I've been having quite a few conversations around this one. For those in NSW, there is more to subdivision than just the Minimum Lot Size Maps listed in your LEP. For example, I am currently dealing with someone who was looking at a granny flat because they couldn't do a subdivision as they couldn't meet the 700sqm minimum lot size for both blocks of land. Hidden deep within the Standard Instrument LEP is an option clause - some Councils have put it in. Others haven't. In this particular instance the lovely, hidden clause that doesn't appear on a Section 149 Certificate allowed for a minimum lot size of 400sqm for a new lot (instead of 700sqm) if the subdivision application was lodged at the same time as the dwelling design. This allows for Council to assess the potential impacts of the dwelling alongside the subdivision. Result for the client, as they were able to get a new, 4 bedroom torrens title house, that they could rent (at $450 pw according to the estate agent), or sell (at $540k), instead of just a granny flat in the backyard that would only give them a little bit extra in rent a week (around $280). So, always do a little bit more digging in to what you can and can't do - there are lesser known clauses that can be incredible beneficial in adding value to your investment property.
