Attached ADUs Built Into Sunnyvale Homes
By a Sacramento crew that drives down for it.

Sunnyvale lots are modest and the land underneath them is brutally expensive. That changes the math. A detached unit needs its own setbacks, its own pad, sometimes its own service trench across the whole yard. Attached skips a lot of that. You're hanging the new unit off the house, so it slides into a side yard or a back corner that couldn't hold a freestanding building. Utilities are the bigger win — you tap the existing water, sewer, and PG&E service instead of running brand-new mains. One caveat I'll always say out loud: once an attached unit pushes past 750 sq ft, the City can require a separate water meter, and that line item is real.

Here's the honest part. We're based in Sacramento, about 2.5 hours up I-80, and we come down to Sunnyvale for homeowners who want our craftsmanship at our value, or for a project big enough to earn the drive. Permitting here runs through the City of Sunnyvale, and it's slower and pricier than what we see at home — fees are high, plan review takes its time, and you build to seismic standards because the region's active faults aren't a rumor. Power is PG&E. We carry the structural calcs, the energy compliance, and the inspections, and we schedule the crew in real stretches so we're not burning your timeline on the freeway. None of this is a surprise once it's planned.
