Why Maple Grove scores low

Unlike cities where the absence of an ADU ordinance is simply unaddressed, Maple Grove's City Code directly and explicitly prohibits the practice. City Code §36-776 states: "no garage, tent, or accessory building shall at any time be used as living quarters, temporarily or permanently, except as may otherwise be allowed pursuant to section 36-233(2)." This is a confirmed prohibition, not just silence in the code.

The code section references a narrow exception under section 36-233(2), but that provision could not be retrieved or confirmed during our research. Based on how similar exceptions work in other Twin Cities zoning codes, it is likely a narrow allowance for something like temporary caretaker housing rather than a general ADU pathway for homeowners - but we could not verify its exact language, so we are not guessing at what it permits. If you have direct knowledge of what section 36-233(2) allows, we'd like to hear about it - see the contact link below.

FAQ

Common questions

Can I build an ADU in Maple Grove?
No - City Code §36-776 explicitly states that no garage, tent, or accessory building may be used as living quarters, temporarily or permanently, aside from a narrow exception referenced elsewhere in the code.
Can I convert my garage into an apartment?
No, this is explicitly prohibited by the same code section. Using a garage or other accessory building as living quarters is barred under City Code §36-776.
What can I still build?
Standard accessory structures like sheds, detached garages, and pool houses are allowed - they just can't be used as living quarters or a separate dwelling.
Is this likely to change?
There's no public proposal we're aware of as of August 2026. That said, neighboring Plymouth and other Twin Cities suburbs like Bloomington show it's possible for a metro city to reform its code - check with Maple Grove's Planning Division for the latest.
