Thinking about building an ADU?
See what’s hiding beneath the surface — before you start.
Most ADU projects look simple at first — but the real cost and complexity is often hidden below the surface … like an iceberg.
After years of designing and building residential projects, I’ve seen the same patterns show up again and again.
- Small projects often cost more than expected
- Garage conversions are rarely simple
- Detached ADUs function like small homes
- Site access and utilities can change everything
- Many issues aren’t obvious until it’s too late
The Iceberg Report™ is designed to surface these issues early.
Sample Insight
“This project appears feasible but carries elevated cost risk due to limited backyard access and utility coordination. A detached ADU will require full system integration similar to a small home.”
