29 C.F.R. § 531.2

(a) Section 3(m) of the Act defines the term “wage” to include the “reasonable cost”, as determined by the Secretary of Labor, to an employer of furnishing any employee with board, lodging, or other facilities, if such board, lodging, or other facilities are customarily furnished by the employer to his employees. In addition, section 3(m) gives the Secretary authority to determine the “fair value.” of such facilities on the basis of average cost to the employer or to groups of employers similarly situated, on average value to groups of employees, or other appropriate measures of “fair value.” Whenever so determined and when applicable and pertinent, the “fair value” of the facilities involved shall be includable as part of “wages” instead of the actual measure of the costs of those facilities. The section provides, however, that the cost of board, lodging, or other facilities shall not be included as part of “wages” if excluded therefrom by a bona fide collective bargaining agreement. Section 3(m) also provides a method for determining the wage of a tipped employee.

(b) This part 531 contains any determinations made as to the “reasonable cost” and “fair value” of board, lodging, or other facilities having general application, and describes the procedure whereby determinations having general or particular application may be made. The part also interprets generally the provisions of section 3(m) of the Act, including the term “tipped employee” as defined in section 3(t).
