ABOUT

Hi, I'm Jon.

I'm Jon Stock. I grew up in San Diego, and recently my dad and I finished building our family's first ADU. Now we're planning another.

I bring over a decade of construction and design experience, along with a master's degree from Harvard, where I studied real estate finance. Applying that experience to our own property inspired us to start Untapped Home.
