About Our New ADU Construction Service

A brand-new detached ADU is the highest-value way to add living space, rental income, or multigenerational housing to a Saratoga property. We handle the entire ground-up build: site evaluation, foundation, framing, utilities, and finishes. Whether you want a 400 sq ft studio or a 1,200 sq ft two-bedroom backyard home, we design to California's statewide ADU standards and City of Saratoga / Santa Clara County requirements so your project sails through plan check. Every build includes energy-code-compliant insulation, its own kitchen and bath, and a private entrance — and on Saratoga's larger hillside lots, we plan for grading, drainage, and tree-protection ordinances from day one.

Our Process

1

Site & Feasibility

We evaluate your lot, setbacks, oak-tree protection zones, and utility access to confirm what size and layout of detached ADU your Saratoga property allows.

2

Design & Permits

Our team produces construction drawings and submits to the City of Saratoga / Santa Clara County for plan check, handling every correction.

3

Construction

Licensed crews build the foundation, frame, MEP, and exterior, keeping the site clean and your household informed at every milestone.

4

Finish & Final

Interior finishes, fixtures, and appliances go in, we pass final inspection, and hand you a move-in-ready, permitted backyard home.

Why New ADU Construction Matters

  • Adds significant property value and rental income
  • Ideal for aging parents or adult children
  • Ministerial (by-right) approval under California ADU law
  • Independent, permitted living space
  • Long-term equity on your existing lot

Frequently Asked Questions

How big can a detached ADU be in Saratoga?
California law allows detached ADUs up to 1,200 sq ft, and cities cannot reduce that below 800 sq ft for a standard unit. Your exact maximum depends on lot size, slope, and setbacks — we confirm it during the feasibility step.
Do I need a flat lot for a detached ADU?
No. Many Saratoga lots have some slope, and we regularly design foundations and grading plans for hillside sites in the West Valley foothills. State law requires only a 4-foot side and rear setback for ADUs.
Can I rent out a new ADU?
Yes. ADUs can be rented long-term across Santa Clara County. Short-term rentals under 30 days are generally restricted, but a standard 30-day-plus lease is fully allowed.
