South Carolina sets no cap on security deposits but requires landlords to return the deposit with a written itemization of any deductions within 30 days after the latest of three events: the tenancy ending, the tenant delivering possession, and the tenant demanding the money back.

Cited to SC Code 27-40-410 (a)-(e) and 1 more South Carolina statute · Verified July 9, 2026

A landlord who fails to return the deposit with that notice owes the tenant three times the amount wrongfully withheld plus reasonable attorney's fees — with no bad-faith requirement in the statute. Tenants have a matching duty: provide a forwarding address in writing, or forfeit the damages remedy if the landlord mails the refund to the last known address. One rule unique to larger properties: a landlord renting more than four adjoining units who uses different deposit standards for different tenants must post or hand every prospective tenant a statement of how deposits are calculated — otherwise the difference between that tenant's deposit and the lowest deposit charged for a comparable unit is immune from damage deductions. There is no escrow, separate-account, or interest requirement.

South Carolina security deposits at a glance

Maximum deposit	No statutory cap
Return deadline	30 days
Deadline conditions	The clock starts on the latest of three events: termination of the tenancy, delivery of possession, and demand by the tenant. SC 27-40-410(a) says 'within thirty days after termination of the tenancy and delivery of possession and demand by the tenant, whichever is later.' The tenant-demand element is part of the statutory text and routinely omitted by secondary sources, which start the clock at move-out or key return. The tenant must provide a forwarding or new address in writing; a tenant who fails to do so loses the right to damages under subsection (a) if the landlord (1) had no notice of the tenant's whereabouts and (2) mailed the written notice and any amount due to the tenant's last known address. Exception since May 18, 2026: on a protected tenant's early lease termination under the domestic-violence statute (SC Code 27-40-350, Act No. 184 of 2026), deposits are not required to be returned until the end of the lease term — see the notes.
Itemization required	Yes
Itemization rules	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 the 30-day window (27-40-410(a)). Deductions are limited to accrued rent and damages the landlord has suffered by reason of the tenant's noncompliance with 27-40-510 (the tenant's maintenance obligations).
Separate account required	No
Interest owed to tenant	No
Account & interest rules	Chapter 40 of the South Carolina Code contains no escrow, trust-account, or interest requirement for security deposits. Fifty-state charts that import other states' escrow or interest rules into South Carolina are wrong.
Pet deposits	No pet-deposit statute exists. A pet deposit is part of the 'security/rental deposit' scheme of 27-40-410 — same 30-day return, itemization, and 3x-penalty rules; no separate cap or treatment.
Non-refundable fees allowed	Not addressed by statute
Penalty for violation	A landlord who fails to return prepaid rent or the security deposit with the required written notice owes the tenant three times the amount wrongfully withheld plus reasonable attorney's fees (27-40-410(b)). The tenant recovers the property and money 'in an amount equal to three times the amount wrongfully withheld and reasonable attorney's fees.' The statutory text contains no bad-faith element and is a flat treble measure on the amount wrongfully withheld — sources that say South Carolina has no deposit penalty, or that soften it to 'up to 3x if the landlord acts in bad faith,' are both misreading the section. The forwarding-address failure described in subsection (a) is the one statutory escape hatch.
Tenant forwarding-address duty	Affirmative statutory duty — unusual among states: 'The tenant shall provide the landlord in writing with a forwarding address or new address' (27-40-410(a)). Failure forfeits subsection (a) damages if the landlord had no notice of the tenant's whereabouts and mailed the notice and refund to the last known address.

Notes and caveats

No cap of any kind — silence, not zero — Chapter 40 contains no deposit cap anywhere in its text. The maximum-deposit answer is left empty because there is no statutory ceiling to report, not because the ceiling is zero.
The 30-day clock has three triggers, and tenant demand is one — 27-40-410(a) runs 30 days from the latest of three events: termination of the tenancy, delivery of possession, and demand by the tenant. Nearly every secondary source misstates this as 30 days after move-out or key return.
Domestic-violence early termination pauses the return clock — Act No. 184 of 2026 (H. 3569, approved May 18, 2026, in force on approval) added SC Code 27-40-350: when a protected tenant ends the lease early after a qualifying domestic-violence incident, 'no security deposits will be required to be returned until the end of the lease if such is due to be returned.' For that termination route only, the 30-day return clock does not start until the lease term itself ends. Official code pages lag this addition; the enacted text is on the Legislature's page for H. 3569.
The 3x penalty has no bad-faith element — 27-40-410(b) is a flat treble measure on the amount wrongfully withheld. Sources that soften it to 'up to 3x if the landlord acts in bad faith' are misreading the section.
Sources saying South Carolina has no deposit penalty are wrong — Subsection (b) of 27-40-410 is explicit. The claim that South Carolina imposes no penalty for a wrongfully withheld deposit is false.
The 'estimated in 30 days, final in 60' rule is North Carolina's — Some landlord guides describe an estimated accounting within 30 days and a final one within 60. That is North Carolina's G.S. 42-52 procedure imported into South Carolina by mistake — no such provision exists in chapter 40.
The more-than-four-units posting rule is narrower than it looks — Under 27-40-410(c) a landlord renting more than four adjoining units who uses different deposit standards for different tenants must post or hand every prospective tenant a statement of how deposits are calculated. It applies only where the landlord actually imposes different deposit standards on the premises, and its sanction is deduction immunity for the differential, not a fine.
Nonrefundable fees: the statute simply does not say — Chapter 40 neither authorizes nor prohibits nonrefundable fees, and 27-40-210(11) excludes 'security deposits or other charges' from rent. That makes them a lease-drafting question rather than a statutory one, which is why the field is left empty instead of answered yes or no.
