Building permits across East Baton Rouge Parish — Louisiana's most populous parish — are issued by the City-Parish Department of Development under a consolidated city-parish government, enforcing the statewide LSUCC.
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 parish-wide through MyGovernmentOnline (MGO), with an Expedited Plan Review option (~3 business days for residential). The newly incorporated City of St. George and smaller cities (Baker, Zachary, Central) may handle some permitting — confirm jurisdiction. Flood-zone status is common after the 2016 flood.
Louisiana enforces a mandatory statewide building code — the Louisiana State Uniform Construction Code (LSUCC). Adopted under R.S. 40:1730.21 et seq. after Hurricane Katrina and administered by the Louisiana State Uniform Construction Code Council (LSUCCC) under the Office of State Fire Marshal (OSFM), the LSUCC adopts the 2021 I-Codes (IBC, IRC, IEBC, IPC, IMC, IFGC, IECC) with Louisiana amendments (effective Jan 1, 2023; 2024 editions under review) plus the National Electrical Code. Critically, no parish or municipality may adopt codes more or less stringent than the LSUCC — local jurisdictions administer permitting and inspections but enforce one consistent statewide code. Where a parish or municipality does not provide commercial plan review, the OSFM performs it.

East Baton Rouge Parish trade permits
Electrical, plumbing, and mechanical work each needs its own permit and appropriately licensed tradespeople.
Electrical permits
Required for service installations, panel upgrades, solar PV, EV chargers, and most wiring alterations — performed by a contractor licensed by the LSLBC (Electrical classification). Louisiana enforces the National Electrical Code statewide through the LSUCC; commercial electrical subcontracts over $10,000 require a license.
Plumbing & gas permits
Required for new plumbing, repipes, water-heater changeouts, fixtures, backflow, and gas/sewer connections — performed by a contractor licensed through the Louisiana State Plumbing Board and, for commercial work, the LSLBC (Plumbing classification).
Mechanical (HVAC) permits
Required for HVAC installations, changeouts, ductwork, and venting — performed by a contractor licensed by the LSLBC (Mechanical classification). Commercial mechanical subcontracts over $10,000 require a license.
Miscellaneous & specialty
Fencing, pools, decks, sheds, and patio covers may require special permits depending on size and utility hookups. Demolition, sign, and right-of-way permits follow separate tracks.
Verify contractor licensing. Louisiana consolidates contractor licensing under a single agency, the Louisiana State Licensing Board for Contractors (LSLBC). A commercial license is required for projects $50,000+ (classified Building, Electrical, Mechanical, Plumbing, Specialty); a residential license for new 1–4 family dwellings over $75,000; and a Home Improvement Contractor (HIC) registration for residential remodeling between $7,500 and $74,999. Electrical, mechanical, and plumbing subcontractors need a license when their commercial work exceeds $10,000. Under Act 422 (effective Aug 1, 2025), all roofing work now requires a separate LSLBC roofing license regardless of project value. Plumbers are also licensed by the Louisiana State Plumbing Board. Verify licenses at lslbc.gov.
