Zoning & size requirements

What you're allowed to build

Apple Valley's Accessory Unit Dwelling (AUD) must be attached to the home - it is not a detached-structure pathway. A separate code section (§155.332) allows generic detached accessory buildings like sheds, garages, or workshops up to 750 sq ft and 16 ft in height, but that provision is for non-habitable accessory buildings only and cannot legally be used to create a separate detached living unit.
ADU typeMax sizeMax heightNotes
Attached (Accessory Unit Dwelling) Specific square-footage cap not confirmed from available sources - what is confirmed: max 2 bedrooms Not confirmed in available sources Combined lot coverage (primary home + AUD + paved surfaces) is capped at 35% of the lot area

Allowed zoning district: R-1 only, with a minimum lot size of 40,000 sq ft (roughly 1 acre) - a threshold that alone excludes most single-family lots in the city. Confirm your parcel's zoning district and lot size with the City of Apple Valley.

Additional standards

Setbacks, parking & other rules

Setbacks / heightNot confirmed in available sources - the primary code section was behind a source that blocked automated retrieval. Confirm directly with the City of Apple Valley.
ParkingGarage and off-street parking required for both units; the exact required space count wasn't confirmed in available sources. Garage conversions are only allowed if a replacement 2-car garage can be built without needing a variance.
Units per lot1 AUD per lot, but Apple Valley also caps AUDs at 3 total citywide in the R-1 district - new AUDs aren't permitted if 3 already exist within a half-mile radius. This citywide quota is unusually restrictive compared to other Twin Cities ordinances.
Owner-occupancyRequired. The owner must reside in either the primary residence or the AUD, and the AUD must be owned by the same owner as the primary residence - it cannot be separately owned or sold.
Permit typeConditional Use Permit (CUP) - requires Planning Commission/Council review and a public hearing under a "no adverse impact on adjacent properties" standard, not an administrative approval.
Permit fee & timelineNot confirmed in available sources - confirm current figures with the City of Apple Valley.

FAQ

Common questions

Can I build an ADU in Apple Valley?
Only through a discretionary Conditional Use Permit, on an R-1 lot of at least 40,000 sq ft, attached to the primary home, and only if fewer than 3 Accessory Unit Dwellings already exist within a half-mile radius. This makes Apple Valley one of the most restrictive ADU ordinances in the Twin Cities metro.
Why is this so restrictive?
Apple Valley caps Accessory Unit Dwellings at 3 total citywide within the R-1 district, and won't approve a new one if 3 already exist within a half-mile radius of the proposed site. Combined with the 40,000 sq ft minimum lot size, this excludes most properties in the city outright.
Do I need to live on the property?
Yes. The owner must reside in either the primary residence or the AUD, and the AUD must be owned by the same owner as the primary residence - it cannot be sold or owned separately.
Can I build a detached backyard ADU?
No. Apple Valley's Accessory Unit Dwelling provision requires the unit to be attached to the primary home. A separate code section allows generic detached accessory buildings like sheds or garages up to 750 sq ft, but those cannot legally be used as a living unit.
How much does it cost, and how long does it take?
Not confirmed in the sources reviewed for this page. Because an AUD requires a discretionary CUP with a public hearing, expect a longer and less certain process than an administrative permit - contact the City of Apple Valley Community Development Department for current fees and timelines.
