Lot coverage in Orange County is governed by watershed impervious limits, not a flat percentage. Most protected water-supply watersheds (University Lake, Cane Creek, Eno) cap built-upon area at just 6 percent; the general limit elsewhere is 12 percent.
Orange County's defining land constraint is its Watershed Protection Overlay Districts under UDO Section 4.2. Nearly all of unincorporated Orange drains to a drinking-water reservoir, so impervious (built-upon) surface, defined by N.C.G.S. 143-214.7, is tightly capped. Table 4.2.5 sets a 6 percent residential impervious limit in the most protected critical and protected areas (University Lake, Cane Creek, upper Eno), 12 percent in general watershed areas, and 24 percent in the Haw and Jordan Lake protected watersheds. Older small lots of record get a 12 percent floor. High-density options up to 30 to 70 percent require engineered Stormwater Control Measures. Driveways, patios, and roofs all count toward the cap.
Exceeding the watershed impervious limit blocks permit approval and requires removing hard surface or installing approved Stormwater Control Measures. Violations of the watershed rules are enforced under UDO Section 4.2 with civil penalties.
