South Dakota Rent Increase Laws: The Landlord and Tenant Guide
No Statutory Cap · 30-Day Month-to-Month Notice · Local Rent Control Banned · Mid-Lease Lock · Retaliation Limits
South Dakota is a genuinely free-market rent state. There is no statutory cap on how much a landlord may raise the rent, and South Dakota Codified Laws section 6-1-13 goes a step further and forbids any city or county from adopting rent control at all. What the law does regulate is process: on a month-to-month tenancy, South Dakota Codified Laws section 43-32-13 requires at least 30 days’ written notice before a rent change takes effect, a fixed-term lease locks the rent until renewal, and sections 43-32-27 and 43-32-28 make a retaliatory increase unlawful. Get the timing and the notice right and, because there is no ceiling to clear, almost every South Dakota increase holds. This guide walks the whole framework end to end, in plain English, with every rule tied to a concrete action.
The practical point is that South Dakota inverts the usual landlord worry. In a capped state the hard question is how much; in South Dakota the amount is rarely the problem and the process almost always is. An increase served with too little notice, one imposed mid-term on a fixed lease with no escalation clause, or one that lands just after a tenant complained to a code office can be refused or challenged even though no dollar limit was exceeded. Because statutes and their interpretation change over time, treat every figure in this guide as a starting point and verify the current text of the South Dakota Codified Laws before you serve a notice.
Below, a detailed overview video summarizes the South Dakota framework; the sections that follow break down each piece — why there is no cap and no local rent control, the 30-day month-to-month notice rule under section 43-32-13, when you may raise rent at all, when the rent is locked, the retaliation and fair-housing limits, local practice, and a step-by-step landlord playbook — plus a South Dakota-specific FAQ.

No Rent Cap and No Rent Control
The defining feature of South Dakota rent-increase law is what is missing: there is no statutory cap on the amount of an increase. Unlike a rent-controlled state, South Dakota sets no percentage ceiling, no inflation formula, and no maximum dollar figure. A landlord may raise the rent to any amount the market will bear, provided the increase respects the lease, is delivered with the required notice, and is neither retaliatory nor discriminatory.
Local Rent Control Is Prohibited by Statute
South Dakota does not merely leave a gap for cities to fill — it closes the door. South Dakota Codified Laws section 6-1-13, titled Rent control of private residential property prohibited and on the books since 1990, states that no local governmental unit may enact, maintain, or enforce any ordinance, resolution, or other enactment that would have the effect of controlling the amount of rent charged for leasing private residential property. In plain terms, no South Dakota city or county — not Sioux Falls, not Rapid City, not Aberdeen or Brookings — can adopt a local rent cap or rent-stabilization program. This is a deliberate statewide policy choice that makes South Dakota one of the most landlord-flexible states in the country for setting rent.
The one narrow exception in section 6-1-13
The preemption is not quite absolute. Section 6-1-13 preserves the right of a local governmental unit to manage and control residential property in which the unit itself holds a property interest — for example, housing the city or county owns or operates. That carve-out is about a government acting as a property owner, not as a regulator. It does not give any South Dakota city a path to cap rents on ordinary privately owned rentals.
Why the Missing Cap Shifts the Whole Analysis
Because no number caps the increase, the legal risk in a South Dakota rent raise almost never comes from the amount. It comes from how the increase is done: the tenancy type, the notice, the timing relative to protected tenant activity, and the reason behind it. A landlord who internalizes that shift — treating South Dakota rent increases as a process-and-timing problem rather than a math problem — will get the great majority of increases to stick without incident.
No cap does not mean no rules
It is a common and costly misreading to treat “no rent control” as “anything goes.” The notice requirement in section 43-32-13, the mid-term lock during a fixed lease, and the retaliation ban in sections 43-32-27 and 43-32-28 all apply regardless of the amount. An increase that ignores those rules is unenforceable or actionable even though no dollar ceiling exists. The freedom in South Dakota is on price, not on process.
