Unlock Your Property’s Potential with an Accessory Dwelling Unit (ADU)

Looking for more space, revenue, or flexibility in your home? An Accessory Dwelling Unit (ADU) in San Jose, California offers a smart solution. Whether you’re building for family, rental income, or future-proofing your property, an ADU crafted by My Construction Group seamlessly blends design, quality, and local expertise.

Why San Jose is Perfect for ADUs

San Jose is a leader in ADU innovation. As of 2025, the city supports fast-track ministerial permitting, reducing approval times dramatically. No public hearings for qualifying projects. The city also offers pre-approved ADU plans, so homeowners can skip long design delays and build quickly. Updated zoning allows detached ADUs with just 4-foot setbacks, maximizing buildable area.

These progressive policies make San Jose one of the most ADU-friendly cities in California — and your property a prime opportunity.

What Is an ADU?

An ADU, often called an in-law unit or granny flat, is a self-contained living space on the same lot as a primary home. It can be:

• Detached — a standalone structure in your backyard
• Attached — an extension of your existing home
• Converted — such as a garage or basement turned into a living unit
• JADU — a Junior ADU, up to 500 sq ft, inside your existing home

ADUs are great for extended family, rental income, or future resale value.

The Cost of Building an ADU in San Jose

Building an ADU is an investment — here’s what it costs:

• General cost range:
  • 300–500 sq ft: $160K–$195K
  • 550–750 sq ft: $200K–$245K
  • 800–1000 sq ft: $260K–$300K
  • 1050–1200 sq ft: $310K–$330K
• South Bay overall:
  • Attached ADU: $400K–$750K
  • Detached ADU: $500K–$1.2M
• Per square foot estimates:
  • Attached: $800–$1,000
  • Detached: $1,000–$1,250
• Prefab ADUs: $95K–$180K for the unit alone; full cost may exceed $240K

Permit and city fees add to that — expect approximately $17,000 for a 751–1200 sq ft attached ADU in San Jose.

Despite upfront investment, ADUs offer strong long-term value. Typical ROI in the Bay Area ranges around 62%, with rental income helping offset mortgage payments.

ADUs Deliver Double Value

ADUs are more than extra square footage — they offer lifestyle, financial, and legacy benefits:

1. Versatile Living – Use as a guest suite, home office, or deluxe rental space.
2. Rental Income – In high-demand markets like San Jose, a two-bedroom ADU can rent for $3,500–$4,000/month.
3. Equity Growth – An upgraded ADU can significantly raise your property’s market value.
4. Future Flexibility – Live in one unit and rent the other, or convert for multi-generational living.
5. Resale Appeal – ADUs are increasingly attractive to buyers looking for extra space or rental potential.
