What to bring into the first discussion.
Confirm that the proposed space fits the current state definition and City process before calling it a JADU. Size, location within the residence, facilities, and other conditions distinguish it from an attached ADU.
Look closely at the existing conditions.
Map the rooms and systems that will change. A JADU may affect hallways, bedrooms, kitchens, bathrooms, laundry, storage, ventilation, electrical work, plumbing, and the way the main household moves through the home.
Connect the decision to the full scope.
Discuss privacy honestly. Entries, locks, sound, mail, deliveries, outdoor access, and shared facilities should work for the actual occupants rather than only satisfying a diagram.
Use current sources and responsible professionals.
Ask the City and qualified advisers about current owner-occupancy, deed restriction, rental, and permitting questions for the specific proposal. Website summaries can become outdated as California law changes.
Read the related Costa Mesa ADU services, cost guide, and permit guide for the construction context.
Choose a practical next step.
A contractor proposal should name the existing-condition work, protection, system modifications, finish scope, inspections, and restoration. Compare that complete work with other ADU choices.
