    Hi Everyone

    I searched the net and this forum to no avail…

    i understand what R17.5 and R30 mean with respect to the minimum block size you can build a dwelling on, but I cant for the life of me find anywhere what a property zoned R17.5/R30 means? Im looking at a block just under 1000m2, so if the R17.5 restrictions are there, then it is no good to me. If the R30 is applicable, then it is a very different story. How can you find out?

    The land is advertised as R20 by the REA, so thats different again! I got the 17.5/30 from the council webpage

    cheers

    Kurt

    HiI guess your best option is to speak with the council and do try to get the advice in writing before buying. I have been through the scenario of one telling you something and another saying something else!Toni

    Hi There,

    My specialty – Residential Design Codes (Western Australia)..

    Two Codes like R17.5/R30 is called a split coding.. it means that the property is firstly R17.5 zoning and if you want to get the higher density of R30 then you need to meet certain Council criteria.

    R 17.5 has a minimum average lot size of 571sqm so you would need 1142m2 before you can be permitted to subdivide.R30 has a minimum average of 300m2 so you would need minimum of 600m2 to subdivide into two.  As the block is 1000m2 you can get 3 lots from it.

    The Local Government Town Planning Schemes have the details regarding the criteria or they may have a policies on their website.  You need to talk to a Town Planner (preferably a senior one) and ask what the criteria is for the higher density and if they can forward you a copy of them.  usually it is only connection to main sewerage but other council have other more detailed requirements.

    Ktastrphe link basically means that the bonus under the R-Codes for R20 (min. avg 500m2) has no time limit any longer.  The bonus clause means that a R20 lot can have a min. avge 450m2 (but only as a grouped dwelling – common property) so if you have a lot that is 900m2 in size and zoned R20 prior to 2 October 2002 you can get two group dwellings lots from it

    If you have any other questions you are welcome to jump on my forum at http://www.plancheck.com.au

    I hope this helps…

    Cheers

    Hi Helen,

    Just for information sake, each time i have dealt with a split zoning the council criteria has simply been a sewer connection. I wonder what other council criteria you have come across and give me some examples?

    Cheers

    Hi Lockymac,

    PlanCheck is right most councils require only sewerage however, i know through experience that  councils such as City of Fremantle, Town of Bassendean and some parts of Wanneroo District to name a few have other requirements.

    Cheers

    Thanks for the replies. I viewed the property i was talking about and it was closer to a main road than i thought, and had a massive gradient on the land. The house on the block was also uninhabitable. Looks like way too much work (and money) to me.

    Hi, for detail info on R17.5/R30 as well as other R-codes for WA, there’s an article here written about it: R-Zoning Codes for Western Australia – What Does it Mean?
