California Code, Welfare and Institutions Code - WIC § 11009.1

The value of free board and lodging supplied to a recipient during a temporary absence from his home of not more than one month, shall be considered an inconsequential resource and shall not be deducted from the amount of aid to which the recipient is otherwise entitled.

After an absence of one month, free board and lodging shall be considered income to the extent the value exceeds the continuing cost to the recipient of maintaining the home to which he expects to return.

This section shall not apply to recipients under Chapter 3 (commencing with Section 12000) of this part.
