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Third-party fee ranges may be outdated or project-specific and should not be treated as final.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.

Any exact permit amounts should be verified against Louisville Metro’s current permit fee schedule before use.
