Minnesota construction-defect cases often settle in the five-figure to low six-figure range, but the real answer is yes - you can sue after closing if the defect fits Minnesota's warranty laws and you meet the notice deadlines. The "you closed, so you're stuck" line is bad advice.

1. Check which Minnesota warranty fits the problem. Minnesota gives buyers of new homes statutory warranties under Minn. Stat. ch. 327A: 1 year for defects from faulty workmanship or code issues, 2 years for plumbing, electrical, heating, and cooling systems, and 10 years for major construction defects. A cracked tile is not the same case as water intrusion behind walls or a failing foundation.

2. Give written notice fast. This is where people miss valid claims. You generally must give the builder written notice within 6 months after discovering the defect. Waiting until after the holidays because everyone is "busy" can damage the claim. End-of-year panic is common, but the calendar does not pause because you just moved in.

3. Read the purchase and construction contracts. Many Minneapolis-area builder contracts try to steer disputes into arbitration, limit warranties, or require pre-suit procedures. Those clauses matter, but they do not erase Minnesota's statutory home warranties. Do not assume a "sold as is" phrase wipes everything out.

4. Get proof of the defect and repair cost. A home inspection report helps, but it is often not enough by itself. The stronger cases usually have a contractor, engineer, or building-envelope expert tying the damage to faulty construction and giving a repair estimate. Photos, moisture testing, invoices, and city inspection records from Minneapolis Community Planning & Economic Development can all matter.

5. Do not confuse an HOA problem with a builder problem. If the issue involves common elements in a townhome or condo, the HOA declaration may control who sues and who pays. Buyers often aim at the wrong target first.
