Residential Density is the measure of the residential development on a specific site or within a specified geographic area. This is usually expressed in terms of either the number of dwelling units or the number of bedrooms per unit of land area. Residential density may be calculated on the basis of gross or net land area.
The use of standards governing residential density is to control the amount of residential development so that the resulting level of development can be:
- Accommodated on the land without the destruction of the physical or environmental character of the area;
- Serviced adequately by the existing and planned infrastructure and social facilities;
- Provided with adequate open space;
- In balance with the function of the particular area;
- Respectful of the rights of residents to enjoy adequate light, ventilation, views, and privacy.
The actual gross or net density which is permitted on a particular site depends on the size of that site, the physical characteristics of the site and the general density standard established in relevant area plans and policies for the area in which the site is located.
The permitted maximum residential densities are as follows:
- Low Density: 5 lots/units per acre
- Medium Density: 10 lots/units per acre
- High Density: 17 lots/units per acre
The lot area for individual buildings must be sufficient to allow space for the building and other essential activities. In addition there must be Physical Planning and Development Authority provision for convenient access for pedestrians, natural light, privacy, ventilation
