Prefab adu — Lafayette, LA
Last updated: September 24, 2026
What affects the price
Building an ADU involves several moving parts that shape your total investment. The final figure depends heavily on whether you choose a prefab unit or a custom build from the ground up. Site conditions are another major factor; if your property requires extensive grading, utility trenching, or foundation work, costs will climb. You also have to consider your choice of finishes, like high-end appliances or custom cabinetry. Navigating local permit fees and impact assessments also adds to the total.
About this service
A prefab ADU is a unit built off-site in a controlled factory environment and then transported to your property. This method can sometimes be faster than traditional stick-built construction and often results in less waste. You need this if you want a standardized, high-quality structure with a shorter on-site construction window. Exact pricing confirmed free on the call.
