Summary
Dayton allows home occupations only as an accessory use that stays undetectable from outside, capped at 25% of a dwelling's floor area.
The purpose of this sub-section is to set forth regulations, which control the establishment and operation of home occupations... Compliance with these regulations should result in all home occupations being located and conducted in such a manner that their existence is not detectable in any manner from the outside of the dwelling unit... no home occupation shall be permitted unless it complies with the following restrictions... (4) Not more than 25% of the floor area of a dwelling unit, and no more than 25% of any one floor shall be devoted to the home occupation.
Full Breakdown
Dayton's zoning code sets home occupations up as a controlled accessory use of a residential dwelling, meant to be limited enough that its existence isn't detectable from outside the home. No home occupation is permitted unless it complies with a list of restrictions in § 150.440, including a hard cap: no more than 25% of a dwelling unit's total floor area, and no more than 25% of any one floor, can be devoted to the business. The Zoning Administrator decides whether a proposed use meets the code's intent, and an operator must supply whatever information is needed to make that call.
Violations & Fines
Exceeding the 25% floor-area cap, or operating a use the Zoning Administrator finds inconsistent with the accessory-use purpose, means the home occupation isn't permitted under the zoning code.
