An individual who is employed as a domestic worker in a private home is a covered employee with respect to a household if the individual earns at least $1,000 in cash in a calendar quarter from that household. Except as provided in paragraph (3) of this subsection, an individual and the employer of the individual may elect to make the individual a covered employee by filing a joint election with the Commission, if the individual: is employed as a domestic worker in a private home; and would not be a covered employee with respect to a household under the provisions of subsection (a) of this section because the individual earns less than $1,000 in cash in a calendar quarter from that household. The right to make an election under paragraph (1) of this subsection for an individual may be exercised by: an individual who is at least 16 years old; or a parent or guardian of an individual who is less than 16 years old. For an individual who is not a covered employee due to § 9–223(c) of this subtitle, an employer may not make an election under this subsection if prohibited by federal law.
