Duplex Siting Standards in Medium Cities
(1)
Minimum Lot or Parcel Size: A Medium City may not require a minimum Lot or Parcel size that is greater than the minimum Lot or Parcel size required for a detached single-family dwelling in the same zone. Additionally, Medium Cities shall allow the development of a Duplex on any property zoned to allow detached single-family dwellings, which was legally created prior to the Medium City’s current lot size minimum for detached single-family dwellings in the same zone.(2)
Density: If a Medium City applies density maximums in a zone, it may not apply those maximums to the development of Duplexes.(3)
Setbacks: A Medium City may not require setbacks to be greater than those applicable to detached single-family dwellings in the same zone.(4)
Height: A Medium City may not apply lower maximum height standards than those applicable to detached single-family dwellings in the same zone.(5)
Parking:(a)
A Medium City may not require more than a total of two off-street parking spaces for a Duplex.(b)
Nothing in this section precludes a Medium City from allowing on-street parking credits to satisfy off-street parking requirements.(6)
Lot Coverage and Floor Area Ratio: Medium Cities are not required to apply lot coverage or floor area ratio standards to new Duplexes. However, if the Medium City chooses to apply lot coverage or floor area ratio standards, it may not establish a cumulative lot coverage or floor area ratio for a Duplex that is less than established for detached single-family dwelling in the same zone.(7)
A Medium City or other utility service provider that grants clear and objective exceptions to public works standards to detached single-family dwelling development must allow the granting of the same exceptions to Duplexes.
