Hi Guys I have a 410sqm block of land in Sydney and im looking to build a house and granny flat. My understanding is that a block must be above 450sqm to build a detached granny flat however there are some comments on the net that you can build an attached granny flat if the block is under 450sqm. Does anyone know the rules around this?
from my understanding of the code the 450m2 requirement is for detatched granny flats attached has no min lot size requirement
Regulations vary from council to council so by speaking with council or a town planner you should be able to obtain specific advice
Some councils may accept even semi detached duplexes on 400sqm sites. I have already approved a few of these, you can then subdivide and sell them separately. Where is your land located? The catch for CDC granny flats on small lots is that clause 23(2)(d) of the housing code says that the development must "involve no external alterations to the principal dwelling other than the provision of an additional entrance", so you either have to: a) have a house that is sufficiently large to allow conversion of part of it into a granny flat; or b) approve an extension for the house first, then prepare a separate application for the party wall and new entrance to the granny flat; or c) find a certifier who is happy to approve both applications from alternative (B) in one go.
I have read that there is no minimum lot requirement. Fabs - the block is currently just vacant land so does that mean we can't do the house and granny?
Declan, please replace item (b) in my previous post with: "b) approve/build a large new house first, then prepare a separate application for the party wall and new entrance to the granny flat; or" Because your land is vacant, I would reinforce my recommendation to review council's or CDC controls for duplexes or semi detached dwellings.
@Fabs thats what im trying to understand - does CDC allow for this? This seems to say there is no minimum: New NSW SEPP Legislation Live Now! - Granny Flat News
@Declan That post was from February 2014, not sure if the rules are still the same. In any case I recommend that you discuss this with a certifier.
