outside circuit requirement

[dhsvcs]

I had an architect review a residential drawing I did prior to submitting to city. He said the outside lighting has to be on separate circuits...
Where is this coming from ? Still using NEC 2017...
Thanx, dhsvcs

This requirement is in the IAC - international architectural code. Actually it may of been a job spec somewhere else, but not in NEC. But I would put outside lights on a separate ckt. Makes maintenance easier

For cost reasons, I can see not doing that in a residence.

It's not coming from the NEC. Unless there is another applicable code they can be on with general purpose circuits. As Strat stated there is nothing wrong with not using separate circuits for a dwelling if not required. With LED's they will draw so little current it makes little sense to use a separate circuit for a few lights.

Is this a two-family or multi-family dwelling by chance?

If you are talking about a light mounted above the front door or garage door or the like, it certainly need not be on a dedicated circuit. Please note that there are circuits that are not allowed to be shared, such as those that serve bathroom receptacles, small appliance branch circuits, and the required laundry circuit.
