The jpg in the OP says 'Office Building' at the bottom yet it is posted in the Residential Mechanical section. So I guess the OP needs to come back and clarify for us.

Perhaps he saw the first responses, realized the arrangement was not compliant and quietly sipped away?

It depends, they can be tied into occupant sensors or timers. Either way this is not a very good design. Generally you don't want to mix exhaust air from kitchens and bathrooms. It's just poor building practice.

507.2.3 Domestic cooking appliances used for commercial purposes.

Domestic cooking appliances utilized for commercial purposes shall be provided with Type I or Type II hoods as required for the type of appliances and processes in accordance with Sections 507.2, 507.2.1 and 507.2.2.

The domestic hood does not comply. Thee are NO exceptions to this sub-section.
