(1) In units occupied by families with children of less than 6 years of age and in common areas servicing those units, interim controls shall be completed no later than 90 days after the completion of the risk assessment. In units in which a child of less than 6 years of age moves in after the completion of the risk assessment, interim controls shall be completed no later than 90 days after the move-in.

(2) In all other dwelling units, common areas, and the remaining portions of the residential property, interim controls shall be completed no later than 12 months after completion of the risk assessment for those units.

Effective immediately after completion of the risk assessment required in § 35.715(a), the owner shall incorporate ongoing lead-based paint maintenance and reevaluation into the regular building operations in accordance with § 35.1355, unless all lead-based paint has been removed. If the reevaluation identifies new lead-based paint hazards, the owner shall conduct interim controls in accordance with § 35.1330.

(d) Transitional requirements—(1) Effective date. The requirements of this paragraph shall apply effective September 15, 2000, and continuing until the applicable date specified in § 35.715(a) (1) or (2) or until the owner conducts a risk assessment, whichever is first.
