Mold in a South Carolina rental: who handles it, tenant or landlord?

South Carolina's starting point

South Carolina has no mold-specific rental statute — no required mold disclosure, no state exposure limits. What it has is the Residential Landlord and Tenant Act, and one section does most of the work: landlords must comply with building and housing codes materially affecting health and safety, make repairs needed to keep the place fit and habitable, and keep plumbing, HVAC, and other systems in reasonably good working order (S.C. Code § 27-40-440). Mold is almost always the symptom of something on that list — a roof leak, failed flashing, sweating ductwork, a wet crawlspace — so mold caused by the building's condition points at the landlord's repair duty.

Where the tenant's side comes in

Tenants control the moisture habits of the home: running bath fans, reporting leaks promptly, not drying laundry indoors, keeping the AC actually running through a Lowcountry summer instead of shutting the unit up for a month. Mold traceable to those conditions gets murkier, and a landlord may fairly argue it isn't a building failure. Most real disputes land somewhere in the middle — which is why the paper trail below matters more than the argument.

The process that actually gets it fixed

• Report it in writing — text or email counts; you want a timestamp — with photos, the week you notice it.
• Name the suspected source if you can see one: "the bathroom ceiling stain spreads after rain" is actionable; "there's mold" is not.
• Give a reasonable window for a response, and save every reply.
• If nothing happens, South Carolina's Act gives tenants a formal lever: for a material problem affecting health and safety, a tenant may deliver written notice that the lease terminates on a date at least 14 days out unless the problem is fixed (S.C. Code § 27-40-610). It's a serious step with real requirements — get advice from SC Legal Services or an attorney before using it.
• Skip improvised remedies like withholding rent. South Carolina law doesn't provide the broad repair-and-deduct rights some states have, and getting it wrong can turn a repair dispute into an eviction case.

Insurance, briefly

The landlord's policy generally covers the building; a tenant's renters policy generally covers belongings — and both usually limit mold coverage. Mold that followed a sudden covered event, like a burst pipe reported promptly, is far more claimable than mold from slow neglect. Same rule as everywhere else in this climate: sudden and documented beats gradual and ignored.

Where a remediation company fits

We work tri-county rentals regularly — usually hired by the owner or property manager, often at a tenant's urging. Beyond the removal itself, the useful thing we add is a written moisture-source finding with photos and readings: an independent statement of what's feeding the growth, which settles most "whose fault is this" conversations faster than any argument.
