Granny flats: What's changed
Have your say on the proposed Development Contributions Policy for Granny Flats.
What is this about?
Council charges financial contributions for land use and building development. This money helps pay for infrastructure needed as our district grows, such as roads, water services and reserves.
Changes to legislation mean we can no longer charge these contributions for granny flats (small stand-alone dwellings) that do not need resource consent without amending the District Plan.
Introducing a development contributions policy for granny flats would allow us to keep recovering growth-related costs from granny flats that now don’t require a resource consent and may or may not require a building consent.
Why can’t we continue with our current approach?
In January 2026, changes to legislation removed Council’s ability to collect financial contributions for some granny flats through the resource consent process.
Development contributions are now the only way we can do this without amending the District Plan. Amending the District Plan is not a practicable option given the government’s “plan stop” which restricts Council’s ability to undertake plan changes pending implementation of the new Planning Act.
Council does not currently use development contributions, so we can’t recover growth-related costs from granny flats that no longer need resource consent. The proposed policy would allow us to keep recovering against these costs. It is made under the Local Government Act 2002, and the charge would be issued at the Project Information Memorandum or building consent stage rather than as a condition of a resource consent.
Without this policy, we risk a growth funding gap. Granny flats add to demand for infrastructure as the district grows. We do not think it is fair for other parts of the community to cover these costs.
Why does this matter?
New homes can increase demand on local infrastructure, including roads, water supply and wastewater networks. Both financial contributions and development contributions help fund the infrastructure needed to support growth.
Without a way to recover these growth-related costs from development, there is a risk that a funding shortfall could occur. This could mean existing ratepayers ultimately carry more of the cost of providing infrastructure needed to support development.
The purpose is not to create a new cost for homeowners. It is to provide a new mechanism for Council to continue recovering growth-related costs that have previously been recovered through financial contributions.
What stays the same?
- Recovery of growth-related costs from granny flats.
- Granny flats that require resource consent will continue to be assessed under the operative District Plan and financial contributions approach.
- Council will continue to use the Household Equivalent (HHE) to assess the development contribution for a granny flat. This is a standard measure councils use to estimate how much demand a new development places on public infrastructure.
- Each granny flat will be assessed as 0.5 HHE per flat. This matches the financial contributions for similar minor residential dwellings that require a resource consent.
- Financial contribution models that determine the cost of growth-related infrastructure attributable to a HHE will continue to be used as the basis for the development contribution charges.
What will change?
- Granny flats that don’t require a resource consent will be considered under the proposed policy.
- When Council issues a Project Information Memorandum or building consent for a granny flat, it may also issue a notice telling the owner how much development contribution is payable.
- Council cannot charge ecological development contributions under the proposed policy. However, it will continue to charge ecological financial contributions for granny flats that need resource consent.
- There is no ability to apply for a remission to the development contribution. Note under financial contributions, waivers can only be provided for on a category basis through a plan change or annual plan process rather than for individuals by specific application.
