ローカルのコミュニティ掲示板サイトに投稿してみたところ、つぎのような返事があった。まずはこれ。
NY State Attorney General website:
"Landlords of buildings with three or more apartments must keep the apartments and the buildings' public areas in "good repair" and clean and free of vermin, garbage or other offensive material. Landlords are required to maintain electrical, plumbing, sanitary, heating, ventilating systems and appliances landlords install, such as refrigerators and stoves in good and safe working order. Tenants should bring complaints to the attention of their local housing officials. (Multiple Dwelling Law (MDL) §78 and §80; Multiple Residence Law (MRL) §174. The MDL applies to cities with a population of 325,000 or more and the MRL applies to cities with less than 325,000 and to all towns and villages.)"
大家に修理の義務があることはまちがいないが、支払いに関して明記してない、と思っていると、まさにピンポイントの答えが返ってきた。
"Rent stabilization allows a landlord to replace with a like unit, if they have to put in a new one they can charge you 1/40 per month.
If your apartment is NOT rent stabilized the landlord cannot change the terms of the lease (increase the rent) until the lease expires."
と、いうことは10ドル(だけの)値上げというのは逆に良心的ということになる。いや〜、勉強になりました。ニューヨークに住む皆さんも参考にしてください。
