Westminster, Colorado 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. Westminster'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 |
|---|---|---|---|
PUD Planned Unit Development | - | 13,978.9 ac | Standards & uses → |
O-1 Agricultural And Open District | - | 4,065.6 ac | Standards & uses → |
R-1 One Family Residential | - | 820.4 ac | Standards & uses → |
R-A One Family Residential | - | 510.7 ac | Standards & uses → |

Westminster regulates land through 34 zoning districts, and one covers most of the city: Planned Unit Development at roughly 13,979 acres, more than three times the next largest classification. An Agricultural And Open district follows at about 4,066 acres.
That concentration means the citywide district tables govern comparatively little of Westminster. In a planned unit development the standards come from the approved plan for that project, so the entitlement record rather than the ordinance is the operative document for most sites.
The conventional districts underneath are small and conventional: three one family residential districts, a two family district, multiple family at low and high density, a mobile home district, plus commercial, business, industrial and transitional districts. None exceeds a thousand acres.
The distinctive element is the Westminster Station Area Specific Plan family. Several districts carry that designation as a suffix, and some go further by writing a floor area ratio range directly into the district code, distinguishing a station core at one range from a station core at another. Industrial, commercial and high density multifamily all appear in station area variants, alongside a transitional mixed use and a commercial mixed use version. These districts are small, together covering under a hundred acres, but they are the most specific instruments on the map and they show exactly where the city intends transit-oriented intensity. This is pre-development intelligence, not legal advice - verify with the local planning department before acquisition.
Westminster zoning: frequently asked questions
How much of Westminster is planned unit development?
Roughly 13,979 acres, more than three times the next largest classification. Most of the city is therefore governed by approved project plans rather than by the citywide district tables.
What is the Westminster Station Area Specific Plan?
A designation applied as a suffix to several districts covering the station area. Industrial, commercial and high density multifamily all appear in station area variants, alongside transitional mixed use and commercial mixed use versions.
Why do some district codes contain floor area ratio numbers?
Because the station area districts write the intended intensity directly into the code, distinguishing a station core at one floor area ratio range from a station core at another. The number is part of the district identity rather than a separate standard to look up.
What conventional districts does Westminster keep?
Three one family residential districts, a two family district, multiple family at low and high density, a mobile home district, plus commercial, business, industrial and transitional districts. None of them exceeds a thousand acres.
What is the Agricultural And Open district?
The second largest classification in the city at roughly 4,066 acres. It marks land not yet brought into development, and a station area variant of it covers a further 37 acres.
