Apartment projects lift approvals as detached-house numbers fall nationwide

Australia approved more homes in September, but the headline recovery concealed a widening split between detached houses and higher-density development.

The Australian Bureau of Statistics said 17,948 dwellings were approved nationally in seasonally adjusted terms, up 5.1% from August. The improvement was driven by private apartments, townhouses and other dwellings excluding houses, where approvals climbed 16.6% to 6,579.

Private detached-house approvals moved the other way, falling 5.3% to 10,432. They declined in every mainland state measured by the ABS, including falls of 7.8% in South Australia, 6% in Victoria, 5.5% in NSW, 5.1% in Queensland and 4.6% in Western Australia.

The figures suggest Australia’s near-term housing pipeline is becoming more dependent on larger and potentially more volatile multi-unit projects. One apartment approval can add dozens or hundreds of proposed homes to a monthly total, while detached housing tends to enter the data in smaller increments.

A rebound, but not across the board

The September increase partly reversed August’s fall, although total approvals remained 0.8% lower than a year earlier.

There was also a large gap between the two main housing categories. Detached-house approvals were 9.6% higher than in September 2025 despite the monthly fall, while non-house approvals were still 20.5% lower over the year despite September’s rebound.

That combination indicates the apartment and townhouse pipeline remains uneven. A strong month does not necessarily establish a sustained recovery, particularly when the category is still well below its level a year ago.

The value of residential building approved also fell. The ABS recorded an estimated $11.06 billion of residential work in September, down 2.8% from August. The value of new residential building declined 3.3%, while alterations and additions edged 0.8% higher.

Approvals are an important early indicator, but they are not completed homes. Approved projects can be delayed, redesigned or abandoned if finance, presales, construction costs or market conditions make them unworkable.

The Property Council of Australia welcomed the overall improvement but argued that governments and the industry still needed to turn approvals into construction. Its response pointed to borrowing, labour, material and post-approval costs as continuing obstacles for projects.

NSW and Victoria move in opposite directions

State results were unusually divided.

NSW recorded 5,322 approved dwellings, a 37.3% monthly increase and its highest total since September 2025, according to the Property Council’s NSW analysis of the ABS release. Apartments and other non-house dwellings accounted for 3,284 approvals, compared with 2,038 detached houses.

Queensland also posted a substantial increase, with total approvals rising 28% to 4,382.

Victoria moved sharply in the opposite direction. Its total fell 28.9% to 3,694 dwellings, even though it retained the largest number of private house approvals among the states at 2,895.

Western Australian approvals fell 8.7%, South Australia declined 3.2% and Tasmania dropped 25.7%.

Monthly approvals can swing because of the timing of major apartment projects. The ABS trend measure, which smooths some of that volatility, was more positive nationally: total trend approvals rose 1.3% to 18,705, including a 3.5% increase for private dwellings excluding houses.

For buyers, the change in housing mix matters as much as the national total. More apartment and townhouse approvals could eventually widen choice in established suburbs and transport corridors, but only where projects proceed to construction. A continued fall in detached-house approvals could limit new-house options, particularly in outer suburban estates and regional growth areas.

Sellers should not treat the figures as an immediate signal about prices. Approvals generally affect supply with a long delay, and local conditions will depend on the type, location and completion rate of projects nearby.

What it means for you

• Buyers may see more future apartment and townhouse choice, but approvals do not guarantee construction.
• New-house buyers should watch local land releases and builder activity, not just the national approvals total.
• Sellers face very different supply conditions by state, with NSW and Queensland strengthening while Victoria fell sharply.
• Investors should assess individual projects and suburbs because one large development can distort monthly approval figures.
