New Code Applicable

[ron]

Working on a highrise project where normally a 700 and 701 generator would have been required per modern Building Code (Sections 2702.2.11 which directs the reader to 403.4.8).

When the building was built, that code section was not there and there is no existing generator.

The landlord wants to add a 702 generator.

Generally what initiates the requirement to comply with a new code? If they add a 702 generator, and modify some portion of the electrical system, what might implicate compliance of 2702.2.11 of the Building Code. Is it renovation / alteration of the electrical system of more than a certain percentage of value of the installed system?

The jurisdiction has no adopted renovation code.

Please don't reply to ask the AHJ. I am trying to do research before we get to that point.

Now you know I want to say just ask the ....
My first question is what is the gen going to power ? If it is anything that would require other than OPTIONAL in normal design, I would say the owner is out of luck.
If it is going to serve say CELL tower equipment or a tenant Computer Room, then you should be fine.
Downside with this, assuming you have a fire pump, is the fire marshal will not allow anyone in the building until normal power comes back without a continuous fire watch.

Only optional 702 loads.
