Cal. Civ. Code § 1946.3

(a) This section is known, and may be cited, as the Social Security Tenant Protection Act of 2025.
(b) For purposes of this section:
(1) “Residential real property” means any dwelling or unit that is intended for human habitation, including any dwelling or unit in a mobilehome park.
(2) “Restored” means a reinstated Social Security benefit that has been received by the Social Security beneficiary.
(3) “Social Security hardship” means a loss of income due to an interruption in the payment of Social Security benefits due to the action or inaction of the
federal government.
(c) Notwithstanding any other law, a tenant of residential real property may assert Social Security hardship as an affirmative defense in any unlawful detainer proceeding based on the nonpayment of rent. A tenant that asserts Social Security hardship as a defense shall provide evidence of all of the following to the satisfaction of the court:
(1) That Social Security benefits typically received by the tenant’s household have been terminated, delayed, or reduced due to no fault of the tenant.
(2) That the Social Security hardship prevented the tenant from paying the unpaid rent alleged in the unlawful detainer action.
(d) If the tenant successfully provides all evidence required by subdivision (c) the court shall stay the unlawful
detainer action until the earlier of either of the following:
(1) Fourteen days after the tenant’s Social Security benefits are restored.
(2) Six months after the stay is issued.
(e) (1) This section does not relieve the tenant of their obligation to pay past due rent.
(2) Within 14 days of their Social Security benefits being restored by the Social Security Administration, a tenant shall do one of the following:
(A) Pay all past due rent.
(B) Enter into a mutually agreed upon payment plan with the owner of the residential real property.
(f) If the tenant has complied with paragraph (2) of subdivision (e), the court shall restore the tenant to their former estate or tenancy and either dismiss the unlawful detainer action with prejudice or set aside the judgment against all named and unnamed defendants in the action.
(g) By January 1, 2027, the Judicial Council shall adopt or modify forms, as needed, to implement this section.
(h) The affirmative defense created by this section does not apply to any unlawful detainer action other than an action based on the nonpayment of rent.
(i) This section does not prohibit or preempt the Governor from using existing emergency powers to declare a moratorium on evictions for individuals experiencing Social Security hardship or from taking any other emergency actions.
(j) This section shall remain in effect until January 20, 2029, and as of that date is repealed.
