What the control sets
One figure in square metres or hectares, mapped per parcel, applying to lots created by a subdivision that requires consent. It is a development standard, so it sits in the same family as height and floor space ratio and is varied the same way.
The clause as made varies more between LEPs than clauses 4.3 and 4.4 do. Many councils add companion clauses — a 4.1A, 4.1AA or 4.1B — dealing with particular cases such as subdivision for dual occupancies, subdivision in rural zones, or lots created for public purposes. Read the numbered clauses around 4.1 in the applicable LEP, not just 4.1 itself.
Why it also controls dwellings, not just lots
Two mechanisms connect a subdivision standard to dwelling yield.
The first is the Land Use Table and the clauses around it. Many LEPs permit dual occupancy, multi dwelling housing or attached dwellings in a zone only where the lot meets a stated area — sometimes the Lot Size Map figure, sometimes a separate number in the clause. On those sites the mapped minimum is the gate on housing type, before any question of subdividing arises.
The second is the complying development pathway. The Housing Code’s standards start at 200 m² and step with lot area from there, so the area of the lot decides how much house the code will approve on it — a point the section below makes concrete.
The low- and mid-rise housing reforms have made dual occupancies permissible with consent in R2 zones across much of the state, and set their own standards for that housing, along with uplift near town centres and stations. Those entitlements come from a State Environmental Planning Policy rather than from the council’s LEP, and where the two are inconsistent the SEPP generally prevails — so a permissibility answer read only from the LEP can be out of date. Check the SEPP’s own standards and exclusions for the specific land before relying on either.
What the clause does not reach
Clause 4.1 bites on the lots a subdivision creates. It is generally directed at the creation of new torrens lots rather than at the strata subdivision of a building already approved on a single lot, and it does not apply to subdivision under the Community Land Development Act 1989 either — which is why a dual occupancy can often be strata-titled on a site that could not be torrens-subdivided into two. The clause as made in a particular LEP is what settles this, and councils do write it differently, so it is a clause to read rather than a rule to assume.
It also says nothing about the dimensions of a lot. Frontage, depth, and whether a battle-axe handle is workable are not clause 4.1 questions — they come from the council’s development control plan and from whatever housing standards the lots are meant to support. A compliant area with an unusable shape is a compliant subdivision that cannot be built on.
What lot area buys under the Housing Code
Once a lot exists, its area is what the complying development pathway keys on. These are the Housing Code’s own tables for a dwelling house, and they are statewide — the same numbers in every council area where the pathway is available.
Read the bands carefully: the instrument writes the first as 200–250 m² and the next as >250–300 m², so the first band includes its lower bound and every later one excludes it. A lot of exactly 300 m² is in the second band, not the third.
| Lot area | Maximum gross floor area |
|---|---|
| 200–250 m² | 78% of lot area |
| >250–300 m² | 75% of lot area |
| >300–350 m² | 235 m² |
| >350–450 m² | 25% of lot area + 150 m² |
| >450–560 m² | 290 m² |
| >560–600 m² | 25% of lot area + 150 m² |
| >600–740 m² | 335 m² |
| >740–900 m² | 25% of lot area + 150 m² |
| >900–920 m² | 380 m² |
| >920–1,000 m² | 25% of lot area + 150 m² |
| Over 1,000 m² | 400 m² |
Clause 3.9. The staircase alternates flat caps with a formula rather than following one rule, so interpolating between bands gives the wrong answer on six of the eleven.
| Lot area | Minimum landscaped area |
|---|---|
| 200–300 m² | 10% |
| >300–450 m² | 15% |
| >450–600 m² | 20% |
| >600–900 m² | 30% |
| >900–1,500 m² | 40% |
| Over 1,500 m² | 45% |
Clause 3.13(1), as a percentage of lot area.
| Lot area | Primary road setback |
|---|---|
| 200–300 m² | 3 m |
| >300–900 m² | 4.5 m |
| >900–1,500 m² | 6.5 m |
| Over 1,500 m² | 10 m |
The operative primary road setback under clause 3.10(1) is the average setback of the two nearest dwelling houses on the same side of the road. The lot-size table above applies only where there are not two dwelling houses within 40 m. On an established street the table is usually the wrong number, and the neighbours are the right one.
Two further figures worth carrying: the maximum building height under the code is 8.5 m (clause 3.8), and a wall within 900 mm of a side boundary may not exceed 3.3 m (clause 3.10(7)).

Subdividing below the minimum
Clause 4.6 is the route, on the written test in clause 4.6(3): the applicant demonstrates that compliance is unreasonable or unnecessary and that there are sufficient environmental planning grounds, and the consent authority must be satisfied and keep a record. The public-interest test and Secretary concurrence were removed on 1 November 2023. A minimum lot size variation is among the harder ones to run: the standard is usually tied tightly to zone objectives about density and character, and the contravention is permanent in a way a height variation is not.
Clause 4.6(6) sets a hard limit here. In Zones RU1, RU2, RU3, RU4, RU6, R5, C2, C3 and C4, consent cannot be granted under clause 4.6 for a subdivision that would leave two or more lots below the minimum, or any lot below 90 per cent of it. Some LEPs also exclude clause 4.1 from clause 4.6 outright, and some make the exclusion partial; where that applies there is no variation pathway and the only route is a planning proposal to change the map. The complying development numbers in the section above cannot be varied under clause 4.6 at all (clause 4.6(8)(a)). Source: DPE, Guide to Varying Development Standards (November 2023), section 2.1.
