Zoning regulations are rules that define how a property can be used. The purpose of the zoning regulations is to implement the Larimer County Comprehensive Plan, promote compatible land use patterns and establish standards appropriate for each zoning district. 

See the table below for a list of Larimer County's zoning districts (the number indicates its section number in the Larimer County Land Use Code).

Larimer County is divided into two areas ("B" & "C") by wildfire hazard area and roofing requirements. Area "B" is the foothill and mountain areas; area "C" is along the Front Range. Due to the prevalence of shrink/swell soils in Larimer County, especially along the Front Range, an engineered footing and foundation plan or a site-specific soils report indicating non-expansive soil will be required on all home sites in area "C".
