NSW Low and Mid-Rise Housing Reform: What It Means for Homebuilders (2026)

NSW Low and Mid-Rise Housing Reform: The Biggest Planning Change in a Generation

In September 2023, the NSW Government announced the Low and Mid-Rise Housing Policy — the most significant residential planning reform in New South Wales in over 30 years. The policy, which progressively takes effect from July 2024 through 2025–2026, fundamentally changes what you can build on residential land within 800 metres of key transport nodes and town centres.

The reform creates a new State Environmental Planning Policy (SEPP) that overrides local council planning controls, allowing duplexes, terraces, manor houses, and low-rise apartment buildings (up to 6 storeys) in areas previously restricted to single houses.

For homeowners, developers, and builders in Western Sydney — particularly across the five key LGAs of Fairfield, Liverpool, Cumberland, Canterbury-Bankstown, and Blacktown — this reform unlocks enormous development potential on sites that were previously limited to single dwellings.

This guide explains what the reform means, which areas are affected, what you can build, and how to take advantage of the new rules in 2026.

What Are the New Rules? Types of Housing Now Permitted

The reform introduces four housing typologies that can now be built on residential land near transport and town centres, overriding previous council restrictions:

**1. Dual Occupancies (Duplexes) — within 800m of transport/centres** • Permitted on R2 Low Density Residential zones (previously many councils blocked duplexes in R2) • Minimum lot size: 450sqm (down from 600–700sqm in most councils) • Maximum height: 9.5m (2 storeys) • Maximum FSR: 0.65:1 • Each dwelling must be at least 60sqm internal area • Private open space: 24sqm per dwelling • Must comply with BASIX energy and water targets

**2. Manor Houses (3–4 dwellings) — within 800m of transport/centres** • Permitted on R2 zones (completely new for most of Sydney) • Minimum lot size: 600sqm • Maximum height: 9.5m (2 storeys) • Maximum FSR: 0.7:1 • Appears as a single large house from the street • 3 or 4 self-contained dwellings inside • Each dwelling must be at least 50sqm • No more than 2 dwellings at ground level, 2 at first floor

**3. Terraces (3+ attached dwellings) — within 800m of transport/centres** • Permitted in R2 zones (new for most of Sydney) • Minimum lot size: 200sqm per dwelling • Maximum height: 9.5m • Maximum FSR: 0.7:1 • Minimum 3 dwellings, row-house format • Each dwelling must have direct street or lane access • Minimum dwelling size: 60sqm for 1-bed, 80sqm for 2-bed, 100sqm for 3-bed

**4. Low-Rise Apartment Buildings (up to 6 storeys) — within 400m of transport only** • Permitted in R2 and R3 zones (completely new for R2) • Minimum lot size: 1,000sqm • Maximum height: 21m (6 storeys) • Maximum FSR: up to 2.5:1 • Minimum 10% affordable housing contribution • Must comply with Apartment Design Guide • Design excellence panel review required

**Key dates:** • July 1, 2024: Dual occupancies and manor houses enabled in initial tranche of councils • December 2024: Terraces and apartments enabled • 2025–2026: Full rollout across all metropolitan Sydney councils • Transition provisions apply — DAs lodged under old rules before the SEPP commencement are assessed under old controls

Which Areas Are Affected in Western Sydney's Five LGAs?

The reform targets land within 800 metres walking distance (not straight line) of specified train stations, Metro stations, and town centres. Here's how it affects each of the five key Western Sydney LGAs:

**Fairfield LGA:** • Affected stations: Fairfield, Canley Vale, Cabramatta, Carramar, Villawood, Yennora • Estimated R2 land unlocked for duplexes: 8,000–12,000 lots • Town centres affected: Fairfield CBD, Cabramatta CBD, Canley Heights village • Key opportunity suburbs: Fairfield, Cabramatta, Canley Vale, Carramar, Villawood • Council response: Fairfield City Council initially opposed the reform but is now preparing local character statements. Heritage protections around Cabramatta remain

**Liverpool LGA:** • Affected stations: Liverpool, Warwick Farm, Casula, Holsworthy, Edmondson Park, Leppington • Estimated R2 land unlocked: 10,000–15,000 lots • Town centres affected: Liverpool CBD, Moorebank town centre, Casula Mall area • Key opportunity suburbs: Liverpool (around station), Warwick Farm, Casula, Holsworthy, Moorebank • Western Sydney Airport effect: Additional TOD precincts planned around Aerotropolis

**Cumberland LGA:** • Affected stations: Auburn, Lidcombe, Berala, Regents Park, Granville, Merrylands, Guildford, Yennora, Wentworthville, Westmead • Estimated R2 land unlocked: 12,000–18,000 lots (highest density of stations) • Key opportunity suburbs: Merrylands, Guildford, Granville, Auburn, Lidcombe, Berala • Heritage constraint: Parts of Granville have heritage conservation areas limiting reform application • Cumberland has the HIGHEST number of train stations of any Western Sydney LGA — creating the most reform-affected land

