Now Build 2 ADUs At Your Property in California

With the incorporation of the new California ADU construction rules & guidelines, a single family residence is allowed to construct two separate ADUs, but with the condition, one being a Regular and the other one a Junior ADU (JADU). It should be a ‘single family zoned’ property. The JADU can be built by converting a part of the existing residence. Now coming to the technical specification, the Junior ADU cannot be more than 500 sq. ft. in size. This is a prerequisite. Whereas, the Regular ADU can be an attached, detached or an above-the-garage unit of 800-1000 sq. ft. in size and with a permissible ceiling height of 16’. If it is a fully detached unit, it should follow or maintain a setback of 4’ from the rear & side, 5’ from the nearest property lines and 10’ from the main building. This is how you can get additional square footage at your residence for a comfortable and spacious living with family members. Two ADUs at one residence amounts to a good amount of space for a family that is growing in size. It is not possible to get such a lavish amount of space through a room addition or interior conversion.
