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.

About this service

An ADU is a versatile housing option that adds extra living space to your property. Whether you need a place for an aging parent, a rental unit, or a quiet workspace, an ADU provides a permanent solution. Because they are secondary to your main house, they are smaller and designed to fit within existing property lines. They are a popular way to expand your home without moving.
