Granny flats and small homes in Taranaki.
Taranaki includes New Plymouth, Stratford and South Taranaki. A small home may provide a rental, family accommodation or housing for farm staff. Wind, rainfall, coastal hazards and service connections are relevant across the region, with conditions varying by property. Seventy supplies architectural plans adapted to your address. Your chosen licensed builder quotes for construction, and the proposal must meet the relevant national exemption conditions and local requirements.
Building consent and resource consent requirements
Both national reforms apply in Taranaki. Building consent and resource consent are separate requirements. Your project must meet all the relevant conditions to proceed without either.
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 sets these measurements for qualifying detached minor dwellings in Taranaki. District plans 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
Natural hazards, services, title restrictions and other site requirements can affect your project. Confirm which apply to your address.
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 conditions and foundations
Volcanic ash and heavier soils require assessment at the property. Foundation requirements should follow that assessment. Wind and rainfall also affect the construction specification, including structural bracing, roof and wall junctions, guttering and drainage. These requirements need to be included in the builder’s quote.
Taranaki has exposed coastal and ring-plain sites as well as more sheltered urban properties. Wind and rainfall affect bracing, fixings, drainage and exterior details. Ground includes volcanic ash and heavier soils in places. Coastal addresses also need materials suited to salt exposure.
Site restrictions in Taranaki
Council maps help identify potential restrictions. Your designer and council can confirm how they affect the building location, floor level or need for additional reports.
Check coastal-erosion information and relevant requirements in the district plan.
Check flood information for catchments flowing from Taranaki Maunga and any floor-level conditions.
Check applicable volcanic-hazard information around Taranaki Maunga.
Transmission lines and gas infrastructure may require additional building distances or other restrictions.
Local requirements to check
Review these local considerations when planning a project in Taranaki.
Confirm the address-specific wind design so bracing and fixings can be included in the specification and quote.
Size gutters, downpipes and drainage for the property and confirm appropriate roof and wall details.
Check rural boundary distances, wastewater and access. For qualifying NES-DMRU proposals, boundary distances are 10 m front and 5 m sides and rear.
Confirm wastewater treatment and disposal for properties outside public service areas, including rural Stratford and South Taranaki.
Uses for a small home in Taranaki
Potential uses include rentals for people working in New Plymouth’s energy, engineering and healthcare sectors, and family or staff accommodation on rural properties. A farm dwelling still needs suitable access, water and wastewater arrangements. Check the intended use and current demand before relying on rental income.
The New Plymouth rental example is about $570 a week for a two-bedroom home. The simple-site Kōwhai 60 construction estimate starts around $166,000. Wind exposure, rainfall detailing, site work and rural services can change the price. For staff accommodation, assess the full housing cost as part of the business budget.
Steps to plan your project
Review the title, planning requirements and services before construction. Your designer, builder and council can confirm what the project requires.
Check covenants and easements that could restrict a second home, its size, location or access.
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.
