What is a junior ADU (JADU)?

A JADU is a small (often ≤500 sq ft) ADU created within an existing single-family home, typically with its own entrance and efficiency kitchen. Many states have streamlined rules for JADUs.

Does a JADU need a separate permit?

Yes, but the process is often simpler than a full ADU. We prepare the conversion permit and any required engineering.

Can a JADU have a bathroom?

Yes — JADUs typically include a bathroom and efficiency kitchen. We permit the plumbing and electrical for both.
