ADU Construction in San Dimas
San Dimas ADUs planned around how roof trusses, lumber and concrete reach the rear of a cleared lot, with staging set before the main rebuild.
We stand at the curb of a San Dimas lot and work out how roof trusses will reach the rear before a backyard unit is drawn. Trusses are long and cannot bend around a corner, so the route needs a straight run or room for a small crane to lift them over. On a lot cleared after a fire, that path is open, and the rebuild order decides how long it stays clear.
Crane, carry or cut on site
A straight driveway to the back lets a truck drop trusses beside the slab. Where the route turns, a crane can set them from the street, which needs approval to use the lane and a swing path clear of overhead wires. If neither works, the roof is framed with rafters cut on site, which takes more labor at the frame stage. We price whichever method fits the lot and put the reasoning in the written schedule, so the choice is visible before the order is placed.
Staging two buildings on one lot
When the ADU and the main house rise together, the lot is divided before the first delivery. One area holds covered lumber, another stays clear for concrete, and the lane to the rear is kept open until the roof of the unit is on. San Dimas reviews the site plan with that lane drawn, and inspections follow every stage of the build. If the main house goes first, we leave a gap in its fencing and planting so materials for the unit can still pass through.

ADU Construction in San Dimas: questions
If San Dimas permits the unit first, building it early keeps the lane clear for its trusses and concrete while nothing else stands in the way. We finish and final the small house, you move in, and the crews turn to the main structure on the rest of the lot.
For San Dimas, the package fits a single-story unit with an interior of 500 square feet or under. We place the unit on the site plan with the delivery lane beside it, since a reviewer here will read both together. Anything outside the package is quoted after we check the lot.
A conversion avoids moving big material to the rear, since the shell is already there. We cut a small test patch in the slab, see how the studs are braced and climb into the rafters to judge whether the shell can reach a dwelling standard, then compare that price with framing a new unit.
