It is the responsibility of the municipal housing liaison and the administrative agent(s) to ensure that affordable housing units are administered properly. All affordable units must be occupied within a reasonable amount of time and be re-leased within a reasonable amount of time upon the vacating of the unit by a tenant. If an administrative agent or Municipal Housing Liaison becomes aware of or suspects that a developer, landlord, or property manager has not complied with these regulations, it shall report this activity to the Division. The Division must notify the developer, landlord, or property manager, in writing, of any violation of these regulations and provide a 30-day cure period. If, after the 30-day cure period, the developer, landlord, or property manager remains in violation of any terms of this subchapter, including by keeping a unit vacant, the developer, landlord, or property manager may be fined up to the amount required to construct a comparable affordable unit of the same size and the deed-restricted control period will be extended for the length of the time the unit was out of compliance, in addition to the remedies provided for in this section. For the purposes of this subsection, a reasonable amount of time shall presumptively be 60 days, unless a longer period of time is required due to demonstrable market conditions and/or failure of the municipal housing liaison or the administrative agent to refer a certified tenant.
