Building Consent NZ: What It Means for Your Auckland Build
Quick answer: A building consent is Auckland Council’s written approval to start construction. Almost every new home in NZ needs one — but from 15 January 2026, a qualifying standalone dwelling up to 70m² can be built without a building consent.
The rules changed in January. If you’ve read an older guide on building consent in NZ, some of it is now wrong — and the part that changed is the part most people get excited about. Since 15 January 2026, you can build a single-storey, detached dwelling up to 70m² without a building consent, provided it meets the conditions and a Licensed Building Practitioner designs or supervises it. That’s a genuine shift, not a tweak.
For a full-size new home, though, nothing has changed. You still need a building consent (council’s permission for the actual construction work to proceed) before a single pile goes in the ground. And most people building in Auckland don’t really want a recital of the Building Act. They want to know what the consent means for their build: how long it holds things up, what it costs, why it sometimes blows out by months, and whether any of that is avoidable.
That’s what this guide covers. We manage Auckland consent applications week in, week out, for families building in Flat Bush and Hobsonville Point, and for developers putting townhouses on Mixed Housing Urban sites in Henderson and Mt Albert. So this is the builder’s view, not the rulebook’s. We’ll walk through when you actually need a consent, the difference between a building consent and a resource consent (they’re not the same thing, and the mix-up costs people real money), how the application works, what the fees and levies add up to, and the single biggest cause of delay — the one you can control.
One honest note before we start. Consent rules in NZ are moving fast right now. The granny flat exemption, the withdrawal of the medium-density rules in Auckland, levy changes mid-2026 — it’s a lot of moving parts. Where something is still settling, we’ll say so rather than pretend it’s locked in.
Do You Need a Building Consent to Build a New Home in Auckland?
For a standard new house, yes. Every full-size new home in New Zealand needs a building consent — the council’s formal permission for the construction work itself, issued under the Building Act 2004. It confirms your plans meet the New Zealand Building Code: the minimum standard for things like structure, weathertightness, fire safety, and drainage. No consent, no legal build.
The short answer for a full new build
If you’re building a three-bedroom home in Karaka, a two-storey family house in Long Bay, or anything resembling a normal dwelling, you’re in consent territory. That takes in almost every one of the new homes we design and build. The work has to be carried out or supervised by a Licensed Building Practitioner (LBP) — a tradesperson certified to do or oversee Restricted Building Work (RBW), which is the structural and weathertightness work that keeps a house standing and dry. Your builder and designer will usually hold the LBP licences that matter.
The new 70m² exemption — and where it stops
Here’s the part that changed. From 15 January 2026, a new building consent exemption lets you build certain new, single-storey, standalone dwellings up to 70m² without a building consent, provided every condition is met and the work is carried out or supervised by licensed building professionals, according to the Ministry of Business, Innovation and Employment (MBIE). The build still has to comply fully with the Building Code. You don’t get to skip the standard — you skip the consent paperwork.
It’s not as consent-free as the headlines suggest, though. You still have to apply for and receive a Project Information Memorandum (PIM), a council report on what affects your site, before work starts, and notify the council once you’ve finished, with final plans, Records of Work, and certificates of compliance. And a development contribution may still apply, payable within 20 working days of completing the build. The exemption is real and useful for a minor dwelling out the back. It is not a free pass for a full home.
Important: The 70m² exemption has tight limits — single storey, detached, simple design, built or supervised by an LBP, and full Building Code compliance. Step outside any of them and the standard consent process applies. Check the conditions on MBIE’s granny flats exemption guidance before you commit to a design.
What Schedule 1 already covered
The 70m² exemption sits alongside the older list of exempt work in Schedule 1 of the Building Act — minor, low-risk jobs like a small garden shed or like-for-like repairs. That list never applied to new homes, and it still doesn’t. The genuine change for 2026 is the standalone-dwelling exemption, not anything in the old Schedule 1.
So before you assume your project needs a consent, or that it’s exempt, get the scope confirmed. That’s the first thing we do on any job, because it sets the whole timeline. It also leads straight into a question people muddle constantly: building consent versus resource consent.
