Planning Forms & Regulations

Zoning Bylaw & Map

Zoning is the principal way the Town regulates the use of land within its borders. The Bylaw consists of two parts, the text and the map; both are available below.

  • The Zoning Bylaw — A digital version of the Town's code that can be accessed and searched quickly. Hard copies of the Bylaw are available for purchase in the Planning Office.
  • The Zoning Map — updated through Town Meeting 2016.  Hard copies are available for purchase in the Planning Office.

Development Regulations

Lexington's Development Regulations provide procedures and standards for developing and/or dividing parcels of land into smaller parcels for development. Please note that the digital code has yet to incorporate these changes.  The files above should be used until they are incorporated into the Town's Code.
