ADU Construction in Whittier, Starting in the Garage
Whittier garage-to-ADU conversions measured from the ceiling height down, with the slab checked, a kitchen fitted inside and plans for city review.
Our tape goes up before it goes across in a Whittier garage that might become an ADU. Clear height from the slab to the underside of the ceiling joists tells us whether a finished room fits once a new floor, insulation and drywall are added, and whether ducts or a light fixture will crowd the headroom. Height sets the floor plan, so we take it at several points before any talk of layouts.
Floor, ceiling and the old door
If the slab sits lower than the house floor, we can raise it with sleepers and a subfloor, which also leaves room for a moisture barrier and drain lines. Where the joists hang low, a vaulted ceiling with rafter ties may win back height. Studs and a header close the car opening around a window and an entry door, and the new wall gets a footing tied to the existing slab edge. Each of these steps depends on that first height reading, so it is taken before anything else is planned.
A kitchen fitted inside the old garage
A two-car garage gives a nearly square room, which suits an L-shaped kitchen in one corner with the living area across from it. We put the sink on the wall toward the house sewer so the trench through the slab stays short, and run the range along the adjoining wall with a hood ducted out through the side. A bath and bedroom fill the back half, and a pocket door between them saves swing space. Because the walls already stand, layout choices center on where plumbing can cross the slab.
ADU Construction in Whittier: questions to settle first
A converted Whittier garage holds a kitchen with a sink, a full range, a fridge and a dishwasher in an L, with a short counter left for prep and a small table nearby. Detached units built new can go larger. We place each appliance on the plan at actual size so the corners and the aisle work.
Whittier reviewers focus on the floor plan of a converted garage, with ceiling heights and the new door wall drawn in, and on the structural sheet detailing its new footing. Our office prepares the full set around those two, submits it and replies to every correction.
Being close to the house, a converted garage usually needs only a short drain to the lateral, trenched through its slab. A shutoff valve sits where the unit's branch tees from the domestic line, and the old garage circuit is replaced by a feeder sized for the kitchen and heat pump, or by a separate meter if the panel is full.
