Which of the following are ordinances that specify construction standards?

Building codes are indeed the right choice as they specifically set forth safety, quality, and construction standards that must be adhered to during the building process. These codes are established by local governments and help ensure that structures are safe for occupancy and comply with community safety standards. They cover various aspects of construction, including structural integrity, electrical systems, plumbing, and fire safety.

While zoning laws, land use regulations, and environmental regulations play important roles in real estate development and property use, they do not primarily focus on construction standards. Zoning laws primarily dictate how land can be used (residential, commercial, etc.), land use regulations govern the development and use of land for various purposes, and environmental regulations involve laws that protect the environment and manage the effects of development on natural resources. Each of these has its own significance but does not specify the technical standards for construction like building codes do.
