LEP and DCP in NSW: What Property Developers Need to Know

Finding a property with the right zoning is not the same as finding a good development site.

For property developers in NSW, that distinction can be worth hundreds of thousands of dollars.

A site might have attractive zoning, suitable land area and strong surrounding development. The selling agent may even promote it as having significant “development potential”.

But once you start investigating the planning controls properly, the picture can change.

Floor Space Ratio (FSR), maximum building height, setbacks, landscaping, parking, access, stormwater, heritage, flooding and other constraints can all influence what can realistically be achieved.

That is why understanding the LEP and DCP in NSW, together with relevant State Environmental Planning Policies (SEPPs), should be part of your due diligence before acquiring a development site.

Because the most important question isn't:

“What is this property zoned?”

It is:

“What can I realistically develop here, and does it still make financial sense?”

Understanding the NSW Planning System

Before looking at the difference between an LEP and DCP, developers need to understand where these documents sit within the NSW planning framework.

The Environmental Planning and Assessment Act 1979 (NSW) provides the legislative foundation for much of the NSW planning and development assessment system.

Within that framework are Environmental Planning Instruments (EPIs), which include:

• State Environmental Planning Policies (SEPPs)

• Local Environmental Plans (LEPs)

Development Control Plans (DCPs) sit differently within the system. They provide detailed local planning and design guidance but are not themselves environmental planning instruments.

For a property developer, understanding this hierarchy matters because the different planning documents do not all carry the same legal status or operate in the same way.

What Is a SEPP in NSW?

A State Environmental Planning Policy, commonly known as a SEPP, deals with planning matters at a NSW Government level.

SEPPs can apply across the state or address particular development types, locations, planning issues and policy objectives.

Depending on the development, they can affect areas such as housing, infrastructure, transport, biodiversity, hazards, employment land and exempt and complying development.

This means checking the council's LEP alone may not provide the complete planning picture.

A relevant SEPP can introduce additional provisions that affect what can be developed and how a proposal is assessed.

For developers conducting site due diligence, the first lesson is therefore simple:

Don't stop your planning investigation at the local zoning map.

Know the controls before you buy the site.

What Is a Local Environmental Plan (LEP)?

A Local Environmental Plan (LEP) is an environmental planning instrument that establishes important local planning controls.

One of the first things a developer will usually investigate is the site's land-use zoning.

The relevant zone establishes objectives and identifies development that may be permitted with or without consent and development that is prohibited.

Depending on the particular LEP and property, developers may also need to investigate provisions relating to:

• Maximum building height

• Floor Space Ratio (FSR)

• Minimum subdivision lot size

• Heritage

• Additional permitted uses

• Acid sulfate soils

• Biodiversity

• Environmental considerations

• Other mapped or site-specific provisions

The LEP therefore helps establish the statutory framework within which the development opportunity needs to be considered.

But this is where developers need to be careful. Permissible does not necessarily mean achievable.

A development type may be permissible on the land while the site itself cannot comfortably accommodate the yield required to make the project financially viable.

What Is a Development Control Plan (DCP)?

A Development Control Plan (DCP) generally provides the more detailed planning and design guidance used to shape development within a particular council area.

Where an LEP establishes key statutory planning parameters, a DCP can get much deeper into how the development should actually function and respond to its surroundings.

Depending on the council and development type, a DCP may contain controls dealing with:

• Front, side and rear setbacks

• Building form and articulation

• Landscaping and deep-soil areas

• Site coverage

• Private open space

• Car parking

• Driveway design

• Solar access

• Overshadowing

• Privacy

• Waste management

• Stormwater

• Streetscape and local character

And because DCPs are developed at the council level, requirements can vary considerably between different local government areas.

A design that works on one site may therefore require a substantially different approach only a few suburbs away.

LEP vs DCP: What Is the Difference?

For developers, a useful way to understand the difference is:

The LEP establishes important statutory controls around what may be developed and the parameters applying to the land.

The DCP provides more detailed guidance around how that development should be designed and delivered.

An LEP is an environmental planning instrument with statutory force.

