No, not usually. A bathroom renovation in NSW may be exempt development if it is limited to eligible internal alterations and meets all requirements under the NSW planning rules. Approval may be required if the work affects the building’s structure, fire safety or compliance, or falls outside those requirements.
Work that may be exempt
Straightforward internal renovations may qualify as exempt development, including:
- replacing toilets, basins, baths, showers, taps and cabinetry
- replacing tiles, wall or floor linings and other finishes
- renewing waterproofing
- relocating fixtures where the overall work still satisfies the exemption requirements.
Exempt development does not need development consent or a complying development certificate. However, the work must meet the relevant standards in the NSW State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 and other applicable building requirements.
When approval may be required
Ask the relevant council or a registered certifier to assess the project if it involves:
- adding, moving or removing walls
- changing the room’s size or configuration
- affecting load-bearing or other structural elements
- affecting fire-resisting construction, particularly in an apartment building
- altering required ventilation, natural light, doors or windows
- a heritage-listed property or property subject to specific planning controls.
Work that is not exempt may require a complying development certificate or development consent through a development application. The correct pathway depends on the property and the complete scope of work.
Do not remove walls or penetrate apartment floors, walls or ceilings before a qualified professional checks structural elements, concealed services and fire separation.
Separate plumbing and strata requirements
Planning exemption does not remove trade licensing, building compliance or strata obligations.
Plumbing and drainage work must be completed by an appropriately licensed contractor where required. Waterproofing must also comply with applicable building and licensing requirements. Safe homeowner involvement should be limited to planning the scope and observing accessible conditions, not altering pipes, waterproofing, structures or concealed services.
For strata property, owners corporation approval may be required where the renovation affects waterproofing, common property or other regulated building elements. This is separate from council planning approval.
Before demolition, document every fixture relocation, wall alteration, penetration and ventilation change. Check current NSW Planning Portal guidance, then ask the relevant Sydney council or a registered certifier to confirm the approval pathway. Our licensed Sydney plumbing team can assess the plumbing scope, but planning approval must be confirmed by council or a registered certifier.
