In the 2024-25 financial year the ABS recorded 630 dwelling approvals across Marrickville - Sydenham - Petersham. Right now, 126 development applications are before the 2 councils covering the area. AreaSearch tracks 20 major projects here that are committed or under construction, the largest being M6 Stage 1 at an estimated $3.10bn. On the ground, 1,219 new addresses have been verified since the 2021 Census — growth of 4.9% on the existing address base.
These four figures are deliberately not added together. An application, an
approval and a project under construction are often the same building at three points in its life,
measured by three different bodies with three different lags. Read them as a sequence, not a total.
ApprovedBuilding Approvals in Marrickville - Sydenham - Petersham
What councils and certifiers have formally
permitted — the ABS series, published about four months in arrears.
Approvals are running at 0.79 per 100 existing dwellings a year, above the New South Wales rate of 0.59. Recent approvals are dominated by attached housing — apartments, townhouses and other non-detached dwellings make up 94% of them. Detached houses make up 29% of the homes already standing here but only 8% of the past five years of approvals, so the area is densifying. The average approved dwelling is valued at $620,000 in construction cost.
For its size, Marrickville - Sydenham - Petersham is adding 0.79 dwellings a year per 100 existing homes — above the New South Wales rate of 0.59 and the national rate of 0.71. That is about 5.4 approvals a year for every 1,000 residents. Building intensity has fallen by about 34% across the published series.
Measured against people rather than housing stock, Marrickville - Sydenham - Petersham is approving 4.96 dwellings a year per 1,000 residents — in line with the New South Wales rate of 5.61. The two rate views differ by household size, which here averages 2.5 people per home. Housing the projection to 2041 would need about 2.03 per 1,000 residents a year.
Dwelling approvals a year per 100 existing
homes, with New South Wales and Australia for comparison. This is the
same activity as the totals view, divided by the size of the area — which is the only
fair way to compare a large SA3 with a small one.
Dwelling approvals a year per 1,000
residents, each year divided by that year’s estimated resident
population (ABS ERP at 30 June), not by today’s — which matters most in fast-growing
areas, where a fixed denominator can understate the early years by half. The most recent periods use the latest published ERP, as the population series runs a year behind approvals. Read it alongside the per-100-homes view: the two differ wherever household size does.
Dwelling units approved each financial year. The dashed line is the five-year average of 313.

What is here, and what is coming
Detached houses as a share of existing homes,
against the share of recent approvals.
The same approvals, measured against the population
they have to house.
Marrickville - Sydenham - Petersham approves about 5.4 new dwellings a year for every 1,000 residents. Since the 2021 Census it has added 3,356 residents and 1,219 new addresses, roughly one new home per 2.8 extra residents — broadly in step with an average household of 2.5. Housing the population projected for 2041 implies roughly 118 new dwellings a year from here, which puts the recent approval rate of 313 a year comfortably ahead of what the projection needs.
Growth against supply since the Census
People added for every new address verified,
against the size of an average local household.
People added per new home2.8
Average household size2.5
A bar longer than the household average means
the area gained more residents than its new housing could hold, and the extra had to be
absorbed by existing homes.
Approval rate against projected need
Dwellings a year: what is currently being
approved, against what the 2041 population projection implies.

Implied need assumes the average household stays

completions, and not every approval is built.
ProposedLEADING · to July 2026Development Applications in Marrickville - Sydenham - Petersham
What is being asked for right now — applications
collected from council planning portals, before any of it reaches the ABS series above.
AreaSearch tracks applications of material scale; routine minor works such as signage and
fencing changes are not carried, so these are not counts of every application lodged. 23
of them carry an AreaSearch analyst assessment — look for the
Analysed marker in the search below.
AreaSearch tracks 931 development applications of material scale lodged with councils across Marrickville - Sydenham - Petersham, the most recent in July 2026. 126 of them are still in assessment. The biggest categories in the queue by value are industrial, mixed-use and commercial. Live applications account for about 85 proposed dwellings.

DistributionWhere Development Is Happening in Marrickville - Sydenham - Petersham
Marrickville - Sydenham - Petersham covers 4 statistical areas. Follow any of them through for a full profile of population, housing, sales and amenity at local scale.
Map builder
Each area below opens a map builder on its own page — a tool for
putting a map and a table into a report. Pick the place types you want plotted
(schools, supermarkets, medical, child care, transport and the rest of what
AreaSearch holds), add development applications as their own layer, drop your own
points, then recolour, renumber and export the result as a table or CSV.
A this area only toggle clips everything to the boundary you are looking at.
Searches are charged against your credit balance — 1 credit per 40
results from AreaSearch data — and setting filters costs nothing until
you search. The builder works on one suburb-sized area at a time, which is why it
opens per area rather than across the whole of
Marrickville - Sydenham - Petersham.
Marrickville - Sydenham - Petersham spans 2 local government areas — Inner West and Sydney. Applications here are assessed by whichever of those councils the site falls within. AreaSearch publishes development
figures at ABS statistical boundaries rather than council boundaries. That is deliberate: the ABS
issues a separate official building-approvals series for local government areas, and totals
built up from statistical areas would not match it. Reporting at SA3 keeps every figure on this page
reconcilable with the published ABS series.

Data & MethodSources & Method for Marrickville - Sydenham - Petersham
The four tenses, and what each one can tell you
Proposed — development applications
Collected from council planning portals. The
earliest signal available, but the least certain: many applications are amended,
withdrawn or refused, values are the applicant’s own estimate, and coverage
varies by council. This is a curated set, not the full council feed:
AreaSearch carries applications of material scale and does not track routine minor
works such as signage, fencing or small alterations, so the counts here are lower
than a council’s own total lodgement figure and should not be compared with it. Applications still shown as under assessment more than
18 months after lodgement are reported separately
and kept out of the live-queue figures: the age profile of open applications is
sharply split between a genuine queue under a year old and a long tail of records
councils never closed. Not every state publishes a cost of works — Queensland,
the Northern Territory and the ACT publish none at all — so on those pages
applications are counted rather than valued and no dollar figure is shown
rather than a partial one. Treated here as a snapshot of the current queue only —
AreaSearch does not chart application counts over time, because the history
reflects when each portal was collected rather than when development happened.
Approved — ABS building approvals
The official series, aggregated to SA3 from
ABS building approvals data, currently published to June 2026.
Counts dwelling units approved, not buildings and not completions. The most recent
financial year is annualised from nine months of data wherever it appears and is
labelled as such.
Building — major projects
Projects tracked individually by AreaSearch
from Infrastructure Australia, state infrastructure agencies, developer disclosures
and council records. Values are estimates and delivery dates are targets. Ranked on
this page by committed value and delivery stage rather than by distance.
Delivered — verified new addresses
New residential addresses verified in the national
address register since the 2021 Census. This is the closest available measure of what has
actually been built, though address creation can lead occupation and lags
construction. It is not a completions count.
Boundaries
