Tiny House Approval in NSW: How to Get Your Tiny Home Approved (Without Guessing)
Tiny homes are booming across New South Wales — backyard studios, compact cabins, granny-flat-style tiny houses, and the ever-popular tiny house on wheels (THOW).

“Tiny home” isn’t a single planning category in NSW.
Your approval pathway depends on what your tiny home legally is (and how you plan to use it): a secondary dwelling, a dwelling house, or a moveable dwelling (often treated like a caravan/campervan in the regulations).
This guide explains the NSW-wide approval pathways and requirements — with the practical “what do I actually do next?” detail homeowners want.

Important: This is general NSW information (not legal advice). Always check your site constraints (zoning, bushfire/flood, servicing, heritage) and confirm your exact pathway with your council and/or a registered certifier.
Tiny home approvals in NSW: the 15‑second decision tree
Start here:
1) Is it permanently sited (fixed, footings, plumbed like a house)?
You’re usually in normal building + planning territory (DA or CDC), just like any other home — even if it’s small.
2) Is it a second dwelling in the backyard (kitchen/bathroom + self-contained)?
That’s typically a secondary dwelling (granny flat) under NSW rules.
3) Is it on a trailer / “THOW” / relocatable style?
You may be treated as a moveable dwelling / caravan / campervan for certain council “installation approval” rules — but that does not automatically mean “no approvals ever.”

The 3 approval “layers” that trip people up in NSW
Most NSW tiny home projects touch some combination of:
-
Planning approval pathwayCDC (Complying Development Certificate) = fast-track if you meet strict standards
-
DA (Development Application) = council assessment if you don’t meet CDC or the site is complex
-
Building compliance Even when you’re doing CDC/DA, works generally need to comply with the Building Code (NCC/BCA) and be certified.
-
Additional council approvals (often “Section 68 approvals”) These are separate approvals for certain activities — including installing a moveable dwelling and onsite sewage systems.

