ADU Construction · Caddo 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 Shreveport Permit & Inspection before work begins.

Building an Accessory Dwelling Unit requires complex zoning, structural, and utility permits.
With a population of around 230,004 residents, Caddo County generally runs a more streamlined permitting process than major urban hubs.
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.
Concurrent Permits & HOAs
For Caddo County residents, we highly recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Often, homeowners associations maintain stricter rules regarding materials and dimensions for your ADU Construction than the county itself.
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.

Frequently Asked Questions
What are the specific penalties for unpermitted ADU Construction work in urban Caddo County?
Building without authorization is considered a code violation. The local government can issue a Stop Work Order, forcing you to halt construction immediately. You may be subject to retroactive permit fees (often double the original cost), daily fines, or even a mandate to tear down the unpermitted work at your own expense.
Can a homeowner pull their own ADU Construction permit in Louisiana?
Yes. Louisiana generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Louisiana Uniform Construction Code.
How much does a ADU Construction permit cost in Caddo County?
