Undertaking renovations or building work on your home can be an exciting journey—but before the first nail is hammered, it’s crucial to understand the local planning laws and whether you need council approval.
If you’re a homeowner in Sydney, navigating the council approval process can seem complex and time-consuming. This guide breaks it all down—what type of development you’re undertaking, whether you need approval, how to apply, and who can help. Whether you’re installing a pool, converting a garage, building a granny flat, or extending your home, this guide is designed to help you avoid common pitfalls.
Understanding Development Categories
In New South Wales, residential construction and renovation projects typically fall into one of three categories:
1. Exempt Development – No Approval Required
Exempt developments are small-scale, low-impact projects that don’t require any approval, provided they meet certain standards. These are straightforward works that generally do not affect neighbours or the environment.
Examples of exempt development:
- Installing a pergola or carport under a certain size
- Replacing windows and doors
- Building a small garden shed
- Erecting a fence within height limits
- Painting and internal cosmetic updates
To qualify, your project must comply strictly with the NSW Exempt and Complying Development SEPP guidelines. If your work exceeds the specified size or height, or your property is heritage-listed, you’ll need to follow another process.
2. Complying Development – Fast-Tracked Approval
Complying development sits between exempt development and a full development application. It’s a fast-tracked approval process, typically taking 10 days, and can be used for work that has more significant impacts but still meets pre-set planning criteria.
Common examples include:
- Building a granny flat
- Alterations and additions to existing homes
- Demolishing a building
- Swimming pools
- Some two-storey homes
You can apply through a Private Certifier or the local council, and your project must comply with the applicable Complying Development Codes.
3. Development Application (DA) – Full Council Assessment
A Development Application (DA) is required for any proposal that does not meet the requirements for exempt or complying development. The DA process is more detailed and time-consuming, involving assessment by your local council’s planning team.
Situations where a DA is usually needed:
- Properties that are heritage-listed or in conservation zones
- Large home extensions
- New builds that don’t meet code standards
- Building on flood-prone or bushfire-prone land
- Dual occupancy projects or subdivisions
In some cases, you may also need a Construction Certificate (CC) after DA approval, to certify that the construction plans comply with the Building Code of Australia.
What Documents Are Required for a DA?
When lodging a DA, you’ll need to provide a comprehensive set of documents. Depending on the scope of work and the location of your property, the exact requirements may vary, but generally include:
- Architectural plans: floor plans, elevations, and sections
- Statement of Environmental Effects (SEE): outlines how the development impacts the environment and how you’ll mitigate any adverse effects
- BASIX certificate: for sustainability compliance (energy and water efficiency)
- Site plan and survey: showing boundaries, levels, and any existing structures
- Shadow diagrams: if your project impacts sunlight on neighbouring properties
- Stormwater drainage plans
- Heritage impact statements, bushfire risk assessments, or flood studies (if applicable)
These documents must be prepared by qualified professionals and submitted through the NSW Planning Portal.
Understanding Zoning, LEPs, and DCPs
Before you plan any major changes, you’ll need to understand the zoning of your property and how it fits within your council’s planning framework. This includes:
- Local Environmental Plan (LEP) – A statutory plan that controls land use and development types in the area.
- Development Control Plan (DCP) – A non-statutory document that provides additional design and planning guidelines.
These documents regulate:
- Minimum lot sizes
- Building height limits
- Floor space ratios
- Setbacks and open space requirements
- Landscaping
- Parking provisions
You can find this information on your local council’s website or by using the NSW Planning Portal.
The Approval Timeline
Understanding how long approvals take is critical to project planning. Here’s a rough guide:
- Exempt Development: No waiting time – you can start immediately (as long as criteria are met).
- Complying Development: Approximately 7–10 business days from submission (if documentation is correct).
- Development Application: Varies widely, usually between 6 to 12 weeks, but may take longer if revisions, neighbour objections, or council delays occur.
Some councils also offer pre-lodgement meetings, which can help identify issues early and reduce delays.
Community Consultation and Notification
When you submit a DA, your local council may notify neighbours or the broader community, depending on the scale of the project. This public notification period allows residents to raise concerns or objections.
Common concerns from neighbours may include:
- Loss of sunlight or privacy
- Increased traffic or noise
- Visual bulk and overshadowing
If objections are received, the application might be sent to an internal planning panel or independent review panel, which could result in requested changes to your plans.
Professionals You May Need
The approval process can be complex, so many Sydney homeowners engage qualified professionals to streamline the journey.
Common professionals involved include:
- Architects: For design and documentation
- Draftspersons: For technical drawing (lower cost than architects)
- Town planners: For advice on compliance and planning strategies
- Private certifiers: For Complying Development approvals and construction certification
- Engineers: For structural, stormwater, or geotechnical reports
- Bushfire/flood consultants: If your site is in a hazard-prone area
Hiring the right team early can save time, reduce the risk of rejection, and ensure smoother communication with council.
Using the NSW Planning Portal
Since 2020, the NSW Planning Portal has become the central online platform for all development applications across the state. You can use the portal to:
- Lodge Development Applications (DA) or Complying Development Certificates (CDC)
- Track your application’s progress
- Check zoning and planning controls for your property
- Access templates and forms

Common Mistakes to Avoid
Many homeowners run into delays and issues because of avoidable mistakes. Here’s how to stay on track:
- Failing to check zoning and property constraints early
- Submitting incomplete or inaccurate documentation
- Assuming council approval is optional for certain works
- Not engaging qualified professionals to help with plans and compliance
- Beginning construction without approval, which can lead to penalties and forced demolition
Final Tips for a Smooth Council Approval Process
- Start with research: Know your zoning, council rules, and what category your project falls under.
- Talk to council early: Most councils offer planning advice sessions.
- Hire experienced professionals: This can be the difference between approval and rejection.
- Prepare detailed, accurate documentation: Incomplete applications cause major delays.
- Communicate with neighbours: Especially for larger projects—early discussions can ease objections.
- Don’t start building until you have formal approval: It’s illegal and can result in serious consequences.
