Yes, indeed. Homes in Los Angeles typically have foundations that are built on soft clay soil that expands during our rainy season and contracts during our dry season. This back-and-forth movement often causes concrete foundations to shift and crack. Moreover, the strong seismic activity and violent shaking that is so common to Southern California puts incredible stress on already-brittle foundations, easily cracking them in multiple places. Finally, other local geographical natural forces such as water runoff also damages local foundations. If your home was subjected to earthquakes and water runoff, you may need basement waterproofing, leaky basement repair, basement wall sealing, basement wall cracks repair, or in the worst case, a full foundation replacement!
