Auckland Unitary Plan Zones: What You Can Build in 2026
Auckland Unitary Plan 2026: What Your Zone Actually Lets You Build Now (After MDRS Was Withdrawn)
Quick answer (as at June 2026): The Auckland Unitary Plan still governs what you can build on your section, but the MDRS “three homes, three storeys without consent” rule was withdrawn on 9 October 2025. Your original zone rules are back in force while Plan Change 120 is worked through.
Most of what you will read online about building or subdividing in Auckland is wrong as of today. It tells you the Medium Density Residential Standards (MDRS, the rules that let you put three homes up to three storeys on most residential sections without resource consent) are live. In Auckland, they are not. The Council pulled them out at 5pm on 9 October 2025. Christchurch did the same. Everywhere else in New Zealand, the MDRS still apply. Here, they do not.
That single change rewrites the answer to the only question most property owners actually care about: what can I build on my section right now? If you have a 700m² site in Henderson and you have been assuming you can drop three townhouses on it as of right, that assumption expired eight months ago.
So here is the honest 2026 picture, written for the decision you are actually trying to make, not as a Council-style plan summary. We will cover what replaced the MDRS, what each residential zone lets you build today, the levers you can pull right now (including the new granny flat exemption), how overlays quietly kill otherwise-good sites, and the call every owner is weighing up at the moment: act under the current rules, or wait for Plan Change 120 to land.
One caution before we start. This area is moving faster than any other part of Auckland planning. We have dated this article and we refresh it on every Plan Change 120 decision. If you are reading a version of this more than three months old, check the live position before you bank on anything here.
Is the MDRS Still in Force in Auckland, and What Replaced It?
No. The MDRS was withdrawn in Auckland on 9 October 2025. What governs your section today is the original Auckland Unitary Plan, the single planning rulebook that sets out every zone and development rule across the region.
How we got here, briefly
The MDRS arrived through Plan Change 78 (PC78) in 2022, imposed on Auckland by central government. The Council never wanted it, arguing it forced density onto floodplains and sites with no infrastructure to support them. After the 2023 floods, that argument won. A 2025 amendment to the Resource Management Act (the Resource Management (Consenting and Other System Changes) Amendment Act 2025) gave the Council the power to withdraw PC78 and write a replacement, as long as the replacement enabled at least the same housing capacity.
That replacement is Plan Change 120 (PC120): Housing Intensification and Resilience, notified on 3 November 2025. Submissions closed on 19 December 2025, with more than 10,500 lodged. PC120 shifts growth towards rapid transit, the City Rail Link and town centres, and away from flood and hazard land.
🏠 Development tip: One part of PC120 already bites. Its natural hazard provisions took immediate legal effect on notification (3 November 2025) under section 86B of the RMA. So flood and coastal hazard controls can restrict your site today, even though the rest of PC120 is still in submissions.
The capacity number keeps shrinking
Here is the part that has moved since most guides were written. PC120 as notified was modelled to enable roughly two million homes. In February 2026 the Government signalled cutting that floor to 1.6 million. Then legislation passed in April 2026 reduced the minimum required capacity again, to approximately 1.4 million homes, a cut of around a third. Officials estimate the plan will still enable close to 1.6 million once mandatory rules near the City Rail Link are counted.
Capacity is a theoretical figure, not a build target. But the direction of travel matters for you: less blanket upzoning, more density concentrated near transit, and tighter rules on hazard land.
Important: PC120 is not settled. The Council endorsed two zoning scenarios for feedback in June 2026, with a committee decision on amendments due July 2026 and a second public submission round expected around August 2026. Final decisions are due by mid-2027. Check the live status on Auckland Council’s PC120 page before relying on any figure here.
Which brings us to the question that actually pays the bills.
What Your Residential Zone Actually Allows You to Build in 2026
With the MDRS gone and most of PC120 not yet operative, your development potential is set by the original Auckland Unitary Plan zone your section sits in. There are four residential zones, and the gap between them is enormous. Step one for any owner is the same: find your zone and your overlays on the Auckland Council “what can I do in my zone” tool. Step two is understanding what that zone permits before you fall in love with a layout your site cannot legally hold.
The four zones, from least to most development potential
Single House Zone is the most restrictive. It permits one principal dwelling per site, with a minor dwelling possible subject to size limits, and a building height of around 8m (roughly two storeys). This is the zone over much of Auckland’s established, leafy and character-heavy suburbs. If you own here and you are dreaming of townhouses, the honest answer is usually: not without a significant resource consent fight, and often not at all.
Mixed Housing Suburban (MHS) is a two-storey zone (about 8m), generally allowing up to two dwellings before you trip into resource consent territory, with more possible on merit. Height in relation to boundary is 2.5m. This covers a lot of suburban Auckland: Massey, Te Atatu, Onehunga, Avondale.
Mixed Housing Urban (MHU) is the workhorse for infill. It is a three-storey zone (about 11m) built for terraces and low-rise, and it sits over development suburbs like Mt Albert, New Lynn, Henderson, Papatoetoe and Manurewa. Height in relation to boundary lifts to 3m. This is where most viable small townhouse projects in Auckland are happening.
