Quick Reference: South Carolina Security Deposit Rules at a Glance

A property manager in Charleston hands back a unit on 30 June. The lease also terminates on 30 June. The manager automatically sets 30 July as the deposit accounting deadline.

That may be earlier than the statutory deadline for the written itemisation and amount due, because § 27-40-410(a) measures that thirty-day period from the later of termination of the tenancy and delivery of possession and the tenant's demand.

The distinction matters, and it is worth understanding precisely. But it should not be read as permission to hold a tenant's money until they ask for it. Section 27-40-410(a) opens with a plain obligation: upon termination of the tenancy, property or money held by the landlord as security must be returned, less amounts properly withheld. The thirty-day clause governs the timing of the written itemisation of deductions and the amount due, not a licence to sit on the balance.

Many secondary sources summarise the deadline as "30 days after move-out," but the statutory text measures the period from the later of termination of the tenancy and delivery of possession and the tenant's demand. The difference affects when your file is late, whether a treble damages claim is available, and how the move-out process should be structured.

Step 1: What the Timing Language Actually Says

The operative sentence is worth reading in full.

"Any deduction from the security/rental deposit must be itemized by the landlord in a written notice to the tenant together with the amount due, if any, within thirty days after termination of the tenancy and delivery of possession and demand by the tenant, whichever is later."

The thirty-day period for the written itemisation and amount due is measured from the later of the events identified in the subsection: termination of the tenancy and delivery of possession, and the tenant's demand.

Those events frequently do not coincide. A tenant who vacates two weeks early has delivered possession before termination. A tenant who holds over has delivered possession after it. And a tenant who never asks for the deposit back has not made a demand.

Two things follow, and they pull in different directions.

The timing language is more generous to a landlord than the "30 days after move-out" shorthand suggests, and a manager calculating from move-out alone may be working to a deadline earlier than the statute requires.

But subsection (a)'s opening sentence still requires the security to be returned on termination, less permitted withholdings. So the practical rule is not "wait for a demand." It is: process the file promptly, and record all three dates so that if a dispute arises about lateness you can show which event actually controlled.

Because the deadline is derived from multiple separate dates, it cannot be a fixed offset from move-out. Recording termination, possession and any demand as three distinct dated fields, and deriving the thirtieth day from the latest, is exactly the kind of rule workflow customization exists to enforce.

Step 2: The Forwarding Address Protection

The same subsection contains a provision most guides mention only from the tenant's side, and it is one of the more useful landlord protections in the Act.

• The tenant's duty. "The tenant shall provide the landlord in writing with a forwarding address or new address to which the written notice and amount due from the landlord may be sent."

• The consequence of failure. "If the tenant fails to provide the landlord with the forwarding or new address, the tenant is not entitled to damages under this subsection provided the landlord (1) had no notice of the tenant's whereabouts and (2) mailed the written notice and amount due, if any, to the tenant's last known address."

Both conditions must hold, and the damages barred are those under subsection (a).

• Condition (1) is knowledge-based. The statute requires the tenant to provide a forwarding address in writing, but the landlord's protection turns on whether the landlord had notice of the tenant's whereabouts, not solely on whether a formal written forwarding address was received. If your team has the tenant's new address from an email, a rental reference request or a forwarding note, that may amount to notice of their whereabouts.

• Condition (2) requires you to actually mail it. The protection is not a licence to do nothing. You must still send the written notice and the amount due to the last known address.

So the correct response to a tenant who leaves no forwarding address is to send the full package to the last address you hold, and keep proof of despatch. That is what activates the protection. Inaction forfeits it.

Step 3: What You May Actually Deduct

Section 27-40-410(a) permits the security to be returned less amounts withheld by the landlord for accrued rent and damages which the landlord has suffered by reason of the tenant's noncompliance with § 27-40-510.

Two categories, and the second is defined by cross-reference.

• Accrued rent. Rent owed at termination.

• Damages by reason of the tenant's noncompliance with § 27-40-510. That is the tenant obligations section, which addresses compliance with building and housing codes materially affecting health and safety, keeping the occupied part of the premises reasonably safe and clean, rubbish disposal, plumbing fixtures, reasonable use of electrical, plumbing, sanitary, heating, ventilating, air conditioning and other facilities and appliances, not deliberately or negligently destroying, defacing, damaging, impairing or removing any part of the premises or knowingly permitting anyone to do so, and conduct that does not disturb neighbours' peaceful enjoyment.

