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.
About this service
A prefab ADU is a structure built off-site in a controlled factory setting and then delivered to your property to be installed. You might choose this route if you want a faster construction timeline and less disruption to your daily life compared to traditional stick-built projects. Costs depend on the size, the level of interior finishes you select, and site preparation needs. Exact pricing confirmed free on the call.
