Cal. Educ. Code § 22360.5

(a) The board may include in any investment program established pursuant to Section 22360 a procedure whereby a member may obtain 100 percent financing for the purchase for a single-family dwelling unit in accordance with the following criteria:
1. (1) The member shall obtain one loan secured by the purchased home, pursuant to Section 22360, and a second personal loan secured by a portion of the accumulated retirement contributions in the member’s individual account. The personal loan shall only be used for the purchase of the member’s principal residence and not for a loan to refinance the member’s existing mortgage.
2. (2) The loan secured by the purchased home shall be consistent with the requirements imposed by Section 22360.
3. (3) In no event may the personal loan secured by the accumulated retirement contributions in the member’s individual account exceed the lesser of 50 percent of the current value amount of the accumulated retirement contributions or fifty thousand dollars ($50,000).
4. (4) If two members are married, the personal loan secured by the sum total of accumulated retirement contributions in both members’ accounts shall not exceed 5 percent of the loan.
5. (5) The pledge of security under this section shall remain in effect until the personal loan is paid in full.
(b) The pledge of security under this section shall take binding effect. In the event of a default on the personal loan secured by the member’s retirement contributions as authorized by this section, the board shall deduct an amount from the member’s accumulated retirement contributions on deposit and adjust the member’s accumulated retirement contributions as necessary to recover any outstanding loan balance prior to making any disbursement of a refund or a lump-sum distribution.
(c) In the event of a default on the personal loan by a member, the board shall deduct the monthly principal plus appropriate interest from the member’s benefit, when the member begins receiving a benefit, until the loan is paid in full.
(d) In the event of a default on the personal loan by a member receiving a benefit, the board shall deduct the monthly principal and interest from the member’s benefit until the personal loan is paid in full.
(e) The secured personal loan permitted under this section shall be made available only to members who meet eligibility criteria as determined by the board.
(f) In the event of a refund or lump-sum distribution of the accumulated retirement contributions, the member’s account shall be adjusted as necessary to recover any outstanding loan balance.
(g) If the member is married at the time the home is purchased with a personal loan secured by the member’s accumulated retirement contributions as authorized by this section, then the member’s spouse shall agree in writing to the pledge of security, as to his or her community interest in the amount pledged, regardless of whether title to the home is held in joint tenancy.
(h) For purposes of the section only, “member” means any person who is entitled to receive an allowance funded by the system pursuant to this part or Part 14, notwithstanding any vesting requirement and without regard to present eligibility to retire, and who is not retired or disabled.