On ordinary deterioration. South Carolina's security deposit statute does not separately define "normal wear and tear." Because deductions must be for damages resulting from the tenant's noncompliance with § 27-40-510, ordinary deterioration that is not traceable to tenant noncompliance generally cannot be withheld, even though the statute does not use that phrase. Property managers should be able to connect each deduction to a specific § 27-40-510 obligation.

That cross-reference is why the condition record matters so much. Every deduction has to be traceable to something the tenant did or failed to do, measured against how the unit started. Dated, photographed records at both ends of the tenancy are what convert an assertion into a defensible deduction, which is what move-in and move-out management is designed to produce.

Step 4: Treble Damages, and What Triggers Them

Section 27-40-410(b) supplies the penalty, and its trigger is more specific than usually reported.

If the landlord fails to return to the tenant any prepaid rent or security/rental deposit with the notice required to be sent by the landlord pursuant to subsection (a), the tenant may recover the property and money in an amount equal to three times the amount wrongfully withheld and reasonable attorney's fees.

Four points for a manager.

• The trigger is the failure to return prepaid rent or the security deposit together with the notice required by subsection (a). The statute treats the money and the notice as a single required package.

• Prepaid rent is expressly included, as well as the security deposit. A failure to return either together with the required notice can trigger the penalty, so the provision is not deposit-only.

• The multiplier applies to the amount wrongfully withheld, not to the deposit as a whole. A landlord who correctly withholds $600 of an $1,100 deposit and wrongfully withholds $500 faces the multiplier on the $500.

• And attorney's fees are statutory, which changes the economics of a small dispute entirely. A $400 disagreement that carries fees is a different proposition from one that does not.

Note also how subsection (a)'s protection interacts. Where the tenant failed to provide a forwarding address, had not otherwise made their whereabouts known, and the landlord mailed the package to the last known address, the tenant is not entitled to damages under subsection (a).

Step 5: The Multi-Unit Disclosure

Section 27-40-410(c) creates an obligation that applies only when two conditions are both present, which is why it is easy to overlook.

Where a landlord (1) rents more than four adjoining dwelling units on the premises, and (2) imposes different standards for calculating security/rental deposits required of different tenants on the premises, then prior to the consummation of the rental agreement the landlord shall either:

• Post in a conspicuous place on the premises, or at the place at which rental is paid, a statement clearly indicating the standards by which the deposits are calculated; or

• Provide each prospective tenant with a statement setting forth the standards.

The consequence of non-compliance is precise. If a landlord fails to comply as to a tenant, the difference between the security deposit required of that tenant and the lowest security deposit required of any other tenant of a comparable dwelling unit on the premises may not be withheld for damages by reason of the tenant's noncompliance with § 27-40-510.

Three points to note.

• The comparison is to a comparable dwelling unit. Not simply the lowest deposit anywhere on the premises.

• The trigger is differing standards, not differing amounts. A landlord who applies the same standard for calculating deposits to all tenants has nothing to disclose. The obligation turns on whether the standards for calculating deposits differ, not merely on whether the dollar amounts differ. A landlord using one month's rent for some units and a flat figure for others may be inside the subsection even where the resulting amounts sometimes coincide.

• And the timing is prior to consummation of the rental agreement. A disclosure produced at move-in is late.

Because the trigger is the interaction between property size and the deposit-setting methodology, this is a lease-template and pricing decision rather than a move-out one. Holding the deposit standard and any required disclosure with the lease through contracts and renewals is what makes compliance provable years later.

Step 6: Two Provisions at the End of the Section

Other damages are preserved. Under § 27-40-410(d), the subsection does not preclude the landlord or tenant from recovering other damages to which he may be entitled under this chapter or otherwise. The deposit remedy is additional, not exclusive, for either side.

And the successor is bound. Under § 27-40-410(e), subject to the provisions of § 27-40-450, the holder of the landlord's interest in the premises at the time of the termination of the tenancy is bound by the section.

