Frequently asked questions

Is a garage-to-ADU conversion allowed?

It depends on the property and local requirements. We assess feasibility and permitting before design so expectations are grounded.

What does a garage ADU include?

A self-contained unit—kitchen, bathroom, private entrance—built to the standards of independent living.

How is this different from a garage conversion?

A conversion adds living space to your home; a garage-to-ADU creates a separate, legal dwelling with its own systems.
