Dover, New Hampshire 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. Dover'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 |
|---|---|---|---|
R-40 Rural Residential | - | 9,177 ac | Standards & uses → |
R-12 Medium Density Residential | - | 2,580.1 ac | Standards & uses → |
R-20 Low Density Residential | - | 2,135.7 ac | Standards & uses → |
IT Innovative Technology | - | 1,458 ac | Standards & uses → |

Dover regulates land through 18 zoning districts, and the central business district is split four ways: general at roughly 165 acres, mixed use at about 29, residential at roughly 23 and transit oriented development at about 18.
Dividing a downtown that size into four designations, including a dedicated transit oriented district, is fine-grained planning for a city of this scale and shows exactly what the city intends in each part of the core.
The waterfront carries two named districts: Cochecho Waterfront at roughly 102 acres and Little Bay Waterfront at about 89. Naming each body of water separately rather than applying one waterfront designation recognises that a river frontage and a bay frontage raise different questions.
The Innovative Technology district at roughly 1,458 acres is the fourth largest classification, a substantial commitment to a named employment sector.
The residential codes state lot size: R-12 medium density, R-20 low density and R-40 rural, with the rural district the largest in the city at roughly 9,177 acres. Multi residential appears in suburban and urban density versions covering roughly 955 acres between them.
A Heritage Residential district covers roughly 134 acres and a Gateway district about 283. A Hospital district covers roughly 37 acres. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
