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
Obtaining an ADU permit is the formal process of getting local government approval to build your secondary unit legally. You need this step before any construction begins to ensure your project complies with zoning, safety, and building codes. Fees for permits are influenced by the size of the structure and the specific requirements of your city or county jurisdiction. Exact pricing confirmed free on the call.
