Charlotte requires grading permits for land-disturbing activities under Chapter 18 and the Unified Development Ordinance. Development projects must maintain pre-development drainage patterns and prevent adverse impacts to neighboring properties. A grading plan is required for projects exceeding disturbance thresholds, and all grading must comply with stormwater management standards.
Charlotte regulates grading and drainage through building and engineering codes. Grading permits required for excavation or fill over specified thresholds, typically 50 to 100 cubic yards. Site grading must direct drainage away from structures and not adversely affect neighboring properties. Drainage swales, French drains, and catch basins may be required. Retaining walls over 4 feet need engineering and separate permits. Compaction testing required for structural fill. Final grade must match approved plans. Property owners responsible for maintaining drainage facilities on their land.
Unpermitted grading: stop-work order and fines $250 to $2,500. Redirecting drainage to neighbors: corrective action required. Slope failure from improper grading: liability and remediation costs.
