A Junior ADU (or JADU) is a new category of dwelling units created by the State of California. There are several distinctions between a standard ADU and a JADU detailed in the table below. The main difference is that a JADU is not required to have a dedicated bathroom.
The first step of JADU is to have an architectural plan if you don’t possess one we can help you connect with one of our trusted Architect partners in your area to get the Architectural Permit set prepared.
We have you covered completely with the engineering required for the JADU. You’re planning to make an investment by increasing your property value. Whatever your needs, our engineers are ready to work with you to understand your vision. Your satisfaction is our top priority, which is why our engineers oversee every step of your project.

The State of California recently adopted legislation (SB 13, AB 68 and AB 881) that defines the standards local jurisdictions can apply to Accessory Dwelling Units (ADU) and Junior Accessory Dwelling Unit (JADU). This legislation is contained in the California State Government Code Section 65852.2. This state legislation supersedes the City’s provisions for ADUs and JADUs as outlined by respective city municipalities. The City’s specific requirements will be examined in early 2020, in the meantime, the provisions of state law, as outlined below, will be used to evaluate applications for ADUs and JADUs. Read more
III. Accessory Dwelling Units and Junior Accessory Dwelling Units on the Same Lot a. Both a JADU in an existing space and a new detached ADU up to 800 square feet, maximum height 16 ft., may occur on the same single-family lot, with some limitations (see CA Gov Code 65852.2.(e)(1)(A) and (B)).
IV. Accessory Dwelling Units and Junior Accessory Dwelling Unit on Multi-Family Residentially Zoned Properties a. Multi-family buildings may add ADUs up to 25% of the existing unit space (example: 4- the unit building would be allowed one ADU), or at least one (1) ADU. These ADUs must meet building code requirements and the existing space must not be currently used for a living (storage units and garages would qualify). 3 Accessory Dwelling Unit and Junior Accessory Dwelling Unit Standards.
b. Spaces required as part of a condition of approval or zoning requirement (e.g. long-term bike storage room) cannot be converted. c. Not more than two detached units may be added to a lot with a multi-family building if no more than 16 feet high with 4-foot side and rear setbacks.
V. Parking Requirements a. No parking for an ADU is required if:
i. Within ½ mile walking distance of public transit.
ii. Located within an architecturally and historically significant historic district.
iii. ADU is part of the proposed or existing primary residence or accessory structure.
iv. When on-street parking permits are required but not offered to the ADU occupant.
v. When there is a car share vehicle located within one block of the ADU.
b. No parking is required for a JADU.
c. No replacement parking for the primary residence is required when a garage, carport or covered parking is converted to an ADU or is demolished to provide an area for an ADU.
To start, a Design Everest consultant will schedule a discussion with you to understand your requirements completely.
Once we understand your needs, we schedule an experienced engineer’s site visit at your property, as scheduled, to inspect the structure.
After the inspection, we’ll tell you if any further engineering is required to enhance the safety and value of the property or if needed a report we will provide you. We can also provide you with the necessary Engineering.
We are a true one-stop engineering shop with expertise in a wide range of specializations in providing residential & commercial services as listed above. Our highly experienced engineers design efficient structures and are always looking for value engineering solutions so that customers pay less in construction, materials, efficiency etc.
Unlike other firms, we leverage technology, and make every effort to get high quality plans delivered in weeks – not months. Hey, who said construction has to be painful?
Our proprietary data system, Design Hub, allows us to efficiently forecast and optimize our resources. This means we can take on a project of any size at any time, while maintaining quality and schedule.
Design Everest was amazing to work with. I had called a few other structural engineers and they all said they were 6-8 weeks out in terms of availability. Design Everest came out the next day and completed a structural inspection in a very professional manner. They also followed up multiple times to make sure I was satisfied with their work and to see if I understood everything. This was the second time I've used them and I've now told my friends about them. Highly recommend! Jessica and Marcus were great to work with.