? Development tip: If you’re considering a minor dwelling under the new exemption, design to the 70m² limit from day one. Retrofitting a too-big design back under the threshold is harder and more expensive than starting within it. Our team can scope this against your section as part of the building process.
Building Consent vs Resource Consent — What’s the Difference?
This is the distinction that trips people up most, and getting it wrong can cost you weeks. A building consent is permission for the construction work; a resource consent is permission to use the land in a particular way. They come from different parts of the law, they’re assessed against different rules, and plenty of new builds need both.
Building consent, in plain terms
A building consent asks one question: will the thing you’re building meet the Building Code? It’s about the structure itself — foundations, framing, weathertightness, plumbing, fire safety. It’s issued under the Building Act 2004 and processed by Auckland Council acting as the building consent authority.
Resource consent, in plain terms
A resource consent is different. It asks whether you’re allowed to do what you’re proposing on that piece of land. It’s issued under the Resource Management Act 1991 and assessed against the Auckland Unitary Plan, the single planning document that sets zoning and development rules across the region. If your build breaches a zone rule (too tall, too close to the boundary, too much site coverage), you’ll likely need a resource consent on top of your building consent.
| Building consent | Resource consent | |
|---|---|---|
| What it approves | The construction work itself | The use of the land |
| Governing law | Building Act 2004 | Resource Management Act 1991 |
| Measured against | NZ Building Code | Auckland Unitary Plan |
| When you need it | Almost every new build | When your design breaches a zone rule |
The Auckland zoning picture has shifted
If you’ve read older advice, you might have seen that the Medium Density Residential Standards (MDRS), rules that let you put up to three dwellings of up to three storeys on most residential sites without a resource consent, applied across Auckland. That’s no longer the case. Auckland Council withdrew Plan Change 78 and removed the MDRS as a permitted activity on 9 October 2025, and many properties have reverted to their original Auckland Unitary Plan zoning. The Council notified a replacement, Plan Change 120, in November 2025, but its full effect is still working through, on a timeframe of around late 2027, with outcomes not guaranteed.
What that means for you in mid-2026 is simple: don’t assume blanket three-dwelling rights — check your operative zone before you design. A site in Mt Albert that looked like a townhouse play under the old rules might sit under different rules today. For developers especially, this is the first feasibility question, not a detail to sort later. Our development process starts exactly here.
What can you build on your Auckland section?
Two documents decide it. Your Auckland Unitary Plan zone sets what you’re allowed to build (how many dwellings, how tall, how close to the boundary), and the Building Code sets how it has to be built. The building consent is simply the council’s sign-off that your plans meet that second one. So “what can I build on my land” is really a zoning question first and a consent question second.
The quickest way to check is Auckland Council’s online GeoMaps viewer, which shows your property’s zone and any overlays such as flooding, heritage, or coastal hazard. Search your address, note the zone, then read that zone’s rules in the Unitary Plan. A Single House Zone section in Epsom and a Mixed Housing Urban section in Henderson can look identical from the street and allow completely different builds. Auckland Council’s building regulations flow from there: the zone rules under the Unitary Plan, the national Building Code, and the consent process that ties the two together.
If the answer isn’t obvious, that’s exactly what a feasibility check is for. We run one at the start of every job, because it decides everything downstream.
Important: Around 12,000 Auckland properties most at risk from natural hazards (roughly 2,000 in floodplains and 10,000 in coastal-erosion areas) are being downzoned to limit intensification under Plan Change 120, the replacement plan the council is still working through rather than a rule that is operative today. Some hazard overlays can still affect a resource consent decision now, so confirm your zoning and any overlays on Auckland Council’s Plan Change 78 page and the Unitary Plan maps before you commit to a design.
There’s one more thread worth pulling. Alongside the building consent exemption, the National Environmental Standards for Detached Minor Residential Units (NES-DMRU) also became law on 15 January 2026, and it can remove the resource consent requirement for a qualifying detached minor unit. The two operate independently — so a small dwelling could be exempt from both, one, or neither, depending on the detail. This is the kind of overlap where our architectural partner, Sonder Architecture, earns its keep at the design stage. Get it right on paper and you avoid a consent you didn’t need to lodge.
