Ohio Construction Estimating Services

Ohio has one building code. That sounds simple. It isn’t.

The 2024 Ohio Building Code is mandatory statewide and it’s based on the 2021 International codes — building, mechanical, plumbing and existing building, all effective March 1, 2024. Houses are under the 2019 Residential Code of Ohio, also statewide. So a shell in Cincinnati and a shell in Cleveland are priced against the same book.

What isn’t the same is who reads the book. Ohio doesn’t review your plans at the state level. Certified local building departments do it — a city, a county, or a regional department covering a few townships — and each one has its own fee schedule, its own turnaround and its own habits on what it kicks back. The code is one thing. The desk is a hundred things.

Then there’s the tax. In Ohio, you are the consumer. The Department of Taxation’s rule is that a contractor who buys materials for incorporation into real property “needs to pay sales or use tax on their purchase price,” and “contractors and home remodelers do not collect sales tax on their work.” So there’s no tax line on your invoice, but there’s tax inside every material cost, at 5.75% state plus whatever the county and transit authority add — anywhere from 5.75% to 8.75% depending on where the lumberyard is.

And under every one of those jobs is the frost. Cleveland’s published design criteria put the frost line at 42 inches, and the weathering category is SEVERE. That’s a deep footing, a thick foundation wall, ice-shield underlayment on every roof, and a concrete season that has a start and an end. Whoever prices Ohio like a Sunbelt slab-on-grade has never poured in February in Lorain County.

Every one of these has cost somebody real money. We see them monthly.

1. The local desk. Because the state certifies local departments instead of running its own, the plan-review clock and the fee are set by the jurisdiction, not by Columbus. Columbus itself charges $700 plus $7 for every 10 gross square feet over 1,000 on a commercial permit, effective January 22, 2026 — up from $650 plus $6 the year before. A new one-family dwelling is $1,100 flat, six inspections included. That’s one city. The next department over has a different sheet. Pull it before you carry a permit allowance.

2. The tax inside your materials. Nobody itemizes it, so nobody sees it. But 5.75% to 8.75% on every dollar of material is a real spread, and the county where the material is delivered decides it. Set up your exemption certificate correctly, or use a direct-pay permit, and know which county rate your suppliers are charging you. On a $1M material budget the difference between the low and the high rate is real money.

3. Prevailing wage on public work. Ohio’s prevailing wage law covers public improvements above a threshold the Department of Commerce adjusts every two years — $250,000 for new building construction and $75,000 for reconstruction and remodel at the last published figure. Miss it and the penalty is the wages owed plus 100% of those wages. If you bid a school, a library or a municipal building at open-shop rates, you’re going to find out about it after the award.

4. Winter. A 42-inch frost line means excavation and footings go deeper than a Southern estimator expects, and a SEVERE weathering category means the concrete mix, the masonry detailing and the roof underlayment all change. Add weather days for a December start. An Ohio schedule without them is a schedule you’re going to eat.

We don’t ask you to take our word for it. Sixteen real Ohio estimates are on this page — four in each of the four categories we work in. $62.4M of construction value across 116 pages of takeoff and pricing. Open them. Read the line items. See exactly what you get before you send us a single sheet.

Commercial Buildings — ground-up hospitality, retail and institutional.

Tenant Buildouts — interior fit-outs in existing buildings.

• Dick’s House of Sports, Youngstown – $2.6M (44512)
• Canton Boot Barn #363 – $807K (44718)
• Copley-Fairlawn Veterinary Clinic, Akron – $379K (44333)
• CAVA University Circle, Cleveland – $106K (44106)

Four building types. Cincinnati up to Cleveland, Columbus across to Youngstown. From a $106K restaurant fit-out to a $24M hotel. That range is the whole point — most shops price one lane and call it a service.

Look at the Hyatt House. $24M, eighteen pages, general conditions through electrical, with the sitework and demolition priced instead of allowed. That’s a full hospitality estimate, not a square-foot guess with a brand name on it.

Now look at the Dick’s job in Youngstown. $2.6M and twelve pages, and most of them are wall framing — exterior parapets, kicker clips, sound batts, acoustical sealant — because a big-box conversion inside an existing building is framing, doors and ceilings, and every one of those is a separate takeoff. Same estimator, same state, completely different estimate.

We estimate statewide. Here’s where the volume actually is.

Cincinnati. Cincinnati, West Chester, Mason, Loveland, Batavia, Hamilton, Fairfield and the Northern Kentucky side of the river. Eight of the sixteen estimates above are Cincinnati-area jobs — the Hyatt House, the Grandin Lane house, the Corbin Park house, the townhomes and the Bates Ave remodel among them.

Columbus. Columbus, Dublin, Powell, Westerville, Hilliard, Grove City, Delaware and Marysville. The state’s growth engine and the one with the freshest fee schedule — the Columbus numbers above are the January 2026 sheet. The Chinmaya Mission and the Miniso store are both here.

Cleveland. Cleveland, Lakewood, Parma, Westlake, Strongsville, Mentor and Beachwood. Forty-two-inch frost, SEVERE weathering, Exposure D within 600 feet of the lake. Four of the sixteen estimates — the Yeshiva High School, the Detroit Ave apartments, the West 41st Street house and the CAVA fit-out — are Cleveland jobs.

Akron and Canton. Akron, Canton, North Canton, Medina, Fairlawn and Stow. The Boot Barn and the veterinary clinic are both on this page.

Dayton. Dayton, Kettering, Beavercreek, Huber Heights, Clayton and Springfield. The 5 Story Apartments in Clayton is the largest multi-family estimate on the page.

Toledo and the northwest. Toledo, Bowling Green, Findlay, Lima and Sandusky. Lake-effect winters and the same statewide code.

Youngstown and the southeast. Youngstown, Boardman, Warren, Zanesville, Athens, Portsmouth and Wellston. Thinner sub markets and longer hauls — that shows up in durations, and it should show up in the estimate. The Dick’s conversion is down here.

Every one of those cities has its own page with local detail. Start there if you want the county-level specifics.

General contractors bidding hard-bid and negotiated work. Subs who need a takeoff that survives a scope review. Developers who want a real number before they commit capital. Architects who’d rather price a design now than explain a surprise at bid day.

Ohio added 11,200 construction jobs in the year to March 2026 — third-most of any state — and the biggest one-month gain in the country that March. That’s a lot of invitations going out. If you’re a GC in Ohio turning them down because you can’t get numbers out fast enough, you’re going to keep leaving work on the table until somebody else does the takeoff for you. That’s what our Ohio construction estimating services are built to fix. You send the plans. We send back a priced estimate with the quantities shown, in a format you can hand straight to a client or an owner.

We’re not a lead service and we’re not a software subscription. A person does the takeoff. Another person checks it. You can call and ask why a number is what it is, and get an answer.

What you’re hiring is a cost estimator who has already priced work under the 2024 OBC, at your county’s tax rate, on a 42-inch frost line, against your local department’s fee sheet. Not a national square-foot average with the word Ohio written on top.

Send us your plans. We’ll tell you what it costs.
