What aspect is primarily regulated in non-restrictive zones?

In non-restrictive zones, the primary regulation focuses on the types of construction allowed. This means that there are generally fewer limitations on the kind of buildings or structures that can be developed in these areas. Non-restrictive zoning typically encourages a variety of construction projects, promoting flexibility, innovation, and diverse land uses.

In contrast, other choices such as environmental impact, overall height limits, and specific materials allowed often pertain to more regulated areas where specific criteria must be met to align with city planning goals, environmental standards, or community aesthetics. Non-restrictive zones prioritize the facilitation of development without imposing stringent controls or limitations on the nature of the buildings being erected, making the types of construction the focal point of regulation.
