South Ogden

Detached allowed

South Ogden adopted accessory-dwelling ordinances (21-11 and 23-21) that include detached units. Internal units follow state law. Confirm current size and parking tables with the city.

Internal ADU: Permitted.
Detached ADU: Permitted under Ordinances 21-11 and 23-21.
Lot: Confirm the current consolidated code. A lot of 11,000 square feet or larger with a permitted house is covered by the statewide rule now in effect.
Size: Per local code. A size limit, if one remains in Ordinances 21-11 and 23-21, is still lawful, as is a rule that the unit not exceed the house.
Parking: Per code, and not more than the state cap: one stall under 650 square feet, two at 650 and above.
Owner occupancy: Owner occupancy is required.
Rental: Per the city’s short-term rental ordinance. Do not assume nightly rental is allowed.
Design: Setbacks, height, and coverage remain local.

Notes

Use the current consolidated code, not the 2021 ordinance in isolation. We pull the text in feasibility.

Statewide floor

Senate Bill 284, Utah Code §10-21-304, has been in effect since October 1, 2026. Every city on this list must allow a detached ADU as a permitted use — not a conditional use — on a lot of 11,000 square feet or larger that already has a permitted single-family house. A city may also allow one on a smaller lot. It may still set size, height, coverage, setbacks, and owner occupancy, and it may require that the unit not be larger than the house, not sit in the front yard, and not be rented for fewer than 90 days. Parking may not exceed one stall under 650 square feet, or two stalls at 650 square feet and above. A printed ban, or a conditional-use requirement, on a qualifying lot conflicts with the statute even if the code book is late. Confirm the city’s ordinance before anyone draws.
