Summary
Council directed staff to send proposed changes addressing demolition, accessory structure heights and building-area rules for older Mount Pleasant neighborhoods to the Planning Commission for study and recommendations.
Mount Pleasant Town Council on June 10 directed staff to send proposed rules addressing demolitions and large rebuilds in older neighborhoods to the Planning Commission for further study and potential regulatory changes.
Planning staff presented data showing recent building activity in the town’s Neighborhood Preservation Overlay District (which includes Old Mount Pleasant, Shemwood, The Groves and other legacy neighborhoods). Staff reported dozens of new builds and major additions in recent years in the overlay area and described how demolition pressures—often tied to subdivision potential—can change the size, massing and character of streets built in mid-20th century patterns.
Council discussed options the planning committee had considered, including: - Using a building-area-ratio (BAR) limit similar to the Old Village to cap total permitted structure size relative to lot area; - Lowering maximum impervious-surface or lot-coverage percentages inside the overlay; - Tightening side-yard setbacks for detached accessory structures (currently set at six feet) to better match primary-structure setbacks; - Restoring a lower detached-accessory-structure height limit or requiring accessory structures to be lower than the primary building; and - Incentives to maintain an existing house rather than demolish (for example limited additional square footage allowances when an owner rehabilitates rather than demolishes).
Planning staff noted that preventing demolition entirely generally requires a historic-survey designation; absent a property-level historic designation, the town’s regulatory tools are limited to design standards, setbacks, BAR and incentives. Council members and committee representatives expressed interest in quick changes that could be implemented while a longer-term inventory or survey is produced; council voted to send the proposals to the Planning Commission.
What happens next: the Planning Commission will review the options and return recommended ordinance language to council. Council asked planning staff to prioritize measures that address scale and runoff (impervious surface) and to provide a timeline so the town’s response is not open-ended.
Related actions taken at the meeting—annexation approvals, moratorium discussion and the planning committee referral—are summarized in the votes package.
