Junior ADU (JADU) Construction in San Jose, CA
A Junior ADU (JADU) is a smaller living unit — up to 500 sq ft — built entirely within the existing footprint of your home, often converting a bedroom or a section of the house, sometimes sharing a bathroom with the main residence.

Junior ADU (JADU) in San Jose
Because a JADU doesn't add new square footage to the home, it's generally the fastest and least expensive path to added living space, and California state law caps JADU permit fees to keep them affordable. We design efficient kitchenette and living layouts that make the most of a compact footprint, typically incorporating an existing bedroom plus a small addition for the entry or kitchenette.
We handle the interior reconfiguration, plumbing and electrical work, San Jose permit submittal, and construction. Because JADUs are built within the existing structure, exterior changes are usually minimal — often just a new exterior door for a separate entrance.
A JADU is a strong option for homeowners who want to add a rentable or family-ready unit without the cost and site work of a detached or attached addition. We'll assess whether your home's layout supports a JADU during a free consultation.
Can I build both a JADU and a separate ADU on the same property?
In many cases, yes — California ADU law allows a JADU and a detached or garage-conversion ADU on the same lot, subject to owner-occupancy rules for the JADU. We'll confirm what's allowed for your specific property.
