The Low- and Mid-Rise Housing Reforms: What They Mean for Your Sydney Block

If you own a residential block in Sydney, the planning rules that apply to it have changed twice in the last eighteen months. Most homeowners haven’t noticed — but the changes are quietly the most significant reshaping of NSW residential planning controls in a generation.

This post explains what the Low- and Mid-Rise Housing Policy reforms (LMR) actually do, where they apply, and what they mean for your block.

A Two-Stage Reform

The LMR Policy is being rolled out in two stages, both delivered through amendments to the State Environmental Planning Policy (Housing) 2021 (the Housing SEPP).

Stage 1 — commenced 1 July 2024

Stage 1 made dual occupancy and semi-detached dwellings permissible across virtually all R2 Low Density Residential zones in NSW — overriding councils that had previously excluded these dwelling types from R2 land. The minimum lot sizes and development standards continue to be set by each council’s LEP, but the use itself is now permissible everywhere R2 applies.

For owners in councils that had historically restricted dual occupancy to R3 Medium Density zones, or that had set minimum lot sizes of 700m² or higher, Stage 1 was a major opening up.

Stage 2 — commenced 28 February 2025

Stage 2 went much further. It introduced non-discretionary development standards for a range of dwelling types within 800m walking distance of 171 designated town centres and train/light rail stations across Greater Sydney, the Central Coast, the Illawarra, and the Hunter.

Within these mapped LMR Housing Areas, councils cannot impose more restrictive controls than the LMR standards. The standards are:

• Dual occupancy — R1/R2/R3/R4 zones, minimum 450m² and 12m wide, FSR 0.65:1, height 9.5m. Subdivision permitted to 225m² per lot, 6m wide.
• Manor houses (3–4 dwellings) — R1/R2/R3/R4 zones, minimum 600m² and 12m wide, FSR 0.7:1, height 9.5m. Looks like a single large house from the street.
• Terraces (3+ dwellings) — R1/R2/R3/R4 zones, minimum 500m² and 18m wide, FSR 0.7:1, height 9.5m. Subdivision permitted to 165m² per lot, 6m wide.
• Small residential flat buildings — R1/R2 zones, minimum 500m² and 12m wide, FSR 0.8:1, height 9.5m.
• Larger residential flat buildings — R3/R4 zones within 400m of a station or centre, FSR 2.2:1, height 22m, up to 6 storeys. R3/R4 zones within 400–800m, FSR 1.5:1, lower height. For blocks outside the mapped 800m catchments, the Stage 1 reforms still apply — dual occupancy is permissible in R2 zones across the State — but the specific lot size and width thresholds revert to the council’s LEP controls.

How to Check If Your Block Is Affected

The NSW Government has published an interactive map showing the 171 designated centres and their 800m walkable catchments. You can find this on the NSW Department of Planning, Housing and Infrastructure website by searching “Low and Mid-Rise Housing Indicative Map”.

The map measures the catchment as walking distance along pedestrian routes, not as a straight-line radius. A block that is 600m as the crow flies from a station may be more than 800m by foot if there’s no direct walking route. The walkable measurement is the one that determines LMR eligibility.

A few practical notes:

• The map is “indicative” — final eligibility is confirmed on a site-specific basis at the time of application.
• The catchments include parts of Heritage Conservation Areas (HCAs), where LMR applies but with council assessment. Individually heritage-listed properties are excluded.
• Bushfire-prone land, coastal wetlands, land near dangerous goods pipelines, and land subject to high aircraft noise are also excluded.

What’s the Approval Pathway?

LMR is predominantly a DA-based reform — the non-discretionary standards apply to applications assessed by council under a Development Application. The DA pathway exists because LMR was designed to coexist with council-administered controls on parking, landscaping, design quality, and streetscape.

A few exceptions exist. The NSW Housing Pattern Book — released progressively from July 2025 — provides a Complying Development pathway for sites that use an endorsed Pattern Book design and meet the relevant criteria. For some site configurations, this is significantly faster than the standard DA pathway.

