Roughly 0.2M of these records come from 12 retired permitting platforms that Ohio jurisdictions have since replaced. That history stays in the data when a locality changes systems.

FAQ

Frequently asked questions

Are Ohio building permits public record?
Yes. Building permits issued by Ohio jurisdictions are public records. Each one publishes them in its own format and its own system, which is why a statewide view requires collecting and standardizing them jurisdiction by jurisdiction.
How do I look up a building permit in Ohio?
For a single property, the issuing jurisdiction's permit portal is the place to start, since permits are issued locally rather than by the state. For many properties at once, or for analysis across jurisdictions, a standardized dataset is the practical route: Builty holds 6.2M+ Ohio permit records in one consistent structure.
How far back does Ohio permit data go?
Ohio carries sustained coverage from 1997 to the present. Individual jurisdictions reach back further, and some records carry placeholder dates from legacy systems; those are identified as placeholders, so the stated window is the one the data actually supports.
Which Ohio city has the most building permits?
Columbus, at roughly 19% of state records, followed by Cleveland and Cincinnati.
What is the Ohio statewide system in the coverage table?
Some Ohio localities file through a shared statewide system rather than running their own portal. Those filings are collected as their own stream so they are not silently attributed to the wrong jurisdiction.
Can I get data for a single county or city?
Yes. Delivery can be scoped to any set of Ohio jurisdictions, project types, or date ranges, by API, bulk file, or ongoing feed.
