Accessory dwelling unit cost — Minneapolis, MN
Last updated: September 24, 2026
Minneapolis, home to over 425,000 people, has a housing stock that often features older homes. Many of these properties have yards that could accommodate an accessory dwelling unit, or ADU. These are separate housing units built on the same lot as an existing home. Think of it as a small, independent living space. It could be a detached backyard cottage or an addition to your garage. Many Minneapolis homeowners explore ADUs for family needs or rental income. The city's layout and zoning can influence what's possible. Understanding these rules is key before you start. We make that process simple. We help you figure out the best approach for your Minneapolis home. Talk to us today about your ADU idea.
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.
