A buyer closes on a new build in Plymouth in March. In July, a hairline crack shows up along a basement wall. Nothing alarming, just enough to notice. Most people file it away, thinking they have until next March, a full year, before the builder's warranty runs out. That assumption is the mistake. Minnesota's statutory warranty law does not give a buyer twelve months to report a problem. It gives six months from the day the defect is discovered, and the clock starts the moment you notice the crack, not the moment the warranty itself expires.

This distinction matters everywhere in the state, but it matters more in Plymouth than in a subdivision built by a single production builder pouring identical foundations on identical lots. Plymouth has very little raw land left to develop. What gets built here now tends to be custom lots, association-maintained villa communities, and infill projects tucked into established streets rather than large master-planned tracts. That variation in who builds and how means the warranty clock, and the paperwork trail behind it, is doing more of the protective work than most buyers realize.

The warranty is a state law, not a builder favor

Builder marketing often describes warranty coverage like a bonus, something extra thrown in to make the deal feel generous. It is not optional and it is not the builder's to withhold. Minnesota Statutes Chapter 327A creates a mandatory warranty on every new home sold in the state, and the law is explicit that it cannot be waived except under narrow, defined circumstances.

The statute breaks coverage into three separate time periods, not one blanket year:

"the dwelling shall be free from defects caused by faulty workmanship and defective materials"

That one-year language covers general workmanship. A second period, two years, covers the mechanical systems: heating, cooling, plumbing, and electrical. A third period, ten years, covers major structural defects. Three different clocks, three different scopes, all running from the same warranty date, which is the day you take possession.

The part almost nobody reads: the six-month notice window

Buyers who do read the fine print usually stop at the 1-2-10 structure and assume that's the whole story. The procedural half of the statute is where the real friction lives. Once you discover a defect, you have six months to send the contractor written notice. Miss that window and you can lose the right to make a claim, even if you are still well inside the one-year, two-year, or ten-year coverage period.

After you send notice, the contractor has 30 days to inspect the problem. Following that inspection, the contractor has 15 days to deliver a written offer to repair. These are not builder courtesies. They are deadlines set in the statute itself, and the Minnesota Attorney General's homeowner handbook lays out the same notice-and-repair sequence for anyone who wants to read the source material directly.

Here is how that plays out against what most buyers assume walking into closing:

That third row is worth sitting with. A warranty that survives a sale is unusual protection, and it means a Plymouth buyer purchasing a five-year-old build still has a live structural claim if a genuine defect surfaces, as long as notice goes out within that six-month discovery window.

Why this bites harder on a custom lot than in a subdivision

Production subdivisions built by a single company tend to standardize quality control because the same crews and the same floor plans repeat across dozens of homes. A defect on lot 14 tells the builder something about lot 15. Plymouth's current new-construction market does not work that way as often. Because the city is largely built out, much of what's under construction right now sits on individual custom lots or inside smaller, builder-specific communities rather than sprawling tract developments.

Walk through what's actually active in the city and the pattern is clear. Hanson Builders markets Hollydale, a small luxury community near Wayzata High School, as a custom-build neighborhood rather than a fixed set of repeated floor plans, and Gonyea Custom Homes has also built there. David Weekley Homes has single-family product underway in Brinda on 65-foot homesites. The Villas at Timbers Edge is another small, association-maintained villa community in the city. Perl Gardens is a small run of attached twin homes built for main-level living. Stonegate Builders has a home under construction in Woodland Hills with a completion window projected for this month, September 2026.

Every one of those is a different builder, different crew, different level of quality-control repetition. That is not a knock on any of them. It is simply the math of a built-out suburb: less land means fewer identical tract homes and more one-off or small-batch construction, which means each individual home's inspection trail matters more, not less.

The inspection sequence that protects you

The Minnesota Star Tribune has covered the three inspection stages that matter for a new build: pre-drywall, final, and the one-year warranty inspection, sometimes called the 11-month inspection because it needs to happen before the statutory year closes. A pre-drywall inspection catches framing and rough-in problems while walls are still open, before insulation and sheetrock hide them. The final inspection, done shortly before closing, is the one to prioritize if you can only do one. The 11-month inspection exists specifically to catch anything that surfaced after move-in, while there is still time to file a proper written notice under the statute.

On a custom or small-batch build, that final walkthrough deserves more attention than a buyer might give it in a production subdivision where the builder has ironed out the kinks over dozens of nearly identical closings before yours. Keep your own punch list. Photograph anything you flag. Send notice in writing the moment you notice something, not months later when you assume you still have time.

A short FAQ

Does the warranty transfer if I buy a Plymouth new-construction home from its original owner? Yes. The statutory warranty survives the sale and stays attached to the home for whatever remains of the one-year, two-year, and ten-year periods, regardless of who holds title.

What if the builder is no longer in business when I find a defect? Minnesota's Contractor Recovery Fund exists for exactly this situation. Compensation is available, though the fund can reduce or prorate payouts if it is fielding claims against the same builder from multiple homeowners at once.

Does this apply to a custom home built on my own lot, or only to production subdivisions? The statute applies to any new home sale and any home improvement contract for major structural work, regardless of whether it's a custom build, a small builder community, or a large subdivision. The coverage scope is the same either way.

Plymouth's new-construction market rewards buyers who read past the sales brochure. Knowing which builder is behind a given community, what its warranty actually covers, and when your clock starts ticking is the difference between a protected purchase and a missed deadline. If you're weighing a custom lot, a villa community, or a resale that's still inside its statutory window, the Holmers Group can walk the build with you and help you read the paperwork the way it's meant to be read.
