Why ADU Recompaction Is Critical for Building a Safe, Code-Compliant ADU in California
Building an ADU involves more than design and framing—your structure is only as strong as the ground beneath it. ADU recompaction is a crucial first step that ensures your soil meets California’s strict density, safety, and inspection requirements.
What Is ADU Recompaction?
Recompaction is the process of reworking and densifying soil to create a stable pad for an ADU foundation. Over time, soil can become loose, disturbed, or uneven due to erosion, old landscaping, utility installations, or previous structures. Recompaction restores consistent density across the entire build area.
Why California Requires Recompaction
County inspectors evaluate soil stability before approving an ADU foundation. Without proper compaction, issues such as settling, cracking, or foundation shifting can occur—leading to costly structural repairs.
