How much can you raise it in South Dakota?
There is no statutory ceiling. No cap. South Dakota has an explicit modification-notice provision for month-to-month leases.
Only four US jurisdictions cap the size of an increase - California, Oregon, Washington and the District of Columbia. South Dakota is not one of them, so the amount is a business decision, not a legal one. The usual constraint is practical: a tenant who leaves over an increase costs you a turnover, and a turnover costs more than the increase was worth.
Can you raise rent mid-lease in South Dakota?
Not unless the lease says so. A fixed-term lease fixes the rent for its term, whatever the statute does or does not require about notice. An increase belongs at renewal, or on a month-to-month tenancy after proper notice.
Serving the notice so it holds up
Most rent increases that fall apart fall apart on the date, not the amount: the notice went out too late, or nobody can prove when it went out. Count the days from delivery, not from the day you wrote it, and keep the proof.
LandlordPro generates the notice against the state's rule, dates it, records when it was sent, and carries the new rent onto the rent roll on the right day so the ledger and the notice agree.
