Ames, IA Home Business: Zoning & Home Occupation Permits (2026)

Sec. 29.1304, administered by the Department of Planning and Housing under Chapter 29's Article 13 additional-use standards, treats a Home Occupation as an allowed use in every zoning district with no zoning permit or business license required, provided the operator meets every criterion in the section; failing any one of them makes the use prohibited under Sec. 29.1304(4)(b). The area limitation caps the business at less than 50% of the gross floor area of the dwelling unit itself, though it may occupy 50% or more of a detached accessory structure, and the calculation excludes attics and buildings used only for animals.

Operational limits require the activity to leave the home looking and functioning like a residence: no emission of smoke, dust, odor, glare, noise, vibration, or electronic interference beyond what an ordinary household produces, detectable at the lot line. Hours for employees, clients, customers and deliveries run only between 6:30 a.m. and 7:00 p.m. Separate subsections not quoted here add caps on signage, vehicle trips, on-site parking, and the number of nonresident employees and clients present at once, and Sec. 29.1304(6) lists prohibited business types outright, such as auto repair, veterinary boarding beyond six animals, and firearm ranges.

There is no limit on how many Home Occupations one dwelling may run, but their cumulative impact together must still satisfy every criterion in the section.
