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 Indiana, construction law encompasses a wide range of legal areas as they relate to the construction industry. This includes the creation and enforcement of contracts, which are essential for outlining the responsibilities and expectations of parties involved in construction projects. Indiana's mechanic's lien laws provide a mechanism for contractors, subcontractors, and suppliers to secure payment for labor and materials provided on a project. These liens must be filed within a specific time frame and in accordance with state statutes, which can be found in Indiana Code Title 32, Article 28. Employment law is also a significant aspect of construction law in Indiana, addressing issues such as workplace safety, labor relations, and employee classification. Personal injury law comes into play when there are accidents or injuries on construction sites, and insurance law is crucial for managing risks associated with construction activities. Additionally, zoning and real estate laws in Indiana govern land use and the permits required for construction, while environmental regulations may impact how projects are planned and executed. It is important for those involved in construction to understand these laws and regulations to ensure compliance and to protect their legal rights.
