April 2025 Amendments to the Building Standards Act: Impacts and Measures for Private Lodging Businesses
Updated: July 2025, 9
Hello, this is Shisui from Support Administrative Scrivener Corporation. The Building Standards Act was revised in April 2025 to ensure the safety of buildings and prevent illegal use. With the increase in the use of vacant houses and private lodging facilities, a review of regulations and adjustment of the scope of application were required. The main points of the revision are as follows.
1. Procedures for changing the use of small properties have been simplified
Details of revision: For buildings with a total floor area of 200 mXNUMX or less, it is no longer necessary to apply for building confirmation when changing the use of the building from a residence to a private lodging facility.
影響: It will be easier to start private lodgings using small properties such as old houses and vacant houses.
2. Reduction in the scope of the "No. 4 Exception"
Details of revision: Small buildings (such as two-story wooden buildings) that previously did not require structural inspections will now be subject to structural inspections in principle.
影響: Pre-construction design and inspection may take time and money. Be especially careful when building a new private lodging or expanding an existing one.
3. Compliance with energy conservation standards is now mandatory (for all new buildings)
Details of revision: All new buildings are required to comply with energy conservation standards.
影響: Energy-saving performance documents must be submitted when applying for building confirmation. Cooperation with construction companies and architects is important.
4. Strengthening penalties for illegal private lodgings
Details of revision: Strengthening on-site inspections and clarifying measures such as issuing orders to suspend operations and imposing fines on unlicensed operators.
影響: Legal operation is becoming increasingly important. Notification, signage, and compliance with fire and building codes are essential.
Measures that private lodging operators should take
✅ Consult with an architect in advance when planning a new building or renovation
✅ If the total floor area is less than 200 mXNUMX, a change of use application may not be required.
✅ Check the laws and regulations against local government ordinances
✅ Thorough record management of building safety and energy-saving performance
✅ It is also necessary to check the linkage with other laws such as fire and hygiene laws.
