How Long Does It Take to Build a Duplex and Get Permits?
Planning a duplex? Here’s what to expect on timing.
For most kit home duplex projects, construction typically takes around 6 months, assuming good site access and smooth coordination of trades.
However, the permit process can take significantly longer—anywhere from 8 to 12 months. This is due to council requirements, detailed checks, and potential requests for further information. Timeframes vary by location, so it’s best to contact your local council early and be prepared for possible delays.