Outside LMR areas, the standard Codes SEPP CDC pathway continues to apply for compliant single dwellings, secondary dwellings, and other low-rise developments.

What This Means for Different Types of Block

A 600m²+ block in an R2 zone, inside an LMR catchment

This is the sweet spot. A dual occupancy is permissible (450m² minimum, you exceed it). A manor house is permissible (600m² minimum, you may meet it). Subdivision is permitted to 225m² per lot. The maximum FSR of 0.65:1 means a 600m² block can carry approximately 390m² of total floor area — typically two 195m² dwellings, or one configuration of three or four manor-house units.

For owners of these blocks, LMR has materially increased the development potential. The block that was a single-dwelling site three years ago is now a dual-occupancy, manor-house, or potentially terrace site.

A 12–15m wide block in an R2 zone, inside an LMR catchment

The Stage 2 minimum width of 12m is the key threshold. Many narrow blocks across older Sydney suburbs sit between 12m and 15m wide and were previously locked out of dual occupancy by council width minimums of 15m, 18m, or even higher. LMR has opened these sites up to dual occupancy at the 12m minimum.

A block outside the 800m catchment

The Stage 1 reforms still apply. Dual occupancy is permissible in R2 zones, subject to the council’s LEP minimum lot size. The Stage 2 non-discretionary standards (450m² minimum, 0.65 FSR, 9.5m height) don’t apply — you’re back to the council’s own LEP and DCP controls, which are typically more restrictive.

A block in a Heritage Conservation Area, inside an LMR catchment

LMR applies, but the development is subject to council assessment of heritage impacts. The non-discretionary numerical standards still apply, but the design will need to be sympathetic to the heritage character of the area. This is a more nuanced pathway than non-HCA sites and requires careful design.

A block in a Heritage Conservation Area, with the property itself heritage-listed

LMR does not apply. The property is excluded. Any development is assessed against the standard heritage controls through a Development Application.

A block on bushfire-prone land

Excluded from the LMR Pattern Book CDC pathway. LMR DA-assessed development may still be possible depending on the BAL rating and the planning controls that apply, but the CDC pathway is closed.

The Catch: It’s Still a DA in Most Cases

LMR has opened up what’s permissible, but it hasn’t necessarily made approval easier in absolute terms. Most LMR developments are assessed through a Development Application, which means:

• Statement of Environmental Effects
• Shadow diagrams
• Streetscape analysis
• Landscape plan
• Stormwater design
• Possibly an arborist report, heritage impact assessment, or traffic statement depending on the site
• Council assessment timeframes of 3–6 months for a typical dual occupancy DA, longer for manor houses and small RFBs The non-discretionary standards give certainty on FSR, height, and lot size — but they don’t override the need for thorough design and documentation, and they don’t shortcut the assessment process unless the project uses a Pattern Book design eligible for CDC.

What This Means If You’re Sitting on a Suitable Block

The LMR reforms have created a generational shift in what’s permissible on a large proportion of Sydney’s residential land. Combined with the federal budget changes that favour new builds for negative gearing and depreciation, the policy environment is now structurally aligned to encourage owner-led duplex, manor-house, and small-multi-dwelling development.

If your block meets the LMR criteria — appropriate zone, sufficient lot size and width, located inside a mapped catchment — the question worth asking is whether the policy alignment makes the project economically viable for your specific circumstances. The answer isn’t always yes. Construction costs in Sydney are high, finance is expensive, and the development feasibility on any specific block depends on the relationship between land value, build cost, and end value.

But for many blocks where the answer was “no” three years ago, the answer is now “let’s run the numbers”.

Where Plan Land Comes In

We assess every block we work on against LMR Stage 1, Stage 2, the Pattern Book pathway, and the underlying LEP/DCP controls — and we tell our clients honestly which pathway delivers the best outcome for their specific site. In some cases, LMR opens up genuine new development potential. In others, the standard LEP/DCP controls remain the better fit.

The first step is always a feasibility assessment. We map the controls, run the numbers, and tell you whether the block is worth developing — or whether holding and waiting is the better call.
