South Dakota · Construction-defect rights
Here is what you have, and here is how to keep it.
South Dakota bars construction-defect suits against designers and builders more than ten years after substantial completion. It expressly removes that protection where the defendant committed fraud, fraudulent concealment or willful/wanton misconduct, still possesses/controls the improvement, or gave a longer express warranty. For residential defects you must first serve notice and allow a 30-day inspect-and-offer window.
What you have
The deadline does not protect a builder who concealed the problem.
In South Dakota, a claim of fraud, concealment or serious misconduct is not cut off by the ordinary construction deadline (SDCL § 15-2A-7).
Past the deadline for a defect? A contract claim may still be alive.
The construction deadline here bars tort claims — but the repose does not prohibit an action within a longer express warranty/guarantee period (SDCL § 15-2A-8)Someone told “you’re past the deadline” may still have a live contract or warranty claim, and typically no one volunteers that.
If the builder or developer still controls the property, the deadline isn’t theirs to raise.
The exception most homeowners would never think to ask about: repose not assertable by a person in actual possession or control (owner, tenant or otherwise) when the deficiency proximately causes injury/death (SDCL § 15-2A-4) It matters most where a builder still controls part of a project — a phased subdivision, an unfinished condo association.
THE DEADLINE DOES NOT PROTECT FRAUD, CONCEALMENT OR WILLFUL MISCONDUCT. South Dakota's ten-year bar (SDCL § 15-2A-3) cannot be raised by a defendant guilty of fraud, fraudulent concealment, fraudulent misrepresentation, or willful or wanton misconduct (§ 15-2A-7) — nor by a party still controlling the property, nor to defeat a longer written warranty. For residential defects, serve written notice first; you may not sue until 30 days later, or sooner if the builder refuses to fix it (SDCL §§ 21-1-15, 21-1-16).
The deadline
10 years to bring a construction-defect claim
SDCL § 15-2A-3
10 years from substantial completion (SDCL § 15-2A-3). FRAUD CARVE-OUT: the chapter's limitations "may not be asserted as a defense by any person who is guilty of fraud, fraudulent concealment, fraudulent misrepresentations, or willful or wanton misconduct" (SDCL § 15-2A-7). Nor by a person in actual possession/control when the deficiency proximately causes injury/death (§ 15-2A-4); nor to defeat a longer express written warranty (§ 15-2A-8). Residential presuit notice suspends the period for a 30-day inspect/offer window.
“No action to recover damages for any injury to real or personal property, for personal injury or death arising out of any deficiency in the design, planning, supervision, inspection, and observation of construction, or construction, of an improvement to real property ... may be brought against any person performing or furnishing the design, planning, supervision, inspection, and observation of construction, or construction, of such an improvement more than ten years after substantial completion of such construction.”
Before you sue: South Dakota requires written notice to the construction professional, and you may not sue until 30 days after serving it, or sooner if the professional refuses to fix the defect. A suit filed early is paused until the notice step is complete. (SDCL §§ 21-1-15, 21-1-16)
What to do now
Write it down the day you notice it. Photograph it with something for scale. Note the date, the room, and what you saw. If it gets worse, photograph it again - a sequence is far stronger than one picture. Keep every message with the builder. You are not starting a fight; you are keeping the option open. South Dakota requires written notice to the builder before you sue: see "Before you sue" on this page for the exact rule. Describe each defect in reasonable detail; a record made at the time is what most people are missing later.
The same defect, a different answer next door
The construction-defect deadline is a state-by-state accident of geography. The identical crack in the identical house can be dead in one state and live in another.
