Sloping sites and leafy streets in Roseville Chase
Ku-ring-gai's smallest locality
Roseville Chase had 1,618 residents and just 546 private dwellings at the 2021 Census. No locality in Ku-ring-gai has a smaller dwelling count. Detached houses took around 96.5% of occupied homes, semis and townhouses 3.5%, and flats 0.8%. To protect privacy, small figures are nudged slightly by the ABS. In a suburb this size, the published shares can add to a bit over 100%.
Planning instruments
The governing plan is the Ku-ring-gai Local Environmental Plan 2015. In June 2021 it took in two older instruments, the shire's Planning Scheme Ordinance and the LEP for local centres. Council maps no heritage conservation area in Roseville Chase. The nearest ones sit along the railway at Roseville and Lindfield. An individual house here may still be heritage listed in its own right.
Trees and bushfire
Council has published advice on cutting back or removing trees on private land. It also explains the clearing code run by the Rural Fire Service. Council links its lot size rules to deep soil, canopy cover and the endangered forests still found in the shire. Big established trees and their roots often fix where a structure can go. Plot them on the survey before you settle the building outline, since shifting a design later wastes time.
Typical work
Common projects and how they get approved
What owners build here
Almost all work here involves a house and its land. Typical projects include:
- Decks and pools. On a falling site, excavation, retaining and drainage need resolving early. Pools also need a compliant barrier.
- Additions at the rear or upstairs. Footings and stormwater shape what is buildable at a sensible cost.
- Garages, carports and replacement homes. Driveway levels can be tricky on steep lots.
- Granny flats. These suit larger holdings with enough usable land left over.
How approval usually works
A CDC, the quicker approval a certifier can grant, is available only if each code standard is satisfied. Being heritage listed, or mapped for bushfire, may narrow that option. Bushfire prone land also rules out dual occupancy in the R2 zone. Council-wide, a dual occupancy CDC requires land of 1,015 square metres or more. If not, you lodge a DA for council to decide, then obtain a construction certificate. On a falling block, any new deck, pool or rear extension means digging, retaining, stormwater and structure must be designed in from day one. Leaving those site issues until later is a common reason simple projects stall. Send the address, title, any past approvals and a contour survey first. CertifiBuild then weighs site conditions and planning rules together, before any design is committed to.

Local questions

No two lots in Roseville Chase are the same. Give us your address and we will check every map that affects it.
See the council pageIs a deck or pool possible on a steep Roseville Chase block?
Usually, yes, provided digging, retaining walls, drainage and structure are planned in from day one. On a Roseville Chase block that falls away, the finished levels next to the house and along the boundary often decide what is acceptable, so a detailed contour survey is the key document. Any pool must have a compliant safety fence, which can be harder to fit on terraced ground. Show big trees and their roots on the survey as well, since they often limit where footings can go.
Is Roseville Chase in the Roseville heritage area?
No. Council maps no heritage conservation area in Roseville Chase. The closest ones run along the railway line to the west, around Roseville and Lindfield. That said, a single house can still be listed as a heritage item in its own right under the Ku-ring-gai Local Environmental Plan 2015, and a listing narrows the code-based approval options. Order a planning certificate for your address to see its heritage status, and look at bushfire mapping too, because it can also affect your pathway.
Why do the Roseville Chase census figures exceed 100%?
The ABS nudges small counts slightly to protect people’s privacy. In a locality as small as Roseville Chase, with 546 private dwellings in 2021, those tweaks show up more clearly, so the dwelling type shares can total a little over 100%. The broad picture is still reliable: detached houses made up about 96.5% of occupied homes. Read them as a rough guide to local housing, not a tally of buildings. For your own project, the survey and planning certificate matter far more than census data.
