in Rockford than Chicago?
Cost guides publish no Rockford price, so we cannot say by how much. Chicago's labor market is bigger and Angi's Chicago page runs well above the national range. Get local bids.
What does Columbus cost compare to?
Angi's Columbus, Ohio page runs $28 to $90 per square foot, close to HomeGuide's national $30 to $50 at the low end and higher at the top.
Why use Chicago and Columbus at all?
They are the metro guides published by the same source, so they are comparable with each other. We label every range by its market on the cost page.
Do permit costs differ between metros?
Angi's Chicago page puts permits at $1,000 to $5,000 while HomeGuide's national range is $200 to $1,000, and each Winnebago County office has its own schedule.
