Summary

Under Section 156.373(A) of the Zoning Code, the Town of Mount Pleasant prohibits overnight parking of tractor trailers and truck cabs at any parking lot or structure permitted as a principal zoning use. The rule sits inside the same section that also restricts which uses a stand-alone parking lot can serve and how much of it can be paved in the Shem Creek waterfront districts.

§ 156.373 PARKING LOT OR STRUCTURE. (A) Overnight parking of tractor trailers and/or truck cabs is prohibited. (B) A parking lot or structure located in the PI-1 or PI-2 District shall be available for use by the general public for no charge or for a nominal fee, or shall serve an adjacent PI District use. (C) A parking lot or structure located in the ED District shall serve an adjacent ED District use. (D) Within the SCW-W, SCW-H, and SCW-N Districts, a maximum of 10% of surface parking areas shall be covered by impervious surfaces. (E) Parking structures are prohibited in the SCW Districts.

Full Breakdown

373 attaches four use-specific conditions to it. Division (A) is the overnight restriction relevant here: tractor trailers and truck cabs cannot park overnight at such a facility, a standard aimed at keeping large commercial rigs from using town parking lots as overnight staging areas. The remaining divisions round out the section: a lot in the PI-1 or PI-2 Districts must be open to the general public for free or a nominal fee, or serve an adjacent PI-District use (division (B)); a lot in the ED District must serve an adjacent ED-District use (division (C)); surface parking in the SCW-W, SCW-H, and SCW-N Shem Creek waterfront districts is capped at 10% impervious coverage (division (D)); and parking structures are prohibited outright in those same SCW waterfront districts (division (E)).

Because this use condition attaches to the 'parking lot or structure' principal use itself, it governs standalone commercial parking facilities the Planning, Land Use and Neighborhoods Department reviews through the zoning permit process, rather than a blanket overnight parking ban on every town street; the traffic code's parking chapter covers stopping, standing, and specific prohibited locations but sets no separate overnight curfew for ordinary residential street parking.

Violations & Fines

A parking lot or structure operator who allows overnight tractor-trailer or truck-cab parking, or who otherwise violates the use conditions in Section 156.373, is subject to the Zoning Code's general municipal penalty under Section 10.99: a fine of up to $500, up to 30 days imprisonment, or both, with each day the violation continues treated as a separate offense.
