FAQ

Junior ADU Questions

A Junior ADU (JADU) is a small residential unit up to 500 square feet that's created within your existing home. It must include a cooking facility (can be an efficiency kitchen) and can share a bathroom with the main house. JADUs require owner-occupancy of either the main home or the JADU.
JADU costs vary depending on your existing space, whether plumbing needs to be added, and the level of finishes. Because you're converting space within your home rather than building new, JADUs are the most affordable ADU option. Contact us for a free estimate.
Yes! California law explicitly allows one JADU plus one ADU on a single-family lot. This means you could have your main home, a JADU within it, and a detached ADU in your backyard — maximizing your property's income potential.
Yes, JADUs require owner-occupancy — the owner must live in either the main home or the JADU. This is different from standard ADUs, which have no owner-occupancy requirement under AB 976.
Any room within your existing home can potentially become a JADU: spare bedrooms, bonus rooms, basement areas, or even attached garage space. The key requirement is that it must be within the existing walls of your home.
Yes, JADUs must have a separate exterior entrance. However, they can also have an interior door connecting to the main home, which is ideal for multigenerational families.
JADUs are allowed to have an 'efficiency kitchen' which includes a sink, cooking appliance (cooktop or range), counter space, and a refrigerator. It doesn't need to be a full kitchen — this keeps costs lower while still providing independence.
JADU rental income varies by location, but in San Diego County, studios and efficiency units typically rent for varies. Because JADU construction costs are relatively low, the return on investment is excellent.
JADUs created within existing space generally don't need fire sprinklers if the existing home didn't have them. However, they do need hard-wired, interconnected smoke and carbon monoxide detectors. Vision ADU handles all code requirements.
Yes, an attached garage can be converted into a JADU as long as the finished unit is 500 sq ft or less and within the existing structure. This is one of the most popular and cost-effective JADU options we build.
