Trenton ADU Permit Fees & Cost Calculator
Trenton’s municipal code appears to allow accessory dwelling units, but the available official materials do not clearly expose a dedicated ADU fee schedule. The most reliable next step is to verify Trenton’s current building permit, plan review, zoning, and utility connection fees directly with the city and serving utilities before budgeting an ADU project.

Fee overview
The available source extract does not include exact dollar amounts, so numeric fees are intentionally left null.
Trenton-specific utility, school, and any special assessment charges must be verified directly with the city, school district, and serving utilities before budgeting.
Because New Jersey ADU regulation is still patchy by municipality, confirm that the property’s zoning district and ADU type are permitted before relying on fee estimates.
Trenton uses a standard municipal permit and review process for ADUs rather than a dedicated ADU fee schedule.
Any school-related or impact-related charges, if applicable, were not identifiable from the available official sources and may depend on project scope or utility district rules.
Trenton fee estimates should be verified against the current city, utility, and school district fee schedules before filing.
