So you’ve got an older building in Ohio — maybe a gorgeous Victorian in a neighbourhood that’s seen better days, or a sturdy brick commercial property that’s just been sitting there, waiting. And someone mentioned there might be tax credits available for restoring it.
Good news: there are. And they can be surprisingly generous.
But here’s the thing — navigating Ohio’s Historic Preservation Tax Credit program can feel like reading a legal document written in a foreign language. What counts as “certified historic”? Does your house even qualify? What do they mean by “qualified rehabilitation expenditures”?
Let’s break it all down in plain English. No jargon. No fluff. Just the stuff you actually need to know.
(And if you’re already knee-deep in a preservation project and want someone who’s done this before, the team at K&K Construction works with historic properties across Ohio — worth a look.)
7 Things You Need to Understand About Ohio’s Historic Preservation Tax Credit
1. What This Program Actually Is (And Why It Exists)
Ohio’s Historic Preservation Tax Credit — often called the OHPTC — is a state program that provides owners with a tax credit of up to 25% of qualified rehabilitation costs when they restore a certified historic building.
That’s not a deduction. It’s a credit. Meaning it comes directly from what you owe in state taxes. Big difference.
The program exists because Ohio has thousands of ageing historic structures that are expensive to restore but culturally important to preserve. Without a financial incentive, many of these buildings would just… sit. Or get torn down. The credit tips the math enough that rehabilitation becomes more realistic.
Think of it as the state saying, “We want these buildings saved. We’ll share the cost with you.”
Quick tip: There’s also a federal Historic Tax Credit program (20% credit) that can sometimes be stacked with the Ohio credit — so the combined benefit can be significant.
2. What “Certified Historic Structure” Actually Means
This is where a lot of people get tripped up. Not every old building qualifies. The building has to be a certified historic structure, which means one of these things:
- It’s listed individually on the National Register of Historic Places
- It’s a contributing building in a National Register Historic District
- It’s been certified by the Ohio Historic Preservation Office (OHPO) as meeting the criteria
Here’s what that means practically: your 1920s Craftsman bungalow might qualify — or it might not, depending on whether it’s in a recognised district or individually listed. The first step is always finding out where your property stands.
You can search the National Register of Historic Places online or contact the OHPO directly. And if your building isn’t listed yet? There’s a process for getting it nominated, though that adds time and steps.
Real-world example: A friend of mine bought a 1910 brick commercial building in a small Ohio city. It was in a National Register Historic District — something she only found out by asking. That single fact opened the door to the tax credit. She had no idea.
3. The Difference Between Residential and Commercial Projects
This part is important, so pay attention.
The Ohio Historic Preservation Tax Credit has two tracks:
Commercial track: For income-producing properties (commercial buildings, rental properties, mixed-use). This is a competitive program — you apply, you’re scored, and credits are awarded based on ranking. There are application rounds throughout the year.
Residential track: For owner-occupied homes. This track is generally more accessible, with a credit of up to 25% of qualified rehab costs (capped at $10,000 per project, with some exceptions).
If you’re a homeowner living in your historic home and you want to restore it, the residential track is your path. The commercial track is generally for investors or developers working with income-producing properties.
The residential program is less talked about, honestly — but it’s real, and it’s worth knowing about if you own and live in a historic home in Ohio.
4. What Counts as a “Qualified Rehabilitation Expenditure”
Not every dollar you spend on your building counts toward the credit. The program cares about qualified rehabilitation expenditures — and the definition matters.
Generally, qualified expenses include work that:
- Preserves or restores the historic character of the building
- Is done to the building itself (not land, not furnishings, not parking lots)
- Meets the Secretary of the Interior’s Standards for Rehabilitation — a federal framework for how historic properties should be treated
What doesn’t count: acquiring the property, new additions that aren’t part of the historic structure, or personal property inside the building.
Here’s the nuance that trips people up: you can’t just gut the building and modernise everything. The point of the program is historic preservation, not just renovation. There are rules about what you can change and what you have to keep.
This is why working with someone experienced in historic building preservation in Ohio is so important — knowing what work qualifies (and what might disqualify your whole project) can save you a lot of grief.
