Planning Risks Buyers Miss When Buying Property
2 January 2026
Recently, I worked with several buyers who were drawn to properties that looked exceptional on paper — great location, strong price growth, and seemingly high upside.
However, once we examined planning controls, transport corridors, and proposed future developments, it became clear that these properties carried significant long-term risks.
In one case, a highly attractive site was impacted by proposed increases in height and density under updated strategic planning controls aimed at addressing housing supply. In another, a first-home buyer was considering a property adjacent to un-rezoned land, exposing them to uncertainty around future development, amenity loss, and resale risk.
In both situations, we ultimately walked away from properties that appeared lucrative, because planning fundamentals did not support a stable, long-term outcome — especially for owner-occupiers.
This is why planning matters.
Understanding Planning and Zoning
Planning controls determine how land can be used, developed, and intensified over time. In Australia, zoning is administered by local councils under state legislation and typically includes residential, commercial, industrial, rural, and mixed-use zones.
Each zone is governed by rules covering:
Permitted land use
Building height and density
Floor space ratios (FSR)
Setbacks, lot sizes, and heritage or environmental overlays
These controls directly affect property value, future amenity, and development risk.
Impact on Property Value
Value Sensitivity to Planning Controls
Zoning restrictions and scarcity can significantly influence price
Uplifts or constraints caused by planning changes can materially affect value
Adjacent rezonings can be just as impactful as changes to the subject site
Investment and Resale Implications
Understanding planning helps buyers assess:
Whether growth is sustainable or speculative
If future supply may dilute value
How desirability may change over time
Development and Use Constraints
Permitted Uses
Zoning dictates whether land can be used for:
Residential living
Commercial or mixed-use activity
Higher-density housing or redevelopment
Built Form Controls
Planning instruments regulate:
Maximum building height
Density and dwelling yield
Building envelopes and typologies
Environmental and Heritage Overlays
Some sites are subject to:
Heritage conservation controls
Environmental protection zones
Flood, bushfire, or coastal constraints
These can significantly limit future works and increase compliance costs.
Lifestyle and Amenity Considerations
Planning doesn’t just affect value — it shapes how a place feels to live in.
Increased density can change noise, traffic, and privacy
Future infrastructure may bring convenience — or disruption
Commercial creep can erode residential character
Zoning exists to manage these outcomes, but changes can and do occur.
The Risk of Planning Changes
Strategic Planning and Master Plans
State and local governments regularly update:
Strategic plans
Housing supply targets
Transport and infrastructure corridors
Properties that sit within or near these areas may be affected years after purchase.
Rezoning and Adjacent Land Risk
Buying near un-rezoned or transitional land can expose buyers to:
Unpredictable future development
Loss of outlook, light, or privacy
Construction disruption and long approval timelines
This risk is particularly important for first-home buyers, where lifestyle stability matters.
Key Due Diligence Checks
When assessing a property, buyers should consider:
Local Environmental Plans (LEPs) and Development Control Plans (DCPs)
Zoning of both the subject site and surrounding land
Strategic planning documents and housing targets
Proposed transport or infrastructure projects
Title searches and planning certificates
In NSW, planning is governed under the Environmental Planning and Assessment Act 1979, with enforcement by local councils.
Final Thoughts
Planning controls are not a background detail — they are a core determinant of risk, value, and livability.
A property can look perfect today and still be compromised tomorrow if planning fundamentals are ignored. By understanding zoning, future development pathways, and strategic planning directions, buyers can make decisions that stand the test of time.
How We Help
As a buyers’ agency, we:
Flag planning and zoning risks early
Assess surrounding land and future development potential
Discourage purchases where planning risk outweighs upside
Recommend specialist advice from property lawyers or urban planners where required
Our role is not just to help you buy — but to help you avoid costly mistakes.
