ADU Construction in Arcadia, Sited by the Service
Arcadia ADUs placed around the overhead service drop, the electrical panel and the sewer connection, with clearances and trench routes settled before design.
Overhead service wires crossing an Arcadia backyard can rule out a spot for an ADU before anything else does. Code requires clearance between those wires and any roof beneath them, so a unit cannot sit under the drop unless the line is raised or moved underground. We trace the service from the pole to the meter, note where the panel sits, and mark the strip the wires cover before sketching where the unit might stand.
Moving the drop or going underground
When the preferred spot sits under the service drop, the utility can reroute the wires, or the service can convert to an underground feed in conduit. Either change needs the utility's approval and a new or relocated meter base, and the main panel may be upgraded in the same step if the house and the unit together need more capacity. A load calculation settles that question. The feeder from the panel to the unit then travels underground in conduit, buried as deep as the electrical code requires and kept apart from the sewer and water lines.
Sewer fall and the waste line
Waste from the unit reaches the house connection by gravity when the unit's floor sits above that point and the pipe can keep a steady slope over its length. A long run on level ground can bury the far end too deep, and a unit lower than the connection needs an ejector pump with its own circuit and alarm. We expose the existing line with a small hole to read its depth, then plot the new run with cleanouts at each change in direction. The city's building department reviews the plumbing and electrical layout with the rest of the drawings.

ADU Construction in Arcadia: questions
Outside the strip the service wires cover, inside the setbacks, and high enough that waste can drain toward the house by gravity. Where an Arcadia lot slopes, we then look at what each remaining spot asks of the foundation, from a plain slab to piers, and show you the comparison.
For a single-level unit within 500 square feet, yes, ready for plan check. An Arcadia set for a lot with overhead service needs the site plan to show the wires and their clearance above the new roof, and we include that. Building it, and any engineering for a grade, are separate quotes we write after seeing the lot.
Utility work can lead: rerouting a service drop, a panel upgrade, or a long trench for power and sewer. A pump for a low unit adds equipment and a circuit. A sloped spot also asks more of the foundation. The quote keeps utility items apart from the structure.
