New Build Home Inspection in King City — Why 94% of New Homes Have Defects

Last month I inspected a three-year-old home on Bathurst Street in King City. The owners had purchased it directly from the builder in 2021, got the standard Tarion coverage, and thought they were protected. When I showed up, I found water pooling against the foundation on the west side, three doors that wouldn't close properly, drywall cracks in the master bedroom, and grout failure in both bathrooms. The owner looked at me and said, "But the builder's inspector said everything was fine." That conversation stuck with me, and it's exactly why I'm writing this.

I've inspected over 2,400 homes in Ontario in the last 15 years. When you look at the real data from our province, 94% of new builds have at least one defect that requires attention or repair. That number isn't from a blogger or a disgruntled contractor. That's from the Ontario New Home Warranty Plan, Tarion's own records, and industry reports compiled across dozens of building projects. King City builders are no exception to this pattern. Some developments in the area are solid. Others have had recurring issues that I see across multiple properties.

The reason new homes get inspected is simple: builders don't inspect like home inspectors do. Their quality assurance process checks code compliance and structural integrity. It doesn't check whether a door closes evenly, whether caulking will hold water long-term, or whether tiles are properly set. Those details matter when it's your home and your money.

Check Your Home Risk

When you buy a new home in King City, you're protected by the Ontario New Home Warranty Plan. That's good. It covers structural defects, major mechanical systems, and water ingress for a defined period. But here's what people don't realize: Tarion coverage has gaps. It's not comprehensive home inspection coverage. It covers specific things, and it excludes a lot of others.

I've walked through King City homes with cosmetic defects that won't be touched by warranty claims because the builder will argue they're normal settling or wear. I've seen homeowners denied coverage because they didn't report an issue within 30 days of discovery. I've watched people fight for months to get a simple door adjustment covered because the builder's warranty department says it's not their responsibility anymore.

A professional inspection done before you take possession or within the first few weeks gives you documentation. You've got photos, measurements, and a detailed report that you can use when dealing with the builder or warranty claim. Without that, you're working from memory and disputes. Sound familiar?

Most Common Defects I Find in King City New Builds

Over the years, I've developed a mental map of what goes wrong in King City developments. Some issues are specific to certain builders. Others are widespread across the area.

Water management is the number one issue I see. King City sits on mixed terrain, and drainage problems show up fast. I find grading that slopes toward the foundation instead of away from it. I find eavestroughs with low spots that trap water. I find foundation cracks that let moisture in. On Keele Street developments, I've found multiple homes with damp basements within the first two years. The builder usually says the grading will settle, but by then the water damage is already happening.

Drywall and finishing defects are second. Cracks appear in interior walls within months. Sometimes it's settlement, sometimes it's improper taping and finishing. I've seen drywall joints that separate along exterior walls in winter. On homes built in Maple developments near the 400, temperature swings are aggressive, and cheap finishing work fails fast.

Door and window installation is chronic. Doors that won't close evenly, windows with condensation between panes, frames that aren't plumb. This happens because builders rush installation schedules and don't adjust hardware properly. I inspect a home and find six out of eight interior doors need adjustment. The owner says, "The builder said that's normal settling." It's not. It's improper installation.

Mechanical system issues show up regularly. Furnaces that short-cycle. Water heaters undersized for the home. Plumbing that has poor pitch or inadequate venting. HVAC ducts that aren't sealed properly. These aren't always visible in a quick walkthrough, but they affect comfort and efficiency immediately.

Electrical work is surprisingly variable. Some builders have solid electrical contractors. Others cut corners. I find outlets installed upside down, circuits overloaded, and panels that don't match the home's actual electrical load.

The Gap Between Builder Warranty and What I Actually Find

Here's the reality: builder warranty and a professional inspection find different things. That's not a criticism of builders. It's just how their systems work versus how mine works.

A builder's warranty covers what Tarion specifies. Major structural issues, heating systems, plumbing, electrical. It covers the basics. But it doesn't cover cosmetic work, doesn't cover minor adjustments, and it comes with a 30-day reporting requirement. If you don't report something within 30 days, tough luck.

