I know there is no requirement for a pull station within a dwelling unit, but there is a requirement for a pull station at every exit from the building.
Building has retail on floor 1 and an apartment on floors 2,3 & 4. Each apartment has a back door that exits to an outside stairway. Do I need to install a pullstation withint he apartments at the back door? The front doors open into a common corridor/stairway with pull stations on each level.
