Older Home Inspection Checklist
Older homes can combine original construction, repairs, additions, and multiple generations of systems. Age alone does not establish condition, but it changes the questions worth asking.
Practical checklist
- Identify additions, converted spaces, structural changes, and visible differences in materials or workmanship.
- Document service panels, wiring types, plumbing materials, heating systems, chimneys, and fuel storage.
- Look for drainage, foundation movement, moisture, wood deterioration, and ventilation patterns.
- Ask about roof layers, windows, insulation, sewer or septic, and prior water events.
- Treat suspect lead or asbestos-containing materials as undetermined until evaluated safely.
Questions worth asking
- Which systems are original, replaced, abandoned, or near an expected maintenance decision?
- Are permits and professional records available for alterations?
- Should an engineer, electrician, plumber, chimney professional, sewer contractor, or environmental professional be involved?
- Which materials must not be disturbed before testing?
- What insurance or financing questions should be resolved early?
