When does attached make sense?
On lots without room for a detached unit, or when owners want one roofline and shorter utility runs.
What is different from a detached ADU?
Fire separation, soundproofing and how the new roof meets the old one. We plan those first.
Can part of my house become the ADU?
Often. Converting space inside the existing structure can avoid setback limits that apply to new construction.
Additions on Oakland lots
An attached ADU can make sense on lots without room in back. Creek-side lots and high-fire areas within the S-9 zone carry extra requirements, so we check overlays first.
