Frequently Asked Questions

Which states require landlords to pay interest on security deposits?
Some states require interest on security deposits, often with conditions, and the rules vary by jurisdiction. Rates and requirements vary significantly by state — some require deposits to be held in separate escrow accounts, others only require interest payments above a minimum deposit threshold. Always verify current requirements with your state's tenant rights office.
What is the typical interest rate for security deposits?
Required deposit interest rates, where they exist, vary by state. Some states set or update required deposit interest rates periodically; check your state's agency page for the current rate and date. For commercial leases, the interest rate (if any) is a matter of negotiation and should be specified in the lease itself.
What happens if my landlord doesn't pay interest on my deposit?
In states that require deposit interest, the consequences of not paying it vary, so check your state's rules and ask a local attorney what applies. Whether unpaid deposit interest affects a landlord's ability to withhold for damages depends on state law and the facts; consider having an attorney review. Check your state's specific statutes for the remedies available to you.
