Hartford, 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. Hartford'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 |
|---|---|---|---|
OS Open Space | - | 2,264.4 ac | Standards & uses → |
MX-2 Multi Use Mix 2 | - | 1,314.7 ac | Standards & uses → |
ID-1 Industrial 1 | - | 1,224.6 ac | Standards & uses → |
NX-1 Neighborhood Mix 1 | - | 768.5 ac | Standards & uses → |

Hartford regulates land through 29 zoning districts under a form-based framework, and the codes carry two numbers rather than one. A neighborhood district appears as N followed by an intensity number and then a second number, so N-2-1, N-2-2 and N-2-3 are three distinct districts sharing an intensity band.
That second number is the key to reading the map. Districts within the same band differ in their standards, so identifying only the band is not enough for diligence: the full code determines what applies.
By area the largest classification is Open Space at roughly 2,264 acres, ahead of every development district. Multi Use Mix 2 follows at about 1,315 acres and Industrial 1 at roughly 1,225. Neighborhood Mix 1 and 2 together cover over fourteen hundred acres.
The Main Street family, numbered 1 through 3, covers the city's commercial corridors, and a Downtown district covers the core. Commercial And Industrial Mix appears in two versions, which is a useful category in a city with substantial legacy industrial fabric close to residential neighborhoods. Industrial is split into two districts.
The practical reading is that Hartford's code is granular by design and the full district code, including both numbers, is the unit that matters. Hartford regulates building height, coverage, density, floor area ratio, lot size and width, pervious area, and front, side and rear setbacks. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
Hartford zoning: frequently asked questions
Why do Hartford district codes have two numbers?
The first marks the intensity band and the second distinguishes districts within it. N-2-1, N-2-2 and N-2-3 are three separate districts sharing a band but not sharing standards, so the full code rather than the band determines what applies.
Which is the largest district in Hartford?
Open Space, at roughly 2,264 acres, ahead of every development district. Multi Use Mix 2 follows at about 1,315 acres and Industrial 1 at roughly 1,225.
What is the Main Street family?
Three districts numbered 1 through 3 covering the city's commercial corridors. They regulate the form of development along those streets rather than sorting uses, consistent with the rest of Hartford's form-based framework.
What is the Commercial And Industrial Mix district?
A district that appears in two versions, together covering over four hundred acres. It is useful in a city where legacy industrial fabric sits close to residential neighborhoods, since it addresses the combination rather than forcing a separation.
How much of Hartford is mixed use?
Multi Use Mix 1 and 2 together cover roughly fifteen hundred acres, and Neighborhood Mix 1 and 2 add over fourteen hundred more. Mixed categories account for a large share of the city's developable land.
