For a North Hills family with an adult child ready for a kitchen of their own, a backyard ADU is the project we price first. A bedroom attached to the house shares the hallway, the thermostat and the noise. A separate unit gives that person a door, a bath and a stove, while the parents stay just across the yard. The rear of the lot needs open ground, a path for utilities and enough room to meet setbacks.

Running utilities to the back of the lot

Water, sewer, power and gas all have to reach the new unit. We trace where the main sewer line leaves the house and check whether the rear of the lot sits high enough for the drain to flow by gravity, or whether a pump is needed. A subpanel fed from the main service can power the unit, unless the load calls for a separate meter. Trench routes are planned around trees and the patio, and the yard is put back once the lines are inspected and covered.

Permits and the build sequence

North Hills sits inside Los Angeles city limits, which puts the permit for a backyard unit with LADBS after plan check. The review covers distance from the side and rear lines, the height of the unit, fire separation from the main house and the path firefighters would use to reach its door. Once approved, the slab is poured, walls go up and the roof is closed in ahead of plumbing, wiring and finishes. The family carries on in the main house the whole time, with work kept to the back of the property.
