DCPs (Development Control Plans) NSW: how to read them for a residential project

TL;DR

Every residential DA in NSW is assessed against the council’s DCP as a mandatory head of consideration under s4.15 of the EP&A Act 1979. The DCP sits below the LEP and covers the design detail the LEP doesn’t: boundary setbacks, landscaping ratios, solar access, privacy, car parking, and stormwater. DCP controls are guidance, not statutory limits. Council cannot demand compliance if the applicant provides a well-reasoned argument for an alternative solution that still meets the control objectives. Pull the DCP alongside the LEP before design starts. CDC bypasses the local DCP entirely.

In plain English

A DCP (Development Control Plan) is a council-made planning document providing detailed design and siting guidance for development within a local government area. Each council in NSW has its own DCP.

DCPs sit below Local Environmental Plans (LEPs) in the planning hierarchy. The LEP sets the zone, the permissible land uses, and the key development standards (FSR, height of buildings). The DCP fills in the design detail the LEP doesn’t cover.

A DCP is not an environmental planning instrument (EPI) under the EP&A Act. LEPs and SEPPs are EPIs. DCPs are not. This means DCP provisions are guidance, not absolute requirements. Where an applicant cannot comply with a DCP control, the consent authority must apply flexibility and consider reasonable alternative solutions that achieve the objectives of that control.

DCPs are made under s3.43 of the Environmental Planning and Assessment Act 1979 (NSW) and prepared in accordance with Part 2 of the Environmental Planning and Assessment Regulation 2021 (NSW). Every council is required to publish its DCP on the NSW Planning Portal (verified 2026-05-09, planningportal.nsw.gov.au/DCP).

What it requires

Typical DCP controls for residential development

Control area	What the DCP typically sets
Boundary setbacks	Front, rear, and side setback minimums in metres. May vary by zone or lot width.
Landscaping ratio	Minimum percentage of lot area as landscaped or permeable surface.
Solar access	Minimum hours of direct sunlight to adjacent properties’ principal private open space.
Privacy and overlooking	Sill heights, screening, setbacks for elevated decks or windows overlooking neighbours.
Car parking	Number of spaces per dwelling type and garage setback from street boundary.
Stormwater and drainage	On-site detention requirements and roof drainage connection.
Heritage (where applicable)	Additional controls for conservation areas identified in the LEP.

Each DCP control set has objectives and controls. The objectives state what the rule is trying to achieve. The controls are the numerical or prescriptive requirement. When a proposal cannot meet the numerical control, the objectives are the basis for a departure argument.

What it doesn’t cover

DCPs do not cover:

Zoning and land use: set by the LEP. The DCP cannot permit a use the LEP prohibits.
FSR and height of buildings: numerical maxima are LEP development standards, requiring a formal cl 4.6 variation if breached. The DCP may add design rules within those limits but cannot change the LEP maximum.
SEPPs: State policies override LEPs and DCPs where inconsistent (EP&A Act s3.28). The Housing SEPP 2021, Codes SEPP, and Resilience and Hazards SEPP 2021 all operate above a local DCP.
Complying development (CDC): CDC is assessed against the Housing Code (Codes SEPP), not the local DCP. A CDC applicant does not need to satisfy DCP setback controls. This is a structural advantage of CDC over DA for standard residential work.

Practical implications

How to find your DCP

Go to the NSW Planning Portal DCP register. Every council is required to publish its DCP here.
Alternatively search your council’s website directly under “Development” or “Planning controls”.
Download the current version. DCPs are amended periodically. Check the amendment history on the first pages.
Confirm which DCP applies. Some councils have precinct-specific DCPs that apply in addition to the principal DCP.

DCP versus LEP: how strict is the control?

Control type	Instrument	Status	Non-compliance path
FSR (floor space ratio)	LEP cl 4.4	Statutory development standard	Clause 4.6 variation request required
Height of buildings	LEP cl 4.3	Statutory development standard	Clause 4.6 variation request required
Boundary setbacks	DCP	Guidance only	Good argument in the DA that objectives are met
Landscaping ratio	DCP	Guidance only	Good argument in the DA
Solar access	DCP	Guidance only	Good argument in the DA
Car parking	DCP	Guidance only	Good argument in the DA

Practical tips

Read the objectives, not just the controls. When you cannot comply with a numerical control, the objectives are what you argue against in the DA.
Use the pre-DA meeting. The pre-DA meeting is the right time to ask which DCP controls the council treats as non-negotiable versus which they regularly vary.
Rear setbacks and secondary dwellings. Many R2 zone DCPs require a 3 to 6 m rear setback. Secondary dwellings (granny flats) are governed by the Housing SEPP 2021, which sets its own setback rules and overrides the DCP for that use.
Solar access disputes. Councils treat solar access seriously in practice even though it is a DCP control. Shadow diagrams are typically required at DA lodgement.
Heritage precinct controls. Where a lot is in a heritage conservation area, the DCP heritage chapter controls materials, roof pitch, and window proportions. These are applied less flexibly than standard residential controls.