**Canterbury-Bankstown LGA:** • Affected stations: Bankstown, Punchbowl, Wiley Park, Lakemba, Belmore, Campsie, Canterbury, Hurlstone Park (all converting to Metro) • Estimated R2 land unlocked: 15,000–20,000 lots • Double effect: Both the housing reform SEPP AND the Metro TOD SEPP apply • Key opportunity suburbs: Bankstown, Campsie, Canterbury, Belmore, Lakemba, Revesby, Padstow, Panania • This LGA benefits more than any other from the combined effect of BOTH reforms

**Blacktown LGA:** • Affected stations: Blacktown, Seven Hills, Toongabbie, Doonside, Rooty Hill, Mount Druitt, St Marys, Marayong • Estimated R2 land unlocked: 15,000–20,000 lots • Town centres affected: Blacktown CBD, Mount Druitt centre, St Marys • Key opportunity suburbs: Blacktown, Seven Hills, Toongabbie, Marayong, St Marys • New Metro Western Sydney Airport line creates additional TOD precincts around St Marys

**Total estimated R2 lots unlocked across 5 LGAs: 60,000–85,000 lots** This represents an enormous potential pipeline of duplex, manor house, and terrace development — far more than any previous planning reform in Sydney's history.

Financial Impact: What the Reform Means for Land Values and Development Feasibility

The housing reform creates a direct uplift in land value for affected properties. Research by property economics consultancy Atlas Economics estimates that R2 land gaining duplex/manor house development rights within 800m of a station typically increases in value by 15–40%, depending on lot size and frontage.

**Land value impact by lot size:** • 450–500sqm lot gaining duplex rights: +15–25% land value uplift • 600–700sqm lot gaining manor house rights: +25–35% uplift • 800–1,000sqm+ lot gaining terrace rights: +30–40% uplift • 1,000sqm+ lot gaining apartment rights: +40–100%+ uplift

**Development feasibility example — duplex on newly eligible R2 lot:** Scenario: 550sqm R2 lot in Merrylands (Cumberland), 600m from station • Current land value (single house): $900,000 • Post-reform land value (duplex potential): $1,100,000 (+22%) • Existing house value: $120,000 (to be demolished) • Demolition cost: $25,000 • Duplex construction (2 x 3-bed, 130sqm each): $750,000 • DA, subdivisions, fees: $40,000 • Total project cost: $1,915,000 • End value (2 x 3-bed townhouse-style duplexes): $2,400,000 • Gross profit: $485,000 • Return on cost: 25.3%

**Development feasibility example — manor house:** Scenario: 700sqm R2 lot in Bankstown, 500m from metro station • Current land value: $1,000,000 • Post-reform value (manor house potential): $1,350,000 • Demolition: $30,000 • Manor house construction (4 x 2-bed, 80sqm each): $1,100,000 • DA, fees, contributions: $60,000 • Total project cost: $2,540,000 • End value (4 x 2-bed dwellings): $3,200,000 • Gross profit: $660,000 • Return on cost: 26.0%

**Important:** These feasibilities assume current construction costs and Q1 2026 end values. The market is moving — both land values (up) and construction costs (stabilising after 2022–2024 inflation). Early movers capture the development margin before land prices fully reflect the new zoning rights.

How to Take Advantage of the Reform: Practical Steps for 2026

Whether you own a property in an affected area or you're looking to buy one, here's how to capitalise on the reform:

**Step 1 — Check if your property qualifies:** • Use the NSW Planning Portal's interactive map (planningportal.nsw.gov.au) to check if your property is within the 800m walking catchment • Verify your zoning — R2 Low Density Residential is the key target zone • Check lot size — 450sqm+ for duplex, 600sqm+ for manor house, 200sqm per dwelling for terraces • Identify any constraints — heritage conservation areas, flood-prone land, bushfire-prone land, or contaminated sites may limit application

**Step 2 — Understand what you can build:** • On a 450–599sqm lot: Duplex (2 dwellings) is your option • On a 600–799sqm lot: Manor house (3–4 dwellings) or duplex • On an 800–999sqm lot: Terraces or manor house • On a 1,000sqm+ lot within 400m: Low-rise apartments may be feasible

**Step 3 — Get a feasibility assessment:** • Engage a builder with planning experience to assess your site • Key inputs: lot dimensions, slope, orientation, existing services, tree canopy, neighbour context • A good feasibility will model 2–3 development scenarios with cost estimates and projected end values

**Step 4 — Decide on approval pathway:** • CDC (Complying Development Certificate): Faster (4–6 weeks), but design must strictly comply with the SEPP provisions. No neighbour notification • DA (Development Application): More flexible design, but longer (3–6 months). Neighbour notification and potential objections. Required for heritage areas, flood-prone land, or sites near heritage items

**Step 5 — Engage the right team:** • Builder: Choose a builder experienced in medium density — not a volume builder who only does project homes • Architect/designer: Must understand the SEPP provisions and be experienced in duplex/manor house design • Town planner: Recommended for DA pathway, especially if the site has constraints • Surveyor: Required for subdivision (Torrens or strata)

**Common mistakes to avoid:** • Buying land outside the 800m walking catchment (straight-line distance is different to walking distance) • Assuming old council rules still apply — the SEPP overrides local LEP and DCP provisions • Over-capitalising on finishes when the market is price-sensitive • Not accounting for infrastructure contributions (Section 7.11) which can be $20,000–$40,000 per dwelling • Ignoring site constraints like sewer easements, power easements, or overland flow paths
