Identify this tree!

I hope someone can help! My kids and I have moved into a new home in San Diego and have been searching for hours to identify this tree. Here is a little info we do know:

1. Southern California
2. Palmate with 5 leaflets
3. Light gray trunk with small bumps
4. No known fruits

Please see the attached pictures.

Nearest I found:

The Sapotes of Mexico

The leaves are much larger on those but the trunks are similar. This tree does not bear fruit. Here are a few more pictures.

I'm not convinced that your tree doesn't bear fruit. If perhaps "The tree has a habit of molting a few times per year and most of the palmate leaves will drop suddenly leaving the tree nearly bare of foliage.  That is normal for this tree.  New growth is a coppery-red color"[1] then we would have another clue. Certainly it looks like that might happen anyday.
