BTO Defect Check Singapore 2026: Complete Inspection Checklist and Cost Guide

BTO Defect Check Singapore 2026: Why This Step Matters More Than Most Homeowners Realise For most Singaporean households, collecting the keys to a new Build-To-Order (BTO) flat is one of the biggest milestones in life. After years of waiting through balloting, loan approvals and construction updates, the excitement of finally holding those keys can make it tempting to skip straight to planning your renovation. However, before a single wall is hacked or a single tile is laid, there is a critical step that experienced homeowners, renovation contractors and property agents alike will tell you never to skip: the bto defect check .
