On January 27, 2014, the Board voted to clarify the definition of “townhouse” to be consistent with all State Building Codes, thereby incorporating the definition of “townhouse” from 780 CMR.  Therefore, "townhouses" shall be defined as "a single-family dwelling unit constructed in a group of three or more attached units in which each unit extends from foundation to roof and with a yard or public way on not less than two sides."

The Architectural Access Board is aware of the difficulty in complying with the literal language of Section 10.3 when it is not known who the occupants of dwelling units will be prior to construction. Therefore, it is the Board's opinion that when designing and laying out parking lots reserved for tenants of multiple dwellings, when fifteen or more spaces are provided the number of accessible parking spaces provided shall be determined by Section 23.2.1 (Formula for Required Minimum Number of Accessible Spaces) of 521 CMR at the time of initial construction. When less than fifteen spaces are provided, a minimum of one accessible parking space must be capable of being provided. The AAB will be amending its regulations in the future, however, in the interim, compliance with Section 23.2.1 will satisfy Section 10.3 of 521 CMR in regards to the number of accessible parking spaces to be allotted for dwelling unit occupants.

This interpretation was unanimously accepted by the Board Members on April 8, 2006.
