Parma, OH Home Business: Zoning & Home Occupation Permits (2026)

03(f), part of the accessory-use standards for the Single-Family House District, permits a home occupation only if it stays incidental to the residential use. No one but a household member may be employed on site, ruling out hired staff or subcontractors working from the house. The occupation must be conducted wholly within the dwelling itself, not in a detached garage, shed or yard, and it cannot occupy more than twenty-five percent of the dwelling unit's floor area, so a large finished basement cannot be converted entirely into a shop.

Only merchandise produced on the premises may be sold, which rules out reselling stock bought elsewhere. Equipment that creates 'objectionable disturbances beyond the premises' is barred, tying enforcement to a neighbor complaint standard the Building Department applies case by case. The use cannot alter the residential character of the dwelling's exterior and cannot require storing equipment, materials or vehicles outside the main building, so a contractor's trailer or pallets of supplies left in the driveway violate the section even if the work itself is legal.

20 separately defines 'home occupation' as any activity carried out for gain by a resident as an incidental or accessory use of the dwelling unit, and the accessory-use list expressly excludes 'uses permitted as commercial or industrial uses,' so a use zoned only for a business district cannot relocate into a house by calling itself a home occupation. Because Chapter 1153 governs the Single-Family House District and Chapter 1155 extends the same conditional-use framework to Two-Family House Districts, these eight conditions apply across most of Parma's residential zoning.
