California's ADU market is booming — and every new unit needs four utilities run from the main house. Apex bores them all trenchlessly, protecting your landscaping, driveway, and existing hardscape.
One contractor for all four underground utility connections — less coordination, less disruption, faster completion.
Electrical conduit from main panel to ADU sub-panel — bored under driveways, paths, and landscaping.
Gravity or pressurized sewer lateral from ADU to main line — bored or trenched per site conditions.
Domestic water service lateral from meter or main to ADU — sized and installed per plumbing code.
OQ-certified gas service installation from main line to ADU meter — including pressure test and riser.
Each utility has different requirements. Here's how we handle each one.
