[Massplanners] A Monday ADU Question

[Amanda Keefe]

By that same logic, would any multifamily building, regardless of number of units, be eligible for an ADU as long as it is located in a district where single-family residences are also allowed?

Chris:

1)      Here's what the new regulations says is a single-family residential zoning district is:

"Single-family Residential Zoning District. Any Zoning District where Single-family Residential Dwellings are a permitted or an allowable use, including any Zoning District where Single-family Residential Dwellings are allowed as-of-right or by Special Permit."

It's anywhere they are allowed, not necessarily exclusively.

2)      In answer to your second question, here is the definition of "principal Dwelling:"

"Principal Dwelling. A structure, regardless of whether it, or the Lot it is situated on, conforms to Zoning, including use requirements and dimensional requirements, such as setbacks, bulk, and height, that contains at least one Dwelling Unit and is, or will be, located on the same Lot as a Protected Use ADU."



The principal dwelling or its lot need not be conforming. The principal dwelling must contain at least one dwelling unit, which leaves open two-family and three-family structures as qualifying for the addition of a protected use ADU under this exemption.

Here also is a link to the new regulations (which could change before the 31st, but likely won't).

Hi all

Having read the final state regs on ADUs, it still isn't clear (to me) whether:

1)      A single-family zoning district is exclusively single-family or is a district, that among other uses, allows single-family homes

2)      If a two- or three-family home in a single-family zoning district, either by-right or non-conforming, is still eligible for a protected use ADU

Any thoughts emerging on these questions?

Thanks

Chris
