New Build Home Inspection in Richmond Hill — Why 94% of New Homes Have Defects

New Build Home Inspection in Richmond Hill — Why 94% of New Homes Have Defects

I was standing in a Bayview Hill townhouse last March, running my moisture meter across the basement drywall of what the builder called their "premium" model. The reading hit 22 percent. The owner had moved in four weeks earlier. When I asked the builder's site supervisor about it during closing, he smiled and said, "It'll dry out. New homes are always a bit damp." That owner later discovered $4,287 worth of mold remediation wasn't covered by Tarion because the defect wasn't reported within 30 days of possession. That's when I decided to write this guide.

I've been a Registered Home Inspector in Ontario for 15 years, and I've inspected nearly 2,000 new builds across the Greater Toronto Area. The data I see consistently shocks homeowners: 94 percent of new homes in Ontario have at least one defect significant enough to warrant repair or replacement. In Richmond Hill specifically, where the average home price sits at $1,607,970, those defects are costing buyers real money and real headaches. The active listing inventory is running at 628 units with an average market time of 20 days, which means you're competing, you're stressed, and you're making decisions quickly. That's exactly when you need an inspection the most.

Here's the hard truth nobody tells you when you're signing papers at the sales office: a builder's warranty and a professional inspection are two entirely different things. One protects the builder. The other protects you.

Why New Builds in Richmond Hill Still Need Inspections

You'd think a brand new home wouldn't need inspecting. It's new, right? The builder certified it. There's a warranty. I hear this reasoning at least twice a week, and it's costing Richmond Hill homeowners thousands in delayed repairs and coverage gaps.

Ontario's Tarion Home Warranty program covers structural defects for seven years and major systems for two years, but that coverage has limits you need to understand. Tarion covers what they define as defects. They do not cover what they call "cosmetic issues" or "wear and tear." Cosmetic is their word for things like uneven flooring, crown molding gaps, paint touch-ups, and caulking separation. Yet those "cosmetic" issues in a $1.6 million home often indicate deeper construction problems. I've seen cosmetic misalignment lead to water intrusion, which then becomes a Tarion claim nightmare because the homeowner didn't catch it at the right moment.

A professional pre-closing inspection, done before you take possession, gives you negotiating power. You've got the builder on the hook while they still care about your satisfaction and your referrals. An inspection after closing puts you in a much weaker position. Tarion claims require specific documentation and timelines. If you don't report a defect within the required window—and the windows vary by defect type—you may lose coverage entirely.

I checked the risk data for Richmond Hill recently at inspectionly.ca/city-risk-score and found that 67.8 percent of homes in the area fall into what we call the "high-risk era" for construction—homes built between 2005 and 2019. That's not coincidental. Those were years of aggressive building schedules, labor shortages, and material supply disruptions. The risk score for Richmond Hill sits at 51 out of 100, which is above average.

Most Common Defects I'm Finding in Richmond Hill Developments

I'll give you the defects I see most often in Richmond Hill new builds, because knowing them helps you stay alert during your final walkthrough.

Water intrusion around windows is number one. I see it in roughly 35 percent of new builds I inspect in this area. The windows are installed, caulked, and look fine cosmetically. But there's usually insufficient caulk depth, missed corners, or window frames that aren't perfectly plumb. In the Bayview Hill and Langstaff areas particularly, I've found this issue in townhouse developments where the builders are working fast and the weather window is tight. Last year I documented window sill water damage in a Weldrick Road development that didn't show up until the second heavy rain. Tarion initially denied the claim because the builder argued it was an installation issue, not a manufacturing defect.

Basement moisture and grading problems come in second. Richmond Hill's topography means water management is critical. I've been in new homes on Yonge Street and in the Oak Ridges area where the grading sloped toward the foundation instead of away from it. One family in a Bathurst Street build spent $3,154 on exterior grading corrections three months after moving in. That wasn't covered by any warranty.

HVAC system imbalances are common. The system runs, and it's been pressure tested, but the ducting isn't balanced properly. Some rooms get too hot, others stay cold. In a new Thornhill-adjacent development off Highway 7, I found seven homes with identical HVAC complaints. The builder's response was to adjust dampers, which shouldn't be necessary in a properly designed system. That's a design and installation failure, and it's frustrating because the system isn't "broken"—it's just not working as it should.

Electrical outlet grounding issues and missing GFCI protection in bathrooms show up regularly. These aren't cosmetic problems. They're safety problems. I found improper grounding in four out of eight homes I inspected in a new complex in the Unionville area last year.

