The North Shore 24-Bedroom Complex

Auckland Council compliance officers recently inspected a major operation on the North Shore consisting of four homes, each containing six bedrooms with private bathrooms. The complex functioned as a 24-bedroom boarding house, with numbered rooms and shared communal spaces. However, the properties were originally consented only as five-bedroom family homes. Neighbors raised alarms regarding the lack of professional fire safety measures, such as sprinklers and emergency evacuation procedures, noting that only basic domestic smoke detectors were installed despite the high density of unrelated residents.

Exploiting the Single-Tenancy Loophole

When faced with council enforcement, the majority of illegal lodge owners including the North Shore landlord opted to switch to a single tenancy agreement rather than applying for the necessary resource consents. Under New Zealand’s Building Act, specific fire safety systems are required once a boarding house exceeds five residents. By using a "head tenant" model or reducing the official number of boarders to five per household, landlords can legally reclassify the property as a standard family rental, effectively bypassing the rigorous safety standards required for commercial boarding houses.

Safety Implications and Emergency Risks

Auckland Council’s compliance manager, Adrian Wilson, emphasized that the distinction between a boarding house and a family flat is rooted in safety. In a standard tenancy, residents are expected to have a social link, such as being family or friends, which increases the likelihood that they will alert one another during an emergency. In a boarding house situation, occupants are often unrelated and transient, creating a "disjointed" environment where individual fire separation between rooms and advanced alarm systems are critical. The current loophole allows landlords to house the same number of people without providing these life-saving protections.
