Willoughby City DCP: the dwelling controls, as published.
4 controls for low-density residential — dwelling houses, taken from Willoughby Development Control Plan 2023 (WDCP), Part B: Residential Development — Attachment 1: Controls for development in the R2 zone. As at 2026-08-29.
NSW has no statewide dwelling setback or site-coverage standard. The LEP sets zone, height and FSR; the numbers that shape a build sit in each council's DCP — here, the 4 that Willoughby City publishes numerically. Anything its DCP assesses on merit rather than a fixed number is absent from this table: not a zero, and not a permission.

Scope: R2 dwelling houses. These are the controls for R2, Willoughby City’s low-density residential zone. Do not apply these figures to a dual occupancy, duplex, secondary dwelling or multi-dwelling housing development — those are assessed under different standards, which Feasibly has not codified.
What qualifies these Willoughby City controls?
- Landscaped area is FORMULA-based, not a flat % — e.g. (0.35 × site area) − 20m² for 200–400m², (0.6 × area) − 120m² for 401–600m² (Willoughby DCP §3.2); min 20% of the landscaped area is deep soil. Not codified as a tier to avoid misrepresenting the formula — see the DCP.
- SITE COVERAGE: the WDCP sets no site-coverage percentage for R2 dwelling houses. Bulk is controlled instead by FSR (sliding by lot area, LEP Cl.4.4A Area 1: <200m²=0.65:1 down to ≥800m²=0.40:1) plus the landscaped-area controls. LEP building height 8.5m (Cl.4.3). Hence all site_coverage fields are null.
- LANDSCAPED AREA is formula-based, not a flat percentage: the tier 'pct' captures the multiplier only. Exact formulas: ≤200m²=0.25×site; 201–400m²=(0.35×site)−20m²; 401–600m²=(0.6×site)−120m²; 601–1000m²=(0.525×site)−75m²; 1001–1500m²=(0.6×site)−150m²; >1501m²=0.5×site. Min dimension 1m; the landscaped area must include a minimum 20% deep-soil zone (remainder 'soft' landscaping ≥600mm depth); ≥50% of the landscaped area must be behind the building line; deep-soil forward of the building line ≥70% (lot ≥18m wide) / ≥50% (lot <18m wide). landscaped_deep_soil set false because the tiered control is total landscaped area, not a pure deep-soil control.
- FRONT setback (front_setback_m=null): governed by 'the average of the 2 adjoining dwellings', with a lot-area fallback table (3 / 4.5 / 6.5 / 10m) — no single fixed value, so captured in front_setback_note. Classified-road=9m, public-reserve=3m, battle-axe=3m.
- SIDE setback stored as the stated 900mm (0.9m) minimum; it increases with lot width and building height (e.g. lots >10–18m wide taller than 4.5m = (H−4.5)/4+0.9m; >18–24m = 1.5m base; >24m = 2.5m). Walls within 900mm of the side boundary capped at 3.3m (detached max 4.5m).
- REAR setback (rear_setback_m=null): varies by lot AREA and building HEIGHT (not frontage), ranging 3m (≤300m², ≤4.5m high) up to 15m (>1500m², 4.5–8.5m high); full matrix in source_excerpts. Neither the flat nor by-frontage schema fits, so left null with detail preserved.
- SECONDARY (corner) street setback stored as the ≤600m² band value (2m); tiers are ≤600m²=2m, >600–1500m²=3m, >1500m²=8m.
- MIN BOUNDARY: minor structures (aerials/awnings/air-conditioners and the like) have a 450mm minimum side/rear setback; structures within 900mm of a rear lane set back 50% of the boundary. min_boundary_setback_m left null as these are ancillary-structure controls, not the dwelling envelope.
- PRIVATE OPEN SPACE reduction is by lot WIDTH, not lot area: 24m² for lots >10m wide, reduced to 16m² for lots ≤10m wide; minimum length/width 3m. pos_small_site_max_area_sqm left null because the qualifying threshold is a width (10m), not an area; pos_small_site_min_sqm=16 records the reduced minimum.
- SOURCE/FETCH: Part B is the current WDCP 2023 as amended (Doc Set ID 7229492, version 09/07/2025), linked from the council's WDCP page. The Zyte fetch helper returned '520 Website Ban' on this 13MB PDF while small WDCP PDFs (Part A, Part J) fetched fine — a size/timeout issue, not a content problem; the file was retrieved via direct download of the same official council URL and all table numbers were verified from the rendered PDF pages (pp.53–57 printed).

How reliable is this Willoughby City DCP data?
These values were machine-extracted from the source DCP and have not been independently re-checked. Treat them as screening grade: good enough to compare councils and to know which questions to ask, not a substitute for reading the clause before you rely on it. This is a different and lower tier of confidence than our Victorian zone schedules, which are read and verified from the source planning scheme by a person. We do not present the two as equivalent.
A council's DCP can be amended at any time and this page reflects the document as at 2026-08-29. Where a control is absent above, the DCP either sets no number or assesses that parameter on merit.

Willoughby City planning controls — common questions
Do these Willoughby City controls apply to a duplex or dual occupancy?
No. The figures on this page are Willoughby City’s dwelling-house controls. A dual occupancy, duplex, secondary dwelling or multi-dwelling housing development is assessed under different standards — Feasibly has not codified those, so do not apply the numbers above to one.
Which zone do these Willoughby City controls apply to?
R2 Low Density Residential — Willoughby City’s low-density residential zone. Confirmed against the zones the Willoughby City LEP actually contains. This page presents the low-density residential case; some DCP sections also cover other residential zones, and the source above names the zones it applies to.
What planning controls does Willoughby City publish for dwellings?
Willoughby City publishes 4 dwelling controls in Willoughby Development Control Plan 2023 (WDCP), Part B: Residential Development — Attachment 1: Controls for development in the R2 zone: front setback, secondary street setback, side setback, private open space. Each value and its clause reference is listed on this page, as at 2026-08-29.
Does NSW have a statewide dwelling setback standard?
No. The Local Environmental Plan sets zone, building height and floor space ratio, but the numbers that shape a dwelling — setbacks, site coverage, landscaped area and private open space — sit in each council’s Development Control Plan. That is why these figures are published per council rather than per state.
How reliable are these Willoughby City figures?
They are machine-extracted from Willoughby Development Control Plan 2023 (WDCP), Part B: Residential Development — Attachment 1: Controls for development in the R2 zone and have not been independently re-checked, so treat them as screening grade — good enough to compare councils and to know which questions to ask, not a substitute for reading the clause. This is a lower confidence tier than our Victorian schedules, which a person reads and verifies from the source scheme.
Do these controls apply to every property in Willoughby City?
No. These are the council-wide published figures for low-density residential — dwelling houses. The zone, any overlays and the consent triggers that actually apply depend on the individual parcel, and a control absent from this page means the DCP either sets no number or assesses that parameter on merit — not that the requirement is zero.
