Harrisburg ADU Permit Fees & Cost Calculator
Harrisburg appears to charge a residential application fee and uses a city fee schedule for building-related permits, but the available sources do not clearly expose a dedicated ADU fee schedule. Exact ADU-specific permit, plan review, inspection, and utility connection fees should be verified with the City of Harrisburg and relevant utilities/school district before budgeting.
