Bangkok Rental Checklist: 47 Things to Inspect Before Signing
You’ve found a condo that looks perfect online. Great views, modern finishes, reasonable rent. The agent is pushing you to sign quickly. “Another tenant is interested.” Sound familiar?
The viewing you’re given is designed to sell, not to inform. Agents work for the landlord. Their incentive is closing the deal, not pointing out the AC that’s one monsoon season from failure or the water stains hidden behind that oversized wardrobe.
We built this checklist from real mistakes made over 8+ years renting in Thailand. More lost deposits than we’d like to admit. These are the 47 items our inspectors check before any client signs a lease.
What the full checklist covers
Our 47-item checklist is organized into 8 categories:
1. Before the viewing (5 items)
The inspection starts before you walk through the door. Research the building’s reputation, check earthquake inspection status (critical after the March 2025 Myanmar earthquake), and verify lease terms before wasting time on a viewing.
2. Building & common areas (8 items)
Lobby, elevators, security desk, parking. These tell you how the building is managed. If common areas show deferred maintenance, expect the same attitude toward your unit.
3. Structural & safety (7 items)
Wall cracks, ceiling water stains, floor leveling, window seals. Bangkok’s combination of rapid construction, tropical climate, and seismic activity creates problems most foreigners don’t anticipate.
4. Plumbing & water (6 items)
Water problems are the most common and most expensive issues in Bangkok rentals. Low pressure, slow drains, hidden leaks — in this humidity, any of those become mold problems within weeks.
5. Electrical & AC (8 items)
AC failures in Bangkok aren’t just uncomfortable — they’re health risks. The checklist covers circuit panels, outlet testing, cooling performance, and AC drainage, which causes most indoor flooding in Bangkok condos.
6. Kitchen & appliances (5 items)
Kitchen issues attract pests faster than anything else. Refrigerator seals, exhaust hood function, cabinet condition, pest entry points — all need checking.
7. Bathroom (4 items)
Bathrooms combine water, humidity, and poor ventilation — perfect conditions for mold. Exhaust fans, drainage, and silicone seals all need inspection.
8. Climate-specific (4 items)
Window seal integrity, hidden areas behind furniture, closet ventilation, exterior wall temperature. These issues develop invisibly and compound quickly in Bangkok’s 70-80% humidity.
A few examples from the full checklist
Here’s a sample of what you’ll find:
Before viewing: Ask about the landlord’s responsiveness. How are maintenance requests handled? Is there an online system? A LINE group? When your AC breaks at 2 AM in April, how you reach someone matters more than you think.
Building: Check if the emergency stairwell doors actually open. A 2024 fire at a hotel in Surat Thani killed three people. Blocked exits and missing equipment were cited.
Structural: After the March 2025 earthquake, thousands of Bangkok buildings reported new cracks. Cracks wider than 3mm or diagonal “staircase” patterns suggest structural movement.
Plumbing: Run hot water in all locations. Electric water heaters have an 8-10 year lifespan. An old unit can fail spectacularly, or it can just quietly stop producing hot water mid-tenancy.
AC: Check the drain line exit point. Clogged AC drains are the single most common cause of indoor flooding in Bangkok condos. One blockage can destroy electronics, furniture, and flooring in a single afternoon.
Kitchen: Open all cabinets and look for pest evidence: droppings, egg casings, dead insects. If you find any of those, assume active infestation.
Bathroom: Turn on the exhaust fan and hold a tissue near it. It should get sucked toward the vent. No ventilation means mold within weeks.
Climate: If possible, move furniture away from walls. Agents position furniture to hide problems. That wardrobe against the wall? It might be covering water damage, mold, or pest evidence.

Why professional inspections matter
This checklist covers what you can see. Professional inspectors find what you can’t.
Our inspectors are Thai property owners themselves. They’ve fixed these problems in their own buildings and know where issues hide. They speak English and communicate with building management in Thai, closing the language gap that leaves most expats guessing.
We don’t take referral fees from landlords or agencies. We find problems before you sign. If our inspection convinces you to walk away from a unit, we’ve done our job.
What you get:
- Visual inspection of all 47+ checklist items
- Photo documentation of every defect
- English PDF report within 24-48 hours
- Defect checklist aligned with Thailand’s 2025 documentation requirements
- Direct communication via WhatsApp, Telegram, or Messenger
Cost: ฿5,900-8,900 depending on unit size. About 10-20% of one month’s rent for quality units.
Ready for professional eyes?
Doing your own inspection beats signing blind. But there’s no substitute for inspectors who know where Bangkok landlords hide problems.
