Estate Homes Growing Up in Mount Annan
From dairy farm to suburb
Dairying on this land ended in 1978. Housing estates followed from the late 1980s and grew strongly in the 1990s. In 2021, 11,784 people were counted across the suburb. They lived in 3,722 private homes. Around 96% were stand-alone houses, and the count found no flats. Close to three in four homes (73.7%) had at least four bedrooms.
Two councils
The residential streets are in Camden Council. A smaller area, mostly the Australian Botanic Garden, belongs to Campbelltown City Council. The garden opened in 1988 and covers 419 hectares. The exact address settles which council's plan is used. Everything on this page relates to Camden land.
Zones and lot sizes
Camden's 2010 local plan zones most streets R2, for low density homes. Sampled lots there carry a minimum of 450 square metres. In some pockets the zoning is R3, for medium density housing, and the minimum falls to 250 square metres. Two streets side by side can differ. The Upper Canal, a State heritage item, also runs through the area.
Typical work
Common projects and how they get approved
What owners build here
Big family homes from the 1990s produce a familiar list of jobs.
- Pools, decks and patio roofs. These are usually fitted into a back yard shaped by the original estate plan.
- Sheds, garages and carports. Curved or tapering lots make setbacks the main question.
- Granny flats. Possible on many blocks with enough area and width.
- Rear or upstairs additions. Popular with growing families.
Knockdown rebuilds are less common, as most houses here are fairly young.
How approval usually works
A small patio or pergola can be exempt if it stays inside every limit for size, height and setback. Plenty of estate lots are too cramped for that. Larger jobs often suit a CDC, a fast approval a certifier can issue. Otherwise you need a DA to Camden Council and then a CC.
Two issues come up often. First, a lot size printed on council's map does not, alone, permit a subdivision or a second dwelling. The zone, Camden's DCP and any title restriction all count. Second, older homes often carry unapproved pergolas or enclosed carports. Unapproved work cannot be relied on by a certifier, so you may need to regularise it first through a building information certificate. Bushfire mapping, drainage easements and vegetation near the botanic garden edge can also limit siting. Send your planning certificate, survey and past approvals early. CertifiBuild will review the history of your site before design work starts.

Local questions
Questions we hear about this suburb.
No two lots in Mount Annan are the same. Give us your address and we will check every map that affects it.
See the council pageMy Mount Annan pergola was never approved. Will that hold up a new pool?
It can. Work that never got approval cannot be relied on by any certifier, so an old pergola or enclosed carport near the new pool may hold up a complying development certificate (CDC) or construction certificate. Many Mount Annan homes are now a few decades old and have picked up additions along the way. Search council’s records for past approvals before the pool is designed. If something was never approved, a building information certificate from Camden Council can bring it into line. Send your planning certificate, survey and any approvals early so the site history is clear.
Does an R3 zoning let me build a duplex in Mount Annan?
No, the zone alone is not enough. A few Mount Annan pockets carry R3 zoning, where the mapped minimum drops to 250 square metres, against 450 on most R2 streets. Even so, that smaller figure is no green light for a second home. Whether a dual occupancy works depends on the uses Camden’s 2010 local plan permits in your zone, your block’s width at the street and its area, the council’s development control plan, and any covenant the original estate placed on your title. Adjoining streets can differ, so check your own block before briefing a designer.
Is a small Mount Annan patio exempt from approval?
It may be, if it stays within every size, height and setback limit for exempt development. Many Mount Annan estate lots are narrow, curved or tapering, so a patio often ends up too close to a boundary to qualify. A roofed structure near the boundary usually needs formal approval: a complying development certificate (CDC) where the codes fit, or else a council development application (DA) with a construction certificate to follow. Check easements and drainage lines on your survey too, since building over them can need extra approval.