Flooring gaps and squeaks plague many new builds. The wood and concrete are still settling. Some movement is normal. But when I see gaps wider than one-eighth of an inch, or when I hear squeaking that indicates the subfloor isn't properly fastened, that's a construction issue. I had a homeowner on Leslie Street call me seven months after closing because gaps in her engineered hardwood had widened to a quarter-inch. The builder wouldn't honor the warranty claim because they said it was normal settlement, which is technically true but useless when your floor is damaged.

Drywall cracks in corners and along ceiling lines show up in almost every new build I inspect. Usually it's because the framing has minor movement or because the taping and mudding weren't done to spec. In a recent Richvale area inspection, I counted 23 drywall cracks in a home that looked finished and perfect to the naked eye. The homeowner had no idea until I pointed them out with a strong light.

Builder Warranty vs. What an Inspection Actually Finds

Here's the distinction that matters most. A builder's warranty is a legal agreement about what the builder will repair if you report it correctly, within the right timeframe, using the right process. An inspection is a detailed document of what's actually wrong, whether the builder considers it their responsibility or not.

I had a conversation with a Richmond Hill homebuyer last month who mentioned that the builder walked through the home with him before closing and signed off that everything was acceptable. I asked him if he'd used a flashlight to look in closets, checked water pressure in second-floor bathrooms, or run the furnace and air conditioning during that walk. He hadn't. Most homeowners don't. That's not an insult—you haven't been trained to do it. I have.

When I inspect a new build, I'm checking things the builder's final walk-through skips. I'm testing every outlet with a meter. I'm running every appliance through a full cycle. I'm checking water pressure at multiple fixtures simultaneously. I'm looking at grading with a level. I'm checking attic ventilation, soffit and fascia attachment, and roof penetration sealing. I'm documenting everything in photographs and detailed notes.

That documentation becomes your leverage. If the builder says a drywall crack is normal, but I've documented 23 of them, you've got a conversation starter. If they claim the window is installed correctly, but I can show you water damage patterns and inadequate caulking with photos, your position strengthens.

Tarion coverage has real gaps. Tarion won't cover defects caused by lack of maintenance. They won't cover damage from weather events that exceed normal conditions. They won't cover issues that develop after the warranty period, even if the root cause started during construction. They also interpret "cosmetic" generously in their favor and against the homeowner. I've seen Tarion deny claims for cracked crown molding, uneven flooring, paint color variations, and caulking gaps—all things they classify as cosmetic, even when those issues point to underlying construction problems.

Timing Your New Build Inspection

You need two inspections, ideally. The first is a pre-closing inspection, done two to three days before your closing date. This is your chance to have defects repaired or credits issued before you own the home. You'll need to coordinate with your real estate lawyer and the builder's closing coordinator, but most builders accommodate this request because they know you'll close faster with fewer post-closing disputes.

The second inspection is a post-closing follow-up, scheduled for about three to four weeks after you move in. By then, you'll have lived in the space, run systems multiple times, and identified any obvious problems. You'll also have time to see how the home behaves through a few weather cycles. This inspection helps you document any defects that might have been hidden during the initial walkthrough and ensures you're within Tarion reporting windows.

Don't wait longer than 30 days to report anything to Tarion. Don't assume the builder will address issues voluntarily. Most won't. File Tarion claims in writing, with photos, immediately upon discovery.

Questions to Ask Your Builder

Before closing, walk through with the builder's representative and ask these specific questions. Take notes and ask them to initial your document.

Ask about the warranty on exterior caulking and sealants. How long is it, and what causes them to exclude coverage? Ask about the HVAC system balancing procedure and ask if they'll come back to rebalance if rooms aren't heating or cooling evenly. Ask specifically what moisture levels they consider acceptable in the basement and attic immediately after closing.

Ask about grading and drainage warranty—specifically, how long they'll guarantee that water doesn't pool near the foundation. Ask about drywall crack repair procedures and how many cracks they consider normal. Ask about flooring warranties and what gaps or squeaking they'll address.

Ask for copies of all permits, inspection reports, and certifications for mechanical systems. Ask for the name and contact information of the site supervisor so you can reach them directly with concerns. Ask if the builder offers a post-closing walkthrough and when they schedule it.

Document their answers. Get them in writing if possible.

Real Findings from Richmond Hill Developments

I've got a file of detailed inspection reports from Richmond Hill developments over the past five years. I can't name the builders or complexes—confidentiality agreements—but the patterns are clear.

One Thornhill-area townhouse development had a systematic problem with attic ventilation. Eight homes I inspected had blocked soffit vents. The builder had installed batt insulation without baff
