Victoria’s tenancy law names mould: structural mould breaches a rental minimum standard and is an urgent repair a renter can arrange up to $2,500. For owners, it is a winter drying problem.
Victoria’s tenancy law names mould in terms. For a Melbourne renter that turns mould from a negotiation into a right with a dollar figure and a deadline. For an owner it is a winter drying problem with a statutory owners-corporation duty behind it when the water came from common property.
A Melbourne renter’s rights, in order
| Question | Answer | Provision |
|---|---|---|
| Must the property be free of mould? | Every room must be free from mould and damp caused by or related to the building structure | Regs sch 4 item 8 |
| Is it an urgent repair? | Yes: the presence of mould or damp caused by or related to the building structure, and any failure to meet the minimum standards | RTA s 3(1) |
| How fast must it be fixed? | Urgent repairs immediately; non-urgent within 14 days of a written request | Consumer Affairs Victoria |
| Can I arrange it myself? | If you took reasonable steps and could not get the rental provider to act | RTA s 72(1) |
| How much can I spend? | Up to $2,500 | Regs reg 32 |
| When am I repaid? | Within 7 days of written notice | RTA s 72(2)(c) |
| Should I have been told about it? | Yes, if the provider received a repair notice, in the last 3 years, relating to mould or damp in the premises | Regs reg 16(2)(c) |
The qualifier that runs through every row is “caused by or related to the building structure”. A leaking roof, rising damp, a failed shower membrane or no working exhaust fan are the kinds of cause the words point at; mould from drying clothes inside with the windows shut all winter is harder to attribute to the building. Whether a particular case qualifies is for VCAT, not this site.
The minimum standard and the urgent repair
Residential Tenancies Regulations 2021 (Vic) sch 4 item 8 · authorised version 009, amendments as at 30 June 2026, read 22 September 2026
Every room in the rented premises. It is one of the rental minimum standards, and Consumer Affairs Victoria says that from 25 November 2025 a property must meet them before it is advertised.
Residential Tenancies Act 1997 (Vic) s 3(1), definition of urgent repairs, para (k)(ii) · authorised version 114, as at 9 September 2026, read 22 September 2026
Listed as fault or damage that makes the premises unsafe or insecure. The same definition includes a burst water service, a serious roof leak, flooding or serious flood damage, and a failure to comply with the rental minimum standards.
Put together, those two provisions mean structural mould in a Melbourne rental is both a breach of a minimum standard and an urgent repair. Consumer Affairs Victoria says urgent repairs must be made immediately. Put the request in writing, with photographs, and keep a copy.

The most a renter can arrange and be reimbursed for urgent repairs, when the rental provider cannot be got to do them (s 72(1)); reimbursement is due within 7 days of written notice (s 72(2)(c)). Consumer Affairs Victoria says urgent repairs must be made immediately and non-urgent repairs within 14 days of a written request.
If the rental provider cannot be got to act, you can arrange the repair and be repaid the reasonable cost up to $2,500. For mould that can mean two trades: the one who fixes the cause (a plumber or roofer) and the one who removes the mould and dries the structure, often two separate invoices. Use licensed trades and keep every invoice.

Apartments: the owners corporation’s duty
Owners Corporations Act 2006 (Vic) s 46 · authorised version 024, as at 9 September 2026, read 23 September 2026
And the chattels, fixtures, fittings and services related to it. Section 47(1) extends the duty to a service in a lot that benefits more than one lot and the common property, and s 59(1) requires reinstatement and replacement insurance for all buildings on the common property.
So a leak from a roof, a riser or other pipes that are common property is the owners corporation’s to repair, and its building policy is the one that responds. Where the apartment is rented, the Residential Tenancies Act lets the rental provider join the owners corporation to a Tribunal application about damage to adjoining common property (s 75A). The strata page covers how the two insurance policies meet.
Melbourne’s mould season is winter
Bureau of Meteorology, climate statistics for Melbourne Airport (086282) · prepared 17 September 2026, read 23 September 2026
Mean 9am relative humidity, the highest month, followed by July (81%) and May (79%); the annual mean is 72% (1970–2010). Mean annual rainfall is 536.2 mm on 86.1 rain days.
Melbourne’s most humid mornings are in June, July and May. Damp winter air slows drying and feeds condensation on cold surfaces. After a winter leak, the drying takes longer than the same job in summer; the day count is the number to ask about on the quote.
Cleaning it: the Better Health Channel’s method
Better Health Channel (Vic), Mould removal at home · reviewed 8 October 2020, read 22 September 2026
“Do not dry brush the mouldy area”, and vacuum only with a HEPA filter. It lists good ventilation, a shower cap, rubber gloves, eye protection, overalls, suitable footwear and a P1 or P2 mask; says pregnant women, children and people with weakened immune systems or chronic lung disease should not remove or be present; finds household detergent or white vinegar sufficient in many cases; warns never to mix bleach with ammonia, acids or other cleaners; and says to consult a mould remediation professional if large areas of regrowth occur.
On testing, the same department’s position is that where mould is visible it is generally not considered necessary to test for it in the home (Better Health Channel (Vic), Mould and your health). After a flood, it advises asking your insurer before cleaning or disposing of water- or mould-damaged items. The mould removal guide sets the Victorian guidance beside NSW, Queensland and Western Australia.

None of those figures is priced for Melbourne, and no Melbourne premium is published here. For a renter, the useful comparison is with the $2,500 urgent repair cap: a small-room clean sits well inside it; a job that includes drying a wet wall may not. Two rooms dried over five days with one HEPA unit is $2,669 excluding GST on the published rate card, before the mould work itself.

Common questions
Is mould an urgent repair in Victoria?
Yes, where it is caused by or related to the building structure. The definition of urgent repairs in s 3(1) of the Residential Tenancies Act 1997 includes fault or damage that makes rented premises unsafe or insecure, including the presence of mould or damp caused by or related to the building structure, and a failure to comply with the rental minimum standards.
How much can a Melbourne renter spend on urgent repairs?
Up to $2,500, the amount prescribed by reg 32 of the Residential Tenancies Regulations 2021, where the renter has taken reasonable steps to get the rental provider to do the repair immediately and could not. The rental provider must reimburse the reasonable cost within 7 days of written notice.
Does a Victorian landlord have to tell me about past mould?
Reg 16(2)(c) of the Residential Tenancies Regulations 2021 requires a rental provider to disclose to a rental applicant if they have received a repair notice in the last 3 years relating to mould or damp caused by or related to the building structure.
Who fixes mould in a Melbourne apartment?
If the water came from common property, the owners corporation, which must repair and maintain common property and its services under s 46 of the Owners Corporations Act 2006, and must insure the buildings under s 59. Mould inside your lot from your own fixtures is yours.
Why is mould worse in Melbourne in winter?
On the Bureau of Meteorology's Melbourne Airport record, mean 9am relative humidity peaks at 83% in June, 81% in July and 79% in May. Damp winter air slows drying and feeds condensation.
Can I remove mould myself in Victoria?
The Better Health Channel says small to medium areas may be removed at home, with ventilation and protective clothing including a P1 or P2 mask, and that pregnant women, children and people with weakened immune systems or chronic lung disease should not remove it or be present. Do not dry brush it.
