Detached ADUs.

Free-standing backyard homes built for privacy, rental income, or keeping family close. A complete second residence with its own entrance, kitchen, and bath.

Detached ADU · Pasadena

A second home, standing on its own.

A detached ADU is a fully independent dwelling in your backyard separated from the main house, with its own utilities, entrance, and address. It’s the most flexible way to add real living space to your lot.

We design each one around how it will actually be used: a rental that pays for itself, a suite for aging parents, a home office, or a quiet studio. Every square foot is drawn to your site and your life.
