Almost every residential block in Canberra can now take more than one home. Whether it stacks up depends on a suburb by suburb charge schedule that changed on the same day.

On 1 July 2026, Major Plan Amendment 04 to the Territory Plan commenced. It made low rise medium density housing permissible across the RZ1 Suburban and RZ2 Suburban Core zones, which between them cover the overwhelming majority of Canberra’s residential land. Duplexes, triplexes, terraces, townhouses and low rise apartments are now on the table in suburbs that were effectively limited to one house per block.

That is the change that got reported. The change that will actually determine which blocks get built on landed the same day, in a different document, and has had almost no coverage.

It is called the Planning (Lease Variation Charges) Determination 2026. It sets what a lessee pays for the right to put extra homes on a block, and it does so suburb by suburb.

In Greenway, adding a second dwelling attracts a charge of $52,500. In Forrest, the same second dwelling attracts $346,000.

Same reform. Same two homes. Nearly seven times the charge.

What did the missing middle reforms actually change?

According to the ACT Government’s Missing Middle Housing Reform Snapshot, RZ1 makes up 79.7 per cent of Canberra’s residential land, with RZ2 accounting for a further 12.9 per cent. Between them that is more than nine in every ten residential blocks in the city.

Under MPA-04, both zones now permit missing middle housing. RZ1 is capped at two storeys plus an attic. RZ2 goes to three storeys plus an attic.

Several long standing barriers came out at the same time:

• Minimum block size thresholds that limited secondary residences and co housing have been removed
• Subdivision of RZ1 blocks is now permitted, and can occur without first building a dwelling where minimum block sizes are met
• Consolidation of RZ1 blocks is now permitted for any development that increases dwelling numbers
• Block density assessment requirements that capped dwelling numbers are gone, replaced by density targets and design performance standards

Consolidation is guided rather than capped. The Subdivision Technical Specifications set indicative limits of 3,000 square metres for end of section consolidations, 2,500 square metres where a site adjoins urban open space or the community path network, and 2,000 square metres everywhere else. The ACT Government has described these as guidance points rather than mandatory ceilings, which means a larger consolidation can still be approved where the assessment outcomes are met.

Plenty stayed put. Site coverage for multi units in RZ1 and RZ2 remains at 45 per cent. Maximum building heights, principal private open space specifications, minimum dwelling sizes for one and two bedroom homes, cross ventilation and tree planting specifications all survive.

Running alongside the planning change is the Canberra House Pattern Book, a $1 million investment over two years from 2026-27 to produce pre approved architect designed plans for dual occupancy, tri occupancy, townhouse and terrace homes up to two storeys. The designs are being written to be compatible with Modern Methods of Construction, which is the detail worth watching if you are already building offsite or in panel.

What is the Lease Variation Charge?

Canberra runs on leasehold, not freehold. Every block is held under a Crown lease with a purpose clause that sets what the land can be used for and, usually, how many dwellings are permitted on it.

If you want to put more homes on a block than the lease allows, you have to vary the lease. The Lease Variation Charge is what you pay for that variation. Under the Planning Act 2023 it is set at 75 per cent of the added value the variation creates.

For standard variations the charge is codified, meaning it is read off a published schedule rather than valued case by case. It is charged per additional dwelling, and the rate depends on the suburb and on the total number of dwellings approved on the site after the variation.

The charge has existed in one form or another since 1970, previously as a betterment levy and then a change of use charge. It is how the Territory captures rezoning uplift rather than leaving all of it with the landholder.

How much is the Lease Variation Charge per dwelling?

Two schedules matter for residential work, and which one applies to your block is decided by the wording of the lease, not by the suburb.

Schedule 1 covers leases that permit residential use without specifying a number of dwellings. To specify a number, which is what enables unit titling, the charge is $49,000 for each dwelling. That figure rose from $46,000 on 1 July 2026 and sits on a path towards $55,000 set out in the 2023-24 ACT Budget.

Schedule 2 covers leases that do cap dwelling numbers, using wording such as single dwelling housing or not more than two dwellings. Here the charge is the number of additional dwellings multiplied by a rate drawn from a table of 103 Canberra suburbs, banded by the total number of dwellings approved on the site once the variation is done.

The spread across that table is enormous. For a site ending up with two dwellings, the rate runs from $52,500 in Greenway at the bottom to $346,000 in Forrest at the top. Yarralumla sits at $281,250, Red Hill at $265,000, Griffith at $258,750 and Deakin at $257,000. Down the other end, Chisholm, Gilmore and Macarthur sit at $64,500, with Gordon and Kambah at $65,000.

Where the Schedule 1 charge applies, it displaces the Schedule 2 rate. On an inner south block that single distinction is worth hundreds of thousands of dollars, and it is the first thing to establish before pricing anything.

There is relief, and it is time limited. A 50 per cent reduction now applies to standard chargeable variations in RZ1 and RZ2 that add one or more dwellings. To qualify, an application to defer the charge must be made on or after 10 June 2026 and approved, the development application for the variation must be approved before 30 June 2029, and a certificate of occupancy must be issued for each additional dwelling by 31 December 2030. The instrument delivering the reduction expires on that same date.

Those are hard deadlines, not indicative ones. A project that runs long loses the reduction outright.

Why the zoning map and the charge schedule point in opposite directions

Here is the structural tension sitting underneath the whole reform.

Research put to the Legislative Assembly’s Standing Committee on Environment and Planning by the University of Canberra’s Health Research Institute found that roughly 70 per cent of RZ1 blocks currently have low access to local destinations, defined as fewer than four shops or services within an 800 metre walk.

