Plan utilities and site work for a Costa Mesa ADU.

What to bring into the first discussion.

Locate the main electrical equipment and identify who evaluates capacity, required upgrades, metering, and the route to the new unit. Do not infer available capacity from panel size or neighborhood age alone.

Look closely at the existing conditions.

Find likely water and sewer connection paths and note cleanouts, slopes, slabs, landscaping, and rooms that may be affected. The shortest line on a plan may not be the least disruptive construction route.

Connect the decision to the full scope.

Watch how water moves across the lot. Roof drainage, paving, planting, low points, neighboring grades, and new foundations need a coordinated drainage discussion.

Use current sources and responsible professionals.

Plan the physical job: demolition, tree and surface protection, temporary fencing, delivery space, material storage, waste removal, worker access, and continued access to the occupied home.

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

Choose a practical next step.

The proposal should distinguish confirmed site work, allowances, exclusions, and restoration. If an investigation is pending, name its owner and the decision that depends on the result.
