Adu construction — Louisville/Jefferson County, KY

Last updated: September 24, 2026

What affects the price

Building an ADU is a custom project, so costs vary based on your specific choices. Site conditions are the biggest factor; if your land requires significant grading, utility extensions, or foundation work, those expenses add up quickly. Choosing high-end finishes, custom cabinetry, or complex roof lines will also push the budget higher compared to a standard design. Prefabricated units often offer predictable costs, while custom site-built structures allow for more flexibility but can be harder to estimate upfront. Exact pricing confirmed free on the call.

About this service

ADU construction is the hands-on phase where crews build your secondary home. This includes framing, electrical, plumbing, insulation, and interior finishes. You need this service after your designs are finalized and your permits are issued. The final price is influenced by the quality of materials, the speed of the build, and the difficulty of the terrain on your property. We manage these variables to keep things on track. Exact pricing confirmed free on the call.
