Allegations of construction defects are a frequent cause for concern — and legal headaches — for many contractors.
A construction defect is a problem in the design, construction, or maintenance of a home or building that causes damage, safety issues, or a loss in value.
There are generally four different types of defects
Some defects are obvious — like a leaking roof or uneven floors — while others stay hidden for years until they cause major problems behind the scenes. Regardless of the type, construction defects frequently give rise to disputes among homeowners, contractors, builders, architects and insurance companies. Defects generally fall into one of these categories:
- Design defects: These originate in the plans or specifications drafted by an architect or engineer. Even if the contractor builds everything correctly, a flawed design, such as improper drainage planning or undersized structural supports, can set the entire project up for failure.
- Workmanship defects: These occur when construction work isn’t performed to industry standards. Examples include improperly installed windows, faulty electrical work or inadequate waterproofing. Poor workmanship is one of the most common sources of construction disputes.
- Material defects: Sometimes the issue isn’t the design or the labor, but the products used. Defective roofing materials, substandard concrete or failing plumbing components can all cause serious damage, even when installed correctly.
- Failure to meet codes: If the project doesn’t meet local building codes — or if the contractor fails to deliver what the contract requires — it may be considered a defect. This includes anything from missing structural components to unsafe wiring that violates code.
Construction defects can lead to serious financial losses for all involved. No matter what your side of the issue, it is wise to seek legal guidance.
