Auckland suburbs / Farm Cove
What can you build on your Farm Cove section?
Zoning, flood flags and 70m² granny-flat potential for any Farm Cove address — free, in about 30 seconds, straight from Auckland Council data.
Farm Cove, in the Howick Local Board area, is covered by the same 2026 rule changes reshaping the whole city: the old blanket intensification rules were withdrawn, Plan Change 120 won’t settle until around mid-2027, and in the meantime what you can do with a section depends on its exact zoning and overlays — not the suburb’s reputation.
The one change almost everyone in Farm Cove should know about: since 15 January 2026, a single-storey standalone dwelling up to 70m² — a granny flat — can be built without a building consent on many residential sections (a PIM and licensed building practitioner are still required). Whether yours qualifies comes down to your zone, your site, and any hazard flags — which is exactly what the checker reads.
And because hazard-exposed land is now being directed toward less development capacity, a flood or overland-flow overlay matters more than it used to. Better to know in 30 seconds than at consent time.

This is the map, not your section. A suburb is a patchwork — Mixed Housing Suburban is the most common zone in Farm Cove, but neighbouring properties can sit in different zones, and overlays (special character, flooding, heritage) change what applies regardless of zone. The only figure that matters for your project is your own parcel’s — the checker above reads it in about 30 seconds.
Farm Cove questions, straight answers
- Can I build a granny flat in Farm Cove?
- It depends on your exact section, not the suburb. Since 15 January 2026 a single-storey standalone dwelling up to 70m² can be built without a building consent — but your zone, site size, setbacks and any hazard overlays decide whether it works on your land. Our free checker reads your parcel's council data in about 30 seconds.
- What are the planning rules in Farm Cove right now?
- Auckland's rulebook is mid-change: the old blanket intensification rules were withdrawn in late 2025 and Plan Change 120 isn't expected to be fully operative until around mid-2027. Density is being directed toward frequent transit, and reduced on hazard-exposed land — so what applies to a specific Farm Cove property genuinely varies parcel by parcel. On the current zoning map, 89.1% of Farm Cove's zoned land is Mixed Housing Suburban, 8.5% of Farm Cove's zoned land is Open Space: Informal Recreation, 1.2% of Farm Cove's zoned land is Open Space: Sport and Active Recreation; residential zones make up about 89% of the suburb in total. That is the map, not a rule about your section.
- Do flood overlays affect what I can build in Farm Cove?
- They can. Under the 2026 legislation, flood- and hazard-exposed land is being directed toward less development capacity — so an overland flow path or flood plain flag on your section can affect what you're allowed to build, not just insurance. The checker shows your parcel's hazard flags from council data.
