Welcome to the Town of Chelmsford's online Town Maps System. This system provides
7-day a week, 24-hour a day access to the Town's maps and records maintained at
the Assessors, Engineering, and Community Development offices. The Town of Chelmsford
provides this site to you as an interactive tool to make customized maps, find property
information, and explore the town's GIS data layers. To begin using the site, please
use the search fields above to type in the owners name, address, street or parcel-id
of the property of interest.
THE GIS IS A GENERAL PLANNING TOOL ONLY. These data represent the best efforts of
the Town of Chelmsford ("the Town" and its contractors to accurately represent the
Town's features in a Geographic Information System (GIS) database. The Town makes
no warranties, promises and/or reliability of the data whatsoever, including fitness
for a particular purpose. It should not be construed or utilized as a substitute
or replacement for actual fieldwork and verification, including but not limited
to, instrument survey, registry of deeds research, and correspondence and coordination
with the appropriate utility companies. For comments or questions regarding this
website, please contact the Town of Chelmsford Community Development Department
at (978) 250-5247.
To begin using the site, please use one or more of the search fields to the left
to type in as much information as you know about the property, such as house number,
street name (with prefix spelled out and no suffix), map & lot or owner name to
obtain a list of match records. For example, typing "S" in the Owner Last Name Field
will produce a list of all property owners with a last name starting with "S".
