California Guarantor / Co-Signer Addendum
Add a guarantor or co-signer to a California residential lease. The guarantor promises the tenant’s rent and other lease duties. This paper does not make the guarantor a tenant and does not rewrite Cal. Civ. Code § 1950.5 (AB 12, effective July 1, 2024).
- Landlord, tenant, and guarantor should all sign.
- The guarantor is not an occupant unless named on the lease.
- Deposit-return rules still bind the landlord (21 days).
