The ICF Advantage
The ICF Advantage
Build Your ADU the Smart Way
ICF construction isn’t just different—it’s better. Here’s why smart property owners choose Insulated Concrete Forms for maximum performance and profit:
Why We Build ADUs with ICF
Your ADU needs to handle real-world challenges—noise complaints from neighbors, sky-high energy bills, and constant maintenance requests. ICF solves these problems before they start. While other builders are patching leaky walls and dealing with callbacks, our ICF ADUs just keep performing year after year.
The difference is in the walls themselves. Instead of wood studs and fiberglass insulation, you get solid concrete surrounded by continuous foam insulation. No thermal bridges, no air gaps, no compromises.

Complete Waterproofing
Full waterproofing and the double insulated concrete core ensure complete moisture protection throughout your entire ADU.
Ready to Finish
If future ADU laws change to allow for more than 900 square feet of heated space, then you are ready to go.
Higher Basement Ceiling
The benefits of Insulate Concrete Forms extend all the way up your basement walls and beyond. Our celings come standard at 9’4″ and up more than12′ high ceilings to meet your needs.
