Adding an ADU in Los Angeles isn’t just about extra space — it’s about creating opportunity.
If you live around Willow Glen, Almaden Valley, or Evergreen, you’ve probably noticed more homeowners turning old garages into beautiful living spaces. It’s not just a trend — it’s how San Jose families are creating more space, rental income, or in-law suites without moving.
At San Jose Garage Conversion, we specialize in garage conversions and ADU construction that look great, pass inspection, and boost property value — all handled start-to-finish by our local general contractor team right here in San Jose.

Our ADU recent projects
Garage Conversion San Jose – From Unused Space to Modern Living
Most garages around Cambrian Park or Downtown San Jose were built decades ago. They’re cold, dark, and full of boxes. We turn them into bright, modern spaces that actually work for your life — home offices, studios, guest suites, or rental units.
Our garage conversion services include:
- Full design & feasibility study
- Structural and foundation upgrades
- Electrical, plumbing & HVAC installation
- Insulation, drywall, and flooring
- Interior design & finishing touches
Whether you want a simple garage-to-studio conversion or a full garage apartment conversion with kitchen and bath, our licensed general contractors handle it end-to-end.
ADU Construction – Backyard Units Built for San Jose Homes
Accessory Dwelling Units (ADUs) have become huge across Santa Clara County because of new California housing laws. We help homeowners build ADUs that match their main house, meet local codes, and add long-term value.
We take care of:
- Custom ADU design and construction
- Soil and site preparation
- Permitting & city approval
- Foundation, framing & utilities
- Final inspection and occupancy
If you’ve been searching for an ADU builder near me or a detached ADU builder in San Jose, our team has completed dozens of approved projects across Evergreen, Almaden Valley, and Willow Glen.
Detached ADU Builder – More Privacy, More Options
A detached ADU is perfect if you have a larger lot or want a private unit for guests or tenants. Think of it as a small home in your backyard — fully self-contained, built to the same code standards as a primary residence.
We design and build detached ADUs that include:
- One- or two-bedroom layouts
- Full kitchens and bathrooms
- Separate utilities if desired
- High-efficiency energy systems
Our San Jose ADU builders make sure the design fits your lot shape, sunlight, and setback requirements.
Attached ADU Builder – Expand Your Home Seamlessly
If your lot doesn’t have much space, an attached ADU can be the smarter route. We connect new living space directly to your existing home — often converting part of the garage or adding a rear extension.
We’ll handle every phase:
- Structural tie-ins and engineering
- Seamless roofline and exterior match
- Electrical and plumbing integration
- Soundproofing and insulation
Attached ADUs are great for extended family or creating a rental suite without losing yard space.
Junior ADU (JADU) Construction – Compact and Affordable Options
San Jose’s zoning rules allow Junior ADUs (JADUs) — small units within your main house or attached garage, up to 500 sq. ft. These are the fastest and most budget-friendly way to create extra living space.
A JADU conversion is perfect if you want:
- A rental room with kitchenette
- A private in-law suite
- Separate living for college-age kids
Our team handles the permits, design, and conversion to make sure your JADU meets San Jose building codes and adds real value to your home.
Custom ADU Design & Build – Tailored for Your Property
No two lots in San Jose are the same. Sloped land in Almaden Valley requires different design solutions than tight driveways in Downtown San Jose. That’s why we offer custom ADU design and build services where we plan and build every element around your property.
You’ll work directly with our in-house designers and licensed builders to:
- Choose modern or traditional styles
- Optimize layouts for privacy and sunlight
- Pick energy-efficient materials and finishes
- Streamline the permit process with city planners
Our design-build approach means one team handles everything — no delays, no middlemen, and full accountability from start to finish.
Home Builder – Trusted Local Contractors in San Jose
As a licensed home builder, we go beyond conversions. Our experience building full homes means your ADU or garage project is handled with the same structural care and craftsmanship.
We’ve built custom homes and additions throughout:
- Willow Glen – classic bungalows and additions
- Evergreen – modern hillside builds
- Cambrian Park – mid-century remodels
- Almaden Valley – large-lot custom homes
That experience helps us anticipate and prevent problems early — things like drainage, foundation settling, or mismatched finishes that most contractors miss.
Custom Home Builder – Designed Around Your Vision
When you’re ready to create something fully unique, our custom home builder services bring your ideas to life. Whether it’s a new detached unit, expansion, or full home, we tailor every project around how you live.
We guide you through:
- Concept & architectural planning
- Budget forecasting
- Material selection
- Construction & final walkthrough
You’ll get clear communication, predictable timelines, and transparent pricing.
