Statutory Authorities & Construction Law

Frequently Answered Legal Enquiries

Deep legal clarity on building owner responsibilities under the Building Safety Act 2022.

Who is the Principal Accountable Person (PAP)?
Under Section 72, if there is only one accountable person, they are the PAP. If there are multiple accountable persons (e.g. commercial freeholder and residential head-lessee), the PAP is the person who holds a legal estate in possession of the building structure and exterior.
What is a Building Liability Order (BLO)?
Section 130 allows the High Court to make a Building Liability Order piercing the corporate veil. If an SPV developer caused a defect and dissolved or has insufficient assets, the court can hold parent companies and associated group companies jointly and severally liable.
Can the 28-day BSR call-in window be extended?
Statutorily, no. The 28-day deadline is set by secondary legislation. The BSR will only consider extensions in extraordinary, verifiable force majeure events. Having an incomplete Safety Case Report is not an acceptable ground for extension.
Does the 30-year limitation apply to commercial buildings?
No. The 30-year retrospective limitation under Section 135 applies strictly to claims under the Defective Premises Act 1972, which covers dwellings (residential premises). Commercial-only premises remain subject to standard Limitation Act periods (typically 6 or 12 years for deed contracts).
