height to eaves

The height of a facade from ground level to where the roof angles away from it.

The height to the eaves of a building is the vertical distance from ground level up to the point where the roof meets the facade at any angle. If the roof does not meet the facade (e.g. when it is sunken below a false front, screen wall, or cornice), then the full height of the facade is counted. In the case of a sloping roof, the height to the eaves is measured to the highest point along the lower edge of the sloping roof.

This height is not necessarily measured from the absolute base of the building. Rather, it measures the maximum height of the facade from ground level, with the exception that dormers and any degree of slope or setback constituting a roof or rooftop element are not counted. If the calculation of this height varies around the perimeter of a building, then the maximum is taken as the figure for the building as a whole.

The purpose of this height is generally to satisfy legal requirements in certain jurisdictions. Historically this standard has favored architectural innovations which enable buildings to exceed the maximum allowed height to eaves, for instance in France where mansard roofs allow a building to exceed the maximum by one or two floors.
