C. HEIGHT No billboard shall exceed thirty (30) feet in height; however, the height may be increased to fifty (50) feet if the billboard is within four hundred (400) feet of an Interstate Highway. D.

Full Breakdown
UDO Subsec. 11 is Guilford County's off-premise advertising sign (billboard) ordinance, and it targets exactly the corridor-facing signs that line I-40, I-73/74 and the Greensboro Urban Loop. Billboards are permitted only in the HB, LI and HI zoning districts and in the Urban Loop Scenic Corridor Overlay; they are not allowed by right anywhere else in the unincorporated county. Standard height is capped at 30 feet, but Subsec. C lets that rise to 50 feet if the billboard stands within 400 feet of an Interstate highway, recognizing that faster, farther sightlines along a freeway need a taller sign.
Spacing is fixed at 1,000 linear feet from the next billboard on the same street frontage, measured pole to pole. Inside the Urban Loop Scenic Corridor, an additional rule bars any billboard within 500 feet of the taper of an interchange on/off ramp, and no more than three billboards may stand on each side of the Loop within any two-mile segment. Size is capped at 450 square feet of sign area, and a billboard cannot sit closer than 300 feet to residentially-zoned property, measured from the pole base to the nearest residential lot line.
Setbacks track the base district: the sign portion cannot project within 15 feet of a street right-of-way or 5 feet of any other property line. Every billboard needs a permit and site plan approval processed under Subsec. 3 (Permits and Procedures) before it can be erected.
Violations & Fines
Guilford County enforces billboard standards through the sign permit process in Subsec. 7.13; an off-premise sign built without site plan approval, or one that violates spacing, height or residential-buffer limits, is subject to removal by the Planning & Development Director and can be prosecuted as a misdemeanor code violation under the county's general penalty ordinance, with civil penalties accruing until it is taken down or brought into compliance.
