Whittier ADU Construction From the Curb Inward
Whittier ADU construction that plans the public stretch of the route first: curb, sidewalk and parkway protected so trucks and pump hoses can cross.
The first stretch of the route to a Whittier backyard unit is public: the curb, the parkway strip and the sidewalk between the street and the lot. Every truck, pump hose and loaded cart crosses it, so we plan that crossing before the side yard. Walks used by neighbors stay passable, a parkway tree's roots are kept clear of heavy wheels, and the concrete is photographed before the first delivery.
Permits and the public walk
Materials or a bin set on the sidewalk or in the street may need an encroachment permit from the city, and some streets limit where a truck can park and for how long. A concrete pump stands at the curb with its outriggers on pads, and its hose crosses the sidewalk under a ramp cover, so people with strollers or wheelchairs can still pass. Deliveries are booked for the quieter hours of the day, and the curb is swept before everyone leaves. If a city tree stands in the parkway, its trunk is wrapped and nothing is stored over its roots.
From the curb to the side yard
Past the sidewalk, the driveway apron is often thin concrete with little steel in it, so heavy trucks stay in the street and carts take the loads from the curb. Where the apron has to carry weight, steel plates are laid across it. The older house's original front walk and steps are kept off the route altogether, since a chipped step of old concrete or brick is hard to match. At the end of the job, any damage found on the public side is repaired to the city's standard, and the photographs from the first day show what was there before.

ADU Construction in Whittier: common questions
The trench for the unit runs on private ground, from the main house to the backyard, so the public side is touched only if the water or power service from the street must grow. In that case the utility does its own work in the parkway. A load calculation on the panel, a flow reading and a camera run on the lateral tell us beforehand.
Yes, when the garage is sound, and a conversion means far fewer trucks at the curb, since the walls and roof already stand. We test the slab for moisture, open the base of one wall to see the footing and sill plate, and look at whether the rafters can take a ceiling. The old car opening is closed last.
Begin where the eye lands from the yard, the roofline, matching the main house's pitch and the reach of its eaves. Walls follow the house's siding exposure or stucco finish, windows repeat its proportions, and the casing widths are measured on the original. Colors come from the house's body and trim.
