Stamford, Connecticut Zoning Districts: What Do They Mean?
Zoning districts are areas regulated by specific laws that determine land use, building types, and development rules. Each district below shows its zone type. Stamford's ordinance does not state permitted uses as citywide flags, so they are read from each district's own table rather than summarised here.
| Zone Code | Category | Area | Details |
|---|---|---|---|
RA-1 One Family Residence | - | 8,807.7 ac | Standards & uses → |
RA-3 One Family Residence | - | 3,149.2 ac | Standards & uses → |
RA-2 One Family Residence | - | 2,669.5 ac | Standards & uses → |
R-10 One Family Residence | - | 1,945.2 ac | Standards & uses → |

Stamford regulates land through 42 zoning districts, and the residential system is both large and unusually specific. One Family Residence appears in several distinct districts, coded RA-1, RA-2, RA-3, R-10, R-20 and R-7-1/2, with RA-1 the largest district in the city at roughly 8,808 acres. The fractional code in the last of these is a real designation rather than a typographical artefact.
The more distinctive feature is the Design designation. Stamford carries multiple family districts explicitly labelled by design at low, medium and high density, plus a general multiple family residence design district. It also carries combined districts pairing a one family district with a design residence district, such as one family at R-20 combined with design residence. In those combined districts a parcel sits under both designations at once, which is a genuine diligence point.
The commercial roster is compact and role-based: design commercial, neighborhood business, limited business, village commercial and a Center City district covering roughly 145 acres. Industrial splits into general and light, with general industrial at roughly 485 acres.
Park covers roughly 885 acres, the seventh largest classification. For anyone evaluating a Stamford site the two questions that matter most are which one family district applies and whether a design residence designation is combined with it. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
Stamford zoning: frequently asked questions
How many one family residence districts does Stamford have?
Several, coded RA-1, RA-2, RA-3, R-10, R-20 and R-7-1/2. RA-1 is the largest district in the entire city at roughly 8,808 acres, and the fractional code in R-7-1/2 is a genuine designation.
What does the Design designation mean?
Stamford labels several multiple family districts explicitly by design, at low, medium and high density, plus a general multiple family residence design district. The designation identifies districts where design standards form part of the framework.
What are the combined districts?
Districts pairing a one family district with a design residence district, such as R-20 combined with design residence, or RA-1 and RA-2 combined with it. A parcel in one sits under both designations at once, which is an important diligence point.
How is commercial zoning organised?
By role rather than by scale alone: design commercial, neighborhood business, limited business, village commercial, and a Center City district covering roughly 145 acres. The roster is compact relative to the residential side.
How much park land is there?
The Park district covers roughly 885 acres, making it the seventh largest classification in the city and the largest that is not residential.
