Ku-ring-gai Council
Private building certifier in Roseville
Roseville homes often sit in a heritage conservation area, near a station precinct, or both. Before you plan an addition, pool or granny flat, we help you establish which rules apply to your lot today.

Heritage streets and station rules in Roseville
Mostly houses, at Ku-ring-gai's southern end
Roseville is the last Ku-ring-gai suburb on the rail line heading south. Roseville's 2021 population of 10,340 was spread over 3,792 private dwellings. Houses on separate lots were 68.8% of occupied homes, apartments 28.5%. Ku-ring-gai covers most of Roseville, while one portion belongs to Willoughby City Council. Your address decides which council's plan applies. For the Ku-ring-gai section, the plan is the Ku-ring-gai Local Environmental Plan 2015.
Conservation areas
Council maps heritage conservation areas in Roseville and across its border with Lindfield. These became law in July 2013. It started in 1992, when a National Trust survey across the state flagged possible areas. Consultants reviewed them from 2001 to 2010. The area inventories have since been refreshed by council with history, maps and photos taken in 2024. A house does not need its own listing to be inside one.
The TOD story so far
Ku-ring-gai has four precincts under the state's transport oriented housing program, and Roseville station is one. The State's controls started in May 2024. New applications under them closed on 13 June 2025. Next came council's TOD Alternative, gazetted in mid November 2025 with revised height maps and floor space maps. On 18 November 2025 council resolved to drop its court challenge.
Typical work
Common projects and how they get approved
What owners build here
Most house work in Roseville includes the following, often in older homes with established gardens:
- Additions at the back or on a new upper level. Inside a heritage area, what the street sees is closely scrutinised.
- Kitchen and bathroom renovations. Usually simple unless structure or the facade changes.
- Garages, carports and front fences. Front fences and gardens form part of heritage character.
- Decks, pools and granny flats. Lot size and tree cover need checking first.
Apartment work is Class 2 and needs a different certifier. A dual occupancy cannot go on a heritage item, a TOD site or bushfire prone land.
How approval usually works
A CDC, which a certifier can issue when a project meets every code standard, is often possible for rear additions. Heritage listing, bushfire mapping or the precinct can close that path. Heritage items are also outside the State's low and mid-rise rules. A dual occupancy CDC needs 1,015 square metres or more. If the standards cannot be satisfied, you lodge a DA with council and get a construction certificate afterwards. Designs drawn under older precinct rules should be checked again against current maps. For a lot on the Willoughby side, that council's rules govern. Send your planning certificate and survey first. CertifiBuild then works through the heritage and precinct questions with you, step by step.

Local questions
Questions we hear about this suburb.
No two lots in Roseville are the same. Give us your address and we will check every map that affects it.
See the council pageIs a rear extension allowed on a Roseville heritage area home?
Usually, yes. Sitting in a Roseville conservation area changes how your extension is assessed rather than ruling it out. Council looks at the whole streetscape, so front fences, gardens, trees and anything visible from the street carry weight, while a well-placed rear addition often draws less scrutiny. These areas became law in mid 2013, and council has refreshed the notes for each one with new photos. Check whether your house is also a heritage item in its own right, since that closes some code pathways. A planning certificate will show both.
What happened to the station precinct rules in Roseville?
They have changed twice. State transport oriented development (TOD) rules covered land near Roseville station from May 2024, and fresh applications under them stopped being accepted from 13 June 2025. After that, council’s own TOD Alternative took effect in mid November 2025 with fresh maps for building height and floor space, and council later voted to end its court case. Applications lodged before the June cut-off kept the earlier rules. Plans drawn up under an older version should be rechecked against today’s mapping for your lot.
What will a private certifier do on my Roseville job?
We check your plans against the rules that apply and, when they are met, issue either the complying development certificate (CDC) or the construction certificate that follows a council development application. You appoint us as principal certifier, and we carry out the critical stage inspections, such as footings and framing, as the build progresses. When the build is done and complies, we issue the occupation certificate. For Roseville homes we also flag heritage, bushfire and precinct issues early. Our scope covers Class 1 houses and Class 10 structures only.