Takeaway
South Dakota has no statutory rent cap and no rent control — and section 6-1-13 bans cities and counties from adopting any. The amount is rarely the legal issue; the notice, the tenancy type, the timing, and the motive are. Freedom on price, discipline on process.
Notice: The 30-Day Month-to-Month Rule
The single procedural rule that governs most South Dakota rent increases lives in South Dakota Codified Laws section 43-32-13, titled “Modification of lease — Written notice by landlord, effect — Termination by tenant.” It applies to a month-to-month (periodic) tenancy and it works in two directions at once: it lets the landlord change the rent on notice, and it gives the tenant a short window to walk away instead.
What Section 43-32-13 Requires of the Landlord
For a lease from month to month, the landlord may modify the terms of the lease — including raising the rent — by giving written notice at least 30 days before the expiration of the month. The modification takes effect at the expiration of that month, and once the tenant continues to hold the premises after the effective date, the modified terms become part of the lease going forward. The notice must be in writing; an oral announcement, a text, or an email the tenant never agreed to accept as a delivery method does not satisfy the statute and does not start the clock.
The Tenant’s 15-Day Termination Right
Section 43-32-13 balances the landlord’s power to change the rent with a tenant escape hatch. A tenant who receives a modification notice may terminate the tenancy effective the first day of the next month by giving the landlord notice of termination within 15 days of receiving the modification notice. In practice, that means a rent increase served under this section is really an offer: the tenant can accept the new rent and stay, or reject it by giving prompt notice and moving out at the end of the month. This is the South Dakota analog to the “accept or leave” logic of a month-to-month raise, but with a specific 15-day response deadline written into the statute. For how a tenant properly ends a tenancy in response, see our guide to South Dakota lease termination laws.
| Who | What section 43-32-13 requires |
|---|---|
| Landlord raising rent (month-to-month) | Written notice at least 30 days before the expiration of the month; change takes effect at month’s end |
| Tenant who rejects the increase | May terminate effective the first day of the next month by giving notice within 15 days of receiving the modification notice |
| Method | In writing, by a provable method (certified mail, personal delivery with acknowledgment) |
What a Proper Notice Contains and How to Serve It
A defensible South Dakota rent-increase notice is in writing and states, at minimum: the tenant’s name and the property address, the current rent, the new rent, and the effective date — with enough lead time to satisfy the 30-day requirement measured to the expiration of the month. Serve it by a provable method: certified mail with return receipt, personal delivery with a signed acknowledgment, or another method your lease and any local rules allow. Keep a copy of both the notice and the proof of delivery. A clean paper trail is the difference between an increase that is obviously compliant and one a tenant can plausibly dispute.
The lease can require more, never less
Section 43-32-13 sets a floor, not a ceiling. If the lease itself promises a longer notice period, or specifies a particular delivery method, the lease term controls when it is more protective of the tenant. Many landlords voluntarily give 60 days as a courtesy; that is fine and often smart for retention, but the statutory minimum for a month-to-month change is the at-least-30-days-before-month’s-end rule. When in doubt, give more notice, not less.
Takeaway
On a month-to-month tenancy, section 43-32-13 requires written notice at least 30 days before the expiration of the month, and it gives the tenant 15 days to terminate instead of accepting. Put it in writing, serve it by a provable method, and keep proof of delivery.
When You Can Raise the Rent at All
The notice rule only matters once you actually have the right to raise the rent. That right depends entirely on the tenancy type.
During a Fixed-Term Lease: Generally Locked
While a fixed-term lease is running, the rent is set at the agreed amount for the whole term. You cannot raise it mid-term unless the lease itself contains an explicit escalation clause that permits the change. The section 43-32-13 modification process applies to periodic (month-to-month) tenancies, not to a fixed term that has not yet ended. Absent an escalation clause, the tenant is entitled to the agreed rent through the last day of the term.
