Sample site report
What you get: one real lot, clause by clause
This is the working behind a site review on a real job — a single-storey rear extension in Monterey, later approved as complying development. The street address is withheld; the numbers aren't.
Every line names the clause it turns on, so you, your builder or your certifier can check it. Where the mapping can't settle something, the report says so rather than guessing.
The zone, lot area and width pass the Housing Code's land test, and no layer that removes complying development is mapped over the lot. Floor area is generous on a lot this size — 241.68 m² allowed against 144.96 m² proposed — so the control that actually shaped the plan is the 15% landscaped-area minimum on a block already mostly covered by house and garage.

2. Complying development audit
State Environmental Planning Policy (Exempt and Complying Development Codes) 2008, Part 3 Housing Code, alterations and additions to a dwelling house.
| Clause | Requirement | This site | Result |
|---|---|---|---|
| cl 3.1(3)(a) | Lot in Zone R1, R2, R3, R4 or RU5 | R2 | Complies |
| cl 3.1(3)(b) | Lot area not less than 200 m² | 366.7 m² | Complies |
| cl 3.1(3)(c) | Lot width at least 6 m at the building line | approx. 13.5 m | Complies |
| cl 1.19(1)(a) | Not in a heritage conservation area | Not mapped | Complies |
| cl 1.19(1)(c) | Not Class 1 or 2 on the Acid Sulfate Soils Map | Mapped — class confirmed before lodgement | Confirm |
| cl 3.8 | Maximum height 8.5 m above existing ground | Single storey | Complies |
| cl 3.9 | Maximum GFA, lot >350–450 m²: 25% of lot area + 150 m² = 241.68 m² | 144.96 m² proposed | Complies |
| cl 3.10(4) | Side setback, lot width >10–18 m, building to 4.5 m high: 900 mm | Complies on the approved CDC plans | Complies |
| cl 3.10(10) | Rear setback, lot >300–900 m², building to 4.5 m high: 3 m | Complies on the approved CDC plans | Complies |
| cl 3.13(1) | Minimum landscaped area, lot >300–450 m²: 15% = 55.0 m² | 96.51 m² (26.32%) | Complies |
| cl 3.13(3)(a) | Lot width 18 m or less: 25% of the area forward of the building line landscaped | Street frontage unchanged by the works | Complies |
| cl 3.30(2) | Acid sulfate Class 3 or 4: excavation no deeper than 1 m | Complies on the approved CDC plans | Complies |
A full report runs every clause in the code — siting, privacy screens, decks, car parking, earthworks, drainage and the Schedule 3 local variations — and marks each as complies, fails or confirm.
3. If the CDC route had closed
The fallback is a development application to Bayside Council under the Bayside LEP 2021 and DCP. On the mapping, the scheme sits well inside the LEP's 0.5:1 floor space ratio (about 183 m² on this lot) and the 8.5 m height limit. The 450 m² minimum lot size matters only for subdivision or a second dwelling, not for an extension.
A DA would add a Statement of Environmental Effects, shadow diagrams, neighbour notification and council's assessment period.
4. What to verify before lodging
- Acid sulfate soils class — cl 1.19(1)(c) excludes Class 1 and 2 land; Class 3 or 4 caps excavation at 1 m.
- Section 10.7 planning certificate — the council's own record of whether complying development can be carried out on the lot.
- Survey — lot width at the building line, existing setbacks and levels. The cadastre is accurate to about a metre, not to the 900 mm a side setback turns on.
- Sewer and stormwater — Sydney Water build-over and the lawful point of discharge.
