Tennessee Tenant Guidance: Can a Landlord Increase the Security Deposit After Move-In?

Understanding the rules surrounding security deposits is crucial for tenants in Tennessee. One common question is whether a landlord can increase the security deposit after a tenant has already moved in. This guidance will provide a clear, state-specific answer about Tennessee laws on security deposits and related best practices.


Overview of Security Deposits in Tennessee

In Tennessee, security deposits are governed by state law, specifically found under Tennessee Code Annotated (TCA) § 66-28-301 et seq. Security deposits serve as financial protection for landlords against unpaid rent, damages, or breaches of lease agreements. However, tenants have legal protections regarding how these deposits are handled and regulated.


Can a Landlord Increase the Security Deposit After Move-In?

The simple answer: Generally, a landlord cannot unilaterally increase the security deposit after move-in without tenant consent.

Key Points:

  • Initial Agreement Controls: The amount of the security deposit is established at the time the lease or rental agreement is signed. This amount is typically fixed for the term of that agreement.
  • Lease Terms: Unless the lease explicitly provides for adjustments to the security deposit during the tenancy, landlords do not have the right to demand additional deposits mid-lease.
  • New Lease or Renewal: If the tenant's lease has expired and they are signing a new lease or renewing with modified terms, the landlord may require an additional or increased security deposit as part of the new agreement.
  • Tenant Consent Required: Any increase in the security deposit after move-in must be agreed upon by both parties. The landlord cannot impose additional fees or deposit amounts without the tenant’s approval.

Example Scenarios:

  • If a landlord decides mid-lease that they want a higher security deposit, the tenant may decline, and the landlord must abide by the original agreement until the lease ends.
  • Upon lease renewal, the landlord can propose a higher security deposit, but the tenant has the right to negotiate or refuse, and either party can decline to renew.

Lease Provisions and Notice

Tennessee law does not explicitly regulate increases to security deposits during an ongoing lease but relies heavily on the lease contract and mutual consent. Therefore:

  • Lease Clarity: Tenants should carefully review lease language about security deposits and any clauses about changes during tenancy.
  • Written Agreement: Any changes, including increased deposits, should be documented with a written amendment or a new lease agreement.

Tenant Protections and Best Practices

While Tennessee landlords can request security deposits up to an amount that is reasonable (typically not exceeding one or two months' rent), tenants should be aware of protections:

  • Advance Notice: Landlords should provide tenants with proper notice and explanation of any proposed deposit changes at renewal or new agreement stages.
  • Receipt and Documentation: Tenants must receive written receipts for any security deposit collected or increased, including details of the amount and where it is held.
  • Deposit Use: The security deposit must be held in accordance with Tennessee laws, and landlords must return it, minus any lawful deductions, within 30 days after tenant moves out.

Recommendations for Tennessee Tenants

If you are a tenant in Tennessee facing a security deposit increase request after move-in, consider the following steps:

  1. Review Your Lease: Check if your lease addresses security deposits or allows for increases during the term.
  2. Request Written Notice: Ask the landlord for a written explanation and formal request for any increase.
  3. Negotiate: You may negotiate the amount or timing of any increase or decline to agree until lease renewal.
  4. Do Not Pay Without Agreement: Avoid paying any additional deposit unless you have a written and signed agreement.
  5. Keep Records: Maintain copies of all communications regarding security deposits.
  6. Seek Advice: If unsure about your rights or facing pressure to increase your deposit unlawfully, contact a Tennessee tenant advocacy organization or legal professional for guidance.

Conclusion

In Tennessee, a landlord cannot increase the security deposit after the tenant has moved in without the tenant’s consent or a new lease agreement permitting such an increase. The security deposit amount agreed upon at move-in typically remains fixed through the duration of that lease term. Tenants should remain informed about their lease terms and clearly communicate with landlords about any proposed changes regarding deposits.

Understanding your rental agreement and state laws protects your interests and helps maintain a fair rental relationship. Always seek clarity and put agreements in writing for your security deposits and any financial obligations tied to your tenancy.
