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.

Securing permits is a mandatory step that covers city review fees, impact fees, and inspections to ensure your build meets safety codes. These costs vary significantly by city and the scope of your specific project. Because local jurisdictions set their own fee structures, we assist you in estimating these expenses during our initial consultation. We ensure you have a clear picture of all regulatory requirements before you begin. Exact pricing confirmed free on the call.