5. The Application Process (And Why Timing Matters)
Okay, here’s where it gets a little bureaucratic. Bear with me.
For the commercial track, the process involves:
- Part 1 Application — Certifies the building as historic and describes the project
- Part 2 Application — Describes the work in detail before you start (this is important — you generally need approval before beginning significant work)
- Part 3 Application — Filed after completion to get final certification
The residential track is simpler, but still requires documentation and OHPO review.
The big thing to know: timing is critical. If you start significant work before getting your Part 1 approved, you risk disqualifying the project. This is one of the most common (and painful) mistakes people make. Don’t start the demo without understanding where you are in the process.
Pro tip: The OHPO staff are actually really helpful if you reach out before starting. They’d rather answer your questions up front than sort out a disqualified project later.
6. The Minimum Spend Requirement
There’s a threshold you have to hit for the project to qualify. For the commercial track, your qualified rehabilitation expenditures need to exceed your adjusted basis in the building (basically, what you paid for it minus depreciation). That sounds complicated, but your accountant can calculate it.
For the residential track, there’s typically a minimum expenditure threshold too — you can’t just replace a few windows and claim a credit.
The honest truth: this program is designed for real rehabilitation projects, not minor touch-ups. If you’re thinking about a significant restoration of a historic property, the math often works out well. If you’re doing small repairs, the credit probably isn’t accessible to you.
7. What the Credit Is Actually Worth — And What to Expect
Let’s talk numbers, because this is where it gets interesting.
For commercial projects, you can receive a state tax credit worth up to 25% of qualified expenses. On a $500,000 rehabilitation, that’s up to $125,000 in state tax credits. Combined with the 20% federal Historic Tax Credit, you’re potentially looking at 45 cents of tax benefit for every qualified dollar spent.
For residential owner-occupied projects, the credit is smaller — but it’s still real money back on a restoration that you’d be doing anyway.
One thing to be honest about: the commercial credit is competitive, and not every application gets funded. Credits are awarded in rounds, and demand can exceed availability. It’s not guaranteed money — it’s an application for money that may or may not be approved.
That said, successful projects have transformed entire neighbourhoods across Ohio. And if you’re serious about restoring a historic structure, it’s absolutely worth applying.
Quick Summary Table
| Commercial Track | Residential Track | |
|---|---|---|
| Property type | Income-producing | Owner-occupied home |
| Credit amount | Up to 25% of qualified costs | Up to 25% (capped at $10,000) |
| Competitive? | Yes — application rounds | Less competitive |
| Federal credit available? | Yes (20%) | Limited |
| Minimum spend? | Exceeds adjusted basis | Varies |
Key Takeaways
- The Ohio Historic Preservation Tax Credit offers up to 25% back on qualified rehabilitation costs for certified historic buildings
- Your building must be listed on the National Register of Historic Places (individually or as part of a district) to qualify
- There are two tracks: commercial (competitive, for income-producing properties) and residential (for owner-occupied homes)
- Not all renovation work counts — it must meet the Secretary of the Interior’s Standards and preserve historic character
- Start the application process before significant work begins — this is the most important timing rule
- The federal Historic Tax Credit (20%) can sometimes be stacked with the state credit for major commercial projects
- Reach out to the OHPO early — they’re helpful, and it’s better to ask questions upfront
Is Your Building Worth Pursuing This?
Here’s my honest take: if you own a genuinely historic property in Ohio and you’re planning a real rehabilitation project, this program is worth your serious attention. The credits are real, the savings can be significant, and the preservation work you do matters — both for the building and for the community around it.
But it takes patience, documentation, and working within a framework that has real rules. Going in without understanding those rules is how people accidentally disqualify themselves.
If you’re unsure whether your property qualifies or what the process looks like in practice, talking to someone who’s navigated it before makes a huge difference. The folks at K&K Construction have experience with historic preservation projects in Ohio — and that kind of hands-on knowledge is genuinely valuable when you’re trying to figure out if this path makes sense for your building.
Your historic building has a story. This program exists to help you keep telling it.
