Fire code by license tier: residential, ryokan, minpaku

The license your operator holds decides what fire equipment is installed in your unit. The 建築基準法 (Kenchiku Kijun-hō — Building Standards Act) sets the structural rules. The 消防法 (Shōbō-hō — Fire Service Act) sets the equipment rules. The two acts read the building's use category off the license, then assign requirements. The operator does not pick the equipment. The paragraphs do.

For a midterm furnished apartment booking in Tokyo, the license is one of three. 共同住宅 (kyōdō jūtaku — apartment building, residential use). 旅館 / ホテル (ryokan / hoteru — inn or hotel, lodging use). 簡易宿所 / 住宅宿泊事業 (kan'i shukusho / jūtaku shukuhaku jigyō — simple lodging or registered minpaku). Each one sits in a different paragraph of 消防法施行令別表第一 (Shōbō-hō shikō-rei beppyō dai-ichi — Fire Service Act Enforcement Order, Appendix Table 1). The paragraph decides the equipment.

This article reads the three paragraphs side by side.

What your booking page already told you

A Tokyo midterm listing usually states one of three things. "30 nights minimum" with no license number visible: residential. "M-number" or 民泊登録番号 displayed on the page: minpaku under 住宅宿泊事業法. ホテル業法届出済 or "guest house," "hostel," "hotel" in the operator name: ryokan-class.

That label is the front door of the fire-code logic. For the licensing tiers themselves and the per-night pricing math, read the parent piece. This one picks up at the fire equipment.

A residential 共同住宅 sits under 別表第一 (5) 項ロ (go-kō ro — Item 5, sub-paragraph "ro"). A ryokan or hotel sits under 別表第一 (5) 項イ (go-kō i — Item 5, sub-paragraph "i"). A minpaku sits under (5) 項イ in most cases too. The Tokyo Fire Department reads it as lodging when the host does not live on-site, or when the lodging-area share crosses a threshold.

The "i" paragraph carries strict equipment rules. The "ro" paragraph carries relaxed ones. The whole article is one sentence past that: you are reading whose paragraph the unit is in.

Three levels: act, paragraph, equipment

Three levels stack on every Tokyo lodging unit. Always check all three.

Act level is which statute applies. The 建築基準法 governs how the building is built: fire-resistant frame, fire-rated walls and doors, escape routes, internal finish. The 消防法 governs what equipment is installed. Alarms, sprinklers, exit lights, extinguishers, evacuation gear. Both apply to the same building. Each one reads the building's use through its own table.

Paragraph level is which row of which table the building falls into. Building Standards Act 法27条 (hō ni-jū-shichi-jō — Article 27) lists 特殊建築物 (tokushu kenchiku-butsu — special-use buildings) by use, including hotel, ryokan, and apartment. Fire Service Act 別表第一 lists 防火対象物 (bōka taishōbutsu — fire-prevention target buildings) under sub-paragraphs, including (5) 項イ and (5) 項ロ. The paragraph names the use. The rule sits in the paragraph.

Equipment level is what gets installed. A residential 5項ロ unit at 60㎡ on the 4th floor of a manshon needs a battery 住宅用火災警報器 (jūtaku-yō kasai keihōki — residential fire alarm) in each bedroom and near the kitchen. A ryokan-licensed 5項イ unit of the same size in the same building needs a hard-wired 自動火災報知設備 (jidō kasai hōchi setsubi — automatic fire-alarm system). The wired alarm runs to a building control panel. It also picks up 誘導灯 (yūdōtō — illuminated exit signs) in the corridor. The walls are the same. The equipment behind them is not.

What 法27条 of the Building Standards Act actually requires

法27条 of 建築基準法 is the structural rule. It reads, in summary, that 特殊建築物 of certain uses and sizes must be 耐火建築物 (taika kenchiku-butsu — fire-resistant construction) or 準耐火建築物 (jun-taika kenchiku-butsu — quasi-fire-resistant construction). The size triggers are floor count and floor area.

For ryokan, hotel, and 共同住宅 use, the article requires 耐火建築物 when the building has 3 or more stories above ground. It requires 準耐火建築物 when the 2nd floor's lodging or residential area totals 300㎡ or more. Below those thresholds the article does not impose a class.

There is one relaxation. A 3-story building under 200㎡ total floor area is exempt from the 耐火 requirement, on conditions: it installs a 警報設備 (keihō setsubi — alarm system) and meets compartment-and-door rules. The 200㎡ figure is where small wooden townhouses converted to ryokan or minpaku get a softer rule. Above that, the 耐火 frame is mandatory.

