About Western Sydney

Western Sydney encompasses some of the largest local government areas in metropolitan Sydney, including City of Parramatta, Blacktown City Council, Penrith City Council, Liverpool City Council, Canterbury-Bankstown Council, Cumberland City Council, and Fairfield City Council. The region is experiencing a prolonged construction boom driven by population growth, the Western Sydney Airport at Badgerys Creek, and major transport infrastructure including the Sydney Metro West. New housing estates, townhouse developments, and dual-occupancy builds dominate the residential sector, while Parramatta's CBD is being transformed by a wave of commercial and residential towers. Flood-affected land is a significant planning consideration, particularly along the Hawkesbury-Nepean, Georges River, and Parramatta River corridors.

FAQ

Frequently Asked Questions

How does flood planning affect building certification in Western Sydney?
Flood planning is a major consideration across Western Sydney, with many properties located within flood planning areas along the Hawkesbury-Nepean River system, the Georges River, and Parramatta River and its tributaries. If your property is flood-affected, additional documentation is required for certification, including flood studies, minimum floor-level calculations, and compliance with flood-related development controls in the relevant council's LEP and DCP. Some flood-affected properties may be excluded from the CDC pathway. Sydney Wide Certifiers can assess your site's flood status and advise on the documentation required.
Can I get a CDC for a dual occupancy in Western Sydney?
Dual occupancies (both attached and detached) can often be approved via a Complying Development Certificate in Western Sydney, subject to meeting the standards in the State Environmental Planning Policy (Exempt and Complying Development Codes). Key requirements include minimum lot size (typically 400 to 500 square metres depending on the zone and council), maximum building height, setbacks, landscaping, car parking, and private open space provisions. Not all lots qualify — properties on flood-prone land, in heritage areas, or on battle-axe blocks may be excluded. We assess your site's eligibility as the first step in the process.
What is the typical turnaround for a CDC on a new home in Western Sydney?
For a straightforward new dwelling on a standard residential lot, we typically issue a Complying Development Certificate within 10 business days of receiving a complete application. For volume builders with standardised house designs, turnaround can be even faster as many documentation elements are already in place. The key to a fast approval is submitting a complete application from the outset — including architectural plans, structural engineering, BASIX certificate, soil classification report, and any required specialist reports. We provide a checklist at engagement to help ensure nothing is missed.
