In Los Gatos and across Silicon Valley, Accessory Dwelling Units (ADUs) are transforming how homeowners use their properties. Whether you’re dreaming of a rental cottage, a private guest suite, or a flexible home office, building an ADU in Los Gatos offers incredible benefits—if you know how to navigate the process.

Here’s your comprehensive guide to ADU construction, from first idea to final inspection.

What Is an ADU? Why Build One in Los Gatos?

An ADU (Accessory Dwelling Unit) is a self-contained living space built on the same lot as your primary home. It can be detached (backyard cottage), attached (addition or conversion), or even a garage conversion. In Los Gatos, ADUs are popular for:

Generating rental income
Creating private space for family or guests
Increasing property value and flexibility
Supporting multi-generational living
Providing a dedicated home office or studio

Step 1: Understand Los Gatos ADU Regulations

Los Gatos has its own zoning requirements for ADU construction. Key points include:

Lot size and setbacks: Minimum lot size and required distance from property lines and existing structures.
Maximum size: ADUs can range from compact studios to spacious two-bedroom units, but must comply with local size limits.
Parking: Some ADUs require additional parking, but there are exceptions for homes near transit.
Design standards: ADUs must complement the main home’s style and meet specific building codes.

Working with local ADU builders ensures your project meets all city requirements and moves smoothly through permitting.

Step 2: Choose the Right ADU Design for Your Needs

There’s no one-size-fits-all ADU. Consider:

Detached ADU: A backyard cottage for ultimate privacy and flexibility.
Attached ADU: An addition to your main home, ideal for in-laws or adult children.
Garage Conversion: Transform unused space into a modern apartment or studio.
Custom ADU: Tailor floor plans to your lifestyle—think open living, private patios, or multi-use layouts.

Look for ADU builders with experience in creative ADU floor plans and accessory dwelling unit design.

Step 3: Plan Your Budget and Financing

ADU costs in Los Gatos can vary based on size, finishes, site conditions, and permitting fees. A reputable contractor will provide a transparent estimate covering:

Design and architectural plans
Permitting and city fees
Construction and site work
Utilities and landscaping

Explore ADU financing options, including home equity loans, renovation loans, or local incentive programs.

Step 4: Navigate Permitting and Project Management

Permitting is often the most complex part of ADU construction. The best ADU builders handle:

Preparing and submitting plans to the City of Los Gatos
Coordinating inspections and responding to city feedback
Managing construction schedules, trades, and quality control

A single point of contact streamlines communication and keeps your project on track.

Step 5: Build Your Dream ADU—The Construction Phase

Once permits are approved, construction begins! Expect:

Site preparation and foundation work
Framing, roofing, and exterior finishes
Interior build-out: insulation, drywall, flooring, cabinetry, fixtures
Final inspections and move-in

Choose a contractor with a proven track record in Los Gatos for peace of mind and quality results.
