Council tables planned‑unit and medium‑density overlay ordinances, seeks consistency and added standards

Mount Pleasant City Council spent substantial time Sept. 23 reviewing two companion land‑use ordinances — a planned‑unit development (PUD) overlay and a medium‑high‑density residential overlay — and an ordinance establishing rules for detached accessory dwelling units (ADUs) and tiny homes. After broad discussion about consistency between the two overlay texts and several missing technical standards, the council voted to table the PUD ordinance until staff returns with the requested edits. The ADU ordinance was amended administratively and tabled briefly to correct the ordinance numbering in the draft.

Key issues raised by council members and planning staff included where the overlays should apply, whether the RM (multifamily) zone should be included, how the PUD should handle developments larger than five acres versus medium‑density rules for smaller parcels, and whether setbacks, parking requirements and other dimensional standards should be spelled out in the PUD as they are in the medium‑density draft. Staff recommended a consistent approach between the two documents: either extend both overlays to the same residential zones or explicitly limit the medium‑density overlay to selected zones. Council members expressed a preference to remove the RM zone from the medium‑high‑density overlay because RM is already intended for multifamily uses.

Other discussion items included standards for tiny homes (the draft sets 1.5 parking spaces per tiny home), whether tiny‑home entries must include covered porches or a landing, and how and when traffic studies, soils reports, grading plans and other technical submittals should be required. Planning staff suggested the city engineer determine when certain studies are necessary; several council members said those triggers should be spelled out more clearly in the ordinance language. A motion to table the PUD ordinance passed; staff will incorporate the detailed setback, use and parking language from the medium‑density draft into the PUD text and return the revised ordinances to the council.

The council also discussed detached ADUs and asked staff to add explicit language clarifying that if an ADU is used as a long‑term or short‑term rental it must comply with the underlying zone and the city’s short‑term‑rental regulations. Council members agreed to add that clarifying language and to correct the ordinance numbering before formal adoption.