Pathway A: A permanent tiny house (fixed) in NSW
If your tiny home is fixed to land and built like a small house, approvals generally follow the same logic as any dwelling:
- Tiny home as the main dwelling on a vacant lot → assessed as a dwelling house (CDC if it meets Codes SEPP standards, otherwise DA).
- Tiny home as an extra dwelling behind/near an existing home → usually a secondary dwelling (granny flat) under the Housing SEPP.
Secondary dwelling (granny flat) basics in NSW (statewide)
NSW planning rules define a secondary dwelling (granny flat) as a self-contained dwelling located within, attached to, or separate from another dwelling on the same site.
Statewide rules also make clear that:
- Secondary dwellings are permitted in R1–R5 residential zones (and may also be permitted in other zones depending on your LEP).
- You generally can’t subdivide the lot to split off the granny flat.
- The “end state” is typically one principal dwelling + one secondary dwelling on the site.
CDC for a secondary dwelling in NSW: the common “fast track” route
A secondary dwelling can be approved as complying development (CDC) if it meets the Housing SEPP requirements and development standards (including Schedule 1).
Key NSW-wide points to understand:
- Maximum size (common rule): secondary dwelling floor area is generally capped at 60 m² (unless another instrument allows more).
- Minimum lot size (common CDC trigger): for an attached or detached secondary dwelling CDC, the lot must generally be at least 450 m².
- Zone nuance: the CDC provisions for secondary dwellings have specific rules (for example, the Housing SEPP’s CDC division applies on land in a residential zone other than R5).
- Building a house + granny flat together: NSW allows a principal dwelling + secondary dwelling to be approved together under a single CDC when each component meets its pathway requirements.
- Parking: NSW Housing SEPP guidance indicates it doesn’t require additional parking for a secondary dwelling (but you still need to avoid removing required existing parking in some situations). If you can’t meet all CDC standards, you can still do a DA (and council assesses the proposal on its merits).
Pathway B: Tiny House on Wheels (THOW) in NSW
THOW approvals in NSW are where most misinformation lives.
A THOW is often marketed as “not a building” — but in practice, councils look at:
- what it is physically (often a caravan/campervan/moveable dwelling), and
- how it’s used (short-term, long-term habitation, rental accommodation, worker housing, etc.).
What the NSW moveable dwelling rules actually say (the core exemptions)
NSW has specific statewide exemptions where council approval is not required for the installation of certain caravans/tents on land outside caravan parks/camping grounds.
Under the NSW Local Government regulation:
Council approval is not required for installation of:
- 2 caravans or tents if they are not occupied for more than 2 consecutive days, and not more than 60 days in a 12‑month period
- 1 caravan on land occupied by the owner in connection with the owner’s dwelling house if it’s used for habitation only by the owner or members of the owner’s household and maintained safely
- A caravan on pastoral/agricultural land if it’s occupied seasonally by workers employed in pastoral/agricultural operations
- A moveable dwelling for someone displaced by a natural disaster (subject to conditions and time limits, including “removed within 2 years” unless a longer period is specified by the relevant local approvals policy) Also, the regulation clarifies “caravan includes campervan” for that exemption section.
What this means in plain English
- There are statewide situations where a THOW/caravan-style tiny home can be on land without that specific council “installation approval.”
- But those exemptions are narrow and conditional — and they’re about one type of council approval.
“Caravan” vs “campervan”: why it matters for THOWs
The same NSW regulation defines:
- campervan as a moveable dwelling (other than a caravan) designed to be capable of being registered as a motor vehicle (and includes a camper trailer)
- caravan as a moveable dwelling designed to be capable of being registered as a trailer (excluding a camper trailer) Many THOWs are built to sit in that “caravan/trailer” concept — but whether it’s actually registrable (and used as such) is a separate practical issue.
When you do need council approval for a THOW / moveable dwelling
If you don’t fit the exemption conditions, council approval may be required to install a moveable dwelling — and applications generally need plans/specifications and a site plan (among other things).
Also, councils can have a local approvals policy referenced in the regulation (important for special cases like longer disaster accommodation periods).
DA vs CDC in NSW (and why “tiny” doesn’t automatically mean “easy”)
Complying Development Certificate (CDC)
CDC is a fast-tracked approval route for straightforward development if you meet the exact standards in the relevant NSW policies (often the Codes SEPP, and for secondary dwellings, Housing SEPP + Schedule standards).
The NSW Planning Portal explains CDC as:
- a fast-track process combining planning + construction approval
- determined by council or an accredited certifier
- often used for things like a new home or a granny flat
Development Application (DA)
If you can’t meet CDC standards — or your site has constraints (heritage, bushfire, flooding, unusual access, servicing limitations, zoning issues) — you’re typically in DA territory.
BASIX + sustainability requirements (yes, tiny homes too)
If your tiny home is a new residential building proposal (e.g., new house, dual occupancy, multi-unit), NSW generally requires you to include a BASIX Certificate with your proposal.
The NSW Planning Portal is explicit that you obtain the BASIX Certificate to submit with your DA or CDC, and then attach it to your development plans when lodging.
Section 68 approvals: the “extra” approvals many people miss
Even with DA or CDC underway, you may also need Section 68 approvals (Local Government Act) for certain activities.
The NSW Planning Portal notes these approvals are often in addition to standard DA requirements and can include:
- installing a manufactured home / moveable dwelling
- sewerage work / stormwater drainage work
- installing/altering a septic tank or waste treatment device
- operating an onsite sewage system
Onsite sewage / septic for tiny homes (especially rural/off-grid)
If your tiny home isn’t connected to sewer, the NSW Office of Local Government explains:
- you may need two council approvals: one to install the system, and one to operate it This is a huge practical issue for tiny homes on acreage and rural lots: a “cute compact home” still creates real wastewater that must be managed legally.
If you want to Airbnb your tiny home in NSW (hosted vs non-hosted STRA)
If your tiny home will be used for short stays, you need to think about Short‑Term Rental Accommodation (STRA).
NSW planning guidance defines STRA in the Housing SEPP framework and distinguishes:
- hosted STRA (host resides on the premises)
- non-hosted STRA (host does not reside on the premises) NSW planning guidance also notes that if you live on a property with a granny flat, you can rent out the granny flat as hosted STRA year-round (subject to the broader STRA framework).
(If STRA is your plan, don’t treat it as an afterthought — it can change how councils view permissibility, compliance, and neighbour impacts.)
The most common NSW tiny home approval mistakes (and how to avoid them)
Mistake 1: “It’s under 60m² so it’s exempt”
Exempt development in NSW is for minor works — a habitable dwelling is not “exempt” just because it’s small. CDC or DA still applies depending on your scenario.
Mistake 2: “It’s on wheels so council can’t touch it”
NSW has clear rules about when council approval is or isn’t required for installation of caravans/moveable dwellings — and the exemptions are specific.
Mistake 3: Forgetting Section 68 approvals (especially sewage)
Section 68 approvals commonly cover moveable dwellings and onsite sewage management activities.
Mistake 4: Doing the build first, then chasing approvals
If you want a clean approval pathway (and avoid compliance action), do a quick feasibility first: zoning, lot size, bushfire/flood/heritage, servicing, access, and your intended use.
How Planland can help with NSW tiny home approvals
If you want to move fast and stay compliant, Planland can help you:
- identify whether your tiny home is best treated as a secondary dwelling, dwelling house, or moveable dwelling pathway
- map the likely CDC vs DA route (and the hidden “extras” like Section 68)
- coordinate the core documentation (site plan, design plans, structural plans/specs, BASIX, etc.) that certifiers/councils typically require
- flag early “red zones” (servicing limitations, bushfire/flood constraints, access issues) If your project is basically “a granny flat, but tiny,” you may also want to read Planland’s existing NSW guide on secondary dwellings/granny flats (it dovetails neatly with this tiny home topic).