The article matters at the booking stage because the structural class determines what you can hear and feel without the equipment. A 耐火 manshon transmits less smoke between units. A 準耐火 wooden 簡易宿所 in Asakusa transmits more. The license tier the operator chose limits what kind of building they could occupy in the first place.

For midterm furnished, the building is almost always a 耐火 concrete manshon. That is what residential and the larger minpaku/ryokan operators use. The structural rule cleared at the building's construction date. What changes per-unit is the 消防法 equipment.

Fire Service Act: the (5) 項イ vs (5) 項ロ split

Open 消防法施行令別表第一. Item (5) covers lodging and residential. Sub-paragraph イ covers ホテル、旅館、宿泊所その他これらに類するもの (hoteru, ryokan, shukuhakujo sono-ta korera ni rui-suru mono — hotels, inns, lodging facilities, and similar). Sub-paragraph ロ covers 寄宿舎、下宿、共同住宅 (kishukusha, geshuku, kyōdō jūtaku — dormitories, boarding houses, apartment buildings).

The split is the entire fire-equipment story. The two sub-paragraphs trigger different rows in 施行令第10条 through 第29条. Those rows name which equipment must be installed at which floor area.

Which paragraph minpaku lands in depends on conditions. The Tokyo Fire Department reads a 民泊 unit as (5) 項ロ under two conditions: the operator lives in the building, and the rental floor area is under half the building's total. The unit then follows the residential rule. The unit counts as (5) 項イ when either condition fails. Most Tokyo midterm-furnished minpaku run 家主不在型 (yanushi fuzaigata — owner-not-resident operation). That throws the unit into イ regardless of size. Which paragraph the operator's filing landed in is what decides the equipment.

Equipment rules for (5) 項イ — ryokan, hotel, most minpaku

Five pieces of equipment carry hard floor-area thresholds for an イ-classified unit.

• 消火器 (shōkaki — fire extinguisher). Required when 延べ面積 (nobe menseki — total floor area) is 150㎡ or more. Most Tokyo midterm studios sit under this threshold and clear with one extinguisher per floor.
• 自動火災報知設備. Required at any floor area for (5)項イ. The wired control-panel system is the default. A relaxation under 平成20年総務省令156号 (Heisei 20-nen sōmushō-rei 156-gō — Cabinet Office Ordinance 156 of 2008) allows 特定小規模施設用自動火災報知設備 (tokutei shōkibo shisetsu-yō jidō kasai hōchi setsubi — small-scale-facility automatic fire alarm). This is a wireless interconnected version, allowed when the building is 300㎡ or under. The wireless device looks visually like a residential battery alarm. It speaks to a master alarm in the corridor and trips all units when one detects smoke.
• 誘導灯. Required at all floors of an イ-classified building. Exit signs are illuminated, point to the stairwell, and back-up battery powers them through a power loss.
• 屋内消火栓設備 (oku-nai shōka-sen setsubi — indoor fire hydrant system). Required at 700㎡ or more for wooden construction, higher for fire-resistant. Most small ryokan and minpaku do not hit this.
• スプリンクラー設備 (supurinkurā setsubi — sprinkler system). Required at 6,000㎡ or more in the general case. Most Tokyo small-format ryokan and minpaku do not have sprinklers in-unit. A converted hotel floor of a manshon may have them. A 4-room minpaku conversion of a 1980s walk-up does not.

The wired alarm and the corridor exit signs are the visible difference between a (5)項イ unit and a (5)項ロ unit. Walk into the entryway. If the corridor has a green-and-white 非常口 (hijōguchi — emergency exit) lighted sign and a small red box marked 火災報知 (kasai hōchi — fire alarm), the building is on the (5)項イ rule. If you see only individual battery alarms in the unit, the building is on (5)項ロ.

Equipment rules for (5) 項ロ — apartment, residential

A (5)項ロ 共同住宅 unit follows a softer set of rules. The defaults: battery 住宅用火災警報器 in each living space, no corridor exit lights below a certain number of floors, and no in-unit sprinklers below 11階以上 (jū-ichi-kai ijō — 11 stories or more).

