Is It Safe to Live Near a Landfill? A Victorian Guide

For homeowners, residents and buyers near a current or former landfill in Victoria who want a straight answer about safety. Last reviewed June 2026.

Is it safe to live near a landfill?

For most people, living near a landfill is safe. The honest answer is that it depends on your specific property and the landfill, but the issue is usually manageable and well understood. The real concern is not the air outdoors — it is landfill gas moving through the ground and collecting inside an enclosed or below-ground space, such as a basement or a void under a slab. Modern homes and new developments near landfills are assessed for this and, where needed, protected. Below we explain what landfill gas is, when it genuinely matters, how Victoria manages it, and how to find out about your own home.

What is landfill gas, and why do people worry about it?

When organic waste breaks down in a landfill without much oxygen, it produces landfill gas. This gas is approximately 50% methane and approximately 50% carbon dioxide, with small amounts of trace gases such as hydrogen sulphide and volatile organic compounds. Two of those properties are why landfill gas gets attention.

• Methane is flammable. In air, methane can ignite when it sits between about 5% and 15% by volume. That only becomes a hazard if gas builds up in a confined space — a cellar, a lift shaft, a sealed void under a floor — and meets an ignition source.
• Methane and carbon dioxide can displace oxygen. In a poorly ventilated, enclosed space, a build-up can lower the oxygen level. Again, this is a confined-space concern, not an open-air one.

Outdoors, landfill gas disperses into the atmosphere quickly and is not a meaningful risk to people going about their day. The thing that turns it from a non-issue into something worth assessing is gas finding its way into an enclosed or below-ground part of a building. That distinction — open air versus enclosed space — is the single most important thing to understand, and it is reassuring rather than alarming.

When is it actually a concern — and when is it not?

Whether gas can reach a home depends on three things working together, which specialists describe as the Source–Pathway–Receptor model: a source of gas, a pathway for it to travel along, and a receptor (a person or building) at the end.

• The source. Landfill gas generation is highest when a tip is young and falls steadily over the decades after it closes. A roughly 30-year aftercare period is a common benchmark, and by 50 years or more generation is usually low. Age alone is not the whole story — many old tips are poorly recorded — but an old, long-closed landfill generally produces far less gas than a recent one.
• The pathway. Gas moves through permeable ground such as sand, gravel and loose fill, through fractured rock, and very often along service trenches and underground conduits, which act as ready-made channels. Dense clay and basalt, by contrast, resist sideways movement. This is why geology matters so much, and why two homes the same distance from a tip can face very different situations.
• The receptor. Risk is highest for buildings with basements, lift shafts or enclosed underfloor voids, and for new housing where people will live for years. A surface-level, well-ventilated home is a lower concern, and open space such as a garden lower still.

If any one of those links is missing — little gas being produced, no pathway for it to travel, or no enclosed space for it to collect in — the risk is low. For a great many properties near former tips, that is exactly the case.

How Victoria manages this

You are not relying on luck here. Victoria has a clear, risk-based system for managing development on and near landfills, overseen by councils (as the planning authority) and EPA Victoria. When someone proposes new development near a current or former landfill — particularly homes or other sensitive uses — the council can require the risk to be assessed before granting a planning permit.

The current guidance is EPA Victoria's landfill buffer guideline (2024), published in August 2024, which superseded the older guidance many people may still find online. The approach is staged: depending on the landfill's characteristics and the type of development proposed, the outcome is one of three — no further assessment, a landfill gas risk assessment, or an environmental audit (now a Part 8.3 environmental audit under the Environment Protection Act 2017). In practice this means low-risk situations are filtered out early, and effort is concentrated where it is actually needed.

One point that causes a lot of confusion is worth clearing up. You may read that landfills need a buffer of up to 1,500 metres to homes. That figure is about where a brand-new landfill can be sited — it is not the distance that decides whether your existing home is at risk. For development near an existing or closed tip, landfill gas has historically been considered within about 500 metres, but there is no single magic number: your council and the EPA guideline applied to your specific site determine what, if anything, is needed.