Terrace Housing and Apartment Buildings (THAB) is the highest-density residential zone, built for terraces and apartments, with an operative height around 16m (commonly five to seven storeys). It clusters near centres and transit. PC120 proposes lifting THAB heights to around 22m in walkable catchments, but that is proposed, not operative.
| Zone | Typical scale (operative AUP) | Realistic development lens |
|---|---|---|
| Single House | 1 dwelling, ~8m / 2 storeys | One home, possibly one minor dwelling. Low intensification. |
| Mixed Housing Suburban | ~2 storeys, ~8m, HIRB 2.5m | Up to ~2 dwellings before consent; more on merit. |
| Mixed Housing Urban | 3 storeys, ~11m, HIRB 3m | Best zone for small townhouse infill. Most projects need consent for 3+ dwellings. |
| THAB | ~16m, 5-7 storeys | Terraces and apartments. PC120 proposes ~22m near transit (not operative). |
The figures above are the broad operative position; exact dwelling counts, site coverage percentages and subdivision minimums vary by site and must be confirmed against the relevant Auckland Unitary Plan chapter before you commit. We confirm yours as part of a feasibility assessment, because a 50mm miss on height in relation to boundary can turn a permitted build into a non-complying one.
Important: Your zone is only half the answer. Overlays sit on top of zones and can override them entirely. Heritage and special character overlays, flood and coastal hazard areas, and significant ecological areas all restrict what you can build regardless of your zone. Check overlays on the Auckland Council zone and overlay maps before anything else.
If your section is the right zone but you want to know how to actually fit compliant homes within these envelopes, that is a design question. Our architecture partner, Sonder Architecture, covers how to design within the current rules in detail. We focus on whether the development stacks up in the first place.
So what can you do right now, today, without waiting for any of this to settle?
Can I Add a Dwelling or Subdivide Under the Current Auckland Unitary Plan?
Yes, on the right site. The MDRS withdrawal did not stop development in Auckland; it just removed the blanket shortcut. Three levers are live right now.
The 70m² granny flat exemption is the biggest quiet win of 2026
Since 15 January 2026, you can build one new detached, single-storey, self-contained dwelling up to 70m² on a residential or rural section without a building consent and without a resource consent, provided you meet the conditions. This came in under the Building and Construction (Small Stand-alone Dwellings) Amendment Act 2025.
It is not a free pass. The work is Restricted Building Work (RBW, work that must be done or supervised by a Licensed Building Practitioner, an LBP, under the Building Act). You still need a Project Information Memorandum (a PIM, the Council’s pre-build report on your site) before you start, and you must notify the Council on completion. The dwelling must meet the Building Code, sit roughly 2m from boundaries and other buildings, and have its own utility connections. Build in a flood zone and you will still need to lift the floor above the flood level. We cover the detail in our minor dwelling feasibility guide.
🏠 Development tip: A 70m² consent-exempt unit on a Mixed Housing Urban section in Papatoetoe can add a rentable second income without the consent timeline or cost of a full multi-unit project. For owner-occupiers sitting on a large section, it is often the highest-return move available right now.
Subdivision still works, the old way
Subdivision in Auckland runs through the operative Unitary Plan and needs a resource consent (the Council’s permission to use or divide land, separate from a building consent). The minimum site sizes and rules depend on your zone and overlays. The withdrawal of the MDRS changed the upzoning picture, not the subdivision pathway. If your section was good to subdivide in 2024, it almost certainly still is, subject to the hazard controls now biting. We walk the process and costs through our Auckland subdivision service, part of the wider develop with us programme.
One of our development clients in Manurewa held a Mixed Housing Urban site they had assumed needed the MDRS to work. It did not. The operative MHU rules carried a three-unit scheme on their own, once we ran the height in relation to boundary and outlook numbers. The MDRS withdrawal cost them nothing. Sound familiar? A lot of owners are sitting on viable sites they have written off on bad information.
Important: The granny flat exemption removes the consent, not the obligations. You still pay any Auckland Council development or infrastructure contributions that apply, your trades must be licensed, and overlays still rule. For the official conditions, see the LBP exemption notice and MBIE’s guidance.
Which leaves the question every owner with development plans is actually losing sleep over.
Should I Act Under the Current Rules Now, or Wait for Plan Change 120?
The honest answer: for most owners, the current rules are the safer bet, and waiting carries real downside. PC120 is more likely to reduce your development potential than increase it, unless you sit near a rapid transit station.
Why waiting is risky for most sites
The capacity target has been cut from two million to around 1.4 million homes. The two scenarios the Council is weighing both pull intensification back from suburban areas and concentrate it near transit and centres. Both also add stronger hazard controls and downzone the most flood-prone land. If your section is more than about 10km from the city centre and not near a busway or train station, PC120 is trending towards less density on your site, not more. Special character protections are also being retained or strengthened, which hits owners in suburbs like Mt Eden, Epsom and Ponsonby hardest.
Where waiting might pay off
The clear exception is land within walking distance of the five Western Line stations the Government has locked in for upzoning ahead of the City Rail Link opening this year: Maungawhau, Kingsland, Morningside, Mount Albert and Baldwin Avenue. If you own there, more height is coming and may be worth waiting for. Everywhere else, the rules you have today may be the best rules you will get.
