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

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

Last month I inspected a new build on Dunvegan Road. The home was finished three weeks prior, the owners had just closed, and they felt confident based on the builder's orientation and the Tarion certificate hanging in the hallway. During my walk-through, I found twelve separate defect items—three of them construction-related problems that the warranty wouldn't touch, and two that fell into the grey zone where Tarion coverage remains unclear.

This is the reality I've encountered across 15 years of home inspections in Ontario, particularly in Forest Hill where new construction has accelerated over the past decade.

I want to start by saying something directly: buying a new home doesn't exempt you from needing an independent inspection. That's a common misconception, and it costs homeowners money they didn't expect to spend later.

The data backs this up. Ontario's condominium and home defect reports show that roughly 94 percent of new homes built in the past ten years have at least one defect identified during a third-party inspection. I'm not referring to cosmetic issues or minor finishing touches. I'm talking about structural concerns, moisture intrusion, electrical oversights, and mechanical failures that compromise the home's integrity or safety. When I walk through a new Forest Hill property, I find defects in approximately nine out of ten inspections. Sometimes it's a single item. Often it's multiple.

The reason isn't that builders are careless. It's that new construction is complex, timelines are compressed, and the builder's incentive differs from yours. A builder wants to move units and manage costs. You want a home that functions properly and won't develop problems in year two or year five.

Forest Hill presents its own particular challenges. The neighbourhood spans a large area with varied topography. Many of the developments built in the last eight to twelve years—around Bathurst and Bloor, closer to Avenue Road, and throughout the tree-lined streets near the Forest Hill Gardens area—sit on properties with established drainage patterns and mature soil conditions. When excavation and foundation work happens quickly, water management becomes critical. I've identified moisture seepage in basements, improper grading around foundations, and inadequate perimeter drainage in at least 40 percent of the new builds I've inspected in Forest Hill.

The electrical work is another consistent trouble spot. Loose connections, reversed polarity on outlets, and GFCI protection missing from wet areas turn up regularly. In one inspection on Old Forest Hill Road, I found that the kitchen island outlets weren't GFCI protected despite being within six feet of the sink. Kitchen cabinets had been installed over the outlet, so the issue wouldn't have surfaced until something failed or created a shock hazard.

Drywall taping, joint compound finishing, and paint prep represent the most visible defect category. These aren't structural, but they're annoying and costly to fix after occupancy. Unfinished drywall seams, paint bleeding into trim, and caulking gaps around windows and doors appear in nearly every new home. In Forest Hill's higher-end finishes, where expectations are elevated, this becomes more noticeable. I documented these issues on properties ranging from $1.2 million to $3.8 million, and they exist equally across price points.

HVAC commissioning is frequently incomplete. The heating and cooling systems run, but they haven't been balanced, the ductwork hasn't been sealed properly, and the thermostat programming doesn't match the owner's needs. I've walked into homes where one zone is overheating while another remains cold, directly traceable to installation shortcuts.

Plumbing rough-ins sometimes include cross-connections, inadequate slopes for drainage, or shut-off valves installed in inaccessible locations. During one Dunvegan Road inspection (not the same home I mentioned earlier), the main water shut-off was positioned behind a false wall in a utility closet. The owner would've needed to disassemble drywall to access it in an emergency.

Now, you might be wondering about builder warranty and Tarion coverage. Here's where I need to be candid with you.

Tarion, Ontario's new home warranty provider, covers structural defects, water intrusion, and major mechanical failures within specific timeframes. Structural defects carry a seven-year window. Major defects like roof leaks or foundation cracks are covered. But Tarion's coverage has gaps, and builders know those gaps well.

The warranty excludes cosmetic issues, minor settling, paint imperfections, and anything deemed normal wear or maintenance responsibility. It also excludes defects caused by owner misuse or acts of nature. Defining "normal" is where disputes arise. A crack that's structural gets covered. A crack that's settling doesn't. The determination isn't always clear-cut, and you'll spend time and potentially legal fees arguing the distinction.

The builder's own warranty is typically one to two years and covers items they personally installed or are contractually responsible for. After that, you're relying on Tarion and the trades' insurance. Many defects fall into a gap where Tarion says it's not their responsibility and the builder says the period has elapsed.

This is precisely why an independent inspection before closing is essential. You catch problems while you still have leverage with the builder. Post-closing, your options narrow significantly.

Timing matters. I recommend scheduling your inspection for the day before closing. The home should be fully complete, furnished only minimally, and the builder should still be responsive to defect lists. Some buyers inspect earlier, but you risk items being missed or new issues arising between inspection and occupancy. The day-before timing gives you the strongest position.

When you're in the home, ask your builder these questions directly. What was the specific start date for foundation work, and what site drainage measures were installed before the dig? Walk the mechanical room and ask for the HVAC commissioning report and the plumbing schematic. These documents should exist. If the builder hesitates or says they're "in the system," that's a red flag. Ask about water intrusion testing—did they conduct blower door testing or water testing on the envelope? Many don't, and defects only appear months later. Ask about grading and final drainage verification. Confirm that all electrical outlets in wet areas are GFCI protected and that the installation passed municipal inspection.

These questions aren't confrontational. Most builders expect them. The answers reveal whether construction quality was genuinely prioritized or whether speed was the main driver.

After 15 years, I've inspected homes across Toronto's most established neighbourhoods. Forest Hill represents a strong market with excellent properties, but new construction there carries the same defect risk as anywhere else in Ontario. The difference is that Forest Hill buyers often have the resources to address problems early, and they should use that advantage.

Don't skip the inspection because the home is new. Don't assume the builder caught everything. Don't rely solely on Tarion to resolve issues later. Get an independent inspection, ask specific questions, and document everything before you close.
