Residential (R) Districts

The Residential Districts are meant to accommodate a variety of residential dwellings at a scale of densities, including one- and two-unit homes and multi-unit homes. These districts are also meant to accommodate agricultural uses, as well as limited additional uses that complement and enhance residential uses, such as parks, libraries, churches, and opportunities for compatible home-based businesses. 

Residential-7 (R-7)

The R-7 zoning district encompasses the densest residential area that surrounds the mixed-use core of historic Mystic Village. The area is covered by the Mystic River Historic District, and buildings, existing and new, must adhere to historic district design standards. Dimensions in this district are designed to encourage one- and two-unit dwellings that support the denser, historic residential patterns of Mystic Village.  The minimum lot size is 7,000 SF.         

Residential-12 (R-12)

The R-12 district encompasses residential neighborhoods throughout the Town, from mid-century ranches and split levels, to modest one- and two-unit homes around Midway Oval, to some of the military housing along the Thames River. What these diverse neighborhoods share in common are generally smaller lots, often walkable and bikeable internally and to nearby resources. Future development and redevelopment in this zoning district will enhance these benefits by encouraging one- and two-unit dwellings in walkable, bikeable, sewered, residential neighborhoods near or adjacent to mixed-use centers, other retail and services, parks, schools, and major roads and transit. The minimum lot size is 12,000 SF.

Residential Single-Unit-12 (RS-12)

The RS-12 district encompasses residential neighborhoods throughout the Town, from portions of the Mystic River Historic District, to mid-century ranches and split levels of the Bel-Aire and other neighborhoods, to newer subdivisions. What these diverse neighborhoods share in common are generally smaller lots, often walkable and bikeable internally and to nearby resources. Future development and redevelopment in this zoning district will enhance these benefits by encouraging one-unit dwellings in walkable, bikeable, sewered, residential neighborhoods near or adjacent to mixed-use centers, other retail and services, parks, schools, and major roads and transit. The minimum lot size is 12,000 SF.

Residential Single-Unit-20 (RS-20)

The RS-20 district is found throughout the Town, and is designed to encourage one-unit dwellings in more traditional suburban settings.  Open Space Subdivisions are encouraged in this district, as much of the remaining undeveloped land within the district is considered wetlands. To date, use of the Open Space Subdivision provisions has been successful in clustering new subdivision development in order to preserve neighboring environmentally sensitive lands, and this trend should continue. When adjacent to an R-12 or RS-12 district, new development in the RS-20 district should strive to mirror the connectivity of the R-12 or RS-12 district, extending existing streets, sidewalks, and bicycle networks, to expand options and livability for residents. The minimum lot size is 20,000 SF.

Rural Residential-20 (RU-20)

The RU-20 district is found throughout the Town, and is designed to encourage one- and two-unit dwellings in more traditional suburban settings.  Open Space Subdivisions are encouraged in this district, as much of the remaining undeveloped land within the district is considered wetlands. To date, use of the Open Space Subdivision provisions has been successful in clustering new subdivision development in order to preserve neighboring environmentally sensitive lands, and this trend should continue. When adjacent to an R-12, RS-12 or RS-20 district, new development in the RU-20 district should strive to mirror the connectivity of the adjacent district, extending existing streets, sidewalks, and bicycle networks, to expand options and livability for residents. The minimum lot size is 20,000 SF.

Rural Residential-40 (RU-40)

The RU-40 district is located largely to the north of I-95, and covers the majority of remaining developable land in the Town. This district is meant to accommodate one-unit dwellings, agriculture and related activities, and other lower-density uses. As with the RS-20 and RU-20 districts, much of the undeveloped RU-40 district is considered wetlands, so Open Space Subdivisions will continue to be a useful tool in protecting sensitive environmental areas.  New developments adjacent to existing Open Space Subdivisions should strive to connect open spaces in order to maintain a network of open space and habitat, rather than isolated pockets. The minimum lot size is 40,000 SF.

Rural Residential-80 (RU-80)

The RU-80 district is located entirely to the north of I-95. Like the RU-40 district, the RU-80 district is meant to accommodate one-family dwellings, agriculture and related activities, and other lower-density uses. Likewise, some of the undeveloped RU-80 district is considered wetlands, so Open Space Subdivisions will continue to be a useful tool in protecting sensitive environmental areas as well as currently unprotected open space.  New developments adjacent to existing Open Space Subdivisions should strive to connect open spaces in order to maintain a network of open space and habitat, rather than isolated pockets. The minimum lot size is 80,000 square feet.

Residential Multi-Unit (RM)

The RM district is scattered, with most sites on the western half of the Town.  The vast majority of RM parcels are already built out with existing multi-unit homes, ranging from side-by-side town houses to stacked garden apartments, and including both rentals and ownership condominiums. The RM district is meant to encourage and guide the development of multi-unit projects within the Town where necessary utilities and transportation improvements are in place. It is designed to accommodate all allowable residential-only developments of three housing units or more.
