Ten things forums get wrong about rooming houses in Victoria — with the section numbers

“Stay at three leases and it isn’t a rooming house”

This is the most repeated piece of rooming-house advice on Australian property forums: let a house to three people on three separate agreements and it stays an ordinary rental; the fourth lease is what turns it into a rooming house. It appears in several costumes — three rooms, three tenants, three bedrooms — and it is often given as a way to keep a converted house out of the licensing regime altogether.

The Residential Tenancies Act 1997 s 3(1) says something different. A rooming house is “a building, other than an SDA dwelling, in which there is one or more rooms available for occupancy on payment of rent — (a) in which the total number of people who may occupy those rooms is not less than 4”. The unit of count is people who may occupy the rooms. The number of agreements is not mentioned; nor is the number of rooms. A couple in one room counts as two people, and a building whose rooms can hold four is a rooming house even if only three agreements have been signed. Section 19 goes the other way: an owner of a building with rooms for rent and fewer than four people may ask the Minister to declare it a rooming house anyway.

On a plan or in a contract the myth is expensive. A “three-lease” arrangement over a four-bedroom house does not remove the operator licence obligation under the Rooming House Operators Act 2016 s 7(1) — 240 penalty units ($50,184 at $209.10 a unit) or two years’ imprisonment for an individual — or the council registration duty under the Public Health and Wellbeing Act 2008 s 67. PremiumRea, which shares a founder with DollarBuild and keeps the group’s statutory reference on this point, publicly withdrew its own earlier “stay at three leases” guidance for exactly this reason: rooming house rules in Victoria. Our building-side version is what the building itself must have.

“Four housemates on one lease makes the house a rooming house”

The mirror-image myth is just as common, usually from a nervous landlord: four unrelated adults have signed one residential rental agreement for a house, so the house has “become” a rooming house, must be Class 1b, and the owner now needs a licence. Some threads go further and tell owner-occupiers that housing four friends puts them in the same position.

Section 3(1) is about rooms “available for occupancy on payment of rent” and the people who may occupy those rooms. Consumer Affairs Victoria draws the practical line: a rooming house is “a building where 4 or more people can live in rented rooms”, individual residents “usually have separate agreements with the rooming house operator”, and it “is different to a share house, boarding house or sub-let”. The same page states that standard residential rental agreements “cannot be used in a rooming house unless someone is renting a self-contained apartment”. In a share house the whole premises are let to co-renters under one residential rental agreement; in a rooming house the operator lets rooms, individually, under rooming house agreements governed by Part 3 of the Act.

What changes the classification is how the building is let, not the day the headcount reaches four. The moment rooms in a building are let individually to four or more people, all three obligations engage at once — registration, licence, and the two sets of minimum standards. There is no way to “grow into” a rooming house one agreement at a time and no grace period for the fourth. Where a configuration genuinely sits on the line, the question belongs to Consumer Affairs Victoria or a lawyer, not a forum, and the s 19 declaration power exists for the marginal building.

“The Act counts people, the Code counts square metres, the Scheme counts bedrooms — and not one of them counts leases.”

“Class 1b means a maximum of three tenants”

Forums routinely treat the National Construction Code classes as tenant counts: “Class 1a lets you have up to three tenants; Class 1b is for four or more”. From there the conversation slides into “so keep it 1a and stay at three”, which is the first myth wearing a building-code badge.

NCC 2022 Volume One A6G2 defines the classes by what the building is and how big it is. Class 1a is a detached house, or one of a group of attached dwellings each separated by a fire-resisting wall. Class 1b is “a boarding house, guest house, hostel or the like that would ordinarily accommodate not more than 12 people; and have a total area of all floors not more than 300 m²”. Above either number the building is Class 3 under A6G4. Nothing in the classification counts leases, and it is a building surveyor, not a landlord, who classifies. The two Class 1b numbers — 12 people and 300 m² — happen to be the same numbers Clause 52.23 uses, which is why a purpose-built rooming house is drawn to both at once; the detail is in our NCC Class 1b guide.

Why it matters on a plan: a house certified as Class 1a and then let by the room to four or more people is a change of use that a building surveyor must assess, with the Class 1b fire, alarm, exit and access provisions applied before the change is lawful. Why it matters in a contract: a Class 1b building permit or occupancy permit does not license anyone to operate a rooming house, and a rooming house operator licence does not classify a building. They are two systems answering two different questions, and a compliant rooming house needs the right answer from both.

