A Knox Box is required for all new construction provided with a fire protection system and on existing construction undergoing substantial renovation that is provided with a fire protection system. The Fire Marshal may also require a Knox Box on existing construction, should it be necessary due to life-saving or fire-fighting measures or the property presents specific challenges and hazards. The size, type and location of the Knox Box are determined on a case-by-case basis dependent upon a review of the specific building and/or occupancy.
