Do you need council approval for a granny flat or secondary dwelling in Ipswich?
Whether a granny flat or secondary dwelling in Ipswich needs a development application is decided by Ipswich City Plan 2025, Version 2, which places each proposal in one of the three Planning Act 2016 categories: accepted development, code assessable or impact assessable. For an Ipswich lot the answer turns on the zone, any precinct mapped over it and the overlays that apply, so Ipswich council does not publish one blanket answer for granny flat and secondary dwelling proposals.
Casa's rules register for Ipswich City Plan 2025 records a secondary dwelling as contemplated in 20 of the 25 Ipswich zones it tracks, including Community Facilities, Conservation, Character Residential, District Centre and 16 other zones, and not in 5 others. An Ipswich granny flat that meets the scheme's size and siting requirements for its zone can often proceed on building approval alone, while one that falls outside them or picks up an overlay trigger needs a development application.
The Ipswich record gives a feel for what assessment involves: a quarter of the 18 dated granny flat and secondary dwelling decisions were made within 35 days of lodgement, and a quarter took longer than 86 days.
The zone, precinct and overlay position of one Ipswich address is what settles the pathway for a granny flat or secondary dwelling, and a free Casa block check reads all three for any Ipswich lot in seconds.

"not held" means Ipswich's register has no value for that granny flat and secondary dwelling cell, not that the scheme is silent. Height, setback and site-cover figures for Ipswich zones are held in the register but have not been checked against the scheme text, so they are not printed on this granny flat and secondary dwelling page.
