Last updated: About 3 min read

Older apartments often come with lower rent, but concerns about outdated facilities and limited sound insulation are also common. Even so, older properties offer strengths that newer buildings may not, including lower housing costs, convenient locations, and units that allow DIY improvements. This article explains in detail the advantages and disadvantages of old apartments, along with practical tips for comfortable living and effective layout ideas.

From how many years old is an apartment considered old?

There is no strict definition of an old apartment. In general, properties that are around 3 to 5 years old are considered relatively new, while properties that are 20 to 30 years old or more are considered older. Many older properties have already been renovated, so ruling them out based on building age alone may mean missing a worthwhile option. It is important to confirm the actual condition during a viewing.

What are the advantages of older apartments?

Older apartments offer the following benefits that are worth noting.

Rent tends to be lower

Because rent is lower than for newly built or relatively new properties, you can reduce both upfront costs and your monthly financial burden. For people who want to keep housing costs under control, older properties can be a strong option.

Conveniently located properties are also easier to find

Relatively new properties near stations often come with higher rent, but with older properties, there is a chance of finding a well-located home at a more reasonable price. There are also more listings available, which expands your choices.

Some properties allow DIY

Depending on the landlord, there are also properties where DIY or renovation is permitted. This makes it possible to create a space that suits your preferences, such as by changing wallpaper or repainting walls.

Many properties have already been renovated

There are also many properties that have been renovated as a vacancy countermeasure, such as converting Japanese-style rooms into Western-style rooms or replacing kitchens and toilets.

What are the disadvantages and points of caution with older apartments?

While there are clear benefits, it is also important to pay attention to the following drawbacks.

Outdated facilities

Equipment such as water heaters and air conditioners may still be older models, which can make them less convenient to use. If you notice a problem with the facilities, the basic rule is to contact the management company rather than trying to repair it yourself.

Limited sound insulation

Older wooden properties in particular often have weaker sound insulation, so noise from neighboring rooms may be noticeable. Thermal insulation also tends to be lower, which can make additional heating necessary in winter.

There may be a possibility of old earthquake-resistance standards

Properties built before June 1981 may have been constructed under older earthquake-resistance standards. However, some properties have also undergone seismic reinforcement work and now meet newer earthquake-resistance standards, so be sure to confirm details about earthquake resistance and earthquake insurance before signing a contract.

Pest control may be necessary

Because lower airtightness and building deterioration can make it easier for insects to enter, you should take preventive measures such as smoke-type insecticides or poison bait.

What points help make living in an old apartment more comfortable?

By keeping the following points in mind when choosing a property, you can create a more comfortable living environment.

  • Check the management condition:Review cleaning and maintenance of common areas
  • Check the facilities:Inspect wear in water-related areas and confirm that the water heater and air conditioner work properly
  • Check the structure:Reinforced concrete buildings generally offer better sound insulation and durability
  • Check whether DIY is allowed:Confirm in advance with the landlord or management company
  • Confirm sound insulation:During the viewing, tap the walls to gauge thickness and, if possible, check conditions at night as well

How can you improve the weak points of an older apartment?

By understanding the weak points of older properties and improving them appropriately, you can achieve a more comfortable home environment.

Moisture and mold prevention

Older apartments tend to retain moisture, so wipe away window condensation regularly and arrange furniture with airflow in mind.

How to address drainpipe odors

As drainpipes age, odors can become more noticeable. In addition to regular maintenance, using an aroma diffuser can also be effective.

Smarter storage solutions

Limited storage can be addressed with "lifted storage" solutions such as tension rods and wall shelves.

Reduce visual heaviness with lower furniture

If the ceiling is low, choosing lower furniture can make the room appear more spacious.

Stylish layout ideas that make use of older features

Here are ways to make use of the distinctive qualities of older apartments and create a stylish living space.

  • Replace fusuma with partitions:This can create a more open feel
  • Concrete-look wallpaper:For a modern, designer-style atmosphere
  • Use rugs to divide the space:Separate the kitchen and living area in a stylish way
  • Incorporate Japanese-style interiors:A Japanese-Western mixed style that pairs well with tatami and shoji
  • Unify the room with retro items:Turn age into character and style

Frequently Asked Questions (FAQ)

Q. From how many years old is an apartment considered old?

In general, properties that are 20 to 30 years old or more are considered older, but there is no strict definition. If a property has been renovated, it may feel far more comfortable than its age suggests.

Q. How much cheaper is the rent for older properties?

Compared with relatively new properties in the same area and with a similar layout, rent tends to be about 10,000 to 30,000 yen lower. Depending on the location, the gap can be even greater.

Q. Are properties built under old earthquake-resistance standards dangerous?

Not necessarily. Some properties have already undergone seismic reinforcement work, so it is advisable to confirm the details with the management company or landlord.

Q. What are effective soundproofing measures for old apartments?

Soundproof curtains, arranging furniture to buffer walls, and installing soundproof mats can all be effective. It is also important to check sound insulation carefully during the viewing.