The Institute’s point was that the suburbs with the best walkable amenity, largely the inner north and inner south, are precisely the suburbs carrying the highest Lease Variation Charge. The suburbs with the least amenity carry the lowest.

The charge is doing exactly what it was designed to do. It tracks land value, and land value tracks amenity. But the practical effect is that the economics of the reform push medium density towards the parts of Canberra least equipped to absorb it, and away from the parts best equipped to support it.

For a builder that is not an abstraction. It tells you where the feasible jobs are going to sit over the next three years. It also tells you the inner suburbs will stay hard unless the charge itself changes, which is why the committee recommended an independent review of the Lease Variation Charge to rebalance value capture against actual delivery. The ACT Government response to that report is due on 30 August 2026.

The sliding scale rewards scale, and scale triggers a licence

Because the Schedule 2 rate steps down as the total dwelling count rises, consolidation changes the arithmetic in a way that is easy to miss.

Take three adjoining blocks in Kambah, each with one house on it.

Built as three separate duplexes, each block goes from one dwelling to two. The Kambah two dwelling rate is $65,000. Three variations, three additional dwellings, $195,000 in charge.

Consolidate those same three blocks and build eight townhouses, and the picture changes. Five additional dwellings at the five to ten dwelling rate of $45,750 comes to $228,750. That is more charge in total, but it is 30 per cent less per additional dwelling and it delivers 67 per cent more homes on the same land.

The charge schedule is telling builders to go bigger. The licensing regime is saying something more complicated.

From 1 October 2026, a property developer licence is mandatory under the Property Developers Act 2024 for anyone applying for development approval, arranging for building work at building approval or certificate of occupancy stage, or selling residential property off the plan, on any project of three or more dwellings. Single dwellings and dual occupancies are expressly excluded.

So the threshold that unlocks better charge rates is the same threshold that pulls a project into developer licensing. For a builder who has been comfortable doing dual occupancies, the third dwelling is where the compliance picture changes shape.

Getting licensed is not a formality. Applicants need a rating report from an approved rating entity, and Equifax is currently the only one, delivered through its iCIRT product. The 2026-27 fees are $1,036 for an initial online application, then $1,036 per year for the licence or $7,252 for a seven year term paid upfront, plus an activity based fee of $518 per dwelling payable when building approval is issued. Registered community housing providers are exempt from the activity based fee.

The scheme also carries rectification orders for serious defects, which can be issued up to ten years after building work is completed. That is a long tail, and it belongs in the risk conversation before the third dwelling goes on the plan, not after.

What the RZ2 experience says about timing

Canberra has run a version of this experiment before.

RZ2 land around local shops and group centres was upzoned in 2003 and 2004 to allow greater density. More than twenty years on, ACT Government data provided to the Assembly committee shows that 85 per cent of RZ2 land is still made up of single detached dwellings. Duplexes account for one per cent. Multi unit or unit titled housing accounts for 9.5 per cent.

The committee noted that no analysis had been done to understand why uptake was so limited before the new reforms were designed, and recommended that work be undertaken.

That history is worth holding onto, for two reasons.

The first is timing. Permission is not a pipeline. Blocks redevelop when the lessee decides to sell or build, and most Canberrans are not sitting on a redevelopment plan waiting for a zoning change. This will move over years, not months, and anyone forecasting a rush of work in the next two quarters is likely to be disappointed.

The second is positioning. A reform that most landholders will not act on quickly is a reform with limited early competition. The builders who understand the charge schedule now will be able to price jobs that others cannot yet see.

What to check before you price a missing middle job in Canberra

Read the Crown lease purpose clause first

Whether the block falls under Schedule 1 at $49,000 per dwelling or under the Schedule 2 suburb rate is determined by that clause, and the gap can be six figures on the same piece of dirt. If the lease wording is ambiguous, the Development Assessment Leasing Team can confirm which schedule applies before you commit to a number.

Look up the suburb rate and the dwelling band together

The rate is not one number per suburb. It steps down as the total approved dwelling count rises, which means the yield decision and the charge decision are the same decision. Work them out at the same time or you will price the job twice.

Map the reduction deadlines against the programme

Development approval before 30 June 2029 and a certificate of occupancy by 31 December 2030 are both required, and both are absolute. On a consolidation with a long approvals path, that window is tighter than it first looks.

Settle the licence question before the third dwelling

If a scheme crosses three dwellings, someone in the chain needs a property developer licence from 1 October 2026. The rating report takes time to obtain, so this is a decision to make at concept stage rather than at building approval.

Watch the supporting legislation

The Planning (Missing Middle Housing) Amendment Bill 2026 is still before the Legislative Assembly. If it passes, it would make certain lease variations exempt development, removing the need for a development application just to vary the lease, and would take small subdivision and consolidation applications out of the significant development category. A development application would still be required for design and siting. Until it passes, the current pathway applies.

The Good Builder Take

The zoning map got the headlines. The charge schedule will decide the jobs.

Canberra has just made medium density legal across more than nine in every ten of its residential blocks, and then set the price of using that permission suburb by suburb. Anyone pricing this work off the zoning change alone is going to get it wrong, in both directions. Some blocks are far more viable than the coverage suggests. Others are not viable at all.

The practical read is straightforward. Early volume will sit in the middle and outer suburbs where the charge is manageable. Consolidation beats single block duplexes on a per dwelling basis. And the third dwelling is where developer licensing starts, which makes it a business decision rather than a design one.

Get the lease wording checked and the licence question settled before the first quote goes out. Everything else follows from those two answers.
