Minnesota · Construction-defect rights
Here is what you have, and here is how to keep it.
Minnesota has a statutory new-home warranty: one year on workmanship, two on major systems and ten on major construction defects due to noncompliance with building standards. Report a defect to the builder in writing within six months of discovering it, or the warranty claim is lost. The outer deadline is ten years from completion, with only two years from discovering a problem - so act quickly once you notice something.
What you have
The deadline does not protect a builder who concealed the problem.
In Minnesota, a claim of fraud, concealment or serious misconduct is not cut off by the ordinary construction deadline (Minn. Stat. § 541.051, subd. 1(a) ("Except where fraud is involved")).
You have a STATUTORY NEW-HOME WARRANTY by law: one year on workmanship and materials, two years on the plumbing, electrical, heating and cooling systems, and TEN YEARS on major construction defects due to noncompliance with building standards (Minn. Stat. s.327A.02). The deadline also yields to fraud - s.541.051 opens with "Except where fraud is involved." Otherwise, two years from discovery within a ten-year outer limit. To keep a warranty claim, report the defect to the builder in writing within six months of discovering it (s.327A.03).
The deadline
10 years to bring a construction-defect claim
Minn. Stat. § 541.051, subd. 1(a)
10 years from SUBSTANTIAL COMPLETION of the construction (Minn. Stat. § 541.051 subd. 1(a)) — framed as an accrual cap: the cause of action cannot accrue more than 10 years out, and once accrued must be sued within 2 years (the discovery limitations period). FRAUD CARVE-OUT: subdivision 1(a) opens with "Except where fraud is involved," which governs the whole sentence — so both the 2-year limitations and the 10-year repose yield where fraud is involved. OTHER EXCEPTIONS: the section does not reach claims for negligence in the maintenance, operation or inspection of the improvement against an owner/possessor (subd. 1(d)), and excludes equipment manufacturers/suppliers (subd. 1(e)). WARRANTY (separately verified, § 327A.02 subd. 1): statutory new-home warranty of 1 year (workmanship/materials), 2 years (plumbing/electrical/heating/cooling installation), and 10 years (major construction defects) — all keyed to noncompliance with building standards.
“Except where fraud is involved, no action by any person in contract, tort, or otherwise to recover damages for any injury to property, real or personal, or for bodily injury or wrongful death, arising out of the defective and unsafe condition of an improvement to real property, shall be brought against any person performing or furnishing the design, planning, supervision, materials, or observation of construction or construction of the improvement to real property or against the owner of the real property more than two years after the cause of action accrues, as specified in paragraph (c), nor in any event shall such a cause of action accrue more than ten years after substantial completion of the construction.”
Before you sue: Two readings exist. Minnesota's statutory home warranty requires written notice to the builder or home improvement contractor within six months of discovering a defect, or the warranty claim is lost (Minn. Stat. § 327A.03(a)). Once notice is given, the builder may inspect and offer a repair, and related suits wait for that process (§ 327A.02, subds. 4 and 7). One reading treats this as a condition of the warranty claim only; the other as a step before any related lawsuit. We rely on the first, so we do not list Minnesota as requiring pre-suit notice. Either way, give the written notice before you sue. (Minn. Stat. §§ 327A.02, 327A.03)
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. Minnesota has no general pre-suit notice rule for a defect lawsuit; see "Before you sue" on this page for any notice that does apply. A record made at the time is still 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.
