Longmont, 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. Longmont's ordinance does not state permitted uses as citywide flags, so they are read from each district's own table rather than summarised here.

City Context

How is Longmont zoned?

Longmont regulates land through 15 zoning districts, a compact roster that covers the full range without proliferation. Residential Single Family is the largest at roughly 4,220 acres, followed by Public Facilities at about 3,581 and Agricultural at roughly 2,737.

The most notable feature is how much of the roster is mixed use. Five of the fifteen districts are mixed use: employment, regional center, corridor, downtown and neighborhood. Together they cover over two thousand acres, and they are distinguished by the role of the area rather than by the uses permitted. For a city of this size, dedicating a third of the district roster to mixed use is a deliberate structural choice.

The residential side is equally economical. Beyond single family sit a Residential Mixed Neighborhood district at roughly 1,724 acres, a multifamily district at about 473, a rural district at roughly 148 and a mobile home district at about 73. The mixed neighborhood district is the second largest residential classification, which suggests the city expects varied housing types within neighborhoods rather than uniform blocks.

Employment land is handled through a Primary Employment district of roughly 1,334 acres alongside the mixed use employment district. Planned Unit Development covers about 334 acres, with a Terry Lake overlay variant adding roughly 132. Longmont 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.
