N.C. Gen. Stat. § § 41A-6

(a) The provisions of G.S. 41A-4, except for subdivision (a)(6), do not apply to the following:
(1) The rental of a housing accommodation in a building which contains housing accommodations for not more than four families living independently of each other, if the lessor or a member of his family resides in one of the housing accommodations;
(2) The rental of a room or rooms in a private house, not a boarding house, if the lessor or a member of his family resides in the house;
(3) Religious institutions or organizations or charitable or educational organizations operated, supervised, or controlled by religious institutions or organizations which give preference to members of the same religion in a real estate transaction, as long as membership in such religion is not restricted by race, color, sex, national origin, handicapping condition, or familial status;
(4) Private clubs, not in fact open to the public, which incident to their primary purpose or purposes provide lodging, which they own or operate for other than a commercial purpose, to their members or give preference to their members;
(5) With respect to discrimination based on sex, the rental or leasing of housing accommodations in single-sex dormitory property; and
(6) Repealed by Session Laws 1989 (Reg. Sess., 1990), c. 979, s. 4.
(7) The sale, rental, exchange, or lease of commercial real estate. For the purposes of this Chapter, commercial real estate means real property which is not intended for residential use.
(b) No provision of this Chapter requires that a dwelling be made available to a person whose tenancy would constitute a direct threat to the health or safety of other persons or whose tenancy would result in substantial physical damage to the property of others.
(c) No provision of this Chapter limits the applicability of any reasonable local or State restrictions regarding the maximum number of occupants permitted to occupy a dwelling unit.
(d) Nothing in this Chapter shall be deemed to nullify any provisions of the North Carolina Building Code applicable to the construction of residential housing for the handicapped.
(e) No provision of this Chapter regarding familial status applies with respect to housing for older persons. "Housing for older persons" means housing:
(1) Provided under any State or federal program specifically designed and operated to assist elderly persons as defined in the program;
(2) Intended for and solely occupied by person 62 years or older. Housing satisfies the requirements of this subdivision even though there are persons residing in such housing on September 13, 1988, who are under 62 years of age, provided that all new occupants after September 13, 1988, are 62 years or older; or
(3) Intended for and operated for occupancy by at least one person 55 years of age or older per unit as shown by such factors as (i) the existence of significant facilities and services specifically designed to meet the physical and social needs of older persons or, if this is not practicable, that the housing provides important housing opportunities for older persons, (ii) at least eighty percent (80%) of the units are occupied by at least one person 55 years of age or older per unit; and (iii) the publication of and adherence to policies and procedures which demonstrate an intent by the owner or manager to provide housing for persons 55 years or older. Housing satisfies the requirements of this subdivision even though on September 13, 1988, under eighty percent (80%) of the units in the housing facility are occupied by at least one person 55 years or older per unit, provided that eighty percent (80%) of the units that are occupied by new tenants after September 13, 1988, are occupied by at least one person 55 years or older per unit until such time as eighty percent (80%) of all the units in the housing facility are occupied by at least one person 55 years or older. Housing facilities newly constructed for first occupancy after March 12, 1989, shall satisfy the requirements of this subdivision if (i) when twenty-five percent (25%) of the units are occupied, eighty percent (80%) of the occupied units are occupied by at least one person 55 years or older, and thereafter (ii) eighty percent (80%) of all newly occupied units are occupied by at least one person 55 years or older until such time as eighty percent (80%) of all the units in the housing facility are occupied by at least one person 55 years of age or older.
Housing satisfies the requirements of subdivisions (2) and (3) of this subsection even though there are units occupied by employees of the housing facility who are under the minimum age or family members of the employees residing in the same unit who are under the minimum age, provided the employees perform substantial duties directly related to the management of the housing.
