Frequently Asked Questions (FAQ)

Question:
Are there any specific foundation underpinning requirements for a two story addition on an existing 12" footing.

ANSWER:
1)Buildings in certain areas of Los Angeles County are regulated by the Los Angeles County Department of Public Works (DPW). The address you provided is an incorporated area not served by the Los Angeles County DPW Building and Safety Division. Therefore, your question should be submitted to the City of Santa Clarita.
2)The underpinning application you are referring to is a common methodology to reinforce existing footings supporting a second story. However, in areas served by the County of Los Angeles Department of Public Works the County of Los Angeles Building Code (LACBC) has no provisions or details for such construction and the LACBC requires a structural design and details to be provided by a licensed civil/structural engineer or a licensed architect in the State of California.
