The starting point. A complete proposal connects utilities, access, drainage, and restoration to the exact building location and existing home.

Start with the facts the property can show.

Locate electrical equipment and assign who confirms capacity, upgrades, metering, and the new route. Use the Huntington Beach ADU services page to compare project types.

Walk the site before settling the drawing.

Investigate water and sewer paths around slabs, rooms, paving, planting, pools, and grade changes.

Put the finding into the construction scope.

Study roof runoff, lot drainage, coastal weather exposure, low points, new paving, and neighboring elevations together. The cost and proposal guide helps keep inclusions, exclusions, and allowances visible.

Keep official answers tied to the actual proposal.

Plan deliveries, staging, demolition, protection, waste removal, worker access, security, and continued household circulation. Check current information through the City ADU page and California HCD.

Make the next action specific.

Separate confirmed work from allowances, exclusions, and investigations, then record how each finding changes the scope. Return to Huntington Beach ADU Contractor or call (714) 477-7345.

Carry the field findings into the written scope.

A useful utility sketch starts at the existing service points and follows each likely route to the new living space. Mark the electrical panel, water entry, sewer cleanouts, gas equipment when relevant, drainage paths, meters, and accessible working areas. Note hardscape, planting, walls, and occupied spaces that a route may disturb. Capacity and connection decisions belong to the responsible professionals and providers; the contractor still needs to show how the resulting work enters the construction scope. Include trenching, patching, testing, equipment clearances, and restoration so the visible finish is connected to the work below it.

Check the current source, then the property.
