Finding premises for a residential-type fee-paying elderly home — zoning, fire equipment and floor area

In short: for a residential-type fee-paying elderly home, what bites first about the premises is (1) zoning — a fee-paying elderly home counts as an "elderly home" among child-welfare-type facilities and can be built in every use zone except the exclusive industrial zone; (2) fire equipment — whether it falls under item (6)-ro or (6)-ha of the Fire Service Act Enforcement Order's Appended Table 1 decides whether sprinklers are required regardless of area or only at 6,000㎡ or more; and (3) room area — there is no single statutory figure, but the standard operating guideline suggests private rooms of 13㎡ or more per resident. The notification under Article 29(1) of the Old-Age Welfare Act is made by the operator to the prefectural governor; our company only provides property information.

When you set out to open a residential-type fee-paying elderly home, you first hesitate over "what building or house to rent (or buy)." Articles on serviced housing for the elderly (sakoju) or care-attached homes line up conditions like 25㎡ per unit, the "specified facility" designation and staffing — but the residential type rides a different scheme, so the order in which you check the premises also changes. This article is for operators considering a residential-type fee-paying elderly home, and for real estate practitioners searching for business premises: what you can confirm before signing, set out from the statutes and national materials. Investigation, brokerage and lease intermediation are handled by our company (Yotsuba Real Estate Co., Ltd.) as information; acceptance of the notification is judged by the prefectural governor.

How do the premises requirements differ from serviced housing (sakoju) and care-attached homes?

The same "housing for the elderly" carries different scheme demands on the premises. The Ministry of Health, Labour and Welfare's standard operating guideline divides fee-paying elderly homes into four types.

Type	Where care comes from when needed	How it rides the scheme
Care-attached (general)	Specified facility resident care the home itself provides	Requires the specified-facility designation (Long-Term Care Insurance Act)
Care-attached (external-service)	A contracted care-service provider	Same (designated as external-use type)
Residential type	Local home-visit care etc. the resident chooses	Only the notification under Old-Age Welfare Act Art. 29(1). No specified-facility designation
Health type	Must terminate and move out when care becomes necessary	Notification only

The residential type "takes no specified-facility designation and uses external home-visit care." So the 25㎡-per-unit registration standard for sakoju (see conditions for premises that can become sakoju) and the staffing/facility designation standards for care-attached homes do not simply apply. For how the "facility-type" care offices differ in premises, see also care offices are decided by zoning. The thinking on business premises is at investment / business property, and searching for a base at business base / office.

In which use zones can you open a residential-type fee-paying elderly home?

A fee-paying elderly home falls under "elderly home" in the Building Standards Act's Appended Table 2, treated as one of the child-welfare-type facilities (Enforcement Order Art. 19, Art. 115-3 item 1). Child-welfare-type facilities can be built in every use zone except the exclusive industrial zone. Not as free as a clinic, but on the same footing as a nursery, buildable even in a Category 1 low-rise exclusive residential zone.

Use zone	How an elderly home is treated (guide)
Category 1 / 2 low-rise exclusive residential	Buildable (note height, setback and scale limits; often up to two storeys)
Mid/high-rise, residential, quasi-residential	Easy to build
Neighbourhood commercial, commercial, quasi-industrial, industrial	Easy to build
Exclusive industrial	Not buildable (elderly homes not listed)

That said, when converting an existing apartment or house into a residential-type home, apart from the zoning, whether a change-of-use confirmation application is needed under Building Standards Act Art. 87(1) becomes an issue (below). Both the zoning feasibility and the need for a change-of-use application can be checked at the specified administrative agency before signing.

From what floor area do sprinklers and auto fire alarms become mandatory?

Area bites hardest on fire equipment. In the Fire Service Act Enforcement Order's Appended Table 1, a fee-paying elderly home splits into item (6)-ro or (6)-ha by the residents' condition, and the sprinkler standard changes entirely.

Category	How the fee-paying elderly home is classified	Sprinkler equipment	Auto fire alarm
(6)-ro	Mainly housing care-needing persons who have difficulty evacuating	Required regardless of area (formerly 275㎡+ → in principle all, by Cabinet Order No. 333 of 2014, effective 1 April 2015)	Required regardless of area
(6)-ha	Not falling under (6)-ro (evacuation-difficult care-needing persons not the main body)	Required at 6,000㎡ or more	Required at 300㎡ or more

Item (6)-ro was tightened in stages after the 2006 dementia group-home fire in Omura, Nagasaki, and now sprinklers are required regardless of area. However, a facility of less than 275㎡ total floor area that has a structure suppressing the spread of fire (the structure defined in Art. 12-2 of the Fire Service Act Enforcement Regulations) needs no sprinkler. A facility under 1,000㎡ may install a water-supply-connected sprinkler for specified facilities.

Whether a residential-type home is (6)-ro or (6)-ha is judged by the fire authority from the residents' actual condition (whether it mainly houses care-needing persons who have difficulty evacuating). Residential types often assume independent or lightly-dependent residents and frequently fall under (6)-ha, but if judged (6)-ro on the facts, even a small facility needs sprinklers. Before deciding on the premises, confirm with the fire authority, attaching your assumed resident profile. The (6)-ro / (6)-ha thinking for other welfare facilities is also set out at premises for after-school day services.

