As a general rule, it is proposed that residential buildings within the densest area in the center of towns should be a minimum distance from front and rear boundaries to permit a light angle of 30 degrees. The light angle is measured between a vertical line from ground at the front (or back) fence and a line joining the highest point of the eaves (or parapet) to the same point at ground level.

The distance to front and back fences should be a minimum of 1/3 the height of the building. The road width has to be added if a road runs between the buildings. Light angles are used here as measurement of distance and not to secure a minimum quantity of light. As the sun stands high all year round the problem is not to provide light, but adequate ventilation and to avoid crowding and overlooking in to property. Setbacks are usually measured from the boundary line to the outer most parts of the building, unless otherwise specified.
