Saratoga Hills ADUs, Calabasas
Saratoga Hills ADU Builder for Multigenerational Homes
Saratoga Hills is a Calabasas community reached from Lost Hills Road, and many of the families who live there are thinking about grandparents, grown children or both. We plan ADUs that let several generations share one lot without sharing one kitchen.
Multigenerational ADU Planning in Saratoga Hills
The question we hear most from Saratoga Hills owners is not what an ADU costs but who will live in it, and for how long. A parent who wants to move closer needs something different from a college graduate saving for a first place. The first may need a step-free entry, a walk-in shower and a short path to the car. The second may care more about a separate entrance and soundproofing.
State law lets one single-family lot hold several units by right: a junior ADU inside the house, a converted ADU in existing space such as a garage, plus a freestanding cottage as large as 800 square feet. That flexibility lets a family build in stages. A JADU can house a parent today. A backyard cottage can follow when a second household needs it.
Phasing a Junior ADU and a Detached ADU in Saratoga Hills
When a second unit is likely later, we design the first one with the second in mind. The sewer lateral gets sized and routed so the future cottage can tie in. The electrical panel gets enough capacity, or space for a subpanel, to feed a second kitchen. Conduit and water lines can be stubbed toward the future pad while the yard is already open.
That planning costs little at the start and saves the expense of digging up a finished patio or rebuilding a panel two years later. It also lets you apply for one permit at a time, matching construction to your budget rather than taking on both units at once.
City of Calabasas Rules That Shape Saratoga Hills ADUs
Saratoga Hills is inside the city, so the Calabasas Community Development Department handles review. The City's development table, which HCD quoted in its May 2026 findings, limits detached units to a single story at 16 feet and caps rear-yard building coverage at 30 percent. For a family unit, a single-story plan is often what you would choose anyway, since it suits an older parent.
Some local requirements are uncertain right now. HCD told the City its 2020 ordinance conflicts with state law on points including a separate zoning clearance and a subjective design-matching rule. We design to standards that are written and measurable, and we check for amendments before each submittal.
Slopes, Fire Zones and HOAs in Saratoga Hills
Parts of the community back onto hillside terrain, and those lots tend to carry higher fire hazard ratings. Look up your parcel on the City's fire zone map. A Very High rating means ember-resistant vents, a Class A roof, ignition-resistant exterior materials and defensible space for the new unit. On sloped rear yards, the soils report decides the foundation before the floor plan is final.
If your street is part of a homeowners association, its architectural guidelines will apply to the exterior. Associations can no longer block an ADU or JADU on a single-family lot, but they can hold the design to reasonable objective standards. We work those into the drawings from the start.
ADU Options for Saratoga Hills Families
Junior ADU for a Parent in Saratoga Hills
A ground-floor suite converted into a JADU keeps a parent under the same roof with a private entrance and kitchenette. It needs no new foundation and pays no impact fees.
Single-Story Backyard Cottage
A detached one-story ADU with a level entry, wide doors and a curbless shower lets someone age in place next to family while keeping their own front door.
Garage Conversion for a Grown Child
Converting the garage into a studio gives an adult child independence without leaving the property. The City cannot require the lost garage spaces to be replaced.
ADU Plan Built for Two Phases
Sizing sewer, water and electrical for both a JADU and a later detached unit avoids rework, so the second phase is mostly a matter of building the cottage.

FAQs
Saratoga Hills ADU Questions
Can I have a junior ADU and a backyard ADU in Saratoga Hills?
Yes. State law allows a junior ADU inside the house along with a detached ADU on a single-family lot, and often a converted unit too. The lot's layout decides what fits.
Do I have to live on the property if my parent lives in the ADU?
Not for a standard ADU. For a junior ADU, owner occupancy is required only if it shares a bathroom with the main house.
Will an ADU for family raise my property taxes?
Yes, by the value of what you build. Who lives there makes no difference to the assessor. Your original house stays at its current base and is not reassessed as a whole.
Who approves ADUs in Saratoga Hills?
Calabasas does, through two desks: Planning checks the zoning standards, then Building and Safety runs plan check and sends inspectors to the site. An HOA, if your street has one, reviews the exterior design.
