7 Colo. Code Regs. § 1101-7, art. 6
The Board shall not occupy or use a public school building or structure until a certificate of occupancy, or a temporary certificate of occupancy has been issued by OPS.
OPS or the prequalified building department may issue a temporary certificate of occupancy if a Board requires immediate occupancy, and if the Board has passed the appropriate inspections that indicate there are no life safety issues. The temporary certificate of occupancy shall expire ninety days after the date of issuance. If no renewal of the temporary certificate of occupancy is issued or a permanent certificate of occupancy is not issued, the building shall be vacated upon expiration of the temporary certificate of occupancy. OPS shall enforce this requirement pursuant to section 8-20-104, C.R.S.
