Building permits in East Baton Rouge Parish — Louisiana's most populous parish — are issued by the City-Parish Department of Development for the City of Baton Rouge and the unincorporated parish, under a consolidated city-parish government, enforcing the statewide code. The cities of Baker, Central, St. George and Zachary issue their own permits.
This guide covers what requires a permit, MyGovernmentOnline (MGO), fees, trade permits, and inspections — so your East Baton Rouge Parish project stays on track.
East Baton Rouge operates a consolidated city-parish government: the Department of Development issues permits, plan reviews, and inspections for Baton Rouge and the unincorporated parish through MyGovernmentOnline (MGO), with an Expedited Plan Review option (three business days for residential, ten for commercial, for an extra fee). The cities of Baker, Central and Zachary issue all permits inside their own limits, and since 16 October 2024 so does the City of St. George. Check the flood zone early: the 2016 flood hit the parish hard.
Louisiana enforces a mandatory statewide building code — the Louisiana Uniform Construction Code (still often called the LSUCC). Adopted after Hurricane Katrina, the code law was re-enacted by Act 881 of 2026 as R.S. 37:3727 et seq., and the code is now overseen by the Louisiana Uniform Construction Code Commission (LUCCC) in the governor’s office, which replaced the former LSUCC Council. The code in force is the 2021 I-Codes (IBC, IRC, IEBC, IPC, IMC, IFGC) with Louisiana amendments, effective 1 January 2023, with the 2021 IECC from 1 July 2023 and the 2020 National Electrical Code; the 2024 I-Codes and the 2023 NEC take effect on 1 January 2027. Parishes and municipalities enforce only the statewide code (R.S. 37:3737) — local jurisdictions administer permitting and inspections. The City-Parish reviews commercial plans itself and also asks for the State Fire Marshal’s plan review letters; the State Fire Marshal reviews plans for life safety on buildings other than one- and two-family dwellings (R.S. 40:1574).
