Prepare for a Costa Mesa ADU estimate.

What to bring into the first discussion.

Bring the address, current property photos, and any survey, floor plan, permit record, or concept drawing you already have. Label the drawing date so the contractor knows which version is being priced.

Look closely at the existing conditions.

Photograph the route from the curb to the proposed work area, including gates, paving, trees, walls, equipment, and overhead obstructions. For a conversion, photograph every wall, the ceiling, slab edges, utility equipment, and the connection to the main house.

Connect the decision to the full scope.

Write down who will use the ADU, the rooms that matter, desired privacy, accessibility concerns, and the parts of the existing yard or home you want to protect. Those priorities help the team make practical tradeoffs.

Use current sources and responsible professionals.

List open questions instead of guessing. Electrical capacity, sewer route, drainage, property lines, prior alterations, and association responsibilities may need records or professional review.

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

Choose a practical next step.

Call (949) 503-8004 when the basics are ready. A phone conversation can establish the next investigation; it is not a fixed price, permit decision, or construction agreement.
