10 Due-Diligence Questions Before Buying Elderly Housing in Bangkok

Many Bangkok projects advertise Smart Home Friendly or Wellness Living — but after moving in, residents discover the juristic office prohibits wall drilling, or internet bandwidth is too low for cloud-based sensors. These 10 questions filter genuinely ready projects from marketing.

Question 1: What is the Juristic Office’s IoT Modification Policy?

Green Flag: Written policy permitting wall drilling for grab rails and sensors (with permit process) Red Flag: Blanket prohibition on drilling, or no clear policy exists Why it matters: Grab rails and ceiling mmWave both require drilling — if prohibited, they cannot be installed

Question 2: Internet Infrastructure — Is Fiber Reaching the Unit?

Green Flag: Fiber-to-Unit (FTTU) at ≥100 Mbps symmetrical Red Flag: ADSL or shared Fiber-to-Building (shared bandwidth below 30 Mbps during peak hours) Why it matters: Cloud-based mmWave and LINE alerts require sustained ≥5 Mbps uplink — shared connections lag in emergencies

Question 3: What is the Ceiling Height?

Green Flag: ≥2.7 metres in all rooms Red Flag: 2.4 metres in bedrooms — restricts ceiling mmWave, requires wall-mount models How to verify: Request architectural plans showing Finished Ceiling Height (not Slab-to-Slab)

Question 4: What Universal Design Features Actually Exist Inside the Unit?

Green Flag: Bathroom door ≥80 cm clear, no threshold, bathroom wall blocking pre-installed for grab rails Red Flag: Universal design only in common areas; standard units not designed for elderly needs Follow-up: Request the bathroom Blocking Plan to confirm wall can support ≥120 kg grab rail load

Question 5: Is There Backup Power?

Green Flag: Central UPS covering elevator and common areas for ≥4 hours Red Flag: No backup power — power outage means elevator stops and Smart System goes offline Follow-up: Ask whether Panic Button sends alerts during power outage (battery-powered vs AC-powered)

Question 6: Is There a 24-Hour Call Centre or Nurse Call?

Green Flag: Juristic office answers 24 hours with clear 1669 escalation procedure Red Flag: Only security guards present — not trained first responders

Question 7: What is the Smart System Maintenance SLA?

Green Flag: Contract specifies ≤4-hour response time for safety-critical device failures Red Flag: No SLA — if mmWave fails, wait days for a technician

Question 8: Are After-Market Smart Devices Permitted?

Green Flag: Residents may install their own chosen devices Red Flag: Project system only — locked into a single vendor

Question 9: Distance to Private Hospital?

Green Flag: ≤10 minutes by car to a private hospital (not government hospital only) Red Flag: ≥20 minutes — Golden Hour emergency timing begins from the event

Question 10: What is the Pet Policy?

Green Flag: Pets permitted — elderly pet owners show 15% better mental health and longevity outcomes (Harvard Study 2024) Red Flag: No pets of any kind — a significant quality-of-life restriction for solitary elderly

Questions & answers

How does a juristic no-drilling policy affect elderly Smart Home?
It prevents installing grab rails rated ≥120 kg, ceiling mmWave, or embedded night lights. Smart Home is limited to wireless portable devices, significantly restricting safety options.
How do I verify ceiling height before purchase?
Request Finished Ceiling Height from architectural plans — not Slab-to-Slab which is higher. If Finished Ceiling is below 2.5 metres, only wall-mounted mmWave models can be used.
How close should a hospital be for elderly residents?
Within 10 minutes by car to a private hospital with 24-hour emergency department. For high-risk elderly, ≥20 minutes is considered too far for cardiac or neurological emergencies.
