Frequently asked questions
- Does every state require security deposit interest?
- No. Only some states and cities require landlords to pay interest on security deposits. States such as Connecticut, Massachusetts, and New Jersey have such laws; many others do not.
- How is the interest rate set?
- The rate is typically set by statute or ordinance and may change annually. Common methods include a fixed statutory rate or a rate tied to a savings-account benchmark.
- When must the deposit and interest be returned?
- Most jurisdictions require return within 14–30 days of lease termination, along with an itemized deduction statement. Missing this deadline can result in penalties of double or triple the deposit amount.
