Common project type
A junior ADU is a distinct planning path, not simply a small detached model. Start with the existing home and proposed living arrangement. Ask the responsible jurisdiction to confirm the classification and current conditions before designing around a size or occupancy assumption.
Compare a JADU with an internal remodel and a full ADU based on how the space will be used. The legal classification may affect the layout and owner responsibilities; a service page cannot determine it for the property.
Draw furniture, circulation, storage and cooking space inside measured dimensions. Discuss whether the bathroom arrangement is compatible with the proposed approval path and household needs.
An internal conversion can affect occupied rooms, systems and privacy. Include those impacts in the scope rather than presenting the work as an isolated miniature home.
No. The catalog shows detached illustrative concepts. A JADU proposal starts from an eligible existing-building context and the authority’s current requirements, not a catalog square-footage match.
Start with the California HCD ADU resources and the responsible local agency. Confirm the rules for the specific proposal rather than relying on an undated summary or a rule copied from another city.
The useful next decision
A preliminary property review can identify available records, missing information, map corrections, and an early fit direction. Professional review still controls final design and approvals.
Share the address and intended use so the conversation starts with the correct context.

These reviewed agency-resource guides do not confirm service availability. Confirm current rules, property records, and agency requirements for the actual address.
