Home inspector
Kind: Who diagnoses the building before work begins
Tag: pre-renovation assessment, risk identification, existing conditions, diagnostic
Role in the system
The home inspector performs a visual, non-invasive assessment of a property’s condition before renovation begins. The goal is diagnostic and advisory: identify material defects, safety hazards, structural issues, and potential code violations that will shape the project’s scope, budget, and contingency. The inspector recommends further evaluation by specialists (structural engineers, environmental consultants) when issues are found but does not perform destructive testing or provide engineering services.
This role is fundamentally different from the municipal code inspector (City county and state authorities (AHJ)), whose function is regulatory — verifying compliance at specific construction stages. The pre-renovation inspector serves the homeowner and contractor as a risk-identification tool.
Delivery-model nuance
- Renovation: Core role. The pre-renovation inspection is the first line of defense against concealed conditions and establishes the baseline for contingency planning.
- New construction: No equivalent role. New-build inspections are regulatory (municipal) or contractual (private QA/QC against specifications), not diagnostic.
