Granny flats in Rangiora & North Canterbury.
Seventy supplies house plans for properties in Rangiora & North Canterbury. Rangiora and North Canterbury include town sections, new subdivisions and lifestyle properties. Check river flood information, services and the usable building area. Private covenants can affect newer subdivisions, while rural sites may need longer connections or an on-site wastewater system. You arrange construction separately with a licensed builder.
Building consent and resource consent requirements
The building consent exemption and the national planning standard are separate. A project can proceed without either consent only when all the relevant requirements are met.
Schedule 1A, under the Building Act 2004
Building consent, if all Schedule 1A conditions are met
A new, detached, single-storey home up to 70 m² may be built without a building consent if every exemption condition is met. Licensed professionals, Building Code compliance, a Project Information Memorandum and council notifications are still required.
NES-DMRU, under the Resource Management Act 1991
Resource consent, if all relevant requirements are met
The national planning standard can permit one detached minor dwelling without resource consent when its standards and other relevant requirements are met. Some district and regional rules remain, including those for hazards, infrastructure and earthworks.
Both took effect on 15 January 2026. They do not retrospectively approve existing dwellings.
National planning standards
The NES-DMRU is the national planning standard for detached minor dwellings. These measurements apply when its requirements are met. A district plan can allow more generous measurements. Other relevant site restrictions still apply.
| Standard | Residential zone | Rural zone |
|---|---|---|
| Maximum internal floor areaMeasured to the internal face of the external walls. An attached or internally accessed garage counts inside it. | 70 m² | 70 m² |
| Maximum area of the site covered by buildingsThe 50% standard overrides any district plan coverage standard below 50% in a residential zone. | 50% | As required by the zone |
| Minimum distance from the main homeDistances are measured from the outside face of the wall cladding. | 2 m | 2 m |
| Minimum distance from the front boundary | 2 m | 10 m |
| Minimum distance from side and rear boundaries | 2 m | 5 m |
The permitted activity rule: One detached minor residential unit per site. It applies in residential, rural, mixed use and Māori purpose zones, as defined in the National Planning Standards, or the equivalent zones where a council has not implemented them yet.

Other requirements to check
In Rangiora & North Canterbury, check the following local consideration: Check Waimakariri District Council flood and planning information, title covenants and regional servicing requirements.
Flooding, coastal hazards, fault lines and land stability can affect the building location, floor level and need for consent. Check the council information and obtain site advice where needed.
Check connection requirements and capacity. Relevant regional plan rules still apply, including requirements for an on-site wastewater system.
Buildings near electricity lines and other significant infrastructure must meet the relevant safe-distance and planning requirements.
Rules can apply near airports, ports, industry and farming operations, or on contaminated land. They may affect where a home can be built and what design measures are needed.
Earthworks may need resource consent even when the dwelling does not. Subdivision requirements are separate and remain in place.
Relevant protections for heritage, cultural sites and outstanding natural features still apply.
Check covenants and easements on your property title. The national planning standard does not override private covenants, and more stringent council bylaws can still apply.
Development and financial contributions may be payable. Ask your council to confirm which charges apply to your project.
A district plan may allow a larger home or a smaller boundary setback. That does not change the separate Schedule 1A requirements. For example, an 80 m² dwelling or a 1 m setback would not meet the 70 m² and 2 m conditions for this building consent exemption.
Check the main eligibility conditions
Check these conditions with your designer and council. They are a starting point; all relevant exemption requirements must be met.
The minor dwelling must be physically separate from the principal home. An attached extension is assessed under different requirements.
The NES-DMRU planning standard requires a minor dwelling to be secondary to a principal home on the same site and in the same ownership. If both are proposed together, confirm the construction order and requirements with the council.
The NES-DMRU allows one detached minor dwelling per site. For a cross-lease, the site includes all the land under the cross-lease. A district plan may allow more, subject to its requirements.
The building consent exemption applies to new dwellings. A building conversion may meet the planning standard, but it is not covered by this building consent exemption.
Ground and climate considerations
Confirm ground bearing, drainage and flood information. Flat gravel land still requires an address-specific foundation assessment. Assess exposure to plains winds and any local snow requirements for the property. Check Waimakariri District Council flood and planning information, title covenants and regional servicing requirements. These requirements inform the adapted plans and the construction quote from your chosen builder.

Steps to plan your project

Review council maps and relevant district and regional rules for natural hazards, infrastructure and other restrictions.
Identify the water, wastewater and stormwater connections and confirm capacity. Check any requirements for an on-site wastewater system.
Apply for and receive a Project Information Memorandum before construction starts. It records the council information relevant to the property and proposed work.
Your designer confirms the design requirements for the property and prepares the required plans and documentation. The Schedule 1A exemption requires appropriately licensed professionals.
Notify the council before construction and provide the required completion documents afterwards. Your designer and builder must supply the records and certificates required for their work.
Frequently asked questions
What rent could a two-bedroom home earn in Rangiora & North Canterbury?+
The $580 weekly figure on this page is an indicative planning estimate, not a rental appraisal or guaranteed income. Check current listings and ask a local property manager about the specific location, size and condition. Allow for vacancy, maintenance, insurance, rates and other costs.
Do I need council consent in Rangiora & North Canterbury?+
A home up to 70 m² may qualify for the building consent exemption only when all conditions are met. Resource consent has separate requirements. Check Waimakariri District Council flood and planning information, title covenants and regional servicing requirements. For an exempt build, receive the council’s Project Information Memorandum before work starts and submit the required completion documents.
Can I add a home in Pegasus or Ravenswood?+
Check the property title and any subdivision covenants as well as the applicable planning rules. Private restrictions may affect additional dwellings. Available services, hazards and building space also need to be established for the individual section.
What changes on a lifestyle block?+
Longer power, water and wastewater connections can add cost. An on-site wastewater system may need assessment or upgrading. Check access, flood information and title restrictions, then ask the builder to quote all required site work.
How long could construction take in Rangiora & North Canterbury?+
The 9 to 12-week on-site allowance is an estimate. Your builder needs to confirm the programme from the completed plans, ground works, access, service connections, material lead times and availability. Plan preparation and any required council processes are separate from this construction period.
