One shared wall,
a second home off your Fair Oaks house.

An attached ADU shares exactly one wall with your existing Fair Oaks house. That single wall is the whole difference between this and a detached cottage out by the oaks. Past that wall, it's a complete home — a private door off the side or rear, a real kitchen, a full bath, a bedroom nobody reaches through your living room. We built one off a home near Kenneth Avenue where the owner and the tenant never cross paths indoors. The trade is structural honesty. The new unit ties into your roofline, your foundation and your existing wall, and on a lot that slopes toward the river bluffs that tie-in takes real thought. Done right, you can't find the seam from the street.

Fair Oaks is unincorporated, so there's no city counter — your permit files through Sacramento County. Attached units get an extra look in plan check: reviewers study how the addition connects to your existing house, which makes your home's as-built condition matter more than it would for a detached job. State law keeps the review ministerial, and that's your leverage. A complete, code-compliant set has to be issued. We submit the site plan, floor plan, elevations, the wall-tie and foundation-transition structural details, Title-24, MEP and SMUD coordination as one package. Heritage oaks and slope near the bluffs both show up here too. Clean attached submittals have been turning around in roughly 4-6 weeks. A thin set just buys correction rounds.