? Development tip: The cheapest resource consent is the one you design around. Before you lock plans, check height, height-in-relation-to-boundary, and site coverage against your operative zone. A 200mm change to a roofline has saved our clients a discretionary consent more than once.
How to Apply for Building Consent in Auckland
The application itself isn’t mysterious. The trouble is that “what you submit” and “what gets it through cleanly” are two different lists, and the gap between them is where timelines die. A complete, well-prepared application is the single biggest lever you have over how long consent takes.
Start with a PIM
Before you lodge, you’ll usually get a Project Information Memorandum (PIM) — a council report setting out what affects your site: zoning, hazards like flooding, services, and any special requirements. Don’t confuse it with a LIM (Land Information Memorandum), which is the broader property report buyers order during due diligence. The PIM tells you what the council knows about your section before you build; the LIM is the full official record of the property. For the new 70m² exemption, the PIM is mandatory even though the building consent isn’t.
What a complete application includes
For a new home, expect to submit detailed architectural plans, structural engineering where required, specifications, a site plan, and the relevant Building Code compliance documentation. The description of work needs to be specific — “new 180m² two-storey dwelling with attached garage and associated drainage,” not “new house.” Vague descriptions invite questions, and questions stop the clock. We see this constantly: the application that names everything sails; the one that summarises gets an RFI.
The 20-working-day clock
Once you lodge and pay, Auckland Council has 20 working days to process a building consent application, according to Auckland Council. That’s the statutory maximum, not a promise — and the clock only counts time the application is sitting with the council. The moment they request more information, it stops, and it doesn’t restart until you’ve answered in full. In practice, Auckland residential consents have been running closer to 30 working days through 2025–26 once you account for those pauses. Plan your build programme around the real-world timeframe, not the statutory one.
That’s why we manage lodgement ourselves on the homes we build. A reader prompt for you: have you ever waited on a council and had no idea what the holdup was? Half the time it’s a single missing document. Our project management exists partly to keep that from happening — to lodge clean and chase fast. Which brings us to what it all costs.
? Development tip: Apply for your PIM early, even before final plans. The site information it returns (services, hazards, overlays) can change your design, and it’s far cheaper to learn that on paper than after you’ve engineered to the wrong assumption.
Building Consent Costs, Levies and Fees in Auckland
Consent isn’t free, and the total is made up of a few separate charges that catch people off guard. For a new home, your consent cost is council processing fees plus two national levies plus the Code Compliance Certificate fee at the end. None of them is huge on its own. Together they’re a real line in your budget.
The two national levies
Two value-based levies apply to most new builds. The MBIE building levy is $1.75 (including GST) per $1,000 of building work, and only applies to projects with a declared value of $65,000 or more, per MBIE’s Building Performance team. Every new home clears that threshold, so it always applies — on a $600,000 build, that’s about $1,050. The BRANZ research levy adds $1 per $1,000 of work over $20,000, funding building research through the Building Research Association of New Zealand. On that same $600,000 build, roughly $600.
Worth knowing for 2026: the government has legislation before Parliament to combine these two levies into a single charge, so the way they appear on your consent invoice is likely to change during 2026. The MBIE building levy rate is also due for its routine three-yearly review, so the figure could move. We’ll update this when it does.
Council processing fees and the CCC
Auckland Council’s own fees are largely time-based, charged at staff hourly rates, with fixed-fee options for simpler work and additional charges where specialist engineering or fire review is needed. At the end of the build comes the Code Compliance Certificate (CCC), council’s confirmation that your finished home meets the consent it was granted, which carries its own processing fee. Budget for the CCC from the start; it’s the document that proves your home is legal and it matters at resale and for insurance. Auckland new builds, for context, typically run $3,000–$5,000+ per square metre depending on spec. Consent fees sit on top of that, and we break the full build budget down in our guide to what it costs to build a house in NZ.
