Summary

In unincorporated Cass County, a garage sale sign is exempt from the Zoning Order's sign permit and size rules under Section 400.780(A)(9), but only 'for a period not to exceed three (3) days.' Put the sign up and take it down within that window or it becomes an unpermitted temporary sign under Article XII.

These county ordinances apply to unincorporated areas of Cass County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

The following signs shall be exempt from the requirements of this Article: ... Temporary event signs, including signs for the sale of household goods at a residence (garage sale) for a period not to exceed three (3) days;

Full Breakdown

790. Item 9 groups four exemptions in one sentence: garage-sale signs, real estate signs up to sixteen square feet, construction signs up to thirty-two square feet, and political campaign signs up to thirty-two square feet. The garage-sale exemption is narrower than the others in one respect: it carries a hard duration cap, 'a period not to exceed three (3) days,' rather than a size cap. 770 permit track. Because the Zoning Order does not separately license or cap how many garage sales a household may hold, the three-day figure is the operative limit for anyone in unincorporated Cass County advertising a sale with a yard sign: display it once the sale starts and remove it within three days, regardless of how the sale itself is scheduled.

Violations & Fines

A garage-sale sign left up past the three-day window in Section 400.780(A)(9) loses its exemption and becomes an unpermitted sign under Section 400.720(A)(2), which the Code treats as a violation of the Zoning Order enforced under Section 400.030(22). The Zoning Officer gives written notice, the owner has 10 days to remove it, and an uncorrected violation can bring a misdemeanor conviction and fines up to $1,000 per day.

Frequently Asked Questions

How long can I keep my garage sale sign up in unincorporated Cass County?
Three days. Section 400.780(A)(9) exempts 'signs for the sale of household goods at a residence (garage sale)' from the Zoning Order's sign permit and size rules only 'for a period not to exceed three (3) days.' No permit or fee applies within that window, but the sign has to come down once the three days are up, regardless of whether the sale itself runs longer.
Do I need a sign permit for a garage sale sign?
No, as long as you stay inside the three-day limit in Section 400.780(A)(9). That section lists garage-sale signs among the types 'exempt from the requirements of this Article,' meaning the normal Section 400.720 permit-and-fee process for signs does not apply. Leave the sign up longer than three days and it becomes an unpermitted sign subject to enforcement.
What happens if I leave my garage sale sign up too long?
It stops being exempt and becomes an unpermitted sign under Section 400.720(A)(2), which the Zoning Order treats as a violation enforced through Section 400.030(22). The Zoning Officer notifies the owner, who then has ten days to remove it; an uncorrected violation can be referred to court, where a misdemeanor conviction carries fines the Commission can set up to $1,000 for each day the sign remains.
