A rear extension can look straightforward on a sketch, then become far more involved once setbacks, drainage, heritage controls and neighbouring properties are considered. Council approvals are where a renovation moves from an idea to a project that can be built legally, safely and with a clear plan. Getting this stage right early protects your budget, reduces avoidable delays and gives every trade a coordinated set of documents to work from.

For Sydney homeowners, the approval pathway depends on the property, scope and local planning controls. A new kitchen within an existing layout may require little more than compliant building work. A second-storey addition, substantial extension or heritage restoration usually needs considerably more planning. The right answer is never based on a neighbour’s project or a generic online checklist.

When do council approvals apply?

Approval requirements are determined by the work proposed, the site and the planning rules that apply to the address. In NSW, residential projects commonly follow either a Development Application, known as a DA, or a Complying Development Certificate, known as a CDC. Some lower-impact work may be exempt development, provided it meets strict standards. Building work can also require a construction certificate or equivalent certification before it starts.

A DA is generally required where a proposal falls outside the set standards for complying development, where the site has planning constraints, or where council needs to assess the design on its individual merits. It is common for larger extensions, new builds, work in heritage conservation areas and projects involving more complex site conditions. Council assesses matters such as privacy, overshadowing, streetscape, parking, stormwater and environmental impacts.

A CDC can be a faster pathway for eligible projects that meet all applicable development standards. However, faster does not mean easier or less detailed. The design still needs to comply with defined rules for height, setbacks, floor space, drainage, bushfire requirements and other controls. A small variation can make a CDC unsuitable and require a DA instead.

Exempt development is limited to specific low-impact work. Homeowners should be cautious about assuming an internal renovation is automatically exempt. Removing a wall, changing plumbing locations, altering structural elements or working in a heritage property can trigger separate requirements. Compliance with the National Construction Code and relevant Australian Standards remains necessary regardless of the planning pathway.

The site often decides the pathway

Two similar extensions can have completely different approval requirements. A level block with a standard zoning may suit a CDC, while the same extension on a sloping site, flood-prone land or a heritage-listed property may need a DA and specialist reports. Sewer locations, easements, significant trees and bushfire-prone land can also affect the design and construction method.

This is why early due diligence matters. It is more cost-effective to identify constraints before a design is developed than to redraw plans after an application is lodged. A well-managed pre-construction process checks the site, planning controls and likely approval route before key decisions are locked in.

What a complete approval package needs

Councils and certifiers assess documentation, not intentions. Plans need to demonstrate exactly what will be built and how the proposal responds to the property. Incomplete or inconsistent information is one of the most common reasons an application stalls.

The required documents vary by project, but a typical approval package may include architectural plans, a site survey, a statement of environmental effects, BASIX documentation, stormwater design and structural engineering details. Depending on the site, it may also need a heritage impact statement, arborist report, geotechnical assessment, bushfire assessment, acoustic report or landscape plan.

The documents need to align. For example, the roof form shown on elevations must match the drainage approach, structural design and BASIX commitments. If an extension changes after approval, the team must check whether the change can be managed through certification or needs a formal modification. Treating approvals as paperwork separate from the build creates risk later, particularly when materials, windows or layouts are selected.

For homeowners, the practical benefit of a coordinated package is certainty. It allows accurate quoting, supports realistic construction planning and helps avoid the costly situation where work is priced before the specifications are understood.

The council approval process, step by step

The strongest approval strategy starts well before lodgement. It begins with a clear brief: how the family uses the home, what spaces are needed, the desired budget and the non-negotiables. From there, the design can be tested against the site and planning framework rather than being treated as a purely aesthetic exercise.

1. Review the site and project scope

A site inspection and planning review identify obvious constraints, access considerations and the likely level of documentation required. This is also the right time to consider the existing home. Older Sydney properties can contain undocumented alterations, ageing services or structural conditions that need to be addressed in the renovation design.

2. Develop a compliant design

Concept plans should balance the homeowner’s goals with setbacks, building height, private open space, solar access and neighbour impacts. A good design does not simply aim for the largest possible addition. It creates useful, well-connected space while reducing the likelihood of planning objections or assessment issues.

3. Engage the required consultants

Surveyors, engineers, certifiers and specialist consultants provide the information needed to support the selected pathway. Their input should be coordinated early. Leaving stormwater, structure or energy-efficiency requirements until late in the design stage can force changes to floor levels, window sizes, roof design and cost.

4. Lodge, respond and obtain consent

For a DA, the application is lodged through the NSW planning system and assessed by the relevant consent authority. Council may request additional information or amendments. Timeframes vary significantly according to the council, project complexity, workload and whether neighbour submissions or specialist referrals are involved.

For a CDC, an accredited certifier or council assesses whether the proposal meets the required standards. The process can be more direct, but only where the proposal is genuinely compliant. Trying to force a non-compliant design into a CDC pathway can cost more time than choosing a DA from the outset.

5. Prepare for construction

Approval is a major milestone, not the start signal on its own. Before building begins, the project needs the appropriate construction certification, insurance, contracts, detailed selections and site planning. Required inspections must be scheduled through construction, and final certification is needed at completion. These steps protect the homeowner’s ability to sell, insure and enjoy the improved home with confidence.

Common causes of approval delays

Most delays are preventable, although not every factor is within a homeowner’s control. Assessment queues, public holidays and authority referrals can affect timing. What can be controlled is the quality of the application and the speed of responses when questions arise.

Unclear scope is a frequent problem. When owners continue making major layout changes while documents are being prepared, every consultant may need to revise their work. Incomplete surveys, missing reports and plans that do not reflect current selections can have the same effect.

Neighbour concerns are another consideration. A proposal that appears reasonable from inside the home may affect a neighbour’s sunlight, privacy or outlook. Early design decisions such as window placement, screening, boundary setbacks and roof height can reduce these impacts. Communication can help, but it does not replace a design that responds properly to planning controls.

Budget pressure can also lead to poor decisions. Removing necessary consultant work to reduce upfront costs may result in a weaker application or construction variations later. The better approach is to establish a realistic approval and pre-construction allowance at the beginning, then make informed choices about scope and finishes.

Why one managed team makes a difference

Homeowners do not need to become approval specialists, but they do need visibility over the process. A managed project should provide a clear sequence of design, documentation, lodgement, approvals, certification and construction planning, with honest advice when a decision affects timing or cost.

At H.E.A.R, council approval management is integrated with the wider renovation process. That means the approval strategy is considered alongside buildability, trades, material selections and the construction programme. It reduces handover gaps between designers, consultants and builders, while keeping the homeowner informed about what is happening and what is required next.

The best time to address council requirements is before construction is priced and scheduled. With the right planning, a renovation can move forward on approved, coordinated documentation rather than assumptions – giving your family a clearer path from first ideas to a finished home.
