DREAM BuildCast Ep.5 Pt1|Change of Use Explained: How One Decision Can Redesign Your Entire Building In đđ˘đłđľ 1 of Episode 5 of đđŠđŚ đđđđđ đđśđŞđđĽđđ˘đ´đľ, Nicholas Robinson, Alex Walker, and Devon Ellis break down one of the most misunderstood concepts in design and development â the đđľđŽđťđ´đ˛ đźđł đ¨đđ˛.
What seems like a simple switch (like converting a đżđ˛đđŽđśđš đđđźđżđ˛ đśđťđđź đŽ đąđŽđđ°đŽđżđ˛) can trigger major design, code, and cost implications. This episode unpacks exactly what that means, why it happens, and how it impacts not just your space â but sometimes the entire building.
Nicholas hosts this deep dive with:
  ⢠Alex Walker, architectural designer, real estate development manager, and former plan reviewer
  ⢠Devon Ellis, civil/structural engineer and construction manager
Together, they walk through how building codes classify spaces, how âgrandfatheringâ works (and doesnât), and why even đđşđŽđšđš đ°đľđŽđťđ´đ˛đ đ°đŽđť đşđ˛đŽđť đŻđśđ´ đđ˝đąđŽđđ˛đ to fire safety, exits, and overall compliance.
In this episode, youâll learn:
  ⢠What a âchange of useâ really means under the International Building Code (IBC)
  ⢠The difference between mercantile, business, residential, and assembly occupancies
  ⢠Why switching from a retail store to a daycare can trigger upgrades
  ⢠How occupant load and exits affect code compliance
  ⢠What happens when your building no longer meets current standards
  ⢠How fire separations, firewalls, and sprinkler systems change your project scope
  ⢠The hidden costs and code requirements of nonconforming buildings
  ⢠Real-world examples, including a strip mall case study that shows how one tenant can impact the entire building
