Tiny houses have become popular in Australia for their affordability, sustainability, and simplicity. However, before buying, it’s crucial to understand tiny house regulations. These rules vary across regions, so local knowledge is essential. In this article, we will discuss the regulation of tiny houses in NSW.
Why Understanding Tiny House Regulations Matters?
Understanding NSW tiny house regulations before purchase is crucial for several reasons:
- Legality: Tiny houses can fall under different categories depending on their size, construction, and intended use. Complying with these laws avoids permit and fines.
- Placement: Regulations specify where you can legally place your tiny house. Some areas prohibit them on vacant land or have setback restrictions.
- Living Conditions: Tiny home rules cover essentials like plumbing and electrical standards for a safe living environment.
- Long-Term Use: Tiny house regulations affect waste disposal, utilities, and other long-term considerations for permanent residency.
Tiny homes on wheels are typically classified as caravans by local governments because of their mobile nature. As a result, they are often subject to local law restrictions regarding the duration a person can ‘live’ in a caravan. The development of local laws governing ‘camping’ or living in a ‘caravan’ varies.

NSW Local Government Regulation 2021: When Council Approval is Not Required
Under the Local Government (Manufactured Home Estates, Caravan Parks, Camping Grounds and Moveable Dwellings) Regulation 2021, Council approval isn’t required for:
- Two Caravans or Tents: Occupancy is limited to a maximum of 2 consecutive days and a total of 60 days within a 12-month period.
- One Caravan on Owner-Occupied Land: Solely for the owner or household members, maintained in a safe and healthy condition.
- Caravan on Pastoral or Agricultural Land: Farm workers can live in it seasonally if they work on the land.
- Moveable Dwelling or Associated Structure for Natural Disaster Displacement: You must keep the dwelling in a safe and healthy condition and remove it within 2 years of installation. Local council policies may allow for a longer period.
In addition, complaints from neighbors can lead to quick action or removal of a tiny house, posing residency challenges.
Tiny House Placement Rules in NSW:
In most cases, private placements of tiny houses do not require a Development Application (DA) under specific conditions, as long as RMS registers them as trailers.
- You must not park your tiny house too close to a neighbor’s fence.
- Avoid parking your tiny house on an easement.
- Do not obstruct a neighbor’s view.
- Apart from council regulations, suburban developments likely prohibit placing a tiny house on vacant land.
Tiny House Size and Weight Requirements in NSW:
- Length: 12,200mm max, including drawbar and rear protrusions.
- Width: 2,500mm max, including fixtures except lamps.
- Height: 4,300mm max, from road to highest point.
- Weight: ≤ 4,500kg follow Australian Design Rules (ADRs).

Total Length:
The length is the longitudinal measurement between the furthest front and rear points of the trailer. The total length of a trailer includes the length of the drawbar and coupling, as well as any rear protrusions such as a spare wheel or rack.

Total Width:
The total width is the maximum measurement of the vehicle across its body. This includes wheel guards, side-mounted spare wheels, side-mounted racks, and awnings. It does not include lamps required for compliance, permanently affixed load restraint devices, or tire pressure and inflation devices.

Total Height:
The total height measures from the road surface to the highest point of the trailer.
Total Weight:
Under the Road Vehicle Standards legislation, trailers with an aggregate trailer mass of 4.5 tonnes or less are expected to comply with the applicable Australian Design Rules (ADRs). However, not all trailers in this category will need to meet the same ADRs or ADR requirements, which may change over time. The Department of Infrastructure, Transport, Regional Development, Communications and the Arts publishes an applicability table for trailers, detailing when ADRs become applicable for each trailer category. You can find this table on the department’s website.
In summary, understanding NSW tiny house regulations ensures legal compliance and smooth integration into local communities. By following these guidelines, potential owners can navigate legal requirements and enjoy the benefits of tiny home living in NSW.
