What Is a Home Inspection for Rental Properties?

A "home inspection" (building diagnostic) is a service in which a housing specialist (home inspector) objectively assesses the condition of a building's structure and equipment. While primarily used in the sale of existing homes, the fact that it can also be used for rental properties is not widely known.

With the 2018 amendment to Japan's Real Estate Brokerage Law, real estate agents are now required to disclose whether a home inspection has been conducted when explaining important matters in property sales or rentals. The regulation also applies to rental properties, and it is worthwhile to consider a home inspection before moving in, especially for high-rent or older properties.

When Home Inspections Are Useful for Rental Properties

1. Before Moving Into an Older Property

For properties 25 years or older, it is important to assess equipment deterioration, aging plumbing, and water leak risks before moving in. In particular, the following issues become difficult to address through repair negotiations if discovered after occupancy:

• •Water leak or flooding traces
• •Termite damage (for wood-frame properties)
• •Aging supply and drainage pipes, water leak risks
• •Cracks in exterior walls and roofs (for single-family rental homes)

2. Moving Into a Single-Family Rental Home

With single-family rental homes, responsibility for maintaining and managing the entire building becomes somewhat more complex. By conducting an inspection before move-in to understand the building's condition and reaching a clear agreement with the landlord on the scope of repair obligations, you can prevent future issues.

3. High-Rent Properties

For high-rent properties with monthly rent of ¥150,000 or more, paying for an inspection (¥20,000–¥50,000) may well be worthwhile.

Key Inspection Points During Property Viewings (Self-Check Version)

Even if you don't hire a professional inspector, there are items you can check yourself during a property viewing.

Checking Water-Related Areas

Kitchen:

• •Faucet and area under sink for water leak traces (staining or discoloration)
• •Drainage flow (turn the faucet fully on to check for blockages)
• •Degree of scorching and grease stains under the cooktop

Bathroom:

• •Mold on ceiling and walls (black stains)
• •Water pressure from showerhead and faucet
• •Drainage speed

Toilet:

• •Bidet toilet seat (washlet) operation
• •Water leak sounds in the tank (listen carefully)
• •Looseness at the joint between floor and toilet bowl

Sink:

• •Mirror fogging or cracks
• •Drainage flow
• •Smoothness of opening and closing cabinet doors

Checking Flooring, Walls, and Ceiling

• •Flooring: Walk around and listen for creaking (especially important in wood-frame buildings). Check for soft spots around water areas, which may indicate rot.

• •Walls: Look for vertical and horizontal cracks, especially at corners and around windows.

• •Ceiling: Look for water stains or discoloration from leaks (brown stains).

• •Windows: Check for warped frames and heavy condensation stains.

Checking Electrical and Equipment

• •Outlet operation (bring a phone charger to test all outlets)

• •Light switch operation

• •Air conditioner remote control and heating/cooling operation

• •Intercom and automatic lock operation

• •Location of gas shutoff valves (kitchen and bathroom)

Benefits of Choosing an Inspection-Completed Property

Under a Ministry of Land, Infrastructure, Transport and Tourism initiative, "Existing Home Inspection Guidelines" have been established, and properties with completed inspections serve as evidence of quality assurance.

For rental properties marked as "inspection completed":

• •The building condition has been objectively evaluated by a third party

• •The landlord is likely to take an active approach to building maintenance

• •Repair history and building condition documentation are often available

Simply asking your real estate agent, "Has this property been inspected?" can sometimes reveal the agent's building knowledge and integrity.

Combining with Move-In Inspection Checklists

Even if not as thorough as a professional home inspection, you must always create a move-in inspection checklist record.

Equipment Conditions to Record on the Checklist

1. Photos of all equipment appearance (taken with date and time stamp)

1. Location and extent of any damage, stains, and missing parts

1. Special notes (window glass cracks, age of air conditioner, etc.)

It is important to share the checklist with the management company and have them confirm it in writing. A record you create alone may not be officially recognized.

Tips for Taking Evidence Photos with Your Smartphone

• •Take photos with date and time stamps (screenshots showing date and time are also valid)

• •Take both wide-angle and close-up shots (so the specific location of any damage can be clearly identified)

• •Recording video of the entire space provides even more reliable documentation

Summary

Home inspections and equipment checks for rental properties are an important way to prevent problems after you move in.

• •Consider a professional inspection for older properties, single-family homes, or high-rent properties

• •During viewings, check water systems, flooring, walls, and electrical equipment yourself

• •Inspection-completed properties indicate the landlord's commitment to building maintenance

• •Move-in inspection checklists and evidence photos are essential (share with the management company)

• •If problems are discovered, submit a written repair request to the management company before moving in

Thorough inspection work is the foundation for a secure rental living experience.
