When purchasing real estate, many people find themselves torn between choosing a condominium or a detached house. Each option has its own advantages and points to consider. In this column, we organize and explain those differences.
Suitability by Lifestyle
There is no one-size-fits-all answer as to whether a condominium or a detached house is better. The right choice depends on your lifestyle and long-term plans.
One of the major advantages of condominiums is their excellent location, disaster resistance, and security. Many condominiums are located just a few minutes’ walk from a station, and some are even directly connected to one—features that are unique to condominiums.
On the other hand, detached houses are characterized by a high level of privacy and greater freedom when it comes to renovations.
If you live in an urban area and prioritize commuting convenience and disaster resistance, a condominium is generally the better option. Conversely, if you live in a suburban area where commuting by car is the norm, or if you prefer a quiet living environment even if it is a bit farther from the station, a detached house may be more suitable.
Comparison of Building Performance and Features
Next, let’s compare the performance of the buildings themselves. Here, we look at four aspects: security, sound insulation, earthquake resistance, and fire resistance.
In terms of security, condominiums are superior. They are often equipped with auto-lock systems and security cameras, making them more secure overall. While home security systems for detached houses have improved in recent years, the number of burglary cases is still overwhelmingly higher for detached houses.
Regarding sound insulation, considering the materials used for walls, floors, and ceilings, condominiums generally offer better soundproofing than detached houses. However, since people live in units above, below, and next door, a certain level of consideration for noise is still necessary.
Detached houses, by contrast, are physically separated from neighboring homes by exterior walls and roads, giving them a higher degree of independence. In fact, noise-related issues tend to occur less frequently in detached houses than in condominiums. In other words, while condominiums may perform better as standalone buildings, detached houses can sometimes be more suitable depending on the surrounding living environment.

Next, let’s compare earthquake and fire resistance. Condominiums built under current earthquake resistance standards are designed to suffer little to no damage in earthquakes of around seismic intensity 5, and to avoid collapse even in major earthquakes of seismic intensity 7. By contrast, in earthquakes of intensity 7, many detached houses may collapse.
Furthermore, condominiums constructed with non-combustible reinforced concrete offer excellent fire resistance. Compared with detached houses, which are typically wooden structures, condominiums are far superior in terms of fire safety. This difference also affects fire insurance premiums, which tend to be lower for condominiums than for detached houses.
Differences in Maintenance Costs, Management, and Asset Value
In terms of building performance, condominiums excel in many areas. However, from a cost perspective, condominiums tend to involve higher ongoing expenses. The following three costs are incurred only in the case of condominiums:
・Parking Fees
Using an on-site parking space requires an additional fee. Parking fees vary significantly depending on location, but in Tokyo’s 23 wards, the average is around ¥30,000–¥40,000 per month.
・Management Fees (Common Area Fees)
These are paid to the management company for the upkeep of common areas such as the entrance and garbage disposal areas. The typical monthly cost is around ¥10,000–¥20,000.
・Repair Reserve Fund
Repairs include work such as fixing damage to exterior walls and corridors, and replacing shared facilities used by residents. In condominiums, large-scale repair work is carried out every 10 to 20 years, and residents contribute to this through monthly payments of about ¥10,000–¥20,000. The repair reserve fund is not included in the purchase price of the condominium.
In the case of used condominiums, there are instances where the management association does not function properly, resulting in insufficient repair reserves. In such cases, residents may suddenly be required to pay a large sum for repairs. For this reason, it is strongly recommended to check the status of the repair reserve fund before purchasing.
Ease of Resale and Market Trends
There may come a time when you need to sell your property due to changes in your life stage. In terms of ease of resale, condominiums have an advantage. Condominiums located close to stations and offering high convenience tend to enjoy strong demand.
Detached houses, on the other hand, are often located farther from stations, and due to their size and layout, it can be difficult to find buyers who are specifically looking for “that particular layout in that specific area.” If you are considering future resale potential, a condominium is generally the better choice.
