NSW Housing Code Compliance Check
Will your single-dwelling plans qualify for the 20-day CDC pathway, or are you committed to a DA? Clause-by-clause assessment against the Codes SEPP Housing Code.
Project home builders, owner-builders, building designers and certifiers running single-dwelling DAs through any NSW council.
What is the NSW Housing Code?
The Housing Code is Part 3 of the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 — the 'Codes SEPP'. It sets the state-wide standards a single-dwelling proposal must meet to qualify for a Complying Development Certificate (CDC) instead of a full Development Application (DA).
Where every standard is met, a private certifier (or council) can issue the CDC in 20 statutory days. That's vastly faster than the average DA, which currently sits at 115 days under the Statement of Expectations Order 2024 and is set to drop to 85 days by July 2027. The Housing Code is the most-used CDC code in NSW — most new single-storey and 2-storey dwellings on standard residential lots use this pathway.
The catch — the Code is unforgiving
The Housing Code is a tick-box rule. Every numerical standard must be met — a 100mm setback breach, a 0.05 FSR exceedance, a heritage listing on the next block — any of these can push the proposal out of CDC and into a DA. There's no merit-based variation under the CDC pathway.
Most of our customers find this out when their certifier tells them the proposal doesn't qualify, after the design is finished and the owner is committed. The Compliance Check at $49 catches the issues before the design is finalised — when changing a setback or wall height costs nothing.
Codes SEPP standards are state-wide. DCP standards are council-specific.
The Housing Code (Codes SEPP Part 3) is the same across NSW. Same setbacks, same FSR table, same articulation rules. That's what makes the CDC pathway possible. But if your proposal can't use CDC (heritage, BAL-FZ, flood-storage etc.), the DA pathway uses your council's DCP — and DCP numerical thresholds vary substantially by council.
Example: Warringah DCP 2011 (Northern Beaches) requires 40% landscaped area and a 6.5m front setback — both significantly tighter than the Codes SEPP defaults. Parramatta DCP 2023 has a different set of numbers again. Our compliance check assesses against the state-wide Codes SEPP AND flags the council DCP layer for DA-pathway review.
What the check covers
30 standards across 9 categories — every clause in the Codes SEPP Part 3 Housing Code, every BASIX commitment cross-check, every common DCP gotcha for the major metro councils.
- Lot eligibility — zone permissibility, lot size and frontage, heritage exclusions, environmentally sensitive land
- Building envelope and massing — Codes SEPP cl 3.8 (max 8.5m HOB), cl 3.9 (lot-size sliding GFA table — NOT a single FSR), cl 3.10 (setbacks and boundary planes)
- Setbacks — cl 3.10(1) (front setback = average of 2 nearest dwellings), side setbacks scaling with wall length, rear setback by lot size, battle-axe lot rules
- Built-form — cl 3.14 (articulation zone, materials, roof form, eaves)
- Privacy — cl 3.15 (privacy screens for windows on upper storey within 9m of neighbour)
- Solar access — 3 hours sunlight 9am-3pm to neighbours' POS
- Landscaped area — cl 3.13 (sliding scale by lot size)
- Stormwater and earthworks — Codes SEPP Pt 3 Div 5, cut/fill 1m maximum
- Hazards — bushfire (Pt 3 Div 2 + cl 1.19A, BAL-29 max for CDC), flood (Pt 3 Div 2), acid sulfate soils, contamination
- Parking — cl 3.16 (1 space < 600 sqm, 2 spaces ≥ 600 sqm)
- BASIX cross-check — every commitment visibly shown on plans
- NatHERS — current NCC 2022 minimum 7 stars, simulation method
Real fixture: Beacon Hill 2026
DA2026/0251 at 10 Gilles Crescent Beacon Hill (Northern Beaches Council, Warringah LEP 2011). Two-storey 4-bedroom dwelling by Clarendon Homes, $1.24M build cost. Submitted 12/03/2026, approved 07/04/2026 — 26 days end-to-end. The applicant ticked every Codes SEPP standard exactly: HOB 8.497m vs 8.5m maximum, side setbacks 0.9m, parking 2 spaces, 3hr-9-3 solar access, BASIX, ASS not applicable, flood not applicable. The Warringah DCP layer added tighter front setback (6.5m), rear setback (6m flat), and 40% landscaped area — all met. This is what a 'happy path' Housing Code DA looks like.
The statutory framework
The Housing Code is the most precisely-defined CDC code in NSW.
Codes SEPP 2008 Part 3 (Housing Code)
cl 3.1 (development that is complying development), cl 3.7-3.16 (built form, landscape, amenity, parking standards), cl 1.17A and 1.18 (general CDC requirements), cl 1.19 and 1.19A (excluded land)
Note: 3A.X cites refer to Part 3A (Rural Housing Code), NOT the urban Housing Code
Common confusion — many guides incorrectly cite '3A.X'. The urban Housing Code is Part 3 (cl 3.7-3.16). Part 3A is the Rural Housing Code, different standards entirely.
Sustainable Buildings SEPP 2022
BASIX certificate — must be valid (3 months from issue), commitments visibly shown on DA plans, cross-referenced to NatHERS where applicable
NCC 2022 Volume Two Specification 42
NatHERS thermal performance — minimum 7 stars under the current standard
Statement of Expectations Order 2024
Caps DA determination at 115 days from 1 Jul 2024, dropping to 85 days by 1 Jul 2027 — drives the CDC vs DA economic calculation
