What Is an Accessory Building

An accessory building or structure is a separate, non-habitable building that is located on the same property as a main building. These structures are used for various purposes such as storage, workshops, garages, or recreational activities.

They are typically smaller in size and visually distinct from the main building, providing additional functionality and aesthetic appeal to the property. Accessory buildings and structures often require proper permits and must meet zoning regulations and building codes before construction.

They serve as valuable additions to properties, offering extra space and flexibility for homeowners and businesses alike.

Definition Of An Accessory Building

An accessory building, also known as an accessory structure, refers to a separate structure that is supplementary to the main building on a property. These structures are not meant for habitation and are typically used for various purposes such as storage, recreation, or to house specific equipment or machinery.

Accessory buildings are commonly found in residential, commercial, and agricultural settings. They come in a wide range of sizes and designs, offering flexibility to property owners in terms of meeting their specific needs.

Purpose And Function Of Accessory Buildings

Accessory buildings serve multiple purposes and cater to a variety of needs. Some of the key reasons why property owners opt for accessory buildings include:

They can be customized to suit different purposes, such as a guesthouse, a playhouse for children, or a pool house. This adaptability allows property owners to maximize the use of their land and meet their specific requirements.

Local authorities may have specific requirements regarding setbacks, maximum height, and overall design that must be adhered to when constructing accessory buildings.
