Trenton, NJ Home Business: Zoning & Home Occupation Permits (2026)

L, home occupations are permitted in a dwelling unit as an accessory use only if the use is "clearly incidental and secondary to the primary use of the dwelling for residential purposes" and does not adversely affect the surrounding residential district. The occupation can run out of the principal structure or a detached accessory structure, but no alteration may change the residential character of the dwelling, and no exterior display or activity may signal the home is being used for anything but residential purposes. Staffing is capped: family members occupying the dwelling plus no more than one non-resident worker may be present at any given time to work in connection with the home occupation.

Deliveries are limited to what a passenger vehicle, parcel courier, or mail carrier would typically bring; commodities requiring freight-style receipt are barred. Toxic, explosive, flammable, corrosive or radioactive materials cannot be used or stored on-site, and the operation cannot generate noise, odor, smoke, electrical interference or vibration beyond what is normal for residential use. Tractor trailers, semi-trucks and heavy construction equipment are prohibited, as is vehicle, machinery or engine repair, though small electronics repair such as computers is allowed. Rental services with on-site customer pickup, dispatching operations where workers report to the home, day cares, and firearm-transfer businesses are all expressly excluded from the home-occupation category and regulated elsewhere.

City Code § 146-35 lets a business that is both licensable and permitted under Chapter 315 register as a home-based business without a fee, but bars any application involving retail sale, and the license can be canceled by Code Enforcement or City Council for a zoning violation.
