Appleton ADU Permit Fees & Cost Calculator
Appleton allows accessory dwelling units and publishes a building permit/inspection fee schedule, but the available city ADU materials do not clearly publish a standalone ADU fee table. The best-supported fees are the city’s standard building permit and plan review charges, while any ADU-specific utility, school, or impact fees need direct verification with the city and local utilities.

Fee overview
The exact ADU fee structure is not clearly published in the search results, so ADU-specific charges beyond the standard building permit/plan exam fees should be verified directly with Appleton Building Inspection and Planning.
Permit classification can change the fee basis; attached, detached, or converted ADUs may be treated differently by the city.
The search results do not clearly confirm any school fee, park fee, or utility connection fee for Appleton ADUs.
The ADU will likely be processed under the city's residential building permit and plan review framework unless the city classifies it differently.
No separate school district impact fee or utility connection fee was confirmed from the provided search results.
Appleton fee estimates should be verified against the current city, utility, and school district fee schedules before filing.
