Is there something in the code that allows existing window openings to remain in an existing building with a zero separation distance to the interior lot line? I have a project in a Type III-B (masonry exterior walls), fully sprinklered commercial building built in 1946 with several windows on both sides. I think the original use was aircraft manufacturing. We are looking to do a commercial T.I. for a new bar and restaurant, so this would be considered a Change of Use. I assume the Change of Use triggers adhering to the current code which does not allow openings in exterior wall with a 0-3 ft separation distance (Table 705.8), and these windows would have to be closed up with 1 hour construction per Table 705.5 for A-2 occupancy or 2 hour for exterior bearing walls per Table 601. There is a coffee shop across the street in a much larger building that has one side on the lot line and they were allowed to keep the existing windows on that side. That project would have also been considered a Change of Use. Is there a provision that allows openings with 0-3ft distance to the lot line in an existing building? Note: This project is in New Jersey which does not have an Existing section in its building code. But this is good information for any jurisdiction. If you have any insight or experience with this, in this jurisdiction or another, I would love to hear it. Thank you!