That is a diligence point on any acquisition. Because the binding provision operates by reference to who holds the interest at termination, and is expressly subject to § 27-40-450 on transfer of the landlord's interest, both sections should be read together before a sale. The deposit schedule, the deposit standards disclosure and the condition records all need to come across with the property.

Step 7: Three Things § 27-40-410 Does Not Impose

No general statutory maximum. Nothing in the section limits the amount of a deposit. The figure is a lease and market question, subject to the subsection (c) disclosure where it applies. Note that the Act separately restricts certain lease provisions at § 27-40-330, so a deposit arrangement should be reviewed against the chapter as a whole rather than § 27-40-410 alone.

No separate-account or escrow requirement. The section does not require deposits to be segregated, held at a particular institution, or kept in any specified account type.

No interest-payment requirement. The section imposes none.

That is a real contrast with trust-account states such as North Carolina, whose deposit statute prescribes holding requirements alongside its return rule. South Carolina regulates the disposition and leaves the custody to you, which does not remove the accounting obligation. A deposit remains a liability from receipt until a valid disposition, and the reconciliation discipline in our guide to security deposit accounting across intake, holding and reconciliation applies regardless, as does the treatment set out in deposits on the balance sheet.

Step 8: Where a Casualty Routes Back Into the Deposit Rules

One provision outside § 27-40-410 pulls straight back into it.

Under § 27-40-650, where a dwelling unit is damaged or destroyed by fire or casualty to the extent that normal use and occupancy is substantially impaired, the tenant may vacate and terminate. Unless the casualty was due to the tenant's negligence or otherwise caused by the tenant, the landlord returns the security recoverable by the tenant.

Where the casualty was due to the tenant's negligence or caused by the tenant, the landlord may withhold the deposit or prepaid rent, but if the landlord withholds, § 27-40-650(b) expressly requires compliance with the notice requirement in § 27-40-410(a).

Section 27-40-650(b) does not create a separate deduction category. It preserves the landlord's ability to withhold for a tenant-caused casualty, but any withholding must still satisfy § 27-40-410(a)'s itemisation and timing rules. The wider repair and casualty framework is covered in our guide to South Carolina landlord repair obligations.

Common South Carolina Deposit Mistakes Property Managers Make

1. Calculating the itemisation deadline from move-out alone
Section 27-40-410(a) measures the thirty days from the later of termination of the tenancy and delivery of possession, and the tenant's demand.

2. Treating the absence of a demand as permission to hold the money
Subsection (a) still opens by requiring the security to be returned on termination, less permitted withholdings.

3. Not recording all three dates
Without them you cannot show which event controlled if lateness is disputed.

4. Sending money without an itemised written notice
Subsection (b) is triggered where the landlord fails to return prepaid rent or the deposit together with the notice required by subsection (a).

5. Forgetting prepaid rent
Subsection (b) expressly covers prepaid rent as well as the deposit.

6. Doing nothing when no forwarding address is given
The protection requires the landlord to have mailed the notice and amount due to the last known address.

7. Relying on that protection while knowing where the tenant is
It also requires the landlord to have had no notice of the tenant's whereabouts, which is broader than the absence of a written forwarding address.

8. Deducting for ordinary deterioration
Deductions must be for accrued rent or damages by reason of the tenant's noncompliance with § 27-40-510.

9. Assuming identical dollar amounts mean no disclosure duty
Subsection (c) turns on differing standards for calculating deposits, not differing amounts.

10. Producing that disclosure at move-in
The timing requirement is prior to consummation of the rental agreement.

11. Misreading the multi-unit penalty
The comparison is to the lowest deposit required of any other tenant of a comparable dwelling unit on the premises.

12. Treating the exposure as the deposit amount
Subsection (b) provides three times the amount wrongfully withheld, plus reasonable attorney's fees.

13. Assuming the deposit remedy is the only claim
Subsection (d) preserves other damages for both sides.

14. Overlooking successor liability
Subsection (e) binds the holder of the landlord's interest at the time of termination, subject to § 27-40-450.

15. Treating a tenant-caused casualty as outside the notice rules
Section 27-40-650(b) preserves the ability to withhold but requires compliance with § 27-40-410(a).

