The defect liability period is compulsory with all newly built homes. This can be either 4-month or 6-month after handover depending on what has been contractually agreed with your builder.
The onus is on the new homeowner to contact the builder with a defect list for which the builder has to make good providing the defect has not been caused due to misuse or neglect.
The inspection report will identify all maintenance issues which can be sent to your builder.
