i. Any statutory tenant who vacates a housing accommodation without giving the landlord at least thirty days' written notice by registered or certified mail of his or her intention to vacate, shall be liable to the landlord for the loss of rent suffered by the landlord, but not exceeding one month's rent, except where the tenant has been removed or vacates pursuant to the provisions of this section. Such notice shall be postmarked on or before the last day of the rental period immediately prior to such thirty-day period.
j. (1) Nothing in this chapter shall be construed to require any person to offer any housing accommodations for rent, but housing accommodations already on the rental market may be withdrawn only after prior written approval of the city rent agency, if such withdrawal requires that a tenant be evicted from such accommodations.
