This data identifies the maximum height of a building that may be erected on certain land. Clause 4.3 of the the Local Environment Plan (LEP) deals with building height, but clause 4.3 may also be subject to certain exceptions under other provisions of the Local Environment Plan (LEP). The HOB dataset describes the maximum building height allowed for areas. The height is defined as the vertical distance between ground level (existing) and/or AHD and the highest point of the building, including plant and lift overruns, but excluding communication devices, antennas etc.
The original GIS data was captured by local councils, DP&I and contractors and provided in accordance with the DP&I's Standard Requirements for GIS LEP data and Standard Technical Requirements for LEP maps. Before the LEP is notified on the NSW Legislation website, the mapping is checked by DP&I and the Parliamentary Council's Office to ensure that it is consistent with these standards. After the LEP is notified, the GIS data is quality controlled using an ISO 9001-Quality-Certified, Quality Management System and incorporated into the Statewide dataset.
Height of Building relates directly to and adopts the accuracy of its reference dataset, Land and Property Information DCDB. The GIS data may be subject to change as a part of quality control, or if the LEP is amended. Please confirm dates of respective features before use as this dataset has a large temporal extent.
