In the 2024-25 financial year the ABS recorded 1,659 dwelling approvals across Baulkham Hills. Right now, 197 development applications are before the 2 councils covering the area. AreaSearch tracks 61 major projects here that are committed or under construction, the largest being Bella Vista and Kellyville TOD Accelerated Precincts at an estimated $8.00bn. On the ground, 3,766 new addresses have been verified since the 2021 Census — growth of 7.0% 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.

Approved Building Approvals in Baulkham Hills

What councils and certifiers have formally permitted — the ABS series, published about four months in arrears.

Approvals are running at 1.20 per 100 existing dwellings a year, well 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 82% of them. Detached houses make up 78% of the homes already standing here but only 18% of the past five years of approvals, so the area is densifying. The average approved dwelling is valued at $534,000 in construction cost.

Dwelling units approved each financial year. The dashed line is the five-year average of 1,659.

How intensively is it building?

Supply & Demand Is Baulkham Hills Building Enough Homes?

The same approvals, measured against the population they have to house.

Baulkham Hills approves about 10.2 new dwellings a year for every 1,000 residents. Since the 2021 Census it has added 8,239 residents and 3,766 new addresses — about 2.2 extra people per home built, below the 3.1-person average household, so building has run ahead of population growth. Housing the population projected for 2041 implies roughly 715 new dwellings a year from here, which puts the recent approval rate of 1,659 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 home 2.2
Average household size 3.1

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.

Approved (5-yr average) 1,659
Implied need to 2041 715

Implied need assumes the average household stays at today’s 3.1 people. Approvals are not completions, and not every approval is built.

ProposedLEADING · to August 2026 Development Applications in Baulkham Hills

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. 57 of them carry an AreaSearch analyst assessment — look for the Analysed marker in the search below.

AreaSearch tracks 1,295 development applications of material scale lodged with councils across Baulkham Hills, the most recent in August 2026. 197 of them are still in assessment. The biggest categories in the queue by value are commercial, multi-residential and aged care. Live applications account for about 302 proposed dwellings.

Estimated value of applications by development type. This is the clearest single picture of what kind of place Baulkham Hills is being asked to become. A further 76 applications sit across 2 smaller categories, too few to plot.

Beyond 2030: a further $21.3bn across 10 projects with completion dates further out — mostly precinct-scale programs whose dates are indicative. Kept out of the chart so the years you can act on stay readable.

Estimated value of tracked projects by the year they are due to complete, stacked by how certain they are. The dark band is money already being spent; the pale band is still an intention. Estimates are indicative and mix infrastructure cost with whole-of-precinct development value, so read the shape rather than the totals.

Baulkham Hills covers 12 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 Baulkham Hills.

Planning Authorities Councils Covering Baulkham Hills

Baulkham Hills spans 2 local government areas — The Hills Shire and Hornsby. 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 & Method Sources & Method for Baulkham Hills

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

Which council covers Baulkham Hills?

On development approvals, Baulkham Hills is adding new dwellings faster than New South Wales as a whole — 1.20 approvals per 100 existing dwellings a year against the state figure of 0.59.

How current is this development data?

ABS building approvals are published with a lag of roughly four months; this page carries the series to June 2026. Development applications are collected from council planning portals and refresh continuously, with the most recent application here lodged in August 2026. Major project records are reviewed on an ongoing basis. Each section carries its own currency label so the four are never confused.

Development data is provided for general information. Estimated values, dwelling counts and delivery dates come from the lodging or delivering party and are not independently verified by AreaSearch. Confirm anything material with the relevant council or agency before relying on it.
