Regarding the period for which landlords of rental housing treated under this grant program must give priority to families with a child under age 6, applicants should disregard Section I.A.1.2.8, on page 2, because it is superseded by Section III.F, bullet #1, on pages 25-26. Specifically, page 2’s “up to three years” is superseded by page 26’s “not less than 3 years” (in “the landlord shall give priority in renting units assisted under this section, for not less than 3 years following the completion of lead abatement activities, to families with a child under the age of six years”), which is from the law (Title X) establishing this grant program.
