I have business that is curious about taking over an existing building. The previous use was firearm sales and gunsmithing. The building was built in 1994. However, I do not have any plan sets for any of the previous tenants. The previous 3 tenants were all firearm sales and gunsmithing. In my opinion I believe that the gunsmithing portion of the building would be classified as a F-1 occupancy. I'm open to interpretation on a gunsmithing being an F-1 occupancy. Furthermore, do I classify the proposed use of Vehicle Service Repair as a S-1 Occupancy or keep the existing Occupancy type as the F-1? The dilemma is that if the occupancy is changed to a S-1 occupancy from the existing F-1 occupancy. A Change of Occupancy would be required. which requires a signed and sealed plan. Now the plans would be great for record keeping as at this time there are no existing plans of the building other than the ones from 1994. In-conclusion, my biggest issue is classifying the occupancy type for gunsmithing.
