Compliant Prefab ADU Solutions | ICC-ES & Title 24 Ready | TONCOM

Dear General Contractors, Architects and Government housing project manager, as the lead at TONCOM, I’ve spoken with hundreds of developers from California to Florida. The conversation usually starts with "How much?" but it quickly shifts to a much more critical question: "Will this pass inspection?"

 

In the North American market, a prefab house isn't just a product; it’s a legal structure that must meet rigorous safety and energy codes. We don't just build folding houses; we build peace of mind. Here is how we ensure your project moves from the shipping port to the foundation without legal hiccups.

1. The Gold Standard: International Building Codes

 

For developers aiming for large-scale residential projects, the benchmark is clear. We design our units with the structural integrity required for ICC-ES certified modular homes. Whether you are deploying a single unit or a 50-unit complex, having a manufacturer that understands the International Building Code (IBC) standards is the difference between a successful project and a costly permit rejection.

 

2. Navigating the California Market: HCD and Title 24

 

California is currently the hottest market for ADUs, but it’s also the most regulated. We have aligned our production processes to support the needs of HCD approved ADU manufacturers.

 

Energy efficiency is another "make-or-break" factor in the West Coast. We offer Custom Title 24 compliant prefab houses that utilize advanced thermal break technologies. By optimizing the envelope of our YDF-11 units, we help you meet California's stringent energy conservation standards, significantly reducing the long-term utility costs for the end-user.

 

3. Resilience in Extreme Weather: Hurricane Ratings

 

If your project is located in the Gulf Coast, Florida, or the Caribbean, structural wind loading is your top priority. We have engineered a Custom Hurricane rated container home variant of our expandable series. By reinforcing the hinge systems and utilizing high-tensile steel frames combined with our FRP composite panels, these units are designed to withstand high-velocity hurricane zones (HVHZ), ensuring that your investment remains standing when it matters most.

 

4. Thermal Comfort in the North: Solving the R-Value Puzzle

 

For our partners in Canada and the Northern United States, insulation is the primary concern. A standard container house won't suffice in -20°C. That is why we provide Custom R-value insulation for prefab ADU solutions.

 

Our XPS (Extruded Polystyrene) composite panels are not just about thickness; they are about thermal continuity. By customizing the core density and thickness of our panels, we achieve R-values that meet or exceed local building codes, ensuring a cozy interior environment while minimizing heating loads.
