Mandatory Set-Aside Ordinance. If the Borough or a Borough Land Use Board permits the construction of multi-family or single-family attached residential development, the Borough or the Borough's Land Use Board shall require that an appropriate percentage of the residential units be set aside for low- and moderate-income households. This requirement shall apply beginning with the effective date of this section to any multi-family or single-family attached residential development, including the residential portion of a mixed-use project, which consists of five (5) or more new residential units, whether permitted by a zoning amendment, a variance granted by the Borough's Land Use Board, or adoption of a Redevelopment Plan or amended Redevelopment Plan in areas in need of redevelopment or rehabilitation. For any such development for which the Borough's land use ordinances (e.g. zoning or an adopted Redevelopment Plan) already permitted residential development as of the effective date of this section, this requirement shall only apply if the Borough permits an increase in gross residential density. Nothing in this paragraph precludes the Borough or the Borough's Land Use Board from imposing an affordable housing set-aside in a development not required to have a set-aside pursuant to this paragraph consistent with N.J.S.A. 52:27D-311(h) and other applicable law. For inclusionary projects in which the low and moderate units are to be offered for for-sale or rental, the appropriate set-aside percentage is 20%. This requirement does not create any entitlement for a property owner or applicant for a zoning amendment, variance, or adoption of a Redevelopment Plan or amended Redevelopment Plan in areas in need of redevelopment or rehabilitation, or for approval of any particular proposed project. This requirement does not apply to any sites or specific zones otherwise identified in the Borough's Settlement Agreement with FSHC dated October 8, 2020, or in the Borough's Housing Element and Fair Share Plan, both of which as may be approved by the Superior Court for which density and set-aside standards shall be governed by the specific standards set forth therein.
Furthermore, this section shall not apply to developments containing four (4) or less dwelling units. All subdivision and site plan approvals of qualifying residential developments shall be conditioned upon compliance with the provisions of this section. Where a developer demolishes existing dwelling units, and builds new dwelling units on the same site, or expands an existing building, the provisions of this section shall apply only if the net number of dwelling units is five (5) or more.
