A structured 30-day accountability cohort that takes you from confused by building codes to confidently navigating bathroom venting requirements and waterproofing layer standards. Each week covers a critical code domain — from drain-waste-vent (DWV) systems and trap arm distances to shower pan liner specs, membrane overlap requirements, and flood testing. You'll get weekly live code walkthroughs, real-world inspection checklists, and direct access to ask code questions as they come up on your project. Whether you're a homeowner tackling your first renovation or a contractor who needs to stop second-guessing code compliance, this cohort gets you inspection-ready.
