South Dakota compliance obligations
South Dakota landlords commonly track 4 state and local compliance obligations, each listed below with its schedule, its sources, and the date we last verified it. Among them: file SD annual report by the 1st of your entity's anniversary month, pay first-half SD property tax by April 30, and pay second-half SD property tax by October 31.
File SD annual report by the 1st of your entity's anniversary month
If your South Dakota rental property is held in an LLC or corporation formed in or registered with South Dakota, the entity must file an annual report ($55 online, $70 on paper) with the Secretary of State by the first day of its anniversary month (the month it first filed there); a report still unfiled two months later draws a $55 late fee and risks administrative dissolution, and starting in 2027 an entity may elect a January 31 due date instead.

Pay first-half SD property tax by April 30
South Dakota property tax is paid to the county treasurer in two halves, and a first half not paid or postmarked by April 30 becomes delinquent on May 1 and draws interest of five-sixths of one percent for each month or part of a month (10% a year), while a total bill of $50 or less must be paid in full by April 30.

Return security deposit or send written statement within 21 days of move-out
South Dakota law (SDCL 43-32-24) requires returning the security deposit, or giving the tenant a written statement of the specific reasons for withholding any part of it, within 21 days after the tenancy ends and you have the tenant's mailing address or delivery instructions, plus an itemized accounting of any amount withheld within 45 days after the tenancy ends if the tenant asks, and missing these requirements forfeits the right to withhold any of the deposit.

Seasonal maintenance for South Dakota
Landlords in South Dakota plan upkeep around a cold climate: this guide lists 9 seasonal maintenance items for South Dakota in calendar order, each with its timing and the date we last verified it. Among them: check sump pumps and drainage before spring snowmelt, smoke and CO detector seasonal test, and spring thaw inspection: roof and foundation.
Check sump pumps and drainage before spring snowmelt
Spring snowmelt and early rain, which drove major March and April floods in eastern South Dakota, run off saturated or frozen ground toward foundations, so testing the sump pump and clearing drainage before the melt catches a failed pump before the basement floods.

Smoke and CO detector seasonal test
An annual full test of smoke and CO detectors (beyond battery swaps) confirms every alarm actually sounds.
Around March · Verified before August 2026
Spring thaw inspection: roof and foundation
Freeze-thaw cycles crack roofs and foundations; a spring inspection catches winter damage early.
Around April · Verified before August 2026
Inspect roofs for hail damage after summer storm season
Large hail in South Dakota peaks in June and July and stays common through August, so an early September roof check, with photos, finds storm damage that went unnoticed while it can still be reported to the insurer promptly and repaired before winter.

Line up snow removal contract in early fall
Snow can arrive in October (the October 3 to 5, 2013 blizzard dropped 23 inches on Rapid City), reliable snow contractors fill their schedules early, and Sioux Falls, Rapid City, and Aberdeen require property owners to clear sidewalks soon after snowfall, so signing a contract in September locks in service before the first storm.

Winterize exterior plumbing and irrigation by mid-September
Median first freezes reach most of South Dakota in the last third of September, earlier in the Black Hills and parts of the northwest and about one to two weeks later along the Missouri River, and in about 1 year in 10 a freeze arrives by mid-September across much of the state, so draining hose bibs, disconnecting hoses, and blowing out irrigation lines by September 15 keeps a frozen line from bursting and flooding the home.

Furnace inspection before heating season
A pre-season furnace inspection prevents mid-winter heating failures and carbon monoxide risk.
Around September · Verified before August 2026
Protect pipes for deep-winter cold and plan checks on empty properties
Most nights from November through March fall to freezing or below in South Dakota and subzero lows cluster in December through February, so insulating exposed pipes, keeping the heat at 55 degrees or higher, and arranging regular checks on empty properties keeps a heat failure from freezing and bursting pipes before anyone notices.
