1Special residential and non-residential uses in residential zones
Background
The ACT Planning and Land Authority is currently undertaking a general review of policy in the Territory
Plan that regulates development in residential zones. As part of this review, this issues paper discusses
non-standard and non-residential uses in residential zones and invites comment on possible policy
changes1.
While most housing in residential zones takes the form of either a standard single dwelling 2 or a
multi-unit development (including dual occupancies), certain other non-standard forms of residential
development are assessable in the Territory Plans merit track3. These include habitable suites,
relocatable units4, boarding houses, guest houses, special dwellings, residential care accommodation,
retirement complexes, and supportive housing.
Some non-residential developments are also assessable in the merit track in residential zones in specic
circumstances. These include ancillary uses, child care centres, community activity centres, health
facilities, home businesses, minor uses, and temporary uses.
Key questions in this paper have been identied based on ACTPLAs recent experiences and research.
However, these are intended only as a basis for discussion, and suggestions about additional potential
issues and policy measures are welcome.

1. The range and restriction of uses permitted in residential areas
A key aspect of any planning framework is the range and regulation of uses within particular zones. For
example, various uses permitted in residential zones other than standard housing including boarding
houses, childcare centres, community activity centres, residential care accommodation, health facilities,
and guest houses are subject to certain restrictions on their location (see the appendix to this paper).
These location restrictions of non-residential uses are intended to protect the amenity of residential
zoned areas by preventing agglomeration (i.e. by permitting only one such development per section),
while recognising that in some circumstances the location of these uses in residential zoned areas may
nonetheless be desirable.
Another current residential zones use restriction is a maximum plot ratio of 35 per cent for boarding
houses, child care centres, community activity centres, and residential care accommodation. In
contrast, in the same areas the maximum plot ratio for single dwellings is 50 per cent.
Comment is sought as to whether these restrictions might be revised, and whether more broadly, the
current range of merit assessable uses permitted in residential zones should be altered.
Questions
1. Is the current range of uses permitted in residential zones appropriate?
2. Are restrictions limiting only one of certain uses per section appropriate?
3. Is a maximum plot ratio for some uses of 35 per cent appropriate?

2.Habitablesuites,relocatableunits,andsecondarydwellings/subsidiary
residences(grannyats)
There is a social need for secondary residences associated with existing dwellings, which planning
should allow for. Such secondary residences can potentially play an important role in contributing to
social sustainability in the Territory.
Both the ACT Affordable Housing Action Plan (Phase 2) (Chief Ministers Department August 2009)
and the Draft Positive Ageing Strategy (Department of Disability, Housing, and Community Services -
July 2009) have raised the possibility of increasing the supply of granny ats in the context of improving
housing affordability and providing appropriate housing for the ageing population.
The Territory Plan currently provides for two types of temporary granny athabitable suites and
relocatable units. These two uses were introduced to the Territory Plan in 1997, following Variation 55.
Ahabitable suite is dened as:
a room or suite of rooms which is capable of being occupied as a separate domicile within adwelling but easily reverted to being rooms forming part of that dwelling.
This might take the form of the conversion of a part of, or an extension to, a larger existing single
dwelling. While they may have their own kitchen and bathroom facilities, habitable suites are not
regarded as a separate dwelling and thus are not subject to policy for dual occupancies. Notably, dual
occupancies are subject to a number of restrictions, including plot ratio limits and requirements that
they can only be developed on a block greater than 800m 2. Thus, habitable suites provide an option for
the limited, temporary, extension of the housing capacity of an existing dwelling, particularly when a dual
occupancy would not be permitted.
The current policy for habitable suites includes the following requirements:
Applicants must submit a statutory declaration that the habitable suite will only be occupied
by a person who is providing care to a resident of the main dwelling or receiving care from a
resident of the main dwelling due to reasons of inrmity (due to age) or disability.
Documentation must be provided to show how the suite will be reintegrated back into the main
dwelling once care is no longer required, including how kitchen facilities are to be removed.
The suite may only have a maximum gross oor area of up to 70m and an additional parking
space is to be provided.
Arelocatable unit is dened as:
a room or suite of rooms capable of being occupied as a separate domicile which is designed
and constructed in a manner which enables it to be easily transferred to and/or re-erected on
another site.
A relocatable unit provides the opportunity to construct free standing temporary care accommodation,
in situations where a dual occupancy is not permissible.
The current policy for relocatable units has the following features:
Applicants must submit a statutory declaration that the relocatable unit will only be occupied
by a person who is providing care to a resident of the main dwelling or receiving care from a
resident of the main dwelling due to reasons of inrmity (due to age) or disability.
The unit may only have a maximum gross oor area of up to 70m and an additional parking
space is to be provided.

