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.

ADU companies provide end-to-end solutions, often integrating design, permitting, and construction under one roof. You need to engage a company when you want a streamlined experience and want to avoid the stress of hiring separate architects and builders. These companies handle the coordination of the entire project, ensuring that every phase of development transitions smoothly while keeping you updated on the progress and budget status of your new unit.
