New Methamphetamine Regulation

New regulations for managing methamphetamine contamination in rental properties came into effect on 16 April 2026. These changes were designed to provide clear, consistent rules for landlords, tenants, and property managers when dealing with contamination.

The regulations introduce clear thresholds and responsibilities:

• A property is considered contaminated if meth residue exceeds 15µg/100cm²
• Affected areas must be decontaminated to at or below this level
• If contamination exceeds 30µg/100cm², the property may be considered uninhabitable
• In high-level contamination cases, both landlords and tenants can end the tenancy.

These changes place greater importance on clear evidence and documented property condition.

Baseline Testing: Why It Matters

Baseline testing is a professional methamphetamine contamination assessment conducted prior to the commencement of a tenancy. It establishes a clear and documented record of the property’s condition at the outset, providing an objective point of reference from day one.

This becomes particularly important should contamination be identified at a later stage. A baseline report enables a more accurate determination of when the contamination occurred, whether during the tenancy or prior. This can assist in minimising disputes and reducing exposure to unnecessary decontamination costs or liability.

In addition, baseline testing demonstrates a proactive approach to compliance with current regulations and industry standards. It reflects prudent risk management and supports a safe, transparent, and equitable process for all parties involved.

Please note that baseline testing is undertaken at your discretion, and we will not arrange this service without your prior authority. Should you wish to include baseline testing as a standard requirement between future tenancies, we invite you to contact your property manager to have this formally recorded on your property file.