Three figures matter for 共同住宅:

• 自動火災報知設備. Required at 500㎡ or more total floor area, or in buildings of 11 stories and above. Below that, the consumer-grade 住宅用火災警報器 battery alarm is the only required device in the residential unit.
• スプリンクラー設備. Required for buildings of 11 stories and above, within those floors and on the floor itself. Most Tokyo midterm furnished sits in 5- to 9-story manshon. Sprinkler-free is the default.
• 平成17年消防庁告示2 (Heisei 17-nen Shōbō-chō kokuji 2 — FDMA Notification 2 of 2005, "On the location, structure, and equipment of specified apartment buildings"). Allows 特定共同住宅 (tokutei kyōdō jūtaku — specified apartment building), newer manshon with structural fire-compartmentation, to substitute alternative equipment for some standard installs. The notification is the reason a 2010s-built Tokyo manshon may have inter-unit fire-compartmentation walls but no corridor-wide alarm system. The structural compartmentation already meets the safety floor.

A concrete pattern. A 共同住宅 unit in a 7-story Setagaya manshon built in 2018 has 住宅用火災警報器 batteries in each bedroom and the kitchen. No corridor exit signs. No in-unit sprinkler. The same unit licensed as a minpaku and operated 家主不在型 counts as (5)項イ. It picks up the wireless 特定小規模 自動火災報知設備. It picks up corridor exit signs. The sprinkler picture does not change because the building is under 11 floors and under 6,000㎡ total. The structural shell is identical. What changes is the fire equipment, and that comes from the license.

Reading what is in your unit

You can read most of the equipment without opening any panels. Three artifacts tell the story.

The first is the 設置届 (secchi todoke — installation notification) sticker the building posts in the lobby or near the mailboxes. It lists what equipment was registered with the local fire station. Look for 自動火災報知設備 (yes / no), 屋内消火栓 (yes / no), スプリンクラー (yes / no). The sticker is required and almost always there in a Tokyo manshon.

The second is the corridor's emergency-exit sign. Look for a lighted green-and-white sign with the figure-running pictogram, mounted above the stairwell door, with a separate battery housing visible. That is a 誘導灯 and signals (5)項イ. No sign or only a static reflective sticker: that is (5)項ロ. The pictogram and lighting state are the easiest things to spot at a glance.

The third is the alarm device in the unit. A consumer-grade plastic disk on the ceiling with a small button, no wires visible, replaceable battery: that is a 住宅用火災警報器, residential. A larger device with a wired conduit running to it, a "test" lamp, and a label citing 自動火災報知設備 means the alarm is wired to the building's control panel, (5)項イ. The wireless 特小 version sits in between. It runs on battery but has an antenna housing and a serial number that pairs to the master.

If the unit has the consumer alarm only and you booked a stay under 30 nights, something's been filed wrong somewhere. Walk past the building's notification sticker and check the licensing tier on the operator's page again. The mismatch is worth raising before check-in.

When the equipment fails the inspection

The 消防署 (shōbōsho — fire station) inspects (5)項イ buildings on a recurring cycle, usually 6 months or 1 year, under 消防法第17条の3の3 (Shōbō-hō dai-jū-nana-jō no san no san — Article 17-3-3). The inspector files a report with the building owner. A failed item triggers a written 指導 (shidō — guidance) notice and a re-inspection date.

If the inspection finds the wired alarm dead, the operator typically cannot legally accept new bookings into that unit until a re-inspection clears. The booking calendar quietly closes on the dates while the contractor swaps the device. The fix takes 3 to 7 days for an alarm replacement, longer for a sprinkler retrofit.

You do not call the fire station. The operator does. If a booking is canceled or rescheduled because of an inspection finding, the operator will say "fire-equipment maintenance" without specifying the device. They are following the rule the inspection report named. There is no shame in the cancellation. The system worked the way it was supposed to.

What to look for before you book

Three checks settle most fire-code questions before the booking confirms.

• Read the license tier off the listing. Residential 30+ minimum, minpaku M-number, or ryokan act registration. The tier predicts the equipment overlay above.
• Ask the operator one question. "Is the unit a (5)項イ or (5)項ロ classification under 消防法施行令?" A real operator answers in one sentence: イ for ryokan and most minpaku, ロ for residential. An operator who cannot answer is not running on a license they understand.
• Walk the lobby in the first 10 minutes after check-in. The 設置届 sticker, the corridor exit sign, and the alarm device tell you what the operator filed. If anything in your unit looks softer than the sticker, message the operator the same day. Inspections close on this.

The fire equipment in a Tokyo lodging unit is not chosen by the operator's preference. The license decides which paragraph applies. The paragraph names the equipment. The equipment is what the inspection checks. You can read the chain backward from the device on the ceiling to the act in the books.
