Whether it’s repairing an ageing building, complying with fire safety orders, or adding new levels to remain competitive in the market, strata communities inevitably face building and development decisions. Even smaller projects—like a lot owner wanting to do structural renovations—can trigger the need for approvals.

Understanding the approval process is essential for avoiding disputes, protecting safety, and keeping your building compliant with NSW law.

When Is Development Approval Needed?

While each state and territory has its own rules, the process in NSW is broadly consistent. Generally, you need development approval from your local council if you want to:

• Erect, structurally alter, or demolish any building (including outhouses and sheds)
• Excavate significant land areas
• Paint or alter heritage-listed properties
• Subdivide excess land

Even if council approval isn’t required—for example, for cosmetic renovations—your project may still need owners corporation approval under your building’s by-laws.

What Councils Consider

Environmental planning instruments set out guidelines for development in each local area. High-impact applications are often advertised so neighbours can lodge objections. Common concerns include:

• Overshadowing and loss of natural light
• Impact on privacy or views
• Noise during and after construction
• Parking congestion
• Streetscape changes or character impacts

If you’re adding extra floors, councils will assess the building’s setback to ensure it doesn’t dominate the streetscape.

How Long and How Much?

Major development approvals can take 9–18 months and cost up to $200,000 once expert reports, drawings, and objections are factored in. The timeline varies depending on the complexity of the proposal and the number of objections lodged.

In the meantime, if work is being undertaken to comply with urgent fire or life safety orders, temporary measures may be required to keep residents and visitors safe while approvals are processed.

The Role of the Owners Corporation

The owners corporation must consent to any development approval application affecting the strata scheme. Importantly, giving consent to lodge an application does not stop owners from objecting to the proposal later—a nuance that often creates heated discussions in strata meetings.

This is why it’s critical for strata committees to:

• Understand the approval process
• Communicate clearly with lot owners
• Manage expectations early to reduce conflict

Why Good Consultants Matter

From our experience at Metro Strata, the building and development process can be one of the most complex issues for strata communities. Navigating planning laws, council requirements, and by-law obligations requires expertise.

Specialist consultants attuned to strata needs can help whether you’re:

• The applicant seeking approval, or
• An owner lodging an objection

They ensure the process is followed correctly, reduce delays, and protect the community’s long-term interests.

Final Word

Building and development approvals can be slow, costly, and complicated. But with the right advice, your strata community can meet safety standards, stay compliant, and even add long-term value to the property.
