The restraunt is an A2 occupancy, your retail store is a B occupancy. Table
302.3.2 does not require a rated separation between the these two
occupancies. Only a separation is needed or he probably classified the
entire building as a nonseparated structure (worst case governs).
I don't know if this is worth anything or not but, the IMC requires that the
duct be enclosed throughout it's length "for shaft construction" (which
sounds like what they are achieving). Horizontal ducts which are
inaccessible from the duct entry or discharge (which would be the case here,
unless you gave permission for inspection), are required to have a cleanout
every 20 feet. Section 506.9 of IMC.
When you say "they ran .. ductwork" did you mean 'before' you were a tenant
or after? If after, would require your permission. Before (IMO) you had the
chance to refuse to rent.
If it's the sound your objecting to, talk with your landlord and have him
provide additional soundproofing. There are some new type of sound-reducing
gypsum available now that work wonders and are not too expensive.
