California Supplemental (CSE) Practice Exam

What is the minimum size requirement for building alterations to fall under the Cal Green code?

1. 500 ft.²

2. 1,000 ft.²

3. 2,000 ft.²

4. 3,000 ft.²

The correct answer is: 1,000 ft.²

The minimum size requirement for building alterations to fall under the Cal Green code is established at 1,000 square feet. This threshold is important because it delineates which projects must comply with the sustainability measures outlined in the Cal Green code, promoting energy and resource efficiency. Cal Green was created to enhance the environmental performance of buildings and includes a range of measures applicable to both new constructions and alterations. Understanding the 1,000 square feet requirement helps architects, contractors, and builders determine when they need to incorporate green building practices into their projects. When alterations meet or exceed this size, it triggers the necessity to adhere to the relevant green building standards, ensuring that larger projects contribute positively to California's environmental goals. The other size options represent figures that exceed the threshold for compliance with Cal Green, meaning they do not apply in this context. Therefore, focusing on the 1,000 square feet requirement is crucial for anyone involved in building projects within California, ensuring they follow the necessary guidelines and regulations related to sustainability.
