Housing Code (NSW)

The NSW Housing Code sits inside the Codes SEPP 2008 and sets CDC eligibility rules for residential builds. Overlays (acid sulfate, flood, bushfire) gate it.

The Housing Code (formally the General Housing Code in the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (NSW)) is the section of the Codes SEPP that sets the eligibility and development standards for Complying Development Certificates (CDC) on residential builds in NSW. It is the fast-track DA-bypass pathway for single dwellings, secondary dwellings, alterations, and minor additions that meet the prescriptive standards.

Where it sits. The Codes SEPP is the umbrella; the General Housing Code is one of several codes within it (others include the Inland Code, Greenfield Housing Code, General Development Code). The Housing Code applies broadly across NSW’s residential zones.

What the Housing Code prescribes:

  • Minimum lot size and frontage for CDC eligibility (varies by zone and building type).
  • Maximum building height (typically 8.5 m for a single dwelling).
  • Maximum site coverage and floor space ratio.
  • Setbacks from front, side, and rear boundaries.
  • Privacy (window-to-window distances, balcony privacy screens).
  • Solar access for adjoining properties.
  • Tree retention (significant tree protection within the building envelope).
  • Stormwater management (typical site-level requirements).

A build that meets every standard is eligible for CDC. A build that fails any standard goes through the DA path via council.

The “knock-out” overlays. Even when the build itself meets every Housing Code standard, the lot’s overlay status can rule out CDC:

  • Heritage items or HCAs.
  • Bushfire-prone land above defined BAL thresholds (typically BAL-29+).
  • Flood-prone land in mapped categories.
  • Acid sulfate soils in specific classes.
  • Coastal hazard areas.
  • Contaminated land flagged on the Section 10.7.
  • Critical habitat mapped for endangered species.
  • Aircraft noise zones.

The Section 10.7 planning certificate is the primary disclosure document for these overlays.

The CDC vs DA decision tree for NSW residential:

  1. Read the Section 10.7 for overlay status. If any “knock-out” overlay applies, CDC is unavailable; proceed to DA.
  2. Compare the build to every Housing Code standard. If any standard fails, proceed to DA.
  3. Confirm the certifier is willing to issue CDC on the proposed build. Private certifiers can decline jobs with marginal compliance.
  4. Lodge CDC with the certifier. Determination typically 10-20 business days.
  5. If CDC declined or not pursued, lodge DA with council. Determination typically 60-120 days for residential.

For builders.

  1. Check overlay status first, before pricing or designing. Discovering a heritage item on the lot after design lock-in is the most common cause of rebuilds at concept stage.
  2. Spec to the Housing Code standards from the start. Designing slightly over a standard (e.g. 8.8 m height when the code allows 8.5 m) costs the CDC pathway for trivial benefit.
  3. The CDC is faster and cheaper than the DA path. Industry-typical figures: CDC $1,500 to $3,500 in fees; DA $3,000 to $10,000+ in fees. Time difference is even larger (10-20 days vs 60-120+ days).
