Opening a laundry (cleaning establishment): what to check in the property's zoning and structural equipment

In short: a property for a laundry that receives clothing and washes it on site (a "cleaning establishment") is narrowed first by two things — zoning and the structural-equipment standards. A general cleaning establishment that installs commercial powered washers is usually treated as a "factory using a motor" under the Building Standards Act, so its zoning treatment differs from a mere pick-up counter or an unmanned coin laundry where customers wash their own clothes. To open, you must file the notification under Article 5(1) of the Laundry Business Act with the prefectural governor (public health center) in advance, and you cannot use the premises until you have passed the inspection and confirmation under Article 5-2. Each cleaning establishment must have at least one licensed laundry technician (Article 4(1)). The final judgment rests with the public health center and the designated administrative agency; we handle the property-side feasibility check and the lease brokerage.

This article is for operators opening a cleaning establishment in Tokyo and for owners leasing the premises. It sets out what can be checked before signing, from the Laundry Business Act, the Building Standards Act, the City Planning Act and the Sewerage Act, and from Ministry of Health, Labour and Welfare and Tokyo materials. What we handle is finding the property, the explanation of important matters, and the lease brokerage. We focus on the property-side requirements — zoning, water supply and drainage, and structural equipment.

In which zoning district can a cleaning establishment open?

Article 2 of the Laundry Business Act (Act No. 207 of 1950) defines "laundry business" as the business of washing clothing and other textile or leather products in their original form using solvents or detergents, and defines a "cleaning establishment" as the operator's facility for processing, or receiving and delivering, laundry. Of these, a general cleaning establishment that installs commercial washers and washes on site is usually treated as a "factory using a motor" under the Building Standards Act. What may be built in each zoning district is set by Article 48 of the Building Standards Act and Appended Table 2.

A pick-up counter that only receives laundry and sends it to an outside plant has no motor, so it may be treated as a "shop for a service business such as a clothing store," and may be allowed in districts stricter than those for a factory. Mistaking the two turns into the accident of choosing a property that zoning does not allow.

Zoning district	Guide for a cleaning establishment with washing equipment (treated as a factory)
Category I / II low-rise residential exclusive; agricultural residential	A factory is in principle not allowed (a pick-up counter may be allowed in part as a service-business shop)
Category I / II medium-to-high-rise residential exclusive	A factory is in principle not allowed
Category I / II residential; quasi-residential	Generally allowed if a factory using a motor has a workroom floor area of 50 m² or less in total
Neighborhood commercial; commercial	Generally allowed if the same is 150 m² or less
Quasi-industrial; industrial; exclusive industrial	Looser (but flammable-solvent dry cleaning is restricted in quasi-industrial)

Dry cleaning that uses flammable solvents (such as petroleum-based solvents) is restricted a step further; it is in principle not allowed even in quasi-industrial districts, and may require permission under the proviso to Article 48 of the Building Standards Act. Treatment changes with whether it is mainly wet washing and which solvent is used. Zoning can be checked on the map in the Ministry of Land, Infrastructure, Transport and Tourism's "Real Estate Information Library," but whether it is read as a shop or a factory, and the floor-area threshold, depend on the operation of the designated administrative agency (the local building official). Confirming the treatment with the designated administrative agency before signing is the sure way.

What structural-equipment standards does a cleaning establishment require?

Even if the property clears zoning, the next question is whether it can meet the structural-equipment standards of the Laundry Business Act. Water supply, wastewater and the placement of machines are the focus.

Article 3 of the Laundry Business Act sets out the measures an operator must take. Article 3(2) requires a cleaning establishment that washes to have at least one commercial washer and one dehydrator each (the dehydrator is excepted where a washer with a dehydrating function is provided). Article 3(3) requires the floor of the wash area to be built of impermeable material (concrete, tile, etc., through which wastewater does not seep) and to have an appropriate gradient and a drain. The Tokyo Metropolitan enforcement ordinance of the Laundry Business Act adds that ventilation, natural lighting and illumination inside the cleaning establishment must be sufficient, that a container be provided to process laundry requiring disinfection separately from other laundry, and that washed and unwashed laundry be kept apart.

Item to check	Key of the standard	Main basis
Wash-area floor / drainage	Built of impermeable material, with an appropriate gradient and a drain	Laundry Business Act Art. 3(3)
Commercial machines	At least one washer and one dehydrator each (dehydrator unnecessary if a washer with dehydrating function)	Same Act Art. 3(2)
Ventilation / lighting	Sufficient inside the cleaning establishment	Tokyo enforcement ordinance
Disinfection / separation	Container to separate items requiring disinfection; keeping washed and unwashed items apart	Same Act Art. 3 / Tokyo ordinance
Water supply / toilet, etc.	Supply of water fit for drinking; hygiene of hand-washing and toilet	Tokyo ordinance

The public health center's check of structural equipment has parts in common with beauty and barber shops. Whether the property's layout allows the work area to be separated from the area customers enter is also set out at what to check in a property for a beauty or barber shop. Details differ by municipality, so confirm the standards with the public health center for the planned site.

How do the property requirements differ between an unmanned coin laundry and a cleaning establishment?

Even among shops that "wash," an unmanned coin laundry where customers wash their own clothes and a cleaning establishment that receives and washes clothing occupy different legal positions. Mistaking them means dropping a required notification.

