ADU Construction in San Marino
San Marino ADUs planned around the driveway that carries every delivery, finished with hardened walls, rated vents and tempered glass.
If tree limbs arch over a San Marino driveway, their clear height decides which truck can carry roof trusses and wall sheathing toward the back of the lot. We measure that height, the width between the house and the fence, and any bend in the path before a footprint is fixed. When a boom truck cannot pass, trusses come in smaller pieces and are carried in by hand.
Sizing deliveries to the path
A narrow or low path changes the order of delivery more than the materials do. Lumber arrives in bundles a few workers can shoulder, drywall rides on a cart with wide soft wheels, and concrete reaches the forms through a line pump hose laid along the side yard. Fiber cement siding is heavy and brittle at the ends, so it travels flat on padded racks and is cut beside the unit. Long pieces such as ridge beams are staged at the curb on the day they go up, which keeps the drive open for the house the rest of the time.
Leaving the drive as it was
Mats spread over the driveway and any lawn along the path share out the weight of loaded carts and protect the surface. Where roots run under the drive, heavy equipment stays off them and any utility trench near a trunk is dug by hand. Gates and fence panels that must come down for the build are numbered and stored. At the end, a magnetic sweeper pulls stray nails from the path and the mats come up, so the way that served the build turns into the walk to the unit's front door.
ADU Construction in San Marino: common questions
Mapping decides it for San Marino: a parcel inside a state fire hazard zone takes the wildfire chapter, and we read the address against that map early. Our units go up with noncombustible siding, ember-resistant vents and tempered glazing regardless, so a mapped result brings extra code notes to the drawings while the delivery plan stays the same.
The site plan for a San Marino unit marks the path materials will take and any tree it passes under, and the structural sheet shows how trusses split into pieces small enough to carry. A qualifying single-story unit sits within the package, and anything taller is scoped apart.
It can be done when the parcel holds both buildings and the city approves the order. Sharing one driveway for two jobs needs a schedule, so framing for the unit and framing for the house arrive on separate days without blocking the drive. One trench can then carry utilities to each.
