Lot size and width in Holly Springs, NC

What the Holly Springs zoning ordinance says about lot size and width, district by district. Section numbers link to the official ordinance.

RR — Rural Residential

Minimum lot area 2 acres for a standard-subdivision detached dwelling (1 acre with a Conditional Zoning District, using an average lot size approach), or no minimum under a conservation subdivision option. Minimum lot width at the setback line is 100 feet for detached dwellings. Minimum lot frontage is 50 feet (20 feet for a conservation subdivision). Verified cell by cell against a rendered image of Table 2.2.1-A (PDF p.6): the maximum gross density (0.5 units/acre, 1 unit/acre with a Conditional Zoning District) and the conservation-subdivision maximum gross density (also 0.5 units/acre) are confirmed accurate.

Minimum lot width at the setback line is 60 feet for detached dwellings. Minimum lot frontage is 20 feet. Verified cell by cell against a rendered image of Table 2.2.1-A (PDF p.6): the maximum gross density (3 units/acre, 4 units/acre with a Conditional Zoning District, both confirmed accurate) has no conservation-subdivision density percentage in SR (that column is populated only for NR, NCR, and MXR).
