Full Breakdown
Larimer County's Land Use Code sets minimum setbacks per zoning district.

Conservation and agriculture districts (A, FO) require 25 front and 15 side/rear. Detached accessory buildings 200 square feet or less may be placed in a rear or side setback but must keep 5 feet from all lot lines. Road setbacks are larger: from state and federal highways, 100 feet from the right-of-way centerline or 50 feet from the right-of-way line, whichever is greater. Streams, creeks, and rivers require a 100-foot setback from centerline.
