Noise Complaints in Apartments: What Strata Can and Can't Enforce
If there's one issue that defines the tension of apartment living, it's noise. Footsteps on floorboards above. Music at midnight. Dogs barking while their owners are at work. Construction that starts at 7am on a Saturday. According to NSW Fair Trading data, noise-related disputes consistently rank as the single most common category of strata complaints.
But here's what many apartment residents don't realise: the rules around noise in strata are far more nuanced than "keep it down after 10pm." Understanding what your strata scheme can actually enforce — and what falls outside its jurisdiction — is essential to managing noise disputes effectively.
What Strata By-Laws Can Regulate
Strata by-laws set the internal rules for living in a scheme. Most strata schemes have by-laws that address noise, but the scope and specificity vary enormously. The model by-laws in NSW (Schedule 3 of the Strata Schemes Management Regulation 2016) include a general provision requiring owners and occupiers not to create noise likely to interfere with the peaceful enjoyment of another owner or occupier.
Common by-law provisions include restricting hard flooring installations (requiring acoustic underlay), setting quiet hours (typically 10pm–8am on weekdays, 10pm–9am on weekends), requiring musical instruments and amplified sound to be played at reasonable volumes, limiting construction and renovation noise to specified hours, and requiring pets to be managed to minimise barking and other disturbance.
| Noise Source | Strata By-Law Enforceable? | Council/EPA Enforceable? | Best Resolution Path |
|---|---|---|---|
| Loud music after quiet hours | Yes — breach of by-law | Yes — residential noise provisions | Strata notice to comply, then mediation |
| Footstep noise from upstairs | Depends — only if flooring by-law exists | Rarely — considered "normal domestic noise" | Mediation; acoustic assessment if flooring non-compliant |
| Barking dog during the day | Possible — if pet management by-law exists | Yes — council nuisance animal provisions | Council complaint often more effective than strata |
| Building renovation noise | Yes — within permitted hours | Yes — EPA Noise Guide provisions | By-law enforcement for hours; council for excessive noise |
| Common area noise (pool, gym) | Yes — by-law can set operating hours | Possibly — depends on noise level | Committee decision on hours and rules |
| Airbnb guest parties | Yes — breach of by-law and STRA code | Yes — residential noise provisions | By-law enforcement + STRA code complaint |
What Strata Cannot Enforce
There are important limits to what strata can regulate:
Normal domestic noise. The sound of footsteps, closing doors, running water, cooking, conversation at normal volume, and children playing are generally considered normal domestic noise. While these sounds can be annoying — particularly in buildings with poor acoustic insulation — they typically cannot form the basis of a successful by-law complaint unless the noise is at objectively unreasonable levels.
Noise from outside the scheme. Traffic, neighbouring construction, flight paths, and other external noise sources are beyond the control of the owners corporation. These are council or EPA matters.
Noise within lot boundaries. If noise stays within the lot and doesn't transmit to neighbours, strata by-laws generally don't apply. The issue arises when noise crosses lot boundaries and affects other occupants.
The Enforcement Process
When noise does breach a by-law, here's how enforcement works:
Step 1: Direct conversation. Always start here. Most noise issues stem from a lack of awareness rather than malice. A polite conversation or note can resolve the majority of problems.
Step 2: Written complaint to the strata manager. If direct communication doesn't work, lodge a formal complaint. Include dates, times, duration, and the nature of the noise. Multiple complaints from different residents strengthen the case.
Step 3: Notice to comply. The owners corporation can issue a formal Notice to Comply under section 146 of the Strata Schemes Management Act 2015 (NSW). This puts the offending owner or occupier on notice that they are breaching a by-law and must stop the behaviour.
Step 4: Financial penalty. If the behaviour continues after a notice to comply, the owners corporation can apply to NCAT for an order imposing a penalty of up to ,100 per breach (or ,200 for a repeat offence).
Step 5: Mediation and NCAT. If enforcement through the owners corporation is unsuccessful, individual owners can pursue mediation through Fair Trading and, if necessary, apply to NCAT for orders.
The Acoustic Standards Gap
One of the most frustrating aspects of noise in apartments is that many buildings — particularly those built before 2004 — were constructed to acoustic standards that would be considered inadequate today. The National Construction Code (NCC) acoustic requirements were significantly strengthened in BCA 2004 and have been incrementally improved since.
| Building Age | Typical Acoustic Standard | Noise Transfer Experience |
|---|---|---|
| Pre-2004 | Minimal acoustic requirements in BCA | Significant airborne and impact noise transfer between lots |
| 2004–2015 | Improved BCA requirements (Rw 50, Ln,w 62 for floors) | Moderate noise transfer; footstep noise still common |
| Post-2015 | Further strengthened NCC requirements | Generally good; well-built buildings have minimal noise transfer |
If your building has poor acoustic performance due to its age or construction quality, the realistic options are limited. Retrofitting acoustic insulation into an existing building is expensive and disruptive. The most practical approaches are by-laws requiring acoustic underlay for hard flooring, rugs in high-traffic areas, and reasonable expectations calibrated to the building's construction era.
Renovations: The Flooring Flashpoint
The single most contentious noise issue in strata is flooring renovations — specifically, replacing carpet with hard flooring (timber, tiles, laminate). Hard flooring dramatically increases impact noise transmission to the lot below.
Many strata schemes now have by-laws requiring acoustic underlay or acoustic testing before hard flooring installation. If your building doesn't have such a by-law, it's worth proposing one at the next AGM. A well-drafted flooring by-law typically requires a minimum Impact Isolation Class (IIC) rating for any hard flooring installation, proof of acoustic compliance before approval is granted, and installation by a qualified contractor following manufacturer specifications.
How UnitBuddy Helps
UnitBuddy's building wellness assessment includes resident satisfaction indicators that capture noise-related issues. Buildings with robust noise management by-laws and good acoustic construction score higher — reflecting the reality that noise management directly affects liveability and property value.
Noise in apartments isn't going away — it's inherent to shared living. But the difference between a well-managed building and a noisy one isn't the thickness of the walls. It's the quality of the by-laws, the willingness of the committee to enforce them, and the culture of neighbourly communication.
