What to bring into the first discussion.

Walk through a normal day on the plan. Test arrival, groceries, cooking, dining, bathing, laundry, sleeping, storage, cleaning, and access to mechanical equipment.

Look closely at the existing conditions.

Study daylight and privacy together. Window size and placement affect furniture, neighboring views, heat, ventilation, and the relationship between the ADU and main house.

Connect the decision to the full scope.

Choose materials with installation and maintenance in mind. Exterior exposure, wet areas, flooring transitions, cabinetry dimensions, lighting, and trim details should be coordinated with the actual products.

Use current sources and responsible professionals.

Connect the architecture to the yard. Entries, paths, drainage, equipment, refuse storage, planting, fences, and private outdoor space all compete for limited area on some Costa Mesa lots.

Read the related Costa Mesa ADU services, cost guide, and permit guide for the construction context.

Choose a practical next step.

Document selected products and unresolved allowances. A reference image communicates direction, but the drawings and written specifications control what the contractor is expected to install.

Return to Costa Mesa ADU Contractor or call (949) 503-8004 when you are ready to discuss the property.
