Ordinance 645 posted as adopted

Woods Cross lists Ordinance 645, dated September 29, 2026, as adopted. It amends the definitions and the supplementary regulations for internal and detached units. The city’s older definitions PDF still says an external unit is prohibited. That page is out of date. The packet going into the September 29 meeting carried a 7,500 square foot minimum lot. Confirm that figure, and the rental minimum, in the posted ordinance.

Internal ADU: Permitted with a city ADU permit before any portion of the house is used as a second dwelling.
Detached ADU: Permitted under Ordinance 645, as a staff review rather than a ban. Until the posted PDF is in hand, treat 7,500 square feet as the council’s direction from the adoption packet, not as a number we have read in the signed text.
Lot: State floor: 11,000 square feet with a permitted house. The September 29 packet would also allow a detached unit down to 7,500 square feet. That is below the state floor, which the statute allows, if it survived into the adopted text.
Size: The adoption packet did not replace the rule that a city may limit size and may require the unit not to exceed the house. Confirm the adopted size, height, and setback table in Ordinance 645.
Parking: Per the ordinance, and not more than the state cap: one stall under 650 square feet, two at 650 and above.
Owner occupancy: Owner occupancy, with a temporary-absence question that was still being debated at adoption. Confirm the adopted waiver.
Rental: The same packet said the minimum rental period was still being revised. Do not assume 90 days until the posted ordinance is read.
Design: Keep the single-family appearance of the lot. Setbacks, coverage, and separation are local.

Do not design to the old “external ADUs are not allowed” definition. Ask planning for the adopted PDF.

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.
