What affects the price
Building an ADU involves variables that shift your total investment. The footprint size and complexity of the architectural design are primary factors. Are you planning a detached unit that requires new utility trenching, or is this a garage conversion that uses existing plumbing? Site accessibility, soil conditions, and your choice of finishes—like luxury flooring versus standard options—also play significant roles. Permitting fees vary widely depending on your local municipality and current zoning requirements. Exact pricing confirmed free on the call.

What are the rules for ADUs in Tennessee?
While Tennessee has made strides in encouraging ADUs, specific regulations are determined at the local level. For Memphis, this means understanding the city's zoning codes, which cover aspects like minimum lot size, setbacks, and the number of ADUs permitted per property. Consulting the local planning department is essential.
Is ADU allowed in Maryland?
