ADU Construction in Northridge
ADUs and garage conversions in Northridge, planned around the route materials take past an older house and the utilities it already has.
Before any lumber reaches the back of a Northridge lot, we walk the path it will take. A driveway beside the older house, a side yard between fence and wall, or a gate at the rear decides how framing, drywall and a concrete pour arrive, and how wide the gap must stay so the original eaves, windows and gutters are not scraped along the way. That route shapes the build schedule from the first day.
Getting concrete and framing past the house
When a truck cannot back down the driveway, concrete for the slab is pumped through a hose laid along the side yard, and the forms are set before the pump is booked. Framing lumber comes in bundles carried by hand or on a cart, so the cut list is ordered in lengths that turn the corner. We protect the older house as we go: plywood over the lower siding, padding on the downspouts, and boards across any original brick walk that a loaded cart would crack.
Keeping the main house livable during the build
The house in front stays in use while the unit goes up behind it. We keep one clear walkway to the back door, fence the work area, and plan the utility tie-ins as short shutoffs announced ahead. Trenching for the sewer and power runs is backfilled and compacted soon after it is dug, so the yard is never left open across the path to the garage. Any plaster or trim inside the old house that sits near a new connection is covered before the wall is opened.

ADU Construction in Northridge: common questions
The tie-in begins with what the old house already has. If its panel is small, the new unit may feed from an upgraded main service or from its own meter, depending on the load. The sewer line is scoped by camera from the cleanout, and the water supply is checked for pressure at the far end of the yard.
It can, when the structure is worth keeping. We look for a footing under the slab, termite or rot damage in the sill plates, and enough ceiling height for a living space. A Northridge garage that fails those checks can be rebuilt on its footprint, which keeps the yard layout the house was planned around.
The unit borrows the main house's proportions. We copy the roof slope and overhang, choose siding with the same exposure, and size the windows to the same height-to-width ratio as the originals. Paint colors are matched from a scraped sample of the house trim, so new and old sit together without looking forced.
