In order to insure continuous compliance with the age restrictions, each contract of sale or lease agreement for the varying housing types within the development will require certification of the household composition, i.e., the name and birth date of each resident. Each household shall recertify its composition (i.e., the name and birth date of each resident) on an annual basis. The entity with management responsibilities or the homeowners' association for the development shall submit, on an annual basis, to the Director of Planning and Growth Management a letter certifying and documenting the composition (i.e., the name and birth date of each resident) and compliance of each household in the development.
