Summary
A home-based auto repair or other service business in unincorporated Story County is governed by the county's service-vehicle parking standard in the Land Development Regulations. In the A-1 Agricultural District, no more than two service vehicles may sit outside at once; in the AR, R-1 and R-2 residential districts, every service vehicle used by the business must be fully enclosed inside a building.
G. Parking of service vehicles as defined in Section 85.08, Definitions, is subject to the following requirements: (1) Not more than two service vehicles may be parked at one time outside the home business located in the A-1 Agricultural District. (2) Service vehicles not in use may be permitted in areas visible from the road right-of-way and adjacent properties when the property is zoned A-1 Agricultural. (3) In the A-R Agricultural Residential, R-1 Transitional Residential, and R-2 Urban Residential Districts, all service vehicles shall be fully enclosed within a building.
Full Breakdown
01(1)(G) of the Land Development Regulations directly limits how a home-based service business, including auto repair, can store its work vehicles in unincorporated Story County. 08, may be parked outside the home business at one time, and vehicles not in use may sit in areas visible from the road or neighboring properties. On land zoned A-R Agricultural Residential, R-1 Transitional Residential or R-2 Urban Residential, that visibility allowance disappears: every service vehicle must be fully enclosed within a building, with no outdoor parking permitted at all.
Auto repair operations also fall under the general home business standards: outside storage or display of parts and products is banned, and any hazardous chemicals or substances involved, such as solvents, fuels or oils, must be disclosed on the Home Business Permit application so the Story County Emergency Management Agency and the applicable fire chief can review the risk to neighboring properties. The Story County Environmental Health Department also reviews the business's effect on the property's private sewage disposal system under Chapter 65 before a permit issues.
A home business that would be a principal use in the HI Heavy Industrial District, or that stores or distributes chemicals like liquid propane or anhydrous ammonia, cannot qualify as a home business at all and must locate in a commercial or industrial district instead.
Violations & Fines
Operating a home auto repair business with service vehicles parked or stored outside these limits violates Section 89.01(1) and is enforced under Section 92.11 and Chapter 93. An authorized county employee who witnesses the violation can issue a citation carrying a civil penalty of up to $750 for a first offense and up to $1,000 for each repeat offense, and the Planning and Development Director may require follow-up inspections.
