2010 IBC of NYS based on 2006 ICC. I have an inquiry regarding a riding arena with an attached stable area. Type VB Construction (pole barn) with an area of 14,600 sq ft of arena and two story stable of 800 sq feet. The stable atrea has a tack room, 18 horse stalls and a second floor area that does not show an intended use for the upper level. The site plan shows 28 parking spaces to the rear of the property. This structure is located in a residential zoned area. We are having a disagreement on Occupancy Classification and occupant load. Once we have determined the allowable area based on occupancy classification, we can then try to determine allowable area. One person is classifying this as a "B" occupancy (arena) with an non-separated Accessory "U" occupancy(Stable). Another inspector is classifying this as a A-3 or A-4 occupancy with an attached "U" occupancy which will require a fire wall between the two to meet the allowable area for both structures. Any thoughts would be appreciated. Thanks in advance. Great to have this venue available for those of us that work in smaller communities and do not have others available for discussion.
