Key Takeaways
- Industry inspection data shows that the large majority of newly built homes have at least one major defect or code violation – meaning the odds are not in a new buyer’s favor.
- Chandler’s rapid growth in new home construction increases the risk of rushed builds, inexperienced labor, and overlooked defects.
- Passing a municipal code inspection does not mean a home is defect-free – code sets a legal minimum, not a quality standard.
- Builder warranties are tiered and time-sensitive; once the one-year express warranty expires, the window to get repairs covered at no cost largely closes.
- Certified inspectors use tools like moisture meters and methodical, system-by-system testing to find hidden defects that a visual walkthrough will never catch.
There is a common assumption that a brand-new home is a safe home. The framing is fresh, the paint still smells new, and everything looks flawless. But looks can be dangerously deceiving – and the numbers back that up.
Most New Homes Have Major Defects or Code Violations
Industry inspection studies have consistently found that the overwhelming majority of newly constructed homes contain at least one major defect or code violation. That is not a small margin of error. That is the overwhelming majority of new builds.
These are not all cosmetic issues. Many involve structural components, safety systems, and hidden moisture problems that will not show symptoms until months – or years – after move-in. By then, the builder’s warranty may have already expired, leaving the homeowner responsible for repairs that can run into the tens of thousands of dollars.
This is exactly why independent home inspections on new construction have become essential, not optional. Desert State Home Inspections serves Chandler, AZ and the broader Phoenix metro, specializing in new construction and one-year warranty inspections that give homeowners the documented evidence they need to hold builders accountable before that window closes.
Why Chandler’s Building Boom Raises the Risk
Chandler is one of the fastest-growing cities in Arizona, and that growth has reshaped entire neighborhoods in just a few years. New master-planned communities, infill developments, and large-scale tract housing projects have made Chandler a hotspot for new construction activity. That is great news for buyers looking for modern homes – but rapid growth comes with real tradeoffs in construction quality.
Rapid Growth and More Construction Shortcuts
When demand for new homes outpaces the supply of skilled labor, something gives. In high-growth markets like Chandler, developers are often juggling multiple active job sites, subcontractors are stretched thin, and quality control becomes inconsistent at best. Builders face enormous pressure from investors, lenders, and buyers to deliver finished homes on tight timelines.
Corners get cut – not always intentionally, but routinely. A roofer rushing to complete three houses in a week may miss flashing details. A plumber finishing a full cul-de-sac of homes in a single day may leave connections that are not fully sealed. An electrician working under deadline pressure may wire a panel that passes a basic inspection but does not meet the standard of safe installation. These are the kinds of findings that show up in inspection reports across new Chandler subdivisions every season.
Rushed Schedules and Inexperienced Labor
The labor shortage in the construction industry – which intensified following the pandemic – pushed many general contractors to rely on less experienced crews. New workers may not fully understand local building codes or the specific requirements of desert climate construction. Arizona’s extreme heat, monsoon moisture intrusion risks, and caliche soil conditions all demand construction knowledge that is not built overnight.
The result is a market where brand-new homes arrive with roofing defects, improperly installed HVAC ducts, drainage grading that channels water toward the foundation, and stucco systems that have already begun cracking before the homeowner unpacks. The defects are real, they are common, and in Chandler’s current construction climate, they are more likely than not.
The Most Common Defects Found in New Builds
Knowing what to look for is half the battle. Experienced home inspectors consistently find the same categories of defects appearing in new construction across the Phoenix metro area. Here is what tends to show up most often – and why each one matters.
1. Roofing Defects
Roofing problems are among the most frequently documented defects in new Chandler homes. Common issues include improperly installed flashing around penetrations such as pipes, vents, and skylights, inadequate underlayment overlap, and tiles or shingles that were not seated correctly. In Arizona’s intense sun and monsoon season, even a minor roofing flaw can escalate into significant interior water damage within one storm cycle.
One Desert State Home Inspections client, Brent Samuell, noted in his review:
“Had the first inspection done before closing and they found many, even significant, issues that I required the builder to address. I just had a second inspection done right before the builder warranty expires, and they also found additional items. The roof issues themselves made the fee worth it.”
That is a direct, real-world example of roofing defects surviving through the warranty period undetected – until a professional looked closely.
2. HVAC Ductwork Leaks and Malfunctions
In Arizona’s climate, a functioning HVAC system is not a luxury – it is a survival necessity. Yet HVAC-related defects are extremely common in new builds. The most frequent issues involve ductwork that was not properly sealed at connections, leading to conditioned air leaking into attic spaces instead of reaching living areas. Homeowners notice this as uneven room temperatures, higher-than-expected energy bills, and systems that run constantly without adequately cooling the home.
