ADU Construction · Beauregard County, Louisiana
Permit required
In Louisiana, a ADU Construction requires a building permit.
An accessory dwelling unit (ADU) always requires a building permit because it adds a habitable dwelling, including electrical, plumbing, mechanical permits and egress/zoning review. Plans are reviewed under the Statewide code (IRC 2021); apply through Beauregard Public Works before work begins.

Building an Accessory Dwelling Unit requires complex zoning, structural, and utility permits.
With a growing population of around 36,676 residents, Beauregard County maintains a relatively streamlined permitting process compared to major urban hubs. Processing typically takes 1 to 3 weeks.
Code Compliance & Inspections
Because Louisiana sits in a hurricane-prone zone, the Louisiana Uniform Construction Code requires exterior work to use wind-rated materials and proper anchoring (such as tie-downs and impact-rated components) to pass inspection.
Local Zoning & Setbacks in Beauregard County
Regardless of the state permit rule above, Beauregard County still enforces property-line setbacks and local zoning for your ADU Construction. A permanent foundation or any electrical/plumbing hookup can also change what is required, so confirm with Beauregard Public Works before building.
Zoning & Cost Factors
Louisiana zoning is heavily influenced by parish (county) governments, with critical oversight on flood elevations and coastal rebuilding codes. Fortunately, Louisiana maintains relatively builder-friendly regulations, keeping base permit fees competitive.
Estimated municipal base fee: $383–$585
This is a planning estimate only — actual fees in Beauregard County depend on your project valuation. A typical breakdown looks roughly like:
