About Inner West

The Inner West is primarily governed by Inner West Council (formed from the former Ashfield, Leichhardt, and Marrickville councils), with parts of the area falling under Burwood Council and Strathfield Council. The region is characterised by dense, established housing stock — terrace houses, semi-detached dwellings, and California bungalows on relatively compact lots. Rear additions, ground-floor extensions, granny flat (secondary dwelling) construction, and attic conversions are extremely popular project types. Many properties sit within heritage conservation areas, particularly in Haberfield (a nationally recognised garden suburb), Annandale, and Balmain. Granny flat development is a major growth area, driven by strong rental demand and the relatively generous provisions under the Affordable Rental Housing SEPP.

Our Services in Inner West

Sydney Wide Certifiers helps Inner West property owners secure Complying Development Certificates for granny flats, rear additions, and new dwellings where the CDC pathway applies. We also issue Construction Certificates for DA-approved projects and carry out all mandatory inspections through to the Occupation Certificate. Our familiarity with Inner West Council's DCP — including its detailed controls on terrace house alterations, setbacks on narrow lots, and heritage-area provisions — means we can identify potential compliance issues early and help you resolve them before they cause delays.

FAQ

Frequently Asked Questions

Can I build a granny flat on my Inner West property using a CDC?
In many cases, yes. Secondary dwellings (granny flats) up to 60 square metres can be approved via a Complying Development Certificate under the State Environmental Planning Policy (Affordable Rental Housing), provided your lot meets the minimum size requirement of 450 square metres and the proposed design satisfies all relevant standards including setbacks, height, car parking, and landscaping. However, properties within heritage conservation areas — which are common in suburbs like Haberfield, Annandale, and Balmain — are generally excluded from the CDC pathway and require a DA. Sydney Wide Certifiers can assess your property and advise on the best approval route.
What are the common certification challenges for Inner West terrace house renovations?
Terrace house renovations in the Inner West often involve navigating heritage conservation area controls, party wall considerations with adjoining properties, tight site access for construction, and compliance with Building Code of Australia requirements for natural light, ventilation, and fire separation in narrow building envelopes. Our certifiers understand these challenges well and can review your plans early to flag any issues. We also advise on waterproofing requirements for below-ground-level rooms, which are increasingly common in terrace rear extensions.
How quickly can I get an Occupation Certificate for my Inner West project?
An Occupation Certificate is issued once all mandatory critical-stage inspections have been satisfactorily completed and the building work is confirmed as compliant with the approved plans and the Building Code of Australia. Provided there are no outstanding non-compliances, we aim to issue the Occupation Certificate within a few business days of the successful final inspection. We recommend booking your final inspection as early as possible once works are nearing completion to avoid any gap between finishing trades and receiving your OC.