“We are telling owners the same thing in every feasibility meeting at the moment: do not wait for PC120 to rescue a marginal site. For most of Auckland it tightens the rules, it does not loosen them. If your section works under the current Unitary Plan, the cleanest play is usually to move while you can.”

There is one more reason the current rules matter. The April 2026 legislation included transitional protection for roughly 400 developers and owners who had projects consented or already in the building consent process under the MDRS between 18 August 2022 and 9 October 2025. If you started under the old rules, your project can continue. If you were thinking about it but never lodged anything, that window has closed.
None of this is a reason to rush a bad site. The truth is, not every section is worth developing, and we would rather tell you that upfront than six months and $40,000 of consultants in. But a good site under today’s rules is a known quantity. A good site under PC120 is a guess until at least mid-2027. We work through that exact call on the develop with us side of the business every week.

Is MDRS still in force in Auckland in 2026?
No. The Medium Density Residential Standards were withdrawn in Auckland on 9 October 2025 when the Council partially withdrew Plan Change 78. The MDRS still apply in the rest of New Zealand, but in Auckland the original Auckland Unitary Plan zone rules are back in force while Plan Change 120 is worked through. The old shortcut of three dwellings up to three storeys without resource consent no longer applies here.
What can I build on my section under the Auckland Unitary Plan now?
It depends on your zone. Single House Zone allows one principal dwelling plus a possible minor dwelling. Mixed Housing Suburban allows around two dwellings at two storeys before resource consent. Mixed Housing Urban allows three-storey terraces and is the main infill zone. THAB allows apartments up to around 16m. Overlays such as heritage, flood and coastal hazard can override your zone, so always check the Auckland Council planning maps first.
What is Plan Change 120 and how could it change my development potential?
Plan Change 120 (Housing Intensification and Resilience) is the Council's replacement for the withdrawn MDRS, notified on 3 November 2025. It concentrates intensification near the City Rail Link, rapid transit and centres, and tightens rules on flood and hazard land. Its required capacity was legislated down to about 1.4 million homes in April 2026. For most suburban sites away from transit, PC120 trends towards less density, not more.
How do I find out my Auckland zone and overlays?
Use the Auckland Council Unitary Plan online maps. Enter your address to see your residential zone (Single House, Mixed Housing Suburban, Mixed Housing Urban or THAB) and any overlays such as special character, heritage, flood plain or coastal inundation. Overlays sit on top of zones and frequently restrict development more than the zone alone suggests, so never assess a site on its zone in isolation.
Can I build a granny flat without consent in Auckland in 2026?
Yes. Since 15 January 2026, you can build one detached, single-storey, self-contained dwelling up to 70 square metres without a building consent or resource consent, under the Building and Construction (Small Stand-alone Dwellings) Amendment Act 2025. The work must be done or supervised by Licensed Building Practitioners, meet the Building Code, and you must obtain a Project Information Memorandum from the Council before starting and notify them on completion.
Should I develop now or wait for Plan Change 120?
For most Auckland sites, the current rules are the safer option. PC120 cuts overall capacity and pulls density back towards transit and centres, so suburban sites away from train and busway stations generally face tighter rules, not looser. The exception is land near the five Western Line City Rail Link stations, where more height is coming. A site that works under today's Unitary Plan is a known quantity; PC120 outcomes are uncertain until at least mid-2027.
What is the difference between Mixed Housing Suburban and Mixed Housing Urban?
Mixed Housing Suburban (MHS) is a two-storey zone (around 8m) allowing roughly two dwellings before resource consent, with a 2.5m height in relation to boundary. Mixed Housing Urban (MHU) is a three-storey zone (around 11m) built for terraces and low-rise, with a 3m height in relation to boundary. MHU offers materially more development potential and is where most viable small townhouse projects in Auckland happen.
Do I still need resource consent to subdivide in Auckland?
Yes. Subdivision runs through the operative Auckland Unitary Plan and requires a resource consent, which is the Council's permission to divide land, separate from a building consent. Minimum site sizes and rules depend on your zone and overlays. The withdrawal of the MDRS changed the upzoning rules, not the subdivision pathway, so a site that was viable to subdivide before generally still is, subject to the hazard controls now in effect.
Were any Plan Change 120 rules already in legal effect in 2026?
Yes. While most of PC120 is still in submissions, its natural hazard provisions took immediate legal effect on notification, 3 November 2025, under section 86B of the Resource Management Act. This means flood and coastal hazard controls can restrict what you build on an affected site today, even though the wider intensification rules are not yet operative. Check your site on the Auckland Council maps before relying on any general zone guidance.
What happens to projects started under the MDRS before it was withdrawn?
The legislation passed in April 2026 included transitional protection for roughly 400 developers and property owners whose projects were consented or already in the building consent process under the MDRS between 18 August 2022 and 9 October 2025. Those projects can continue. If you had not lodged anything before the 9 October 2025 withdrawal, the MDRS pathway is no longer available and your zone's operative rules apply.