Conclusion

South Carolina's deposit rules are short, and the central deadline is more specific than most summaries suggest.

• The itemisation deadline is measured from the later of several events. Termination of the tenancy and delivery of possession, and the tenant's demand. But subsection (a) still opens by requiring the security to be returned on termination, so the timing language is not a reason to hold a tenant's money.

• Two categories of deduction, one defined by cross-reference. Accrued rent, and damages by reason of the tenant's noncompliance with § 27-40-510. The statute does not separately define normal wear and tear, so each deduction needs to be connected to a specific tenant obligation.

• One protection, with two conditions. Where the tenant leaves no forwarding address, the landlord must have had no notice of their whereabouts and have mailed the notice and amount due to the last known address.

• And one obligation is easy to miss. More than four adjoining dwelling units plus differing standards for calculating deposits means a conspicuous posting or a written statement prior to consummation of the rental agreement, and failing it puts part of the deposit beyond deduction.

For teams managing portfolios in Charleston, Columbia, Greenville or Myrtle Beach, the deposit file rests on five records: the termination date, the possession date, any demand and when it arrived, the condition evidence at both ends, and the deposit standards disclosure where subsection (c) applies. Keeping the deposit balance and every deduction tied to the tenancy through collecting rent and payments, and surfacing every approaching deadline through dashboards and reports, is what turns several separate trigger dates into a single visible one.

This blog is for informational purposes only and does not constitute legal advice. South Carolina security deposit requirements sit at S.C. Code Ann. § 27-40-410 within the Residential Landlord and Tenant Act, §§ 27-40-10 to 27-40-940, with tenant obligations at § 27-40-510, prohibited lease provisions at § 27-40-330, transfer of the landlord's interest at § 27-40-450, and the fire and casualty provision at § 27-40-650. Section 27-40-410 was enacted by 1986 Act No. 336 and amended by 1994 Act No. 498; verify the current text before relying on it. Section 27-40-120 excludes nine arrangements from the Act. Act No. 184 of 2026 added § 27-40-350 concerning protected-tenant lease termination, effective 18 May 2026, and further 2026 legislation affected Chapter 37 ejectment procedure; neither is addressed here. Deposit claims are commonly brought in Magistrates Court, whose civil jurisdictional limits are set by statute and may change; verify the current limit in § 22-3-10.

Frequently Asked Questions

Q1. Is there a security deposit limit in South Carolina?
Section 27-40-410 sets no general statutory maximum, imposes no separate-account or escrow requirement, and contains no interest-payment requirement. The chapter separately restricts certain lease provisions at § 27-40-330.

Q2. When must a South Carolina landlord provide the itemisation?
Within 30 days after termination of the tenancy and delivery of possession and demand by the tenant, whichever is later, under § 27-40-410(a). Subsection (a) separately requires the security to be returned upon termination, less permitted withholdings.

Q3. What must the landlord send?
An itemised written notice of every deduction, together with the amount due, if any. Subsection (b) is triggered where the landlord fails to return prepaid rent or the deposit together with that notice.

Q4. What if the tenant leaves no forwarding address?
The tenant is not entitled to damages under subsection (a) provided the landlord had no notice of the tenant's whereabouts and mailed the written notice and amount due to the last known address. Both conditions are required.

Q5. What can a South Carolina landlord deduct?
Accrued rent, and damages the landlord has suffered by reason of the tenant's noncompliance with § 27-40-510. Ordinary deterioration not traceable to tenant noncompliance generally cannot be withheld.

Q6. What is the multi-unit disclosure requirement?
Under § 27-40-410(c), where a landlord rents more than four adjoining dwelling units on the premises and imposes different standards for calculating deposits, the standards must be posted conspicuously or given to each prospective tenant prior to consummation of the rental agreement.

Q7. What happens if that disclosure is missed?
The difference between that tenant's deposit and the lowest deposit required of any other tenant of a comparable dwelling unit on the premises may not be withheld for damages under § 27-40-510.

Q8. What is the penalty for wrongly withholding a deposit?
Under § 27-40-410(b), the tenant may recover the property and money in an amount equal to three times the amount wrongfully withheld, plus reasonable attorney's fees.
