Fountain, CO Building Setbacks & Zoning: Lot Coverage Limits (2026)

Fountain does not set one citywide lot-coverage cap; each of the seventeen zoning districts in Chapter 17.04, Zoning Districts, carries its own maximum impervious coverage figure inside its dimensional requirements list. For the R1 single family residential small lot district, the district that covers most of Fountain's subdivided single-family neighborhoods, Section 17.04.030(C)(4) sets the limit at 35 percent, alongside a maximum density of six dwelling units per acre and a 6,000-square-foot minimum lot area per dwelling unit. The two larger-lot residential districts are more restrictive: the large lot agricultural/residential district and the residential agricultural district both cap impervious coverage at 25 percent under Sections 17.04.010(C)(4) and 17.04.020(C)(4). Coverage limits climb sharply in Fountain's commercial and industrial districts, up to 80 percent in the small office/warehouse, business park, and regional commercial districts, and 90 percent in the downtown mixed use and planned industrial districts, while the parks and open space district is capped at just 15 percent under Section 17.04.160(D)(3).

Impervious coverage is not separately defined in the district text, but Section 17.07.010(C) makes clear that the space needed to meet a lot's coverage requirement cannot be sold, transferred, or leased away from the lot, and non-conforming lots of record are still held to the coverage standard of the zoning district in which they sit under Section 17.07.020(B). All of these dimensional standards were most recently readopted as part of the citywide rewrite under Ordinance No. 1742 on January 14, 2020, and no variance from them is allowed except through the planned unit development, non-conforming use, or variance and appeals chapters.