When converting an existing apartment or house, what do you check under the Building Standards Act?

Residential-type homes are often opened by converting an existing apartment, house or dormitory. Here is what to check under the Building Standards Act.

Point	Why it bites	Basis
Change-of-use confirmation	If the part used for the home (a special building) exceeds 200㎡, a confirmation application is needed	Building Standards Act Art. 87(1), Art. 6(1) item 1
Zoning feasibility	Not buildable in the exclusive industrial zone	Same Act, Appended Table 2
Lighting, ventilation, stairs, fire	Room lighting (Art. 28), direct stairs / escape routes, fire compartments	Same Act and Order
Inspection certificate / existing non-conformity	How far current standards reach on rebuild; whether an inspection certificate exists	Same Act, Art. 7 etc.

Because "apartment (dormitory)" to "fee-paying elderly home (child-welfare-type facility)" is a change of use, a change-of-use confirmation is needed for any part over 200㎡. Apartments and elderly homes differ in technical standards for lighting, stairs and escape, and an existing building may not meet them as is. For the rebuild / frontage thinking when buying a used building to convert, inherited non-rebuildable property is also helpful. Confirm the need for a change of use and current conformity with an architect and the specified administrative agency before signing.

As for room area, there is no single statutory figure under the Old-Age Welfare Act, but the standard guideline suggests "general rooms, care rooms and temporary-care rooms shall be private rooms, 13㎡ or more per resident" (and if all care rooms are private and 18㎡+ each, the corridor-width requirement changes). This is a different measure from sakoju's 25㎡ per unit. The standard guideline is a technical notice; actual operation varies among prefectures and designated cities.

Before securing the premises, how do you order it with the Old-Age Welfare Act notification?

A residential-type home cannot open on premises alone. Article 29(1) of the Old-Age Welfare Act requires a person establishing a fee-paying elderly home to notify the prefectural governor (the mayor for designated / core cities) in advance, before establishing it. The standard guideline asks that this notification be made "promptly after the building confirmation, before establishing the home," and that resident recruitment follow the notification. Because it spans business entities, we separate who does what.

What to do	Who
Investigation, brokerage, lease intermediation	Licensed real estate agent (Yotsuba Real Estate Co., Ltd.)
Preparing the Art. 29 notification documents	Administrative scrivener (Yotsuba Administrative Scrivener Office); the operator files with the prefecture
Design/installation of fire equipment (sprinkler, alarm)	Fire equipment engineer / contractor (pre-consult the fire authority)
Change-of-use confirmation, lighting/escape conformity	Architect
Ownership-transfer registration when buying	Judicial scrivener
Tax on the lease / opening	Tax accountant

The key to the order is "confirm the fire category and the need for a change of use before securing the premises." This avoids the backtracking of learning after signing that a (6)-ro judgment requires sprinklers, or that a change of use leaves lighting short. Acceptance of the notification itself is judged by the prefectural governor; our company only provides property information.

Frequently asked questions

Q. Does a residential-type home also have a 25㎡-per-unit area standard like sakoju?
A. There is no single statutory floor-area standard under the Old-Age Welfare Act. The standard operating guideline suggests "private rooms, 13㎡+ per resident," and operation varies among prefectures and designated cities. Sakoju's 25㎡ per unit (18㎡ if common areas are ample) is a registration standard under the Elderly Housing Act, a separate scheme. Confirm the operating guideline for your planned site at the outset.

Q. If it is small, can we open without a sprinkler?
A. It depends on the category. For (6)-ha (evacuation-difficult care-needing persons not the main body) it is required at 6,000㎡+, but for (6)-ro (mainly housing evacuation-difficult care-needing persons) it is required regardless of area. Even under (6)-ro, a facility under 275㎡ with a fire-spread-suppressing structure (Enforcement Regulations Art. 12-2) is exempt. The category is judged by the fire authority from the residents' actual condition, so confirm in advance with your assumed resident profile attached.

Q. Can we rent a used apartment and make it a residential-type home?
A. Sometimes. But converting from an apartment (dormitory) to a fee-paying elderly home (child-welfare-type facility) is a change of use, so a change-of-use confirmation (Building Standards Act Art. 87(1)) is needed for any part over 200㎡, and technical standards for lighting, escape and fire must be met. It cannot be built in the exclusive industrial zone. Confirm current conformity and the need for a change of use with an architect and the specified administrative agency before signing.

Q. Which should we advance first, the premises or the notification?
A. It is safer to confirm the fire category ((6)-ro/ha) and the need for a change of use before securing the premises. The Art. 29(1) notification is filed "before establishing" to the prefectural governor; the standard guideline asks you to notify promptly after the building confirmation and recruit residents after notifying. Document preparation is undertaken by an administrative scrivener, and the notification itself is filed by the operator to the prefecture.