A DCP is not an environmental planning instrument and operates differently. Its provisions provide detailed guidance and are intended to assist in achieving the objectives of the applicable planning framework.

There can therefore be greater flexibility in dealing with a DCP control where an alternative design response can appropriately achieve the relevant objectives.

However, developers should not interpret that flexibility as meaning:

“We don't need to worry about the DCP.”

You absolutely do.

Significant DCP departures can influence design, assessment, consultant work, council negotiations, approval risk and project timing.

The smarter approach is to identify those issues before buying the land.

Don’t rely on zoning alone.

Zoning Doesn't Guarantee Your Development Yield

This is where planning controls start becoming financial controls.

Imagine you are assessing a 1,200m² site.

The proposed residential development is permissible, and your preliminary calculations suggest six dwellings could work.

Your feasibility therefore assumes six completed sales.

Then the concept design begins.

Setbacks reduce the building footprint.

Landscaping and deep-soil requirements consume more site area.

Vehicle access and manoeuvring affect the layout.

Private open space needs to be accommodated.

Stormwater infrastructure takes additional space.

An existing tree complicates the design.

Six dwellings become five.

Perhaps five becomes four.

Nothing has changed about the zoning.

But almost everything has changed about your feasibility.

That is why experienced developers distinguish between theoretical development potential and realistically achievable yield.

Don't Treat FSR as Guaranteed Floor Area

Floor Space Ratio is another area where preliminary development assessments can become misleading.

A developer may look at the applicable FSR, multiply it by the site area and assume that amount of Gross Floor Area can be achieved.

But FSR is only one part of the equation.

You still need to design a building that responds appropriately to height, setbacks, landscaping, access, parking, building separation, amenity and other applicable requirements.

You may have a theoretical FSR available that cannot practically fit within the site's realistic development envelope.

Alternatively, the physical envelope may appear capable of accommodating additional floor area while the applicable FSR limits how much can actually be developed.

The number that matters isn't simply the maximum FSR. It's the amount of commercially useful floor area you can realistically deliver.

The LEP and DCP Are Only Part of Your Due Diligence

A proper NSW development site assessment should extend beyond the LEP and DCP.

Depending on the property, developers may also need to investigate:

Flooding, bushfire, heritage, biodiversity, contamination, easements, significant vegetation, acid sulfate soils, traffic, vehicle access, stormwater, utilities and infrastructure capacity.

None of these necessarily means a development should be abandoned.

But they can affect:

Yield. Design. Cost. Time. Approval risk.

And all of those eventually affect your development margin.

This is why planning due diligence and financial feasibility should never operate independently.

Every material planning constraint should eventually find its way back into the numbers.

Check the planning. Test the feasibility. Then commit.

Can a Development Depart From the DCP?

Depending on the circumstances, a proposal may seek an alternative response to a DCP control.

DCP provisions are not applied in precisely the same way as statutory development standards contained within an environmental planning instrument.

Where an alternative solution achieves the relevant planning and design objectives, there may be scope for flexibility.

But there is a major difference between having a defensible planning strategy and simply assuming council will accept non-compliance.

If your development feasibility only works because you need multiple substantial DCP departures to achieve the required yield, that should be treated as a development risk.

Don't make optimistic planning assumptions, do the heavy lifting in your feasibility.

What About a Clause 4.6 Variation?

A Clause 4.6 variation request is different from a proposed DCP departure.

Clause 4.6 can provide a mechanism for seeking flexibility from certain development standards contained within an applicable environmental planning instrument, subject to the relevant statutory requirements.

A properly prepared request needs to justify the proposed contravention on planning grounds. Not every development standard is necessarily capable of being varied through Clause 4.6.

For developers, the important commercial point is this:

Don't treat a Clause 4.6 variation as guaranteed additional development potential.

If the profitability of a site depends on exceeding a statutory development standard, investigate the planning risk before determining what you are prepared to pay for the land.

Beware of Those Four Letters: STCA

Property advertisements regularly promote sites as:

“Duplex potential – STCA.”

“Ideal townhouse development – STCA.”

“Development opportunity – STCA.”

