This bylaw is entitled the "Zoning Bylaw of the Town of Lexington, Massachusetts."

This bylaw has been adopted to govern uses of land; the size, height, bulk, location and use of structures, buildings and signs; and for all of the other purposes set forth in, but not limited by, Section 2A of Chapter 808 of the Acts of 1975. It is the intent of the Town of Lexington that zoning requirements within the Town encourage diversity and equity among Town residents and do not discriminate against any person or group on the basis of race, ethnicity, religion, gender, sexuality, ability, or any other basis prohibited by federal or state law, and further that any ambiguities in the bylaw be interpreted with this intent in mind.

This bylaw is enacted under the authority of MGL c. 40A, as amended, and by the Home Rule Amendment, Article 89 of the Amendments to the Constitution of the Commonwealth of Massachusetts.

The use, construction, repair, alteration, height, location, percentage of site coverage of buildings and structures, and land in the Town of Lexington are regulated as described in this bylaw. No building, structure, or land may be used or occupied and no building, structure, or part thereof, may be erected, constructed, reconstructed, moved, or structurally altered unless in conformity with the regulations of this bylaw.

Amendments to this bylaw must be made in conformance with MGL c. 40A, § 5.

The invalidity of any section or provision of this bylaw does not invalidate any other section or provision of it.