? Development tip: Ask for an itemised fee estimate before you lodge, not after. Council processing is time-based, so a complex design with engineering and fire review costs more to assess than a simple one — and knowing that upfront lets you budget the consent properly instead of being surprised by the invoice.
Important: The council assesses the value of building work itself to calculate levies — it won’t simply take a low figure to reduce the levy. Under-declaring your build value to save on levies isn’t a strategy; it’s a red flag that invites a request for information. Use a realistic figure from the start.
“People fixate on the levy figures, but they’re the predictable part. The cost that actually bites is the holding cost of a delayed consent — finance ticking over on a section while you wait on a fixable RFI. Get the application right and the levies are a rounding error next to the time you save.”

Speaking of which — the delay question is the one that matters most, so let’s finish there.
Why Building Consent Applications Get Delayed — and How to Avoid It
Most consent delays aren’t the council being slow. They’re applications going in incomplete. The 20-working-day clock stops the instant the council asks for more information, and a poorly prepared application can turn a three-week process into a three-month one. That’s the honest version most guides skip.
The RFI clock-stop is where months disappear
A Request for Information (RFI) is the council saying “we can’t assess this without more detail.” Each one pauses the clock until you respond in full — and if your answer triggers another question, it pauses again. Two or three rounds of RFI, each with a gap while a designer turns it around, and you’ve quietly lost six weeks. The work was always going to be approved. The time was lost to back-and-forth that a complete application would have avoided.
What a complete application actually looks like
Specific work description. Plans that match the specifications. Engineering where it’s required, lodged with the application rather than promised later. Services and drainage shown clearly. The applications that clear without an RFI are the ones where the council can answer every question from the documents in front of them. That’s it. It’s not luck.
Where infrastructure can add time
One delay that’s outside the consent paperwork: infrastructure. If your development needs new connections, Watercare (Auckland’s council-owned water and wastewater provider) has to confirm capacity, and in some suburbs that check adds weeks. An infrastructure contribution (the fee that helps fund the upgraded pipes, roads, and stormwater a new dwelling creates demand for) can also apply. For a single home it’s usually straightforward. For a multi-unit site in a developer suburb like Papatoetoe or Manurewa, it’s worth checking early.
Where a managed process changes the maths
This is the part we’d back ourselves on. We lodge a lot of Auckland consents, so we know what each processing officer tends to ask, and we front-load the answers. The truth is, you can’t make the council faster — but you can stop being the reason it’s slow. We see the same pattern over and over: a build lodged complete gets consented inside the statutory window, while a comparable application lodged DIY nearby stalls through two or three RFI rounds. Same council, same rules, different preparation.
If a consent feels like the part of building you’re dreading, that’s usually the right instinct that it should be handled by someone who does it daily. That’s exactly what we’re for.
? Development tip: Ask whoever prepares your application one question: “Is anything in here going to draw an RFI?” A good designer or builder will tell you straight. If they can’t, that’s your answer about who should be lodging it.
Building With Confidence in Auckland
Building consent in NZ comes down to a few things that matter: almost every new home needs one, the new 70m² exemption is real but narrow, building and resource consent are different beasts, and the delays you hear horror stories about are mostly preventable. Get the application right and the rest is process. The consent isn’t the enemy — it’s the thing that makes your home legal, insurable, and worth what you paid to build it.
If you’d rather not learn the Building Act the hard way, that’s what we do. We’ll scope your consent, lodge it clean, and keep the timeline honest from the first conversation.

Do I need a building consent to build a new house in Auckland?
Yes. Almost every full-size new home in Auckland needs a building consent — Auckland Council's approval under the Building Act 2004 confirming your plans meet the New Zealand Building Code. The work must be carried out or supervised by a Licensed Building Practitioner. The one new exception, from 15 January 2026, is a qualifying single-storey standalone dwelling up to 70m², which can be built without a building consent if it meets all the conditions.
What is the difference between a building consent and a resource consent?
