As part of the same wave of planning reform, the NSW Government is developing a new policy that would draw together all the state’s climate and natural hazard rules, flooding, bushfire risk, coastal change, and extreme heat into one unified planning instrument. It’s out for public comment at the moment and not yet in force, but the intent is clear, and the direction is worth understanding before your next project.

Why this policy exists

Right now, how your property’s climate risk is assessed in a development application depends heavily on which council you’re in. Flood levels are set locally. Coastal rules vary up and down the coast. Bushfire requirements reference state provisions but interact with local controls in ways that aren’t always consistent. The proposed policy aims to fix that by creating a single statewide standard that applies everywhere. The intent is not to add new layers of complexity. It’s to make risk assessment more predictable so that a well-prepared application in one LGA is held to the same baseline standard as one in another.

Who it will actually affect

For most homeowners in established inner-city and suburban Sydney, this will have little effect on a standard renovation or new build. The implications are most direct for:

• Coastal and waterfront properties. Setback and floor level requirements for homes near the foreshore may tighten as a consistent statewide benchmark replaces locally variable rules.
• Sites near creeks, drains, or low-lying areas. Flood risk overlays may shift in some council areas. If you’re buying or developing near any mapped waterway, understanding the current flood controls and how they might change is important.
• Properties adjacent to bushland. Existing bushfire requirements are likely to be absorbed and in some instances updated, particularly around asset protection zones and construction standards.
• Large residential projects in Western Sydney growth areas. Extreme heat design requirements may become part of the approval framework in high-heat zones, affecting material choice, shading, and landscaping.

If your property sits well clear of water, bushland, and known flood areas, this policy is unlikely to change anything material for you. If it doesn’t, now is the moment to get across the current rules before they evolve.

What to do before the policy is finalised

The draft is open for public comment right now, and submissions close within weeks. If you own or are planning to develop a property in any of the categories above, reading the draft and understanding what it means for your specific site is worthwhile. More broadly, this is a good reminder that the most valuable time to understand a site’s planning position is at the very beginning of a project not mid-design.