“One bathroom for every six residents”

Ratios circulate with confidence and without a source: one bathroom per six, one per five, one toilet per eight. They are usually quoted when someone is sizing a conversion and wants to know how many bathrooms to add.

The number is in the Public Health and Wellbeing (Prescribed Accommodation) Regulations 2020, reg 20: a proprietor “must provide at least one toilet, one bath or shower and one wash basin for every 10 people or fraction of that number of people occupying the accommodation”, with a penalty of 20 penalty units. Regulation 11 supplies the room rules that sit next to it — no bedroom under 7.5 m² (reg 11(2)), and for stays over 31 days one person in a bedroom under 12 m², or two people in a bedroom of 12 m² or more plus one more for every additional 4 m² (reg 11(3)). The Residential Tenancies (Rooming House Standards) Regulations 2023 add no ratio; their reg 11 requires a privacy latch on every shared toilet and bathroom door.

On a plan the floor is easy to state and easy to miss. A twelve-resident house needs two toilets, two baths or showers and two wash basins under reg 20; a nine-room ensuite design sits far above that floor, which is why the ratio only ever bites on legacy conversions. In a contract to buy an existing rooming house, an advertised configuration such as “twelve residents, one bathroom” is non-compliant on its face and should be read as a rectification cost, not a feature. The full room-by-room list is in our minimum standards guide.

• —1 to 10 people occupying: 1 toilet, 1 bath or shower, 1 wash basin (reg 20)
• —11 to 20 people occupying: 2 of each (reg 20 — “or fraction of that number”)
• —No bedroom under 7.5 m² of floor area, bathrooms and toilets excluded from the measurement (reg 11(2), 11(6)(c))
• —Stays over 31 days: 1 person under 12 m²; 2 people at 12 m², plus 1 per extra 4 m² (reg 11(3))

“Council registration is annual”

Investors budget a yearly registration and a yearly inspection, and some threads warn that a registration “lapses every twelve months”. The figure is presented as a statewide rule.

The Public Health and Wellbeing Act 2008 s 67 requires the proprietor of prescribed accommodation to register it with the council “on a periodic basis”, with a penalty of 60 penalty units for an individual and 300 for a body corporate; reg 6(f) of the 2020 Regulations lists rooming houses as prescribed accommodation, and reg 5 adopts the RTA s 3(1) definition. The period is set in s 74(1)(d): the council determines it, “being a period not greater than 3 years”, and it must be specified on the certificate. Some councils choose twelve months; the Act does not. The operator licence runs on a separate clock: the Rooming House Operators Act 2016 s 20(3) allows an initial licence of not more than three years and a renewal of three to five years, and Consumer Affairs Victoria issues initial licences for three years.

Two clocks, two instruments, two registers. On the contract file that means a current council certificate showing its expiry, a licence number that appears on the CAV public register of rooming house operators, and a note of which council fee schedule applies (fee units reset each 1 July). A buyer of an operating rooming house should ask for all three before exchange; the sequence for a new building is in registering and licensing a new rooming house.

“A company doesn’t need an operator licence”

Two versions circulate: buy the property in a company and “the licence rules are for individuals”, or “the manager holds the licence, the owner does not need one”. Both come up when someone is structuring a purchase.

The Rooming House Operators Act 2016 s 3(1) defines a rooming house operator as “a natural person who, or a body corporate that, conducts the business of operating a rooming house, whether or not the rooming house operator owns the property”. Section 7(1) then provides that “a person other than a registered housing association or registered housing provider must not conduct the business of operating a rooming house without a licence”, and sets the penalty in two tiers: 240 penalty units or two years’ imprisonment for a natural person, 1,200 penalty units for a body corporate — $250,920 at the 2026-27 unit value. Consumer Affairs Victoria confirms the mechanics: only the person or body corporate operating the house is licensed, a company applies in its own name, and its officers are assessed as relevant persons.

The licence follows whoever conducts the business. If the company runs the house, the company holds the licence; if a management company operates it in its own right, that company is the licensee; an owner who leases the building to a licensed operator is not the operator, but is not out of the picture either — Consumer Affairs Victoria lists a 60-penalty-unit offence for an owner who fails to notify the council of suspected unlicensed rooming house use in their building. In a management agreement, name the licensed entity and its licence number, and check both on the public register.

