Permissible with consent vs without consent. Two phrases that sound alike and mean different things.
With consent you need a DA. Without consent you just need to comply. Many uses sit at the boundary, and the boundary moves with each LEP update.
When you read a Local Environmental Plan or Planning Scheme, every land use falls into one of three buckets:
- Permissible without consent (you can do it, no DA required)
- Permissible with consent (you need a Development Application)
- Prohibited (you cannot do it at all)
The three buckets sound clear. They are not always clear in application. This post unpacks the three, with specific examples of how the boundary between them affects what you can actually do on a lot.
Permissible without consent (the smallest bucket)
Land uses that are explicitly permitted on the lot without any council application. The list is short and conservative.
Typical examples in an R2 zone:
- Single dwelling house (the existing dwelling, undisturbed)
- Home occupation (limited business activity within an existing dwelling, no signage, no visible impact)
- Internal alterations to an existing dwelling (not structural or affecting facade)
- Boundary fencing under specified height
- Maintenance and repair of an existing structure
These are activities the council has decided do not warrant individual assessment because the impact is predictable and minor.
Permissible with consent (the largest bucket)
Land uses that are permitted only with a Development Application granted by council. The DA assesses the specific proposal against the planning controls and either approves, approves with conditions, or refuses.
Typical examples in an R2 zone:
- New dwelling construction (replacement or new)
- Major extensions or renovations
- Dual occupancy (in zones that permit it)
- Secondary dwelling / granny flat (typically under the affordable rental SEPP rather than a full DA)
- Swimming pool over a certain depth
- Major outbuildings or detached studios
- Change of use (e.g. converting a residential dwelling to a home business with external impact)
The DA process can take anywhere from 6 weeks (simple, well-prepared, undisputed) to 24+ weeks (complex, contested, or requiring multiple consultations). Cost: $5,000-30,000 depending on complexity.
Prohibited
Land uses that cannot occur on the lot regardless of any application. The prohibition is absolute.
Typical examples in an R2 zone:
- Industrial uses
- Intensive livestock
- Mining and extraction
- Heavy commercial uses
- Hostels in some councils
- Backpacker accommodation in some councils
- Brothels in most councils
Prohibited uses cannot be approved through DA. The only way to change a prohibited use to permitted is via a Planning Proposal to amend the LEP, which takes 12-24 months and requires state government concurrence.
The boundary cases
Three categories of use sit at the boundary between buckets and are the source of most planning disputes:
Category 1: home-based business
A home-based business is permissible without consent if it meets the "home occupation" definition: no employees beyond family, no signage visible from the street, no client visits beyond a small threshold, no use of more than a defined area of the dwelling.
If the business exceeds these limits, it becomes "home business" or "home industry" which is permissible with consent (DA required). If it exceeds those limits, it becomes a commercial use which is prohibited in residential zones.
The boundary depends on:
- Number of employees
- Client visits per day
- Signage
- Floor area used
- Hours of operation
- Visible impact (noise, traffic, parking)
A doctor seeing 4 patients a day from a converted ground-floor room may sit on the boundary between home occupation, home business, or a fully consented medical practice. Different councils, different answers.
Category 2: short-term rental accommodation
In 2026, short-term rental (Airbnb-style) sits in an evolving regulatory space. NSW has introduced state-wide rules limiting STR in non-host-occupied properties to 180 days per year in Greater Sydney. VIC has similar restrictions in tourism areas. QLD is council-dependent.
Whether STR is "use of dwelling" (without consent), "tourist and visitor accommodation" (with consent), or "prohibited" depends on:
- The property type (entire dwelling vs single room)
- The frequency (occasional vs continuous)
- The duration of individual stays
- Council-specific rules
The boundary moves regularly. What was permissible last year may require consent this year.
Category 3: secondary dwelling vs separate dwelling
A "secondary dwelling" (granny flat) is permitted under the NSW Housing SEPP without a full DA, subject to specific conditions (max 60sqm, must share parking, max one per lot, owner-occupier required in some councils).
A "separate dwelling" is a fully independent house on the lot. It requires a full DA and typically subdivision.
Builders sometimes build "granny flats" that exceed 60sqm or operate as fully separate dwellings. They sit at the boundary between the two consent categories and are an enforcement risk.
What to do before exchange
Three habits:
Habit 1: read the LEP table of permitted uses for your zone
NSW: the LEP's land use table for the zone lists each use category as permissible without consent, with consent, or prohibited. Read it directly.
VIC: the Planning Scheme's Table 1 in each zone serves the same function.
QLD: the City Plan / Planning Scheme's land use tables.
Habit 2: confirm the use category for your intended activity
If you plan to use the property in a specific way (home business, STR, granny flat, secondary dwelling), identify the use category in the LEP. Confirm it is permissible (with or without consent) in your zone.
Habit 3: read the conditions on each category
Many categories have specific conditions that must be met for the permissibility to apply. Without meeting the conditions, the use falls into a different bucket.
The 5 minutes spent reading the LEP table is more useful than the 20 minutes spent reading the listing description.
The 60-second check
For any property and any intended use:
- Confirm the zone from the LEP
- Find the land use table for the zone
- Find your intended use category
- Read whether it is without consent, with consent, or prohibited
- If with consent, estimate the DA timeline and cost
If the intended use is prohibited, the property is wrong for your purpose. If it is with consent, you have a DA pathway to plan. If without consent, you can proceed.
The three permissibility buckets are simple in concept and contested in application. Reading them carefully tells you which DA you do or do not need. Misreading them is the source of most "we did not know that needed council approval" disputes.
