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 Arizona, construction law encompasses a wide range of legal areas as they relate to the construction industry. This includes the regulation of mechanic's and materialmen's liens, which are legal claims made by contractors and suppliers for payment for work performed or materials provided. Arizona Revised Statutes Title 33, Chapter 7 outlines the process for filing and enforcing these liens, as well as the necessary steps for their removal once payment has been made. Construction contracts in Arizona are governed by contract law principles, which dictate the terms and obligations of the parties involved. Employment law is also relevant, as it covers the rights and responsibilities of construction workers and employers, including wage and hour laws, workplace safety, and workers' compensation. Personal injury law comes into play when there are accidents or injuries on construction sites, with potential liability for negligence. Insurance law is important for managing risks associated with construction projects, including coverage for property damage and liability. Additionally, zoning law and real estate law are integral to construction law in Arizona, as they regulate land use, building codes, and the acquisition and development of property. Attorneys specializing in construction law in Arizona must navigate this complex intersection of statutes and regulations to effectively represent their clients in the construction industry.
