Frequently Asked Questions (FAQ)

When is a geotechnical report required in the unincorporated area of LA County?
What triggers the requirement? Steepness? Fill? Scope of work?
Would a Geo report be required to partially rebuild a fire damaged structure on a 1940's era filled pad?


Typically the need for a geotechnical report is determined by the building plan checker reviewing the project. Soils in areas of questionable stability that are prone to landslides, liquefaction, and all hillsides require a geotechnical report. Please contact the Building and Safety Office indicated below for more information regarding the specific requirements for your project.
