Common Disputes Affecting Contractors
The disputes between a property owner and those hired to perform project work, whether as construction or renovation or maintenance projects, frequently end up in court. In some courts, such as the Small Claims Court, with a $35,000 limit per Plaintiff, defective workmanship cases are among some of the most commonly occurring cases. Allegations often include defective work or incomplete work.
Challenges
Disputes involving construction or renovation projects are often challenging due to the many legal issues that typically apply within the realm of construction law. Common issues may involve the extent of, and quality of, evidence required, such as the need sometimes for an independent witness to inspect and provide a reports as to what workmanship was done correctly and what workmanship was done incorrectly thus whether the required workmanship standards were met. Disputes involving construction or renovation projects are often additionally troublesome as contractors and property owners alike will frequently begin a lawsuit without first obtaining proper legal advice.
Additionally, litigation arising from construction or renovation disputes often extends into legal issues beyond allegations of poor quality of work and also include legal issues such as quantum meruit disputes over the value of partially completed work, consumer rights concerns, mitigation requirements, among other issues.
