Naperville, Illinois 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. Naperville'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 |
|---|---|---|---|
R1A Low Density Single Family Residence District | - | 6,990 ac | Standards & uses → |
R1A-PUD Low Density Single Family Residence District Planned Unit Development | - | 1,667.5 ac | Standards & uses → |
R1 Low Density Single Family Residence District | - | 1,377 ac | Standards & uses → |

Naperville regulates land through 40 zoning districts, and the organising mechanism is the planned unit development suffix. Most base districts also exist in a PUD version, so low density single family, medium density single family, low density single and multiple family, medium density multiple family, high density multiple family, community shopping center and office commercial institutional all appear both plain and planned.
The planned versions are substantial. The PUD variant of the low density single family district covers roughly 1,668 acres, the second largest classification in the city, and the medium density single family PUD covers about 1,063.
For diligence the suffix is the first thing to establish, because it determines whether the citywide tables or an approved plan sets the standards for a site.
The residential ladder itself is clearly named by density and housing type: low density single family, medium density single family, low density single and multiple family, and medium and high density multiple family. Low Density Single Family Residence coded R1A is the largest district in the city at roughly 6,990 acres.
Two estate districts, at low and medium density, cover roughly 925 acres. An Office Research Light Industrial district covers about 791 acres, and a general Industrial district roughly 1,310. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
Naperville zoning: frequently asked questions
What does the PUD suffix mean in Naperville?
That the district exists in a planned unit development version alongside the plain one. In the PUD version an approved plan sets the standards rather than the citywide tables, so the suffix determines which document governs a site.
How large are the planned versions?
Substantial. The PUD variant of the low density single family district covers roughly 1,668 acres, the second largest classification in the city, and the medium density single family PUD covers about 1,063 acres.
Which is the largest zoning district?
The low density single family residence district coded R1A, at roughly 6,990 acres, more than four times the next largest classification.
How are residential districts named?
By density and housing type together: low density single family, medium density single family, low density single and multiple family, and medium and high density multiple family. Two estate districts at low and medium density sit below them.
What employment districts does Naperville have?
An Office Research Light Industrial district at roughly 791 acres, a general Industrial district at about 1,310, and an Office Commercial Institutional district in both plain and planned versions covering roughly 463 acres together.
