Madison FAQ
How many garage sales can I have per year in Madison?
There is no specific annual limit on garage sales. However, holding sales very frequently could be considered a commercial activity, which would require a Madison business license.
At what point does a garage sale become a business?
The city does not publish a specific number. If your sales become regular or ongoing rather than occasional, you may be considered to be conducting a commercial retail operation that requires licensing.
Sun Prairie FAQ
Can I hold weekly garage sales during summer in Madison?
Madison lacks a strict numeric cap, but weekly sales will trigger zoning enforcement as a de facto retail operation under MGO 28.151 and require a home-occupation permit and Wisconsin seller's permit.
Do estate sales count toward the annual limit?
Most Dane County municipalities treat bona fide estate sales (to liquidate a deceased person's property) as a separate category not counting toward frequency limits. Check with your municipal clerk for specifics.
