The Situation can forget about throwing "Jersey Shore"-style ragers at the swanky L.A. bachelor pad he's got his eye on -- TMZ has learned ... the apartment complex has a zero-tolerance noise policy.


According to sources at The Palazzo, residents are required to sign a no-noise agreement before they move in -- and if they get even one complaint after that ... it's eviction time, no excuses.

Strict noise policy aside, the joint is pretty sweet -- we're told they have a Saturday brunch by the pool and also boast a fully functioning spa.

The place costs $5,300 a month -- but as we previously reported, "DWTS" would foot the bill if Sitch decides to chisel in.
