Cincinnati building & ADU permits
Recent permit activity, updated continuously.
Cincinnati sits on the Ohio River in southwest Ohio and regulates ADUs locally. Its CAGIS open data is released to the public domain; some downtown records lack a ZIP, so Igni falls back to coordinate reverse-geocoding before applying typed ADU classification.
Igni is tracking 5,200 residential and building permits in Cincinnati, OH. The most active ZIP is 45202. The most recent filing Igni tracked was Oct 30, 2026. All records come from data.cincinnati-oh.gov — CAGIS (Socrata), an official government open-data feed, and are refreshed continuously.

Counts are permits issued per calendar month as Cincinnati publishes them to its open-data feed — not a complete census; a change in what the city publishes moves them too. The current month is left out, and the most recent months are provisional. A forecast is a statistical estimate with a range, not a prediction for any project. Informational only.

Typical, not guaranteed: individual permits vary with project scope, application completeness and plan-review workload. Days are calendar days from application to issuance; applications still pending are counted as not-yet-issued rather than dropped. Informational only, not legal advice.
