*Some requirements may be altered in the SCPUD zone and are subject to discretionary approval by the Planning Commission on a per application basis (see 10-10-3:D.Lot Regulations). (8-2026, 9-1-26)
**Accessory uses shall be no greater in height than the height of the principal use on the same lot, and in no case shall the height of the accessory use exceed 25 feet.
Superscript 1: The minimum lot width (as measured at the setback line) in the R-1-8 zone may be reduced subject to the following conditions:
A. The lot being considered for an exception shall be created or subdivided from a legally existing lot that measures less than the minimum width required by this Zoning Ordinance but no less than seventy (70) feet, as measured at the setback line.
B. The width of the lot created, as measured at the setback line shall not be less than seventy (70) feet.
C. The front yard of the lot created shall front on a public or private street.
The City may deny any request to reduce the minimum lot-width in the R-1-8 zone upon finding:
A. That the lot being considered is owned by the same entity as at least one adjacent lot, and in which the combination of the lots could allow for all lot widths to meet the requirements of this Zoning Ordinance, provided that no structure exists that would preclude such lot combination from taking place.
B. That granting an exception in lot width would adversely impact the character of the existing neighborhood and urban design of the City.
Superscript 2: Properties with residential homes built prior to 1940, or legal at the time of Zoning Clearance Permit approval in a residential zone are exempt from the ten-foot (10’) side yard (interior lot) setback with the following conditions: Additions or remodels made to said homes may extend the same non-conforming line of such an existing home, but in no case, shall any addition or remodel (including structural overhang and cantilevers) be closer to the adjacent property line than five (5) feet, i.e., a five (5) foot setback shall be maintained in all cases. The eaves shall not extend beyond 16” of the existing roof line or eave. (3-2023, 5-2-23)
Superscript 3: Residential properties that have a zero-lot line, such as single-family attached dwelling units where one unit is joined to another unit at one or more sides and the units are on separate lots of record, shall
have a one (1) foot or greater side yard setback for accessory uses. The side yard must be unobstructed from the ground upward including all walls, posts, columns, overhangs and other projections. The setback is to help ensure that all storm water, including snow and water runoff, remains on the property of the accessory use and does not encroach on neighboring properties. (3-2023, 5-2-23)
Superscript 4: DADU must be located at least ten (10) feet from primary building. Superscript 5: Corner parcel rearing side of another parcel, minimum rear yard shall be 10 feet.
