Summary
Dublin, California requires a City Business License before operating any Home Occupation in a residential zoning district, per Dublin Municipal Code §8.64.020, and the activity must stay incidental and subordinate to the residential use, confined to one indoor room, without changing the home's exterior appearance or the neighborhood's residential character (§8.64.010, §8.64.030).
The purpose of this Chapter is to allow Home Occupations for the gainful employment of the occupant of a dwelling in a limited commercial activity, with such employment activity being incidental and subordinate to the residential use of the property. The intent of this Chapter is to ensure that Home Occupations are compatible with, and do not change the character of, the surrounding residential area by generating more traffic, noise, odors, visual impacts, or storage of materials than would normally be expected in a residential zoning district. ... Business licenses are required for Home Occupations which are permitted as accessory uses in all residential zoning districts. No Home Occupation may be conducted until a Business License is issued pursuant to Chapter 4.04 (Business Registration).
