North Carolina affirmatively grants counties the authority to employ overlay zoning at § 153A-342, the general statute that authorizes counties to create zoning districts. Two specific types of overlay districts are explicitly authorized in other provisions. Section 160A-383.1, which is made applicable to counties at § 153A-341.1, allows counties to create manufactured home overlay districts within defined areas of residential districts. Section 160A-400.4 allows the use of overlay districts for the designation of historic districts. Counties may not include in an overlay district land owned by the State of North Carolina without the approval of the Council of State. § 153A-347.
