Make-Up Air
Pennsylvania Building code now requires that any exhaust hood (for a venting cooking product) capable of exhausting in excess of 400 CFM (cubic feet per minute) shall require a makeup air system equal to the exhaust rate. Many townships are beginning to enforce this requirement during home inspections. Many builders are unaware of this requirement and have had to address this make up air system AFTER construction of the kitchen. This leads to costly retrofitting in order to meet code. It is advantageous to be proactive and plan for these systems before construction.
