In my post on Washington Street,
I speculated that Washington Street may have had different names for
different stretches of the street because house numbering was not
widely used in the 18th century. Here is the ordinance regulating
house numbering, which came into effect after Boston became a city.
An Ordinance concerning Buildings and Resevoirs in the City, and for preventing trespasses on the same. [Passed Nov. 14, 1833]
Section 2. Be it further ordained, That the Mayor and
Aldermen shall have power, (provided it can be done without expense to
the city) to cause numbers of regular series, to be affixed to or
indscribed on, all dwelling houses and other buildings erected or
fronting on any street, lane, alley, or public court within the city of
Boston, at their discretion; and shall also have power to determine the
form, size, and material of such numbers, and the mode, place,
succession and order, of inscribing or affixing them on their
respective houses or other buildings.
