Construction Codes in USA

Construction regulation in the US operates through a decentralized framework, with responsibility largely resting with state and local governments. Development projects are governed by zoning and construction codes, covering land use and building design and construction. Model codes developed by the International Code Council provide a common foundation, but states can adopt them with their own amendments, creating variations across jurisdictions. Additionally, compliance continues throughout the project lifecycle, with different requirements and reviews at each stage, from planning and permitting through construction and final occupancy.
