Noise Complaints Strata NSW: What Buyers Should Look for Before They Buy

Noise is a leading reason households are dissatisfied with their accommodation — and it is also one of the most discoverable issues before exchange. According to the Australian Bureau of Statistics, among dissatisfied households in 2019–20, 31.8 per cent cited “noise level” as a reason for their dissatisfaction (ABS Housing Mobility and Conditions). The good news is that strata records often contain clear warning signs of acoustic trouble, from repeated complaints in meeting minutes to formal notices and tribunal applications.

Before you buy, understanding how noise is regulated — and how disputes are escalated — helps you decide whether a scheme is well managed or carrying unresolved tension. This article explains what to look for in strata documents, what the law says about nuisance and by-laws, and when noise patterns should give you pause.

How does the law handle noise in NSW strata?

Noise in strata schemes is governed by two overlapping frameworks: the Strata Schemes Management Act 2015 (NSW) and the scheme’s own by-laws.

Section 153 of the Strata Schemes Management Act 2015 (NSW) prohibits the use of a lot in a way that causes a nuisance, hazard, or unreasonable interference with another lot or the common property (Grace Lawyers). This is a broad provision that applies regardless of what the by-laws say, and it is frequently relied upon in NCAT disputes.

In addition, every strata scheme has by-laws that regulate day-to-day behaviour. Under NSW rules, an owners corporation may adopt the model by-laws provided in regulation, create their own, or use a mixture of both (NSW Government — By-laws). Common by-law topics include pets, smoking, short-term rental accommodation, parking, and noise. A well-drafted noise by-law will typically set quiet hours, restrict loud music or parties, and address mechanical noise such as power tools or alarms.

Buyers should check both the by-laws and local council rules, since some noise sources — like construction hours or barking dogs — may also fall under council regulation (NSW Government — Noise).

What noise warning signs appear in strata records?

The strata records held by the owners corporation can reveal whether noise is a persistent problem or an occasional annoyance. From 11 June 2024, records must be kept electronically, and communications sent or received by the owners corporation and strata committee must be retained for seven years (NSW Government — Record Keeping). Meeting minutes, notices, and voting papers are also kept for seven years, giving buyers a reasonably long history to review.

When reading a strata report, look for these patterns:

• Repeated noise complaints in meeting minutes. A single mention of a loud party is usually manageable. Multiple entries across several meetings suggest a recurring issue that the committee has not resolved.
• Notices to comply. Under section 146 of the Strata Schemes Management Act 2015 (NSW), an owners corporation may issue a notice to comply when a by-law is breached (NSW Government — Notice to Comply). A record of several notices sent to the same lot owner indicates escalating friction.
• Mediation records. Mediation is compulsory for most strata disputes before NCAT (NSW Government — Disputes). If mediation has been attempted more than once for noise, the dispute is likely entrenched.
• NCAT applications. Applications for orders or penalties signal that informal resolution has failed. These appear in strata records and are a strong indicator of ongoing conflict.

What questions should buyers ask about building design and noise?

Not all noise problems are behavioural. Some stem from the building itself. Before you commit, consider asking or inspecting for design-related acoustic risks.

Has hard flooring been installed without acoustic certification?

Under NSW strata renovation rules, hard flooring installations require an acoustic certificate demonstrating adequate sound insulation (NSW Government — Renovations). If multiple lots have replaced carpet with timber or tile without approval, sound transmission between floors may be elevated. This is particularly relevant in older schemes where original carpet has been removed over time. You can read more about the approval process in our guide to strata renovation approval NSW.

What do the by-laws actually say about noise?

Some schemes have detailed noise by-laws with defined quiet hours; others rely on generic model by-laws. Specific rules are usually easier to enforce and show the committee has invested time in governance.

Is the building age or construction relevant?

Older buildings may have thinner walls or less insulation than modern apartments. This does not mean every older building is noisy, but it is sensible context when combined with other clues in the records.

How is a noise complaint escalated in a strata scheme?

