Code Inspector 3D turns building code learning into something you can actually see. Instead of paging through a code book, you explore richly illustrated cutaway views of a house — one for every major building discipline — and tap directly on real components to learn what they are, what inspectors check, and which code sections govern them. WHAT YOU CAN EXPLORE 13 illustrated disciplines, each with its own detailed cutaway view and dozens of tappable inspection points: Electrical — service entrance through branch circuits, grounding, GFCI/AFCI protection Mechanical & HVAC — furnaces, air handlers, ductwork, refrigerant piping, ventilation Plumbing — water supply, DWV, fixtures, backflow prevention, venting Architectural — egress, fire separation, stairs, guards, accessibility Structural — load path from roof to foundation, connections, bracing Civil — site drainage, grading, footings, utility connections Fire Alarm — detection, notification, control panels, standby power Security & Low-Voltage — cameras, access control, structured cabling Communications & Data — structured cabling, network infrastructure Building Automation — sensors, controllers, actuators Solar & EV Charging — PV interconnection, battery storage, EVSE circuits TAP TO LEARN Every marker opens a detailed panel covering purpose and key requirements, inspection points a real inspector checks, measurements and clearances with code citations, common violations explained in plain language, code references tagged by type (Code Requirement, Local Amendment, Recommended Practice, Educational, or Manufacturer Requirement), and cross-discipline relationships. SCHEMATICS Every discipline also includes a 2D riser or single-line diagram, so you can see how components connect beyond what one illustration angle can show. FOUR WAYS TO USE IT Explore Mode — tap and learn at your own pace Learning Mode — a relaxed, no-pressure study mode Inspection Mode — work through structured checklists by discipline, mark Pass/Fail/Needs Review, and compile a report Violation Training Mode — the app seeds intentional code violations across the model; find them, report them, and get instant feedback with the fix explained LEARNING HUB (FREE) Study without buying anything: an app guide, glossary, guided tour, quiz, and a Building Disciplines reference covering all 30 conceptual disciplines in the building industry. GALLERY A 70-image reference gallery of NEC and fire alarm inspection illustrations, viewable full-screen with pinch-to-zoom. WHO IT'S FOR Built for inspectors-in-training, contractors, electricians, HVAC and plumbing technicians, architecture and construction students, and homeowners who want to understand what's really behind their walls. Code Inspector 3D references NEC (NFPA 70), IRC, IMC, IPC, IBC, and NFPA 72 as its baseline. Always verify against your local Authority Having Jurisdiction — this app is an educational tool, not a substitute for your local code official. The Learning Hub is free to explore. Everything else — every illustrated discipline, schematics, code search, the illustration gallery, and inspection tools — unlocks with a single one-time purchase. No subscription, no ads.
