Deed restriction period. Pursuant to UHAC, the redeveloper shall have an obligation to deed restrict the affordable units in the inclusionary development as very-low-, low- or moderate-income affordable units for a period of at least 30 years from the date of the initial occupancy of each affordable unit (the "deed restriction period") until the Township of Scotch Plains takes action to release the controls on affordability, so that the Township may count each affordable unit against its obligation to provide family for-sale affordable housing. The affordability controls shall not expire until such time, at least 30 years from the date of initial occupancy, that the Township takes action to release the controls on affordability. In the event that the affordable units are rental units, the affordability controls shall not expire until such time, at least 30 years from the date of initial occupancy, that the Township takes action to release the controls on affordability, and thereafter the affordability controls shall continue in effect until the date on which the individual affordable rental unit shall become vacant, provided that the occupant household continues to earn a gross annual income of less than 80% of the applicable median income. See N.J.A.C. 5:80-26.11(b). If, at any time after the release of the affordability controls by the Township, a rental household's income is found to exceed 80% of the regional median income, the rental rate restriction shall expire at the later of either the next scheduled lease renewal or 60 days. The term "family for-sale" in the redevelopment plan means for-sale units that are not age-restricted.
