Private building certifier in Petersham
Every Petersham project starts from two facts: where you sit relative to the railway and which heritage group you belong to. CertifiBuild certifies rear additions, upper floors, renovations and Class 10 work across both halves of the suburb.

Local rules
Petersham's water tower ridge and the streets either side
Two precincts and a shopping strip
The Marrickville DCP 2011 (council's detailed design rules) splits Petersham into North and South precincts, with its commercial centre handled in a separate chapter. The railway divides the suburb. In the north, regular streets give way to less regular blocks around big parks and school sites. That area holds several separate heritage groups with their own character. No one northern style exists to copy.
The southern ridge
South of the line, the land climbs to a ridge near the water tower, then falls away in several directions. Heritage groups include Morgan Street and the Norwood Estate. The shopping strip is left out of the residential precinct, so check which map your lot is on even if you live close to the shops.
Masterplan sites
The southern chapter also contains several masterplan areas for particular sites. Those envelopes stay with the mapped sites and do not pass to the house next door. Close to half of all homes are flats. Houses, semis and terraces account for the rest.
Typical work
Common projects and how they get approved
What owners build here
Older houses in the established heritage groups shape most of the residential work here. Common Petersham jobs include:
- Rear additions to period homes, drawn against the lower neighbours on sloping lots.
- Upstairs additions, checked in section drawings before anyone fixes the design.
- Internal renovations of semis and terraces, where shared structure and services need checking.
- Roof and external detail repairs that respect the original fabric.
- Garages and carports on lots with workable access and space.
Shop fit-outs, rooms over shops and apartment work fall outside Class 1 and 10, so they need a different certifier. Large backyard buildings are uncommon here.
How approval usually works
To decide between a CDC (a streamlined approval set by State rules) and a DA (approval from council), first confirm the lot's current LEP, any State provisions, its DCP precinct and its heritage status. On the southern ridge, draw sections through your site and the neighbours' ground levels. An addition at the back may seem small from the front yet show a tall wall to the neighbours behind. Working this out early lets privacy, sunlight and retaining be dealt with before levels are set on site. Once approved, the construction certificate has to follow the consented form. Do not treat a masterplan site or a shop building as a guide for what a house can do. CertifiBuild helps Petersham owners pin down the right precinct and heritage group early and responds promptly once building is under way.

Local questions
Questions we hear about this suburb.
No two lots in Petersham are the same. Give us your address and we will check every map that affects it.
See the council pageIs a second storey possible on my Petersham house?
Possibly. It depends on your precinct, how your house contributes to its heritage group and its impact on the homes beside you. The Marrickville development control plan splits Petersham into North and South precincts at the railway. On the southern ridge near the water tower, the land drops away, so new rooms at the back can look much taller from below. Get measured levels and cross sections early, so privacy, sun and retaining walls can be sorted out before you commit.
Does the shopping strip chapter cover my house nearby?
No. The Marrickville development control plan deals with the shopping strip in a different chapter from the residential precincts. Find your property on the right map, even if you live a few doors from the shops. Homes outside the strip follow residential guidance, so a row of shops gives no guide to the size or form of your addition. Confirm your lot’s heritage group as well, since several distinct groups exist across Petersham.
Can a nearby masterplan site justify a bigger addition?
No. South of the railway, a handful of named sites have masterplans, and their envelopes stay with those mapped sites. They do not pass to the house next door. An ordinary Petersham lot is judged on its own planning controls, heritage setting and impact on neighbours, whatever is being built nearby. Confirm the zoning, precinct and heritage status of your land, then plan the addition to suit your own site.
