Excavation contractor in Fontana, CA
Fontana was laid out in large parcels long before the tracts arrived, and a lot of those big lots are still there. Verdemont Excavation sends Fontana requests to a licensed contractor who handles the two kinds of work that come out of that history: ADUs and lot splits on wide older lots in south and central Fontana, and pools in the newer tracts north of the 210.
California SB 9 lets many single family lots split into two and build up to two units on each, and Fontana’s half acre lots are a natural fit. The excavation side of a split is real work: new pads, a second sewer lateral or septic system, separate utility trenches and a driveway. Budget $12,000 to $30,000 in site work before the first wall goes up on a typical split.
Some of the unincorporated islands surrounded by the city are still on septic, and those owners face county Environmental Health rules for any added bedroom. The soil across most of Fontana is sandy gravel that digs well, which keeps machine hours down on the valley floor.
Dig once on a lot split
On a lot split, put the second sewer lateral and the utility trenches in one open trench where the plans allow it. Digging once instead of three times is the easiest few thousand dollars you will save on the project.

Fontana owners ask
What excavation does an SB 9 lot split in Fontana need?
Usually a new building pad, a sewer lateral or septic system for the new unit, utility trenches for power, water and gas, and a driveway or access easement. Site work on a typical split runs $12,000 to $30,000 depending on lot size and whether sewer is in the street.
How much is a pool dig in a north Fontana tract?
Typically $3,000 to $7,500. The sandy soil digs fast, so most of the cost is access through the side yard and hauling the spoil off at $175 to $400 a truckload.
Does Fontana require a permit for an ADU pad?
The ADU itself is permitted through Building and Safety, and grading for the pad and drainage is reviewed with it. The referred contractor handles the excavation side of the permit and the DigAlert ticket.
