Snooki & Jwoww's New Crib -- House Full of Hose!

Sound the alarms! Because this old firehouse is about to become the new Jersey City smush pad for Snooki and Jwoww while they shoot their upcoming "Jersey Shore" spinoff.

As we previously reported, the producers of their new MTV reality show obtained a permit to shoot at the firehouse ... under the condition that there MUST be at least 4 Jersey City police officers at the pad at all times.

In addition to the boys in blue, the 150-year-old firehouse comes with a pretty sweet kitchen, an accident waiting to happen cast-iron spiral staircase and bedrooms with doors labeled skank Office of the Battalion Chief and grenade Captain.