At Renewal or on a Month-to-Month Tenancy
The two ordinary windows to raise rent are at lease renewal, when a new term begins and the parties agree on a new rent, and during a month-to-month tenancy, where the landlord may change the rent going forward by serving the section 43-32-13 notice. On a month-to-month, the increase takes effect only at the expiration of the month for which proper notice was given; the tenant can accept the new rent and stay, or use the 15-day termination right and move out.
A mid-term increase without authority is unenforceable
Trying to raise rent partway through a fixed-term lease with no escalation clause does not quietly work — the increase is unenforceable, and a tenant who keeps paying the original rent is in the right for the rest of the term. Do not treat a tenant’s silence as agreement. Wait for renewal, or convert to a lawful month-to-month process, before adjusting the rent.
Takeaway
You may raise rent at renewal or on a month-to-month tenancy with proper notice, but never mid-term on a fixed lease unless the lease expressly allows it. The tenancy type decides whether you even have the authority; the notice rule decides how.
When the Rent Is Locked and How Often You Can Raise It
South Dakota’s freedom on the amount comes with a few natural brakes on timing that landlords should plan around.
No Statutory Frequency Limit
South Dakota does not cap how often rent may be raised. On a month-to-month tenancy, each increase simply needs its own section 43-32-13 notice, given at least 30 days before the expiration of the month it is meant to change. On a fixed-term lease, the practical opportunity to raise rent is at renewal, when a new term is negotiated. There is no annual limit and no “once per lease” rule in the statute.
Fixed Term Locks the Rent Until It Ends
The clearest lock in South Dakota law is the fixed-term lease itself. For its entire duration, the agreed rent is the rent, unless an escalation clause says otherwise. That lock protects the tenant and, just as importantly, protects the landlord’s expectations too: it is the reason a well-drafted lease with a clear renewal-and-increase mechanism is worth more than an informal arrangement.
Frequent or steep increases carry practical risk
The absence of a frequency cap is not an invitation to raise rent repeatedly. Each increase resets the 15-day termination clock for the tenant, and a pattern of sharp or rapid increases raises turnover and, if any of them lands soon after protected tenant activity, invites a retaliation challenge under sections 43-32-27 and 43-32-28. The disciplined approach is a predictable schedule — typically a single renewal-time adjustment — supported by documented market comparables.
Takeaway
There is no frequency cap in South Dakota, but a fixed-term lease locks the rent until it ends, and each month-to-month increase needs its own 30-day notice. Predictable, renewal-timed increases stick better and draw fewer challenges than rapid ones.
Retaliation and Fair Housing Limits
Two limits apply on top of the notice rule, and because South Dakota has no cap to clear, these are where most genuine legal exposure lives. An increase that is procedurally perfect can still be unlawful if it trips either one.
The Statutory Retaliation Ban
Unlike some free-market states, South Dakota does have an explicit anti-retaliation statute. South Dakota Codified Laws sections 43-32-27 and 43-32-28 prohibit a landlord from retaliating against a tenant who exercises a legal right. The prohibited retaliatory acts are increasing rent above fair market value, decreasing electric, gas, water, or sewer services, or giving a notice to vacate that is not based on a lease breach. The protected tenant activities are: making a good-faith complaint to a governmental agency charged with enforcing a building or housing code about a violation materially affecting health and safety, complaining to the landlord about such a condition, and organizing or joining a tenants’ union or a similar organization.
The teeth of the statute are in its presumption and its remedies. If the landlord takes one of those actions within 180 days after the tenant’s protected activity, retaliation is presumed, and the burden shifts to the landlord to show a legitimate, non-retaliatory business reason. A tenant who establishes retaliation may recover up to two months’ rent, the return of any security deposit, and reasonable attorney fees (the statute sets no dollar cap on the fee award). Because one of the prohibited retaliatory acts is bringing an action for possession, the retaliation ban ties directly into the eviction rules; for how a lawful, non-retaliatory removal must be handled, see our guide to South Dakota eviction notice laws. There is a matching exception: giving a notice to move (or not renewing a written lease at its end) more than 180 days after the protected activity is not treated as retaliatory under the statute.
