ANS does not address ventilation. It is addressed by the ____________________.

The correct answer is that ventilation is addressed by local building codes. Building codes are a set of regulations established by local governments which dictate the minimum standards for construction and safety, including aspects like ventilation. These codes are designed to ensure that buildings maintain adequate air quality, provide effective air circulation, and comply with safety standards.

Local building codes are essential as they can vary significantly from one jurisdiction to another, reflecting the specific needs and conditions of the area, such as climate and urban density. Compliance with these codes is mandatory for any construction or renovation project, ensuring that all structures are safe and habitable.

While environmental standards might cover broader or more specialized issues related to air quality and pollution, they do not typically focus on the specifics of building ventilation in the same residential or commercial context as local codes. State laws can also set guidelines, but it is local codes that provide the actionable and detailed regulations necessary for compliance in specific areas. Lastly, property management guidelines pertain more to the operation and maintenance of properties rather than the regulatory aspects of construction and the building's infrastructure, making the local building codes the primary source for ventilation requirements.
