Key Takeaways
- Kitchen and bathroom renovations in NSW strata properties need permission before work starts
- Waterproofing, structural changes, ceiling work and work requiring other approvals can fall into major renovation territory
- A strong strata application should include scope, plans, contractor licence details, insurance, waterproofing details and work timing
- Apartment laundry changes may involve strata issues when plumbing, ventilation, waterproofing, drainage or fixed cabinetry are affected
- Checking by-laws before ordering materials or booking demolition reduces delay, dispute and rework risk
What Strata Renovation Rules Mean for Sydney Apartments
If you own an apartment, townhouse, villa, duplex, or other strata property in Sydney, a renovation is not only a design and building decision. It is also a strata approval process. This matters most for bathroom renovations, kitchen renovations, laundry renovations, and larger apartment renovations because these projects can involve plumbing, waterproofing, electrical work, flooring, walls, ventilation, and common property.
NSW Government strata guidance says kitchen or bathroom renovations need permission, and that work involving waterproofing, structural changes, or some common-property impacts can require a higher approval pathway. Always check your own scheme's by-laws and speak with the strata manager before work starts.
The Three Broad Renovation Categories
NSW strata guidance separates renovation work into broad categories. The exact pathway depends on your scheme, by-laws, and scope.
| Category | Typical Meaning | Renovation Example |
|---|---|---|
| Cosmetic work | Low-impact work that does not affect structure, outside appearance, or waterproofing | Painting internal walls or changing loose furniture |
| Minor renovation | Work that needs permission but is generally less complex than major work | Kitchen cupboard changes or some flooring changes, subject to by-laws |
| Major renovation | Work affecting structure, waterproofing, ceilings, outside appearance, or approvals under other laws | Bathroom renovation, waterproofing work, structural wall changes |

Bathroom Renovations in Strata Apartments
Bathrooms are usually treated seriously because they involve waterproofing, plumbing, floor wastes, wall linings, tiling, ventilation, and potential water escape into neighbouring lots or common property. A bathroom renovation should not start until you understand the approval process, documentation requirements, and any building-specific rules.
Expect strata to ask for details such as:
- Scope of works and plans
- Contractor licence and insurance details
- Waterproofing approach and certificate requirements
- Working hours and noisy-work windows
- Waste removal and lift protection method
- Responsibility for future maintenance where common property is affected
Kitchen Renovations in Strata Apartments
Kitchen renovations may appear less risky than bathrooms, but they can still involve plumbing, electrical work, flooring, common walls, exhaust requirements, appliance loads, and changes to cabinets fixed to shared walls. NSW guidance specifically lists kitchen renovations as work requiring permission.
If you are moving sinks, dishwashers, walls, exhaust paths, or flooring, check the strata pathway early. A simple cosmetic kitchen refresh may be straightforward, but a full layout change needs proper coordination.
Laundry Renovations and European Laundries
Laundry renovations can trigger strata issues when they involve drainage, ventilation, waterproofing, appliance stacking, noise, or conversion of a cupboard into a concealed laundry. A European laundry may be compact, but it still needs safe access to water, waste, power, ventilation, and moisture protection.
If your laundry sits beside a bathroom or kitchen, coordinate the work so services are planned together. This reduces the risk of duplicated trade visits and late design changes.
Documents to Prepare Before Applying
A strong strata application usually gives the owners corporation enough information to understand the scope, risk, contractor credentials, and disruption controls.
Prepare:
- A written scope of work
- Plans, markups, or drawings showing affected areas
- Product and fixture notes where relevant
- Licence and insurance details for the contractor
- Waterproofing details where wet areas are involved
- Proposed start date, working hours, and duration
- Waste removal and common-area protection method
- Any acoustic or flooring documentation requested by the scheme
Approvals, Contracts and Licensed Work
Some renovation work may need development consent, a complying development certificate, or other approval depending on the property and scope. NSW Government recommends checking with the local council or a registered certifier and using the NSW Planning Portal where relevant: Approvals needed for your building project.
For residential building contracts, NSW Government guidance says written contracts are required when the work is over the relevant value thresholds. Check current contract guidance here: Contracts for residential building work.
Common Strata Renovation Mistakes
Common mistakes include booking trades before approval, assuming a previous owner's renovation approval applies to your work, treating waterproofing as cosmetic, ignoring lift booking rules, failing to protect common areas, and submitting a vague scope that strata cannot assess.
Another mistake is designing for a freestanding house when the apartment has shared walls, limited access, stacked plumbing, restricted exhaust paths, and tight waste-removal rules. Apartment design should start with the building constraints, then solve the room layout.
Practical Rule
If the renovation touches plumbing, waterproofing, walls, floors, ceilings, exhaust, or common property, ask the strata manager before ordering materials or booking demolition.
