Tenant screening and security deposits in California

Short answer

Since July 1, 2024, most California landlords can charge a security deposit of at most one month's rent (AB 12); small landlords with no more than two properties and four units can charge up to two months, except to service members. Deposits must be returned, with an itemized list of any deductions, within 21 days after the tenant moves out. Screening must follow fair housing law, which protects tenants who pay with housing vouchers.

Common questions

What is the maximum security deposit in California?

Generally one month's rent since July 1, 2024 (AB 12). Owners who are individuals (or certain LLCs or family trusts) with no more than two rental properties and four units can charge up to two months, except to service members.

How long do I have to return a security deposit in California?

21 days after the tenant moves out, with an itemized statement of any deductions.

Should I accept Section 8 vouchers?

In California you cannot refuse a tenant because they pay with a housing voucher; source of income, including vouchers, is protected (SB 329). You can still apply the same screening to the tenant's share of the rent.