A case documented in new Arizona construction found significant HVAC ductwork leaks that only came to light during a pre-warranty expiration inspection. The homeowners had attributed their high cooling bills to the Arizona summer – not to the fact that a meaningful percentage of their air conditioning was being lost to the attic. Left unresolved, the strain on the system accelerates compressor wear and shortens the lifespan of the entire unit.
3. Plumbing Leaks Behind Walls
Plumbing defects in new homes are particularly dangerous because they are invisible until serious damage has already occurred. Pin-hole leaks at fittings, improperly sealed drain connections, and water supply lines that were not torqued to spec can all leak slowly behind drywall for months before showing any outward signs. By the time a water stain appears on a wall or ceiling, mold may have already begun growing in the cavity behind it.
In Arizona’s desert environment, many homeowners assume moisture problems are not a major risk. That assumption leads to delayed detection. Plumbing leaks behind walls in new construction are one of the primary reasons professional inspectors use moisture meters during every inspection – even in homes less than a year old.
4. Electrical Wiring Problems
Electrical defects in new homes range from missing knockout seals in panels and double-tapped breakers to improper grounding and GFCI outlet omissions in required locations such as bathrooms, kitchens, garages, and outdoor areas. These are not rare findings – they are among the most common items flagged in new construction inspection reports.
While some electrical defects are minor code corrections, others represent genuine safety hazards. Improper wiring can cause arc faults, electrical fires, or shock risks. Because electrical systems are largely concealed behind walls and inside panels, most homeowners would not recognize a problem during a standard walkthrough. An inspector who knows what to look for inside the panel and at every outlet can identify these issues before they become emergencies.
5. Stucco Cracks, Drainage, and Insulation Failures
Stucco is one of the most common exterior finishes on Arizona new builds, and it is one of the most frequently problematic. Improper mixing ratios, inadequate curing time, and missing control joints all lead to cracking that allows moisture intrusion – especially during monsoon season. In a desert climate this may seem counterintuitive, but stucco defects are a significant contributor to hidden wall moisture in Arizona homes.
Alongside stucco, improper grading – where the ground around the home slopes toward the foundation rather than away from it – is a drainage defect that can cause serious long-term foundation issues. Insulation failures, including gaps in attic insulation or improperly installed radiant barriers, reduce energy efficiency and can create condensation issues in certain conditions. These are all defects that Arizona inspectors encounter regularly in homes that are only months old.
Passing Code Does Not Mean Your Home Is Defect-Free
One of the most common misconceptions among new home buyers is that a successful municipal inspection means the home is problem-free. This is a dangerous assumption. Understanding the difference between a code inspection and a home inspection is critical before a warranty expires.
Building Codes Set Minimum Standards, Not Quality Benchmarks
Cities and counties across Arizona predominantly adopt and enforce building codes based on the International Residential Code (IRC), which establishes the baseline legal requirements for residential construction. The keyword is minimum. The IRC defines the lowest acceptable standard – not best practices, not quality craftsmanship, and not what a reasonable homeowner would expect from a $400,000 home.
A builder can meet every line of the IRC and still deliver a home with ductwork that leaks a significant portion of its airflow, roof flashing installed just barely enough to pass a visual review, or insulation that meets R-value specs on paper but was installed with gaps that reduce its real-world effectiveness. Code compliance is a legal floor. It is not a quality ceiling.
Code Inspections vs. Home Inspections: A Critical Difference
Municipal code inspectors are government employees tasked with confirming that a construction project complies with local ordinances. They review specific systems at specific stages of the build – not the finished home as a complete, functioning system. A framing inspection happens before drywall goes up; a plumbing inspection happens before walls are closed. By the time the home is finished, many of those systems are no longer visible to any inspector.
A certified home inspector, by contrast, evaluates the completed home as a buyer would experience it. They test every accessible system, probe for moisture at vulnerable points, inspect the roof up close, and document findings in a detailed report with photographs. Code inspectors have dozens of homes on their daily list. A professional home inspector’s sole focus is that one home, on that one day – looking for everything that could cause a problem for the people living there.
Your One-Year Warranty Is Expiring – Act Now
Builder warranties are not open-ended protections. They have specific structures, specific timelines, and specific limitations – and most homeowners do not read the fine print until it is too late. Understanding how these warranties are layered is the first step to using them effectively.