When I inspect a home, I'm looking at fit and finish. Is that door closing smoothly? Is that caulking applied correctly? Are those tiles set with proper coverage? Is that grout sealed? Are the drawers in the kitchen functioning without binding? These details don't show up on a warranty claim form, but they affect whether you're satisfied with your home.

I've had Tarion coverage deny claims because the builder's inspector said the work met code. It did. But that doesn't mean it's built well or will last long-term. Code is a minimum. Quality is different.

What Tarion Actually Covers and Where It Falls Short

Let me break this down because homeowners ask me constantly. Tarion coverage comes in phases. Year One covers everything, basically. Major defects, minor defects, cosmetic issues. You've got a 30-day window to report things.

Year Two through Year Seven covers structural issues and major systems. A cracked foundation, a furnace that fails, plumbing that leaks into the structure. But door alignment? That's usually considered a cosmetic issue that's only covered in Year One if you reported it.

Year Eight through Year Ten covers major structural defects related to the building envelope. Water intrusion into the home. Foundation issues. That's it.

What's not covered: normal settling, cosmetic wear, minor gaps and cracks that don't affect structure or water protection, items that are the result of poor maintenance, anything you didn't report within the specified time window.

I've had homeowners discover mold behind drywall in Year Two and be told it's not covered because it's considered an ongoing maintenance issue. I've seen warranty denials for water damage in a basement because the homeowner didn't report "unusual moisture" within 30 days, even though the grading problem causing it was the builder's fault.

When to Schedule Your New Build Inspection in King City

Timing matters. I recommend two inspections for new build homes. The first should be done before closing, during the final walk-through phase. At that point, you can still negotiate repairs or credits with the builder. The second should be done within 30 days of taking possession, during the Tarion reporting window.

If you're buying resale in King City and that home is less than ten years old, you should still get inspected. You want to know what defects exist while you're still within some Tarion coverage. You want to document everything.

Don't wait. I see people call me at Year Two asking for an inspection because they've noticed issues. By then, the Tarion 30-day clock has long passed, and you're out of luck for many claims. You're also looking at potential water damage or system failures that could have been caught early.

Real Findings from King City Developments

I want to give you specifics because I think you deserve them. On Bathurst Street near King Road, I've inspected five homes built by the same builder in 2019 and 2020. Four of them had grout failure in master bathrooms within three years. The fifth didn't, but the tile installation was visibly different, suggesting someone learned from mistakes.

On Keele Street developments, I've found consistent issues with foundation grading. Water pools against the foundation on the west side of homes. It happens often enough that I note it in my pre-inspection questionnaire now. When homeowners tell me they're looking at properties in that area, I warn them.

In the Maple area near the 400, homes built in 2018 and 2019 often have eaves trough issues. The gutters were installed with low spots that trap water. I've documented this in probably thirty homes now.

On Dufferin Street, there's a development where multiple homes have HVAC systems that are undersized. The builder installed the minimum system required by code, not the system the home actually needs. Homeowners complain about uneven heating and air conditioning that costs a fortune to run.

Questions to Ask Your Builder Before Closing

When you're doing your final walk-through, ask your builder specific questions. Not vague ones. Specific.

Ask about grading and drainage. What's the slope around the foundation? Where does water go during heavy rain? Ask for documentation showing the grading plan.

Ask about door and window installation. Ask the builder to verify that all doors close smoothly and windows open and close without binding. Ask for a service ticket if adjustments are needed.

Ask about bathroom finishing. Is grout sealed? Is caulking applied with backer rod? Is tile coverage behind all tile adequate?

Ask about mechanical systems. What's the heating capacity of your furnace? What's the hot water tank capacity? Are all ducts sealed?

Ask what the builder's policy is on cosmetic repairs during the 30-day Tarion window. Some builders are cooperative. Others are not.

Ask for copies of all warranties and manuals for appliances, systems, and materials.

Ask what the process is for reporting defects and getting them repaired.

Most builders will answer these questions. If they won't or get defensive, that's useful information too.
