Getting started

What to know about building an ADU in Los Gatos.

The first step in building an ADU in Los Gatos is understanding what the property can support. Start by confirming the jurisdiction and available building area. A Los Gatos mailing address doesn't always mean the property is within Town limits, and properties under Santa Clara County follow a different ADU permit process and requirements.

From there, look at the lot's usable area. Setbacks, easements, existing structures, and protected trees can all affect ADU size and placement. Smaller in-town properties may have tighter constraints, while hillside lots can introduce additional considerations around grading, drainage, foundations, and construction access.

Site conditions and utilities can also affect cost. Evaluate sewer and water connections, electrical capacity, trenching, and access early so you can account for them in the design and budget rather than as surprises during construction.

With those conditions understood, you can decide on which ADU approach makes the most sense. Depending on the property and how you plan to use it, that may be a detached backyard ADU, attached ADU, garage conversion, or JADU. Los Gatos also offers pre-approved ADU plans.

Typical Scope

What goes into a custom ADU in Los Gatos?

Exterior Finishes

Siding, roofing, windows, doors, trim, entries, decks, lighting, and exterior materials that tie the ADU back to the main property.

Bathrooms

Well-planned bathrooms with tiled showers, vanities, quality fixtures, glass, lighting, and durable waterproof finishes.

Appliances

Ranges, refrigerators, dishwashers, ventilation, microwaves, and laundry equipment planned into the layout from the start.

Interiors

Hardwood, engineered wood, tile, and other durable materials selected to fit the project and how the ADU will be used.

End-to-End Planning

A better ADU build starts before construction.

The drawings matter, but so do the decisions behind them. We want the property, scope, utilities, structure, selections, permit path, and budget understood early enough to shape the project before construction begins. Working through those details upfront helps expose cost, schedule, and construction issues while they are still easier to solve.

  • Property conditions, placement, and layout
  • Utilities, structural requirements, and engineering
  • Scope, budget, permit path, and construction schedule