How Builder Warranties Are Tiered: 1, 2, and 10-Year Coverage
Most new home builder warranties follow a tiered structure that is fairly standard across the industry:
- Year 1: Covers defects in workmanship and materials – the broadest coverage, including cosmetic and functional issues throughout the home.
- Year 2: Narrows to cover mechanical systems, including HVAC, plumbing, and electrical.
- Year 10: Covers major structural defects only – foundation failures, load-bearing wall issues, and similar structural integrity problems.
The first year is by far the most broad. Once it expires, defects in finishes, ductwork, roofing details, plumbing connections, and hundreds of other components become the homeowner’s financial responsibility. That is why scheduling an inspection before the one-year mark – ideally at the 10- to 11-month point – is so important. It gives enough time to document defects, file claims, and pressure the builder to complete repairs before coverage ends.
Arizona’s Implied Warranty: Protection You Cannot Waive
Beyond the express written warranty a builder provides, Arizona law recognizes an implied warranty of workmanship and habitability on new residential construction. This implied warranty exists independently of whatever the builder’s contract says. Under Arizona Revised Statutes, builders are held to a standard of reasonable workmanship, and homeowners retain certain legal rights even if they waived parts of the express warranty.
This is meaningful protection – but it is not unlimited in duration, and it requires the homeowner to have documented evidence of the defect and when it was discovered. An inspection report generated before the one-year express warranty expires creates that documentation. It establishes a clear timeline that can be critical in any dispute with a builder over repair responsibility.
What You Lose After Express Warranty Expiration (And What Remains)
After the one-year express warranty expires, coverage for workmanship and materials is gone. What remains is the Year 2 mechanical system coverage and the 10-year structural warranty – significantly narrower protections. The implied warranty under Arizona law may still apply in some cases, but pursuing it typically requires legal action and documented evidence of the defect.
What this means practically: a plumbing leak discovered in month 13 that existed in month 11 – but was never documented – becomes the homeowner’s repair bill. An HVAC duct leak that inflated energy bills throughout the first year but was never formally identified stays invisible on paper. A professional inspection before the warranty closes turns undocumented problems into actionable warranty claims.
How Inspectors Find What Eyes Cannot See
A trained home inspector brings more than experience to a new construction inspection. The tools and methods used during a professional inspection are specifically designed to detect what a standard walkthrough – or even a careful homeowner – would never find on their own.
Moisture Meters and Methodical Inspection
A methodical, hands-on inspection evaluates each accessible system across the finished home. In practice, this means an inspector can identify areas where insulation is missing or improperly installed, where HVAC air is leaking into unconditioned spaces, or where moisture has intruded behind a wall – all without cutting into drywall or removing a single tile. The signs a wet area leaves behind are exactly the kind of clue a trained inspector is looking for.
Moisture meters work by measuring the electrical resistance or capacitance of a surface – water conducts electricity, so elevated readings signal moisture presence. Inspectors use them to probe around windows, doors, plumbing penetrations, and exterior walls to confirm or rule out water intrusion at vulnerable points. Used together, these methods give inspectors a non-invasive way to document what is actually happening inside the walls of a brand-new home.
For new construction specifically, these methods are invaluable. Everything looks pristine on the surface. Drywall is freshly painted, flooring is unscratched, and ceilings show no visible stains. But moisture meters and a methodical, system-by-system inspection do not depend on what a room looks like – they reveal what is actually happening inside the structure. That is the kind of objectivity that protects a homeowner’s investment.
Schedule Your Chandler Inspection Before Your Warranty Window Closes
The warranty clock on a new Chandler home does not pause. Every month that passes without a documented inspection is a month where hidden defects – in roofing, HVAC, plumbing, electrical, or stucco – go unrecorded and unclaimed. The cost of a professional inspection is a fraction of a single uncovered repair; a missed duct leak or a hidden plumbing issue discovered post-warranty can easily cost more than $5,000 to remediate without builder assistance.
The ideal window for a one-year warranty inspection is between the 10th and 11th month of ownership. This gives enough runway to document findings, formally notify the builder, and allow time for repairs to be completed before Year 1 express coverage expires. Waiting until month 12 risks running out of time for the builder to respond and act.
New construction buyers in Chandler are working through one of the most active home-building markets in Arizona – which also means one of the highest-risk environments for construction defects. An independent, third-party inspection is the clearest path to knowing exactly what was built, what was done right, and what the builder still owes before their obligation ends.
