Amendments to the Zoning By-Law or Zoning Map are voted on by Town Meeting. Proposals for amendments can be submitted as warrant articles. Town Meeting is held typically twice a year, once in May and again in November. The open warrant period usually begins in February for the spring Town Meeting and in August for the fall Town Meeting. Warrant articles must be submitted to the Select Board's Office before noon on the day the Warrant closes. Warrant articles submitted by citizens must be accompanied by 10 signatures of Brookline registered voters. It is recommended that proposed amendments be submitted to Town Counsel for prior review to ensure issues of legality or form are addressed. For more information on this process, read this guide.
