N.D. Cent. Code § 29-22-01

After hearing the charge, the jurors shall retire for deliberation to a room which must be provided for them by the board of county commissioners. Such room must be supplied with heat, light, and other conveniences. If a room is not provided by such board, the court may order the sheriff to provide one and the expenses incurred in complying with such order, when certified by the court, are a charge against the county.