The 180-day window is the number to watch
Timing is everything under sections 43-32-27 and 43-32-28. An increase served a week after a tenant reports a code violation looks retaliatory even if the number is reasonable; the same increase, on the ordinary renewal schedule with documented comparables, is routine. Before you serve, ask whether the tenant has engaged in any protected activity in the last 180 days. If so, wait for the ordinary schedule and paper the legitimate business reason for the increase.
Fair Housing: No Cap Excuses Discrimination
A rent increase cannot be used to discriminate against a protected class. The federal Fair Housing Act prohibits discrimination based on race, color, religion, national origin, sex, familial status, and disability. The South Dakota Human Relations Act (South Dakota Codified Laws Title 20, Chapter 13) mirrors those categories in housing, protecting against discrimination based on race, color, creed, religion, sex, ancestry, disability, familial status, and national origin. You cannot set or raise rent to push out, or to refuse to accommodate, a tenant because of any of those characteristics.
South Dakota does not add source-of-income protection
Unlike some states, South Dakota does not include “source of income” among its protected classes, so state law does not, on its own, bar a landlord from declining a housing voucher such as Section 8 or from treating voucher income differently. That said, a rent decision that uses a voucher as a pretext for another protected trait, or that runs afoul of a program’s own rules, can still create liability. And a local ordinance or program agreement may impose obligations the state statute does not, so confirm the specific situation.
Consistency is your best defense
Increases applied evenly across comparable units on a regular schedule are far easier to defend than a one-off increase aimed at a single tenant. A selectively applied hike, or one that lands right after a complaint, invites both a retaliation presumption and a fair-housing claim — even in a state with no cap on the amount.
Takeaway
Even with no cap, an increase is unlawful if it is retaliatory under sections 43-32-27 and 43-32-28 (within 180 days of a complaint, a report to an agency, or tenant organizing) or discriminatory under the federal Fair Housing Act and the South Dakota Human Relations Act. Apply increases consistently, on schedule, with a documented business reason.
South Dakota Versus a Rent-Control State
To see how much freedom South Dakota gives, it helps to set it beside a heavily regulated state. California caps the annual increase on covered housing at 5 percent plus regional inflation with a hard ceiling, stacks dozens of local rent-control ordinances on top, and requires 30 or 90 days’ notice depending on how large the increase is. South Dakota has none of that machinery.
| Issue | South Dakota | California (for contrast) |
|---|---|---|
| Statutory cap | None | 5 percent plus regional inflation, 10 percent maximum on covered housing |
| Local rent control | Banned by SDCL 6-1-13 | Permitted; many cities run stabilization programs |
| Notice to raise rent | At least 30 days (month-to-month), SDCL 43-32-13 | 30 days (10 percent or less) or 90 days (more), Civil Code 827 |
| Frequency limit | None | Effectively capped by the annual limit |
| Retaliation ban | Yes, SDCL 43-32-27 and 43-32-28 (180-day presumption) | Yes, statutory presumption |
The contrast is the whole point: a South Dakota landlord’s compliance work is almost entirely about notice, timing, and motive, because the amount is unregulated. A California landlord must clear a numeric cap before any of that even matters. If you own rentals in both kinds of states, do not carry a capped-state instinct into South Dakota — and never carry a South Dakota “no cap” instinct into a state that has one.
Takeaway
South Dakota and a rent-control state sit at opposite ends of the spectrum. South Dakota has no cap and bans local rent control; the only real gates are the 30-day notice, the fixed-term lock, and the retaliation ban. Never carry one state’s rent-increase habits into the other.
The South Dakota Landlord Playbook
Put the whole framework into a repeatable sequence and a rent increase becomes routine instead of risky. Follow these steps every time.
