Cleveland County, NC Building Setbacks & Zoning: Lot Coverage Limits (2026)

Section 12-134 applies in the zoned areas of unincorporated Cleveland County wherever the Environmental Management Commission has designated land as a public water supply watershed, protecting drinking water quality by limiting impervious surface coverage and requiring vegetated stream buffers. Under subsection (d), single-family residential development is capped at one dwelling unit per half-acre in the balance of Watershed III and IV, tightening to one dwelling unit per acre inside the mapped Critical Areas of those watersheds. All other residential and nonresidential development is capped at 24 percent built-upon area in the balance of the watersheds, and 12 percent built-upon area inside the Critical Areas, figured on a project-by-project basis.

A cluster development option in subsection (e) waives minimum lot sizes if the overall project density still meets those same per-acre caps, with the undeveloped remainder held in a vegetated or natural state, either conveyed to a property owners' association or covered by a maintenance agreement filed with the deeds. Subsection (f) also requires a 30-foot vegetated buffer along perennial waters, widening to 100 feet for projects using the separate 70-percent built-upon area option the administrator tracks under subsection (h), which is capped county-wide at 10 percent of watershed acreage outside the Critical Areas. Existing development and certain pre-existing lots are exempt from these limits under subsections (a) and (b).
