Summary
In unincorporated Sauk County, a home-based business permitted as an accessory use under Section 7.052 may draw no more than five patron vehicles a day, or 25 a week, whichever is greater, and never more than two parked at once. The Zoning Administrator ties the cap to the land use permit for the accessory use.
(j)The home-based business shall not exceed five patron related vehicles per day, or a maximum of 25 patron or business related vehicles per week, whichever is greater. Not more than two patron vehicles shall be present at one time, and the proprietor will provide adequate off-street parking on the property where the use is located. Parking areas shall not be used in determining gross floor area. ... (j)The home-based business shall not exceed ten patron or business related vehicles per day, or a maximum of 50 patron vehicles per week, whichever is greater. Not more than ten patron vehicles shall be present at one time, and the proprietor will provide adequate off-street parking on the property where the use is located.
Full Breakdown
Sauk County's Land Resources and Environment Department administers the home-based business standards at Sauk County Code § 7.052 for the unincorporated areas of Sauk County. A home-based business operated as an accessory use in the SFR, MFR, RUC, EA, AG, and RC zoning districts needs a land use permit from the Zoning Administrator before it opens, and Section 7.052(3)(j) caps customer traffic at five patron vehicle visits a day or 25 a week, whichever is greater, with no more than two patron vehicles present on the property at any one time.
The proprietor must supply adequate off-street parking, and that parking area cannot be counted toward the business's gross floor area limit. Businesses that instead go through the conditional use track available in the EA, RC, and AG districts under Section 7.052(4)(j) get a wider allowance: up to ten patron or business vehicles a day, or 50 a week, whichever is greater, with up to ten vehicles present at once. Both tracks also cap delivery truck visits at six a week and restrict operating hours, 8:00 a.m. to 8:00 p.m. for the land-use-permit tier and 8:00 a.m. to 10:00 p.m. for the conditional-use tier.
The traffic cap exists to keep neighboring residential lots from absorbing commercial-scale customer flow; a business that regularly draws more cars than the section allows is treated as exceeding the scope of its permit.
Violations & Fines
A home-based business that draws more traffic than its permit tier allows, or that never obtained the required land use permit, is enforced under Sauk County Code § 7.155: the Zoning Administrator can revoke the permit, and the Corporation Counsel can pursue injunctive relief plus a fine of $50.00 to $200.00 per day the violation continues, together with the cost of the action.
