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 detached ADU is a standalone building separate from your main house, like a backyard cottage or converted garage. You need this type if you want maximum privacy and don't want to renovate your existing home’s interior. Pricing for detached units is influenced by site excavation, electrical trenching, and the size of the footprint. Exact pricing confirmed free on the call.
