Types of Construction Defects

Construction defects usually include any deficiency in the performing or furnishing of the design, planning, supervision, inspection, construction or observation of construction to any new home or building, where there is a failure to construct the building in a reasonably workmanlike manner and/or the structure fails to perform in the manner that is reasonably intended by the buyer. Some of the most common and high-cost construction defects include:

  • Structural integrity - concrete, masonry & division, carpentry, unstable foundations
  • Expansive soils
  • Mechanical
  • Electrical
  • Water intrusion (often resulting in toxic mold)
  • Thermal and moisture protection
  • Doors, windows and glass
  • Finishes

Generally, courts categorize construction defects in one of four categories: design deficiencies, material deficiencies, construction deficiencies, or subsurface deficiencies.

Design Deficiencies

Design professionals, such as architects or engineers, who design buildings and systems do not al ways work as specified, which can result in a defect. Typical design deficiencies relate to building outside of the specified code. Roofs are an example of a typical design defect that result in water penetration, intrusion, poor drainage, or inadequate structural support.

Material Deficiencies

The use of inferior building materials can cause significant problems, such as windows that leak or fail to perform and function adequately, even when properly installed. Window leaks can result from many things including, rough framing not being flush with outside at openings, improperly flashed windows, improperly applied building paper, window frame racked during storage/moving, lack of sheet metal drip edge above window header, etc. Common manufacturer problems with building materials can include deteriorating flashing, building paper, waterproofing membranes, asphalt roofing shingles, particle board, inferior drywall and other wall products used in wet and/or damp areas, such as bathrooms and laundry rooms.

Construction Deficiencies

Poor quality workmanship can result in a long list of defects. A typical example is water infiltration through some portion of the building structure, which may create an environment for the growth of mold. Other problems include cracks in foundations or walls, dry rotting of wood, electrical and mechanical problems, plumbing leaks, or pest infestation.

Subsurface Deficiencies

Expansive soil conditions are typical in California and Colorado, as well as other parts of the country. Many houses are built on hills or other areas where it is difficult to provide a stable foundation. A lack of a solid foundation may result in cracked foundations or floor slabs and other damage to the building. If subsurface conditions are not properly compacted and prepared for adequate drainage, it is likely the property will experience problems such as improperly settling to the ground (subsidence), the structure moving or shifting, flooding and in many cases more severe problems such as landslides.