What about my health?

It is natural to worry about health, and you deserve a measured answer rather than a scary one. Provided landfill gas is not accumulating inside an enclosed space, day-to-day life near a former landfill does not expose you to the gas in any meaningful way, because it disperses outdoors. The trace gases can produce odours at times, which are unpleasant but are a nuisance issue rather than the core safety concern. The genuine hazards — fire or explosion risk, and oxygen displacement — are confined-space problems, which is precisely why the whole system is built around keeping gas out of buildings. Where a site does warrant attention, the response is engineering and protection, not leaving people exposed.

Does living near a landfill affect property value?

This is a fair and common question. The presence of a former landfill nearby can affect buyer perception, and a property within a council's area of interest may have planning conditions attached to future building work. But a clear, well-documented assessment showing low risk — or a home built with appropriate gas protection — removes much of the uncertainty that worries buyers. Knowing the facts about your property, rather than guessing, is usually what protects value best.

How to find out about your own property

If you would like to know where you stand, here is a sensible order to go about it.

1. Search Victoria Unearthed. Victoria Unearthed is a free public online map run by the Victorian Government that brings together the landfill register, potentially contaminated land and environmental audit locations. It is the right first place to look up an address.
2. Treat a clear result with healthy caution. Many old or closed tips are poorly documented or were never registered, so a clean map result is reassuring but not a guarantee. A professional desktop review also checks historical aerial photographs and other records that the map does not capture.
3. Get a professional check if anything is uncertain — especially if you are buying, planning to build, or your home has a basement or other below-ground space.

A landfill gas risk assessment by an environmental consultant starts with that desktop study and the Source–Pathway–Receptor picture, and only goes further — a site walkover, or months of ground gas monitoring across different weather conditions — if the situation warrants it. For many homes, the desktop stage is enough to give a clear, calm answer.

If you would like to know whether your property is affected, the simplest first step is a professional check — you can request a free quote and Automated Environmental, a Victorian specialist in landfill gas risk assessments, will tell you what (if anything) your site needs. There is no pressure, and often the answer is reassuring.

Frequently asked questions

Is it safe to live near a landfill?

For most people, yes. The key risk is landfill gas collecting in an enclosed or below-ground space, not the open air, where gas disperses. Whether a particular home is affected depends on how much gas the landfill produces, whether there is a pathway through the ground, and whether the building has spaces where gas could gather. Many properties near former tips are low risk, and where a real concern exists it can be assessed and managed.

Can methane from a landfill get into my house?

It can, in some circumstances, which is why it is assessed. Methane can travel through permeable ground and along underground service trenches, and can enter a building if there is a pathway and an enclosed space such as a basement or a void under the floor. It is most likely to be a concern for buildings with below-ground spaces close to a landfill. Surface-level, well-ventilated homes are a much lower concern, and a risk assessment establishes whether your property has the conditions for it to happen.

What are the health effects of landfill gas?

The main hazards are confined-space hazards rather than open-air ones. Methane is flammable when it accumulates in a confined space, and both methane and carbon dioxide can displace oxygen in a poorly ventilated enclosed area. Outdoors the gas disperses and is not a meaningful exposure, though trace gases can cause occasional odours. Because the real risks involve gas building up inside a structure, the entire management system is designed to keep gas out of buildings.

Does living near a landfill affect property value?

It can affect buyer perception, and future building work may carry planning conditions. However, a clear assessment showing low risk, or a home built with appropriate gas protection, removes much of the uncertainty buyers worry about. Having documented facts about your property usually does more to protect its value than leaving the question unanswered.

How do I find out if my home is near a former landfill?

Start with Victoria Unearthed, the Victorian Government's free online map, which lets you look up an address against the landfill register and contaminated land records. Bear in mind that many old tips are poorly documented or unregistered, so a clear result is reassuring but not a guarantee. If you are buying, building, or have a below-ground space, a professional desktop review that also checks historical aerial photographs and records is the reliable next step.
