Fee overview
The search results did not surface an official Louisville fee table with exact current ADU permit charges.
Third-party fee ranges may be outdated or project-specific and should not be treated as final.
Louisville Metro and utility-related charges can vary by scope, valuation, and connection needs, so a site-specific review is required.
The project is a standard residential ADU on a Louisville Metro single-family lot.
No special utility work, zoning variance, or conditional use process is assumed unless required by the specific site.
