First duplex in Penrith: LEP 2010 lot sizes and Torrens subdivision

A duplex (dual occupancy) investment in Penrith is governed by clause 4.1A of Penrith Local Environmental Plan 2010, which sets minimum lot sizes of 650 square metres for an attached dual occupancy and 750 square metres for a detached dual occupancy in the R2 Low Density Residential zone, and lower figures in R3. Whether the two dwellings can later be split onto separate Torrens titles is a different question, answered by the Lot Size Map under clause 4.1, the lot width rules in clause 4.1B and, near nominated centres, the low and mid-rise housing provisions of the Housing SEPP. Penrith Development Control Plan 2014 Part D2 Residential Development then sets the design controls. This guide is for investors looking at sites in Penrith, Kingswood, St Marys, Cambridge Park, Werrington, Emu Plains, Glenmore Park and Jordan Springs who need to know what the block can carry before they sign.

Who this is for: investors assessing a first duplex site in the Penrith local government area who want to test lot size, width, zoning and subdivision potential against Penrith LEP 2010 and DCP 2014 before purchase.

What lot size does Penrith LEP 2010 require for a dual occupancy?

Clause 4.1A Minimum lot sizes for dual occupancies, multi dwelling housing and residential flat buildings is the gateway control. Under subclause (2), consent may be granted to a dual occupancy only where the lot area equals or exceeds the figure in the table: in Zone R2, 650 square metres for a dual occupancy (attached) and 750 square metres for a dual occupancy (detached); in Zone R3, 550 square metres for an attached dual occupancy on a standard lot and 600 on a battle-axe lot, and 650 square metres for a detached dual occupancy on a standard lot and 700 on a battle-axe lot. Subclause (3) is the trap: despite any other provision of the plan, the council must not grant consent to a dual occupancy on a battle-axe lot in Zone R2.

Can a Penrith duplex be Torrens subdivided?

Two Torrens titles are worth more than a strata pair, and in Penrith the answer is often no. Penrith LEP 2010 contains no clause allowing the subdivision of a dual occupancy into lots smaller than the Lot Size Map minimum. Clause 4.1 applies the Lot Size Map to every subdivision, and clause 4.1B Minimum subdivision lot size for land in Zones R2 and R3 adds a width test: in R2 each resulting lot must be at least 15 metres wide (and, for a battle-axe lot, at least 650 square metres), and in R3 at least 12 metres wide (battle-axe lots 15 metres and 450 square metres). The clause does not apply to strata subdivision or to Glenmore Park Stage 3.

To Torrens subdivide a side-by-side duplex on a typical 700 square metre R2 lot, each half would need the Lot Size Map minimum and 15 metres of width, which a 20 metre frontage cannot deliver. The workable outcomes are a strata subdivision, which keeps one land title; a large R3 lot where each half meets the map minimum and 12 metres; or a site in a low and mid-rise housing area. Under Stage 2 of the Low and Mid-Rise Housing Policy, from 28 February 2025, Chapter 6 of State Environmental Planning Policy (Housing) 2021 applies non-refusal standards to dual occupancies within 800 metres walking distance of nominated centres and stations, including subdivision provisions that sit outside the LEP. Several Penrith centres and stations are nominated, and the NSW Planning Portal map is the only reliable way to confirm whether a lot is inside an area. Our subdivision planning service tests all three routes.

Which Penrith DCP 2014 controls shape the design?

Penrith DCP 2014 Part D2 Residential Development is the chapter. Section 2.1 sets the single dwelling controls and section 2.2 Dual Occupancies adds the specific ones in sections 2.2.2 to 2.2.22: preferred and alternative configuration, urban form, front and rear setbacks, building envelope and side setbacks, driveways and parking, landscaped area, solar planning, corner sites, garage design and fencing. The single dwelling controls in section 2.1.2, which the duplex controls build on, set the front setback at the greater of 5.5 metres or the average of the adjoining setbacks, a secondary street setback of 3 metres to walls and 5.5 metres to garage entrances, side setbacks of at least 900 mm, rear setbacks of 4 metres for single storey and 6 metres for two storey elements, and a building envelope drawn at 45 degrees from a set height above natural ground at the side boundaries. Garages and parking spaces are not permitted within the front setback other than stacked parking on a driveway, and section 2.2.15 requires at least one covered space where two are needed; confirm the numeric figures in sections 2.2.5 to 2.2.8 against the current Part D2, because a full DCP review is under way. Clause 5.21 of the LEP also applies along the Nepean, South Creek and Ropes Creek, where a flood report and raised floor levels are usually required.

What does Part C11 Subdivision add?

Where Torrens subdivision is achievable, Part C11 sets the allotment rules. Section 11.3.3 requires residential lots greater than 400 square metres to contain a building rectangle of 10 by 12 metres or 8 by 15 metres behind the building line; lots under 400 square metres attract special consideration of servicing, privacy and solar access. Battle-axe lots must exceed 400 square metres, with an access corridor at least 4 metres wide (5 metres if shared) and no longer than 60 metres. Section 11.3.2 prefers a 25 metre frontage where access is to a collector or major road and discourages long narrow and double-frontage lots.

Is the Low Rise Housing Diversity Code an option in Penrith?

Yes, where the numbers line up. Part 3B of State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 allows a dual occupancy (attached or detached) as complying development in the R1, R2, R3 and RU5 zones where the LEP permits dual occupancies, on a lot that meets the LEP’s minimum lot size for a dual occupancy (or 400 square metres where the LEP is silent), provided the land is not a heritage item or conservation area, is not reserved for a public purpose and is not otherwise excluded. In Penrith the clause 4.1A figure applies to the CDC as well: 650 or 750 square metres in R2. The code cannot vary a standard, and Torrens subdivision still depends on the LEP rules above.

A due diligence sequence before you buy

1. Confirm the zone and the Lot Size, Height of Buildings and Floor Space Ratio Map figures on the NSW Planning Portal, and whether the lot is inside a low and mid-rise housing area.
2. Measure the lot: area against clause 4.1A (650 or 750 square metres in R2), width at the building line against clause 4.1B (15 metres in R2, 12 metres in R3), and whether it is a battle-axe lot.
3. Obtain the section 10.7(2) and (5) certificate and read the flood, bushfire, contamination and heritage notations, then the title search for easements and section 88B restrictions.
4. Test the pathway: Low Rise Housing Diversity Code CDC if the lot size and exclusions allow, otherwise a DA with a statement of environmental effects against DCP 2014 Part D2 section 2.2.

Definitions

Dual occupancy (attached)

Two dwellings on one lot that are attached to each other, other than a secondary dwelling; the standard LEP term for a side-by-side or up-and-down duplex.

Dual occupancy (detached)

Two detached dwellings on one lot, other than a secondary dwelling; in Penrith it requires 750 square metres in R2 under clause 4.1A.

Battle-axe lot

A lot with an access handle to the street; excluded from dual occupancy development in Zone R2 by clause 4.1A(3) of Penrith LEP 2010.

Torrens title subdivision

Subdivision creating separate land titles for each dwelling, subject to the Lot Size Map and clause 4.1B width rules, as opposed to strata subdivision of a building on one land title.