When noise becomes a formal dispute, NSW law provides a stepped enforcement pathway (NSW Government — By-laws):

Stage	Action	Outcome
1	Informal discussion	Owners or the committee speak with the resident directly.
2	Notice to comply	Issued under section 146 of the Strata Schemes Management Act 2015 (NSW). Should refer to one by-law only; the strata committee must convene a meeting unless a strata manager has been delegated this function. Can be sent by post or email. The secretary or manager should keep a copy and a record of service (NSW Government — Notice to Comply).
3	NCAT application	If the notice is ignored, the owners corporation may apply for orders. Mediation is compulsory for most strata disputes before NCAT, though some matters — such as penalties, inspection of records, or the compulsory appointment of a strata manager — bypass it (NSW Government — Disputes).
4	NCAT penalty order	NCAT may impose a fine of up to $1,100 for a first breach of a by-law.
5	Continued breach	For continued breaches, penalties rise to $2,200. If a previous NCAT order is ignored, the penalty can reach $5,500 (NSW Government — By-laws).

Common sources of strata noise complaints include barking dogs, power tools, loud music, alarms, construction, and noisy cars (NSW Government — Noise). Understanding this pathway helps buyers interpret what they see in the records. A scheme that has reached stage 4 or 5 repeatedly may have deeper governance or cultural issues than a scheme still resolving matters informally.

When is a noise issue a deal-breaker versus manageable?

A single noise complaint is rarely a reason to walk away. Most strata schemes deal with occasional disputes, and the ABS found that 82.9 per cent of all households were satisfied with their accommodation (ABS Housing Mobility and Conditions). The key is to look for patterns.

Manageable signals:

• One or two complaints over several years.
• Clear committee action: notices issued, mediation attempted, and the issue resolved.
• Updated by-laws that address noise specifically.
• Recent acoustic upgrades or approvals tracked in the records.

Concerning signals:

• The same lot owner or the same noise source appears repeatedly across meeting minutes.
• Multiple NCAT applications with escalating penalties.
• Committee minutes show avoidance or reluctance to enforce by-laws.
• A culture of informal retaliation rather than formal process.

Buyers should remember that noise disputes are not just about the offender — they also reflect how the owners corporation manages conflict. A committee that acts promptly and fairly is usually a better long-term prospect than one that lets grievances fester.

Frequently asked questions

Can an owners corporation fine someone for making noise?

An owners corporation cannot issue fines directly. It may issue a notice to comply under section 146 of the Strata Schemes Management Act 2015 (NSW), and if the breach continues, it can apply to NCAT for a civil penalty. NCAT may then order a fine of up to $1,100 for a first breach, rising to $2,200 for continued breaches, or up to $5,500 if a previous order is ignored (NSW Government — By-laws).

Do I have to go to mediation before taking a noise complaint to NCAT?

For most strata disputes, mediation is compulsory before applying to NCAT. However, some matters bypass this requirement, including applications for penalties, orders to inspect records, and applications for the compulsory appointment of a strata manager (NSW Government — Disputes).

How far back should I check strata records for noise complaints?

Meeting minutes, notices, voting papers, and all communications sent or received by the owners corporation and strata committee must be kept for seven years (NSW Government — Record Keeping). From 11 June 2024, these records must also be kept electronically. Reviewing at least three to five years of minutes will usually reveal whether noise is a recurring theme.

Is hard flooring always a noise risk in apartments?

Not necessarily. Under NSW strata renovation rules, hard flooring installations must be supported by an acoustic certificate showing adequate sound insulation (NSW Government — Renovations). If the proper approvals and certificates are on file, the installation is likely compliant. The risk arises when flooring has been replaced without approval or documentation.

Can local council rules override strata by-laws on noise?

Yes, in some situations. Buyers should check both the strata by-laws and local council rules, because noise sources such as construction hours, barking dogs, and vehicle alarms may be regulated by council as well as by the strata scheme (NSW Government — Noise).

Noise complaints are common, but the difference between a manageable neighbourly disagreement and a scheme-wide problem usually shows up in the strata records. Before you exchange, it pays to know what the minutes, by-laws, and renovation approvals actually say about acoustic risk and dispute history.