STCA means Subject to Council Approval.

For a developer, those four letters should trigger further investigation, not greater confidence.

The agent is marketing the property. You are responsible for determining its development potential.

Before paying a premium for land because of its supposed development upside, independently test the planning controls, constraints, preliminary design and feasibility.

A marketing description is not a town planning assessment.

And it certainly isn't a development feasibility.

Found a development site? Let’s test its real potential.

LEP and DCP Controls Can Change What the Site Is Worth

This is where planning due diligence becomes particularly important commercially.

Assume your initial feasibility is based on six townhouses.

After detailed planning and preliminary design investigations, the realistic yield becomes five.

You have not simply lost one dwelling.

You may have lost hundreds of thousands of dollars in potential revenue while much of the land cost, consultant expenditure, finance, holding costs and development overhead remain.

The residual land value can therefore change dramatically. This is why we believe developers should work backwards.

Establish a realistic development outcome.

Estimate the end value.

Understand construction and development costs.

Allow for finance, contingency, risk and the required development margin.

Then determine what the site is worth to you.

Trying to make the development fit a land price you have already committed to is the wrong way around.

How OwnerDeveloper Approaches NSW Planning Due Diligence

At OwnerDeveloper, this isn't simply a process we recommend to clients.

It is a methodology we use on our own private development projects and teach to other property developers.

When assessing an opportunity, we want to understand the relevant SEPP, LEP and DCP controls as early as possible, together with the physical, environmental and infrastructure constraints affecting the site.

Where appropriate, that means bringing together the relevant town planning, architectural, engineering and other specialist advice and testing it through a preliminary concept and development feasibility.

We aren't simply trying to answer:

“Can we develop this property?”

We want to know:

• What can realistically be developed?

• What is the achievable yield?

• What controls or constraints could reduce that yield?

• Are planning variations likely to be required?

• What is the probable approval pathway?

• What could increase our development costs or timeframe?

• What risks need to be reflected in the feasibility?

• Does the opportunity still produce an acceptable commercial return?

Because obtaining development approval is an important milestone.

But an approved development that doesn't financially stack up isn't a successful development.

Understand what you can build before you buy.

Final Thoughts

Understanding the LEP and DCP in NSW should be part of your site investigation before you become financially committed to the land

Check the relevant State planning policies.

Understand the zoning.

Review the LEP.

Investigate height, FSR and other relevant development standards.

Then work through the DCP controls affecting setbacks, landscaping, parking, access, amenity and building design.

Look beyond the planning documents to the physical and environmental constraints affecting the site.

Then test everything against a realistic concept design and development feasibility.

Because the zoning might tell you that development is possible.

But proper due diligence tells you whether the development you actually want to build is realistic, approvable and commercially worthwhile.

Frequently Asked Questions

What is the difference between an LEP and DCP in NSW?

A Local Environmental Plan (LEP) is an environmental planning instrument that establishes statutory controls such as zoning, building height, Floor Space Ratio (FSR) and minimum lot size. A Development Control Plan (DCP) provides more detailed local guidance covering matters such as setbacks, landscaping, parking, privacy and building design.

Does complying with the LEP mean my development will be approved?

No. LEP compliance is only part of the assessment. Your development may also need to address relevant SEPPs, DCP controls, site constraints and other planning requirements before development consent can be granted.

Can a development vary from a DCP in NSW?

Potentially. DCP provisions are not statutory development standards in the same way as LEP controls and are intended to be applied with appropriate flexibility. A proposed departure should generally demonstrate how the alternative design satisfactorily achieves the relevant objectives.

What is a Clause 4.6 variation?

Clause 4.6 provides a mechanism for requesting flexibility from certain development standards contained in an environmental planning instrument. It requires appropriate planning justification and should never be assumed to guarantee additional height, FSR or development yield.

Why should developers review the LEP and DCP before buying land?

Because zoning alone does not determine the site's realistic development yield. LEP and DCP controls, together with site constraints, can affect building area, dwelling numbers, design, approval risk, construction costs and ultimately the amount a developer should be prepared to pay for the land.
