Building Report Sanity Check
Upload a residential building inspection report. The Sanity Check verifies the inspector's LBP and NZIBI credentials, compares the report structure against NZS 4306:2005 scope and methodology, flags conclusions drawn from inaccessible areas, and identifies the common patterns of overreach (interior decorating as a defect, replacement recommendations for cosmetic items, misrepresented safety systems).
What it does
The NZ residential building inspection industry is unregulated — see NZS 4306:2005 for the voluntary standard, and The building inspection report: what NZS 4306 requires for the 12 red flags we watch for. The Sanity Check runs those checks automatically.
Inputs
- The building inspection report (PDF).
- The inspector's name and company (optional — will also be extracted from the report).
Outputs
Inspector credentials
- Licensed Building Practitioner status check against the LBP register.
- NZIBI membership check.
- Professional Indemnity Insurance status where publicly verifiable.
Structure and scope
- Presence of required NZS 4306 sections (grounds, structure, exterior, roofs, plumbing, electrical, interior, insulation/ventilation).
- Identified access limitations and whether conclusions respect those limitations.
- Scope creep flags: interior decorating, mechanical services, pest assessment, structural engineering, asbestos quantification (all outside NZS 4306 scope).
Red flags
- Conclusions drawn about inaccessible areas ("no underfloor insulation" where subfloor access is noted as limited).
- Misrepresentation of safety systems (RCD tripping on test described as a fault).
- Replacement recommendations for items the photographs show as cosmetic.
- Era-generic statements presented as property-specific findings.
- Repetitive findings across rooms that inflate without adding content.
- Photographs that appear to depict personal belongings or private living spaces.
Proportionality
- Count of building-relevant findings per page (high ratio = substance; low ratio = padding).
- Match between defect severity and recommended remediation.
What the tool does not do
- It does not assess whether specific physical findings are accurate. That requires a physical re-inspection.
- It does not replace reading the report. The Sanity Check surfaces patterns; human judgement interprets them.
- It does not determine legal liability. Where the report has material defects, CGA s.28 and FTA s.9 frameworks are the legal paths.
