What late fees can a landlord charge in South Dakota?

Verified July 11, 2026 All South Dakota topics →

South Dakota has no statute capping residential late fees and no statutorily mandated grace period — late charges are purely a matter of the lease agreement, bounded only by ordinary contract-law limits on penalty clauses.

The state's residential landlord-tenant chapter (SDCL ch. 43-32) never mentions late fees at all: it sets no maximum amount, no percentage formula, no waiting period before a fee may be charged, and no requirement that a fee appear in a written lease, although as a practical matter a fee is collectible only if the parties agreed to it. One old default rule surprises people: unless the lease says otherwise, rent for lodgings is payable monthly at the END of each month under SDCL 43-32-12, an 1877-vintage rule that nearly every modern written lease overrides by making rent due on the first. Landlords should also remember that unpaid 'other funds due to the landlord pursuant to an agreement' — which would include agreed late fees — are among the amounts deductible from the security deposit under SDCL 43-32-24.

South Dakota late fees at a glance

Statutory cap	No statutory cap (see reasonableness standard and notes)
Mandatory grace period	None mandated statewide
Must be in the lease	Not addressed by statute
Daily fees	Not addressed by statute; a daily late fee would be a lease term policed only by ordinary contract and liquidated-damages principles — no South Dakota statute speaks to it.
Reasonableness standard	No statutory cap, formula, grace period, or express reasonableness standard exists for residential late fees — SDCL chapter 43-32 is silent on late charges entirely (verified negative: complete chapter read twice, 43-32-1 through 43-32-37). Enforceability rests on the lease and general contract law, including common-law limits on penalty clauses. The statutory default absent contrary agreement is that rents of lodgings are payable monthly at the END of each month (SDCL 43-32-12).

Notes and caveats

statutory_cap and grace_period_days null: verified negative — the complete text of every section of ch. 43-32 was read twice via two official endpoints; no late-fee provision exists anywhere in the chapter, and the 2025/2026 session sweeps found no late-fee bills. No secondary source claims any SD late-fee statute exists. must_be_in_lease null rather than true: no statute expressly conditions late fees on a lease term; the collection hook is contractual, and 43-32-24's deduction language ('other funds due to the landlord pursuant to an agreement') presupposes agreement without mandating a writing. The 3-day notice to quit in South Dakota's forcible entry and detainer law (SDCL ch. 21-16) is eviction procedure, not a rent grace period — do not render it as one. 43-32-12's end-of-month default applies '[w]hen there is no contract or usage to the contrary' — flag as a default, not a common practice.

How this record was verified: Direct read of statute text served by the official South Dakota Legislature site (sdlegislature.gov, SDLRC codified laws): the complete text of every section of SDCL chapter 43-32 (43-32-1 through 43-32-37, including all decimal sections and the repealed 43-32-7) read via the site's chapter endpoint, with every load-bearing section (43-32-6.1, 43-32-24, 43-32-13, 43-32-32, 43-32-12, 43-32-15) fetched a second, independent time via the per-section endpoint — all figures matched verbatim across reads (one month's rent cap; twenty-one days / forty-five days deposit clocks; $200 punitive ceiling; thirty-day modification notice with fifteen-day tenant termination right; twenty-four-hour written-notice entry presumption). SDCL 6-1-13 and 6-1-12 (rent-control preemption) double-read the same way. The 2026 amendment to 43-32-24 additionally pinned character-for-character from the official enrolled 2026 SB 4 (SL 2026, ch 179) and its introduced strike/underline version via the Legislature's document API; bill history from the official action log (signed by the Governor 2026-02-12; no effective-date clause, so effective 2026-07-01 under SDCL 2-14-16, read from the official site). Session sweeps run against the official bill lists: 2026 regular session (666 bills — SB 4 enacted and incorporated; HB 1231 on assistance-animal documentation tabled 2026-02-11, dead), 2025 regular session (571 bills — no landlord-tenant bills), 2025 special session (2 bills, corrections real estate only). Negative findings (no deposit interest or separate-account rule, no late-fee statute or grace period, no enumerated entry-reasons list) verified against the full chapter text in both reads. Note: sdlegislature.gov statute pages are JavaScript-rendered, but all text was read from the same official host's JSON/HTML API endpoints — no mirrors were needed or used.
