Soil Report for ADU Projects in Southern California
Most cities and counties require a geotechnical or soils report before approving an ADU permit. GeoTed evaluates site conditions and provides the geotechnical documentation your designer, contractor, and building department need to move forward.
Request a Site ReviewWho Needs This
Homeowners planning a detached ADU, garage conversion, junior ADU, or second unit addition typically need a soils or geotechnical report as part of the permit package. This is especially common for:
- Hillside or sloped lots
- Properties with drainage or settlement concerns
- Lots with expansive soils or undocumented fill
- Projects requiring new footings or foundations
- Sites flagged by city or county grading requirements
What GeoTed Evaluates
GeoTed's ADU evaluations address soil conditions, slope and drainage, and subsurface conditions relevant to foundation design. Where required by project scope or jurisdiction, GeoTed coordinates with licensed engineering professionals.
- Surface and subsurface soil conditions
- Bearing capacity and settlement potential
- Expansive soil risk
- Slope stability and grading history
- Drainage patterns and water infiltration
- Geologic hazards relevant to the site
What to Send GeoTed
Send the project address, planned ADU type (detached, garage conversion, JADU), and any available site plans or prior reports. GeoTed will review the site context and advise on scope and likely next steps.

GeoTed provides ADU geotechnical support throughout Los Angeles, Santa Clarita, Ventura County, and surrounding Southern California communities including the San Fernando Valley, Conejo Valley, Santa Clarita Valley, and the greater LA basin.
Frequently Asked Questions
Does every ADU project require a soil report?
Not always — but many jurisdictions require one, especially for projects involving new foundations, hillside sites, or areas with known geologic concerns. Your building department's plan check comments will usually specify if a soils report is required.
What's the difference between a soils report and a geotechnical report?
The terms are often used interchangeably. A geotechnical report addresses soil and subsurface conditions relevant to foundation design and grading. A geologic report addresses broader site geology and hazards. Some projects require one, some require both.
Can GeoTed provide the report needed for a Los Angeles ADU permit?
GeoTed evaluates site conditions and provides geologic and geotechnical recommendations. Where a stamped engineering report is required, GeoTed coordinates with licensed geotechnical engineering professionals appropriate to the project scope.
