South Carolina Rent Increase 2026: Lease Rules, 30-Day Termination Rule & Pending S. 825
South Carolina's current Residential Landlord and Tenant Act does not set one general statewide percentage formula for ordinary private rent increases. Learn why the 30-day month-to-month rule is a termination rule, how lease terms and retaliation protections matter, and why pending S. 825's proposed 30/60-day rent-increase notice schedule is not current law.
The short answer
South Carolina's current codified Residential Landlord and Tenant Act, reviewed September 19, 2026, does not set one general statewide numerical percentage ceiling or one standalone statewide rent-increase notice period for every ordinary private residential tenancy. Section 27-40-310 allows a landlord and tenant to include lawful terms such as rent and the term of the agreement in the rental agreement, so the lease structure and tenancy type matter before a rent change is treated as effective.
A widely cited 30-day number appears in § 27-40-770, but that section governs termination of a month-to-month tenancy. It is not a universal 30-day rent-increase notice rule. A landlord or tenant may terminate a month-to-month tenancy by written notice at least 30 days before the stated termination date; the same section uses seven days for a week-to-week tenancy. Max Rental Tools therefore keeps ordinary South Carolina automated rent-increase timing review-gated rather than converting termination timing into a rent-change deadline.
Start with the rental agreement and tenancy type
Section 27-40-310(a) says the parties may include lawful terms and conditions in the rental agreement, including rent and the term of the agreement. Subsection (d) says that when the agreement does not fix a definite term, the tenancy is week-to-week for a roomer who pays weekly rent and otherwise month-to-month. Those classifications can affect how the parties should analyze a proposed change, renewal or termination.
For a fixed-term lease, review the agreed rent, the lease term, any renewal or extension language, and any clause that addresses changes. Do not assume that a periodic-tenancy termination statute automatically authorizes a midterm rent increase. For a month-to-month or qualifying week-to-week tenancy, identify the actual periodic structure first and then verify the current law and agreement before choosing an effective date.
Why South Carolina's 30-day rule is not a universal rent-increase deadline
Section 27-40-770 is titled 'Periodic tenancy; holdover remedies.' It gives either the landlord or tenant at least seven days' written notice to terminate a week-to-week tenancy and at least 30 days' written notice to terminate a month-to-month tenancy. The statutory text is about termination, not a universal rent-increase notice deadline.
That distinction matters for renters, landlords and property managers searching for a simple '30-day rule.' A termination notice, a lease-renewal offer and a rent-increase notice can have different legal functions. Max Rental Tools does not silently turn § 27-40-770 into a statewide 30-day rent-increase rule, and ordinary automated notice timing remains review-gated for South Carolina rent-change calculations.
Retaliatory rent increases have a separate statutory safeguard
Section 27-40-910 addresses retaliatory conduct. Except as the section provides, a landlord may not retaliate by increasing rent to an amount in excess of fair-market value, decreasing essential services or bringing an action for possession after specified protected tenant complaints to a governmental housing-code agency or to the landlord about a violation of the chapter.
The statute also contains exceptions and remedy provisions, so it should not be reduced to a blanket statement that every increase after a complaint is automatically unlawful. The timing, protected activity, fair-market-value issue and statutory exceptions all require fact-specific review.
Pending S. 825 proposes 30-day and 60-day rent-increase notice periods — but it is not current law
South Carolina S. 825, the Family Protection Act, was introduced in the Senate on January 15, 2026 and referred to the Senate Finance Committee. The official bill page still lists it as residing in the Senate. It has not been enacted into the current Code of Laws, so its proposed rent-increase provisions must not be used as current calculator or document logic.
S. 825 would add § 27-40-795. As introduced, it would require at least 30 days' written notice before a week-to-week or month-to-month rent increase of less than 10% and at least 60 days for an increase of 10% or more, with additional fixed-term and delivery provisions. Those 30/60-day figures are proposal-only as of September 19, 2026. They are included here to explain why current search results or discussions may mention them, not to present them as enacted South Carolina law.
Not every housing arrangement falls under Chapter 40
Section 27-40-120 excludes several arrangements from the Residential Landlord and Tenant Act. One important example is residence at an institution when the residence is incidental to medical, geriatric, educational, counseling, religious or similar services. Transient hotel or motel occupancy and certain other listed arrangements are also outside the chapter.
That coverage rule can matter for students, interns, clinical-rotation participants, medical residents, traveling professionals and other temporary occupants. Their job title or school status does not decide coverage by itself. The actual housing arrangement, contract, property use and statutory classification must be checked before an ordinary apartment rule is applied.
A practical South Carolina rent-change checklist
Before sending or responding to a rent-change notice, identify whether the arrangement is a fixed term, month-to-month, week-to-week room rental or another classification; review the lease's rent and renewal language; confirm that Chapter 40 actually governs the arrangement; check whether a subsidized-housing or other program rule adds requirements; and verify that no retaliation issue is being overlooked.
Use the South Carolina state guide and rent-increase calculator as a screening step, then use the Rent Increase Notice or Lease Renewal Notice only after the applicable timing has been verified. The Month-to-Month Rental Agreement and Rent Ledger can help document the tenancy structure and payment history.

Common questions
Is there a statewide South Carolina rent cap in 2026?
The current codified Residential Landlord and Tenant Act reviewed September 19, 2026 does not set one general statewide numerical percentage ceiling for ordinary private residential rent increases. Lease terms, retaliation protections, housing-program rules and coverage can still affect a particular increase.
Does South Carolina require 30 days' notice for every rent increase?
Do not treat 30 days as a universal statewide rent-increase deadline. Section 27-40-770 uses 30 days for termination of a month-to-month tenancy, not as a standalone rent-increase notice rule.
What does South Carolina law say about month-to-month tenancy?
Section 27-40-310(d) generally makes a tenancy month-to-month when the rental agreement does not fix a definite term, except that a roomer who pays weekly rent is week-to-week. The lease and full statutory context should still be reviewed before a rent change.
Can a South Carolina landlord retaliate by raising rent after a tenant complains?
Section 27-40-910 restricts specified retaliatory conduct, including increasing rent above fair-market value after certain protected complaints, subject to the section's exceptions and remedies. A particular situation requires fact-specific review.
Did South Carolina pass a 30-day or 60-day rent-increase notice law in S. 825?
No enacted rule from S. 825 is being used here. As of September 19, 2026, the official General Assembly page shows S. 825 as introduced in the Senate and referred to Finance. Its proposed 30-day and 60-day rent-increase notice schedule is proposal-only and is excluded from Max Rental Tools calculator and document logic.
Does the South Carolina Residential Landlord and Tenant Act cover student or medical housing?
Not automatically. Section 27-40-120 excludes residence at an institution when occupancy is incidental to specified services including medical and educational services, among other exclusions. Coverage depends on the actual arrangement rather than the occupant's label alone.
Can Max Rental Tools automatically choose a South Carolina rent-increase notice date?
Not as an authoritative universal answer. Ordinary South Carolina rent-increase timing remains review-gated because current enacted law does not provide one standalone notice period for every tenancy. Confirm the lease, tenancy type, coverage and any program rules before relying on an effective date.
