Building Code

by | Jan 21, 2026

A building code is a comprehensive body of laws and regulations that governs the construction, alteration, use, occupancy, and repair of buildings to ensure public health, safety, and welfare. These codes establish minimum standards for structural integrity, fire safety, electrical and plumbing systems, energy efficiency, accessibility, and the quality of materials and workmanship used in construction. Building codes are adopted and enforced by state and local governments under the state’s police power, which allows regulation to protect the general public. Compliance with applicable building codes is typically mandatory, and violations can result in fines, required corrective work, denial of occupancy permits, or other legal consequences. In real estate, building codes play a critical role in determining whether a property may be legally constructed, renovated, occupied, or sold.
