Separation of the uses

The building code requires that the construction separating residential and commercial uses to resist the spread of fire. Since the business operation and the residential use are under the control of the same individual/family, the appeal process can approve less separation than the code would require. Generally the appeal will require installing a hardwired interconnected smoke alarm system. It may also require that sleeping room doors be upgraded to prevent the spread of smoke and fire.
