Jackson, NJ Accessory Structures: ADU Impact Fees (2026)

Section 244-12J establishes the Township's development fee under the amended Fair Housing Act and the Statewide Non-Residential Development Fee Act, with proceeds restricted to funding very-low-, low- and moderate-income housing under a court-approved spending plan through the Municipal Affordable Housing Trust Fund. While most residential development pays the 1.5% fee on equalized assessed value, § 244-12J(3)(a)[1] specifically extends that fee to accessory dwelling units, stating that development fees are imposed when an additional dwelling unit is added to an existing residential structure, calculated on the increase in the property's equalized assessed value attributable to that unit.

ADUs are currently a permitted accessory use only in the RG-3 Regional Growth Zone, where § 244-91G sets bulk standards, including no more than one ADU per lot, a minimum of two rooms, and its own required parking space. Within that same subsection, § 244-91G(4) offers an incentive: an ADU that complies with the state Uniform Housing Affordability Control Rules and carries an affordable-housing deed restriction for at least 10 years has its COAH residential development fee waived entirely. Outside of that affordability track, the fee applies at the standard 1.5% rate, separate from the steeper 6.0% "bonus" development fee that applies only when a density variance under N.J.S.A. 40:55D-70d(5) increases unit count.
