Baton Rouge building & ADU permits
Recent permit activity, updated continuously.
Baton Rouge is Louisiana's capital and second-largest city, permitting jointly with East Baton Rouge Parish. Its open-data permit feed is one of the few that publishes BOTH the property owner and the contractor of record, so Igni can tell a genuine owner-builder project from a contractor-run job rather than inferring it from a missing field.
Igni is tracking 358 residential and building permits in Baton Rouge, LA — including 1 classified accessory-dwelling-unit (ADU) filing. The most active ZIP is 70806. The most recent filing Igni tracked was Sep 29, 2026. All records come from data.brla.gov (Socrata), an official government open-data feed, and are refreshed continuously.

Counts are permits issued per calendar month as Baton Rouge 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.
