What to bring into the first discussion.
Costa Mesa states that ADUs cannot be used as short-term rentals and are subject to a restriction against rentals shorter than 31 days. Check the current City FAQ and project documents before relying on that summary.
Look closely at the existing conditions.
Longer-term occupancy changes practical design decisions. Storage, laundry, utilities, acoustics, mail, refuse, parking context, outdoor access, and privacy deserve attention.
Connect the decision to the full scope.
A contractor does not provide tax, lease, financing, insurance, or landlord-tenant advice. Bring those questions to the qualified advisers responsible for them.
Use current sources and responsible professionals.
If the unit is for family, plan the same daily needs even when no rent is charged. Independence, safety, accessibility, and future changes in use can still influence the work.
Read the related Costa Mesa ADU services, cost guide, and permit guide for the construction context.
Choose a practical next step.
Keep current regulatory answers with the project file. A building permit does not replace compliance with rental, occupancy, deed, or other operating requirements.
