Council Rules for Subdividing Residential Blocks in Queensland

Understanding Council Subdivision Rules

Council planning schemes can seem impenetrable. This guide translates the key rules that affect residential block subdivision in South East Queensland into plain language.

The Planning Hierarchy

State Level: SEQ Regional Plan

The South East Queensland Regional Plan (ShapingSEQ) sets the overarching framework. It identifies where urban growth should occur and broadly categorises areas as:
- Urban footprint — where development is encouraged
- Rural living — limited subdivision potential
- Regional landscape — minimal development

If your property is within the urban footprint (most residential blocks in Brisbane, Logan, Gold Coast, Moreton Bay, Ipswich are), subdivision is generally possible subject to local council rules.

Local Level: Council Planning Schemes

Your local council's planning scheme contains the specific rules. The key documents are:
- Zoning map — determines what zone your property is in
- Overlay maps — identifies constraints like flooding, heritage, vegetation
- Zone codes — the detailed rules for each zone (minimum lot sizes, setbacks, height limits)
- Infrastructure charges schedule — what you pay per new lot

Zoning: The Most Important Factor

Your property's zone determines the minimum lot size and therefore whether subdivision is possible.

Brisbane City Council (City Plan 2014)

Zone Code	Zone Name	Min Lot Size	Min Frontage
LDR	Low Density Residential	400m²	10m
LMDR	Low-Medium Density Residential	300m²	10m
MDR	Medium Density Residential	No minimum	No minimum
CR	Character Residential	450m²	12m
EC	Emerging Community	Varies	Varies

Logan City Council

Zone	Min Lot Size	Min Frontage
Low Density Residential	400m²	12m
Low-Medium Density Residential	300m²	10m

Gold Coast City Council

Zone	Min Lot Size	Min Frontage
Low Density Residential	450m²	15m
Medium Density Residential	300m²	No minimum

Moreton Bay Regional Council

Zone	Min Lot Size	Min Frontage
General Residential	400m²	10m
Medium Density Residential	300m²	No minimum

Ipswich City Council

Zone	Min Lot Size
Low Density Residential	600m²
Medium Density Residential	400m²

Note: Ipswich has larger minimum lot sizes than other SEQ councils.

Overlays: The Hidden Restrictions

Even if your block meets the minimum lot size, overlays can restrict or modify what is possible:

Flood Overlay

If your block is in a flood-affected area, subdivision may still be possible but with conditions:
- Minimum floor levels for future dwellings
- Additional stormwater management requirements
- Possible reduction in developable area

Character Overlay (Brisbane)

Some Brisbane suburbs have character overlays that protect pre-1947 houses and streetscapes. In these areas:
- Minimum lot sizes may be larger (450m² vs 400m²)
- Building heights are restricted
- Existing character houses may need to be retained

Vegetation Protection Overlay

Significant trees or vegetation may restrict lot layout and building envelopes. You may need an arborist report and may not be able to remove protected trees.

Heritage Overlay

Properties on a heritage register have strict controls on demolition, alteration, and surrounding development. Heritage overlays significantly limit subdivision potential.

Infrastructure Charges

When you create a new lot, council charges an infrastructure contribution to fund roads, parks, water, and sewer. These charges vary significantly:

Council	Approx Charge Per New Lot
Brisbane City Council	$30,000-$45,000
Logan City Council	$25,000-$35,000
Gold Coast City Council	$28,000-$40,000
Moreton Bay Regional Council	$22,000-$35,000
Ipswich City Council	$20,000-$30,000

Infrastructure charges are a significant cost and should be confirmed with council before committing to subdivision.

The Assessment Process

Code Assessment

Most straightforward two-lot subdivisions are code assessable. This means:
- Assessment against measurable rules (lot size, frontage, access)
- No public notification
- No third-party appeal rights
- Decision within the statutory timeframe (typically 20-40 business days)

Impact Assessment

More complex subdivisions may trigger impact assessment:
- Public notification required (15-30 business days)
- Neighbours and public can make submissions
- Submissions can result in conditions or refusal
- Third-party appeal rights to the Planning and Environment Court

Common Triggers for Impact Assessment

• Creating 3+ lots
• Blocks in character or heritage zones
• Non-compliance with minimum lot size (requires variation)
• Environmental overlays

Tips for Navigating Council

1. Pre-lodgement meeting: Most councils offer free or low-cost pre-lodgement meetings where you can discuss your proposal informally. Take your planner.

2. Check the scheme yourself: Council planning schemes are available online. Spend 30 minutes checking your zoning and overlays before engaging professionals.

3. Information requests: Council may issue an information request during assessment, pausing the clock. Respond promptly and thoroughly.

4. Negotiating conditions: Infrastructure charges and some conditions can be negotiated. An experienced planner knows where flexibility exists.

5. Appeal rights: If your code assessable application is refused or conditioned unfairly, you can appeal to the Planning and Environment Court. This is rare for standard subdivisions.