The unit is sited and designed so that: the height of walls does not exceed 3.5m; the unit is
at the rear of the main dwelling; and the minimum setback from any window or opening in the
main dwelling is no less than 3.5m.
However, for the following reasons an argument can be made that the concepts of habitable suite and
relocatable unit need to be replaced, or substantially revised:
1. There have only been around 80 applications to develop habitable suites since 1997. A
compliance issue is whether they are being reintegrated into the primary dwelling following the
end of their occupation by the residents specied in their development applications.
2. The recent change to the denition of dwelling, contained in the Planning and Development
Regulation 2008, allowing a dwelling to have two kitchens has probably removed the need for
habitable suite as a use. A development application for a granny at as part of an existing
house might now be made as an extension of the dwelling.
3. There have been even less applications to develop relocatable units since 1997. Again, a
compliance issue is whether they are being removed (relocated) following the end of their
occupation.
4. The current restrictions on the occupation of a habitable suite or relocatable unit to people
recieving care or carers create compliance difculties.
5. Currently, permanent semi-independent domiciles physically separated from the main
structure of a dwelling are not permissible (i.e. relocatable suites are temporary structures and
habitable suites must be attached to a larger dwelling). A new use might thus allow for such
housing.
Accordingly, this paper proposes two broad options:
the retention and potential revision of the policy content of habitable suite and relocatable unit or
the deletion of these uses from the Territory Plan and their replacement with a new use,
nominally named, secondary dwelling (other naming options include subsidiary residence, or
granny at).

RecentNSWpolicychange-grannyats(secondarydwellings)
New provisions for secondary dwellings (or granny ats) have recently been introduced in NSW in a new
State Environmental Planning Policy (Affordable Rental Housing) 2009, gazetted 31 July 20095. The new
provisions are potentially relevant to both the options in this paper. The new NSW policy provides for:
Secondary dwellings of up to 60m may be developed on blocks in all residential zones largerthan 450m (although councils also have the discretion to approve them on smaller blocks).
Secondary dwellings may not be constructed as a new basement or on top of the roof of an
existing dwelling.
Subdivision of blocks with a secondary dwelling cannot take place.
The total oor area of the primary dwelling and secondary dwellings cannot exceed any
maximum set for the block under any other planning instrument.
A block can have no more than one secondary dwelling.
No additional parking is required to be provided.
Two clear contrasts between the NSW policy and the ACTs current habitable suite and relocatable unit
policies are the absence in NSW of a care requirement or an expectation of temporary use. In NSW
secondary dwellings can be occupied by family members of the occupants of the main dwelling (e.g.
teenagers, extended family members, older people) wishing to live semi-independently but not requiring
or providing care due to reasons of age or disability. Further, in NSW the granny at can also be rented
to non-family members.
Key Point
If a new use of secondary dwelling reecting policy changes in NSW was introduced in the ACT it isenvisaged that it would be particularly attractive to owners of properties where dual occupancy is
currently not permissible (i.e. blocks smaller than 800m, which form a majority of residential blocks
across the Territory).
Questions
4.For the reasons outlined in this paper, (e.g. given the recent change to the denition of a dwelling to
allow two kitchens, compliance issues, and their low uptake since 1997), should habitable suite and
relocatable unit be replaced with a new use (e.g. secondary dwelling or subsidiary residence)?
5 (A). If habitable suite and relocatable unit are retained should any other changes to policy be made inthe ACT (potentially reecting new policy in NSW) in relation to:
maximum size
parking requirements
restrictions on occupation (care or family requirements)
common private open space requirements
common metering for water/electricity
number of habitable suites/relocatable units on a block?