A building consent is permission for the construction work; it checks your build against the New Zealand Building Code under the Building Act 2004. A resource consent is permission to use the land in a particular way; it checks your proposal against the Auckland Unitary Plan under the Resource Management Act 1991. Many new builds need both: a building consent for the structure, and a resource consent if the design breaches a zone rule like height or site coverage.
How long does building consent take in Auckland?
Auckland Council has a statutory 20 working days to process a building consent application from the point it is accepted. The clock pauses whenever the council requests further information (an RFI) and only restarts once you respond in full. In practice, Auckland residential consents have been running closer to 30 working days through 2025–26. A complete, well-prepared application is the best way to stay near the statutory timeframe.
How much does building consent cost in NZ?
Your consent cost is council processing fees plus two national levies plus the Code Compliance Certificate fee. The MBIE building levy is $1.75 (incl GST) per $1,000 of building work for projects valued $65,000 or more. The BRANZ levy adds $1 per $1,000 of work over $20,000. Auckland Council's own fees are largely time-based at staff hourly rates. On a typical new home the levies alone run to roughly $1,500–$2,000.
Can I build a granny flat without a building consent in 2026?
From 15 January 2026, you can build a qualifying single-storey, detached dwelling up to 70m² without a building consent, provided it meets all the conditions and a Licensed Building Practitioner designs or supervises it. It must still comply fully with the Building Code. You also have to obtain a Project Information Memorandum (PIM) before starting and notify the council on completion, and a development contribution may still apply.
Do I still need a resource consent in Auckland after the MDRS rules were withdrawn?
Possibly. Auckland Council withdrew Plan Change 78 and removed the Medium Density Residential Standards as a permitted activity on 9 October 2025, so many sites reverted to their original Auckland Unitary Plan zoning. The Council notified Plan Change 120 in November 2025, but its full effect is still working through. Whether you need a resource consent now depends on your operative zone and any overlays — check before you design.
What documents do I need for a building consent application?
For a new home, you'll generally need detailed architectural plans, structural engineering where required, specifications, a site plan, drainage details, and Building Code compliance documentation, plus a clear, specific description of the work. The more precise the application, the less likely you are to receive a Request for Information. Incomplete applications are the most common cause of consent delays in Auckland.
What happens if I build without consent in NZ?
Building work that needs a consent but doesn't have one is illegal. Auckland Council can issue a notice to fix, require you to apply for a Certificate of Acceptance, or in some cases require removal of the work, and prosecution and infringement fees can apply. Unconsented work also causes problems at resale, can void insurance, and may stop you getting a Code Compliance Certificate. It's almost always cheaper to consent properly from the start.
What is a PIM and is it different from a LIM?
A Project Information Memorandum (PIM) is a council report on what affects your specific site for a build — zoning, hazards, services, and special requirements. A Land Information Memorandum (LIM) is the broader official record of everything the council holds about a property, usually ordered by buyers during due diligence. You'll typically get a PIM as part of your consent process, and it's mandatory even for the new 70m² exemption.
What is a Code Compliance Certificate (CCC)?
A Code Compliance Certificate (CCC) is the document Auckland Council issues when it's satisfied your finished build meets the building consent it was granted. It's the formal sign-off that your home is legal and complies with the Building Code. You apply for it once construction is complete and inspections have passed. The CCC matters for insurance and resale, so factor its fee and timing into your build from the start.
Do the MBIE and BRANZ levies apply to my new build?
For a new home, yes. The MBIE building levy applies to building work valued at $65,000 or more, and every new build clears that threshold. The BRANZ levy applies to work over $20,000. Both are calculated per $1,000 of declared build value and collected with your consent. Note that the government plans to combine the two levies into a single charge during 2026, so the way they appear on your invoice may change.
What are the building regulations in Auckland?
Auckland's building rules come from two layers. The national New Zealand Building Code, set under the Building Act 2004, is the minimum standard every build must meet for structure, weathertightness, fire safety and the like. The Auckland Unitary Plan sets the local zoning rules for what you can build on a given site. Auckland Council administers both as the building consent authority, processing building consents and, where a zone rule is breached, resource consents. Most new homes engage all three.
