California Small-Landlord Security Deposit Exception: 2 Properties or Fewer

If you're a small landlord wondering why some sources say the security deposit cap is 1 month and others say 2, the answer is: both are right, depending on how much real estate you own.

The two-part test

AB 12's small-landlord exception applies if both of these are true at the same time:

1. Property count: you own 2 or fewer rental properties, total.
2. Unit count: those properties add up to 4 or fewer units, total.

And you must be a natural person — not an LLC, corporation, or REIT — to use it.

If both boxes check, you can charge up to 2 months' rent as a security deposit instead of the standard 1-month cap. If either one fails, you're held to 1 month like everyone else.

Worked examples

• One single-family home. 1 property, 1 unit. Qualifies — up to 2 months.
• One fourplex. 1 property, 4 units. Qualifies — up to 2 months, on all 4 units.
• One duplex + one single-family home. 2 properties, 3 units. Qualifies.
• Two duplexes. 2 properties, 4 units. Qualifies — right at the limit.
• One fourplex + one single-family home. 2 properties, 5 units. Does not qualify — one unit over the cap disqualifies the whole portfolio.
• Three single-family homes. 3 properties, 3 units. Does not qualify — property count fails even though unit count is low.

Notice the last two: it only takes crossing either number, not both, to lose the exception.

What changes if you don't qualify

Nothing dramatic — you simply can't collect more than 1 month's rent as a deposit on new or renewed leases. If you're currently holding 2 months on an existing tenant and later realize you don't qualify, that's worth a conversation with an attorney about whether and how to adjust, since clawing back held funds raises its own issues.

Check this before every new lease, not once

Your property count can change — you buy or sell a rental, and your eligibility changes with it. Re-check the test each time you sign a new lease, not just the first time you ever calculated it.
