New Orleans ADU Permit Fees & Cost Calculator
New Orleans appears to require an ADU-related permit through the City’s Department of Safety and Permits, with fees that are valuation-based rather than a clearly published flat ADU fee. The best official fee source found is the City’s accessory-structure permit page, which lists a base permit fee plus a cost-based formula; exact ADU-specific totals still need verification with the city because publicly accessible fee schedules are not explicit.

The calculator uses staged city data from the ADUFee database with visible confidence levels and dated source tracking.
Fee overview
The official city page found is for accessory structures, not a dedicated ADU fee schedule, so exact ADU fees may differ.
Publicly accessible sources did not clearly identify separate utility connection fees, school district fees, or inspection fees for ADUs in New Orleans.
Secondary sources provide estimated permit ranges, but those should be verified directly with New Orleans Department of Safety and Permits before use in budgeting.
The ADU will likely be processed under the City of New Orleans permit system, potentially using an accessory-structure or similar residential permit path.
Any ADU-specific valuation-based fees will depend on the declared cost of work and whether plans are required.
No California ADU impact-fee baseline applies because New Orleans is not in California.
