This fills in the enquiry form below; nothing is sent until you submit it. Your details are handled under this site's Privacy Policy.
This lists each source's own lines as read; it is not legal advice, and it sets no price. The value that counts is the value of the work, including materials, labour and GST. Rules marked as applying to a kind of job (plumbing, electrical work, a heritage item or conservation area, a pre-1990 home, a Mine Subsidence District, a strata lot, an owner-builder, an NDIS-funded modification) apply whatever the value. The City of Newcastle lines apply inside the City of Newcastle; Lake Macquarie's own council rules are not yet sourced.
What changes a quote
Touching the structure comes first: the renovation category excludes work on a load-bearing part of the building, and structural work can take a job outside the exempt development test. Plumbing and electrical scope is second, because both are licensed at any value and electrical work carries a compliance certificate within seven days. Asbestos is third: removing more than 10 m² of non-friable asbestos, or any amount of friable asbestos, needs a licensed removalist, and 10 m² is about the wall sheeting of one small bathroom. Heritage controls are fourth: City of Newcastle says most building works in a heritage item or conservation area need development consent, and offers written confirmation for minor works including a non-original bathroom. A Mine Subsidence District address is last: structural work needs Subsidence Advisory NSW approval first, while internal work to an ensuite is already exempt.
Fees a government body sets
