Connecticut Zoning Initiative

Posted on

Welcome to the Connecticut Zoning Initiative, a website with data on residential land-use regulations for municipalities across the state. This page includes a scrollable “card view” listing data for each town, a link to a full spreadsheet with data for all towns in Connecticut, a link to the definitions used for this project, a place to provide comments, and several maps illustrating the potential power of the data.

The goal of this collaborative effort between the Connecticut Fair Housing Center and the Cities Suburbs & Schools Project at Trinity College is to promote smart, fair and effective land-use policy by collecting and presenting accurate town-by-town zoning data. Information is current as of May 2013, unless otherwise stated, and based on definitions as described below.

(Click on any town for more details.)

Map 3: Multifamily Housing Permitted shows whether a town’s zoning regulations allow multifamily housing of three or more units, and if so, whether the zoning regulations require a special permit or if they allow multifamily housing by right. (Click on any town for more details.)
