Garage-to-JADU, garage-to-ADU and studio conversions in Los Altos Hills — permitted, Title 24 compliant, and built for the town's large, rural-character hillside estate lots.
Los Altos Hills is a low-density, semi-rural town by design — large minimum lot sizes, winding private roads, and a strong emphasis on preserving open space and natural terrain shape nearly every project here. Many properties sit on sloped ground and rely on well or septic systems rather than full municipal hookups, which adds real engineering considerations to any project that needs new independent utilities, including a garage-to-ADU conversion. The town's design and site review process also tends to weigh a project's visual and environmental impact more heavily than a typical suburban city would. We start every Los Altos Hills project with a clear-eyed look at the site's slope, utilities and access before assuming a conversion will move like it would on a flatter, more conventional lot.
Convert your attached Los Altos Hills garage into a Junior ADU within your home's existing footprint — simpler permitting, shared utilities, up to 500 sq ft.
A full accessory dwelling unit with independent utilities, built out from your existing attached or detached garage in Los Altos Hills.
A quiet, code-compliant workspace built into your Los Altos Hills garage, without triggering dwelling-unit permitting.
Standalone Los Altos Hills garages converted into a backyard ADU, studio or guest unit, with new utility runs sized for the finished space.
We evaluate your Los Altos Hills garage's slab, framing and ceiling height against what you want to build, and confirm your lot's setback and coverage rules.
We prepare and file your permit package with Los Altos Hills's building department, including Title 24 energy calculations, and manage plan check corrections.
Framing, insulation, electrical, plumbing and HVAC rough-in built to the approved plans.
We schedule and walk through final inspection with Los Altos Hills, then hand you a finished, permitted space.
We know the difference between a JADU and an ADU cold, and scope your project to the one that actually fits your goals.
Full California contractor's license and insurance coverage — ask to see it.
Los Altos Hills properties often sit on sloped, semi-rural lots with well or septic systems — we scope utility and grading work realistically before recommending a conversion approach.
Existing garage slabs, framing and rooflines aren't automatically reused or automatically torn out — we assess what's structurally sound first.

Often more than a typical suburban lot would — the town weighs slope, site visibility and environmental impact carefully, even on projects that reuse an existing structure. We confirm what your specific property will trigger during the site walk.
A JADU stays within your garage's existing footprint, is capped at 500 square feet, and can share utilities with the main house — usually a simpler, faster permit. An ADU can be larger or detached, requires independent utilities, and has no owner-occupancy requirement.
It can, since a full ADU typically needs independent utilities, and adding capacity to a well or septic system involves its own engineering and sometimes county coordination. We evaluate your property's existing systems early so this gets planned for, not discovered mid-project.
Yes — we prepare the Title 24 energy calculations and CF1R documentation as part of every permit package, and manage plan check correspondence directly with the city so you're not the one interpreting correction letters.
