The annual Sydney housing supply forecast does not explicitly forecast or include the following dwelling types:
The department provides key data on some of these other forms of housing in recognition of their role in helping meet the needs of Sydney’s diverse and growing population.
Secondary dwellings and dual occupancies refer to lots that have added a second dwelling. This sort of development is relevant to the overall housing supply in Sydney and is a type of housing that can increase density in established areas. Figure 3 shows the key differences between dual occupancies and secondary dwellings.

The main differences between the two are:
Although the department's forecasting methodology does not cover secondary dwellings, it may cover dual occupancies both in the development pipeline (as development consents) and in completed new homes (as separate water connections with Sydney Water, our proxy for dwelling completions).
The best source of information on secondary dwellings is the Local Performance Development Monitor.
The department has collected approvals data by local government area (LGA) for 2006–07 to 2019–20 from the Local Performance Development Monitor for dual occupancies and secondary dwellings. Approvals include development applications and complying development certificates (Note: we have not included LGAs with fewer than 100 approvals over the period). To improve the accuracy of this information and align with existing published data, we have refined our data processing and reporting method from our 2020 release. Due to this refinement, some LGAs have experienced changes to their overall count of approvals.
The map in Figure 4 shows the total number of approvals by new LGA boundaries from 2006–07 to 2019–20.

We compiled a pipeline of other forms of housing, excluding secondary dwellings and manufactured home estates, using CoreLogic's Cordell Connect Australia Project database. The pipeline refers to:
The purpose was to identify and track the scope and breadth of ‘other dwelling’ developments that will contribute to the diversity of Sydney’s future housing supply. As at June 2021, based on planning information (projects in the system) there was potential across Sydney for:
5,830 units within 170 developments
18,670 bedrooms within 476 developments
4,220 beds within 36 developments
Note that we have rounded totals to the nearest 10.
Note: you cannot directly compare the two products because the Sydney housing supply forecast counts dwellings and the other forms of housing pipeline counts bedrooms/units/beds.
The chart in Figure 5 shows the ‘other dwellings’ pipeline broken down to sub-categories of units, bedrooms and beds. We have also broken down each LGA to show how many of each accommodation type are in the pipeline for the LGA.

Factors that drive demand for other forms of housing in an LGA include:
Generally, independent seniors housing is reported as the number of units, boarding houses (including student accommodation) as the number of bedrooms and beds and aged-care facilities as the number of beds.
