Inspection scheme age thresholds

• Not yet the 30-year age threshold of the Mandatory Building Inspection Scheme (domestic buildings of 3 storeys or fewer are exempt); BD may serve an inspection notice.
• Reached the 10-year age threshold of the Mandatory Window Inspection Scheme (same exemption).

Age counts from the occupation permit date; BD selects buildings for notices by risk. See BD: MBIS.
