Summary

Berkeley caps residential security deposits at two months rent for unfurnished units and requires landlords to pay annual interest to tenants, layered atop California Civil Code Section 1950.5 protections.

1950.5. (a) This section applies to security for a rental agreement for residential property that is used as the dwelling of the tenant. (b) "Security" means any payment, fee, deposit, or charge imposed at the beginning of the tenancy. (c) (1) Except as provided in paragraph (2), (3), or (5), a landlord shall not demand or receive security, however denominated, in an amount or value in excess of an amount equal to one month's rent, in addition to any rent for the first month paid on or before initial occupancy. (2) This subdivision does not prohibit an advance payment of not less than six months' rent if the term of the lease is six months or longer.

Full Breakdown

Berkeley Municipal Code Chapter 13.78 mandates that landlords pay annual interest on security deposits held longer than twelve months. The Rent Stabilization Board publishes the interest rate each December based on local bank rates. Deposits remain capped at two months unfurnished or three months furnished consistent with state law. Landlords must return deposits within 21 days of move-out with itemized deductions. Berkeley layers the interest requirement onto Costa-Hawkins-protected pre-1995 stock without preemption issues, since interest rules are not rent control.

Violations & Fines

Failing to pay deposit interest, withholding without itemization, or holding amounts beyond legal caps exposes landlords to twice the wrongful retention plus statutory damages and attorney fees.

Frequently Asked Questions

What is the current interest rate?
The Rent Board publishes the rate every December. Recent rates have ranged from one to three percent depending on prevailing local savings rates.
Does AB 12 affect Berkeley caps?
California AB 12 lowered furnished caps to one month for most landlords starting July 2024. Berkeley applies the more protective state limit alongside its interest rule.