“A rooming house always needs a planning permit”

Neighbours say it as a complaint (“how was this approved without notice?”) and investors say it as a deterrent (“council will never approve it, and every neighbour can object”). Both assume a permit application is the only route.

Clause 52.23 of every Victorian planning scheme says otherwise. Clause 52.23-2 (as amended by VC274, 28 February 2025) removes any requirement in the Activity Centre, Capital City, Commercial 1, General Residential, Housing Choice and Transport, Mixed Use, Neighbourhood Residential, Precinct, Residential Growth and Township zones to obtain a permit to use land for a rooming house, provided the zone’s condition for the use is met, “the total floor area of all buildings on the land, measured from the outside of external walls or the centre of party walls, does not exceed 300 square metres, excluding outbuildings”, “no more than 12 persons are accommodated” and “no more than 9 bedrooms are provided”. Clause 52.23-3 (VC257, 25 February 2025) removes the buildings-and-works permit in six of those zones on further limbs: bedrooms only accessible from within the building, the garden area of the zone in the General and Neighbourhood Residential zones, and “shared entry facilities and common areas, including a kitchen and living area”. Latrobe City’s planning FAQ states the consequence plainly: where the exemption applies there is no notice to neighbours and no objection avenue, and Clause 52.06 requires one car space per four bedrooms — two for an exempt nine-bedroom house.

The limits are what the forums leave out. Overlays keep their own triggers — heritage, bushfire, flood and design overlays can each require a permit on an otherwise exempt lot (which overlay codes change the pathway). The 300 m² counts every building on the land to the outside of external walls, so an attached garage counts and only outbuildings are excluded. A building permit is always required — the Building and Plumbing Commission’s position is that all building work needs one unless the Building Regulations 2018 exempt it. And the building must actually be a rooming house within the planning definition, which is the next myth. The clause-by-clause reading is in building a new rooming house without a planning permit.

• —Use exemption, 52.23-2: ten zones; zone condition met; ≤ 300 m² all buildings excluding outbuildings; ≤ 12 persons; ≤ 9 bedrooms
• —Buildings and works exemption, 52.23-3: General Residential, Housing Choice and Transport, Mixed Use, Neighbourhood Residential, Residential Growth and Township zones; ≤ 9 bedrooms; bedrooms accessed only from inside; ≤ 300 m²; garden area in GRZ and NRZ; shared entry, kitchen and living area
• —Still required: a building permit; compliance with every overlay on the planning certificate; Clause 52.06 car parking at one space per four bedrooms

“Ensuites turn it into a block of studios”

This myth runs in both directions. One camp says rooms must share a bathroom “or it isn’t a rooming house any more”. The other says the opposite and worse: give every room a kitchenette as well as a bathroom, call the result a rooming house, and collect studio rents under the same exemption.

The Tribunal drew the line in Studio Homes Victoria Pty Ltd v Brimbank CC [2022] VCAT 1371. The applicant sought a declaration under s 149A of the Planning and Environment Act 1987 that no permit was needed for nine studios, each with an ensuite and a kitchenette of roughly two metres with a sink, fridge and its own hot water unit, each with its own electricity and water meter and letterbox, alongside a shared 3 m by 4 m kitchen and meals area and a shared laundry. The Tribunal held that the studios were more appropriately characterised as self-contained accommodation — residents could rely exclusively on the private facilities in each studio, and the real and substantial use of the land was a series of self-contained studios with common facilities available at a resident’s election — so the building was not a rooming house and the Clause 52.23 exemption did not apply. The planning definitions explain why: Clause 73.03 defines a rooming house as land used for a rooming house as defined in the Residential Tenancies Act 1997, nested under “Residential building”, which expressly excludes a “Dwelling”; and a dwelling is “a building used as a self-contained residence which must include a kitchen sink, food preparation facilities, a bath or shower, and a toilet and wash basin”. Wyndham City’s planning guidance puts it in one sentence: a room with kitchen, bathroom and toilet is a self-contained apartment, not a room within a rooming house.

