Accessory Building

Definition and meaning of Accessory Building in real estate.

An accessory building is a secondary, detached structure located on the same parcel of land as the main home or building, designed to support the primary use of the property. Examples include detached garages, storage sheds, pool houses, and guest cottages.

In more detail

These structures are subordinate to the main residence and must comply with local zoning codes regarding size, height, and setback requirements. Setback regulations dictate how close a building can be constructed to property lines. Some municipal governments restrict accessory buildings from being used as independent living spaces or rental units.

Homeowners should check local zoning laws and obtain building permits before constructing any accessory building on their property.
