Walk into any new-construction sales office along 93rd Avenue or US 41 in St. John and you'll see some version of the same brochure line: a ten-year warranty, printed in bold, sitting near the floor plan. The ten-year figure refers to one of the warranty periods described below.
Builders working in town, from Olthof Homes to Schilling Development to Phillippe Builders, operate under Indiana's New Home Construction Warranty Act. The statute lets a builder trade away broader, undefined common-law protections for a narrower, insurance-backed package with hard stop dates. Buyers who read "ten years" and stop reading are the ones most likely to be surprised later.
What the Ten Years Actually Covers
Indiana Code 32-27-2-8 lays out four separate clocks, not one. Each starts on the same warranty date, but they don't end together.
| Coverage | Duration | What It Includes |
|---|---|---|
| Workmanship & materials | 2 years | General defects in how the home was built or the materials used |
| Mechanical systems | 2 years | Plumbing, electrical, heating, cooling, and ventilating installation (not the fixtures or appliances themselves) |
| Roof & roof systems | 4 years | Workmanship or material defects in the roof |
| Major structural defects | 10 years | Actual damage to load-bearing parts of the home from soil subsidence, expansion, or lateral movement |
The ten-year figure that makes it onto marketing material is the last row only, and it's the narrowest of the four. The statute defines "major structural defect" specifically as damage to load-bearing elements caused by soil movement, and it explicitly excludes damage caused by flood, earthquake, or other natural disaster. A cracked foundation from poor grading might qualify. A failed sump pump three years after closing does not, because that clock already closed at year two.
By year five in a St. John new build, three of the four warranty periods have already lapsed. Only the structural clause is still running, and it covers a narrower category of problems than most buyers assume when they hear the word "structural."
How the Statutory Warranty Relates to Implied Warranties
Indiana builders aren't required to offer any of this. The statutory warranty exists because it lets a builder disclaim the broader implied warranties of habitability and workmanlike construction that would otherwise apply under Indiana common law, warranties with no fixed expiration built into a specific number of years.
To make that disclaimer valid, the builder has to meet several conditions at once. The statutory warranties have to be written into the contract in plain terms. The builder's warranty obligations have to be backed by an insurance policy at least equal to the home's purchase price. The builder needs completed-operations liability coverage for consequential damages. And the disclaimer itself has to appear in at least 10-point boldface type, with the buyer signing a specific acknowledgment that they read it, understood it, and agreed to it.
If any of those pieces are missing, the disclaimer may not hold, and the broader implied warranties could still be in play. That's worth a specific question to your closing attorney rather than an assumption either way: did the builder's disclaimer actually meet every element the statute requires, or just some of them.
The 60-Day Notice Process
Say something does go wrong within the covered window. Indiana law doesn't let you go straight to a lawsuit. Under IC 32-27-3-2(a), a homeowner has to serve the contractor with written notice of the claim at least 60 days before filing any legal action. The contractor then has 21 days to respond, and the response has to be one of three things: propose an inspection with a timeframe attached, offer a settlement without disputing the claim, or state outright that they're disputing it.
The detail that trips people up isn't the paperwork. It's the instinct to fix the problem yourself while you wait. According to Anthem EAP, bringing in an outside contractor to make repairs during that window can cancel the warranty protection you were trying to use, because the builder never got the chance to inspect or cure the defect themselves. If you notice a problem in year one or two, the sequence matters as much as the notice itself: written claim first, then wait for the response, then let the builder attempt repair before anyone else touches it.
The Same State Law, Very Different Stakes
Because the statutory warranty floor is identical everywhere in Indiana, the real variation in St. John shows up in what sits on top of it, and that changes a lot depending on which subdivision you're comparing.
Streamside, built entirely by Olthof Homes and completed in 2024, sold in the $500,000 to $575,000 range for a mix of ranch and two-story homes in the Hanover school district. Summerlin Estates, technically in St. John but carrying Dyer mailing addresses, has sold in a similar $450,000 to $575,000 band. The Enclave spans a wider $400,000 to $700,000 range within Lake Central schools. All three carry a homeowners association, typically scoped to maintaining ponds, entrance signage, and shared landscaping, on top of whatever the state warranty covers.
The Continental and Estates of Wellington sit at a different level of oversight entirely. The Continental, developed by Schilling Development as St. John's only gated community, spreads 52 lots across more than 55 acres with natural and man-made lakes, with lots starting in the $250,000s and finished homes typically landing between $1 million and $2 million. Estates of Wellington, another Schilling community, is built around a restrictive set of covenants governing everything from minimum square footage to roof pitch to window materials. In both communities, the HOA is doing real work that the statutory warranty doesn't touch at all, dictating what gets built and how it looks years after the builder's last walkthrough.
Two buyers closing on new construction in St. John this fall, one in a Streamside tract home and one in a Continental custom estate, are covered by the identical statutory warranty language. What differs is how much additional oversight sits on top of that floor, and how long it lasts after the warranty clocks run out.
What This Fall's Numbers Say About Your Leverage
As of the end of August 2026, St. John had 92 new homes listed for sale at a median list price of $510,000, with most sitting on the market roughly 69 days and typically drawing a single offer. That's not a market where builders are fielding bidding wars on spec inventory. It's a market with room to negotiate on the terms that surround the warranty, not just the price of the home itself.
The pipeline behind those listings is still expanding. The St. John Plan Commission approved a final plat for Preserve West Phase 3 at its May 20, 2026 meeting, alongside a two-lot subdivision on Matson Drive, and recommended the Town Council accept a $52,000 performance bond for Park West Phase 1. The Council followed through on that bond in June, along with a $77,000 letter of credit for Preserve SJ LLC covering Preserve West Unit 3. New product keeps entering the market at a pace that gives buyers real comparison points rather than a fixed, aging inventory list.
That combination, a soft-offer environment plus an active builder pipeline, is exactly the moment to ask for something in writing beyond the statutory minimum: a written confirmation of the warranty date, a copy of the insurance backing the builder's disclaimer, or an extended workmanship period on specific line items you're worried about. None of that requires a lawyer at the negotiating table. It requires knowing the statutory floor well enough to recognize when a builder is offering something above it, or nothing at all.
A Few Questions Worth Asking Before You Sign
What if my builder never had me sign a disclaimer document at all? Then the broader implied warranties of habitability and workmanlike construction may still apply, since a valid disclaimer requires specific written language, insurance backing, and a signed acknowledgment. Absence of any of those elements is worth flagging to a real estate attorney before you assume you're limited to the statutory minimum.
Can I just have my own contractor fix a covered defect and bill the builder later? That approach risks forfeiting the warranty claim entirely, since the builder is entitled to the chance to inspect and cure the problem first. Send the written notice, wait through the 21-day response window, and let the builder's own process play out before bringing in anyone else.
If you're weighing new construction against resale in St. John, or trying to figure out which builder's warranty terms actually protect you once the model-home signage comes down, Better Homes and Gardens Real Estate Connections can walk through the contract language with you before you're the one signing it.
