ACCESSORY APARTMENT COMMITTEE
REPORT TO THE TOWN MEETING UNDER ARTICLE 2 APRIL 5, 1982
Article 64 of the 1979 Annual Town Meeting and Article 62 of the
1980 Town Meeting were Planning Board articles proposing a change
in the Zoning By-law to allow accessory apartments in single fam-
ily houses in RO and RS Residential Zones, with specific limita-
tions, and subject to issuance of a Special Permit by the Board
of Appeals Both were turned down by the Town Meeting In both
cases, the vote in favor of the zoning change was large, but not
the necessary 2/3 vote (105 to 63 in 1979; 107 to 69 in 1980)
The acknowledged existance of an unknown number of unauthorized,
and therefore illegal apartments in single family residential
zones, coupled with a lack of information concerning the number
of single family houses eligible for conversion under the pro-
posed limitations were factors contributing to the negative votes.
In 1981, the Annual Town Meeting authorized the appointment by the
Board of Selectmen of an "Accessory Apartment Committee" to study
the whole problem, and to report back to the 1982 Town Meeting.
The original motion authorized only a study of the existing il-
legal apartment situation; but it was amended to include a study
of a possible zoning change to allow new accessory apartments
On October 6, 1981, the Selectmen appointed a 5 member committee
Steven Clark, Chairman; Cornelius Cronin; Jean Gaudet; George
McCormack; and Margaret Rawls. The charge given to the committee,
adopted by the Selectmen on August 3, 1981, was
"The Committee shall review past and present proposals regarding
the existing disposition of accessory apartments within the Town
of Lexington and propose recommendations to the Board of Select-
men regarding any recommended changes in the existing situation
for accessory apartments and also recommend a course of action
regarding future accessory apartments within the Town of Lexing-
ton. The Committee shall report back to the Board of Selectmen
no later than January 1, 1982" .
The Committee agreed to define an accessory apartment as "a sepa-
rate and complete living unit within a single family residence
and subordinate to the main living unit"
Between its first meeting on November 3 and mid-January, the
Committee met almost weekly, beginning the study with a review of
the Zoning By-law, of past proposals by the Planning Board, and
of several accessory apartment By-laws and accompanying commen-
taries from other communities and from MAPC. The Planning Board
proposals and other town's by-laws were useful in that they
covered most of the possible arguments for and against allowing
accessory apartments, and most of the possible conditions a town
might impose on their legalization. None, however, addressed
the special problem posed by existing, illegal apartments that
hale been in use for years, but that might not meet the often
very limiting proposed conditions. The Committee decided that
to confront and try to solve that problem, we would need as
much information as could be obtained regarding the number and
location of existing apartments in RO and RS zones, the age and
the size of the houses containing them, and if possible, the age
of the apartment itself, as any apartment existing before Lexing-
ton introduced its first zoning by-law in 1924 would automati-
cally be legal.
Dave Stusse, our Town Assessor agreed to obtain as much of the
needed information as possible from the computer files of the
firm responsible for the Town' s recent appraisal. He obtained a
print-out of data about all houses containing known apartments,
many of which are in 2 family zones, but 186 of which are in single
family zones He also obtained a print-out of 93 single family
houses known to have two kitchens. Some of the latter do not con-
tain apartments. Some others have apartments not in use as such
at present. Discussions with residents of many neighborhoods
have led the Committee to believe that there are numerous other
apartments not known to the appraisers. An effort to locate some
of these by a search of the Assessor' s card files for the 10% of
the Town' s houses not entered by the inspectors was not very fruit-
ful. All known apartments were mapped, and information regarding
age of house, lot size and house size has been compiled
While reviewing the print-outs and the card files, the Committee
also met with the Town Manager, Assessor, Building Inspector,
and a member of the Board of Appeals, and held several conver-
sations with the Planning Director. The present illegal apart-
ment situation was discussed, and the implications of various
approaches to legalizing apartments in single family zones
The Zoning By-law already permits conversion to a 2 family dwell-
ing, so long as each unit is at least 700 square feet in size.
The Board of Appeals, however, has interpreted this to refer only
to a more or less equal division of a house, and not to an apart-
ment unit subordinate to the main unit. The Committee, on the
other hand, agrees that any house with two complete living units
is a 2 family dwelling, and that the present by-law does allow
permits for apartments over 700 square feet in size. We also
agree, however, that smaller units are often desireable, and that
there must be more control over apartment conversions than is
afforded by the present by-law.
The Committee has compiled a list of arguments in favor of legal-
O
Ft
ization of accessory apartments, to guide us in weighing the ad-
vantages and disadvantages of various limitations and conditions
We have also prepared a preliminary list of conditions that would
have to be met by anyone wishing to construct an accessory apart-
ment. To test for the possible number of houses that could
qualify under various lot and house size limitations, we request-
ed a print-out containing various cross-referenced indicators
(for instance, all houses of a stated minimum size on lots of a
stated minimum size) . Information has not been programmed to give
such cross referenced results, so the Committee has recently ob-
tained and is now analyzing a print-out of all the single family
houses in RO and RS districts, a formidable task.
The Committee requested a place for an article in the Warrant for
the 1982 Annual Town Meeting, but soon determined that time did
not allow preparation of an article with all the back-up material
and justification we think it desireable to present to Town Meet-
ing. Our present view is that a by-law change to allow accessory
apartments is warranted; but we hope to obtain more information
about possible impact on the Town before determining what condi-
tions new apartments should meet, and what special rules, if any,
should apply to existing apartments. We also wish to have further
discussions with the Board of Appeals concerning their possible
role in the approval process. Our intention is to prepare an
article before the Warrant closes in December 1982, if information
gathered in the interim does not cause us to alter our course
We would appreciate any help Town Meeting members and others can
give us in locating existing accessory apartments We hope to
provide a mechanism for legalization of those that either meet
the conditions proposed for new apartments, or meet a combina-
tion of other conditions.
We have tried to keep the Town Meeting members and the Select-
men informed, sending reports of our activities to the TMMA
Newsletter and copies of our minutes to the Selectmen. We shall
attempt to continue to keep them informed, and welcome attend-
ance at our meetings, the time and place of which is posted on the
Town Office Building bulletin board.
