There is a specific exemption from reassessment of real property taxes for transfers from a parent to his or her child, whether during the parent's lifetime or at the parent's death.
That being said, making a gift of real estate to a child prior to death has many negative results, especially if the property has been owned for a long time and has a lot of equity built up in it. This is because a gift of the property is also a gift of the parent's "cost basis" for capital gains income tax purposes, which means that, on the parent's death, there is no "step up" or increase in the cost basis for the child, leaving the child with potentially significant income taxes if the property is sold.
For example, if your mother's cost basis in the property was $100,000, established 20 years ago in 1992, and the property is now worth $500,000, there would be a taxable capital gain on the $400,000 of equity if the property was sold by you after your mother's death. These taxes would be up to 23% to 24% of the equity, including both federal and California state income taxes.
On the other hand, if the property was held by your mother in a living trust and she passed it on 100% to you at her death, the new cost basis in the property would become $500,000 instead of $100,000, meaning that the property could be sold for $500,000 with no capital gains income tax.
Also, if you are contemplating this in order to qualify your mother for Medi-Cal (state paid long term care), making a transfer like this improperly could cause a loss of Medi-Cal eligibility for several months or years, defeating the whole purpose. You should consult with a qualified Elder Law attorney to discuss proper planning options if this is your intent.

Your answer depends on HOW this is done and whether or not your mother retains an interest in the home. Depending on the answer to these questions, you may have gift tax and income tax repercussions, as well. Needless to say, in something this critical, you are going to need to meet with an attorney to make sure that you cover all of the bases and set things up properly so this does not come back to haunt you.

I agree with Mr. Bergman. It could be very foolish if your mother gifts you the property just to save property taxes and you end up having a low income tax basis on it. Your mother can leave you the property under a will or a trust and you can still keep the low property tax basis - but since you will have inherited the property, your income tax basis readjusts (saving you income taxes if you ever sell the property).
Assuming that the house is worth more than $150,000 it makes more sense to have your mother create a trust and leave the property to you under her trust than it does for her to leave it to you under her will (probate fees would most likely be high).
Have your mother contact a competent estate planning lawyer to assist her.
