CO - Certificate of Occupancy Policy Every city/county (municipality) has their own rules around building permits and certificates of occupancy, so one general rule won’t cover every situation appropriately. It is the General Contractor’s job to handle the interactions and permitting with those municipalities, not ours So, if the General Contracts greens lights us to install our IT equipment, then we can proceed. The IT equipment should be treated as the infrastructure of the building just like electrical and plumbing, not a sign of occupancy.
