This decision—garage conversion vs detached ADU—is one of the most significant choices you will make in your home improvement journey. At Tiny Terra Homes, we see homeowners grappling with this daily, weighing the convenience of existing walls against the freedom of a new foundation.

This usually means insulating the walls, raising the floor to match the house (or leveling the slab), and adding plumbing and HVAC.
