But a tenants' group and a lawmaker criticise plan for random monthly testing
Public housing tenants will be required to report their monthly family income starting next year under the new rent adjustment mechanism.
Housing Authority sources said 2,000 tenants will be picked randomly every month to participate in the mailing survey. They will have to state their occupation and monthly income.
Those who fail to comply will be warned by the Housing Authority, and could have their lease terminated. The authority will do random checks on the questionnaires to ensure their accuracy.
The data collected will be used to formulate the new income index among tenants, which will be the key in determining future rent levels.
But a public housing group and a lawmaker have said the survey will inconvenience tenants.
