760 C.M.R. 72.04
(1) To comply with M.G.L. c. 40A, § 3A, a Multi-family zoning district must allow Multi-family housing As of right, meaning that the construction and occupancy of multi-family housing is allowed in that district without the need for a special permit, variance, zoning amendment, waiver, or other discretionary approval. EOHLC will determine whether zoning provisions allow for Multi-family housing as of right consistent with the following requirements.
(b) Affordability Requirements. M.G.L. c. 40A, § 3A does not include any express requirement or authorization for an MBTA community to require Affordable units in a Multi-family housing project that is allowed As of right. It is a common practice in many cities and towns to require Affordable units in a Multi-family project that requires a special permit, or as a condition for building at greater densities than the zoning otherwise would allow. These inclusionary zoning requirements serve the policy goal of increasing affordable housing production. If affordability requirements are excessive, however, they can make it economically infeasible to construct new Multi-family housing.
1. For purposes of making compliance determinations with M.G.L. c. 40A, § 3A, EOHLC will consider an affordability requirement to be consistent with As of right zoning as long as the zoning requires not more than 10% of the units in a project to be Affordable units, and the cap on the income of families or individuals who are eligible to occupy the Affordable units is not less than 80% of area median income. Notwithstanding the foregoing, EOHLC may, in its discretion, approve a greater percentage of affordable units, or deeper affordability for some or all of the affordable units, in either of the following circumstances:
(c) Other Requirements That Do Not Apply Uniformly in the Multi-family Zoning District. Zoning will not be deemed compliant with M.G.L. c. 40A, § 3A's requirement that Multi-family housing be allowed As of right if the zoning imposes requirements on Multi-family housing that are not generally applicable to other uses. The following are examples of requirements that would be deemed to be inconsistent with As of right use:
