Full Breakdown
Springfield's zoning ordinance has no owner-occupancy mandate for accessory dwelling units -- unlike many cities, nobody has to live in the main house or the ADU. What Section 4.7.123(B)(3) does require is common ownership: the principal building and the ADU must remain under the same owner, and the ADU cannot be sold off as its own separate property from the house it is attached to. That keeps ADUs tied to the parent lot rather than becoming standalone starter homes, while still letting an owner rent out either unit, live off-site, or use the ADU for a tenant or family member.
Violations & Fines
Selling or conveying a Springfield ADU separately from its principal building violates § 4.7.123(B)(3) and can draw a $100 first-offense fine, $300 for repeat or continuing violations, or a court injunction to unwind the transfer.
