This is a homeowner research profile. It is not a paid placement, review, or recommendation.
San Jose lists Ca2Homes in its approved preapproved ADU plan section. The city lists UniADU.com as the website.
What to verify first
- Are you buying plans, construction, or both?
- Is the exact plan still approved by San Jose today?
- Who prepares the site-specific plan?
- Who pulls the permit?
- Who builds the ADU after the permit is issued?
Why this company belongs on your first screen
UniADU / Ca2Homes is one of the names on San Jose's approved preapproved ADU list. That makes it important for homeowners who want the fastest plan review path.
But this choice is different from hiring a full design-build company. You need to know who handles the plans, who handles the site package, and who handles construction.
The listed San Jose plans
San Jose lists two Ca2Homes plans:
- 499 sq. ft. 2 bedroom, 1 bath ADU.
- 747 sq. ft. 2 bedroom, 2 bath ADU.
UniADU public pages list 500 Fit at $4,000 and 750 Comfort at $5,000. These are plan prices, not full construction prices.
Plan price is not project price
A plan set can be useful. But you still need the big items: site plan, permit work, city fees, foundation, utilities, construction, finishes, inspections, and cleanup.
UniADU public pages say the permit can only be issued to the owner-builder or contractor. They also say to consult a contractor before pulling the permit.

- What is included in the plan price?
- What is not included?
- Who prepares the site-specific plan?

Best fit
UniADU / Ca2Homes may be a good first call if you want a San Jose approved plan and you already know you will need a builder or contractor for construction.
It may be a poor fit if you want one company to handle every part of design, permit, construction, and project management.
