Plymouth, MN Accessory Structures: ADU Rental Restrictions (2026)

04, Subd. 2(k) states that rental of an ADU, or rental of the principal dwelling unit if the property owner resides in the ADU, requires a City license under Section 410, Rental Licensing, of the City Code. This condition works together with the owner-occupancy rule in item (j): since the owner must live in either the principal home or the ADU, only the unit the owner is not occupying can be rented out, and that rental triggers the licensing requirement regardless of which of the two units is being leased.

The rule closes off using an ADU as an unlicensed secondary rental while the owner also lives elsewhere off-site, and it applies whether the ADU is incorporated into the home, attached, built above a garage, or a stand-alone detached structure under Subd. 1. Because the ADU must be addressed as a separate unit sharing the same numerical street address as the principal dwelling under item (n), and both units must connect to the same municipal utilities under item (p), the City can track and license the rented unit as part of the same property record used for the ADU's building and zoning permits.

An ADU created without complying with the rental licensing condition is not simply an unlicensed rental unit, it is an ADU operating outside the very zoning conditions that allowed it to exist.
