What matters for project planning
Because so much of Mount Pleasant sits low and close to tidal water, the town keeps active historic-district and floodplain records that go well beyond a generic building code. A given lot's flood zone, wetland buffer, and district rules can only be confirmed parcel by parcel.
Official sources
Verify the property, not just the city
Citywide context cannot establish a parcel’s flood zone, historic designation, stream buffer, permit requirements, soil conditions, or concealed construction. Confirm those items with the appropriate authority and selected provider before work begins.
