A proposal, not a rule change — yet
A building consent exemption for small standalone dwellings is proposed. It is not law. It is targeted to take effect in 2026, which means it has not happened yet and there is no confirmed date. Until it takes effect, every small standalone dwelling still needs a building consent, exactly as it does today. If you are pricing, scheduling, or advising on a job right now, treat this as unchanged.
That framing matters more than any other line in this post, so it is worth being blunt about it: acting as though the exemption is already in force, on the strength of an article like this one, is the kind of mistake that costs real money. We are not going to dress a proposal up as a rule.
What the proposal describes, based on the Licensed Building Practitioners (LBP) scheme’s own update, is an exemption from the consent process for dwellings that meet a specific set of conditions:
- The dwelling is a standalone building up to 70 square metres.
- It has a simple design.
- It still has to meet the Building Code — the exemption is from the consent process, not from the standard the building is built to.
- The work has to be carried out or supervised by the relevant licensed tradesperson.
- The homeowner has to notify their local council before construction begins, and again after it’s completed.
That is the full list of criteria as described in the source. We are not going to interpret any of it further, and we are not going to speculate about edge cases, timelines beyond “targeted for 2026,” or how a particular council might apply it. If you want to know whether a specific job would qualify, or what “simple design” would mean for your plans, that is a question for your local council or the Licensed Building Practitioners scheme, not for us. We are not qualified to advise on building consent, design, or Building Code compliance, and we are not going to pretend otherwise. This article is about something else entirely: what a change like this could mean for the enquiries landing on a builder’s front desk, if it happens.
Why this is an enquiry story, not a building-code story
Here is the reasoning, laid out plainly so it is clear where the facts stop and the thinking starts.
Right now, building consent is part of what shapes a small-dwelling enquiry before it ever reaches a builder. A homeowner planning a sleepout, a minor dwelling, or a small standalone build knows — or finds out early — that consent is part of the process. That tends to filter who actually picks up the phone or fills out a form: people who have looked into it a bit, who understand there’s a process ahead, and who are further along in deciding whether they’re serious about the job.
If a dwelling up to 70 square metres no longer needs to go through that consent process, one obvious effect is that the step which used to slow some enquiries down, and nudge some people toward doing more homework first, would no longer apply to jobs of this size. We think it is reasonable to expect that could change three things about the enquiries builders receive for small dwellings:
More of them. Removing a process step that some homeowners find slow or intimidating plausibly makes a small dwelling feel like a more approachable project to start asking about. More people considering the idea reasonably means more people making contact.
Faster-arriving ones. Some enquiries that might currently wait until a homeowner has looked into consent requirements, spoken to a designer, or done more planning could arrive earlier in that process instead — because there’s less to work through before picking up the phone.
Less prepared ones. An enquirer who has not had to think about consent yet may not have thought through size limits, design simplicity, or what “meets the Building Code” actually requires in practice. They may not know the difference between “no consent needed” and “no rules apply.” Some of that early education may end up landing on whoever answers their enquiry first.
We want to be honest about what this is: reasoning about how a process change plausibly affects enquiry behaviour, based on nothing more than that reasoning. It is not a prediction, and it is not backed by a study, a survey, or a statistic about homeowner behaviour — we don’t have one to point to, and we would rather say so than borrow a number from somewhere else to make the argument look more solid than it is. Read it as “here’s a plausible effect worth planning for,” not “here’s what will happen.”
Where that lands, if it plays out
None of what follows is compliance advice, and none of it touches on whether a job needs consent. It’s about what happens at the front desk if enquiry volume, timing, or preparedness shifts the way we’ve reasoned through above.
More enquiries to triage. A busier stream of small-dwelling enquiries is still a stream that needs answering, sorting into real jobs versus early browsing, and following up. That’s true whether the exemption changes anything or not — it’s just a bigger version of the same job.
Enquiries that need more up-front conversation. If some enquirers arrive earlier and less prepared, the first response matters more, not less. A prompt, clear reply that captures what the person actually wants, rather than a slow one that lets them drift to the next builder on their list, is the same discipline this site talks about everywhere else — it just applies to a potentially larger group of people.
More jobs where “what was said, and when” matters. A written, timestamped record of an enquiry and what was discussed is useful on any job. It becomes more useful, not less, when more of your enquiries are coming from people who are still working out what they actually need.
This is squarely a front-desk problem: capturing enquiries, replying quickly, and not losing track of who asked what. It is not a reason to start advising homeowners on consent, and we would not do that even if asked. If a homeowner or a builder wants to know whether a specific dwelling would qualify for the exemption, or what “simple design” means in practice, that question belongs with the local council or the Licensed Building Practitioners scheme — not with us, and not with this article.
If you want the general version of this, not tied to any single proposed rule change, our guide on handling trade enquiries covers capturing, replying to, qualifying, and following up on enquiries as they come in, whatever is driving the volume. For a worked example of what happens when enquiries go unanswered in the meantime, see the missed-call flow. And if you want the wider context this proposal sits inside, we’ve rounded up the other changes moving through the building and construction sector in our overview of the 2026 trade rule changes.
The honest summary
The 70 square metre consent exemption is proposed, not law, and targeted for 2026 with no confirmed date yet. Until it takes effect, every small standalone dwelling still needs a building consent. If it does take effect, we think it is reasonable to expect it will change the volume, timing, and preparedness of small-dwelling enquiries — but that is our reasoning about how the change would plausibly play out, not a forecast, and we are not qualified to say anything more about the rule itself. For that, talk to your local council or the Licensed Building Practitioners scheme.
What we can help with, if and when the enquiries start behaving differently, is the same thing we help builders with today: catching every enquiry, replying to it fast, and making sure none of it goes quiet while you’re on the tools.
