Which type of buildings are exempt from certain provisions of the code?

Historic buildings are often exempt from certain provisions of the mechanical code due to their unique architectural features and the preservation goals associated with maintaining their historical integrity. Many regulations are tailored to contemporary construction standards, which may not be compatible with the original design and materials used in historic structures.

The exemption allows for flexibility in maintaining and restoring these buildings so that their historical significance is preserved. This can involve alterations or repairs that would otherwise violate modern code requirements, thus ensuring that the history and cultural value of the building remain intact while still providing for essential safety and operational measures.

Understanding this context highlights the importance of balancing safety and preservation when it comes to historic properties, allowing them to continue serving their communities without losing their historical essence.
