你知道嗎？台灣的有蓋人行道是私人財產，但法律上屬於公共用地。

Walk down almost any older street in Taiwan when it’s raining and you can stay nearly dry the whole way. The ground floor of each building is pulled back from the road, and the floors above stretch out over a covered walkway held up by a row of pillars. In Mandarin that walkway is a qílóu (騎樓). Grandparents call it tîng-á-kha (亭仔跤) in Taiwanese Hokkien and 店亭下 in Hakka. Here’s the surprising part: the strip of floor you’re walking on usually belongs to the building’s owner, and the law still says you’re allowed to be there.

A Rain Shelter That Became the Law

Taiwan’s heavy rain and fierce sun made covered shopfronts a natural fit, and they were around well before 1900. During the Qing era, governor Liu Mingchuan promoted arcaded streets in Taipei’s Dadaocheng district. The Japanese colonial government then turned the habit into a requirement. In 1900 it issued the Taiwan House Building Rules (臺灣家屋建築規則), the island’s first building code, which made street-facing houses leave a covered public passage inside their own lot line. A 1903 follow-up regulated nearly everything about these walkways, including the paving, signboards, drainpipes and cleaning, and it required them to stay clear.

Private Floor, Public Path

That deal is still in force. In Taiwan a qilou is legally treated as part of the sidewalk. National road-design standards let streets 12 meters wide or narrower skip a separate sidewalk if level arcades are in place. Owners get something back for giving up the space. The arrangement traces to a 1933 rule that left walkway area out of a building’s site-coverage count, and owners who keep the arcade open can also get property-tax breaks. Even the width is set by law: Taipei’s building code fixes it at 3.64 meters.

Why Your Walk Feels Like a Staircase

In practice, every building laid its own floor at its own height. Article 43 of the Building Act says an arcade floor must not be higher or lower than the one next to it, but enforcement has been patchy. The result is the famous qilou obstacle course: a step up, a ramp down, a parked scooter, a shop’s stool spilling out. Taiwan’s papers have compared walking Tainan’s arcades to mountain climbing. Cities have spent years on leveling programs to smooth the route for strollers and wheelchairs.

A Cousin of Singapore’s Five-Foot Way

Taiwan isn’t alone. In Malaysia and Singapore the same covered walkway is called the “five-foot way” (五腳基) because British colonial rules set it at five feet wide. Together they’re part of one big family of Southern Chinese shophouse streets that spread across East and Southeast Asia.

要點： on your next rainy day in Taipei, stick to the arcades. The old commercial streets around Wanhua and Dadaocheng let you walk for blocks without opening an umbrella (our typhoon-season guide has a few favorite routes). Keep an eye out for the steps, and look up too. The second-floor windows above the arcade are where you’ll spot Taiwan’s iron flower windows, and arcades shelter whole streets like 永康街.
