Council Approval for Attached Dwellings (Terraces & Townhouses on Separate Lots)
An attached dwelling is one dwelling in a row of two or more, each sitting on its own separate lot, sharing one or more walls with the dwelling next door - the Torrens-title terrace or townhouse model. It is a different land use from multi dwelling housing, where several dwellings sit together on a single lot. Attached dwellings are usually assessed by development application, addressing boundary setbacks, acoustic separation between the shared dwellings, and streetscape requirements, though some low-rise housing diversity forms can qualify for the fast complying development pathway where every design criterion is met.

A housing type defined by title, not just appearance
An attached dwelling looks, from the street, much like a townhouse row. What actually defines it is that each dwelling sits on its own separate lot and title, sharing one or more walls with its neighbour - distinct from multi dwelling housing, where several dwellings occupy a single lot under one title until subdivided. Getting this classification right at the outset matters, because it determines which controls and which approval pathway apply.
The controls that come up most often
Boundary setbacks for the shared wall, acoustic separation standards between the attached dwellings, and streetscape or frontage requirements addressing how a row of dwellings presents to the street are the recurring assessment issues for this housing type.
Pathway
Most attached dwelling proposals go through a development application, assessed on merit against the LEP and DCP. Some low-rise housing diversity forms can qualify for complying development where every design criterion is satisfied in full - we check this early, since it changes both timeframe and documentation requirements substantially.
How it works
Classification and zone check
2-4 business days
Confirming attached dwelling versus multi dwelling housing, and zone permissibility under the LEP.
Pathway assessment
3-5 business days
Whether any part of the design can use a low-rise housing diversity CDC pathway, or whether a DA applies to the whole scheme.
Documentation
3-6 weeks
Setback, acoustic and streetscape-compliant plans plus any supporting reports.
Lodgement and assessment
6-14 weeks
Managing council through to determination, including any design amendments requested.
What we take off your hands
What EHUP handles
- Confirming whether your proposal is legally an attached dwelling and not multi dwelling housing
- Checking boundary setback and shared-wall controls under the relevant LEP and DCP
- Coordinating acoustic separation requirements between neighbouring dwellings
- Addressing streetscape and frontage requirements in the design
- Checking eligibility for the fast complying development pathway where it exists
- Preparing and lodging the development application and managing it to determination
What you don't have to deal with
- Designing a row of dwellings without confirming the correct land-use classification first
- Underestimating the acoustic separation standard between attached dwellings
Frequently asked questions
What is the actual difference between an attached dwelling and multi dwelling housing?
Title. An attached dwelling is one home on its own separate lot, sharing a wall with the dwelling next door - each owner holds an individual title. Multi dwelling housing is several dwellings grouped on a single lot, typically around shared driveways or common property, with one underlying title until it is subdivided. The built form can look similar from the street; the legal structure is different, and it changes which controls and which approval pathway apply.
What acoustic requirements apply between attached dwellings?
Shared walls between attached dwellings need to meet acoustic separation standards set by the Building Code of Australia and, in some cases, additional council DCP requirements. This affects wall construction type and is worth confirming at design stage rather than at construction certificate stage.
Can attached dwellings ever be complying development?
In some cases, yes - certain low-rise housing diversity forms are eligible for complying development where every applicable design criterion, including setbacks, building separation and streetscape controls, is satisfied in full. Where any criterion is not met, the pathway reverts to a development application.
What streetscape requirements typically apply?
Controls addressing building frontage width, garage and driveway location, front setback consistency with neighbouring properties, and articulation of the street-facing facade are common in DCPs for this housing type, since a row of attached dwellings has a visible cumulative effect on the street.

Multi Dwelling Housing
Multi dwelling housing is three or more dwellings on a single lot, commonly villas or townhouses grouped around a shared driveway or common property, held under one title until it is subdivided.
Low & Medium Density (LMR)
Low and medium density residential development - dual occupancies, manor houses, terraces, townhouses and multi-dwelling housing - sits in the most contested part of the NSW planning framework.
Low & Mid-Rise Housing
The Low and Mid-Rise Housing reforms allow terraces, manor houses, and residential flat buildings of two to six storeys on sites that were previously limited to houses or duplexes, where the site sits within a set walking distance of a train station or a nominated town centre in an eligible council area.
