JJ Drafting & Design: Expert Q&A for Sydney Homeowners (2026)

Q: What is the fastest way to get my Sydney building project approved?

A: For eligible residential projects like granny flats or minor renovations, a Complying Development Certificate (CDC) is the fastest route, bypassing Council and using a Private Certifier. If your project is more complex, such as a large Dual Occupancy, we manage the full Development Application (DA) process with your local Council. Sydney Building Approval FAQ

Q: Can I build a duplex on my R2-zoned property in 2026?

A: Under the latest NSW housing reforms, many R2 low-density zones now allow for Dual Occupancy (duplexes). Eligibility depends on your specific lot size (often 450sqm+) and frontage (usually 12m–15m). We audit your property’s Section 10.7 certificate to confirm your exact development rights.

Q: How do I legalise existing building works that don’t have approval?

A: If you’ve received a Show Cause Notice or built without a permit, you must apply for a Building Information Certificate (BIC). We provide the required “as-built” architectural plans and coordinate with engineers to prove to the Council that the structure meets the National Construction Code (NCC).

Q: What are the new 2026 BASIX requirements for renovations?

A: Most Sydney renovations over $50,000 now require a BASIX Certificate that meets a 7-star NatHERS thermal rating. This involves high-performance glazing, optimized insulation, and smart solar orientation to reduce energy consumption.

Q: Can I build a granny flat on a block smaller than 450sqm?

A: While 450sqm is the standard for CDC approval, some local councils allow secondary dwellings on smaller lots via a DA. We specialize in maximizing small lots (200sqm–450sqm) to ensure you still achieve high rental yields and privacy.
