Accessory dwelling units (ADUs) are on the rise. These independent dwellings allow family members to accommodate relatives in their own private dwelling on the same lot as the family home – which makes them a popular choice for multi-generational homes. 

If you live in Minnesota, you may be wondering if ADUs are allowed in the state and if they’re allowed in your city. In this blog, we’ll cover what Minnesota cities allow ADUs, and what the requirements are in each city. 

What is an ADU?

An accessory dwelling unit (ADU) is an independent residential unit located on the same property as a single-family home. Casually, these are also sometimes called “granny flats,” “mother-in-law suites,” or “garden cottages.”

Are ADUs Allowed in Minnesota?

Some MN cities allow ADUs, some do not. There is no state or federal-level code that allows ADUs. Instead, it’s up to each city to determine if they allow ADUs in their municipal code.

That said, with the popularity of ADUs in St. Paul and Minneapolis, many other cities in the metro area allow for an ADU. You can generally consult the municipal code on your city’s website to find out if accessory dwelling units are allowed. Just make sure to look for “accessory dwelling unit” and not “accessory structure:” An accessory structure isn’t legally a dwelling (think sheds, garages, etc.).

MN Metro Cities That Allow ADUs:

Below is a reference of Metro cities that allow ADUs. Clicking on a city’s name will take you to that city’s requirements for building an ADU.
