Kawasaki City in Kanagawa Prefecture is planning to introduce guidelines to limit the construction of small studio apartments. The city has seen a surge in development of ‘one-room’ apartment buildings and is concerned about the effects on local communities.
The new guidelines may increase the minimum apartment size from 18 sqm (194 sq.ft) to 25 sqm (269 sq.ft), and may require on-site building managers or caretakers. For a building with over 100 units, an on-site manager may be required, while smaller buildings may require a manager for a minimum set of hours per day or week. Garbage collection may be required daily. Developers, managers and residents may also be encouraged to join the local neighbourhood association. However, there will be no fines or penalties for failure to comply with the guidelines.
