Granny Flats: A Step Toward Solving NZ’s Housing Crisis

The New Zealand Government has unveiled a bold initiative to help tackle the nation’s housing crisis. By proposing changes that would allow homeowners to build granny flats of up to 60 square metres without requiring building or resource consents, the policy aims to streamline construction and boost affordable housing options. While the proposal holds promise, it’s not without its challenges.


The Details of the Proposal

Under the proposed changes, small, self-contained homes—commonly referred to as granny flats—could be built on properties with existing houses. These secondary dwellings would be exempt from the usual building and resource consents, provided they adhere to specific safety and quality criteria outlined in the Building Code.

This policy is part of the government’s broader effort to address housing shortages while reducing the regulatory burden on homeowners. By cutting red tape, officials hope to see a surge in secondary dwellings, creating more affordable housing and offering homeowners greater flexibility with their properties.


What’s in it for Homeowners?

The benefits of this proposal are clear:

  • Boosting Housing Supply: Easier regulations could encourage more property owners to build granny flats, increasing the number of homes available across the country.

  • Lower Costs: With no need for building or resource consents, homeowners can save thousands in compliance costs, making construction more accessible.

  • Multi-Purpose Use: Granny flats can serve as rental properties, housing for extended family, or even office spaces, giving homeowners new ways to utilize their land.


As the housing crisis continues to impact many New Zealanders, this proposal could be a game-changer, offering practical solutions to long-standing problems.


The Fine Print: Potential Challenges

While the proposal’s goals are commendable, questions remain about its implementation. Critics and industry experts have raised concerns about several aspects:

  • Ensuring Quality: Without the traditional oversight of consents, the burden of ensuring compliance with the Building Code falls heavily on builders and supervisors. The proposal mitigates this by requiring work to be completed by licensed professionals, but some fear standards could slip without rigorous checks.

  • Infrastructure Pressure: Adding granny flats to existing properties may strain infrastructure like water supply, sewage systems, and road access. Councils could face increased demands to upgrade facilities, raising concerns about how these upgrades will be funded.

  • Environmental Risks: Building without resource consents could lead to unintentional environmental harm, particularly in areas prone to flooding or erosion. Policymakers have acknowledged this risk and propose measures to ensure environmentally sensitive zones are protected.


Balancing Opportunity with Responsibility

Architects and builders alike are optimistic about the opportunities this proposal offers but emphasize the importance of thoughtful implementation. While it simplifies the process for homeowners, maintaining safety, durability, and sustainability must remain priorities.

The government’s move signals a willingness to innovate and adapt to the pressing challenges of the housing market. However, success will depend on balancing streamlined processes with safeguards to protect communities and the environment.


A Path Forward

If implemented effectively, the 60m² secondary dwelling proposal could revolutionize how New Zealand approaches housing. By making granny flats more accessible, it has the potential to empower homeowners, increase housing supply, and make a significant dent in affordability issues. However, as with any policy shift, the devil lies in the details. Ensuring the long-term success of this initiative will require collaboration between government bodies, councils, and industry experts.


For now, the proposal represents a hopeful step toward creating a more accessible and adaptable housing market for all New Zealanders.
