What type of buildings are exempt from the mandatory provisions of the code?

Historic buildings are often exempt from certain mandatory provisions of building codes to preserve their cultural, architectural, and historical significance. This exemption allows for the maintenance of their unique characteristics, which may not comply with modern building standards. Regulations might be relaxed to facilitate restoration and preservation efforts, recognizing that alterations to maintain the integrity of such structures can sometimes conflict with contemporary safety and accessibility codes.

In contrast, industrial, new constructions, and commercial buildings typically must adhere to the relevant provisions of the building codes to ensure safety, accessibility, and efficiency.
