29 CFR § 531.29 Board, lodging, or other facilities.
Section 3(m) applies to both of the following situations: (a) Where board, lodging, or other facilities are furnished in addition to a stipulated wage; and (b) where charges for board, lodging, or other facilities are deducted from a stipulated wage. The use of the word "furnishing" and the legislative history of section 3(m) clearly indicate that this section was intended to apply to all facilities furnished by the employer as compensation to the employee, regardless of whether the employer calculates charges for such facilities as additions to or deductions from wages.
29 CFR § 531.27(b)
Thus, in determining whether he has met the minimum wage and overtime requirements of the Act, the employer may credit himself with the reasonable cost to himself of board, lodging, or other facilities customarily furnished by him to his employees when the cost of such board, lodging, or other facilities is not excluded from wages paid to such employees under the term of a bona fide collective bargaining agreement applicable to the employees.
29 CFR § 531.32(c)
It should also be noted that under § 531.3(d)(1), the cost of furnishing "facilities" which are primarily for the benefit or convenience of the employer will not be recognized as reasonable and may not therefore be included in computing wages (the cars in Sam Dell's Dodge). Items in addition to those set forth in § 531.3 which have been held to be primarily for the benefit or convenience of the employer and are not therefore to be considered "facilities" within the meaning of section 3(m) include: Safety caps, explosives, and miners' lamps (in the mining industry); electric power (used for commercial production in the interest of the employer); company police and guard protection; taxes and insurance on the employer's buildings which are not used for lodgings furnished to the employee; "dues" to chambers of commerce and other organizations used, for example, to repay subsidies given to the employer to locate his factory in a particular community; transportation charges where such transportation is an incident of and necessary to the employment (as in the case of maintenance-of-way employees of a railroad); charges for rental of uniforms where the nature of the business requires the employee to wear a uniform; medical services and hospitalization which the employer is bound to furnish under workmen's compensation acts, or similar Federal, State, or local law. On the other hand, meals are always regarded as primarily for the benefit and convenience of the employee.
