One sign, maximum 4 square feet in area per face and six feet in height. The sign can be located anywhere on the lot, except in a road right-of-way (i.e., not on a mailbox in the right-of-way).
Full Breakdown
Larimer County limits home-occupation signage to a single sign no larger than 4 square feet in area per face and no taller than six feet. Placement is flexible across the lot but cannot encroach into a public road right-of-way, which rules out mounting on a mailbox in the right-of-way. This is tighter than commercial sign allowances because the home occupation must preserve the residential character of the property. Fort Collins, Loveland, and other incorporated cities apply their own sign codes within their limits.
Violations & Fines
An oversized, second, or right-of-way sign is a code violation; the county can require removal through zoning enforcement.
