Is Building Safety Act compliance required for all buildings?

No. The enhanced occupied building regime primarily applies to Higher-Risk Buildings (HRBs) under the Building Safety Act 2022.

An HRB is generally a residential building that is:

• 18 metres or more in height, or
• 7 or more storeys,
• and contains at least 2 residential units.

However, governance improvements and structured safety documentation may still be appropriate for complex non-HRB buildings where regulatory scrutiny or organisational risk exposure is high.
