A junior ADU is a 150 to 500 square foot unit built inside an existing single-family home. In Jamul the same work goes by several names, including JADU, junior ADU, attached ADU, in-law unit, or mother-in-law suite, and the permitting path is the same for all of them.

A JADU is limited to 500 square feet, must sit inside a single-family residence (an attached garage counts), needs an efficiency kitchen and its own entrance, and can share a bathroom with the main home. A full ADU can be attached or detached, needs complete independent living facilities, and in the City of San Diego is listed from 150 to 1,200 square feet. A JADU cannot be sold separately from the house. Owner occupancy for a JADU depends on whether it shares sanitation with the main home. A full ADU cannot carry a local owner-occupancy rule.

A junior ADU conversion in San Diego County typically runs $50,000-$90,000 depending on whether you share the main home bathroom or add a half-bath, the kitchenette scope, and the interior finish level. The licensed pro you hire confirms the price in writing. Garage Convert SD sets no prices.

You can rent a JADU, but occupancy rules are not the same as a full ADU. If the JADU shares sanitation with the main house, the owner must live in either the house or the JADU. If the JADU has its own bathroom, that owner-occupancy rule does not apply. Government agencies, land trusts, and housing organizations have a separate waiver. A recorded deed restriction also bars selling the JADU apart from the house. Full ADUs cannot be given a local owner-occupancy requirement. Cities can still require rentals of 30 days or longer.

No. A JADU can share a bathroom with the main home if the unit has interior access to it. If you want a private bathroom within the JADU footprint, a half-bath can be added within the 500 square foot limit. The licensed pro you hire confirms the plumbing scope in writing.
