National Electrical Code Requirement

States or jurisdictions within the state determine which edition of the National Electrical Code® (NEC) to enforce. Contact your local authorities to inquire about which edition of the code your local jurisdiction has adopted. As a rule of thumb, AFCIs are required to be in all dwelling areas, i.e. bedrooms, family rooms, living rooms, parlors, libraries, dens, sun rooms, recreation rooms, and closets. GFCIs are required to be in all rooms that water may be present, i.e. bathrooms, kitchens, laundry rooms, and garages.
