As remote work has become more common, more people want to register a rental apartment as their company’s head office. However,whether a company can be registered at a rental apartment depends on the lease terms and building rules, and doing so without permission creates serious risk.This article explains the legal points that both owners and tenants should understand.

Is it legally possible to register a company at a rental apartment?

Company registration itself is not prohibited by law. However,whether it is allowed depends on the lease agreement and building rules.

It may be a breach of contract in residential properties

Many rental apartments are leased for “residential use only,” and some contracts expressly state that “the tenant may use the property only as a residence.”In that case, using the unit as an office or registering a company there would breach the contract.

Registration may be possible with the owner’s permission

Even in a residential property,there are cases where company registration is allowed if the owner gives permission.There may be room to negotiate, so the first step is to ask and discuss it openly.

What happens if you register a company without permission?

The idea that “it is fine as long as no one finds out” is risky.Once a company is registered, the address is published on the National Tax Agency’s corporate number search siteso the owner can verify it. The risk of discovery is always present.

Risks of using a rental apartment as an office without permission

Unilateral termination of the lease

If unauthorized office use is discovered in a residential-only property,the owner may seek termination of the lease and eviction for violating the duty to use the property as agreed.

Claim for damages

If office use causes disputes with neighbors or leads other tenants to move out,there is a risk that the owner will claim damages.

Your home address becomes public online

When a company is registered,the representative’s name, address, and stated capital become searchable by anyoneYou also need to consider the risk of clients or business partners showing up unannounced.

Permit and license applications may be rejected

In industries that require permits or licenses, such as secondhand goods dealing or real estate brokerage,approval may not be granted if the address is a residential property.For real estate brokerage, a dedicated entrance and clearly defined space are required.

Leased office

A property leased for business use. It can accommodate visitors, signage, and permit or license applications, butinitial and monthly costs are higherwhich is the main drawback.

Coworking space

These can often be used for around JPY 10,000 to 30,000 per month,and some facilities offer an address for company registration, mail handling, and meeting room access.There are more than 2,000 such facilities in Japan, and over 40% are concentrated in Southern Kanto.

Shared office

This format offers private or semi-private dedicated space more often than a coworking space.It is less expensive than a leased office and offers the advantage of a prime business addressWhether company registration is allowed must be confirmed with each facility individually.

Virtual office

A service that lets you rent only an address without physical workspace.It can be used from a few thousand yen per month and is highly cost-effective.However, it may not be usable in industries that require permits or licenses.

SOHO-friendly property

A residential property where office use is also permitted.You may not be able to put up signage, but some properties do allow company registration.Advance confirmation is essential.

Differentiation strategies in rental property managementFrom that perspective as well, the management framework for properties that allow office use is directly tied to profitability.

FAQ

Q. If I register a company at a residential apartment, will the owner find out right away?
Because the National Tax Agency’s corporate number search and Legal Affairs Bureau records can be checked, there is a risk of discovery even if you have few visitors. It is difficult to keep it hidden indefinitely.
Q. If I am a sole proprietor, can I run a business from home without company registration?
A sole proprietor does not need company registration, but operating a business in a residential property may itself violate the permitted use of the property. Extra caution is needed if you expect frequent visitors.
Q. Are there benefits for an owner in allowing office use?
Allowing office use can have benefits, such as consumption tax applying to the rent and greater clarity about the tenant’s use of the property. At the same time, it also requires managing risks such as noise and increased visitor traffic.
Q. How can I find a SOHO-friendly property?
You can filter listings on real estate portals using conditions such as “SOHO allowed” or “office use allowed.” Always confirm whether company registration is permitted before signing a contract.
Q. Can a virtual office address be used to open a bank account?
Policies differ by financial institution. Major banks tend to apply stricter screening, so you should confirm with the bank before using the address.
