ADU Construction in Claremont, From the Street to the Footing
Claremont ADUs planned around the side yard route, so concrete, lumber and steel get to the rear yard and every footing is poured in one go.
The narrowest point between the street and the back of a Claremont lot shapes every step of building a backyard unit. Our tape checks the side yard at the gate, under the eave and past any meter on the wall. Enough clear width for a compact loader means the footings can be dug by machine. A tighter path means hand digging, a line pump for the concrete and lumber carried in by hand, which changes the schedule more than the design.
Getting concrete to the footing
Footing concrete must arrive at the rear of the lot in one continuous placement so no cold joint forms partway along a footing. Where a truck cannot back in, a line pump pushes concrete through hose from the street, and the hose route is planned so it does not crush a sprinkler line or crack a walkway. Rebar and anchor bolts are carried in ahead and tied in the trenches, then inspected. Only after that inspection passes is the pump booked and the pour made, start to finish in a single day.
Protecting the house along the way
The path that carries materials also passes the main house foundation, the sewer lateral and sometimes a gas line. We lay plywood over lawn and pavers, keep heavy loads off any shallow pipe and never stack lumber against the house wall, where it could trap moisture against the sill. If materials have to sit in the driveway, they are staged so a car can still get out. When the unit is finished, the route is restored, and any edging or irrigation damaged along the way is replaced.

ADU Construction in Claremont: questions
A Claremont unit rests on a slab with reinforced footings around its edge, and the footing size comes from the soils report. If the side yard is tight, those footings are dug by hand to the same depth a machine would reach. The anchor bolts and hold-downs that tie the walls down are set in the forms before the concrete arrives.
It depends on the footing we find at the garage wall. We measure its depth and width and check for steel and cracking. If sound, it gets new anchors and plywood bracing, and a weak one is replaced in reinforced sections. A garage beside the driveway is also the easiest unit to reach with materials, which keeps the work simple.
Coverage extends to a Claremont unit kept to a single story, with its floor area held at 500 square feet or under, whether detached, attached or converted. The site plan for these sets marks the access route and the staging area beside the footprint, so the reviewer can see how work reaches the back of the lot. Past those limits, a design is quoted in writing following a site visit.
