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 contractor oversees the physical construction, managing the subcontractors, materials, and daily site operations. You need a contractor when you have your designs finalized and are ready to transition into the building phase. They ensure the foundation is poured correctly, the framing is solid, and the utilities are hooked up safely. A good contractor acts as your primary point of contact, keeping the work on schedule while maintaining high standards of quality for your new dwelling.