Confirm the tenancy type
Determine whether the tenant is on a fixed-term lease (rent locked until renewal unless an escalation clause allows a mid-term change) or month-to-month (adjustable on section 43-32-13 notice). The tenancy type decides whether you can raise rent now at all.
Set a market-supported number
There is no cap, so the number is a business decision, not a legal one. Pull comparable rents and document your cost drivers. A defensible, market-aligned figure reduces turnover and blunts any claim that the increase was a pretext for retaliation.
Check the 180-day retaliation window
Before you serve, confirm the tenant has not engaged in protected activity — a complaint to an agency, a complaint to you about a breach of duties, or joining a tenants’ union — within the last 180 days. If they have, wait for the ordinary schedule and document your business reason.
Serve the section 43-32-13 notice
For a month-to-month, give written notice at least 30 days before the expiration of the month, stating current rent, new rent, and effective date. Deliver it by a provable method — certified mail with return receipt or personal delivery with a signed acknowledgment.
Document everything
Keep a copy of the notice, the proof of delivery, the comparables you relied on, and a note of the market and cost reasons behind the increase. Consistent, documented increases are the ones that hold up if a tenant ever disputes.
Need the notice itself?
A ready-to-fill notice keeps the required fields in place. See our free South Dakota rent increase notice form, and the South Dakota lease agreement form if you need an escalation clause or a fresh renewal term. Always tailor the numbers to your unit and verify current law.
Common Scenarios, Quickly Answered
✓ Usually Defensible
- Renewal increase. A 60-day written notice before a new term begins, at a market-supported figure — no cap to clear.
- Month-to-month raise with proper notice. A written notice given at least 30 days before month’s end under section 43-32-13.
- Market reset at turnover. Setting a new market rent for a brand-new tenant after the prior one moves out.
- Consistent annual adjustment. The same schedule applied across comparable units with documented comparables.
✕ Likely Unlawful
- Mid-term hike, no clause. Raising rent during a fixed lease with no escalation clause — unenforceable for the term.
- Under-noticed increase. A month-to-month raise served with less than the 30-day, before-month’s-end notice.
- Post-complaint increase. A raise within 180 days of a code complaint or tenant organizing — presumed retaliation.
- Verbal or discriminatory. A spoken increase with no record, or one aimed at a fair-housing protected class.
Rent Increases Go Smoother With the Right Tenant
The tenants who fight every lawful increase are often the ones who show red flags on screening. Comprehensive credit, income, and eviction-history reports catch the mismatch before you ever sign a lease.
Frequently Asked Questions
How much can a landlord raise the rent in South Dakota?
There is no statutory ceiling. South Dakota does not cap rent-increase amounts, and no statewide percentage limit applies. A landlord may raise the rent by any amount as long as the increase respects the lease, is delivered with the proper written notice, and is not retaliatory or discriminatory. Local governments cannot fill the gap either, because South Dakota Codified Laws section 6-1-13 forbids any city or county from enacting rent control. In South Dakota the legal question is almost never how much, but whether the increase followed the correct process and timing.
How much notice must a South Dakota landlord give before raising rent?
For a month-to-month tenancy, South Dakota Codified Laws section 43-32-13 lets the landlord modify the lease, including the rent, by giving written notice at least 30 days before the expiration of the month, with the change taking effect at the end of that month. The same section gives the tenant a right to respond: a tenant who receives a modification notice may terminate the tenancy effective the first day of the next month by giving notice of termination within 15 days of receiving the landlord’s notice. Put the increase in writing, serve it by a provable method, and keep proof.
Is there rent control anywhere in South Dakota?
No. South Dakota has no statewide rent control, and South Dakota Codified Laws section 6-1-13, titled Rent control of private residential property prohibited, bars every local governmental unit from enacting, maintaining, or enforcing any ordinance that controls the amount of rent charged for private residential property. So no South Dakota city, including Sioux Falls or Rapid City, can adopt a local rent cap. The one narrow carve-out is that a local government may still manage rent on residential property in which it holds a property interest.
