Before owner builder home warranty insurance can be organised, a post-construction owner-builder defects inspection and report is required by the insurer of the completed work, to identify any building defects.
A defects report is issued after an owner-builder defects inspection has been carried out by a building consultant who is acceptable to the insurer, and who has current Professional Indemnity Insurance.
You can sell with those defects identified, or have them fixed and organise a follow-up inspection so that a ‘defects free’ report can be issued.
