What to bring into the first discussion.
How do I know which ADU type fits? Compare the household goal with the yard, garage, house, access, privacy, and utilities. A site visit and records review usually narrow the choices.
Look closely at the existing conditions.
What should an estimate include? Ask for the referenced drawings, site work, utilities, building systems, finishes, allowances, exclusions, inspections, and restoration.
Connect the decision to the full scope.
Can a garage always be converted? No. The structure and proposed use need review. Slab, framing, moisture, height, openings, services, and unpermitted work can affect the scope.
Use current sources and responsible professionals.
How long does an ADU take? It depends on design decisions, investigations, City review, selections, procurement, site conditions, inspections, and changes. Ask for dependencies rather than a generic promise.

Choose a practical next step.
Where should I verify rules? Start with the City of Costa Mesa and California HCD, then obtain property-specific answers from the responsible professionals and agencies.
