Chattanooga, Tennessee 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. Chattanooga'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 |
|---|---|---|---|
RN-1-6 Residential Neighborhood Zone 1 To 6 | - | 25,161.9 ac | Standards & uses → |
I-H Heavy Industrial Zones | - | 14,531.3 ac | Standards & uses → |
OS Open Space Zone | - | 10,378.1 ac | Standards & uses → |
RN-1-7.5 Residential Neighborhood Zone 1 To 7.5 | - | 8,419.9 ac | Standards & uses → |

Chattanooga regulates land through 79 zoning districts, and the residential codes carry two numbers: a zone level and a lot standard.
Residential Neighborhood Zone 1 appears at 3, 5, 6 and 7.5, so RN-1-6 and RN-1-7.5 are separate districts sharing a zone level but not a lot standard. RN-1-6 is the largest district in the city at roughly 25,162 acres.
That two-number convention means identifying a site as RN-1 is not sufficient; the second figure determines what applies.
The mixed use districts carry a height number instead. The Bend Commercial Mixed Use at 12, Chestnut Street Commercial Mixed Use at 12, Urban Commercial Mixed Use at 4 and Urban Industrial Mixed Use at 4 all state their intensity in the code, and two of them are named for specific places.
A Traditional Residential Neighborhood district at roughly 731 acres names the older fabric separately from the numbered zones.
Heavy Industrial is the second largest classification at roughly 14,531 acres, a very large industrial footprint, with light industrial at about 1,148.
Open Space covers roughly 10,378 acres, and an Urban Agricultural district about 117. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