An unmanned coin laundry where customers wash their own clothes (a "coin-operated cleaning business") does not receive and deliver laundry, so in principle it is not subject to the "cleaning establishment" opening notification under the Laundry Business Act. Many municipalities require an opening notification under guidance based on the national "Guidelines on Hygiene Measures for Coin-Operated Cleaning Business Facilities," but this is separate from a statutory notification. A cleaning establishment that receives laundry and washes it on site, by contrast, may not be used until, under Article 5(1) of the Laundry Business Act, it has filed the opening notification with the prefectural governor in advance, and, under Article 5-2, has passed the governor's inspection and received confirmation that its structural equipment conforms to the standards. In addition, under Article 4(1), at least one licensed laundry technician must be placed at each cleaning establishment (a pick-up counter that only receives and delivers is excepted).

Form of shop	Legal position	Notification / inspection	Laundry technician
Unmanned coin laundry (self-wash)	Coin-operated cleaning business	Opening notification under municipal guidelines (not a statutory duty)	Not required
Cleaning establishment (receive and wash on site)	Cleaning establishment under the Laundry Business Act	Art. 5(1) opening notification + Art. 5-2 pre-use inspection/confirmation	At least one at each (Art. 4(1))
Pick-up counter (receive/deliver only)	Cleaning establishment under the Laundry Business Act	Art. 5(1) opening notification	Not required (Art. 4(1))

The property requirements for an unmanned coin laundry are set out at where can a coin laundry open?. Preparation of the opening-notification documents under the Laundry Business Act is the work of an administrative scrivener; confirming the legality of the building's use and structure is for an architect and the designated administrative agency; and the judgment of whether opening is possible is made by the public health center. We (the real estate side) handle finding the property, the explanation of important matters and the lease brokerage, and refer the notification to an administrative scrivener, whom you engage directly.

Before signing, what should you confirm about water supply, drainage, electrical capacity and ventilation?

A cleaning establishment uses much water and heat, so it cannot open if the property's water supply, electricity and ventilation do not fit. Before signing, four points matter: drainage capacity, electricity and gas capacity, and ventilation and fire safety.

Because it uses a large volume of water, check whether the supply and drainage pipes have the bore to withstand simultaneous operation of the washers and whether the premises can connect to the public sewer. When draining into the sewer, the discharge must conform to the standards under Article 12-2 etc. of the Sewerage Act (Act No. 79 of 1958), and drainage containing lint or oil may require a treatment facility. If a dry-cleaning machine using solvents such as tetrachloroethylene is added, confirm at the design stage whether it falls under a "specified facility" of the Water Pollution Prevention Act (Act No. 138 of 1970). On the equipment side, commercial washers, dryers and boilers require power (three-phase 200 V) and gas capacity that the existing supply may not meet. Because ignition of lint accumulated in a dryer's duct or lint filter can cause fire, a fire-safety check is also needed.

Point to check	What to look at	Main party to confirm with
Drainage capacity	Bore of supply/drainage pipes to withstand simultaneous washer operation	Equipment contractor / architect
Sewer / drainage	Connection to the public sewer; discharge standards (Sewerage Act Art. 12-2 etc.); need for a treatment facility	Municipal sewerage section / equipment contractor
Water-quality control	Whether a solvent dry-cleaning machine, if added, makes it a specified facility under the Water Pollution Prevention Act	Municipal environment section / equipment contractor
Electricity / gas	Power (three-phase 200 V) service and contract capacity; gas supply type and capacity	Power/gas company, electrician
Ventilation / fire	Ventilation of solvents and humidity; position and structure of fire-using equipment (Fire Service Act Art. 9 / municipal ordinance)	Fire station with jurisdiction / equipment contractor

The design of water supply, drainage, gas and ventilation, and whether a change-of-use confirmation application is needed, are the domain of the equipment contractor, architect and designated confirmation and inspection body. We organize the property's current water supply and drainage, the feasibility of the sewer connection and the zoning, and hand you a first sorting of what to confirm with the architect, equipment contractor and public health center.

Frequently asked questions

Q. To open a cleaning establishment that receives clothing and washes it on site, is a notification required?
A. Yes. Under Article 5(1) of the Laundry Business Act, a person intending to open a cleaning establishment must notify the prefectural governor (public health center) in advance. Further, under Article 5-2, the establishment may not be used until it has passed the governor's inspection and received confirmation that its structural equipment conforms to the standards. Preparation of the notification documents is undertaken by an administrative scrivener, and the judgment of whether opening is possible is made by the public health center.

Q. Can a cleaning establishment open in a first-floor tenancy in a residential area?
A. A cleaning establishment with washing equipment is usually treated as a "factory using a motor," so it is in principle not allowed in Category I / II low-rise residential exclusive districts or medium-to-high-rise residential exclusive districts. In Category I / II residential and quasi-residential districts, it is generally allowed if the workroom floor area is 50 m² or less in total. A pick-up counter that only receives, without washing, may be allowed as a service-business shop. The line depends on the operation of the designated administrative agency, so confirm before signing.

Q. How do the required procedures differ between an unmanned coin laundry and a cleaning establishment?
A. An unmanned coin laundry where customers wash their own clothes does not receive and deliver laundry, so in principle it is not subject to the cleaning-establishment opening notification under the Laundry Business Act, and only an opening notification under municipal guidelines applies. A cleaning establishment that receives laundry and washes it on site requires the Article 5(1) opening notification and the Article 5-2 pre-use inspection/confirmation, and must have at least one laundry technician at each establishment.

Q. Must a laundry technician always be stationed at the premises?
A. Article 4(1) of the Laundry Business Act requires at least one licensed laundry technician to be placed at each cleaning establishment that washes (a pick-up counter that only receives and delivers is excepted). The technician's license and placement are qualification and personnel requirements, separate from the property-side requirements. Personnel arrangement and labour design go to a certified social insurance labour consultant, and obtaining the license is the individual's own procedure — confirm these apart from the property's feasibility.
