Council Approval for Dual Occupancy Development
A dual occupancy is two dwellings, attached or detached, on a single lot. Whether it is permitted, and what minimum lot size applies, depends on the zone and your council's LEP - there is no single statewide answer. Recent statewide housing reforms have broadened the zones in which dual occupancies can use the fast complying development pathway, so a site that needed a full DA a few years ago may now qualify for certification. We check the current position for your specific lot rather than relying on what used to apply.

Two dwellings, one lot, and a pathway that has been changing
Dual occupancy development sits in genuinely useful middle ground between a single house and higher-density housing types, and the rules around it have shifted meaningfully in recent years. Permissibility and minimum lot size still vary by zone and by council LEP - that part has not changed - but statewide housing reforms have opened the fast complying development pathway in more zones than before.
Why we check your specific site rather than quoting a general rule
Because the settings have moved, and because they differ between councils, a blanket answer about dual occupancies is not reliable. We confirm the current zone permissibility, minimum lot size and CDC eligibility for your address specifically, then match the design approach to whichever pathway actually applies.
Attached or detached
Both configurations are common. Attached dual occupancies bring shared-wall and acoustic separation requirements into play; detached versions are usually more sensitive to site coverage and landscaped area controls. We help you choose the configuration that fits your lot and your goals, then design to the pathway it needs to satisfy.

What we take off your hands
What EHUP handles
- Confirming permissibility and minimum lot size for your zone under the current LEP
- Checking whether recent housing reforms have opened the fast CDC pathway for your site
- Advising on attached versus detached configurations and what each requires
- Preparing and lodging the application, whichever pathway applies
- Coordinating subdivision strategy where you want to eventually separate the two lots
- Managing council or certifier queries through to determination
What you don't have to deal with
- Assuming your site is excluded from complying development based on outdated rules
- Planning to subdivide before confirming your council actually permits it for dual occupancies
Frequently asked questions
Has it become easier to build a dual occupancy in Sydney?
In many zones, yes. Statewide housing reforms have expanded where dual occupancies are permitted and where the fast complying development pathway is available, compared to the position a few years ago. Whether that applies to your specific lot still depends on the zone and your council's LEP, which is why we check it fresh rather than assuming.
What is the difference between this page and your CDC dual occupancy page?
This page covers the full decision - permissibility, lot size, and which pathway applies to your site, including cases that need a DA. Our CDC-specific page assumes the fast pathway already applies and details that process. Start here if you are not yet certain which one fits.
Can I subdivide a dual occupancy into two separate lots?
Sometimes, and it is a separate approval from the development consent for the dwellings themselves. Some councils permit Torrens subdivision of a dual occupancy and some do not, so this needs to be confirmed for your specific council before it is assumed achievable.
Does attached or detached make a difference to approval?
It can affect which controls apply, particularly around setbacks, shared walls and acoustic separation for attached configurations, and site coverage or landscaped area for detached ones. Both are common dual occupancy forms - the right choice depends on your lot shape and what you are trying to achieve.
Related services
CDC - Dual Occupancy
Dual occupancies - two dwellings on one lot, attached or detached - were traditionally assessed as a Development Application in most council areas.
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.
Torrens / Strata Subdivisions
Subdividing land into separate Torrens titles, or subdividing a building into separately owned strata lots - for example splitting an approved dual occupancy or multi dwelling development into individually owned lots - is a distinct approval from the development consent for the dwellings themselves.
