Second-Hand House in Chiang Mai 2026 — What to Inspect Before Buying?

Buying a second-hand house in Chiang Mai requires thorough inspection before committing. This article provides a complete checklist from our 20+ years of local real estate experience.

1. Structural Inspection

What to check
- Cracks on walls, ceilings, and floors (minor hairline cracks are normal — large cracks are concerning)
- Strength of columns and beams
- Roof condition — check for leaks and water damage
- Flooring condition — check for warping, sinking, or loose tiles
- Damp walls or water stain marks

2. Electrical System

What to check
- Main switchboard and wiring condition
- All power sockets and switches — test that each works
- Whether the circuit capacity is sufficient for typical usage
- Grounding (especially in bathrooms and kitchen)
- Age of the electrical system (over 20 years old should be replaced)

3. Plumbing and Drainage

What to check
- Water pressure in all bathrooms and kitchen
- Drainage in sink, bathrooms, and floor drains
- Waste pipes and septic system
- Water tank and pump condition (if applicable)
- Water color and odor

4. Air Conditioning

What to check
- Number and size of units relative to room area
- Age and maintenance history
- Test operation and cooling capacity
- Drain pipe condition

5. Surroundings and Environment

What to check
- Flood history of the area (ask neighbors or check online)
- Road and access condition
- Noise from roads, factories, or nearby venues
- Future construction projects in the area
- Neighborhood safety

6. Chiang Mai-Specific Checks

Special risks in Chiang Mai
- Termites: High termite risk in Chiang Mai — inspect every part of the house
- Mold: High humidity during rainy season — check walls and ceilings
- Land subsidence: Some suburban areas have soil settling issues
- Air pollution: Houses without air filtration may have problems during March-April haze season

Should You Hire a Professional Building Inspector?

Highly recommended. Professional building inspection costs approximately THB 3,000-10,000 but can save many times that amount if major problems are discovered before purchase.
