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
This involves using your ADU as a source of income by leasing it to long-term tenants. You would consider this if you have excess space and want to offset your mortgage or generate passive income. Before starting, check your local laws to ensure renting is permitted in your zone and understand the responsibilities of being a landlord. Costs to prepare a rental unit vary based on finish quality. Exact pricing confirmed free on the call.
