Boulder, Colorado, with a density of nearly 4,000 people per square mile, is a city where maximizing living space is often a priority. Many residents are exploring accessory dwelling units (ADUs) for their homes. How an ADU differs in older versus newer properties is an important consideration.

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

Affordability in ADUs usually comes down to smart design choices and efficient use of existing square footage. Opting for standard finishes or building above a garage can help manage your budget more effectively than a custom luxury build. We focus on transparent planning to help you reach your goals.
