Parsippany-Troy Hills, NJ Home Business: Zoning & Home Occupation Permits (2026)

Section 430-41A sits in the R-R Residential District article. The R-1 article adopts it through § 430-50A, the R-2 article through § 430-59A, and the R-3 and R-4 articles repeat the cross-reference to § 430-41 in its entirety. Three conditions apply. First, no display of goods is visible from the street. Second, there is no exterior advertising other than a small announcement sign as specified in Article XXXVIII. Third, the occupation is conducted in the main building by a person residing there and does not occupy more than 30% of the first floor, excluding space used for a private garage. In a split-level structure the space is limited to 30% of the first two levels.

The definition of CUSTOMARY HOME OCCUPATION in § 430-8 adds detail. It is an activity carried out for gain by a resident as a customary, incidental and accessory use in the resident's dwelling unit, other than a professional home office as defined in § 430-59B. The definition names home offices for an accountant, architect, dressmakers and tailors, engineer, land surveyor, lawyer or professional planner, but not doctors or other medical practitioners, provided the professional owns and occupies the unit and the use does not exceed 30% of the floor area. It also names individual music or singing teaching, individual private tutoring, portrait painting or sculpturing, and contractors using their homes to receive phone calls, provided there is no storage of construction equipment or materials at the property. A limousine owner can use the home to take appointments, provided no more than one nonmodified, standard-sized vehicle bearing a limousine license plate is parked there.

Signs are capped in Article XXXVIII. Section 430-280 exempts from permit and fee one professional nameplate or home occupation sign per parcel, indicating the name and profession of the occupant and not exceeding one square foot, not lighted outside posted business hours. Section 430-286 likewise limits the sign identifying a permitted home occupation to one square foot on any one side.

A physician, surgeon, dentist or similar professional falls under the separate professional home office conditional use in § 430-59B, which allows not more than one nonresident employee and limits office space to 30% of the area of any one floor.
