NSW residential tenancy regulations increasingly address landlord obligations regarding property conditions that affect tenant health and safety, with mould and dampness representing an area of growing regulatory attention given the genuine health implications these issues can carry for occupants. Landlords throughout Wollongong generally hold responsibility for addressing structural issues contributing to mould, such as inadequate ventilation systems, roof or plumbing leaks, or building defects, while tenants typically retain responsibility for reasonable everyday practices like running exhaust fans and avoiding excessive indoor humidity through practices like drying large amounts of laundry without adequate ventilation. Understanding this general division of responsibility helps both landlords and tenants navigate mould issues more constructively, recognising that resolving these problems effectively typically requires cooperation rather than adversarial positioning between the two parties. Property managers throughout the region increasingly recognise the value of proactive mould prevention and prompt professional response when issues arise, partly reflecting this evolving regulatory landscape around tenant health and habitability standards. Landlords and property managers uncertain about their specific obligations regarding a particular mould situation benefit from both professional mould assessment and, where appropriate, guidance from relevant tenancy authorities regarding their specific rights and responsibilities under current regulations.
