The Minnesota Home Warranty:

The statutory warranty for defects in construction in a property is found in Minnesota Statutes Section 327A.02. This statute provides the following warranty for home, or "dwelling" owners:

Subd. 1. Warranties by vendors. In every sale of a completed dwelling, and in every contract for the sale of a dwelling to be completed, the vendor shall warrant to the vendee that: (a) during the one-year period from and after the warranty date the dwelling shall be free from defects caused by faulty workmanship and defective materials due to non-compliance with building standards; (b) during the two-year period from and after the warranty date, the dwelling shall be free from defects caused by faulty installation of plumbing, electrical, heating, and cooling systems due to non-compliance with building standards; and (c) during the ten-year period from and after the warranty date, the dwelling shall be free from major construction defects due to non-compliance with building standards.

Minnesota Statutes 327A.02 defines "major construction defects" as referenced above in part (c) as follows:

Major construction defect means actual damage to load bearing portion of dwelling of the home improvement, including damage due to subsidence, expansion or lateral movement of soil, which effects the load bearing function and which vitally affects or is eminently likely to vitally use of the dwelling or the home improvement for residential purposes. Major construction defect does not include damage due to movement of soil caused by flood, earthquake or other natural disaster.

Liability of the vendor [the builder] or the home improvement contractor under 327A.01 to 327A.07 is limited to the specific items set forth in Sections 327A.01 to 327A.07 and does not extend to the following:

Loss or damage not reported by the vendee or the owner to the vendor or the home improvement contractor in writing within six months after the vendee or the owner discovers or should have discovered the loss or damage.
