Which type of permit is required for parts of a project with very special functions or uses, as indicated in the building permit application?

The type of permit required for parts of a project with very special functions or uses, as indicated in the building permit application, is a special use permit. This permit is specifically designed for uses that may not be permitted by zoning laws under normal conditions but are allowed under specific circumstances. These circumstances often include unique aspects of the proposed project that warrant a closer examination and consideration by zoning boards or other regulatory bodies.

A special use permit ensures that the proposed use aligns with the overall goals of the local zoning ordinances while also taking into account the unique characteristics of the project. This might include factors such as community impact or compatibility with surrounding uses, making it essential for projects that don't fit the standard definitions or criteria outlined by existing zoning laws.

In contrast, accessory permits are typically related to minor structures or uses that are secondary to the primary use of a property, construction permits are general permits required to ensure that building codes are followed during construction, and utility permits address the installation or modification of utility services. Each of these serves a distinct purpose that does not specifically apply to projects with unique or special functions as highlighted in the question.
