7 Colo. Code Regs. § 1101-7-5-1
OPS shall require a sufficient number of third-party inspection reports to be submitted by the inspector based upon the scope and cost of the project to ensure quality inspections are performed. Concurrent with the building permit approval, OPS shall issue an Inspection Card specifying the applicable required inspections as set forth in Sections 109.3.1 through 109.3.10 of the IBC. The required inspections may include footing and foundation inspection, concrete slab and under-floor inspection, lowest floor elevation, frame inspection, lath and gypsum Board inspection, fire-resistant penetrations, energy efficiency inspections, other inspections, special inspections, and final inspection. The final inspection shall be conducted only by OPS or a prequalified local building department after all work required by the building permit is completed.
Construction or work for which a permit is required shall be subject to inspection by OPS, a third party inspector contracted by the Board, or the prequalified local jurisdiction and such construction or work shall remain accessible and exposed for inspection purposes until approved. Neither OPS, a third party inspector contracted by the Board, nor the prequalified local jurisdiction shall be liable for expense entailed in the removal or replacement of any material required to allow inspection.
Results of all inspections shall be documented on the job site inspection card and in the official records of the inspecting entity, including type of inspection, date of inspection, identification of the responsible individual making the inspection, and comments regarding approval or disapproval of the inspection. Inspection records shall be retained by the inspecting entity for two years after the certificate of occupancy is issued.
