BRISBANE GRANNY FLAT APPROVAL PROCESS

Tiny Blox is revolutionising the Australian tiny house movement with DIY prefabricated kit set style pre-designed tiny home kits shipped directly to your door. 

An extension to an existing dwelling house in a residential zone for a granny flat is referred to in the City Plan as a secondary dwelling. It can be a maximum of 80 square metres in size. If the granny flat is for a member of your "household" (Keep reading because you can rent out rooms in your household), you don't need to get Council approval as long as you meet the accepted development, subject to requirements criteria in the Dwelling house code or Dwelling house (small lot) code.


Small lots are less than 450 square metres or for a rear lot less than 600 square metres excluding the access way.


You will need to lodge a development application if:

  • the granny flat is bigger than 80 square metres in size
  • it is more than 20 metres from the main house.

You will need a development application for a different use, a ‘dual occupancy’, if you are renting it to someone who does not form part of your "household".

BUILDING A HABITABLE GRANNY FLAT OR TINY HOME IN BRISBANE, AUSTRALIA

So you want to know the process for getting a granny flat or try home approved in BRISBANE COUNCIL.  


Put simply, if you build your Granny Flat or Tiny Home in line with the  government code then you will not require a Development Approval (DA) in Brisbane; you can simply choose one of our TINY BLOX plans and we will use our private certifier to approve the Granny Flat or TINY HOME sometimes as quickly as 20 days. This means that you can place your order for a TINY BLOX and your building materials will arrive on site very quickly (Often within 21 days).

The basic requirements are that you maintain the correct set backs from your side and rear property boundary and keep the granny flat or tiny home a reasonable distance from your existing house.

A ‘household’ is defined as an individual or a group of two or more related or unrelated people who reside in the dwelling, with the common intention to live together on a long-term basis and who make common provision for essentials for living.


A household can be:

  • one person maintaining a household
  • two or more people related by blood, marriage or adoption
  • up to five children under the age of 18 that are not related and one or two adults who have care of them
  • no more than five people that are not related.


You are permitted to rent rooms in your household to numerous individuals which means that as long as you rent your granny flat to people that are "part of the household" i.e. they help pay for electricity, water, internet etc and you don't plan to meter your granny flat separately then you qualify.

BUT How is a household defined in Brisbane City Plan 2014?

What are the setbacks from boundaries for granny flats?


Boundary setbacks for granny flats on standard sized lots* are set by the Queensland Development Code and are not included in the City Plan. Boundary setbacks for granny flats on small lots** are identified in the Dwelling house (small lot) code below:


SIDE SETBACKS

(a) 1m for habitable spaces; or

(b) 0.5m and a maximum height of 3.5m for non-habitable spaces only for a maximum length of:

  1. 15m, where located in the Low–medium density residential zone, Medium density residential zone or High density residential zone; or
  2. 9m, where in the Low density residential zone or the Character residential zone; or

(c) 0m where:

  1. matching the extent of an existing built to boundary wall on the adjoining property; or
  2. the adjoining property is 300m2 or less and in the Residential zone category other than in the Character zone precinct of the Character residential zone; or
  3. on a lot with an average width of 7.5m or less where the adjoining property is 300m2 or less and in the Residential zone category other than in the Character zone precinct of the Character residential zone and the adjoining property has no existing built to the boundary wall; or
  4. on a lot with an average width of more than 7.5m in the Low density residential zone or the Infill housing zone precinct of the Character residential zone where the registered owner of the adjoining premises does not object to a setback less than AO6(b) but only for non-habitable spaces, a maximum height of 3m and a maximum length of 9m; or

(d) located within an approved building envelope for the site to the extent of any inconsistency with (a), (b) or (c).


REAR SET BACKS


Development results in a minimum rear boundary setback that is:

(a) 6m, where on a lot with an average depth of more than 25m; or

(b) on a lot with an average depth of 25m or less:

  1. 3m, for a part of a building or structure up to 4.5m high;
  2. 4.5m, for a part of a building or structure over 4.5m high.

(c) located within an approved building envelope for the site to the extent of any inconsistency with (a) or (b).



What is the maximum site cover?

Site cover is the proportion of the site covered by buildings including the main house and the granny flat or any structure attached to the buildings and carports. It does not include structures such as gazebos or shade structures. For small lots, the City Plan requires site cover of all relevant buildings and structures on the site to be a maximum of:


50% for lots 400 m2 or more

60% for lots 300 m2 or more and less than 400 m2

70% for lots 200 m2 or more and less than 300 m2

80% for lots less than 200 m2.

Site cover restrictions for standard sized lots are set by the Queensland Development Code, which can be found on the Department of Housing and Public Works website at www.hpw.qld.gov.au and can be confirmed by a private building certifier.


Is car parking required for granny flats?

One (1) car parking space is to be provided on the site for a granny flat plus one (1) car parking space for the main dwelling house.
