Outbuilding

Definition and meaning of Outbuilding in real estate.

An outbuilding is any detached accessory structure, such as a barn, shed, garage, or workshop, that is located on a property in addition to the main residential or commercial building.

In more detail

These structures serve auxiliary purposes, providing extra storage, workspace, or agricultural shelter. The presence of outbuildings can influence the market value of a property, depending on their condition and utility. Buyers should check local zoning ordinances, which often regulate the size, placement, and height of these buildings relative to property lines.

Homeowners insurance policies typically cover outbuildings under the other structures section, but high-value structures may require additional coverage riders.