So the line is not the bathroom; it is the kitchen. An ensuite gives a room a bath or shower, toilet and basin and leaves it a room. A sink and food-preparation bench inside the room supply the missing elements of a dwelling, and a building of dwellings is assessed as dwellings — a permit application, notice, and objections. That is the reading DollarBuild’s Rooming House 300 is drawn to: nine rooms, each with an ensuite and none with a kitchenette, a shared kitchen, laundry and living room that residents must actually use, nine bedrooms, not more than twelve residents, and a total floor area held at 300 m². The trade-off is deliberate — the ensuite is what the 52.23-3 shared-facilities limb permits, and the kitchenette is what the Tribunal said it does not.

“GST applies like a commercial property”

Because the loan is often written as a commercial facility and the building is Class 1b, forums conclude the asset is “commercial” for tax: claim the GST on the build, charge GST on the room rents, treat it like a shop. Some go the other way and assert that rooming houses are always GST-free, full stop.

The Australian Taxation Office states the starting point: “if you rent out residential premises for residential accommodation, your rent is input taxed and you don’t include GST in the rental charge”, and “you also can’t claim credits for the GST included in any costs relating to the rental”. The exception is commercial residential premises — hotels, motels, inns, hostels, boarding houses and similar establishments — whose sale and lease are taxable. Which side a rooming house falls on is a question of fact under GST Ruling GSTR 2012/6. Paragraph 12 lists the characteristics that point to commercial residential premises: commercial intention, multiple occupancy, holding out to the public, accommodation as the main purpose, central management, accommodation offered in the operator’s own right, provision of services, and occupants who have the status of guests rather than tenants with an exclusive right to their room. Paragraph 127 records that the Commissioner’s earlier general advice to the boarding and rooming house industry — that supplies to residents who are not guests are input taxed under s 40-35(1) — was revised after ECC Southbank, with a transitional arrangement in paragraph 128. Separately, the sale of new residential premises is a taxable sale.

The point for a build contract is that the lender’s word “commercial”, the NCC class and the planning exemption say nothing about GST. The GST Act asks whether the premises are residential premises let as a home or something that operates like a hotel, and a nine-room house let under rooming house agreements with quiet enjoyment, no meals and no reception desk is assessed on those facts, not on its loan type. Get the classification in writing from a tax adviser, or by private ruling, before a feasibility is priced on GST credits it may not be entitled to. This article states the ATO’s published position and is not tax advice.

“No planning permit means no oversight”

Neighbours say “nobody checks these places” and some investors hear it as “no permit, no inspections”. The premise is that the Clause 52.23 exemption removes the state from the building.

It removes one application. Everything else remains. All building work needs a building permit from a registered building surveyor unless the Building Regulations 2018 exempt it, and the surveyor classifies and inspects to Class 1b. The Public Health and Wellbeing Act 2008 s 67 requires council registration (60 or 300 penalty units), reg 21 of the 2020 Regulations requires a register of occupants with arrival and departure dates, and reg 11 caps occupants per bedroom by floor area. The Rooming House Operators Act 2016 s 7(1) requires the operator licence, and Consumer Affairs Victoria publishes the public register. Two sets of minimum standards apply — the 2020 public-health regulations and the Residential Tenancies (Rooming House Standards) Regulations 2023, including a fixed heater in every resident’s room from 1 December 2025. Consumer Affairs Victoria states that inspections are unannounced and may be random or complaint-driven, carried out by council officers, Consumer Affairs Victoria, building surveyors and the fire authority, and that a building surveyor may issue a building notice or building order.

The prosecutions are real. Monash City Council reports that on 5 March 2025 two operators of an unregistered rooming house in Ashwood were convicted in the Moorabbin Magistrates’ Court under the Public Health and Wellbeing Act 2008 and the 2020 Regulations for operating unregistered, exceeding the maximum occupants per bedroom and failing to provide vermin-proof receptacles, fined $2,500 each with more than $6,700 in costs, and disqualified from holding a rooming house operator licence for at least five years. In a contract to buy an “operating” rooming house, require the current registration certificate, the licence number as it appears on the public register, and the outcome of the last inspection. The order of operations for a new building is in registering and licensing a new rooming house.

• —Inspectors check: the operator’s licence with the Business Licensing Authority; bond lodgement with the RTBA; bathroom numbers, water, pests, rubbish; smoke detectors, emergency lighting and exits; repair and ventilation (CAV)
• —Records the proprietor must keep: a register of occupants with names, addresses, arrival and departure dates (PA Regs 2020 reg 21)
• —Consequences on the record: fines and costs, a conviction, and disqualification from holding an operator licence (Monash, 2025)