5 (B). If a new use is introduced, what policy characteristics should this use have in relation to:
its name (secondary dwelling, granny at, subsidiary residence)
maximum oor space of secondary dwelling
whether oor space of secondary dwelling is included in the current 50% maximum plot ratio
for main dwelling
minimum block size on which secondary dwelling permissible
any additional parking requirement
any restriction on occupation (care or family requirements)
any requirement for common use of private open space
restrictions on subdivision/unit titling
requirement for common metering of services (water, electricity, gas etc)
requirement that dwellings not separately rated
requirement that no separate waste collection service provided
separate mail box permitted

3.Institutionalhousing:boardinghousesandstudentaccommodation
Along with standard dwellings, secondary dwellings, and housing for older persons requiring varying
degrees of care, there is an additional need to provide for institutional housing in the Territory Plan.
The most common forms of such housing are boarding houses and student accommodation, which
while usually serving distinct social groups, in practice often have similar built forms. These include
the presence of shared common spaces and facilities, frequently accompanied by less independently-orientated private living spaces relative to standard apartments.
3 (A) Boarding houses
Boarding houses have ambiguous perceptions in the housing market. On one hand they are frequently
viewed negatively as insecure and substandard housing-of-last-resort for those who would be otherwise
literally without a roof over their heads due to poverty and/or other complex issues (their residents are
typically described as the tertiary homeless within conceptual hierarchies of homelessness). On the
other hand, for these very reasons, boarding houses are sometimes presented positively as an essential
means of reducing the number of people sleeping rough (the primary homeless)6,7.
Accordingly, given their place at the base of the housing market it may be desirable to introduce some
basic standards based on those recently introduced in NSW to protect the well-being of boarding
houses often vulnerable residents.
The standards for New Generation Boarding Houses in NSW provide that:
The gross oor area of a boarding room for a single occupant is no smaller than 12m, or 16m
in any other case.
Boarding rooms may not be occupied by more than two adults.
Adequate bathroom and kitchen facilities are provided within the boarding house for the use
of residents. Individual boarding rooms may have kitchen and/or bathroom facilities, but theseare not mandatory.
If a boarding house is to be occupied by ve or more adults, at least one communal living
room is to be provided.
Private open space of at least 20m2 with a minimum dimension of 3m is provided for the use of
the lodgers.
Currently, there is no specic policy relating to boarding houses in the Territory Plan other than
restrictions on external appearance, plot ratio, and agglomeration (see Section 1.5 in the appendix to
this paper).
6 Additionally, it is recognised that this accommodation is the preferred form of housing for a small proportion of their
residents typically people with low incomes who do not wish to settle down, or enjoy boarding houses institutional orcommunal nature.

3 (B) - Student accommodation
As the number of students seeking tertiary education in Canberra grows, specialised student
accommodation is likely to become an increasingly common form of institutionalised housing. However,
there is currently no policy specic to such developments in the ACT, with new developments beingassessed against the generic relevant Residential Zones Housing Development Code.
In contrast, other jurisdictions, conscious of the social inclusion challenges that their student
populations pose, and the increasing importance of the international education sector within their urban
economies, have introduced basic standards. For example, the Adelaide City Council has the following
policy standards for new student accommodation developments8:
Minimum internal oor areas:
studio (where no separate bedroom): 37m
1 bedroom: 50m2
2 bedroom: 75m2
3+ bedrooms: 100m2
Private open space:
studio - no minimum requirement but some provision is desirable
1 bedroom dwelling/apartment - 8m
2 bedroom dwelling/apartment - 11m
3+ bedroom dwelling/apartment - 15m

Questions
6.How should institutional housing, such as boarding houses and student accommodation, be provided
for in the Territory Plan?
7. Should common policy apply to both boarding houses and student accommodation? (Or alternatively,
should Student Accommodation be introduced as a new use?)
8. What should the policy features of these uses be in terms of:
minimum room sizes
common space requirements
storage requirements
unit-titling restrictions
private open space requirements?
9.What parking requirements are appropriate for boarding houses and/or student accommodation?(The current standards for boarding houses are: 0.5 space per employee, and 0.5 space per bedroom).
10.Should boarding houses be restricted to a maximum number of bedrooms to prevent the
agglomeration of persons likely to be highly disadvantaged?
