Why the Minpaku Act Makes Notification So Much Easier: The Advantage of Avoiding “Special Building” Classification Under the Building Standards Act

When property owners try to launch a lodging business using a vacant house or older property, many run headfirst into the strict requirements of the Hotel Business Act. Issues like “the zoning doesn’t allow it” or “a change-of-use building application is required” frequently bring these plans to a grinding halt.

However, even for properties that can’t be turned into a hotel or inn, there’s still a legal path to operating them as lodging facilities.

Let’s get straight to the conclusion of this article.

Ordinary hotels and inns are classified as “special buildings” under Japan’s Building Standards Act, which means converting an existing residence into one requires an extremely strict legal compliance review (a change of use). However, by using the Private Lodging Business Act (the “Minpaku Act”), the building continues to be treated as an ordinary “residence”—meaning no change-of-use process to a special building is needed. This lets you avoid massive renovation costs and complicated administrative procedures, allowing you to launch a lawful minpaku business quickly and efficiently.

In this article, we’ll take a deep dive into what exactly a “special building” is and why it stands in the way of entering the lodging business, how the Minpaku Act legally sidesteps this barrier, and just how much difference these regulatory distinctions can make to your initial investment.

The High Wall of “Special Buildings” Blocking the Path to a Lodging Business

Whenever someone tries to convert an ordinary house into a hotel or inn, they inevitably run into the wall of the Building Standards Act. And the biggest obstacle within it is the concept of the “special building.”

What Is a “Special Building”?

Under the Building Standards Act, hotels, inns, hospitals, schools, movie theaters, and similar facilities are designated as “special buildings.” Because these are facilities “used by an unspecified large number of people” or that “involve overnight stays,” they’re subject to far stricter safety standards than ordinary homes—fireproof construction, secured evacuation routes, restrictions on interior materials, and more—to ensure that even guests unfamiliar with the building can safely evacuate in the event of a fire or earthquake.

The Difficulty of “Change of Use” and the Certificate of Inspection Problem

When a property originally built as a “single-family house” or “office building” is to be operated as a hotel or simple lodging under the Hotel Business Act, a “change of use” procedure is required to reclassify the building as a “special building” (hotel/inn).

During this change-of-use process, the building must be checked for compliance with current, stricter Building Standards Act requirements. With older properties, the “certificate of inspection” that proves the building was legally compliant when originally constructed is often missing—and without it, the change-of-use application won’t even be accepted. As a result, owners are left with only two options: spend a fortune on major renovations, or abandon the project altogether.

Why Can the Minpaku Act Rely on a Simple Notification? The Huge Advantage of Being Treated as a “Residence”

What freed properties from the grip of “special building” classification—and opened the door to putting vacant homes to use—was the Private Lodging Business Act (the “Minpaku Act”), which took effect in 2018.

No “Change of Use” Required Under the Building Standards Act

The Minpaku Act’s biggest advantage—and the heart of its legal mechanism—is this: when guests are accommodated under the Minpaku Act, the building continues to be treated as a “residence” under the Building Standards Act.

Because the arrangement is framed as “a home where people live, temporarily lent out to travelers,” there’s no need to go through the change-of-use process to convert it into a “hotel/inn” as a special building.

Since no change of use is required, you also avoid the need for large-scale renovation work to bring the building up to current, stringent Building Standards Act requirements, and you won’t be asked whether a certificate of inspection exists. All that’s needed is to submit a “notification” to the prefectural governor (or equivalent authority) along with the required documents, and you can legally launch your lodging business.

Sidestepping Zoning Restrictions

Under Japan’s City Planning Act, land throughout the country is divided into zones—for example, “only residences may be built in this area” or “commercial facilities are permitted here” (known as “use zoning” or yōto chiiki).

Hotels and simple lodges operating under the Hotel Business Act generally cannot operate in quiet residential zones such as “Category I Low-Rise Exclusive Residential Zones” or “Category I Mid/High-Rise Exclusive Residential Zones.”

However, because the Minpaku Act treats the building as a “residence,” in principle minpaku operations are permitted in virtually all use zones. (Note: some municipalities may impose their own ordinances limiting operating days or periods.)

This means a property with a fantastic location that could never become a hotel due to zoning restrictions can suddenly be transformed into a “money-making asset.”

The “Cost” and “Time” You Save by Avoiding Special Building Status

By leveraging the Minpaku Act and avoiding the change of use to special building status, you gain overwhelming advantages during the early stages of your business.

Cutting Renovation Costs by Millions of Yen

Converting a property to special-building status through a change of use requires costly work such as widening staircases, installing emergency lighting, and replacing wall and ceiling materials with non-combustible alternatives.

With the Minpaku Act, none of this “construction work to comply with the Building Standards Act” is necessary, allowing you to cut your initial investment by potentially millions of yen. You can redirect those savings toward more stylish interior design or higher-end furniture and appliances, boosting guest satisfaction (and reviews) and enabling you to charge higher nightly rates.

*That said, even though no change of use is required under the Building Standards Act, installing fire safety equipment required under the Fire Service Act (such as automatic fire alarms and emergency exit lights) is still mandatory, so be sure to budget for this.

A Faster Launch by Skipping Bureaucratic Red Tape

Obtaining a Hotel Business Act license requires complex prior consultation and review across multiple government bodies—public health centers, fire departments, building administration divisions—and it’s not unusual for the process to take six months or more before opening.

The Minpaku Act, on the other hand, operates on a “notification” system. Once you’ve set up the required facilities (kitchen, bathroom, toilet, and washroom) and obtained items such as a fire safety compliance notice, you can submit your application and typically receive your acceptance notice within a relatively short period—about one to two months—allowing you to start operating right away. Minimizing wasted time on rent or loan payments and quickly generating cash flow is a major advantage.

Overcoming the Minpaku Act’s Downside: The “180-Day Rule”

We’ve covered the benefits of the Minpaku Act so far, but of course, there are downsides too. The biggest one is the rule capping annual operating days at 180.

As the trade-off for avoiding the special-building hurdle, you’re limited to operating for only half the year. However, with the right operational strategy, this constraint can be fully offset.

A Hybrid Approach with Monthly Rentals

The most powerful strategy for overcoming the 180-day limit is a hybrid model combining minpaku operations with a “monthly rental” (fixed-term lease) arrangement.

During peak seasons—cherry blossom and autumn foliage seasons, the New Year holidays, major long weekends—when inbound demand surges and nightly rates climb, you operate the property as a minpaku, efficiently using up your 180-day allowance.

Then, during the off-season or once you’ve hit your annual limit, you switch to renting the property out on a monthly basis. Since monthly rentals fall under a standard lease agreement, they don’t count toward the 180-day cap. This approach lets you keep the property running at full capacity year-round, maintaining a strong overall yield.

Conclusion: Understand the Regulations and Invest in Minpaku Wisely

When it comes to putting vacant houses or older properties to use, correctly understanding the difference between the Hotel Business Act and the Minpaku Act is one of the most critical factors determining whether your investment succeeds.

1. Obtaining a license under the Hotel Business Act requires clearing the high hurdle of a change of use to “special building” status.
2. Under the Minpaku Act’s notification system, the building continues to be treated as a “residence,” so no change of use is required.
3. You can significantly cut your initial investment while maximizing revenue through a hybrid operating model.

Properties you may have given up on because “they can’t get a Hotel Business Act license” could, when viewed through the lens of the Minpaku Act, hold the potential to become a hidden goldmine of profit.
