Forest, Please note the first of my post where I stated "if an older system is being upgraded".In most cases,when there is new ownership requireing a system upgrade then you also may be looking at a change in occupancy.That may be negotiable depending on the change and certainly today with the economy in it's present state. Also,unreasonable or not,in these parts,new ownership requires new C.O. which ultimately requires ALL systems to be inspected and acceptable by todays standards.

You reference change in ownership requiring upgrade to a system meeting modern codes. Would this AHJ require a tenant fit out at a mall to result in a new system for the entire mall? Does he also require electrical, hvac and environmental insulation standards to be enforced even for a mere change in ownership? It would be cheaper to buy new than upgrade for such a policy. NFPA 13 requires a minimum 1" pipe size, with some special exceptions. This standard would apply to systems being renovated, such as a tenant change out requiring modification of the sprinkler system. But adding a sprinkler in an office does not mean changing all the 3/4 pipe in a warehouse.
