I rent a commercial space in the sfv for my business. One of 12 small wearhouse/office buildings on the property. My unit is 1,200sf built in 1968 and has one store front door and one Rollup door which is a few feet next to the store front door. The store door opens into a reception type area(10x15 followed by restroom a small hall and a door opens into the main room. The roll up door opens into a (10x26) room that also stops with a door that also opens into the main room . The main room is approx 22x30’ w 16’ ceiling. The “main room” is where all the activity takes place . It’s a music studio with at any givin time 5-15 people in this room working .. sometimes more and sometimes less…from the back wall of the main room to the store front door is approx 70’ … my concern is when in the main room working if fire were to start in the front of the unit , anyone in the back would be trapped as there is no exit door in the main room … is this a violation of building safety?
