South Dakota Mobile Home Park Rent Control: 2026 Guide

Is mobile home lot rent controlled in South Dakota?

No. South Dakota does not regulate mobile home lot rent. There is no statewide rent cap, no limit on how much or how often you can raise lot rent, and no percentage ceiling anywhere in state law.

There is also no separate mobile home park act. Lot tenancies fall under the general chapter for leasing real property, SDCL Chapter 43-32 — the same chapter that covers ordinary residential leases. Only two provisions in it speak to mobile homes specifically: a 90-day notice before a home can be displaced for redevelopment (§43-32-31) and a retaliation rule that names mobile home community owners (§43-32-27). Neither is a rent cap.

Bottom line for operators: you set lot rent by the lease and by market, subject only to notice requirements and to the anti-retaliation limits below.

No rent cap and no percentage limit

Nothing in SDCL Chapter 43-32 — or elsewhere in South Dakota law — caps the amount of a rent increase or ties it to a maximum percentage or an inflation index. The state simply does not do rent control.

The only rent-related constraint outside of notice is anti-retaliation. Under §43-32-27, raising rent 'above fair market value' can be actionable, but only when it follows a protected tenant act — a good-faith complaint to a code agency, a written repair notice under §43-32-9, or the tenant organizing or joining a tenant union. That is a retaliation limit, not a general cap, and it is defensible if the notice comes more than 180 days after the protected event.

So absent a retaliation trigger, there is no legal ceiling on a South Dakota lot rent increase.

How increases work: the 30-day notice under Chapter 43-32

South Dakota has no mobile-home-specific rent-increase statute, so a month-to-month lot rent increase runs on the general modification rule, SDCL §43-32-13. The landlord may modify the lease terms — the statute expressly lists 'terms, rent, and conditions' — by giving written notice at least 30 days before the end of the month. The new rent takes effect the following month if the tenant stays.

The tenant's only built-in response is a short exit right: under the same section, the tenant may terminate effective the first of the next month by giving notice within 15 days of receiving your modification notice.

If a tenant is on a fixed-term lease, the rent is whatever that lease sets until it expires — you cannot raise it mid-term unless the lease itself allows it. The 30-day modification mechanic is for month-to-month (or holdover) tenancies. There is no separate mobile-home 'lot rent' statute layering extra notice on top.

The 90-day redevelopment notice and local rules

The one place South Dakota gives lot tenants extra time is redevelopment. SDCL §43-32-31 requires at least 90 days' notice to vacate and remove the home when the land is being developed for an alternate use. This is about displacing the home for a change of use — it is not a rent rule and does not limit rent increases. It also does not apply when your notice is based on a lease breach.

Do not confuse this 90-day redevelopment notice with a rent-increase notice; a rent increase runs on the 30-day §43-32-13 track, not this one.

Locally, there is nothing to worry about: SDCL §6-1-13 preempts the field. No South Dakota city or county may enact, maintain, or enforce any ordinance controlling rent on private residential property. There are no local rent-control or rent-stabilization ordinances anywhere in the state, and none can be created.

Rent-increase rules at a glance in South Dakota

• Statewide cap
  None. No limit on the amount or frequency of lot rent increases; no percentage ceiling (SDCL Ch. 43-32 contains no cap).
• Separate MHP act
  None. Mobile home lot tenancies are governed by the general Lease of Real Property chapter, SDCL Ch. 43-32.
• Increase notice (month-to-month)
  At least 30 days' written notice before the end of the month to modify rent under §43-32-13; increase takes effect the next month.
• Tenant exit right
  Tenant may terminate effective the first of the next month by giving notice within 15 days of receiving the modification notice (§43-32-13).
• Fixed-term leases
  Rent is locked at the lease amount until the term ends; no mid-term increase unless the lease itself permits it.
• 90-day redevelopment notice
  §43-32-31 requires at least 90 days' notice to vacate and remove the home when land is developed for an alternate use — not a rent rule; not applicable to lease-breach notices.
• Retaliation limit
  §43-32-27 makes raising rent above fair market value actionable if it follows a protected tenant act (code complaint, §43-32-9 repair notice, or joining a tenant union).
• Local rent control
  Prohibited. SDCL §6-1-13 bars any city or county from enacting rent control on private residential property.

Operator best practices in South Dakota

• Put rent and increases in the written lease
  Because Chapter 43-32 offers no lot-rent-specific framework, your lease is the controlling document. State the rent, the term, and how and when increases can occur.
• Use the 30-day modification notice correctly
  For month-to-month tenants, deliver written notice at least 30 days before month-end under §43-32-13, and expect the tenant may exercise the 15-day termination right.
• Never raise rent as retaliation
  Avoid rent increases above market that follow a tenant's code complaint, repair request, or tenant-union activity — §43-32-27 makes that actionable for mobile home community owners.
• Give the full 90 days for redevelopment
  If you are converting land to another use, provide at least 90 days' notice to vacate and remove homes under §43-32-31, and document it as redevelopment, not a lease breach.
• Don't wait on local rules
  There are no local rent ordinances to comply with — §6-1-13 preempts them — but confirm nothing changes if you operate across state lines.
• Build a relationship with a South Dakota MHP attorney
  Because protections are thin and driven by contract, have local counsel review your lease templates, notice forms, and any redevelopment or eviction sequence before you rely on them.
