Starting from 1 July 2017, it is mandatory for an owner, landlord or agent of commercial buildings or tenancies to produce and register a Building Energy Efficiency Certificate with the Building Energy Efficiency Register before they offer to sell, lease or sublease a commercial building that exceeds 1000 square metres.
A fine of up to $210,000.00 followed by $21,000.00 for each subsequent day of non-compliance may be imposed if this mandatory disclosure is not adhered to.
