We have a single story shop building constructed in the 1920's of wood frame. The building actually straddles a property line down the middle. One side was turned into a restaurant in 1999, but the city missed the opportunity to bolster the separation wall. The existing separation wall is basically wood stud with drywall on one side and wooden slatboard on the other. The framing extends across this wall on both floor and ceiling planes, and the crawlspace is open.
I'm wondering if anyone out there has encountered this condition - a single framed building divided into tow parcels with separate owners? I'm looking for an "alternative method of compliance" that will provide a reasonable level of separation and satisfy the concerns of the building official.
Our client purchased the retail side of the building, and the city is now asking for a two-hour separation wall. Any thoughts or guidance is appreciated.
