Construction law is a general reference to various areas of law as applied to the design, engineering, and construction of buildings—including residential buildings and commercial buildings—as well as bridges, roads, pipelines, railroads, water transmission and distribution systems, electrical power transmission systems, sewerage systems, and other structures.

In addition to the law governing the filing and removal of mechanic’s and materialmen’s liens (also known as contractor liens), construction law includes contract law, employment law, personal injury law, insurance law, zoning law, and real estate law.

In Virginia, construction law encompasses a wide range of legal areas as they relate to the construction industry. This includes the creation and enforcement of mechanic's and materialmen's liens, which are legal claims made by contractors and suppliers for payment for work performed or materials provided. Virginia Code outlines specific procedures for filing and enforcing these liens. Additionally, construction contracts in Virginia are governed by contract law principles, which dictate the terms and conditions of agreements between parties involved in construction projects. Employment law is also relevant, as it covers the rights and obligations of construction workers and employers. Personal injury law comes into play when there are accidents or injuries on construction sites, and insurance law is important for managing risks associated with construction activities. Zoning and real estate laws in Virginia affect where and how structures can be built, including compliance with local ordinances and land use regulations. Each of these areas of law works together to regulate the construction industry, ensuring legal compliance and protecting the interests of all parties involved.