Can a landlord raise the rent in the middle of a lease in South Dakota?
Generally no. During a fixed-term lease the rent is locked at the agreed amount for the whole term unless the lease itself contains an escalation clause that expressly permits a mid-term increase. The section 43-32-13 month-to-month modification process applies to periodic tenancies, not to a fixed term still running. A landlord may raise rent at renewal, when a new term begins, or on a month-to-month tenancy with proper 30-day written notice.
Does South Dakota have a limit on how often rent can be raised?
There is no statutory frequency limit in South Dakota. On a month-to-month tenancy a landlord may raise rent as often as the section 43-32-13 notice rule allows, meaning each increase needs its own written notice given at least 30 days before the end of the month. On a fixed-term lease the ordinary opportunity to raise rent is at renewal. Even without a frequency cap, repeated or steep increases invite tenant turnover and can draw a retaliation challenge if the timing lines up with protected activity.
Can a rent increase be illegal in South Dakota even though there is no cap?
Yes. The absence of a cap does not make every increase lawful. Under South Dakota Codified Laws sections 43-32-27 and 43-32-28, a rent increase is unlawful if it is retaliatory, and under the federal Fair Housing Act and the South Dakota Human Relations Act it is unlawful if it discriminates against a protected class. An increase served with less than the required notice, or one raised mid-term with no lease authority, is also unenforceable for that period. No cap governs the amount, but process and motive still control legality.
Does South Dakota law protect tenants from a retaliatory rent increase?
Yes. South Dakota Codified Laws sections 43-32-27 and 43-32-28 prohibit retaliation. If a landlord raises rent above fair market value, decreases services, or brings an action for possession within 180 days after a tenant makes a good-faith health-and-safety code complaint to a governmental agency, complains to the landlord about such a condition, or joins a tenants’ union or similar organization, retaliation is presumed. A tenant who proves retaliation may recover up to two months’ rent, the return of any security deposit, and reasonable attorney fees. A landlord can rebut the presumption with a legitimate, documented business reason.
Can I set rent at market rate for a new South Dakota tenant?
Yes. Because South Dakota has no rent control, there is no restriction on the starting rent for a brand-new tenancy. When a prior tenant moves out, the landlord may set the opening rent for the next tenant at any lawful market amount. The notice rule in section 43-32-13 governs a change to an existing tenancy, not the initial rent in a new lease, which is set by agreement when the tenant signs.
What is the safest way for a South Dakota landlord to raise rent?
Confirm the tenancy type, because a fixed-term lease locks the rent until renewal while a month-to-month can be changed on notice. Serve a clear written notice at least 30 days before the end of the month under section 43-32-13, by a provable method such as certified mail or personal delivery with a signed acknowledgment. Avoid raising rent within 180 days of protected tenant activity, apply increases consistently, and keep a copy of the notice and proof of delivery. Document a legitimate market or cost reason, and verify current law before you serve.
How does South Dakota compare with a rent-control state like California?
They sit at opposite ends of the spectrum. California caps annual increases on covered housing at 5 percent plus regional inflation with a hard ceiling, layers local rent-control ordinances on top, and requires 30 or 90 days’ notice depending on the size of the increase. South Dakota has no cap at all, bans local rent control under section 6-1-13, and requires only the single 30-day month-to-month notice under section 43-32-13. A South Dakota landlord has far more freedom on the amount, so the compliance work shifts almost entirely to notice, timing, and avoiding retaliation.
What should a South Dakota tenant do about a rent increase they think is unlawful?
Do not withhold rent, because nonpayment can trigger eviction regardless of the dispute. Instead, keep the written notice and note the date and method of delivery, and check whether it gave the full 30 days and whether the timing follows protected activity within the 180-day retaliation window under sections 43-32-27 and 43-32-28. Pay under protest if needed, raise the notice, lease, or retaliation defense, or give proper notice to vacate. For a specific situation, consult a licensed South Dakota attorney before acting.
