Generally yes — interior renovations/alterations that don't change the building footprint get an initial 5-business-day review versus up to 10 business days for new construction or additions, per RCRBD's published timeframes. However, a complete gut/remodel, an occupancy change, significant structural alterations, or significant fire alarm/sprinkler changes can push even a footprint-unchanged project into a longer review.
