Fountain, CO Accessory Structures: Shed & Carport Rules (2026)

Fountain's general accessory-structure standard, Section 17.07.050(B), applies to sheds, detached garages, and similar structures across every zoning district unless Chapter 17.04 sets a different number for that district. It requires a minimum 12-foot setback from the rear lot line, the same front and side yard setbacks that apply to the principal dwelling on the lot, and at least six feet of separation from the principal building unless the accessory structure is attached to it. Accessory structures must also meet whatever bulk regulations, height and coverage limits, apply in their zoning district. In the R1 single-family district, this 12-foot standard lines up with the district's own accessory-building rear setback under Section 17.04.030(C)(8); the LLR and RA agricultural districts instead list sheds, barns, and similar structures as permitted accessory uses without a separate numeric rear setback in the district text itself, so the Chapter 17.07 default controls there.

Fountain treats one accessory structure differently in detail: pre-manufactured or membrane carports. Section 17.13.060 requires a plot plan showing the carport's setbacks, structural height, and lot coverage; carports under 200 square feet are exempt from zone-district development standards, though they must still be anchored to the ground, while carports over 200 square feet must meet all zone-district setback, coverage, and height standards and obtain a building permit from the Pikes Peak Regional Building Department. Attached carports and any site-built, wood-framed carport need a permit regardless of size, and only one carport is allowed per property. Architectural review under Section 17.13.040 additionally requires metal accessory buildings to be color-matched to the main house and to include at least 25 percent non-metal exterior material on sides visible from the street or a neighboring residence.
