(6) Lot Coverage and Floor Area Ratio: Medium Cities are not required to apply lot coverage or floor area ratio standards to new Duplexes.

(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.
