Small second homes

The Victorian Government has made it easier to build a small second home in residential and rural areas across Victoria – giving families more housing choice and boosting housing supply.

To make it easier to build a small second home, otherwise known as a small second dwelling, the Victoria Planning Provisions, all planning schemes and the Building Regulations have changed.

Some of the key features of a small second home include:

  • Floor area equal to or less than 60 square metres
  • Sited on the same lot as an existing dwelling
  • One small second dwelling per lot, however there may be more than one and this would be subject to a planning permit
  • Is self-contained, i.e. has a kitchen, bathroom, toilet and laundry facilities
  • No carparking required
  • Anyone can live in it or rent it out
  • Cannot be subdivided from the primary dwelling
  • Cannot be connected to reticulated gas
  • Meets siting requirements, including minimum garden area
  • Can be attached, detached or a conversion
  • Must have an access path from the front street

In most cases, a small second dwelling will not require a planning permit; however, a building permit is always required.

To support these changes, an updated Minister’s Guideline (MG-12): Siting and Design of Single Dwellings was published on the VBA website on 14 December 2023.

Living in a small second dwelling

Anyone. There are no limitations on tenancy for a small second dwelling. It can be rented, used as long-term or short-term accommodation or used by a family member and not rented out.

In addition, an owner looking to apply for a certificate of consent to build a small second dwelling is not required to intend to reside in the small second dwelling.

The residential tenancy requirements that apply to a dwelling will also apply to a small second dwelling. These include requirements relating to room sizes, facilities and smoke alarms. More inform about renting housing is available from Consumer Affairs Victoria.

Siting and development

The 60 square metres is the total floor area of the small second dwelling, measured from the outside of external walls or the centre of party walls, and includes all roofed areas.

You can convert a garage or other building into a small second dwelling if it:

  • Meets the definition of a small second dwelling;
  • Complies with any planning scheme requirements;
  • Complies with the building requirements.

It is advised to speak with your local council or a registered building surveyor for more information.

A ‘tiny home’ can be a lawful small second dwelling if it meets the specified planning and building requirements. Other regulations including local laws may apply. It is advised to speak with your local council or a registered building surveyor for more information.

The siting, design and amenity requirements for a small second dwelling are outlined in the planning scheme and Building Regulations 2018. The requirements in both systems are generally similar and can be found in:

  • Clause 54 of the planning scheme (One dwelling on a lot and small second dwellings) which applies in residential zones when a planning permit is required (except the Low Density Residential Zone).
  • Part 5 of the Building Regulations 2018 which applies in all other circumstances.

The minimum garden area requirement applies to all land in the Neighbourhood Residential Zone and to specified land in the General Residential Zone, and must be met when constructing or extending a small second dwelling.

More information about minimum garden area is available in Planning Practice Note 84 – Applying the minimum garden area requirement.

A lot with an approved building envelope may override the siting requirements in the planning and in Part 5 of the Building Regulations 2018.

More information about building envelopes is available in Building Practice Note SI-02 – Building Envelopes (PDF, 192.56 KB).

A planning permit may be required to remove, destroy or lop vegetation on your property (including trees and shrubs – either native or exotic species).

An easement on the land may mean there are restrictions on the use of that land.

For example, a utility company may use the land for pipes or power infrastructure, and you may not be able to build on that part of the land. Easements are recorded on each property’s Certificate of Title. You can purchase a Certificate of Title at Landata.

Small second dwellings cannot be connected to a reticulated natural gas supply.

The Victorian Government announced a ban on reticulated natural gas connected for all new homes in Victoria’s Gas Substitution Roadmap.

Dependent person’s units

A small second dwelling provides a similar function to a dependent person’s unit without the restrictions on tenancy and with proper siting, design and amenity requirements.

A dependent person’s unit must meet the new requirements in the planning scheme for a small second dwelling, unless it is subject to the transitional provisions in the planning scheme at Clause 52.04 (Transitional provisions for a dependent person’s unit).

It is advised to speak with your local council or a registered building surveyor for more information.

Existing, lawful dependent person’s units will remain lawful following the changes. They will not need to meet the requirements for a small second dwelling unless you want to change the use of the building to a small second dwelling.

It is advised to speak with your local council or a registered building surveyor for more information.

The transitional provisions in the planning scheme at Clause 52.04 (Transitional provisions for a dependent person’s unit) may apply.

It is advised to speak with your local council or a registered building surveyor for more information.

Agreements and covenants

A section 173 agreement sets out conditions or restrictions on the use or development of land, to achieve other planning objectives in relation to the land that may affect the development of a small second dwelling.

More information about section 173 agreements is available from the Department of Transport and Planning’s Agreements webpage.

A restrictive covenant is a private treaty or written agreement between landowners that limits the way land can be used and developed. If a registered restrictive covenant applies to your land, you will need to check if the construction of a small second dwelling would result in breach of a restrictive covenant.

State and local governments do not create or enforce restrictive covenants. This is done by owners of the land who benefit from the covenant.

More information about restrictive covenants is available from the Department of Transport and Planning’s Restrictive Covenants webpage.

Associated structures, fences and solar panels

Yes, however a planning and building permit may be required.

There are no fencing requirements between an existing dwelling and a small second dwelling. You can decide if you want to install fencing between the backyard of the existing dwelling and the small second dwelling, or provide a shared backyard.

Yes. Check with your local council to see if you are in a heritage area. A planning permit may be required for solar panels in heritage areas that are visible from the street, a lane or a park.

Development contributions

A small second dwelling will normally be exempt from these levies. Other contributions required by other government authorities such as water authorities will still apply.

Requirements under planning overlays

Services normal to a small second dwelling (for example cooling or heating systems, hot water service, shade sails and others) are exempt from requiring a planning permit. These services are listed in Clause 73.01 (General terms) of planning schemes.

Yes, any requirements that apply whether or not a planning permit is required continue to apply.

Yes, if a planning permit is required for a small second dwelling under the Neighbourhood Character Overlay.

Yes. A planning permit is required to alter or demolish your small second dwelling.

Local matters

Bin and recycling enclosures should be located on the property for convenient access by residents of a small second dwelling and the existing dwelling. Some councils provide residents with options to include the number of bins provided and to change the size of some bins at a cost.

Contact your local council for more information.

The local council is generally responsible for assigning street numbers to properties within the municipality.

The display of street numbers is the obligation of the property owner.

Street numbers must be clearly display in a prominent position to allow the property to be quickly and easily identified and located. This is most important in an emergency situation, but also for deliveries, service authorities and visitors to the property.

Contact your local council for more information.

You may be able to utilise existing utility services to the existing dwelling on the lot.

Contact your utility provider for more information.

Contact your local water authority to find out if fees apply.
