Full Breakdown
Plainfield Municipal Code § 17:9-33 allows home occupations as an accessory use to any residence in the City of Plainfield, Union County, unless the chapter specifies otherwise. Every home occupation needs an approved development permit before use begins, which the Zoning Officer issues under Chapter 17.
The controlling test in subsection A is character. A home occupation cannot change the principal residence from a home to a business, or change the surrounding neighborhood from residential to commercial. The home occupation cannot differ from what is expected in a residential neighborhood in four areas: the appearance of the premises, including color, materials, construction or lighting; the risk of physical harm to persons or property from the nature or volume of materials stored on site; the creation of noise, vibration, dust, smoke, odor, glare, radiation or electrical interference; and the volume and frequency of vehicular or pedestrian traffic.
The numeric limits follow. Only one home occupation can run on a lot, and it cannot involve more than thirty percent of the gross floor area of the principal dwelling unit, counting the floor area of an attached garage. No more than one person other than the occupants of the dwelling can be involved or employed on the premises. The work must happen entirely within the principal residence, with no outdoor storage or activities, and commercial vehicles are excluded except for an occasional cartage vehicle delivering materials to or from the premises.
Related sections reinforce the limits. Section 17:9-41 prohibits storage for commercial uses in residential zones and bars outdoor storage beyond what is customary for a residence. Section 17:9-34 limits a private garage to one commercial vehicle with a rated capacity not exceeding eight thousand five hundred pounds gross vehicle weight.
Violations & Fines
Operating without the development permit, or outside the limits above, violates Chapter 17. Section 17:1-23 sets a court-determined penalty of not more than $1,500 for the first ten days after the initial summons and not more than $75 per day after that. The Zoning Officer first sends a letter requesting compliance within ten days, then a certified letter, and then issues a summons prosecuted in Municipal Court, reissued every ten days while the violation continues.
