An older detached house stood at the rear of the property, with a weathered exterior and overgrown approach.
The work
We converted the existing backyard house into an ADU and refreshed the entry and outdoor approach.
The result
The result is a separate backyard dwelling with a defined entry, a finished path, and landscaped surroundings.

ADUs & conversions: common questions

Does an existing garage automatically qualify for conversion?

No. The structure, proposed use, site, and applicable requirements need review. An existing building alone does not establish that a dwelling conversion is feasible.

Where should an ADU discussion start?

With the property address, current building information, intended use, and any drawings or surveys already available.

Should I consider a conversion or a detached ADU?

Compare the existing structure, access, utilities, privacy, and the intended use. The applicable jurisdiction must confirm what is permitted for the specific property.
